Try many different ones. Each fruit has a different set of beneficial plant substances such as carotenoids and flavonoids that have antibacterial, antiinflammatory, antitumor and antioxidant properties. Reduce your fruit juice intake if you are diabetic. Avoid drinking lots of fruits juices since they contain a large amount of fructose. Fructose can elevate blood sugar and lead to weight gain.
    Wash all fruits before eating to reduce pesticides and contamination by germs. Buy organic when possible.

Tomato - Botanically speaking, a tomato is a fruit since it is the ovary, together with its seeds, of a flowering plant. However, from a culinary perspective, the tomato is served as part of a main course of a meal, as are other vegetables, rather than at dessert.
Watermelon is a fruit that has a pinkish color which is due to the high lycopene content. Watermelon is a delicious furit dessert when eaten with feta cheese.

Vegetable and Fruit Powder
Immunity and antioxidant capacity in humans is enhanced by consumption of a dried, encapsulated fruit and vegetable juice concentrate.
J Nutr. 2006 Oct;136(10):2606-10. Nantz MP, Rowe CA, Nieves C Jr, Percival SS.
Food Science and Human Nutrition Department University of Florida Gainesville, Florida 32611.
We hypothesized that a commercially available encapsulated fruit and vegetable juice powder concentrate could support functional indices of health due to increased intake of various phytonutrients. This was a double-blind, randomized, placebo-controlled investigation of 59 healthy law students who consumed either fruit and vegetable juice powder concentrate or placebo capsules for 77 days. Blood was collected on d 1, 35, and 77 to examine the number of circulating alphabeta- and gammadelta-T cells, cytokine production, lymphocyte DNA damage, antioxidant status, and levels of carotenoids and vitamin C. A log of illnesses and symptoms was also kept. The FVJC group tended to have fewer total symptoms than the placebo group. By day 77 there was a 30% increase in circulating gammadelta-T cells and a 40% reduction in DNA damage in lymphocytes in the fruit and vegetable juice powder concentrate group relative to the placebo group. Plasma levels of vitamin C and of beta-carotene, lycopene, and lutein increased significantly from baseline in the fruit and vegetable juice powder concentrate group as did plasma oxygen radical absorptive capacity (50%). Interferon-gamma produced by phorbol-stimulated lymphocytes was reduced 70% in the fruit and vegetable juice powder concentrate group, whereas other cytokines (IL-4, IL-6, transforming growth factor beta) were unchanged relative to treatment or time. fruit and vegetable juice powder concentrate consumption during this study period resulted in increased plasma nutrients and antioxidant capacity, reduction in DNA strand breaks, and an increase in circulating gammadelta-T cells.

Fruit Juice and Weight Gain
Experts generally recommend limiting children's fruit juice drinking due to potential excess calorie intake. The higher a child's fruit juice intake, the greater the gain in body fat over time -- generally among children who are initially overweight or on the verge of becoming so. Children who eat whole fruits gain less body fat. Many fruit juices typically contain added sugar, and therefore, calories. The fruit juice boxes so popular with kids typically contain about 100 calories each. So a few of those each day can start to add up. Pediatrics, November 2006.
   However, pure fruit juice should not put weigh on kids if drank in moderate amounts. Contrary to popular belief, drinking pure 100 percent fruit juice does not make young children overweight or at risk for becoming overweight. Pure fruit juice provides essential nutrients and, in moderation, may actually help children maintain a healthy weight. The key here is moderation.

Fruit juice or eating fruit -  which is better?
Researchers have for years believed that vegetable and fruit juice do not have the same health benefits as a their whole fruit counterparts. But a study conducted by British nutrition researchers challenges this view. It is likely that 100 per cent fruit juice extracts could be just as effective in reducing the risk of some cancers and cardiovascular disease. the positive impact fruits and vegetables offer comes not from just the fiber, but also from the antioxidants, which are present in both the fruit juice as well as the whole fruit and vegetables.

Fruit drinks and diabetes
Sweetened fruit drinks are marketed as a healthier alternative to non-diet soft drinks but are just as likely to cause weight gain and increase the risk of diabetes.

Fruits and prescription drug absorption
Juice from certain fruits such as grapefruit, oranges, and apples, as well as the whole fruits, decrease oral absorption of some drugs by blocking an intestinal uptake transporter. Dr. David G. Bailey had previously reported that grapefruit juice blocks the drug-metabolizing enzyme cytochrome p450 3A4, boosting blood concentrations of some drugs to potentially toxic levels. Since then, nearly 50 medications have been found to carry the risk of grapefruit-induced adverse drug reactions. When consumed with either a glass of grapefruit juice or water containing the grapefruit flavonoid naringin, antihistamine fexofenadine drug absorption is reduced by half. Naringin has influence on the absorption of water soluble prescription drugs. The effects of fruits may be noticed with immunosuppressant cyclosporine, the antineoplastic agent etoposide, some beta blockers (atenolol, celiprolol, talinolol), and some antibiotics (ciprofloxacin, levofloxacin, itraconazole). Prescription medications should be taken at least 4 hours after fruit juice intake.
