Today’s Headlines: Why You Should Snack on Nuts, The Link Between Obesity and Cancer, and How Your Coffee Cravings May Be Determined by Your DNA

Adding nuts to your daily diet may significantly reduce inflammation in your body. A new study has shown that eating a handful of nuts several times a week is beneficial. “Nuts may lower inflammation because they contain fiber, magnesium, antioxidants and other health-boosting ingredients, the researchers write. People who ate nuts at least five times per week had 20 percent lower levels of C-reactive protein (CRP) compared to people who never or rarely ate nuts. They also had 16 percent lower levels of interleukin-6 (IL-6), another inflammatory marker.” The type of nut did not seem to matter, although researchers noted that peanut butter did not have the same beneficial results.

A higher BMI may put you at risk for cancer. In a new analysis of more than 1,000 studies, researchers found that being overweight or obese could increase your risk of eight types of cancer. “While previous studies have found obesity can increase the chances of developing health issues like diabetes and heart disease, which can also raise the risk of early death, study authors noted excess weight can specifically drive cancer growth by promoting inflammation…Being overweight or obese leads to an overproduction of estrogen, testosterone and insulin, which can further fuel the progression of cancer.” Researchers identified the eight diseases as liver cancer, pancreatic cancer, gallbladder cancer, stomach cancer, thyroid cancer, ovarian cancer, brain tumor meningioma, and multiple myeloma.

Whether or not you crave coffee may be related to your genes. Researchers have found that a variation of a gene may determine why you need your daily coffee fix. “Those with a gene variant called PDSS2 drank one cup less a day on average than those without the variation, the investigators found… The findings suggest that PDSS2 reduces cells’ ability to break down caffeine. That means it stays in the body longer. The upshot: People with the gene variant don’t need as much coffee to get the same caffeine hit as those without it, the researchers said.” More research needs to be done to confirm these new findings and establish the biological cause and effect.
