What are the benefits of eating sweet potatoes?

The human body needs to consume all the nutrients that sweet potatoes contain. This is because, if we don’t consume the daily recommended amount of each of them, this can be harmful to our health. Although the content of these substances may vary among the different varieties that exist, the consumption of any of them is positive.

Aiding in healing

Because of their vitamin C content, sweet potatoes may help prevent bleeding and make wound healing more effective. This has to do with the fact that this compound acts on the healing process.

In fact, studies suggest that people used the yellow sweet potato in ancient times to treat diseases that have to do with this nutrient. Its vitamin C content combines with that of beta carotene to accelerate the action of fibroblasts.

Protecting cardiovascular health

If you eat them regularly and as part of a balanced diet, sweet potatoes are a food that has a cardio-protective effect. In other words, they prevent damage to the heart muscle and blood vessels. This is due to their vitamin B6 content, which helps slow down the hardening of arteries and other blood vessels.

Also, eating sweet potatoes lowers blood pressure because of their potassium content. This mineral has proven to have a positive effect among hypertensive patients, contrary to sodium.

Protecting the liver

The anthocyanins in sweet potatoes protect the liver function because they attenuate the changes that may occur. These compounds can prevent bleeding and cell inflammation, and even necrosis or death of this organ.

The liver is a tissue with multiple metabolic functions. Therefore, anthocyanins become indispensable in ensuring that internal processes develop properly.

Preventing the appearance of systemic inflammation

As we mentioned, sweet potatoes have antioxidant substances and their function is to prevent cell damage by free radicals. This reduces the inflammatory processes that take place constantly within our bodies.

In fact, the study “Foods with an anti-inflammatory effect” points out that these compounds could be oncological protectors. Therefore, they may reduce the development of breast, prostate, colon, and skin cancer. All these pathologies have to do with chronic inflammation.

Improving digestion

Because it has both soluble and insoluble dietary fiber, one of the benefits of sweet potatoes is that they help improve digestion. These components accelerate intestinal transit, preventing constipation and associated symptoms.

Also, fiber reduces the intestinal absorption of cholesterol and has a powerful satiating effect. In this way, it regulates blood sugar, which becomes key in diabetic feeding plans and the prevention of metabolic syndromes.
