Does anyone know what are good foods and vitamins for getting a healthy heart and improving circulation?

Omega 3's and flaxseed oil.
Increased activity, daily, especially walking
Everything green, yellow, or leafy and lean meats
Salmon
Decreased stress or stress off-set with exercise so that it is not turned inward
Low-fat and high vitamin foods
Whole grain foods like oatmeal and many good cereals
Avoid products that have high fat, high cholesterol or have "high fructose corn syrup" or "enriched" anything in the first five ingredients. Lots of fruit and vegetables, lots of water, and a good exercise regimin.
Hope that helps.
