17．Are you having too much salt？You might not think so．But people in China eat on average （平均） about 12 grams of salt each day，that is much higher than the 6 grams suggested by the World Health Organization．Many people in China don't realize they are eating too much salt，because about 75% of the salt we eat is already in the food we buy，such as bread，soups and sausages．A small amount（數(shù)量） of salt is important for good health because our bodies need it．But past studies have found that people who eat more salt than they need may have high blood pressure．Eating too much salt has also been connected with other conditions，like a heart problem．
    If you want to cut down on salt，here are two tips：
Cut back on（減低） high salt foods．
   Most foods contain（包含） some salt．But some foods such as cheese，salted fish and chips are almost always high in salt because of the way they are made．You can still enjoy them，but try to have these in smaller amounts，or eat them less often．
Choose reduced salt bread andbreakfast cereals（谷物）．
   Bread and breakfast cereals are main source（來源）of salt in the diet．For these foods，there can be a really big difference between different types and brands（品牌）．So next time you're shopping，take the time to compare the salt levels on a few similar products．And always try to choose the ones lower in salt．
ProblemsMany people don't realize about three （76）fourths of the salt we eat is already in the food we buy．
Eating too much salt can （77）have high blood pressure and other diseases．
AdviceEat 6 grams of （78）salt each day to keep fit．
For a healthier life，we should eat （79）less salted food．
（80）Stop adding too much salt to cooking and at table．
