Canada's Food Guide to Healthy Eating
and the American Heart Association Eating Plan suggest that you eat
foods that are high in soluble and insoluble
fibre. Foods that are high in soluble fibre, including
oat bran, oatmeal, beans, peas, rice bran, barley, citrus fruits, strawberries,
and apple pulp, have been shown to reduce blood cholesterol. It is recommended
that people eat 20 to 35 grams of soluble and insoluble fibre per day.
The greatest cholesterol-lowering effect of soluble fibre occurs in
people who have
high cholesterol levels. One
study found that dietary fibre intake from 25 to 30 grams lowered the risk of
coronary artery disease (CAD) by 12% in U.S. men and
women.1
Insoluble fibre doesn't seem to affect blood cholesterol, but it
promotes healthy bowel movement. Foods that are high in insoluble fibre include
whole wheat breads, wheat cereals, wheat bran, cabbage, beets, carrots,
Brussels sprouts, turnips, cauliflower, and apple skin. Fibre from such foods
is better for the bowel than fibre supplements, such as psyllium seed products.
However, psyllium (a common ingredient in non-prescription fibre
supplements and laxatives) has been used to boost the effectiveness of some
lipid-lowering drugs while reducing the stomach upset
commonly caused by those drugs.2
These products are not recommended to replace foods as a source of
fibre.
Psyllium may significantly reduce cholesterol in people who are
already eating a low-fat diet.3
