MARGARINE:LEADING SOURCE OF FAT IN US
Report #6203 5/25/94


Eating too much fat makes you fat and raises your cholesterol.
Margarine is the leading source of fat in the American diet.
Some people still foolishly think that eating extra margarine
helps to prevent heart attacks.

Because eating large amounts of animal fats are associated with
heart attacks and certain cancers, manufacturers try to make their
bakery and cereal products from vegetable oils and Americans used
to be encouraged to substitute margarine for butters. However, the
unsaturated fats in vegetable oils have a relatively short shelf
life, so manufacturers found that they could make the products
last longer by converting the unsaturated fats in vegetable oils
into partially hydrogenated trans fats. Many Americans felt that
they could prevent heart attacks by using partially hydrogenated
vegetable oils in their bakery and snack products/ and substituting
stick margarine for butter. However, the partially hydrogenated
fats that were placed in foods to substitute for saturated animals
fats now appear to cause heart attacks and cancers.

Drs Walter Willett and Albert Ascherio of Harvard Medical School
feel that at least 30,000 extra deaths due to heart attacks may
come from eating these partially hydrogenated trans fats. Indeed,
another study from Harvard shows that heart attack sufferers take
in significantly more margarine and other sources of trans fats.
Partially hydrogenated fats raise blood levels of the bad LDL
cholesterol and lower levels of the good HDL cholesterol. The
Harvard doctors recommend a phaseout or strict limitation of
partially hydrogenated fats in the United States diet.
