A new report by the World Cancer Research Fund (WCRF)/American Institute
for Cancer Research warns that excess body fat increases a person's risk for
numerous cancers. The report states in no uncertain terms that the more you
weigh, the greater your risk of developing cancer. It is a rigorous study on the
links between food, physical activity and cancer-and sets out sources of risk.
Individually (except for smoking) these risks are quite small. Roughly
speaking, smoking is responsible for a third of cancers; poor food and lack of
exercise result in another third; and other causes account for the rest. Some of
this last third are known: genetic predisposition, ultraviolet sunlight and
pollutants such as pesticides. But the picture is incomplete.
gives nine recommendations to help avoid cancer.
1. Be as lean as
2. Be active.
3. Avoid energy-dense foods and sugary
4. Eat mostly plants.
5. Back off on the red meat.
6. Limit alcohol.
7. Avoid salty foods.
8. Get your
daily nutrients from the foods you eat, not from supplements.
Breast-feed your baby.
This release ignited anger in parts of the red
meat community this week.
"WCRF's conclusions are extreme, unfounded and
out of step with dietary guidelines," said American Meat Institute Foundation
Vice President of Scientific Affairs Randy Huffman, Ph.D. "Headlines associated
with this report may give consumers another case of nutrition whiplash. The
consistent finding in diet and cancer research is inconsistency. No health
groups should be dispensing clear-cut recommendations on specific foods when
studies continue to contradict each other time after time."
stressed that the recommendations stand in sharp contrast to mainstream advice
in the U.S. Dietary Guidelines.
