Nutrition Recommendations and Interventions for Diabetes
A preliminary analysis of selected legal provisions in those countries where complementary foods are listed as designated products in their Code-related legislation is also documented. If these products are used, they should displace, rather than be added to, the diet to avoid weight gain. Instead of having 9 different bottles of products on your counter, which can be very expensive, MELABIC has the power punch of all nine combined. C The ADA recognizes that education about glycemic index and glycemic load occurs during the development of individualized eating plans for people with diabetes. Observational studies suggest a U- or J-shaped association between moderate consumption of alcohol one to three drinks [15—45 g alcohol] per day and decreased risk of type 2 diabetes 41 , 42 , coronary heart disease CHD 42 , 43 , and stroke Many people with diabetes, as well as their health care provider s , are not aware that these services are available to them.

Cashews Nutrition: Helps Prevent Cancer, Diabetes & More

Although brain fuel needs can be met on lower-carbohydrate diets, long-term metabolic effects of very-low-carbohydrate diets are unclear, and such diets eliminate many foods that are important sources of energy, fiber, vitamins, and minerals and are important in dietary palatability Meal replacements liquid or solid prepackaged provide a defined amount of energy, often as a formula product.

Use of meal replacements once or twice daily to replace a usual meal can result in significant weight loss.

However, meal replacement therapy must be continued indefinitely if weight loss is to be maintained. When very-low-calorie diets are stopped and self-selected meals are reintroduced, weight regain is common.

Thus, very-low-calorie diets appear to have limited utility in the treatment of type 2 diabetes and should only be considered in conjunction with a structured weight loss program. All cardiovascular risk factors except hypercholesterolemia improved in the surgical patients. Individuals at high risk for type 2 diabetes should be encouraged to achieve the U.

There is not sufficient, consistent information to conclude that low—glycemic load diets reduce the risk for diabetes. Nevertheless, low—glycemic index foods that are rich in fiber and other important nutrients are to be encouraged.

Observational studies report that moderate alcohol intake may reduce the risk for diabetes, but the data do not support recommending alcohol consumption to individuals at risk of diabetes.

Although there are insufficient data at present to warrant any specific recommendations for prevention of type 2 diabetes in youth, it is reasonable to apply approaches demonstrated to be effective in adults, as long as nutritional needs for normal growth and development are maintained. The importance of preventing type 2 diabetes is highlighted by the substantial worldwide increase in the prevalence of diabetes in recent years.

Genetic susceptibility appears to play a powerful role in the occurrence of type 2 diabetes. However, given that population gene pools shift very slowly over time, the current epidemic of diabetes likely reflects changes in lifestyle leading to diabetes. Lifestyle changes characterized by increased energy intake and decreased physical activity appear to have together promoted overweight and obesity, which are strong risk factors for diabetes. Several studies have demonstrated the potential for moderate, sustained weight loss to substantially reduce the risk for type 2 diabetes, regardless of whether weight loss was achieved by lifestyle changes alone or with adjunctive therapies such as medication or bariatricsurgery see energy balance section 1.

Moreover, both moderate-intensity and vigorous exercise can improve insulin sensitivity, independent of weight loss, and reduce risk for type 2 diabetes 1.

S 26 strongly support the potential for moderate weight loss to reduce the risk for type 2 diabetes. In addition to preventing diabetes, the DPP lifestyle intervention improved several CVD risk factors, including dsylipidemia, hypertension, and inflammatory markers 29 , The DPP analysis indicated that lifestyle intervention was cost-effective 31 , but other analyses suggest that the expected costs needed to be reduced Both the Finnish Diabetes Prevention study and the DPP focused on reduced intake of calories using reduced dietary fat as a dietary intervention.

Of note, reduced intake of fat, particularly saturated fat, may reduce risk for diabetes by producing an energy-independent improvement in insulin resistance 1 , 33 , 34 , as well as by promoting weight loss. It is possible that reduction in other macronutrients e. Several studies have provided evidence for reduced risk of diabetes with increased intake of whole grains and dietary fiber 1 , 35 — Whole grain—containing foods have been associated with improved insulin sensitivity, independent of body weight, and dietary fiber has been associated with improved insulin sensitivity and improved ability to secrete insulin adequately to overcome insulin resistance There is debate as to the potential role of low—glycemic index and —glycemic load diets in prevention of type 2 diabetes.

