Health benefits of potatoes

Good source of anti-oxidants

Potatoes are a rich source of flavonoids, carotenoids, and phenolic acids. These compounds have excellent anti-oxidant properties and prevent cellular damage due to free radicals.

Control blood sugar

Potatoes contain resistant starch. As the name suggests, this starch is resistant to digestion. Therefore, it passes down to the large intestine where it becomes a source of nutrients for the healthy gut bacteria. This has been linked to promoting blood sugar control by reducing insulin resistance.

Promotes digestive health

The bacteria in the large intestine turn the resistant starch into short-chain fatty acids, most commonly, Butyrate. Butyrate prevents colon inflammation and reduces the risk of colon cancer.


People suffering from celiac disease or non-celiac gluten sensitivity are allergic to gluten protein present in wheat, rye, barley, and other foods. Potatoes are a nutrient-dense and gluten-free choice of food for gluten-sensitive people.
