Upon cooking, starch is transformed from an insoluble, difficult-to-digest granule into readily accessible glucose chains with very different nutritional and functional properties. [ 42 ] In current diets, highly processed foods are more easily digested and release more glucose in the small intestine—less starch reaches the large intestine ...
Amylose A is a parallel double-helix of linear chains of glucose. Amylose is made up of α(1→4) bound glucose molecules. The carbon atoms on glucose are numbered, starting at the aldehyde (C=O) carbon, so, in amylose, the 1-carbon on one glucose molecule is linked to the 4-carbon on the next glucose molecule (α(1→4) bonds).

The major sources of amylopectin of starch intake worldwide are the cereals such as rice, wheat, and maize, and the root vegetables potatoes and cassava. [25] Upon cooking, amylopectin in the starch is transformed into readily accessible glucose chains with very different nutritional and functional properties. [26]
Maltodextrin can be enzymatically derived from any starch, such as corn, potato, rice or cassava. [1] [4] [5] In the United States, this starch is usually corn; in Europe, it is common to use wheat. A food starch is boiled. The resulting paste is treated with a combination of acid and enzymes to produce maltodextrins. [6]
Glycogen is analogous to starch, a glucose polymer in plants, and is sometimes referred to as animal starch, [16] having a similar structure to amylopectin but more extensively branched and compact than starch. Glycogen is a polymer of α(1→4) glycosidic bonds linked with α(1→6)-linked branches.
Resistant starch is considered both a dietary fiber and a functional fiber, depending on whether it is naturally in foods or added. [ 51 ] [ 52 ] [ 53 ] Although the U.S. Institute of Medicine has defined total fiber as equal to functional fiber plus dietary fiber, [ 54 ] U.S. food labeling does not distinguish between them.
Creamy and rich in plant-based protein, healthy fats, and fiber, store-bought or homemade hummus adds a smooth texture and mild flavor that complements the other ingredients. Quinoa.
Dietary fiber is defined to be plant components that are not broken down by human digestive enzymes. [1] In the late 20th century, only lignin and some polysaccharides were known to satisfy this definition, but in the early 21st century, resistant starch and oligosaccharides were included as dietary fiber components.