Thus, there is not sufficient, consistent information to conclude that low—glycemic load diets reduce risk for diabetes. Prospective randomized clinical trials will be necessary to resolve this issue. A American Diabetes Association statement reviewed this issue in depth 40 , and issues related to the role of glycemic index and glycemic load in diabetes management are addressed in more detail in the carbohydrate section of this document.

Observational studies suggest a U- or J-shaped association between moderate consumption of alcohol one to three drinks [15—45 g alcohol] per day and decreased risk of type 2 diabetes 41 , 42 , coronary heart disease CHD 42 , 43 , and stroke However, heavy consumption of alcohol greater than three drinks per day , may be associated with increased incidence of diabetes If alcohol is consumed, recommendations from the USDA Dietary Guidelines for Americans suggest no more than one drink per day for women and two drinks per day for men Although selected micronutrients may affect glucose and insulin metabolism, to date, there are no convincing data that document their role in the development of diabetes.

No nutrition recommendations can be made for the prevention of type 1 diabetes at this time 1. Increasing overweight and obesity in youth appears to be related to the increased prevalence of type 2 diabetes, particularly in minority adolescents. Although there are insufficient data at present to warrant any specific recommendations for the prevention of type 2 diabetes in youth, interventions similar to those shown to be effective for prevention of type 2 diabetes in adults lifestyle changes including reduced energy intake and regular physical activity are likely to be beneficial.

Clinical trials of such interventions are ongoing in children. A dietary pattern that includes carbohydrate from fruits, vegetables, whole grains, legumes, and low-fat milk is encouraged for good health.

Monitoring carbohydrate, whether by carbohydrate counting, exchanges, or experienced-based estimation remains a key strategy in achieving glycemic control. The use of glycemic index and load may provide a modest additional benefit over that observed when total carbohydrate is considered alone. Sucrose-containing foods can be substituted for other carbohydrates in the meal plan or, if added to the meal plan, covered with insulin or other glucose-lowering medications.

Care should be taken to avoid excess energy intake. As for the general population, people with diabetes are encouraged to consume a variety of fiber-containing foods.

However, evidence is lacking to recommend a higher fiber intake for people with diabetes than for the population as a whole. Sugar alcohols and nonnutritive sweeteners are safe when consumed within the daily intake levels established by the Food and Drug Administration FDA. Control of blood glucose in an effort to achieve normal or near-normal levels is a primary goal of diabetes management. Food and nutrition interventions that reduce postprandial blood glucose excursions are important in this regard, since dietary carbohydrate is the major determinant of postprandial glucose levels.

Low-carbohydrate diets might seem to be a logical approach to lowering postprandial glucose. However, foods that contain carbohydrate are important sources of energy, fiber, vitamins, and minerals and are important in dietary palatability. Therefore, these foods are important components of the diet for individuals with diabetes. Issues related to carbohydrate and glycemia have previously been extensively reviewed in American Diabetes Association reports and nutrition recommendations for the general public 1 , 2 , 22 , 40 , Blood glucose concentration following a meal is primarily determined by the rate of appearance of glucose in the blood stream digestion and absorption and its clearance from the circulation Insulin secretory response normally maintains blood glucose in a narrow range, but in individuals with diabetes, defects in insulin action, insulin secretion, or both impair regulation of postprandial glucose in response to dietary carbohydrate.

Both the quantity and the type or source of carbohydrates found in foods influence postprandial glucose levels. A ADA statement addressed the effects of the amount and type of carbohydrate in diabetes management The 1-year follow-up data also indicate that the macronutrient composition of the treatment groups only differed with respect to carbohydrate intake mean intake of vs.

Thus, questions about the long-term effects on intake and metabolism, as well as safety, need further research. The amount of carbohydrate ingested is usually the primary determinant of postprandial response, but the type of carbohydrate also affects this response.

Intrinsic variables that influence the effect of carbohydrate-containing foods on blood glucose response include the specific type of food ingested, type of starch amylose versus amylopectin , style of preparation cooking method and time, amount of heat or moisture used , ripeness, and degree of processing.

