A healthy eating style is like a puzzle with many parts. Each part—or food—is different. Some foods may have more fat, sugar or salt while others may have more vitamins or fiber. There is a place for all these foods. What makes a diet good or bad is how foods fit together. Balancing your choices is important. Fit in a higher-fat food, like pepperoni pizza, at dinner by choosing lower-fat foods at other meals. And don’t forget about moderation. If two pieces of pizza fill you up, don’t eat a third.

Balance your food choices—don’t eat too much of one thing.

You don’t have to give up foods like hamburgers, french fries and ice cream to eat healthfully. You just have to be smart about how often and how much of them you eat. Your body needs nutrients like protein, carbohydrates, fat and many different vitamins and minerals such as vitamins C and A, iron and calcium from a variety of foods. Balancing food choices from the Food Guide Pyramid and checking out the Nutrition Facts Panel on food labels will help you to get all these nutrients.

Humor is infectious. The sound of roaring laughter is far more contagious than any cough, sniffle, or sneeze. When laughter is shared, it binds people together and increases happiness and intimacy. In addition to the domino effect of joy and amusement, laughter also triggers healthy physical changes in the body. Humor and laughter strengthen your immune system, boost your energy, diminish pain, and protect you from the damaging effects of stress. Best of all, this priceless medicine is fun, free, and easy to use.

Snacks are a great way to refuel. Choose snacks from different food groups—a glass of low-fat milk and a few graham crackers, an apple or celery sticks with peanut butter and raisins, or some dry cereal. If you eat smart at other meals, cookies, chips and candy are OK for occasional snacking.

It’s easy to fit physical activities into your daily routine. Walk, bike or jog to see friends. Take a 10-minute activity break every hour while you read, do homework or watch TV. Climb stairs instead of taking an escalator or elevator. Try to do these things for a total of 30 minutes every day.

Breakfast fills your “empty tank” to get you going after a long night without food. And it can help you do better all day. Easy to prepare breakfasts include cold cereal with fruit and low-fat milk, whole-wheat toast with peanut butter, yogurt with fruit, whole-grain waffles or even last night’s pizza!
