In general, it's been found -- both in this study and other studies -- that it's really (women who are) current or recent users of hormones who have an increased risk of breast cancer.

The findings from both studies indicate that the effect of exercise we found in the current study truly represents an enhanced rate of wound healing in older adults.

Even if you do see a small benefit for, say, breast cancer, you couldn't be sure it was due to fat and not due to the fact that the women also increased their fruit and vegetable intake and there was also a small weight loss. I think it's clear this study was a mistake.

One of the problems with a low-fat diet is that it actually drives down the good cholesterol -- the HDL -- in our blood (and that) ... will probably increase the risk of heart disease,

With breast cancer, nothing is straightforward. It makes sense for most people to make their dietary decisions based on what it does for heart disease. That's where the data are most strong.

This does very strongly refute the dominant view in the 1990s, that reducing the amount of fat in the diet would spontaneously lead to weight loss. What's happened to the American diet during this low-fat period is, people were given the idea that if they reduced calories from fat, weight would go down. Clearly, that has not happened.