Extrinsic variables that may influence glucose response include fasting or preprandial blood glucose level, macronutrient distribution of the meal in which the food is consumed, available insulin, and degree of insulin resistance. The glycemic index of foods was developed to compare the postprandial responses to constant amounts of different carbohydrate-containing foods The glycemic index of a food is the increase above fasting in the blood glucose area over 2 h after ingestion of a constant amount of that food usually a g carbohydrate portion divided by the response to a reference food usually glucose or white bread.

The glycemic loads of foods, meals, and diets are calculated by multiplying the glycemic index of the constituent foods by the amounts of carbohydrate in each food and then totaling the values for all foods.

Foods with low glycemic indexes include oats, barley, bulgur, beans, lentils, legumes, pasta, pumpernickel coarse rye bread, apples, oranges, milk, yogurt, and ice cream. Fiber, fructose, lactose, and fat are dietary constituents that tend to lower glycemic response.

Potential methodological problems with the glycemic index have been noted Several randomized clinical trials have reported that low—glycemic index diets reduce glycemia in diabetic subjects, but other clinical trials have not confirmed this effect Moreover, the variability in responses to specific carbohydrate-containing food is a concern Nevertheless, a recent meta-analysis of low—glycemic index diet trials in diabetic subjects showed that such diets produced a 0.

However, it appears that most individuals already consume a moderate—glycemic index diet 39 , Thus, it appears that in individuals consuming a high—glycemic index diet, low—glycemic index diets can produce a modest benefit in controlling postprandial hyperglycemia. In diabetes management, it is important to match doses of insulin and insulin secretagogues to the carbohydrate content of meals.

A variety of methods can be used to estimate the nutrient content of meals, including carbohydrate counting, the exchange system, and experience-based estimation. By testing pre- and postprandial glucose, many individuals use experience to evaluate and achieve postprandial glucose goals with a variety of foods.

To date, research has not demonstrated that one method of assessing the relationship between carbohydrate intake and blood glucose response is better than other methods. Palatability, limited food choices, and gastrointestinal side effects are potential barriers to achieving such high-fiber intakes. Substantial evidence from clinical studies demonstrates that dietary sucrose does not increase glycemia more than isocaloric amounts of starch 1.

Thus, intake of sucrose and sucrose-containing foods by people with diabetes does not need to be restricted because of concern about aggravating hyperglycemia. Sucrose can be substituted for other carbohydrate sources in the meal plan or, if added to the meal plan, adequately covered with insulin or another glucose-lowering medication.

Additionally, intake of other nutrients ingested with sucrose, such as fat, need to be taken into account, and care should be taken to avoid excess energy intake. In individuals with diabetes, fructose produces a lower postprandial glucose response when it replaces sucrose or starch in the diet; however, this benefit is tempered by concern that fructose may adversely affect plasma lipids 1. Therefore, the use of added fructose as a sweetening agent in the diabetic diet is not recommended.

There is, however, no reason to recommend that people with diabetes avoid naturally occurring fructose in fruits, vegetables, and other foods. Reduced calorie sweeteners approved by the FDA include sugar alcohols polyols such as erythritol, isomalt, lactitol, maltitol, mannitol, sorbitol, xylitol, tagatose, and hydrogenated starch hydrolysates.

Studies of subjects with and without diabetes have shown that sugar alcohols produce a lower postprandial glucose response than sucrose or glucose and have lower available energy 1. When calculating carbohydrate content of foods containing sugar alcohols, subtraction of half the sugar alcohol grams from total carbohydrate grams is appropriate.

Use of sugar alcohols as sweeteners reduces the risk of dental caries. However, there is no evidence that the amounts of sugar alcohols likely to be consumed will reduce glycemia, energy intake, or weight. The use of sugar alcohols appears to be safe; however, they may cause diarrhea, especially in children. The FDA has approved five nonnutritive sweeteners for use in the U. These are acesulfame potassium, aspartame, neotame, saccharin, and sucralose.

Before being allowed on the market, all underwent rigorous scrutiny and were shown to be safe when consumed by the public, including people with diabetes and women during pregnancy.

Clinical studies involving subjects without diabetes provide no indication that nonnutritive sweeteners in foods will cause weight loss or weight gain It has been proposed that foods containing resistant starch starch physically enclosed within intact cell structures as in some legumes, starch granules as in raw potato, and retrograde amylose from plants modified by plant breeding to increase amylose content or high-amylose foods, such as specially formulated cornstarch, may modify postprandial glycemic response, prevent hypoglycemia, and reduce hyperglycemia.

