HealthAuthored by:Ashima Sharda MahindraUpdated Aug 8, 2026, 16:30 ISTSweet potatoes are rich in beta-carotene, fibre and antioxidants, supporting eye health, immunity and skin while offering versatile, nutritious meal options. Sweet potatoes are packed with fibreSweet potato - also known as shakarkandi- is a nutrient-rich root vegetable packed with beta-carotene, dietary fibre, complex carbohydrates, potassium and vitamin C. Its bright orange flesh is particularly rich in beta-carotene, a plant pigment that the body can convert into vitamin A. However, one important clarification is needed: the amount of vitamin A varies significantly by sweet potato variety and serving size. Orange-fleshed sweet potatoes are generally much richer in beta-carotene than white or purple varieties. Claims that every sweet potato provides 400 per cent of the daily vitamin A requirement can therefore be misleading. Also read:How much vitamin A is in a sweet potato?A medium orange-fleshed sweet potato can provide a substantial amount of vitamin A activity, largely in the form of beta-carotene. Vitamin A is essential for normal vision, immune function, skin health and cell growth. Unlike preformed vitamin A found in some animal foods and supplements, beta-carotene is a provitamin A carotenoid. The body converts it into vitamin A according to its needs. The colour of the sweet potato matters. Orange varieties generally contain the highest levels of beta-carotene, while purple varieties are better known for anthocyanins, antioxidant compounds that give them their deep colour. White-fleshed varieties contain considerably less beta-carotene. 5 health benefits of eating sweet potatoesSupports eye healthVitamin A plays a crucial role in normal vision, particularly in maintaining the retina and helping the eyes adapt to low-light conditions. Adequate vitamin A also supports the health of the cornea. Supports immune functionVitamin A is important for both the innate and adaptive immune systems. Eating beta-carotene-rich vegetables such as sweet potatoes can contribute to meeting nutritional requirements as part of a balanced diet. Promotes healthy skinVitamin A is involved in normal skin-cell growth and maintenance. Sweet potatoes also provide antioxidants that can help protect cells from oxidative stress. Provides fibre for digestive healthSweet potatoes contain dietary fibre, which supports bowel regularity and overall digestive health. Experts say boiled sweet potatoes can also provide resistant starch, depending on how they are prepared and cooled. Provide antioxidants and essential nutrientsBeyond beta-carotene, sweet potatoes provide potassium, vitamin C and other plant compounds. Different varieties offer different antioxidant profiles, making them a useful addition to a diverse diet. People with diabetes can also include sweet potatoes in appropriate portions as part of a balanced mealCan you get too much vitamin A from sweet potatoes?Eating beta-carotene-rich vegetables is not the same as taking high doses of preformed vitamin A. The body regulates the conversion of beta-carotene into vitamin A, and vitamin A toxicity from ordinary food sources such as sweet potatoes is uncommon. However, eating very large quantities of beta-carotene-rich foods can sometimes cause carotenemia, which may give the skin a yellow-orange tint. Excess fibre may also cause bloating or digestive discomfort. How should I eat a sweet potato?For a nutritious preparation, try steaming, boiling, roasting or baking sweet potatoes rather than deep-frying them. Pairing them with a small amount of healthy fat may improve absorption of fat-soluble carotenoids such as beta-carotene. People with diabetes can also include sweet potatoes in appropriate portions as part of a balanced meal. The cooking method, portion size, and what the sweet potato is eaten with can influence its impact on blood glucose.
