SWEET POTATO AND YAM FACTS

Sweet potatoes contain an enzyme that converts most of its starches into sugars as the potato matures
This sweetness continues to increase during storage and when you cook them

Canned sweet potatoes are often labeled yams

Yams derive their name from the Senegalese word fiam, meaning “to eat
” Sweet potatoes are a Native American plant that was the main source of nourishment for early homesteaders and for soldiers during the Revolutionary War
These tuberous roots are among the most nutritious vegetables and are excellent sources of the antioxidants beta-carotine and vitamin C
There are two varieties of sweet potatoes: the pale yellow with a dry flesh and the dark orange with a moist flesh
The dark-orange variety is plumper in shape and somewhat sweeter and moister than the yellow variety
Because most of the nutrients in sweet potatoes are next to the skin, cook them whole whenever possible
Yams and sweet potatoes are very similar and often confused for one another, but they aren’t the same
However, they are interchangeable in most recipes
While sweet potatoes and yams are very healthy if simply cooked, many recipes—such as candied yams or sweet potato fries—pile on butter, sugar, and oil
So avoid these add-ons to get the most nutrition from these sweet tubers

The famous Nurses’ Health Study at Harvard Medical School found that women who ate lots of foods rich in beta-carotene, such as sweet potatoes, reduced their risk of breast cancer by as much as 25%

Even if you cut them away, decayed spots may have already caused the whole vegetable to take on an unpleasant flavor

Storing Tips

5°C) place such as a cellar, pantry, or garage
They will keep here for a month or longer

Don’t store them in the refrigerator, because they may develop a hard core and a bad taste

If you keep them at normal room temperature, you should use them within a week of purchase

Don’t wash them until you’re ready to cook them
The moisture from washing will make them spoil faster