However, there are no published long-term studies in subjects with diabetes to prove benefit from the use of resistant starch. Two or more servings of fish per week with the exception of commercially fried fish filets provide n-3 polyunsaturated fatty acids and are recommended.

The primary goal with respect to dietary fat in individuals with diabetes is to limit saturated fatty acids, trans fatty acids, and cholesterol intakes so as to reduce risk for CVD.

Saturated and trans fatty acids are the principal dietary determinants of plasma LDL cholesterol. In nondiabetic individuals, reducing saturated and trans fatty acids and cholesterol intakes decreases plasma total and LDL cholesterol. Reducing saturated fatty acids may also reduce HDL cholesterol. Studies in individuals with diabetes demonstrating the effects of specific percentages of dietary saturated and trans fatty acids and specific amounts of dietary cholesterol on plasma lipids are not available.

Therefore, because of a lack of specific information, it is recommended that the dietary goals for individuals with diabetes be the same as for individuals with preexisting CVD, since the two groups appear to have equivalent cardiovascular risk. In metabolic studies in which energy intake and weight are held constant, diets low in saturated fatty acids and high in either carbohydrate or cis -monounsaturated fatty acids lowered plasma LDL cholesterol equivalently 1 , However, high—monounsaturated fat diets have not been shown to improve fasting plasma glucose or A1C values.

In other studies, when energy intake was reduced, the adverse effects of high-carbohydrate diets were not observed 53 , Individual variability in response to high-carbohydrate diets suggests that the plasma triglyceride response to dietary modification should be monitored carefully, particularly in the absence of weight loss. Diets high in polyunsaturated fatty acids appear to have effects similar to monounsaturated fatty acids on plasma lipid concentrations 55 , 56 — Very-long-chain n-3 polyunsaturated fatty acid supplements have been shown to lower plasma triglyceride levels in individuals with type 2 diabetes who are hypertriglyceridemic.

Although the accompanying small rise in plasma LDL cholesterol is of concern, an increase in HDL cholesterol may offset this concern Glucose metabolism is not likely to be adversely affected. Very-long-chain n-3 polyunsaturated fatty acid studies in individuals with diabetes have primarily used fish oil supplements.

In addition to providing n-3 fatty acids, fish frequently displace high—saturated fat—containing foods from the diet Two or more servings of fish per week with the exception of commercially fried fish filets 63 , 64 can be recommended.

Plant sterol and stanol esters block the intestinal absorption of dietary and biliary cholesterol. A wide range of foods and beverages are now available that contain plant sterols.

If these products are used, they should displace, rather than be added to, the diet to avoid weight gain.

Soft gel capsules containing plant sterols are also available. In individuals with type 2 diabetes, ingested protein can increase insulin response without increasing plasma glucose concentrations. Therefore, protein should not be used to treat acute or prevent nighttime hypoglycemia. High-protein diets are not recommended as a method for weight loss at this time. Although such diets may produce short-term weight loss and improved glycemia, it has not been established that these benefits are maintained long term, and long-term effects on kidney function for persons with diabetes are unknown.

The RDA is 0. Good-quality protein sources are defined as having high PDCAAS protein digestibility—corrected amino acid scoring pattern scores and provide all nine indispensable amino acids. Examples are meat, poultry, fish, eggs, milk, cheese, and soy. In meal planning, protein intake should be greater than 0.

A number of studies in healthy individuals and in individuals with type 2 diabetes have demonstrated that glucose produced from ingested protein does not increase plasma glucose concentration but does produce increases in serum insulin responses 1 , Abnormalities in protein metabolism may be caused by insulin deficiency and insulin resistance; however, these are usually corrected with good blood glucose control However, the effects of high-protein diets on long-term regulation of energy intake, satiety, weight, and the ability of individuals to follow such diets long term have not been adequately studied.

Dietary protein and its relationships to hypoglycemia and nephropathy are addressed in later sections. Although numerous studies have attempted to identify the optimal mix of macronutrients for the diabetic diet, it is unlikely that one such combination of macronutrients exists. The best mix of carbohydrate, protein, and fat appears to vary depending on individual circumstances.

