WASHINGTON, Oct. 31 /PRNewswire/ -- A Harvard Medical School publication
recommends soy oils to replace "bad" saturated fats and trans-fats with
healthier "good" omega-6 and omega-3 fatty acids.
The November issue of Harvard Women's Health Watch reports on new
guidelines for healthy eating issued recently by the Institute of Medicine
(IOM), the medical branch of the National Academy of Sciences and the
government's advisory on health policy.
The fats the IOM report advised for replacement by soy oils are saturated
fats, which come from meats and dairy products, for example, and trans-fats
which are found in many commercially baked goods and snacks.
"The IOM report advises replacing these fats with 'good' ones" such as soy
oils which can help lower cholesterol and cardiovascular risk, the Harvard
New guidelines establish for the first time recommended levels of two
types of polyunsaturated fatty acids, alphalinolenic acid, an omega-3 fatty
acid, and linoleic acid, an omega-6 fatty acid.
"The body needs both, but can't make them, so they must come from food,"
the Harvard Women's Health Watch said.
The new guidelines advise women to get 12 grams daily of omega-6 fatty
acids, found in soybean and other oils and in nuts and seeds, and 1.1 grams a
day of omega-3 fatty acids. Soybean and canola oils are good sources of
omega-3s, the Harvard publication said, along with cold-water fish such as
salmon, tuna and swordfish.
