Serotonin levels inside the body plays a very big role in a person’s mood, after regulating the function of the digestive tract. Now, what kind of foods can increase serotonin levels? Well, foods rich in Omega 3 fatty acids will help in the department and one of those foods, actually nuts, is the walnuts. Top it on your salad or eat a handful each day and this will make you sport a smile all day long.
Note: One serving of walnuts is all you need. Do not overeat and choose to buy the roasted and not the salted ones.