For those individuals seeking guidance as to macronutrient distribution in healthy adults, the Dietary Reference Intakes DRIs may be helpful It must be clearly recognized that regardless of the macronutrient mix, total caloric intake must be appropriate to weight management goals. Further, individualization of the macronutrient composition will depend on the metabolic status of the patient e. If adults with diabetes choose to use alcohol, daily intake should be limited to a moderate amount one drink per day or less for women and two drinks per day or less for men.

To reduce risk of nocturnal hypoglycemia in individuals using insulin or insulin secretagogues, alcohol should be consumed with food. In individuals with diabetes, moderate alcohol consumption when ingested alone has no acute effect on glucose and insulin concentrations but carbohydrate coingested with alcohol as in a mixed drink may raise blood glucose.

Abstention from alcohol should be advised for people with a history of alcohol abuse or dependence, women during pregnancy, and people with medical problems such as liver disease, pancreatitis, advanced neuropathy, or severe hypertriglyceridemia. If individuals choose to use alcohol, intake should be limited to a moderate amount less than one drink per day for adult women and less than two drinks per day for adult men.

One alcohol containing beverage is defined as 12 oz beer, 5 oz wine, or 1. Moderate amounts of alcohol, when ingested with food, have minimal acute effects on plasma glucose and serum insulin concentrations However, carbohydrate coingested with alcohol may raise blood glucose. For individuals using insulin or insulin secretagogues, alcohol should be consumed with food to avoid hypoglycemia.

Evening consumption of alcohol may increase the risk of nocturnal and fasting hypoglycemia, particularly in individuals with type 1 diabetes Occasional use of alcoholic beverages should be considered an addition to the regular meal plan, and no food should be omitted. Excessive amounts of alcohol three or more drinks per day , on a consistent basis, contributes to hyperglycemia In individuals with diabetes, light to moderate alcohol intake one to two drinks per day; 15—30 g alcohol is associated with a decreased risk of CVD The type of alcohol-containing beverage consumed does not appear to make a difference.

There is no clear evidence of benefit from vitamin or mineral supplementation in people with diabetes compared with the general population who do not have underlying deficiencies. Routine supplementation with antioxidants, such as vitamins E and C and carotene, is not advised because of lack of evidence of efficacy and concern related to long-term safety.

Benefit from chromium supplementation in individuals with diabetes or obesity has not been clearly demonstrated and therefore can not be recommended. Uncontrolled diabetes is often associated with micronutrient deficiencies Individuals with diabetes should be aware of the importance of acquiring daily vitamin and mineral requirements from natural food sources and a balanced diet. Health care providers should focus on nutrition counseling rather than micronutrient supplementation in order to reach metabolic control of their patients.

Research including long-term trials is needed to assess the safety and potentially beneficial role of chromium, magnesium, and antioxidant supplements and other complementary therapies in the management of type 2 diabetes 71a , 71b.

In select groups such as the elderly, pregnant or lactating women, strict vegetarians, or those on calorie-restricted diets, a multivitamin supplement may be needed 1.

Since diabetes may be a state of increased oxidative stress, there has been interest in antioxidant therapy. Unfortunately, there are no studies examining the effects of dietary intervention on circulating levels of antioxidants and inflammatory biomarkers in diabetic volunteers.

The few small clinical studies involving diabetes and functional foods thought to have high antioxidant potential e. Clinical trial data not only indicate the lack of benefit with respect to glycemic control and progression of complications but also provide evidence of the potential harm of vitamin E, carotene, and other antioxidant supplements 1 , 72 , In addition, available data do not support the use of antioxidant supplements for CVD risk reduction Chromium, potassium, magnesium, and possibly zinc deficiency may aggravate carbohydrate intolerance.

Serum levels can readily detect the need for potassium or magnesium replacement, but detecting deficiency of zinc or chromium is more difficult In the late s, two randomized placebo-controlled studies in China found that chromium supplementation had beneficial effects on glycemia 76 — 78 , but the chromium status of the study populations was not evaluated either at baseline or following supplementation.

