Eating a diet that is low in red meat and processed foods may help breast cancer survivors prolong their life, according to new research.

Researchers at Kaiser Permanente in Oakland, California say that following an eating plan that includes plenty of vegetables, fruit and whole grains could help women avoid death from other chronic diseases and cancers, Reuters Health reports.

The diet was not linked specifically to a lower risk of dying from breast cancer, they add.

As part of the study, published in the Journal of Clinical Oncology, 1,901 women with early-stage breast cancer provided details on their diet, exercises habits, weight and other health factors.

After an eight-year follow-up, the scientists found that women who had eaten the healthiest foods were approximately 50 per cent less likely to have died, compared with those who ate the lowest amounts.

Factors such as the initial breast tumor, treatment type and smoking habits were taken into account.

Lead researcher Dr. Marilyn L. Kwan said that the study shows “eating a more healthful diet is beneficial for overall survival.”

It is well known that a balanced diet full of nutrients can benefit overall health. Those who cannot get all of their vitamins from food may use nutritional supplements to help them stay healthy.
