Health Benefits  

Improves digestion  

Sweet potatoes are rich in dietary fibre and are also well known for enhancing digestion and intestinal health. The high fibre content in sweet potatoes also aids in relieving constipation. Additionally, it possesses a significant amount of phytosterol, which protects the digestive system. Duodenal and stomach ulcers may be prevented and treated with it.

Sweet potatoes are beneficial for gut health as they contain soluble and insoluble fibre and antioxidants. Since neither form of fibre can be digested, they both stay in the digestive system and aid in preventing constipation. However, eating a diet high in fibre may also have the extra benefit of reducing the risk of colon cancer.

Sweet potatoes’ antioxidants support the growth of healthy gut bacteria, which may reduce the risk of IBS and infections.

Promotes weight loss  

Resistant starch (a carbohydrate that doesn’t get digested in the small intestine) makes up around 12% of the starch in sweet potatoes. Resistant starch could aid in weight loss and maintenance in several ways, including by increasing the release of peptides that let the body keep full and reducing the amount of fat stored in fat cells.  

They are regarded as a high-calorie food containing a lot of starch and have a reputation for being a vegetable that results in weight gain. However, that is untrue. Many people think of sweet potatoes as a healthier alternative to potatoes.  

Sweet potatoes are a good method to satiate the desire for carbohydrates because of their exquisite flavour and melt-in-the-mouth sugar flesh. They have a moderate amount of calories and are a good source of fibre and other nutrients that support weight loss and keep us healthy. One must include these sweet treats in the diet while trying to lose weight.

Helps manage Diabetes and blood pressure

Sweet potatoes have significant levels of carbohydrates and sugar. Sweet potatoes have a low glycaemic index. Unlike other starchy foods, sweet potatoes gradually release sugar into the bloodstream due to their low glycaemic index. This aids in lowering elevated blood sugar levels.

Sweet potatoes’ fibre content helps with diabetic management. According to studies, persons who eat more fibre may be less likely to acquire type 2 Diabetes. The amount of fibre in a half-cup of mashed sweet potatoes is roughly 2.5 mg.  

Some may perceive sweet potatoes as being overly starchy, but due to their high fibre content, they are a slow-burning starch and won’t cause blood sugar and insulin levels to surge.  

Boost immune system  

Sweet potatoes’ vibrant orange colour comes from beta carotene, which the body converts into vitamin A. Sweet potatoes provide more than 100% of the recommended daily intake of vitamin A, which is an essential component for a strong immune system.

The stomach plays a significant role in general health, and this same vitamin helps with it. Intestinal inflammation and antibody production are both increased by vitamin A deficiency. This important vitamin is added to foods to help lower inflammation in the gut and improve immune system function.

Nearly half of the daily vitamin C requirements are met by consuming one cup of cooked sweet potatoes. 400% of the recommended daily dose of vitamin A is provided in the same quantity.

Both nutrients are crucial for sustaining immunological function, which is especially crucial during cold and flu season. While taking vitamin C usually doesn’t actually prevent colds, it can lessen the duration and severity of a cold.

Aids eye health and vision  

Beta-carotene, a type of vitamin A, is high in sweet potatoes. Bright orange-fleshed vegetables typically contain this antioxidant. The body uses beta-carotene to make vitamin A, which is later used to develop light-detecting receptors in the eyes.

Oranges and sweet potatoes can help treat several vitamin A-related eye conditions, including xerophthalmia and cataracts. Also, purple sweet potatoes appear to be good for the eyes. Vitamin A improves night vision, lowers the risk of eye infections and prevents dry eyes.

Prevents the risk of cancer  

Purple-fleshed sweet potatoes are crucial in the battle against cancer. Sweet potatoes that are orange are rich in substances known as carotenoids because of their vibrant colour.  

Carotenoids serve as antioxidants and assist in controlling cell proliferation, which may suggest they lessen the risk of cancer. Sweet potatoes contain carotenoids that can help protect against cancer, including prostate cancer in men.

Antioxidant beta-carotene may aid in the prevention and risk reduction of colorectal cancer.