Data from recent small studies indicate that chromium supplementation may have a role in the management of glucose intolerance, gestational diabetes mellitus GDM , and corticosteroid-induced diabetes 76 — However, other well-designed studies have failed to demonstrate any significant benefit of chromium supplementation in individuals with impaired glucose intolerance or type 2 diabetes 79 , Similarly, a meta-analysis of randomized controlled trials failed to demonstrate any benefit of chromium picolinate supplementation in reducing body weight The FDA concluded that although a small study suggested that chromium picolinate may reduce insulin resistance, the existence of such a relationship between chromium picolinate and either insulin resistance or type 2 diabetes was uncertain http: There is insufficient evidence to demonstrate efficacy of individual herbs and supplements in diabetes management In addition, commercially available products are not standardized and vary in the content of active ingredients.

Herbal preparations also have the potential to interact with other medications Therefore, it is important that health care providers be aware when patients with diabetes are using these products and look for unusual side effects and herb-drug or herb-herb interactions. Individuals using rapid-acting insulin by injection or an insulin pump should adjust the meal and snack insulin doses based on the carbohydrate content of the meals and snacks.

For individuals using fixed daily insulin doses, carbohydrate intake on a day-to-day basis should be kept consistent with respect to time and amount. For planned exercise, insulin doses can be adjusted. For unplanned exercise, extra carbohydrate may be needed. The first nutrition priority for individuals requiring insulin therapy is to integrate an insulin regimen into their lifestyle. For individuals receiving basal-bolus insulin therapy, the total carbohydrate content of meals and snacks is the major determinant of bolus insulin doses Insulin-to-carbohydrate ratios can be used to adjust mealtime insulin doses.

Several methods can be used to estimate the nutrient content of meals, including carbohydrate counting, the exchange system, and experience-based estimation. Improvement in A1C without a significant increase in severe hypoglycemia was demonstrated, as were positive effects on quality of life, satisfaction with treatment, and psychological well-being, even though increases in the number of insulin injections and blood glucose tests were necessary.

For planned exercise, reduction in insulin dosage is the preferred method to prevent hypoglycemia For unplanned exercise, intake of additional carbohydrate is usually needed.

More carbohydrate is needed for intense activity. A American Diabetes Association statement addresses diabetes MNT for children and adolescents with type 1 diabetes Individuals with type 2 diabetes are encouraged to implement lifestyle modifications that reduce intakes of energy, saturated and trans fatty acids, cholesterol, and sodium and to increase physical activity in an effort to improve glycemia, dyslipidemia, and blood pressure.

Plasma glucose monitoring can be used to determine whether adjustments in foods and meals will be sufficient to achieve blood glucose goals or if medication s needs to be combined with MNT. Healthy lifestyle nutrition recommendations for the general public are also appropriate for individuals with type 2 diabetes. Because many individuals with type 2 diabetes are overweight and insulin resistant, MNT should emphasize lifestyle changes that result in reduced energy intake and increased energy expenditure through physical activity.

Because many individuals also have dyslipidemia and hypertension, reducing saturated and trans fatty acids, cholesterol, and sodium is often desirable. Therefore, the first nutrition priority is to encourage individuals with type 2 diabetes to implement lifestyle strategies that will improve glycemia, dyslipidemia, and blood pressure.

Although there are similarities to those above for type 1 diabetes, MNT recommendations for established type 2 diabetes differ in several aspects from both recommendations for type 1 diabetes and the prevention of diabetes. MNT progresses from prevention of overweight and obesity, to improving insulin resistance and preventing or delaying the onset of diabetes, and to contributing to improved metabolic control in those with diabetes.

With established type 2 diabetes treated with fixed doses of insulin or insulin secretagogues, consistency in timing and carbohydrate content of meals is important. In many schools, a Nutrition class will fall within the Family and Consumer Science or Health departments.

In some American schools, students are required to take a certain number of FCS or Health related classes. Nutrition is offered at many schools, and, if it is not a class of its own, nutrition is included in other FCS or Health classes such as: In many Nutrition classes, students learn about the food groups, the food pyramid, Daily Recommended Allowances, calories, vitamins, minerals, malnutrition, physical activity, healthful food choices, portion sizes, and how to live a healthy life.

