Definitely. That's why I like Chipotle. Some foods leave you feeling gross and malnourished. These types of foods are usually densely packed with calories. (i.e. candy bars, in and out, etc.) At Chipotle, however, I can eat massive quantities of food and afterwords I feel like I have been nourished without intaking too much fat and sugar. But this isn't just a commercial for Chipotle, most homemade foods are better than going out to eat. But food can definitely have an effect on mood, both positive and negative.
