Critiques of the science behind plant-based diets

I’ve been reading a lot of blogs about dietary studies. A blog of particular interest is Raw Food SOS by Denise Minger. One of her posts tore apart Ancel Keys’ 22 country data. That data is often cited as proof that dietary fat causes heart disease. By the time Denise Minger got done with it, the data from the 22 countries more likely proved only that richer countries that could afford better medical care were better able to determine cause of death. In other words, the Keys study and data were rendered meaningless.

And another post dissects the movie Forks over Knives and critiques the science in that movie. So far, it isn’t looking good for the movie. Forks over Knives promotes a plant-based or vegan diet. I tried a vegan diet for about three months not so long ago. I ran into problems with it. I began developing a physical form of depression. Fortunately, my mood was still generally good. I had my blood checked, and my cholesterol had dropped too low. The total was 147. My psychiatrist was concerned. He wants to see the total be at least 160. Low cholesterol is associated with depression and other mental disorders. So I stopped being vegan and eventually recovered. As you can tell, I am not a fan of veganism. For me, at least, veganism is a dangerous diet. Generally, though, depression is more common among vegans, so it isn’t just me. One of my lowest total cholesterol readings, 125, coincided with my first round of NutriSystem back in 1990 or so. It also coincided with my diagnosis of bipolar disorder. And that, folks, is why I have adjusted my diet. I’m trying to keep my cholesterol levels from falling. I’ll have blood drawn to test cholesterol on Thursday to see if my strategy is working. I’m optimistic. My mood has been good so far this round.