In the US, Registered dietitian nutritionists RDs or RDNs [89] are health professionals qualified to provide safe, evidence-based dietary advice which includes a review of what is eaten, a thorough review of nutritional health, and a personalized nutritional treatment plan. They also provide preventive and therapeutic programs at work places, schools and similar institutions. Certified Clinical Nutritionists or CCNs, are trained health professionals who also offer dietary advice on the role of nutrition in chronic disease, including possible prevention or remediation by addressing nutritional deficiencies before resorting to drugs.

These Board Certified Nutritionists typically specialize in obesity and chronic disease. In order to become board certified, potential CNS candidate must pass an examination, much like Registered Dieticians.

This exam covers specific domains within the health sphere including; Clinical Intervention and Human Health. The study found that health literacy increases with education and people living below the level of poverty have lower health literacy than those above it. Another study examining the health and nutrition literacy status of residents of the lower Mississippi Delta found that 52 percent of participants had a high likelihood of limited literacy skills.

For example, only 12 percent of study participants identified the My Pyramid graphic two years after it had been launched by the USDA. The study also found significant relationships between nutrition literacy and income level and nutrition literacy and educational attainment [93] further delineating priorities for the region. Among these problems are the lack of information about food choices, a lack of understanding of nutritional information and its application to individual circumstances, limited or difficult access to healthful foods, and a range of cultural influences and socioeconomic constraints such as low levels of education and high levels of poverty that decrease opportunities for healthful eating and living.

The links between low health literacy and poor health outcomes has been widely documented [94] and there is evidence that some interventions to improve health literacy have produced successful results in the primary care setting.

More must be done to further our understanding of nutrition literacy specific interventions in non-primary care settings [93] in order to achieve better health outcomes. Malnutrition refers to insufficient, excessive, or imbalanced consumption of nutrients by an organism. In developed countries, the diseases of malnutrition are most often associated with nutritional imbalances or excessive consumption. In developing countries, malnutrition is more likely to be caused by poor access to a range of nutritious foods or inadequate knowledge.

The aim was to boost nutrition and livelihoods by producing a product that women could make and sell, and which would be accepted by the local community because of its local heritage.

Although under- and over-nutrition are often viewed as human problems, pet animals can be under- or overfed by their owners, domesticated animals can be undernourished for macro- and micro-nutrients, affecting growth and health, and wild animals can be undernourished to the point of starvation and death.

Nutritionism is the view that excessive reliance on food science and the study of nutrition can lead to poor nutrition and to ill health. It was originally credited to Gyorgy Scrinis , [96] and was popularized by Michael Pollan.

Since nutrients are invisible, policy makers rely on nutrition experts to advise on food choices. Because science has an incomplete understanding of how food affects the human body, Pollan argues, nutritionism can be blamed for many of the health problems relating to diet in the Western World today. ULs are set a safe fraction below amounts shown to cause health problems.

ULs are part of Dietary Reference Intakes. When too much of one or more nutrients is present in the diet to the exclusion of the proper amount of other nutrients, the diet is said to be unbalanced. High calorie food ingredients such as vegetable oils, sugar and alcohol are referred to as "empty calories" because they displace from the diet foods that also contain protein, vitamins, minerals and fiber.

Research indicates that improving the awareness of nutritious meal choices and establishing long-term habits of healthy eating have a positive effect on cognitive and spatial memory capacity, with potential to increase a student's ability to process and retain academic information. Some organizations have begun working with teachers, policymakers, and managed foodservice contractors to mandate improved nutritional content and increased nutritional resources in school cafeterias from primary to university level institutions.

Health and nutrition have been proven to have close links with overall educational success. There is limited research available that directly links a student's Grade Point Average G.

Additional substantive data is needed to prove that overall intellectual health is closely linked to a person's diet, rather than just another correlation fallacy. Nutritional supplement treatment may be appropriate for major depression , bipolar disorder , schizophrenia , and obsessive compulsive disorder , the four most common mental disorders in developed countries.

Cancer is now common in developing countries. According to a study by the International Agency for Research on Cancer , "In the developing world, cancers of the liver, stomach and esophagus were more common, often linked to consumption of carcinogenic preserved foods, such as smoked or salted food, and parasitic infections that attack organs. Several lines of evidence indicate lifestyle-induced hyperinsulinemia and reduced insulin function i. For example, hyperinsulinemia and insulin resistance are strongly linked to chronic inflammation, which in turn is strongly linked to a variety of adverse developments such as arterial microtrauma and clot formation i.

