Eating foods with a high glycemic index (GI) can make your blood sugar rise higher and faster after eating. Theoretically, that could cause unhealthy levels of hormones like insulin, which seem to promote development of some cancers, including breast.
However, research suggests that glycemic index by itself has little to no relation to breast cancer risk.
An analysis of 19 studies found no link between breast cancer risk and diets high in GI beyond what could occur by chance. Even glycemic load (GL), which takes portion size of foods into account, showed no significant link to breast cancer risk. The links were not consistent and could reflect other qualities of those diets. Another analysis that included only studies with a stronger design that follows people over time (called prospective cohort studies) found a weak five to six percent increase in breast cancer risk when comparing diets at the very highest to the very lowest glycemic index or glycemic load, respectively.

Excess weight increases the risk for many chronic diseases, including 11 cancers, but physicians may not bring up weight loss with their patients because they’re pressed for time, fear patients may be offended, or worry that bringing up weight loss won’t make much of a difference.
Now a new study published in The Lancet suggests that if primary care doctors take just 30 seconds to refer patients to a weight management program, physicians can help overweight and obese patients lose weight.
As we head toward the holidays, you’ll be hearing advice on how to avoid packing on the pounds – and then how to lose it. And it’s a good idea to pay attention, because a new study highlights that Americans really do gain weight over the holidays.
That’s not good for cancer risk, because too much body fat links to increased risk for 11 cancers, including colorectal and postmenopausal breast.
The recent study, published in a letter in the New England Journal of Medicine, also sheds light on just how long losing the weight gain may take.
Using data from almost 1,800 adults weighing themselves on electronic wireless scales over a year’s time, researchers found that Americans begin gaining weight in early November and continue until early January. It takes until mid-October to get back to their lowest weight. Not unique to the US, people in Germany and Japan experience similar trends during their popular holidays.
