7 small changes to your diet can have a big impact on your health.

1. Get your greens.
According to the American Cancer Society, Asian women have a breast cancer rate one-fifth that of U.S. women. While soy often gets the credit, cruciferous vegetables are also proving to be preventative. One study showed that Chinese women with the highest levels of isothiocyanate- a compound found in broccoli, kale, brussels sprout, and other cruciferous vegetables-cut their rate of breast cancer by 50 percent.

2. Make every day D-day.
Low vitamin D levels have recently been linked to an increased risk of everything from heart disease to depression. Now researchers have made a connection between the nutrient and breast cancer: A study in the Annals of Epidemiology found that pre-menopausal women with higher intakes of vitamin D had a roughly 30 percent lower breast cancer risk. Fish is your best dietary D source- try salmon, trout, and sardines.