Hyperinsulinemia and insulin resistance the so-called metabolic syndrome are characterized by a combination of abdominal obesity , elevated blood sugar , elevated blood pressure , elevated blood triglycerides , and reduced HDL cholesterol. The state of obesity clearly contributes to insulin resistance, which in turn can cause type 2 diabetes.

Virtually all obese and most type 2 diabetic individuals have marked insulin resistance. Although the association between overweight and insulin resistance is clear, the exact likely multifarious causes of insulin resistance remain less clear.

It has been demonstrated that appropriate exercise, more regular food intake, and reducing glycemic load see below all can reverse insulin resistance in overweight individuals and thereby lower their blood sugar level , in those with type 2 diabetes.

In addition, reduced leptin signaling to the brain may reduce leptin's normal effect to maintain an appropriately high metabolic rate. In any case, analogous to the way modern man-made pollution may possess the potential to overwhelm the environment's ability to maintain homeostasis , the recent explosive introduction of high glycemic index and processed foods into the human diet may possess the potential to overwhelm the body's ability to maintain homeostasis and health as evidenced by the metabolic syndrome epidemic.

Antinutrients are natural or synthetic compounds that interfere with the absorption of nutrients. Nutrition studies focus on antinutrients commonly found in food sources and beverages.

The relatively recent increased consumption of sugar has been linked to the rise of some afflictions such as diabetes, obesity, and more recently heart disease. Increased consumption of sugar has been tied to these three, among others. In the same time span that obesity doubled, diabetes numbers quadrupled in America. Increased weight, especially in the form of belly fat, and high sugar intake are also high risk factors for heart disease.

Elevated amounts of Low-density lipoprotein LDL cholesterol, is the primary factor in heart disease. In order to avoid all the dangers of sugar, moderate consumption is paramount. Since the Industrial Revolution some two hundred years ago, the food processing industry has invented many technologies that both help keep foods fresh longer and alter the fresh state of food as they appear in nature.

Cooling is the primary technology used to maintain freshness, whereas many more technologies have been invented to allow foods to last longer without becoming spoiled. These latter technologies include pasteurisation , autoclavation , drying , salting , and separation of various components, all of which appearing to alter the original nutritional contents of food.

Pasteurisation and autoclavation heating techniques have no doubt improved the safety of many common foods, preventing epidemics of bacterial infection. But some of the new food processing technologies have downfalls as well. Modern separation techniques such as milling , centrifugation , and pressing have enabled concentration of particular components of food, yielding flour, oils, juices, and so on, and even separate fatty acids, amino acids, vitamins, and minerals.

Inevitably, such large-scale concentration changes the nutritional content of food, saving certain nutrients while removing others. Heating techniques may also reduce food's content of many heat-labile nutrients such as certain vitamins and phytochemicals, and possibly other yet-to-be-discovered substances. In addition, processed foods often contain potentially harmful substances such as oxidized fats and trans fatty acids. A dramatic example of the effect of food processing on a population's health is the history of epidemics of beri-beri in people subsisting on polished rice.

Removing the outer layer of rice by polishing it removes with it the essential vitamin thiamine , causing beri-beri. Another example is the development of scurvy among infants in the late 19th century in the United States.

It turned out that the vast majority of sufferers were being fed milk that had been heat-treated as suggested by Pasteur to control bacterial disease. Pasteurisation was effective against bacteria, but it destroyed the vitamin C. As mentioned, lifestyle- and obesity-related diseases are becoming increasingly prevalent all around the world. There is little doubt that the increasingly widespread application of some modern food processing technologies has contributed to this development.

The food processing industry is a major part of modern economy, and as such it is influential in political decisions e. In any known profit-driven economy, health considerations are hardly a priority; effective production of cheap foods with a long shelf-life is more the trend. In general, whole, fresh foods have a relatively short shelf-life and are less profitable to produce and sell than are more processed foods. Thus, the consumer is left with the choice between more expensive, but nutritionally superior, whole, fresh foods, and cheap, usually nutritionally inferior, processed foods.

Because processed foods are often cheaper, more convenient in both purchasing, storage, and preparation , and more available, the consumption of nutritionally inferior foods has been increasing throughout the world along with many nutrition-related health complications.
