...and saturated fats cause heart attacks.
I saw an article about that a few weeks ago. I'm glad the main stream media is starting to catch on.
The article doesn't make mention of what their definition of low carb is. I'm guessing it's not what we talk about in these forums.
This study interests me because...
"Among the foods regarded as complex carbohydrates: rice, pasta, bread and cereals. The digestive system turns them into sugars. Fruits, vegetables and milk products are simple carbs."
You don't often see that in studies. They looked specifically at the amount of grain consumption, so there doesn't seem to be much potential for confounders. It suffers from the unreliability of food recall, obviously, but they probably didn't have much trouble generally separating the heavy grain eaters from the others. I'm looking forward to reading this one.
Then again, we're talking about 200 or so people, and relative risks on the order of 20 to 40% tend not to translate into very significant real life differences.
There is a good book on it as well.
