Diabetic Mediterranean Diet 
From time to time some research surfaces that contradicts my experience to great degree, and this one is a typical example. I was miserable on the Dr.Weill anty-ingflammatory diet which emphasized the low-fat, high whole grain, a lot of veggies, limiting meat, especially red meat. In my case elimination of grains an sugar and eating more red meat and eggs put me back together, including mood, weight, general health. Former vegetarians say the same.
I just started a new job and we teach that people need meat! The amino acids from protein make neurotransmitters which run our brain. People who do not take in enough quality protein typically experience depression, anxiety, lethargy, and sleep disturbances. And our brains are made of fat, limit fat and the brain suffers. Blahh… these types of nutrition studies just confuse the public.
Also… Arachidonic acid is found in Red meat, not so much in poultry, fish, eggs. And if these omnivores are eating crapy beef from fast food, of course their moods suck compared to the vegetarians. Their taking in too much other junky trans fats and processed carbs, both of which will cause poor moods. 2 weeks isn’t a very long time for a study to occur, and 39 people is not a very large study group.
I’ve skimmed the full text and will make a full report in a blog post… sometime soon 😉
(Two week study! Funny thing is in the “happy” group they increased the w6/w3 dietary ratio by 60%!!)
Emily, I look forward to your post. I haven’t commented much at your blogs lately but still read them (and Brenna’s) w/o fail.
Galina, I’m glad you found a way of eating that works well with your metabolism. We all need to experiment that way.
My opinion is I think they need to give the test a longer period than 2 weeks. For me, a little bit too short to get any real understanding!
