6What to Know About Diet and Cancer
- Diets high in antioxidants have been associated
with decreased rates of esophagus, lung, colon,
and stomach cancer.
- An antioxidant is a substance that protects cells
from being damaged by oxidation.
- Their actions help prevent healthy cells from
becoming cancerous cells. - Vitamins C, E, and A, and the mineral selenium
are antioxidants.
7What to Know About Diet and Cancer
Tips to Reduce the Risk of Cancer
Avoid obesity. Being obese increases the risk of
developing cancers of the uterus, breast,
gallbladder, prostate gland, and colon.
Eat several servings and a variety of fruits,
vegetables, and fiber-rich foods each day.
Especially eat cruciferous vegetables, such as
cauliflower, broccoli, and brussels sprouts.
Fruits and vegetables provide antioxidants, and
fiber-rich foods reduce the risk of cancers of
the colon and rectum.
8What to Know About Diet and Cancer
Tips to Reduce the Risk of Cancer
Limit fat intake and the consumption of foods
that are smoked, salted, or nitrate cured.
Limiting the amount of fat you eat helps reduce
the risk of developing cancers of the breast,
prostate gland, and colon.
Do not drink alcohol as a teen. Alcohol
consumption robs the body of vitamins needed for
optimal health.
9Diet and Cardiovascular Disease
- Cardiovascular disease is a disease of the heart
and blood vessels.
- Cardiovascular diseases are a leading cause of
premature death and disability.
10What to Know About Cardiovascular Disease
- Limit fat and cholesterol intake.
- Cholesterol is a fatlike substance made by the
body and found in some foods. - Eating foods that are high in saturated fats and
cholesterol may cause plaque to form on artery
walls. - Atherosclerosis is a disease in which plaque
deposits on artery walls.
11What to Know About Cardiovascular Disease
- An embolism is the blockage of an artery by a
clump of material traveling in the bloodstream.
- If the blockage is in an artery in the brain, a
person could have a stroke. - If the blockage is in an artery in the heart, a
heart attack could occur. - A blockage in the lung is called a pulmonary
embolism.
12What to Know About Cardiovascular Disease
How to Limit Fat Intake Less than 30 of total
calories per day should come from fat. Limit
your intake of cooked lean meat, poultry, and
fish to 5 ½ oz per day. Broil, bake, or steam
food rather than fry it. Trim fat from meats
before cooking. Trim fat from poultry before
cooking. Limit your intake of egg yolks
consider using egg substitutes.

high-fat desserts. Substitute turkey, such as
turkey hot dogs and turkey chili, for red meat.
14What to Know About Cardiovascular Disease
How to Limit Fat Intake Less than 30 of total
calories per day should come from fat.
Substitute nonfat or low-fat dairy products for
whole-milk dairy products, such as low-fat yogurt
for ice cream, skim milk for whole milk,
reduced-fat mayonnaise for regular mayonnaise,
low-fat or nonfat cheese for regular cheese.
Substitute fruits and vegetables for high-fat
snacks, such as potato chips.
15What to Know About Cardiovascular Disease
- Increase your intake of foods and beverages
containing antioxidants.
- Antioxidants help prevent wear and tear in blood
vessels.
16What to Know About Cardiovascular Disease
- Limit your intake of sodium.
- Sodium is a mineral your body needs only in small
amounts. The recommended daily allowance of
sodium is three grams. - Too much sodium may cause some people to retain
body fluid and, as a result, have increased blood
pressure. - You can limit your sodium intake by eating fresh
foods rather than canned foods.
17What to Know About Cardiovascular Disease
- Include flax, soy, canola, olive, and fish oils
in your diet.
- The unsaturated fats in these foods can help
- prevent heart disease,
- lower bad cholesterol (LDL),
- and increase good cholesterol (HDL).
18What to Know About Cardiovascular Disease
A 2002 Nurses Health Study found an inverse
relationship between fish consumption, omega-3
fatty acids, and coronary heart disease (CHD).
The more fish women ate, the lower their risk of
CHD was. The percentages on the graph represent
reduced risk.
19Diet and Osteoporosis
- Osteoporosis is a disease characterized by low
bone mass and deterioration of bone tissue.
