Lung cancer is the leading cause of cancer death in the US and smoking is by far the largest risk factor – linked to about 90% of these cancers, according to the CDC. Among other lifestyle factors, researchers are looking at how diet may play a role and this week, a new study found an association between glycemic index and lung cancer.
Glycemic index (GI) is a measure of how much a food with carbohydrates increases your blood sugar. Foods like sugary beverages and cereals made with refined grains are examples of foods high in GI. Previous studies have found associations of GI with other cancers, including colorectal and stomach cancers. AICR’s CUP report on endometrial cancer in 2013 found that that a high glycemic load (related to GI) diet increases risk for this cancer. Read more… “New Study: Glycemic Index and Lung Cancer”
How messy is your kitchen? A new study suggests that chaotic environments, such as a messy kitchen, and our mind-set in that environment may affect our ability to make healthy choices when it comes to snacking.
Choosing healthy meals and snacks can help to maintain a healthy weight and decrease cancer risk. This means that by decreasing chaos and feeling more in control, you may make it easier to eat healthy for cancer prevention.
Female college undergraduate students were put into either a standard kitchen or a messy chaotic kitchen. The standard kitchen was organized and quiet with no disruptions. In contrast the chaotic kitchen was messy with tables out of place and pots and pans scattered around. During the experiment, the chaotic kitchen participants were interrupted by researchers moving tables and banging put and pans as they cleaned up the mess.
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.
