prevent the progression of breast cancer cells, but the disease must remain wary, fortifying the body with nutrients carotenoid potent against breast cancer.
Scientists say that women who had high levels of different carotenoids in the blood, a risk 15 to 20 percent less likely to develop breast cancer than women with lower levels of carotenoids.
Carotenoids are pigments responsible for the bright colors of plants. The main sources of carotenoids include carrots, which are rich in alpha-carotene, sweet potatoes and green vegetables, which are rich in beta-carotene, and lycopene-rich tomatoes. Green vegetables are also a good source of lutein + zeaxanthin. So a diet high in carotenoid-rich fruits and vegetables can offer many benefits, including a possible reduction in breast cancer risk.
Carotenoids function as antioxidants and free radicals from absorbing excessive metabolic outcomes. If too many free radicals in the blood, it will cause oxidative stress and prolonged oxidative stress can lead to diseases such as cancer.
"So someone needs more supplies of antioxidants in the body to ward off free radical damage," says A. Heather Eliassen, author of the study and an assistant professor of medicine at Harvard Medical School, as reported thedoctorwillseeyounow.
One interesting finding is that there is a relationship between blood levels of carotenoids in the development of breast tumors have estrogen receptor negative (ER-). Eliassen said that because of ER-breast tumors are more aggressive will be more difficult to treat, but carotenoids may help treatment. Researchers also found that carotenoids also effectively provide protection to women who smoke. Nicotine in cigarettes may increase oxidative stress, but carotenoids are still able to provide protection against him.
But the results also showed that the protective effect of carotenoids more benefit to women with a body mass index (BMI) lower. Excess weight is one of the sources of oxidative stress that is difficult to overcome if only relying on carotenoid diet alone without weight loss efforts. Researchers recommend to increase the consumption of fruits and vegetables or a healthy diet to protect yourself carotenoids breast cancer. The results are published in the Journal of the National
