Consuming too much sugar
By now you’ve heard time and again how bad sugar is for you. It’s been linked to obesity, heart disease, diabetes—and now also cancer. According to a study done at the University of Texas MD Anderson Cancer Center, high amounts of sugar in today’s Western diets may increase the risk of breast cancer. (Learn the symptoms of breast cancer to watch for.) The study found that sugar levels in mice comparable with levels in Western diets led to increased tumor growth. “While done on mice, the researchers did try to make the study as close as possible to what happens in humans,” says Leslie Bonci, MPH, RDN, owner of Active Eating Advice. “The mice were fed sugar in doses similar to what Americans eat daily and these mice were genetically predisposed to breast cancer.” The culprit appeared to be fructose, as it exacerbated the inflammatory process. Stick to natural sugar found in fruit and avoid sugar-sweetened beverages, tabletop sweeteners, candy, and desserts. Plus, load up on these 30 foods that help prevent cancer.
