Ever wonder about the cause of high cholesterol, heart diseases, strokes, etc....? We "civilzied" humans have done lots of weird stuff that our bodies aren'r really designed for. Our species wasn't designed to sit and stare at computer screens 8 hours or more a day. We rarely use our legs. Just hop onto a vehicle, a car, a motorcycle, etc. and push the gas pedal. We rarely get 8 hours of sleep per day. We rarely breathe fresh air outdoor. After work, we get home and lock ourselves inside the box, sit and watch TV or surf the Net for another 5 or 6 hours. Then fill our belly with junk food. The Gym is a product only found in modern society. Our ancestors didn't need it and yet they were a lot more fit than us. We live longer than them not because we're healthier, but because modern technology is able to load our body with tons of powerful chemicals to keep it going. So, you dont' really need any 'heart attack proof' diet, you just need to undo those nasty habits above. Eat a healthy, balanced diet (vegetarian or not), exercise a lot (especially outdoor aerobics like jogging, biking, hiking...), and maintain a positive and healthy mind. That's all you need..
