I'd like to think my lecturers are not complete idiots, rather i'd hope they're not.
My lecturer who takes classes on psychosocial factors affecting health and nutrition played an 18 minute video by Dean Ornish, MD.
Feel free to do a search on him. A good summary of what he basically says is posted on this site
Here is a snippet from the site - its what they teach med students these days.
These should be avoided:
* Meat of all kinds -- red and white, fish and fowl (if we can't give up meat, we should at least eat as little as possible)
* Oils and oil-containing products, such as margarine and most salad dressings
* Nuts and seeds
* Dairy products (other than the nonfat ones above)
* Sugar and simple sugar derivatives -- honey, molasses, corn syrup, and high-fructose syrup
* Anything commercially prepared that has more than two grams of fat per serving
No advocados, nuts or seeds as well as red meat =/
