Can foods really reduce cardio vascular disease risk like they say in ads?

Yes and no: The following dietary rules reduce risk: eat fruits and vegetables 3-5 servings per day. Fiber 14 g/day. Avoid trans ( as low as possible) and saturated ( no more than 10% total calories) fats. One to two servings of oily fish/wk - or equivalent in fish oil or omega 3. 1-2 drinks alcohol per day. If you have high BP dietary restrictions on sodium are important.
