Cereals should not only be limited to rice, but can be supplied alternately with all kinds of pasta, and coarse grains such as potatoes should be added appropriately to enrich staple foods;
谷类食物不应仅仅局限于大米，可以与各类面食交替供应，并适量增加薯类等粗粮，以丰富主食；

The proportion of fish and shrimp should be increased in the supply of meat. The protein of fish and shrimp is easier to digest and absorb than that of livestock, and the fat content of fish and shrimp is lower than that of livestock, and the fat is mostly unsaturated fatty acid, which is conducive to the cardiovascular and cerebrovascular health of the elderly.
