    snow Cholestrol

    Definition

    Cholesterol is a soft, waxy substance found in all parts of the body. This includes the nervous system, skin, muscle, liver, intestines, and heart. It is made by the body and also obtained from animal products in the diet.


    Function

    Cholesterol is manufactured in the liver for normal body functions, including the production of hormones, bile acid, and vitamin D. It is transported in the blood to be used by all parts of the body.

    Food Sources

    In foods, cholesterol is found in eggs, dairy products, meat, and poultry. Egg yolks and organ meats (liver, kidney, sweetbread, and brain) are high in cholesterol. Fish generally contains less cholesterol than other meats, but some shellfish are high in cholesterol.

    Foods of plant origin (vegetables, fruits, grains, cereals, nuts, and seeds) contain no cholesterol.

    Fat content is not a good measure of cholesterol content. For example, liver and other organ meats are low in fat, but very high in cholesterol.

    Side Effects


    In general, you have a greater risk of developing heart disease or atherosclerosis as your level of blood cholesterol increases.

    Recommendations

    More than half of the adult population has blood cholesterol levels higher than the desirable range. High cholesterol levels often begin in childhood. Some children may be at higher risk due to a family history of high cholesterol.

    In general, you want your total cholesterol to be less than 200 milligrams per deciliter (mg/dl), because that level carries the least risk of heart disease. When the level is above 200 mg/dl, the risk for heart disease increases.

    You should also know your levels of high density lipoprotein (HDL, also known as the "good cholesterol") and low density lipoprotein (LDL, or "bad cholesterol"). Talk to your health care provider about what your cholesterol levels mean.

    To lower high cholesterol levels:

    Limit total fat intake to 25 - 35% of total daily calories. Less than 7% of daily calories should be from saturated fat, not more than 10% should be from polyunsaturated fat, and not more than 20% from monounsaturated fat.
    Eat less than 200 mg of dietary cholesterol per day.
    Get more fiber in your diet.
    Lose weight.
    Increase physical activity.
    The recommendations for children's diets are similar to those of adults. It is very important that children get enough calories to support their growth and activity level, and that the child achieve and maintain a desirable body weight

    The following two sample menus provide examples of an average American diet and a low-fat diet.

    AVERAGE AMERICAN DIET

    Breakfast
    1 egg scrambled in 1 teaspoon of butter
    2 slices of white toast
    1 teaspoon of butter
    1/2 cup of apple juice
    Snack
    1 cake donut
    Lunch
    1 ham and cheese sandwich (2 ounces of meat, 1 ounce of cheese)
    white bread
    1 teaspoon of mayonnaise
    1-ounce bag potato chips
    12-ounce soft drink
    2 chocolate chip cookies
    Snack
    8 wheat thins
    Dinner
    3 ounces of broiled sirloin
    1 medium baked potato
    1 tablespoon of sour cream
    1 teaspoon of butter
    1/2 cup of peas, 1/2 teaspoon of butter
    Totals: 2,000 Calories, 84 grams fat, 34 grams saturated fat, 425 milligrams cholesterol. The diet is 38% total fat, 15% saturated fat.

    LOW FAT DIET


    Breakfast
    1 cup of toasted oat ring cereal
    1 cup of skim milk
    1 slice of whole-wheat bread
    1 banana
    Snack
    1 cinnamon raisin bagel, 1/2 ounce light cream cheese
    Lunch
    turkey sandwich (3 ounces of turkey)
    rye bread
    lettuce
    1 orange
    3 fig newtons
    1 cup skim milk
    Snack
    non fat yogurt with fruit
    Dinner
    3 ounces of broiled chicken breast
    1 medium baked potato
    1 tablespoon of nonfat yogurt
    1/2 cup of broccoli
    1 dinner roll
    1 cup skim milk
    Totals: 2,000 Calories, 38g fat, 9.5g saturated fat, 91mg cholesterol. The diet is 17% fat, 4% saturated fat.

    COMPARISON

    For the same number of calories, a low-fat diet provides 190 mg of cholesterol, compared to 510 mg of cholesterol for an average American diet.

    Because fat is high in calories, the low-fat diet actually has more food than the typical American diet.

    CHILDREN

    The low-fat diet example is too low in fat for small children to promote good growth. In addition, it may be difficult for them to consume such a large volume of food. Children should have a diet that is closer to 30% of calories from fat. Lower-fat diets may be appropriate in some children. Ask your doctor what is best for your child.
