Eat to Live 71
Scientific studies provide evidence that animal protein's effect on
blood cholesterol may be significant. This is one of the reasons those
switching to a low-fat diet do not experience the cholesterol lower-
ing they expect unless they also remove the low-fat animal products
as well. Surprising to most people is that yes, even low-fat dairy and
skinless white-meat chicken raise cholesterol. 1 see this regularly in
my practice. Many individuals do not see the dramatic drop in cho-
lesterol levels unless they go all the way by cutting all animal pro-
teins from their diet.
Red meat is not the only problem. The consumption of chicken
and fish is also linked to colon cancer. A large recent study examined
the eating habits of 32,000 adults for six years and then watched the
incidence of cancer for these subjects over the next six years. Those
who avoided red meat but ate white meat regularly had a more
than 300 percent increase in colon cancer incidence.^9 The same
study showed that eating beans, peas, or lentils at least twice a week
was associated with a 50 percent lower risk than never eating these
foods.

Chicken has about the same amount of cholesterol as beef, and
the production of those potent cancer-causing compounds called het-
erocyclic amines (HCAs) are even more concentrated in grilled chicken
than in beef." Another recent study from New Zealand that investi-
gated heterocyclic amines in meat, fish, and chicken found the great-
est contributor of HCAs to cancer risk was chicken.^12 Likewise, studies
indicate that chicken is almost as dangerous as red meat for the heart.
Regarding cholesterol, there is no advantage to eating lean white in-
stead of lean red meat.^13
The best bet for overall health is to significantly limit or eliminate
all types of meat—red and white. Dr. Campbell explains further his
view that animal protein (in addition to animal fats) are implicated
in disease causation:
I really believe that dietary protein—both the kind and the amount—is
more significant, as far as cholesterol levels are concerned, than is
