Epidemiological studies do
not support the notion that diets high in animal fats cause heart disease.
For instance, mortality from coronary heart disease in southern India
was found to be seven times higher than in the north and people in the
south died on average 8 years earlier, despite the fact that people in
the north ate 19 times more fat (mostly animal fat) and also smoked much
more.
In addition, the Masai people
(Kenya) probably have the highest intake of animal fat in the world, but
studies have shown that abnormalities on electrocardiography were far
less frequent than in Americans and raised atherosclerotic lesions were
rare.
In 33 countries, an increased
intake of animal fat was followed by an increased coronary morality in
30 time periods, but in 23 other time periods an increased fat intake
was followed by a decreased mortality.
Meticulous investigations of
the food consumption in 21 studies including more than 150,000 participants,
with and without coronary heart disease, did not find a correlation of
dietary fat consumption in accordance with the current view.
More importantly is that systematic
reviews of the various trials on the connection between fat intake and
heart disease contradict any link. Not
a single death has been prevented by diet in these trials. Researchers
claiming the validity of the diet-heart idea do so by excluding negative
trial results from their analyses.
