Grain refers to the general term for various plant seeds in cooking foods, and can also be generally referred to as "cereals". Food crops are rich in nutrients, mainly including protein, vitamins, dietary fiber, fat, starch, etc. Food in a narrow sense only refers to the seeds of gramineous crops, while food in a broad sense also includes the edible roots or stems of potatoes and other plants. The nutrients contained in grain are mainly sugars (mainly starch), followed by protein.
