In a study to be published next week, with the National Institute of Health and AARP it was found that older people who consumed the highest levels of calcium (1530mg for women, 1881mg for men) had lower risks of cancer. In particular colon cancer. However researchers state more studies are needed.
Calcium of course is also great for bone health so why not aim to drink a couple glasses of low fat milk a day and a yogurt or get calcium fortified orange juice, it also tastes great.
