Some foods naturally contain disease-fighting, health promoting properties, while others contain elements that may hinder your health goals.
Pumpkin Seeds
Pumpkin seeds are high in zinc, which is good for the prostate and building the immune system. They also 
contain fatty acids that kill parasites. Raw pumpkin seeds contain essential fatty acids and beneficial proteins. Roasted seeds contain damaged fat that can lead to plaque in the arteries.
Radishes
Radishes have antibacterial and anti-fungal properties. They contain vitamin C, potassium and other trace minerals.
Sweet Potatoes
Sweet potatoes are an excellent source of carotenoid antioxidants. They contain calcium, are high in vitamins A and C and contain thiamine. Sweet potatoes are high in sugar and should be used sparingly.
Tomatoes
Tomatoes are rich in lycopene, flavonoids and other phytochemicals with anticarcinogenic properties. Tomatoes are an excellent source of vitamin C (the vitamin C is most concentrated in the jelly-like substance that surrounds the seeds). They also contain vitamin A and B-complex vitamins, potassium and phosphorus. A tomato grown in a hothouse has half the vitamin C content as a vine-ripened tomato.
Zucchini (Summer Squash)
Zucchini and other summer squash varieties contain vitamins A and C. They also contain potassium and calcium. The flavor of zucchini is best when it is less than six inches long.
