Folic Acid in a healthy Diet

In my Times newspaper 24 November 2006 there was an article that said that folic acid can help in the reduction of heart disease and strokes. Previous research has found that it can help some cancers and Alzheimer's disease. The sources of this folic acid ( vitamin B) are in the following foods, green leafy vegetables such as Brussels sprouts, broccoli, spinach and green beans, oranges, dried beans, peas and lentils. I am hoping to include more salad recipes which include these delicious foods and help us to have a healthy life style and healthy diet.
