Researchers have just confirmed in a large new meta-study that women with breast cancer can markedly improve their survival by getting more vitamin C in their diet and through supplements. The new study included over 17,600 women with the cancer, and is the largest of its kind. It showed that for every extra 100 mg of vitamin C obtained daily through the diet, a breast cancer patient’s risk of dying decreased by a stunning 27%. Supplemental vitamin C was slightly less impressive, decreasing risk of mortality by 19% for every extra 100 mg of supplemental vitamin C per day. Dietary vitamin C is likely better because of all the other anti-cancer nutrients that are found in vitamin C-rich foods. One great source of vitamin C that’s easy to find is freshly squeezed orange juice, which delivers 124 mg per cup and contains other healthy compounds like limonoids, which have been shown in other studies to also fight breast cancer. Other good sources of vitamin C are acerola, rose hips, guavas, red and yellow peppers, grapefruit, lemons, limes, black currants, strawberries, kiwi fruit, apricots, vegetable juice and tomatoes. Once again, a healthy diet has been shown to be of utmost importance in fighting cancer.
