问题     Sodium(钠)is a key component of salt. Eating too much of it can【C1】______to high blood pressure, a major risk for most people as they age because it can lead to heart disease and other health problems. But cutting sodium from the diet is difficult, mainly because people often don’t know it’s there. More than three-quarters of the sodium people【C2】______ comes from processed and restaurant foods. And much of the sodium we eat is in foods that don’t【C3】______taste salty, like packaged bread and chicken dishes. Salt is the latest front in the battle to get Americans to eat a healthier diet.【C4】______efforts have focused on cutting down on sugar, to fight against obesity, and reducing fat, for a healthier heart.

    The best way to reduce salt is to cut back on processed and restaurant foods, eat fresh produce, and reduce portion sizes. Nutritionists【C8】______eating whole grain instead of bread—a single slice of packaged bread can contain 150 mgs to 200 mgs or more of sodium. Cut back gradually, so your palate(味觉)adjusts to a less salty taste. When you do buy artifactitious(人工制品的)foods, look for【C9】______witn less than 300 mgs of sodium per serving, or no more than one milligram of sodium per calorie of food, advised the Harvard School of Public Health, which has on its website 25 sodium-reduction【C10】______developed with the Culinary Institute of America.
