Meat on a low fat diet
Report #6413 1/26/95
 
If you're trying to lower a high cholesterol, you have to restrict your intake of meat, 
fish and chicken.

Having a high cholesterol markedly increases your chances of developing a heart attack. 
Saturated fat raises cholesterol more than any other component in food. However, it 
does this only when you take in more calories than you burn. If you burn all the 
calories you take in, there is none left over to raise cholesterol. 

A lot of people eat chicken and fish because they think that it will lower cholesterol. 
However, substituting chicken for beef does not lower cholesterol and substituting beef 
for chicken does not raise it. The same applies to fish. Even though meat contains more 
saturated fat than chicken and fish do, much of the extra saturated fat in meat comes 
from stearic acid which does not raise cholesterol much. For example, chocolate is also 
loaded with saturated fat but it does not raise cholesterol much because most of its 
saturated fat is stearic acid. If you want a diet to lower cholesterol or lose weight, 
you have to eat lots of fruits, vegetables, whole grains and beans and limit your intake 
of meat, fish and chicken. It makes sense to eat fish two or three times a week, because 
it helps to prevent clotting, the last event in a heart attack. However, there is no 
extra anticlotting benefit from eating fish more than three times a week or taking fish 
oil pills.

cholesterol-lowering diet. American Journal of Clinical Nutrition 60: 6 Suppl.;
(DEC 1994):S1044-S1049. Because beef fat is 19% stearic acid, the cholesterol-raising 
potential of beef is not as great as predicted by its total saturated fatty acid content. 
Therefore, curtailment of beef tallow in a cholesterol lowering diet seems appropriate. 
Data suggest that lean beef is no more hypercholesterolemic than chicken or fish.

evaluating the plasma lipid effects of stearic acid. American Journal of Clinical 
Nutrition 60: 6 Suppl.;DEC 1994:S1029-S1036. Milk chocolate does not adversely affect 
plasma lipids and lipoproteins despite its relatively high content of saturated fatty 
acids (SFAs). Evidence from well-controlled feeding studies indicates that this unique 
response is due to the high proportion of stearic acid in milk chocolate.

chocolate bar per day substituted for a high-carbohydrate snack in young men on an 
NCEP/AHA Step 1 Diet. American Journal of Clinical Nutrition 60: 6 Suppl.;
DEC 1994:S1037 S1042. Substitution of a milk chocolate bar for a high-carbohydrate 
snack did not adversely affect the low-density- lipoprotein-(LDL) cholesterol 
response to a Step 1 Diet despite an increase in total fat and saturated fatty acid 
content of the diet. This response may be due to stearic acid.
