More About Sweet Potato
Sweet potato probably originated in Central or South America, somewhere between 5000 - 10000 years ago. Today, it is cultivated in all warm and tropical regions worldwide, wherever there is enough water. It grows best in abundant sunshine and warm night temperatures. The plant does not tolerate frost.
Sweet potato can even grow in poor soil, is very resistant to pests and rarely needs pesticide sprays. However, it is extremely sensitive to aluminium toxicity and needs application of lime at planting time in poor soils.
Varieties Of Sweet Potato Plants
Uses Of Sweet Potato
The tuberous roots are mostly eaten. In some areas, however, the shoots and leaves are also consumed as a vegetable.
Some non-culinary uses of sweet potato include :
- Making dyes for dyeing cloth.
- As an animal fodder.
- As ornamental plants in gardens. When grown in home aquariums, it removes toxic wastes like ammonia and nitrates that the fish produce, thus improving the water quality and improving the living conditions for these aquatic creatures. Fish find the well spread out roots a good habitation space.
Difference Between Sweet Potatoes And Yams
Sweet potatoes are from the morning glory family. The seed has 2 cotyledons. Botanically, they belong to the family Convolvulaceae and are native to South and Central America.
Yams are closely related to the lilies and grasses. Botanically, they belong to the family Dioscoreaceae. The seed has a single cotyledon. They are native to Africa and Asia.

Useful Information About Sweet Potatoes
Consume about 1 tbsp of oil like olive oil, which provides about 3.5 gms fat, along with sweet potatoes to significantly increase the absorption of beta carotene. Research has shown that about 3 to 5 gms of fat aids in maximizing the beta carotene absorption from sweet potatoes.
Steaming and boiling sweet potatoes afford the maximum nutritional benefits. Also, boiling lowers the glycemic index which leads to better management of blood sugar levels.
Steaming for only 2 minutes deactivates the enzymes that would have otherwise broken down the anthocyanins and caused a loss in their antioxidant and anti-inflammatory benefits. Steaming for 7 minutes maximizes their nutritional value and flavour.

@ Lady Guinevere - I'm glad you like the info. As far back as I can remember I always had sweet potatoes as a kid, boiled or baked. I too love them. I'm sorry I was away on a holiday for a few days hence the delay in replying but I did get both your comments.
Appreciate your sparing time to read and comment. Also for sharing. Thanks.
@ ib - coconut oil though has saturated fats is comprised of healthy saturated fats more than half of them being lauric acid that along with the fats being medium chain fatty acids, give coconut oil its many amazing health benefits. Also2/3 of these fats are more stable to heat as compared to the mono saturated fats in olive oil.

Patricia Scott from North Central Florida on January 26, 2013:
Oh, rajan jolly, you have done such a lovely job of giving us information on the sweet potato. It is one of my favorite foods. One reason it is a favorite is because in addition to being healthful it is so versatile. There are so many ways to prepare it that it is a great food to serve to complement many other foods.
Sending you Angels this morning....:) ps

Although it is sometimes called a yam in North America, the sweet potato does not belong to the yam family, it is not closely related to the common potato either. But I wonder why it is not as much popular as the common potato! Thank you for sharing such vital information.
Mary Craig from New York on January 23, 2013:
Rajan, you continue to outdo yourself. I start reading thinking I know everything about sweet potatoes but as usual, you teach me I do not! How wonderful and beneficial your hubs are ....thank you for trying to keep us healthy.

ib radmasters from Southern California on January 21, 2013:
Thanks for your answer
ib - I would have preferred coconut oil rather than olive oil if oil needed to be heated. It's safer and healthier. Appreciate the read and concern.
What temperature would you use to bake with either coconut oil or olive oil? And a lot of cooking uses olive oil.
Debra Allen from West By God on January 21, 2013:
Wow that is a lot of useful information there. I love sweet potatoes. I usually buy them from the Farm Market and then take them home cut them up and freeze them for later use. I didn't know they were that good for the skin. I think I will be eating more of them. I also didn't know that the darker color is sweeter. Now to find those and I will be set. Thanks for this very informative article! I rate it up and will share it.

