For postmenopausal women who are overweight, it makes sense that losing weight could reduce their risk of breast cancer because being overweight or obese increases the risk. But when overweight women are working to shed pounds, is it primarily exercise or cutting calories that makes more of a difference in lowering the risk?
Both, suggests a new study, with weight loss fueled primarily by exercise possibly leading to even more benefits – at least in the short-term for certain markers of breast cancer.
The study is one of the few randomized controlled trials that focuses on teasing apart the effect of diet versus exercise on breast cancer risk. It was published this week in Cancer Epidemiology, Biomarkers & Prevention.
Previous research has shown that too much fat tissue can place the body in a constant state of inflammation. That leads to high levels of hormones and other proteins that can spur cancer cell growth. How exercise alone can affect inflammation and hormones is one of the big questions under study. Continue reading
Just in time for your New Year’s resolution to eat healthier and lose weight, US News published Best Diets 2016, a comprehensive review of diets of all kinds, including for overall health, weight loss and chronic disease prevention. They didn’t include lowering cancer risk in their analysis, but I couldn’t help but notice that most of the highest ranking diets would work well with AICR’s New American Plate model – designed for reducing risk of cancer and other chronic diseases.
They asked experts in nutrition and weight loss to rate – using the research behind them – how strong the diets are for long and short term weight loss, nutrition, safety, preventing and managing diabetes and heart disease, and how easy it is to follow. The DASH diet (to lower hypertension)won in the most categories, with Weight Watchers ranking highly too. Others scoring well were a diet for brain health (MIND) and for lowering cholesterol (TLC).

Straight from Nashville, we’re just back from the annual Food and Nutrition Conference and Expo – a meeting highlighting the latest research on how foods affect our health and diseases, such as cancer risk. It’s a conference geared towards dietitians, so it’s also a place where companies showcase their health-related foods.
What were the big food trends and research takeaways related to cancer risk? Here’s a few of the conference highlights.

several cereals are now incorporating sorghum
– Beans and whole grains are big. This is a crowd that loves these foods – as do we here at AICR – but there appears to be a revival of beans and lentil products making their way into the supermarkets. There were numerous new ideas to cook with lentils, a high protein and high fiber food, including these recipes: Coconut Cream Overnight Oats and Lentils and Lentil Fudge.
The ancient grain sorghum also appears to be increasingly making its way into products. It’s drought-resistant and gluten free, two traits that are making it popular. (Plain, it tastes similar to barley.) Sorghum can be served as a hot breakfast cereal, as a side or salad mixed with vegetables, or in stews and soups, like this Chicken, Leek and Sorghum soup.
