This fluid contains flavonoids that have anticlotting properties, and could, at least in theory, reduce the risk of heart attacks. The producers of Fruitflow certainly think this is the case. This patented tomato-extract product is being added to various drinks with hopes of improving cardiovascular health. In one study, blood “stickiness” was reduced by an average of 70 percent in 220 volunteers who drank a juice containing Fruitflow, with the effect lasting for eighteen hours. Tomato juice itself may provide a similar benefit.

Whether it was made by a chemist in a lab or by nature in a bush does not matter. What matters are the results of studies that have been carried out on the safety and efficacy of the substance. There is no shortage of cholesterol-reducing claims on behalf of dietary supplements formulated from natural products. Some, such as guggulipids extracted from the guggul tree, seem exotic, while policosanol from sugar cane or allicin from garlic sound more mundane. Promoters of all such products muster up studies to hype their wares, but the scientific consensus is that the evidence is pretty thin.

During eight years of follow-up, 1,320 of the men were diagnosed with prostate cancer, but no relationship was found between the blood levels of lycopene and occurrence of the disease. Of course, this research does not signal the end of the debate. We cannot just dismiss the studies that have shown an association between consuming tomatoes and protection from cancer. Let’s remember that tomatoes are chemically complex and contain numerous compounds besides lycopene, compounds that may—either alone or in combination with lycopene—act as anticancer agents.
