DIETARY FIBER/BLOOD PRESSURE
High-fiber diets have been shown to be effective in lowering blood
pressure. A group of patients with high blood pressure were given
7 grams of additional fiber per day over a three-month period. They
showed reductions in both diastolic and systolic blood pressure
levels, and lower cholesterol levels. (The Lancet 2:622-623,
September 12, 1987) Copyright Phylis Austin
FIBER INTAKE/HEART DISEASE
A California study suggests that a high intake of dietary fiber may
protect against ischemic heart disease. The chief sources of fiber
in the U.S. diet are vegetables, fruits, and cereals. Earlier
studies have shown that fiber reduces cholesterol, high blood
pressure, and diabetes, all of which are risk factors for heart
disease. (American Journal of Epidemiology 126:1093-1102, 1987) Copyright Phylis Austin
FIBER/BREAST CANCER
A diet high in fiber and low in fats may decrease the risk of
breast cancer. Laboratory rats given high-fiber diets developed
fewer breast tumors than similar animals given little or no fiber.
The researchers observed that doubling the amount of fiber in the
typical Western diet would significantly reduce breast tumors in
the laboratory animals. (Journal of the National Cancer Institute

FRUIT FIBER/HIGH BLOOD PRESSURE
The fiber found naturally in fruit may help in the prevention of
high blood pressure. A study at Harvard revealed that men who ate
an ounce of fiber per day in the form of fruits and vegetables were
less likely to develop high blood pressure (Medical Tribune

HIGH FIBER DIETS/BREAST CANCER
A high-fiber diet may protect from the development of breast cancer
according to a recent study from Australia. The use of whole grain
breads, bran-based breakfast cereals, peas, beans and soybeans,
dried fruits and nuts are all good sources of dietary fiber.

FIBER/HEART DISEASE
High levels of fiber intake from cereals, fruits and vegetables decrease the risk of coronary
heart disease in men. Cereal fiber seemed to be the most effective. (Journal of the

FIBER/HEART ATTACKS
A high-fiber diet may reduce the risk of myocardial infarction (heart attack) according to
a recent study of over 21,000 men. The consumption of each additional 10 grams of fiber
per day reduced the risk of death from heart attack by 17 percent.
The researchers speculate that fiber may function as an anticoagulant.
The American Heart Association recommends the consumption of 25 to 30 grams of fiber
per day, but the typical United States male consumes about 17 grams per day. (Circulation

FIBER INTAKE/BREAST CANCER
A combination of soluble and insoluble fiber intake may be more effective in reducing the
risk of breast cancer than the use of just one type of fiber. A wide variety of high fiber
foods will provide both types of fiber. (Journal of the National Cancer Institute 88(13)899-
907, July 3, 1996) Soluble fiber is digested; insoluble fiber passes through the body without
being digested. Copyright Phylis Austin
