HEALTHY
HEARTS
The goals of a heart-healthy diet are to eat foods that
help obtain or maintain healthy levels of cholesterol and fatty molecules
called lipids. You can achieve this by: Reducing overall cholesterol levels and
low-density lipoproteins (LDL), which are harmful to the heart Increasing
high-density lipoproteins (HDL), which are beneficial for the heart Reducing
other harmful lipids (fatty molecules), such as triglycerides and
lipoprotein(a) Any diet should also help keep blood pressure and weight under
control.
General Recommendation
Of The American Heart Associationss
The current dietary and lifestyle
guidelines recommend: Balance calorie intake and physical activity to achieve
or maintain a healthy body weight. (Controlling weight, quitting smoking, and
exercising regularly are essential companions of any diet program. Try to get
at least 30 minutes, and preferably 60 - 90 minutes, of daily exercise.) Eat a
diet rich in a variety of vegetables and fruits. Vegetables and fruits that are
deeply colored (such as spinach, carrots, peaches, and berries) are especially
recommended as they have the highest micronutrient content.
Choose whole-grain, high-fiber foods. These include fruits,
vegetables, and legumes (beans). Good whole grain choices include whole wheat,
oats/oatmeal, rye, barley, brown rice, buckwheat, bulgur, millet, and quinoa.
Eat fish, especially oily fish, at least twice a week (about 8 ounces/week).
Oily fish such as salmon, mackerel, and sardines are rich in the omega-3 fatty
acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA).
Consumption of these fatty acids is linked to reduced risk
of sudden death and death from coronary artery disease. Get at least 5 - 10% of
daily calories from omega-6 fatty acids, which are found in vegetable oils such
as sunflower, safflower, corn, and soybean as well as nuts and seeds. Limit
daily intake of saturated fat (found mostly in animal products) to less than 7%
of total calories, trans fat (found in hydrogenated fats, commercially baked
products, and many fast foods) to less than 1% of total calories, and
cholesterol (found in eggs, dairy products, meat, poultry, fish, shellfish) to
less than 300 mg per day.
Choose lean meats and vegetable alternatives (such as soy).
Select fat-free and low-fat dairy products. Grill, bake, or broil fish, meat,
and skinless poultry. Use little or no salt in your foods. Reduce or avoid
processed foods that are high in sodium (salt). Reducing salt can lower blood
pressure and decrease the risk of heart disease and heart failure. Cut down on
beverages and foods that contain added sugars (corn syrups, sucrose, glucose,
fructose, maltrose, dextrose, concentrated fruit juice, honey). If you consume
alcohol, do so in moderation.
The AHA recommends limiting alcohol to no more than 2 drinks
per day for men and 1 drink per day for women. People with existing heart
disease should consider taking omega-3 fatty acid supplements (850 - 1,000
mg/day of EPA and DHA). For people with high triglyceride levels, higher doses
(2 - 4 g/day) may be appropriate. The AHA recommends against taking antioxidant
vitamin supplements (C, E, beta-carotene) or folic acid supplements for
prevention of heart disease. Women Women who are pregnant or breastfeeding
should avoid eating fish that is high in mercury content (shark, swordfish,
mackerel, and tile fish). Choose fish and shellfish that are lower in mercury
content and eat about 12 ounces/week. The AHA recommends a higher weekly fish
amount for women than for men. However, women of childbearing age should limit
tuna to 6 ounces a week to reduce the risks for mercury contamination.
Children Atherosclerosis, the
build-up of plaque in the arteries, begins in childhood. It is important for
children and adolescents to adopt a heart-healthy diet to help prevent the
development of heart disease later in life. Children should eat foods that are
low in saturated fat, trans fat, and cholesterol. These foods include: Fruits
and vegetables Whole grains Low-fat and nonfat dairy products Beans, fish, and
lean meats Cholesterol is a soft, waxy substance that is present in parts of
the body, including the nervous system, skin, muscle, liver, intestines, and
heart. It is made by the body and obtained from animal products in the diet.
Cholesterol is manufactured in the liver and is needed for
normal body functions, including the production of hormones, bile acid, and
vitamin D. Excessive cholesterol in the blood contributes to atherosclerosis
and subsequent heart disease. The risk of developing heart disease or
atherosclerosis increases as the level of blood cholesterol increases.
