Chapter 11 ObjectivesAfter reading this chapter, you will be able to: Explain the purpose of the government published Dietary Guidelines. List the six major nutrients and describe their main function in the body. Identify the percentages of calories recommended in the diet for carbohydrates,

proteins, and fats. Identify the health benefits of fiber and list good food sources of fiber. Differentiate between complex and simple carbohydrates. Identify the correct descriptions of cholesterol, saturated fats, monounsaturated

fats, polyunsaturated fats, and transfats. Calculate fat grams allowances for specific daily calorie intakes. Describe the role phytochemicals and antioxidants play in nutritional health, and

identify foods high in these compounds. Identify four preventive factors relating to osteoporosis. Describe the USDA’s My Pyramid Food Guide System. Give 10 specific examples of small changes that can be incorporated in to daily

food selections and preparations that could make a significant change in your nutritional wellness.

Look at the food label and identify the largest ingredient; calculate the percentage of calories that come from fat, carbohydrate, and protein; identify the sources of fat (including saturated fat); and identify the sources of complex and simple carbohydrates.

Identify three ways to eat nutritiously in a fast-food restaurant.


Shortfalls in Eating Habits

Poor diet is said to contribute to four of the top ten leading causes of death in our country. There are five shortfalls in our eating habits:– Too few fruits and vegetables– Too little fiber– Too much saturated fat– Too many refined sugars– Too much food overall

Nutrition Basics Six major nutrients: carbohydrates,

protein, fats, vitamins, minerals, and water These nutrients fulfill three main functions

in the body: Provide energy, build and repair tissues, regulate body processes.

Humans should eat a variety of foods Food is associated with every dimension

of wellness


Carbohydrates Main source of energy – stored as glycogen. 45-65% of calories. 4 calories per gram. Focus on complex (starches) versus simple (sugar)

carbs. Complex carbs (potatoes, rice, whole grains, bean

vegetables, etc.) should make up 35–55% of daily calories.

Simple carbs (soft drinks, cakes, cookies, ice cream, candy, etc.) should make up less than 10% of daily calories.

Avoid adding extra fat or sugar to carbohydrates. Fiber is necessary for a healthy diet (lowers bad

cholesterol, keeps you regular, may protect against cancers, nutrient dense).


A Fiber Profile

Glycemic Index (GI)

A scale that measures the extent to which food affects blood glucose levels.

Foods that quickly raise blood glucose are high GI (usually simple sugars).

Low GI foods can help reduce the chance of Type 2 diabetes.

Comprehensive list of glycemic index in food www.glycemicindex.com


Protein Builds and repairs tissues, maintains chemical

balance, and regulates formation of hormones, antibodies, and enzymes. Not an efficient form of energy.

10-35% of daily calories. 4 calories per gram. Avoid excessive protein – linked to kidney disease and

several cancers. Complete proteins have all amino acids and are

usually found in animal sources versus incomplete proteins that do not have all amino acids. People who do not eat animal products must combine foods appropriately to assure proper function of proteins.

Avoid high fat proteins and adding extra fat to proteins!


Fats Provide stored energy and fat-soluble vitamins, needed

for growth and healthy skin and hormone regulation. 20-30% of calories (no more than 10% saturated). 9 calories per gram. Fat burned in the absence of carbs produces ketone

bodies. Build up of poisonous ketone is ketosis – kidney stress, fatigue, nerve damage.

Fish oils – omega 3 fatty acids can inhibit atherosclerosis in coronary arteries and can reduce blood cholesterol levels. Recommended to eat fish twice a week or get from plant sources.


Fats Saturated fats have primarily animal origin and have a

strong link to heart disease and stroke. Polyunsaturated fats come mostly from plant foods and

are a healthier fat to consume. Monounsaturated fats also come from plants and can

decrease total cholesterol and increase HDL cholesterol (the good cholesterol).

Transfats (the result of hydrogenation of unsaturated fats) are more harmful than saturated fats, e.g., margarine, crackers, cookies, doughnuts, pies, French fries, chips, cake, candy, etc.

Cholesterol is a waxy substance found in animal tissue and manufactured in the liver. A diet high in cholesterol has been linked to heart disease. Consume no more than 300 mg of dietary cholesterol. Remember, plants do not have cholesterol.


Figuring Food Percentages

Number of grams multiplied by calories per gram divided by total calories.

10 grams of fat, 200 total calories 10 grams x 9 calories per gram = 90 90/200 total calories = 45% of calories from fat

Grams of fat per day based on desired percentage 20% of calories from fat and 2000 calories 2000 total calories X .2 = 400 calories from fat 400/9 calories per gram = 44.4 grams of fat per day


Vitamins Vitamins are necessary for metabolic function. A,D,E, and K are fat soluble and B and C are

water soluble. Best place to get vitamins is from food. A complex vitamin tablet (plus calcium and iron for

women) is acceptable. Anyone with irregular diet patterns, on weight-reduction regimens, pregnant or lactating women, strict vegetarians, and elderly people should consider other nutritional supplements (ask healthcare provider)


Minerals Critical to enzyme function in the body. Macro

(needed in large doses) and trace minerals (much smaller amounts needed).

