2 What Is a Grain? A grain is a seed or a fruit of a cereal grass Grains are classified as complex carbohydrates –Complex carbohydrates are chains of glucose, a simple sugar, linked together in long chains –When you eat a complex carbohydrate, enzymes in your intestine break it down into glucose

3 Glucose Fuels the Brain The brain prefers to use glucose for energy When levels of glucose in the blood fall, it can become difficult to concentrate –You may feel weak –You may feel nauseated –You may feel confused

4 Glucose Fuels the Brain In rats, the more cognitive power required for a task, the more brain glucose is depleted Elderly people who drank a glucose drink recalled almost twice as much from a narrative prose passage as those who drank one with saccharin

5 Fuel Your Brain Any carbohydrate can supply the needed glucose for the brain, but foods high in fiber are the best choice because fiber has so many health benefits Low-fat carbohydrates are the best foods for cognitive function –Fat can stall the energizing effects of glucose Whole grains are a great source of low-fat carbohydrates that are also high in fiber

6 Today You Will Learn… The parts of a whole grain What are refined grains? Health benefits of whole grains The truth to this statement: I am trying to lose weight, so I want to watch my carbs. Examples of whole grains

7 Parts of a Whole Grain

8 What Are the Parts of a Whole Grain? 1.Bran 2.Germ 3.Endosperm

9 Bran Outer layers of grain kernel Contains: –Fiber –B Vitamins –Protein –Trace Minerals

10 Endosperm Starchy portion of grain kernel Contains: –Protein –Complex Carbohydrate –Iron –Some B Vitamins

11 Germ Embryo of kernel Contains: –Vitamin E –B Vitamins and Folate –Fiber –Iron, Magnesium, Chromium, Potassium, Manganese, Copper, Selenium –Phytochemical: Phytosterols

12 What are refined grains?

13 What Are Refined Grains? Refined grains are made from the endosperm They have the germ and bran removed Examples: –White flour –White rice

14 What Is a Refined Grain? Removing the germ and bran also removes fiber, vitamins, minerals and phytochemicals This is done by manufacturers to increase palatability and storage life

18 Health Benefits of Whole Grains

19 Whole Grains Have a Health Claim! Contains all portions of the grain kernel Contains 51% whole-grain ingredient(s) or more by weight per reference amount customarily consumed Meets the general requirements for a healthful food – low in fat, etc. Diets rich in whole grain foods and other plant foods and low in total fat, saturated fat, and cholesterol may reduce the risk of heart disease and some cancers. – Food and Drug Administration-allowed health claim

20 Whole Grains: The Base of a Healthy Diet Provide: –Carbohydrates – bodys main source of energy –Fiber –Vitamins, minerals and phytochemicals Naturally low in fat and sodium

21 Whole Grains Benefit Your Health Fiber – –Decreases risk for: Heart Disease Diabetes Cancer –Helps with: Weight Control Digestive Health Whole-grain cereals, fruits and vegetables are the preferred sources of dietary fiber. – Diet, Nutrition and the Prevention of Chronic Diseases, World Health Organization Report, Geneva 2003

22 More Health Benefits of Whole Grains Lower Calorie Density: –Makes you feel full –Decreases hunger –Reduces calories –Aids weight loss Energy-dense and micronutrient-poor foods tend to be processed foods that are high in fat and/or sugars. Low energy-dense foods, such as fruit, legumes, vegetables and whole grain cereals, are high in dietary fiber and water. – WHO Report

23 How Many Whole Grains per Day? Dietary Guidelines for Americans call for at least half of your grain servings to come from whole grains Consuming at least 3 ounce-equivalents of whole grains per day can reduce the risk of coronary heart disease, may help with weight maintenance, and may lower risk for other chronic diseases.. – 2005 Dietary Guidelines for Americans

24 Only 8 percent met the recommendation to eat at least three servings of whole grains per day. Source: Linda E. Cleveland et al,, Dietary Intake of Whole Grains, Journal of the American College of Nutrition, vol. 19, no. 3, 331S-338S (2000)

25 I am trying to lose weight, so I want to watch my carbs. Whether your body weight goes up or down depends on energy balance and not the ratio of fat to carbohydrate to protein in the diet. If you eat excess calories, your body will store some of the fat you eat as body fat. – May 2004 Communicating Food for Health Newsletter

26 Is This True? Many popular diet books claim that carbohydrates are fattening.

27 But…Success from the National Weight Control Registry Says… Thousands who maintain a weight loss of 30 pounds or more for at least a year –Eat a diet that is low in fat and high in carbohydrate –AND they have high levels of physical activity 1 1 Klem ML, Wing RR, McGuire MT, Seagle HM, Hill JO. A descriptive study of individuals successful at long-term maintenance of substantial weight loss. Am J Clin Nutr. 1997;66:

28 Low Carbs Do Not Work Long Term Less than 1% of the participants in the NWCR have used a low- carb diet. 1 With Dr. Atkins book, Dr. Atkins New Diet Revolution (1992, 1999) selling more than 10 million copies worldwide, you would think this number would be much higher. 2 1 Klem ML, Wing RR, McGuire MT, Seagle HM, Hill JO. A descriptive study of individuals successful at long-term maintenance of substantial weigh loss. Am J Clin Nutr. 1997;66:

29 Low Carbs Equal Higher Body Fat An examination of popular diets found: –The Body Mass Indexes (BMI) were significantly lower for men and women on a high-carbohydrate diet –The highest BMIs were noted for those on a low-carbohydrate diet. 1 1 Kennedy ET, Bowman SA, Spence JT, et al.
