Many people think of omega-3 fatty acids as being only good for heart health and cholesterol levels, but omega-3 fatty acids have effects on other parts of the body as well, including the metabolism and general organ function. Salmon is rich in these omega-3s and if you are struggling with bulimia nervosa, you should consider adding salmon to your diet immediately. A deficiency in omega-3 fatty acids can lead to more inflammation throughout the body, poor digestive health, and other side effects that can lead to a sedentary lifestyle, poor body image, depression, and another cycle of bulimia nervosa.
