Low Fat Diet
JAMA has a well-publicized article this week on results from the Women's Health Initiative showing to benefit from low fat diets in terms of cancer or cardiovascular risk.
A few caveats--it is only 7 years of followup, which might be too short to see a difference, compliance is unclear, and we already knew that total fat doesn't matter, it's saturated fat.
But let me just harp again on the silliness we have of thinking that tweeking our diet in certain ways affects our health. We can sum up what we know about nutrition as Marion Nestle does:
1. Eat less calories.
2. Eat more vegetables.
3. Move more.
Any advice more specific than that should come from your doctor.
