Sweet potatoes have many health benefits. Let’s explore them in detail below.
The fiber content in sweet potatoes are higher than that of common potatoes and they taste better too! When these two factors are combined with other minerals like magnesium, which is present in these root vegetables, it makes an excellent facilitator for digestion.

Sweet potatoes contain good amounts of complex starch, along with healthy vitamins, minerals, and proteins. Moreover, they are very easy to digest. Thus, they provide a lot of energy and are excellent bulk builders for people looking to gain weight.
People who have recently suffered from illnesses, or are self-conscious about being frail or abnormally thin should welcome this news about sweet potatoes since there are no associated side effects, which most of the synthetic bulk building dietary supplements have.
Sweet potatoes have anti-inflammatoryproperties and are primarily due to the presence of beta-carotene, anthocyanins, vitamin C, and magnesium. Beta-carotenes and anthocyanins are active bio-compounds that may exert antioxidative effects when consumed and thereby reduce oxidative stress and inflammation. Research and studieshave shown these compounds to possess potential suppressive anticancer activities and to promote immunity.  
Boost Immune System
Sweet potatoes are excellent immune system boosters that defend your body from a wide variety of conditions. As mentioned above, not only are they rich in antioxidant and vitamins, they are also rich in manganese, magnesium, and phosphorus.

Beta-carotene, magnesium, zinc, and vitamin B complex make sweet potatoes a highly important food source for managing arthritis.  The water in these tuberous vegetables are boiled can also be applied externally on joints to ease the associated pain of arthritis.
Research conducted on laboratory mice by Khalid Asadi et al.  from the Auckland Cancer Society Research Centre, New Zealand suggested purple sweet potato anthocyanin-rich diets helped reduce and inhibit tumor growth (Biomed Research International 2015). Chemoprevention trials are needed on humans to understand the anti-cancer properties of sweet potato.  Additionally, a study conducted by researchers from Kansas State University, US suggested that anthocyanin-enriched sweet potato may protect against colorectalcancer due to its antiproliferative abilities. 
Treat Stomach Ulcers
Research shows that a high fiber diet and a diet rich in vitamin C reduces the risk of developing stomach ulcers. These are good news because sweet potatoes are rich in fiber and vitamin C. They also contain B-complex vitamins, potassium, and calcium are all very effective in curing stomach ulcers.  Moreover, the roughage obtained from fiber prevents constipation and the resultant acid formation, thereby reducing the chance of ulcers.  Their anti-inflammatory and soothing properties also reduce the pain and inflammation of the ulcers.
Contrary to popular belief, sweet potatoes may be an acceptable food for diabetics. Although it is high carbohydrate and sugar, it is considered a low-glycemic food and have a lower glycemic index than regular white potatoes.  Cooking methods also alter the glycemic index of sweet potatoes. For example, boiled sweet potatoes have a lower glycemic index compared to roasted sweet potatoes. Of course, that does not mean that diabetics should eat them indiscriminately. The idea is that they can replace rice or white potatoes with sweet potatoes in their diet and cooking them by boiling rather than roasting.
The fiber or roughage present in sweet potatoes helps the body retain water.  This maintains water balance in the body, keeping you hydrated and your cells functioning efficiently.
