People think of certain foods more often in the summer – barbecue on the grill, or maybe ice cream or watermelon. They can actually crave certain foods during various seasons, according to nutritionist Trisha Mandes and USC Public Health Professor Brie Turner-McGrievey. The reason is often that people can have low-grade addictions to some foods because they release chemicals in the brain that make them feel good – an opiate-like effect, says Mandes. High on the list of addictive foods is cheese.
