Both here in the US and around the world, obesity rates continue to climb. Today, for the first time, more people are classified as obese than underweight, finds a major new study published in The Lancet.
The findings have severe implications for cancer rates. Aside from not smoking, staying a healthy weight is the single largest risk factor related to cancer risk. AICR research links excess body fat to ten cancers, including colorectal, postmenopausal breast and esophageal.
Here in the US, if everyone were a healthy weight, AICR estimates that approximately 128,000 cases of cancer could be prevented each year.
In celebration of Saint Patrick’s day, you’re probably thinking green. We talk about greens a lot here because eating plenty of those green vegetables is a big part of a cancer-preventive pattern of eating.
Research shows that consuming non-starchy vegetables, like dark-colored leafy greens, may protect against cancers of the mouth, pharynx, larynx, esophagus, and stomach while providing fiber and phytochemicals.
The phytochemical beta-carotene, for example, is found in dark leafy greens. As a rule of thumb, the greater the intensity of the color of these vegetables, the more beta-carotene it contains.
Most of you are familiar with “leafy greens” like spinach and deep green colored lettuces. And of course, there are green apples, broccoli and green tea. But if you want to fill your plate with greens today, there are plenty of others you can choose. Many of which researchers are studying for how they play a role in lowering cancer risk. Here’s a few other options.
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.
