Dietribes: The Sweet Potato


I was averse to the idea of the sweet potato for many years before recently giving it another shot. But after one glorious, butter and cinnamon laden mouthful ... BAM! It's now one my favorite foods, whether baked, roasted or in fry form. Here are some facts about this orange delight, an incredibly healthy food, and a great way to get fiber, protein, vitamins A and C, iron and calcium.

"¢ The sweet potato's earliest cultivation is thought to date back to around 750 BC in South America. Slowly making its way up through Central America and eventually into the awareness of explorers such as Christopher Columbus, the sweet potato crossed continents and became a favorite among Elizabethan-era English, who enjoyed its natural sweetness in times of sugar scarcity.

"¢ Speaking of which, here is a discussion of Shakespeare's mention of the tasty tater in the Merry Wives of Windsor.

Though Vardaman, Mississippi, claims to be the Sweet Potato Capital of the World, approximately 90% of the worlds' crop is grown in Asia, and is the 6th principal world food crop (more facts here).

"¢ According to History of Food, "The people of the Antilles make a drink from the sweet potato, ouycou, from a Caribbean Indian recipe. The Empress Josephine tried to bring the sweet potato back into fashion "“ Louis XV had been very fond of it "“ but its 'exotic' flavour put off the general public, who preferred ordinary and more plebeian Potato."

"¢ Forget the peanut. George Washington Carver came up with 118 different ways of using Sweet Potatoes, including as starch, tapioca, mock coconuts, molasses, breakfast foods, flour, ink and synthetic rubber. Additionally, the ocarina is often referred to as a sweet potato because of its shape and "sweet" sound. (Gamer Fact: the ocarina is the instrument played by Link in the Legend of Zelda).

"¢ What is the difference between a Sweet Potato and a Yam? They are members of different botanical families, but are frequently confused. For a start, Yams have more starch and less sugar than sweet potatoes. For a little etymology on the word "yam," says "African slaves in the South called the sweet potato 'nyami' because it reminded them of the starchy, edible tuber of that name that grew in their homeland. The Senegalese word 'nyami' was eventually shortened to the word 'yam.'"

What's your favorite way to eat a sweet potato? Do you cover it with marshmallows? Any recipes to share?

University of Pittsburgh
Researchers Create Motorized Wheelchair Made for the Water Park

Despite advances in technology, there are many aspects of the world that remain inaccessible to people with disabilities. But researchers at the University of Pittsburgh are working to make one activity easier for people who use motorized wheelchairs: navigating water parks.

The average motorized wheelchair has a number of electrical and battery components that can’t get wet, limiting who can access the joys of splash parks and pools. But a new wheelchair that uses compressed air instead of a heavy battery could change that, Gizmodo recently reported.

Created through a joint research project between University of Pittsburgh engineers, the university’s medical center, and the U.S. Department of Veterans Affairs, the PneuChair is lighter and quicker to charge than traditional motorized chairs. It can also be repaired with basic hardware tools if something breaks in the midst of all the splashing.

The 80-pound chair (a traditional device can weigh up to 400 pounds) can travel about three miles on one charge, about a third of the maximum distance of an electric mobility device. Another benefit: It only takes 10 minutes to recharge rather than eight hours.

The university's Human Engineering Research Laboratories is also working on a scooter version for people who don't need the assistance of a full chair. “The potential to open opportunities for people with disabilities who need powered mobility to access splash parks, water parks, beaches or pools is transformative,” lab director Rory Cooper told the university's press service.

The PneuChair was designed in part for use at Morgan’s Inspiration Island, an upcoming water park in San Antonio that’s designed for people with disabilities. The accessible splash park—which is part of Morgan’s Wonderland, a fully accessible theme park—will initially offer 10 of the chairs to its guests for use while they’re there.

Dietribes: Cabbage

• Cabbages are derived from the wild mustard plant of the Mediterranean region, and have been popular since ancient times. Cato the Elder praised the cabbage for its many medicinal uses.

• Cabbages are highly nutritious, containing large amounts of Vitamin C, folate and fiber. That and its low calorie count is why some people use cabbage on weight-loss diets.

• However, the cabbage is also known to have a certain undesirable gastric side effect. As Nicholas Culpeper said in A Complete Herbal (1653) "Cabbages are extremely windy, whether you take them as meat or as medicine, as windy meat as can be eaten, unless you eat bag-pipes or bellows."

• Remember "freedom fries"? That wasn't the first time the name of one of our foods has been attempted to be changed because of political fervor. During World War I, Americans renamed sauerkraut "liberty cabbage."

• No one knows exactly how the Cabbagetown neighborhood in Atlanta got its name, though stories include the idea that the original poor Scotch-Irish residents (workers at the nearby cotton mill) would grow cabbages in their front yards, and that the smell of cooked cabbage was a nuisance (and later a point of pride). Other apocryphal suggestions include a train derailing or a Model T car overturning and spilling cabbages everywhere for people to snatch up, shouting "Free Cabbages!"

• Georgia has another cabbage connection - Cabbage Patch Kids, which were originally called Little People. In the late 1970s, art student Xavier Roberts started creating "soft sculptures," which he later expanded on by giving them birth certificates and allowing "adoptions." In 1982 the name changed to Cabbage Patch. By the mid-80s, the dolls went on record as having the most successful and in-demand introduction of a toy ever.

• Though cabbages have often been thought of throughout history as a cheap food, that's certainly not true in Northern Canada, where a cabbage can cost $28. The northern Canadian territory of Nunavut is so remote that anything not a product of hunting and gathering must be flown in.

• By the way, that corned beef and cabbage you cook up for St. Patricks Day? Not actually Irish. Though corned beef was made in Ireland in the 17th and 18th centuries, most Irish families were too poor to eat it. Instead it went to British citizens as well as the British and U.S. military. These days, the Irish reportedly find the dish just plain boring.

• Cabbages can have a killer instinct - genetically modified cabbages can produce scorpion poison that kills caterpillars when they bite leaves. But don't worry, the toxin is modified so it isn’t harmful to humans. (I like that the title of the article is "Venomous Cabbage"!)

• Another way to get rid of pests in your cabbage? Er, human urine. According to a 2007 study, "Our results show that human urine could be used as a fertilizer for cabbage and does not pose any significant hygienic threats or leave any distinctive flavor in food products." Good to know?

• The largest cabbage on record was called "The Beast" and weighed 127 pounds. Reportedly it wasn't actually particularly tasty, so it ended up as compost rather than on anyone's plate.

• How do you like to eat your cabbages, Flossers? And have you found a way to counteract their less-desirable side-effects?
