Starch-free staple food
The staple foods without starch are bean products and fish.

There is no starch in it. Common staple foods contain some starch, such as corn, millet and rice. Eating a proper amount of starch-containing food during weight loss can supplement the energy needed by the body and generally does not cause fat accumulation in the body. When you lose weight, you should arrange your diet reasonably to avoid serious fat accumulation in your body. Eat regularly during weight loss.

Introduction of starch

Starch (amylum) is a kind of high molecular carbohydrate, which is a polysaccharide polymerized from glucose molecules. Its basic unit is α-D- glucopyranose, and there are two kinds of starch: amylose and amylopectin. The former is a spiral structure without branches; The latter consists of 24~30 glucose residues connected end to end by α- 1, 4- glycosidic bond, and the branch is α- 1, 6- glycosidic bond.

Starch is a kind of high molecular carbohydrate, and it is a polysaccharide composed of a single type of sugar unit. The basic building block of starch is α-D- glucopyranose, and the * * * valence polymer formed by removing water molecules from glucose is starch molecule. Starch belongs to polyglucose, and the molecular formula of free glucose is C6H 12O6.

The dehydrated glucose unit is C6H 10O5, so the starch molecule can be written as (C6H 10O5)n, where n is an indefinite number. The number of structural monomers (dehydrated glucose units) that make up starch molecules is called the degree of polymerization, which is expressed by DP.
