When Food and Pills Clash

I appreciate articles like this from the mainstream media, which often tend to oversimplify instead of pointing out complexity in healthcare (as well as many other subjects).  To be fair, it is difficult to express complexity given limitations of space, number of words etc..In any case, this article getis it right.

Fresh Concerns on How Diet and Medicines Interact, From Pepper to Pomegranate..
(..)
Grapefruit is one of the most extensively studied foods for its impact on medication. Compounds in the fruit can increase the potency of statins and other medications to potentially dangerous levels by inhibiting cytochrome P450, a family of enzymes that break down the drug. Research indicates that drinking just one eight-ounce cup of grapefruit juice a day increases the strength of the drug.

Recently, animal and laboratory studies have suggested that other fruits, including pomegranates, oranges (especially those from Seville), cranberries, grapes and black mulberries, could have a similar, although less robust, effect on statins in the body. Pomegranates and cranberries are frequently touted as healthy foods because of their high quantities of antioxidants, which supposedly remove free radicals from the body and slow the onset of disease and aging.

In the lab, some scientists' work raises similar concern about olive oil and some statins. The oil, a principal part of the Mediterranean diet and believed to lower the risk of heart disease, also appears to contain compounds that inhibit the drug's breakdown, according to researchers in Spain. The effects of olive oil likely aren't as strong as that of grapefruit, but more studies are needed to figure out what quantities might actually impact humans, say experts.
