A small randomized, controlled trial, conducted in North Carolina, sought to determine whether tomato (Lycopersicon esculentum syn. Solanum lycopersicum, Solanaceae) juice could increase serum lycopene levels in men undergoing intensity-modulated radiation therapy for prostate cancer.¹ While larger, better designed studies are needed, the trial did find that 8-10 oz. of tomato juice consumed daily increased serum lycopene levels and also showed a positive correlation between lycopene consumption and weight and body mass index.

Tomatoes contain B complex vitamins as well as vitamins C and E.² Mineral content includes phosphorus, potassium, and sulfur. Other components include beta-carotene, histamine, and quercetin. However, tomatoes are most known for their lycopene content, which has been touted as an antioxidant that can protect against such conditions as strokes and cataracts and may help in the prevention of certain cancers and in scurvy. They have been used as an antiseptic and as laxatives, aiding digestion for those with inadequate stomach acid. Tomatoes have also been used for headaches, high cholesterol, and hypertension. They are said to benefit the liver and aid in the elimination of uric acid.

While tomatoes are acidic, they have an alkalizing effect on the blood. Their energy is considered cool with a sweet and sour flavor. Because they are part of the nightshade family, some people may have adverse reactions to them as they can decrease iron and calcium absorption.²
