生活百科：健康飲食系列之十——如何選擇健康的零食

STEP 1 Count calories 計(jì)算卡路里

Watch the numbers: A snack shouldn't have more than 200 calories.

STEP 2 Follow the 35-10-35 rule 遵循35-10-35規(guī)則

Choose an item that gets no more than 35 percent of its calories from fat, no more than 10 percent of its calories from saturated fat, and is no more than 35 percent sugar by weight. Fruits, cheese, nuts, and seeds are exempt.

Beware of snacks marked "fat-free." They're often loaded with sugar or sodium.

STEP 3 Include protein 加入蛋白

Make sure the snack includes protein, which keeps you feeling full longer than carbohydrates alone.

STEP 4 Make it high fiber 做高纖維食物

Choose cereal and protein bars that are high in fiber – at least 3 grams per serving. Fiber helps the body digest food and metabolize fat.

STEP 5 Watch the sodium 觀察鈉含量

Take it easy on the salt, an excess of which can lead to high blood pressure. Stick to snacks that provide less than 450 milligrams of sodium per serving.

STEP 6 Choose protein bars carefully 仔細(xì)挑選蛋白

Avoid protein bars that have more than 15 grams of sugar or 5 grams of fat – they're not much better than candy bars.

STEP 7 Watch your diet 注重均衡

Factor in the calorie counts of your snacks once you sit down to a regular meal. Even the healthiest snacks can add pounds if you don't compensate for them elsewhere!

In one survey, women listed chips as their number one workplace snack food, followed by chocolate and candy bars.
