According to a study from Harvard's T.H. Chan School of Public Health, many Americans get only about half the fiber they need daily, much of which is an insoluble carbohydrate called cellulose. This complex carbohydrate is a critical component of a healthy diet, even though the human body cannot digest or absorb it.

Globally, starch serves as a major source of dietary calories, with more than 80% coming from plants. Native starch is a polymeric carbohydrate produced by plants for energy storage, consisting of two primary glucose polymers: amylose and amylopectin. These components are what native starch is made of, and their specific ratio and structural arrangement dictate the starch's functional properties.

Despite what some might mistakenly assume, starch is unequivocally a polysaccharide, a fact consistently confirmed by biochemical science. As a core component of plant energy storage, its polymeric nature is fundamental to its biological function and nutritional role.

Every green plant produces a white, tasteless, and odorless powder known as starch to store excess energy from photosynthesis. This complex carbohydrate, often found in staples like potatoes, rice, and corn, is not a single uniform substance but a composition of two distinct polysaccharides: amylose and amylopectin. Their ratio and structure are key to understanding starch's versatile properties in both food and industry.

According to the American Diabetes Association, starchy foods like grains, potatoes, and beans provide essential energy as they are the body’s preferred fuel source. But at its core, what is starch in a very short answer? It is a complex carbohydrate, or polysaccharide, produced by most green plants to store energy.

According to the World Health Organization, carbohydrates—including starch—are a crucial part of a healthy diet, providing the body with energy. This makes understanding the chemical composition of this common polysaccharide important, especially when considering the question: what does starch contain?
