One way or another, they come from the food we eat. It seems obvious then that the composition of our diet can affect our molecular makeup, and consequently our health. But the relationship between diet and health is not a simple one. Food is chemically very complex. An apple, for example, is composed of over 300 different compounds. A single meal can flood the body with thousands of compounds, many of which have never been isolated or identified. While nutrition is obviously an important determinant of health, it is folly to think that one can introduce something as complicated as food into something as complex as the human body and make easy predictions about the outcome.
There is no doubt that antioxidants from fruits and vegetables are an important part of our diet, but the relevance of a single food or drink having more or less of these compounds is questionable. What matters is our total antioxidant intake. On a weight basis, acai berries may have a higher concentration of antioxidants than apples, but it is certainly easier to load up on apples. However, there is another important issue. The antioxidant potential of a food is determined by a laboratory measurement.
And there is even some hope for cancer prevention. In the lab, tangeretin inhibits the growth of human mammary cancer cells, just like the widely used drug tamoxifen. In live animals, though, not only did the compound not offer protection, it neutralized tamoxifen’s inhibitory effect. It seems then that women on tamoxifen therapy should not attempt to lower their cholesterol with citrus-peel products. For others, the flavonoids found in citrus products hold potential, although the adjective “super” to describe them appears to be somewhat premature.