@ Au fait - Hope you try out the sweet potato pancake recipe. Thanks for stopping by and sharing.
@ Rebecca - Yams are much larger than sweet potatoes as well as they have a thicker skin. I hope the differentiation is clearer. Hope you too try the pancakes too. Thanks for voting and reading.
Rebecca Mealey from Northeastern Georgia, USA on January 21, 2013:
Thanks, rajan. I always thought sweet potatoes and yams were the same thing. I love sweet potatoes, yams too, I suppose. I make sweet potato fries frequently. I must try the pancakes. Rated 5 stars.
C E Clark from North Texas on January 21, 2013:

Hello Rajan! Another wonderful hub about our health and our power to stay healthy with good choices and the power of knowledge!

Voted up and interesting. Love sweet potatoes but we can't always get them here and if we do they are not good quality. However I will keep a look out for them at market because I haven't had them for a long time now and you got me hungry. Great info and passing this on.
Wilbart26 on January 19, 2013:
I never tried sweet potatoes in my whole life... I guess it's a sad part for me, however, it's not yet late, I better look for one later and eat a bunch of sweet potatoes... This hub is very informative. Thanks for sharing. keep us educated.
Paul Richard Kuehn from Udorn City, Thailand on January 19, 2013:
This is a very useful and interesting hub about sweet potatoes. Thank you for clarifying the difference between yams and sweet potatoes. I originally thought they were both basically the same. I never ate sweet potatoes much as a kid, but after I moved to Taiwan in the 70s I started to eat yams which I could buy on the street. They were roasted over coals and absolutely delicious. In the Taiwanese dialect of Chinese they were called "hanji". Voted up and sharing with followers and on Facebook. Also Pinning.

Great hub on Sweet potatoes! As a family we have tried to incorporate more sweet potatoes into our regular meals so always looking for new ideas. Love all the various colors, have not tried them yet but now I am inspired!
Stephanie Henkel from USA on January 19, 2013:
Sweet potatoes are a favorite vegetable of my husband and myself. Though I like to make candied sweet potatoes (not very diet friendly!) at Thanksgiving, we also like them just baked in their skins. Thanks for the great nutritional information...it's good to know that they are so good for us! Voted up and shared!
Hawaiian Odysseus from Southeast Washington state on January 19, 2013:
Professionally researched, written, and presented, with great complementary photo and video media! Rajan, as we say in America--You Da Man! Reading this hub brought back memories of my father growing sweet potatoes and other vegetables in the somewhat sandy soil (because our home was just a few hundred yards away from the ocean). Yes, we DID eat the shoots as well. My mother made a miso (soy paste) sauce, and we ate the shoots like a salad. Sweet potatoes are very tasty, and now I know that they're very nutritious as well. Thank you for ever reminding me that the diet of the islands was jam-packed with nutritional goodness. Voted up and more and sharing!
Thelma Alberts from Germany on January 19, 2013:
Wow! I did not know that this favorite food of mine has a lot of health benefits. I love eating sweet potato leaves salad as well. Thanks for sharing rajan. This is a very informative hub. Voted up and shared. Happy weekend!
Shining Irish Eyes from Upstate, New York on January 19, 2013:
Rajan - There was a time when I was not so fond of sweet potatoes. Then my Dad tried a new recipe on me and I was in heaven!!!
I have now acquired quite an affinity for sweet potatoes and am thrilled to know one of my favorite choices is equally beneficial for me.
I found the non-edible uses of sweet potatoes fascinating as well.
carol stanley from Arizona on January 19, 2013:
I look at the sweet potatoes every time I am in the grocery store. They are not big favorites with us, but I am thinking of baking them like french fries...Thanks for all the useful information and I am spirited on to try the potatoes. Voting up+++and pinning.
