- FUNCTION-
-
- The majority of the choles-
- terol in our body is made by
- the liver, whether we eat any
- or not. This "serum choles-
- terol" has been found as an
- indicator of heart attack risk.
- This cholesterol circulates in
- the bloodstream and can
- accumulate on the walls of
- blood vessels. Researchers
- believe only 20 or 30 percent
- of the population is sensitive
- to dietary cholesterol, which
- can increase the levels of
- "serum cholesterol". Unfor-
- tunately, there is no easy test
- to determine if a person is
- genetically hypersensitive to
- dietary cholesterol. Some
- cholesterol is necessary as a
- vital component of cell mem-
- branes and nerves, and
- important in the building of
- specific hormones.

-
- FOOD SOURCES-
-
- Dietary cholesterol comes
- only from animal products:
- meats, fish, poultry, eggs
- and dairy. Cholesterol is not
- found in plant sources: fruits,
- vegetables, grains, nuts,
- beans, or legumes.
-
-
- RISKS WITH EXCESS-
-
- FDA says a diet high in satu-
- rated fat and cholesterol has
- been linked to a greater risk
- of coronary heart disease.
- Therefore, it is recommended
- that all Americans limit their
- dietary cholesterol to no more
- than 300 milligrams per day.
- The risks associated with a
- high cholesterol diet are in-
- creased when combined with
- other risk factors, such as
- smoking, hypertension, dia-
- betes, obesity, and a family
- history of heart disease.
-
-
- RISKS WITH DEFICIENCY-
-
- Cholesterol is not an essen-
- tial nutrient for humans. All
- the cholesterol the body
- needs is produced by the
- liver. There is no risk with a
- diet below 300 milligrams of
- cholesterol per day.
