More than 4,000 women followed the Mediterranean diet supplemented with olive oil, the diet with nuts, or a low-fat diet in a JAMA: Internal Medicine study. In five years, women on the Mediterranean diet with olive oil had a 68 per cent lower risk of breast cancer than those on the low-fat diet. The nut group had a lower risk that was not statistically significant. Women with the lowest risk ate about four tablespoons of olive oil per day.

Women who drink at least two cups of black tea daily have a 32 per cent lower risk of ovarian cancer compared with those who drink one cup or less per day, according to a large study published in the American Journal of Clinical Nutrition. That’s just one of several studies pointing to anti-cancer properties of tea. This may be due to certain flavonoids (antioxidant compounds synthesised by plants) in black tea. The study did not include other types of tea, though studies have shown benefits in other varieties.
