What can someone eat if he or she had coronary heart disease?

Anything... but...: You can eat anything, but in reality your best bet is to switch to a more healthful diet which is what i call "flexeterian" -- mostly plant based products (vegetables and fruits and only 100% whole grains) and avoidance of most animal products, dairy, etc. When you do eat meat, limit yourself to small portions of poultry or fish that is steamed or grilled.

Its what youu should: Stay away from fatty foods fried foods eat more whole grains protein etc.
