Health benefits of sweet potato
- Improves gut health
Sweet potatoes have fiber and antioxidants which provide gut-related health benefits. They help in softening stools and reduce the risk of colon cancer, also improving bowel movement.
The soluble and insoluble fibers can also be fermented by the bacteria in your colon, creating compounds called short-chain fatty acids.
These short-chain fatty acids fuel the cells of your intestinal lining and keep them healthy and strong.
- Cancer-fighting properties
Sweet potatoes offer various antioxidants, which may help protect against certain types of cancers.
Anthocyanins are a particular group of antioxidants found in purple sweet potatoes which reduces the risk of colon, bladder, and breast cancer, according to research.
Extracts of orange sweet potatoes and sweet potato peels have also been found to have anti-cancer properties in test-tube studies. However, human trials are yet to be done to confirm the effects.
- Healthy vision and eyesight
Sweet potatoes are a rich source of beta carotene which gets converted to Vitamin A inside the body and are used to form the light-detecting eye receptors.
Severe vitamin A deficiency is a concern in developing countries and can lead to a special type of blindness known as xerophthalmia.
Eating beta carotene-rich foods like sweet potatoes can help in preventing this problem and keep up a good vision.
- Enhancing brain function
Consuming purple sweet potatoes may improve brain function. According to studies, the anthocyanins present can reduce inflammation and can prevent free radical damage
No studies have been done to test these effects in humans, but in general, diets rich in fruits, vegetables, and antioxidants are associated with a 13% lower risk of mental decline and dementia.
- Strengthen the immune system
Orange-fleshed sweet potatoes are one of the richest natural sources of beta-carotene converting to Vitamin A in the body, making it a great choice for a healthy immune system.
Studies have shown that vitamin A deficiency increases gut inflammation and reduces the ability of your immune system to respond properly to foreign agents or pathogens.
As sweet potato is a rich source of beta carotene, it can be a good choice to maintain immunity. However, researchers are yet to clarify this point.
- Adequate hydration
Sweet potatoes contain a rich amount of fiber which helps in retaining water in the body, thus making them a fit choice for adequate hydration.
The water content in sweet potatoes is also relatively high so you can consume them in order to maintain a proper fluid balance, apart from energy drinks or other natural electrolyte drinks.
