Obese women with high intake of vitamin C and B6 associated with lower breast cancer risk – cohort study

Obese women who took vitamin C and B6 at amounts that exceeded the recommended daily intake levels were associated with a lower risk of breast cancer, according to a five-year long South Korean cohort study.

However, no significant association was not observed in women with normal weight.

“Obesity is associated with higher estrogen levels in postmenopausal women due to the aromatase change of testosterone to estrogen in adipose tissue, as well as chronic inflammation status with increased oxidative stress permanently. Thus, the antioxidant effect of vitamin C may be more prominent in women with obesity,” ​the researchers explained.
