Is a sweet potato a potato?

Both sweet potatoes and regular potatoes are root vegetables, and they have their similarities with each other, but the difference is their shape and nutrition.

And I’m afraid sweet potatoes and potatoes cannot be called the same. Even though they have some similarities, they belong to different plant families. 

Different families

Sweet potatoes are from the Convolvulaceae family and are known as the morning glory family. In contrast, potatoes are from the Solanaceae family, also known as the nightshade family. Both plants are native to different parts of Central and South America and are now found worldwide.

Sweet potatoes grow underground, attached to the roots of the potato plant. Although sweet potatoes and regular potatoes grow similarly, they are different vegetables from two different plant families and should not be considered vegetables from the same plant kingdom.

What is healthier, potato or sweet potato?

Even though both sweet potatoes and regular potatoes sound similar, they are entirely different when being healthier.

Generally, sweet potatoes are considered healthier than regular potatoes, but we eat more regular potatoes instead of sweet potatoes. Sweet potatoes are indeed rich in nutrients, vitamins, and minerals.

There are many reasons why sweet potatoes are healthier than regular potatoes, and they are mentioned below:

Sweet potatoes have a higher amount of vitamin A which contributes to your health.

#2- Antioxidants

Antioxidants are a must for the human body since antioxidants help the body fight different diseases such as cancer, brain and heart diseases. One of the best sources of antioxidants is potatoes and sweet potatoes. Sweet potatoes are rich in antioxidants and other vital nutrients.

This is where sweet potatoes take the lead over potatoes. Glycemic index (GI) is a value that shows how fast food causes an increase in blood glucose levels.

It is usually measured on a scale between 0 to 100 to show how quickly a food can increase the blood sugar level. A boiled potato has a GI of 78, while a boiled sweet potato has a GI of 63.

This proves that sweet potatoes are less likely to break down to cause a sudden blood sugar rise. It is important to consider eating foods with a glycemic index since too much can cause a sudden spike in blood sugar level and low intake can lower blood sugar and aid in weight loss.
