M: Finding comfort in food. Eating the right dishes can lift our spirits and swallow up stress. Well, here with more on how food affects our mood is Dr. Susan Kleiner, a nutritionist, and the author of The Good Mood Diet. Susan, good morning.
W: Good morning, Kim Bold.
M: So I’m very curious about this. Are there foods that actually have happy chemicals in them?
W: Oh, absolutely. (1) You know, how we feel, how we cope with stress, how we think, and how clearly we think are all directly affected by the food that we eat.
M: OK. We actually went out and asked people what food they ate in order to make themselves happy. And they said that some kinds of food do make them happy, such as chocolate, pizza, Thai food and etc. (2) As for me, pizza would be my happy food. But those aren’t the foods that actually make you happy. Right?
W: Well, it could be. You know, all of those are part of it. But there are foods that really directly affect our brain with certain chemicals. (3) Fish is really a big happy food. It’s got protein in brain, and it is free of fat and full of vitamin D. All of those help raise our neural chemistry and that makes us feel happy. (4) Potatoes, cereals and great carps actually get protein into the brain. Fruits and vegetables, milk and dairy products, all are great for raising mood. (5-1) And crunchy foods, like popcorn, are fabulous for making us feel happy.
M: Why is it so?
W: (5-2) The actual chewing mechanism raises neurotransmitter levels in the brain. So combining all these together creates wonderful combinations. For instance, potatoes with chili on top even. Those are great combinations.
M: OK. Then you got a very happy dinner, right?
W: Yes.
