The tubers of sweet potato are distinctively different from that of a potato. Sweet potato is from the bindweed or morning glory family while potato is from the nightshade family. Because of the etymological similarities between the two tubers, the common name of Ipomoea batatas is ‘sweet potato.’ Although, sweet potato is often, called ‘yam’ it will be a grave mistake if you think both are the same. These are botanically very different from the original yam, Dioscorea.
Sweet potatoes are available in different colors ranging from white to pale yellow to purple or red. The rich dark colors of sweet potatoes are, perhaps, due to the presence of abundant beta-carotene. While the yellow or white varieties are juicier, the red or purple ones boast rich aroma. The darker the shade, the richer is the aroma.
Sweet potatoes are damaged by frost and require plenty of sunshine and warm nights to grow and develop properly. According to data published by Food and Agricultural Organization in 2011, the world production of sweet potatoes was 106.5million tones led by China with a production of 81.7 million tones. India was the 7th largest producer with a whopping amount of 1.1 million tones. Another interesting fact about this particular herbaceous perennial vine is that, according to a study conducted by scientists of Ghent University and International Potato Center in 2015, sweet potatoes contain transgenes. This makes sweet potatoes the first known example of a naturally transgenic food crop.

Almost 80% of sweet potatoes are, filled with a protein called Sporamin. Sporamin, was discovered in the 1930s and was hailed as a unique protein with anti-cancer effects. Scientists have tested the effect of this protein on cancer cells in a petri dish and they found that it is very effective against leukemia cells. Tests were also, performed on human tongue cancer cells and it was, revealed that sporamin is very effective in mitigating the viability of such cancerous cells. When this protein was tested on colon cancer cells, it was found that sporamin not only diminishes the growth of colon cancer cells but also their migration and invasion. Sporamin is not completely, digested by the body and is found in the blood intact. Generally, when proteins leak into the blood they commence immune response. Sporamin ameliorate cancer survival without actually activating the host’s immune system.
