Eating too much saturated fat
Foods high in saturated fat, such as potato chips, pizza, and ice cream, may seem comforting, but eating excessive amounts can create anxiety. A 2012 study from Université du Montréal found that mice fed high-fat diets showed signs of increased stress. “You need a small amount of saturated fat for optimal health, but in excess it triggers bacterial endotoxins that cause inflammation in the gut, and that inflammation is linked to anxiety,” says Nielsen. To get the small amount of saturated fat that your body needs, opt for healthy choices such as salmon, avocado, olive oil, and raw nuts instead of hamburgers, bacon and candy.
