1. Whole grains
According to a Havard study, whole grains can decrease coronary heart disease risk by as much as 40 per cent. The soluble fiber in whole grains also helps lower cholesterol levels. Stock up on whole grain cereals, crackers, pasta and rice, but don't forget to check the labels -- "multi-grains" are not the same as whole grains. If you don't see the word "whole" towards the start of the ingredients, it's not whole grain.