Calcium – Most abundant mineral.– Inadequate amounts contribute to osteopenia or

osteoporosis. Iron

– Inadequate iron can be a problem especially among women, teenagers and athletes.

– Contribute to anemia (low iron). – Avoid too much iron – heart disease.

Sodium – High levels can have an effect on blood pressure and

bone density.– Limit intake to 1,500 mg per day.


Water Most important nutrient. Involved in every function of the body. 2/3 of your body weight. Dehydration can result in fatigue, stress,

headaches, constipation, and hunger. Drink an adequate amount of plain water. Are you drinking enough water? If so, your

urine is a clear color. Stay hydrated during exercise! Check out

Chapter 7 for more information on water consumption.


Phytochemicals and Antioxidants Phytochemicals are plant chemicals present in

fruits, vegetables, grains, legumes and seeds. Associated with prevention and treatment of cancer,

cardiovascular diseases, diabetes, and hypertension.

Antioxidants are compounds that neutralize free radical chemical reactions that contribute to atherosclerosis, arthritis, cancer, cataracts, heart disease, stroke and other degenerative diseases.

Antioxidants (phytochemicals, carotenoids, vitamins C and E) suppress cell deterioration and decrease the aging process.


Balanced Diet Eat a variety of foods – concentrate on fruits and veggies

(at least 5 to 9 servings a day), whole grains, and lean proteins. Eat nutrient-dense foods.

Eat appropriate amount of calories – do not starve yourself! Limit sugar, alcohol, and fatty foods and increase fruit and

vegetable intake. Buy healthy foods – at

home and in restaurants. Select food with high nutritional density.

Enjoy food but don’t use it to feel good.

USDA’s MyPyramid

U.S. Department of Agriculture developed MyPyramid to replace the old food guide pyramid.

Multicolored strips run from the bottom of the pyramid up to its apex that represent the spectrum of food choices with width of each strip approximating the quantity of food each of us should consume from each group.

By showing a person climbing the steps at the side of the new pyramid, physical activity is emphasized.

MyPyramid is 12 different pyramids. Visit www.MyPyramid.gov to enter your personal data

and view your own customized pyramid.


Tips for Nutritional Wellness Use fresh, unprocessed foods. Remove the skin from poultry. Eat low-fat dairy products. Eat fish twice a week. Use small amounts of meat in meals and/or eat a meatless meal. Steam, bake, broil or roast foods. Select oils made with unsaturated fats. Use nonstick vegetable oils spray or small amount of olive oil for sautéing. Use deli luncheon meats such as shaved chicken breast and turkey

instead of bologna, salami, or hot dogs. Use applesauce in place of oil when baking. Use plain low-fat yogurt as a substitute for sour cream. Use lettuce leaves as “wraps” rather then breads. Substitute ground turkey for ground beef. Eliminate half the yolks when making scrambled eggs or when baking.

Two egg whites equal one egg in a recipe. Decrease by half the margarine or butter called for in recipes. Use breads and cereals that list whole wheat as the first ingredient. Substitute fruit for syrup. Top foods with vegetables instead of meats, e.g., in pizza, potatoes,

burritos.


Reading Labels Check serving size Watch for hidden sugars Check fat content Avoid coconut and palm oils which are more saturated than

beef fat. Select whole wheat bread – all whole wheat bread is brown

but not all brown bread is whole wheat Check sodium, and other vitamins Figure percentages Balance for the whole day – not the meal or the individual

food Pay attention – your nutrition is your responsibility!


How to Read a Food Label





Eating Out Americans spend more money in restaurants than in grocery

stores. Many fast-food and sit down restaurants have healthy food

selections, but you must choose them! Choose baked over fried. Avoid high fat condiments, such as mayonnaise, sour cream,

gravy, salad dressing, etc. Choose low fat condiments, such as ketchup, non-fat sour cream

and salad dressing, etc. Ask for condiments on the side so you can use sparingly. Avoid mayo-based salads and fatty extras on salads (cheese,

seeds, etc.) Choose baked potatoes, salads, vegetables or soups as a meal. Watch portion sizes – no need to super size. Take home

leftovers or split a meal with a friend. Avoid or limit your portion of high fat, sometimes “free,” additions

such as chips, high fat rolls, and other appetizers.


Special Nutritional Considerations Vegetarian diet – can be very healthy but careful planning

and food selection are important to avoid nutritional deficiencies.

Pregnancy – good nutritional habits (and folic acid intake) before and during pregnancy can improve infant weight and reduce mortality.

Aging – although energy needs tend to drop – nutritional needs don’t. Make calories count by eating nutritionally dense foods.

Sports and Fitness – key to performance is a balanced diet with a wide variety of healthy foods and plenty of fluids.


Rx for Action Eat a whole-grain cereal for breakfast and top

it with fruit. Substitute skim milk, water, or 100 percent

fruit juice for a sweetened soft drink. Make sure your dinner plate has two

different-colored vegetables on it. Try an all-veggie pizza, burrito, wrap, or

sandwich. Choose fruit for dessert or for a snack.
