Health Benefits of Sweet Potatoes

Listed below are a few sweet potato benefits in pregnancy.

1. Helps in the Proper Growth of the Foetus

Doctors recommend that pregnant women eat foods rich in Vitamin A as they need at least 800 micrograms of Vitamin A daily. This can be obtained from less than half a cup of baked sweet potato. Vitamin A is crucial in foetal development as it helps in the growth of the organs like the heart, lungs, liver, blood, kidneys, and so on.

2. Prevents Constipation

Sweet potatoes are a good source of fibre, which is an important nutrient during pregnancy. Pregnant women often complain of constipation, which is a common problem during pregnancy. Your diet should comprise of around 30 grams of daily fibre – a third of this can be obtained from a single cup of sweet potatoes.

3. Helps in the Brain Development of the Foetus

Pyridoxine, also called Vitamin B6, is essential for the formation of a functioning brain and nervous system in the foetus. It is needed to produce blood and has been known to prevent nausea in pregnant women. A cup of sweet potatoes will have around a third of the required daily amount of pyridoxine.

4. Helps in the Bone Development of the Foetus

During pregnancy, a woman’s diet should include around 90 mg of Vitamin C per day. A single cup of sweet potato can provide at least a third of that amount. Vitamin C promotes enzyme activity, bone and tendon growth, skin development and so on. It also speeds up the absorption of iron, which is required for the formation of red blood cells. A cup of sweet potatoes can also provide your body with nearly half the amount of manganese required per day. Manganese is a rare mineral which also helps in the development of bones and cartilage of the foetus.

5. Cures Morning Sickness

Sweet potatoes help form red blood cells in the body as they are rich in Vitamin B6, which also helps relieve morning sickness.

6. Prevents Hypertension

Sweet potatoes are rich in potassium, that regulates the blood pressure. In pregnancy, the blood volume increases by around 50% and can take a toll on the electrolytic balance and blood pressure of the expecting woman.
