| Between school, homework, sports, your afterschool job, and hanging out with friends, it may feel like there's no time for healthy eating. And when you do stop to eat, it's probably tempting to go the quick and easy route by grabbing a burger and fries, potato chips, or candy. Even if you take time to eat three meals a day, you may still feel hungry at times. This is natural-during teens, a person's body demands more nutrients to grow. What's the answer? Healthy snacks. Snacking on nutritious food can keep your energy level high and your mind alert without taking up a lot of your time. Snacks are a great way to satisfy that hunger and get all the vitamins and nutrients your body needs. But you need to pay attention to what you eat. Filling your face with a large order of fries after class may give you a temporary help, but a snack high in fat and calories will only slow you down in the long run. To keep energy levels going-and avoid weight gain-keep clear of foods with lots of simple carbohydrates (sugars) like candy bars or soda. Look for foods that contain complex carbohydrates like wholegrain breads and cereals and combine them with proteinrich snacks such as peanut butter or lowfat yogurt (酸奶) or cheese. Choosing healthy snacks means shopping smart. Be careful of the health claims on food packages. Just because something is "all natural" or "pure" doesn't necessarily mean that it's nutritious. For example, "all natural" juice drinks or sodas can be filled with sugar (which is, after all, a natural ingredient) but all that sugar means they'll be high in calories and give you little nutrition. A granola (麦片) bar is a good example of a snack that people think is healthy. Although granola bars can be a good source of certain vitamins and nutrients, many also contain a great deal of fat, including a particularly harmful type of fat called trans fat (反式脂肪酸). Check the Nutrition Facts label on the package to be sure. |
