Sweet potatoes can offer you many health benefits. Here are some essential benefits of them.

1. Improves Gut Health

As the sweet potato has antioxidants and fiber, it is good for gut health. Sweet potatoes contain two types of fiber: soluble and insoluble. Your body cannot digest any type so that the fiber stays within your digestive tract and provides various intestinal-related health benefits. Some type of soluble fiber – called viscous fibers – absorbs water and softens your stool. At the same time, non-viscous, insoluble fibers absorb water and do not add aggregate.

Bacteria in your colon ferment some soluble and insoluble fibers, forming compounds called short-chain fatty acids, which fuel the cells of your intestinal lining and keep them healthy.

Fiber-rich foods containing 20–33 g per day are associated with an increased risk of colon cancer and regular bowel movements. The antioxidant properties in sweet potatoes can also provide intestinal benefits.

One Test-tube study has found that the antioxidants in purple sweet potatoes improve the growth of healthy intestinal bacteria, including some Bifidobacterium and Lactobacillus species.

High levels of these types of bacterias in the gut are associated with better intestinal health and lowers the risk of conditions such as irritable bowel syndrome (IPS) and infectious diarrhea.

2. Improving Insulin Sensitivity in Diabetes

In a 2008 study, researchers found that sweet potato juice with white skin has increased insulin sensitivity in patients with type 2 diabetes.

Previously, in 2000, laboratory rats ingested white-skinned sweet potatoes or an insulin-sensitive substance called troglitazone for eight weeks. Insulin resistance levels improved in those who ate sweet potatoes.

However, further studies in humans are needed to confirm these benefits. The sweet potato also has fiber in it. One study found that people who took high fiber had a lower risk of developing type 2 diabetes.

Serve around 124 grams (grams) of mashed sweet potatoes or half a cup to get about 2.5 grams of fiber. The 2015–2020 Dietary Guidelines for Americans suggest that 19 people and older took 22.4 grams to 33.6 grams of fiber per day, based on their age and gender.
