Special Foods For Better Health
Nutritionists believe that food is a natural pharmacy and that the answer to a lot of our health problems lies in what we eat. Scientists have identified properties in individual foods which appear able to keep specific diseases at bay and which are essential for maintaining a healthy diet. Scientists are still in the early stages of understanding how the various nutrients in food interact with our bodies to contribute to good health.
Olive oil is an excellent source of heart-healthy monounsaturated fats that may lower the bad cholesterol and raise the good cholesterol.

Green vegetables like broccoli and spinach are sky-high in potent anti-cancer compounds like sulforaphane and quercitin. Broccoli, a member of the cruciferous family which also includes cabbage and brussels sprouts, is a rich source of vitamin C and betacarotene. Broccoli is another source which is believed to prevent cancer cells.
The tomato is an excellent food for fighting cancer. The valuable ingredients are betacarotene (converted into Vitamin A in the body), vitamin C and E, potassium and a compound called lycopene.
