Health Benefits of Sweet Potato

Sweet potatoes are superfoods because of their high level of nutrition. Here’s a closer look at the advantages and health benefits of eating sweet potatoes:

Good for Eye Health

Sweet potatoes are a good source of beta-carotene, a type of vitamin A that helps treat eye conditions brought on by a deficiency of the vitamin. Orange sweet potatoes are the primary source of the antioxidant beta-carotene. In addition to improving vision, this antioxidant aids in the treatment of xerophthalmia and cataracts. According to Food & Nutrition Research research, purple sweet potatoes have anthocyanins, a particular class of antioxidants that have eye-beneficial properties.

Improves Digestion

Dietary fibre from sweet potatoes naturally helps with digestion and gastrointestinal wellness. Additionally, it has a high concentration of phytosterols, a type of plant sterol that protects the digestive tract and prevents constipation. Sweet potato phytosterols may be effective in the prevention and treatment of duodenal and stomach ulcers, especially those caused by NSAIDs (nonsteroidal anti-inflammatory drugs like ibuprofen).

Improves Heart Health

Antioxidants and fibres aid in lowering the risk of cardiovascular diseases. Sweet potatoes are helpful in enhancing heart health because they are high in antioxidants and fibre. Additionally, purple sweet potatoes’ anthocyanin content reduces the risk of coronary heart disease.

Aids Weight Loss 

Sweet potatoes are an excellent source of resistant starch, a filling, fibre-like carbohydrate that the body is unable to absorb or digest. Resistant starch stimulates the release of peptides, which signal to the body that you are full. Additionally, resistant starch lowers the body’s fat storage capacity.

Improves Skin and Hair Health

Sweet potato extract is beneficial for skin and hair because it contains a variety of vitamins, including antioxidants, vitamins A, C, and E. While vitamin E supports healthy skin and hair, vitamin C increases the production of collagen, which naturally improves skin texture. The anti-inflammatory qualities of vitamin C also help prevent acne and skin infections.

Regulate Blood Sugar Levels

Despite having a high starch and sugar content, sweet potatoes have a low glycemic index, which implies that, in contrast to other starchy foods, their sugar content gets released gradually into the bloodstream. The gradual breakdown of sugar in the body reduces the chance of high blood sugar levels.

A higher-fibre diet lowers the risk of type 2 diabetes. Therefore, sweet potatoes’ high fibre content helps to manage diabetes. In fact, one cup of baked sweet potato offers approximately three grams of fibre.

Summary

Sweet potatoes have a number of health advantages that come with including them in a daily diet. Antioxidants are abundant in sweet potatoes, especially in the purple and orange types. Antioxidants lower the chances of cancer, heart disease, and ageing by combating free radicals in the human body. Sweet potatoes contain both soluble and insoluble fibres. The gut health benefits greatly from both forms of fibre. Sweet potatoes’ orange hue is a result of their high beta-carotene content. The body uses this beta-carotene to produce vitamin A, which is beneficial to vision. Sweet potatoes stabilise blood sugar levels and increase insulin sensitivity. They are also an excellent addition to weight-loss diets due to the presence of resistant starch.  

Ways to Eat Sweet Potato

Sweet potatoes are highly versatile due to their mildly sweet and nutty flavour, which pairs well with a variety of recipes. One can add sweet potatoes to regular meals in the following ways:

Salads and Soups

Add cooked, diced, sweet potatoes to any soups or salads of choice for a nutritious addition to the meal.

Quick Snack

Potential Side Effects of Sweet Potato

Besides several health benefits, sweet potatoes also have some potential side effects. Here are some possible side effects to be wary of:

  • Sweet potatoes are rich in potassium, and when taken with medications that increase potassium levels in the body, such as beta-blockers, they may cause problems related to excessive potassium intake levels in the body.
  • People with kidney problems must avoid eating sweet potatoes because an improper-functioning kidney cannot remove potassium from their body, causing high potassium levels that can be harmful to them. Sweet potatoes contain high amounts of oxalates, which could increase calcium-oxalate kidney stones risk. 
  • Sweet potatoes contain beta-carotene, and their excessive consumption causes hypervitaminosis A (vitamin A toxicity). This excess vitamin A accumulates in the liver, and the colour of the skin and nails may turn orange.
  • Additionally, sweet potatoes are rich in carbohydrates. Therefore, those on a carbohydrate restriction diet should avoid overindulging in them.

Summary

Sweet potatoes contain oxalates, which are substances that bind calcium and other minerals. A diet high in oxalates may result in kidney stones. If you currently have kidney stones or are at increased risk of getting them, you should limit the amount of foods high in oxalate. Overindulging in sweet potatoes is not recommended for people on a carb-restriction diet or using drugs that raise potassium levels in the body. Because sweet potatoes contain beta-carotene, consuming too much of them can lead to hypervitaminosis A or vitamin A poisoning. When the liver absorbs too much vitamin A, the skin and nails may become orange in colour.