- Osteoporosis causes bones to fracture easily, and
is a major cause of disability in females. - Females are 10x more likely to have severe
osteoporosis than are males.
20What to Know About Diet and Osteoporosis
- Calcium and phosphorus form the hard substance in
bone.
- Calcium is a mineral that is essential to bone
growth. - A deficiency of calcium, especially in females,
increases the risk for osteoporosis. - Obtaining enough calcium during adolescence is
critical to reduce the risk of osteoporosis.
21What to Know About Diet and Osteoporosis
- Other ways to avoid osteoporosis
- Other ways to help prevent osteoporosis include
- Engage in weight-bearing exercise.
- Avoid smoking.
- Utilize bone density testing and medications when
appropriate.
22What to Know About Diet and Osteoporosis
- In both men and women, bone mass usually peaks
between the ages of 25 and 35. - For women, an average bone loss before menopause
is 11.25 per year, but it increases to 34
after menopause.
23What to Know About Diet and Osteoporosis
- Heart disease and hormonal replacement
- A womans estrogen production is reduced when she
reaches menopause thus, the body cannot use
calcium effectively and the result is an
increased risk of osteoporosis. - Recent studies claim that hormonal replacement
therapy increases the risk for heart disease,
stroke, and cancer in women.
24Diet, Diabetes, and Hypoglycemia
- Diabetes mellitus, or diabetes, is a disease in
which the body produces little or no insulin, or
cannot properly use insulin.
- Insulin is a hormone that regulates the blood
sugar level. - Without treatment, a person with diabetes will
have a high blood sugar level.
25What to Know About Diet, Diabetes, and
Hypoglycemia
- A physician and a dietitian can work with someone
who has diabetes to make a plan that may include
- Eating more complex carbohydrates and protein
- Limiting simple carbohydrate intake
- Eating six small meals a day
- Having regular exams to test blood sugar levels
and re-evaluate diet - Maintaining desirable weight
26What to Know About Diet, Diabetes, and
Hypoglycemia
- A lack of physical activity and obesity greatly
increase the risk for diabetes. - Early signs of diabetes include
- frequent urination,
- excessive thirst,
- cravings for sweets,
- and weakness.
27What to Know About Diet, Diabetes, and
Hypoglycemia
- Hypoglycemia is a condition in which there is too
much insulin in the body, causing the blood sugar
level to be low.
- People with hypoglycemia experience a rapid
increase in blood sugar when eating, followed by
a sudden drop. - When their blood sugar level drops, they feel
dizzy, weak, irritable, and confused.
28What to Know About Diet, Diabetes, and
Hypoglycemia
Guidelines for People with Hypoglycemia People
with hypoglycemia follow a diet similar to people
who have diabetes and may follow the same
guidelines
Eat complex carbohydrates and protein to
provide long-lasting energy. Limit the amounts
of sweets. Simple sugars increase blood sugar and
the need for insulin.
Eat six small meals a day to maintain a
constant blood sugar level. Have regular
examinations to test blood sugar levels and
re-evaluate diet. Maintain a desirable weight.
29Food Allergies and Intolerances
- A food allergy is an abnormal response to food
that is triggered by the immune system.
- Food allergies can cause severe illness or even
death.
30What to Know About Food Allergies and Intolerances
- The most common foods that cause allergic
reactions in adults are shellfish, peanuts, fish,
and eggs. - Symptoms of food allergies include diarrhea,
swelling, sneezing, itching, and nausea.
31What to Know About Food Allergies and Intolerances
- A food intolerance is an abnormal response to
food that is not caused by the immune system.
- This merely means that a food is not tolerated
well.
32What to Know About Food Allergies and Intolerances
- Lactase deficiency is a condition in which
lactase, an enzyme that breaks down the milk
sugar present in the cells of the small
intestine, is missing.
- This condition results in the inability to digest
lactose and is called lactose intolerance.
33What to Know About Food Allergies and Intolerances
- Celiac disease is a condition in which a person

- Gluten is a part of wheat, rye, barley, and
certain other grains.
34What to Know About Food Allergies and Intolerances
- Monosodium glutamate (MSG), a flavor enhancer
added to many foods, is a common cause of food
intolerance. - Sulfites added to foods also may cause food
intolerance.
