生活百科：健康饮食系列之二——怎么吃更健康

STEP 1 步骤1
Eat whole, unprocessed（未加工） foods whenever possible. This means fresh or frozen fruits instead of canned, whole grains（全谷物类） instead of enriched flour, brown rice instead of white rice, and as little fast food as possible.

Avoid 'low-fat' or 'zero-calorie' processed foods, as they typically have more sugar and salt. Refining grains also removes bran, which contains most of the vitamins, minerals, and fiber.

STEP 2 步骤2
Follow the FDA’s（食品及药物管理局） recommendations to eat at least five servings of fruits and vegetables a day. Try sprinkling berries in your cereal, drinking a fruit smoothie or juice, and adding extra veggies to your pasta sauce, pizza, casseroles, and even sandwiches.

An official serving size is: a medium piece of fruit, a ½ cup of chopped fruit, ¾ cup of pure juice, a ¼ cup of dried fruit, a ½ cup raw or cooked vegetables, or a cup of leafy vegetables.

STEP 3 步骤3
Pay attention to what, how much, and how often you eat. Absentminded eating is one of the greatest threats to successful weight management and long-term health.

Don’t multitask when eating. You’ll often stuff your face with nutritionally poor foods that are convenient but not healthy.

STEP 4 步骤4
Try to drink 64 ounces of non-caffeinated（不含咖啡因的） fluids every day—the majority of which should be plain, pure water. A glass with every meal will help your digestion, keep you full, and help your mood—and if you drink it before eating, it can stave off hunger pangs.

STEP 5 步骤5
Eat fish twice a week: it’s packed with top-quality protein, as well as omega-3 and omega-6 fatty acids that can protect your heart and brain from damage and disease.

STEP 6 步骤6
It’s okay to splurge and eat something less-than-healthy now and then, just be sure to watch out how much and how often.
