Why do you need starchy foods? Starchy foods are a good source of energy and the main source of a range of nutrients in our diet. As well as starch, they contain fibre, calcium, iron and B vitamins. Some people think starchy foods are fattening, but gram for gram they contain fewer than half the calories of fat.

How does starch help the body?

Starchy foods are a suitable source of energy because of their high carbohydrate content. When a person's body digests starch, it breaks down into glucose molecules. This glucose enters the bloodstream and powers nearly every cell in the body, including the organs, muscles, and brain.

What is the importance of starch in plants?

Biological Importance

All plant seeds and tubers contain starch which is predominantly present as amylose and amylopectin. Plants use starch as a way to store excess glucose, and thus also use starch as food via the mitochondrial oxidative phosphorylation during at night or when photosynthesis is unlikely.
