Do grilled meats pose a cancer risk? The research says: possibly. According to the National Capital Poison Center, studies have found that when fat drips onto coals, it produces polycyclic aromatic hydrocarbons (PAHs). These may alter a person’s DNA and have been linked to skin, bladder, and lung cancer. Most studies were laboratory-confined until 2016 when a study in Analytical Chemistry connected heterocyclic aromatic amines (HAAs) from cooked meat to prostate cancer in humans. However, the risk is still small. According to biochemical toxicologist Robert Turesky, you can avoid the risk by grilling less often and cutting off the charred bits.
Yes, milk is healthy. But consuming high intakes of dairy products has been linked to cancer, because of milk’s hormone and fat content. For instance, a review of 32 studies in the American Journal of Clinical Nutrition connected a high amount of dairy to prostate cancer. This was backed by the Journal of the American College of Nutrition. Prostate isn’t the only cancer influenced by dairy. In 2014, researchers followed over 22,000 lactose intolerant individuals to record dairy’s impact on health. They reported that lactose-intolerant people have a lower chance of contracting breast, lung, and ovarian cancers. You don’t have to remove milk from your diet, but don’t overdo it, either.
