Vitamin C

Vitamin C is one of the safest and most effective nutrients, experts say. It may not be the cure for the common cold, Vitamin C does help to heal wounds, prevent cell damage, promote healthy gums and teeth, strengthen the immune system, and absorb iron. It also helps neutralize free-radicals in cells that promote aging, fight bacterial infections, and aid in the production of red blood cells.

All fruits and vegetables contain some amount of vitamin C. Foods that tend to be the highest sources of vitamin C include green peppers, citrus fruits and juices, strawberries, tomatoes, broccoli, turnip greens and other leafy greens, sweet and white potatoes, and cantaloupe.

Other excellent sources include papaya, mango, watermelon, brussel sprouts, cauliflower, cabbage, winter squash, red peppers, raspberries, blueberries, cranberries, and pineapples.
