The largest study ever to ask whether a low-fat diet reduces the risk of getting cancer or heart disease has found that the diet has no effect.
The $415 million federal study involved nearly 49,000 women ages 50 to 79 who were followed for eight years. In the end, those assigned to a low-fat diet had the same rates of breast cancer, colon cancer, heart attacks and strokes as those who ate whatever they pleased, researchers are reporting today.
Now of course here is a question of the women in the study what were their family history for heart disease/high blood pressure/cholestoral/etc. How did their livers function. Did they excersise. Did they have similar rates of stress...
because you see .........All these things impact how the body functions, how it metabolizes and...ya know... your states of health.
The problem is of course you can't make a master study with that many variables.... Science just doesn't work that good yet. So we now have science closing the book on something that may be very valid
