Healthnotes Newswire (June 7, 2007)—Many women start thinking about calcium and vitamin D after menopause, but new evidence suggests that paying attention to these nutrients before menopause could protect against breast cancer.
The new study, published in the Archives of Internal Medicine, was drawn from the large, long-term Women’s Health Study. The analysis included information about diet and cancer diagnoses over a ten-year period from 10,578 premenopausal women and 20,909 postmenopausal women.
Some of the richest sources of dietary calcium are green leafy vegetables, such as kale, spinach, and broccoli, as well as sea vegetables such as kelp and dulse. Figs and some nuts and seeds also provide high amounts of calcium. Vitamin D has few natural sources (primarily egg yolk and fish oil) but the body is able to make plenty when it has adequate sun exposure.
