.Have you ever noticed that you feel happier and more relaxed after you eat bread, pasta or fruit? Do you find that you are more energetic and awake after eating yogurt or beans? These things are not accidents. Food affects how we feel more than we may think. Scientists researching food and its effect on our moods are beginning to understand that we can influence our feelings with what we eat.

There are chemicals in our brains that control our moods. One of the most basic of these is serotonin (血清素) , one of the most commonly recognized. When serotonin levels increase, we feel more relaxed and happy; when the levels decrease, we feel unhappier.

Proteins (蛋白质) found in nuts, vegetables, tofu and some milk products contain a chemical that makes us feel more awake and energetic.

Another chemical that can easily affect our mood is caffeine (咖啡因). Caffeine, which is found in coffee, chocolate and many types of tea, is perhaps the worst thing you can have when you are feeling stressed. Yet coffee or chocolate are often the first things people think of eating when they are under pressure. Caffeine and sugar can reduce your blood sugar level, which changes your brain chemistry and vitamin levels, making you feel even more stressed.

Of course, enjoying a nice meal with friends, whatever we eat, can also affect how you feel. It is important not to worry about eating the right foods to control your mood. Most importantly, though, remember the old rule: try to eat different foods, and do not eat too much!
