London - High calorie intake may increase the risk of breast cancer.
Research based on around 4 000 women has found that those who had the highest energy intake were 70 percent more likely to develop the cancer, irrespective of weight and rates of physical activity.
The study from the University of California examined 1 775 women diagnosed with breast cancer and 2 529 not affected by the condition.
The results found that eating a large number of calories increased risk of the condition.
Just why is unclear, although other research has suggested that a diet high in fat and calories increases circulating oestrogen in the blood, which may fuel cancer growth. - Daily Mail
