Dietribes: Watermelon

watermelon3.jpg

With spring now here and summer just around the corner, let's talk about a favorite warm-weather food. Ladies and gentlemen, coming in at 92% water, the watermelon! Mark Twain wrote in Puddin'head Wilson that "The true southern watermelon is a boon apart and not to be mentioned with commoner things. It is chief of this world's luxuries, king by the grace of God over all the fruits of the earth. When one has tasted it, he knows what the angels eat." Couldn't have said it better myself. Now let's get to some facts.

"¢ According to the Cambridge History of Food, "Archaeological data suggest [watermelons] were first cultivated in ancient Egypt more than 5,000 years ago, where representations of watermelons appeared on wall paintings and watermelon seeds and leaves were deposited in Egyptian tombs [...] Their first recorded appearance in Great Britain dates to 1597," after which they made their way to the Americas where they have enjoyed a rich cultural history. Today, China is the largest producer of watermelons.

"¢ Examples of watermelon fans in the early United States include Thomas Jefferson, who was an enthusiastic grower of watermelons at his Monticello estate, and Henry David Thoreau. As written in a collection of Thoreau manuscripts that was published in 1999: "I have no respect for those who cannot raise melons or who avoid them as unwholesome." / "When I go a-berrying in my boat or carriage, I frequently carry watermelons for drink. It is the most agreeable and refreshing wine in a convenient cask, and most easily kept cool."

"¢ Watermelons come in many shapes and sizes. In 1954, C. Fredric Andrus developed a breed of watermelon called the Charleston Gray, revolutionary because of its oval (as opposed to round) "“ and therefore stackable "“ shape, as well as its resistance to disease. Even more stackable: the square watermelon...

"¢ The largest watermelon on record belongs to Bill Carson of Arrington, TN, who in 1990 grew one that weighed in at 262 pounds. He may have been outdone for largest watermelon though by this water tower in Luling, Texas.

"¢ The science behind thumping a watermelon. I don't claim to be an expert, but I have been known to pick a good one or two based on a hardy knock. I also love seeing men and women at the grocery store wrestle down melons on the floor, listening intently for just the right note.

"¢ One of my high school teachers used to say, "if it's wet and not yours, don't touch it." But what if it's watermelon snow? This phenomena occurs only in very specific conditions, but causes impacted snow to take on a pink color and, in an even more impressive manner, the smell of a watermelon. Don't get too excited, though. Turns out it's just algae.

"¢ I'm pretty lazy, so I very much enjoy seedless watermelons. If you've ever wondered how they came about, this description should set you straight: "The seedless condition is actually sterility resulting from a cross between two plants of incompatible chromosome complements. The normal chromosome number in most living organisms is referred to as 2n. Seedless watermelons are produced on highly sterile triploid (3n) plants, which result from crossing a normal diploid (2n) plant with a tetraploid (4n)." Mmm, does that make you hungry?

Anyone have any good memories that include watermelon? And does anyone know why artificial watermelon flavor tastes nothing like a real watermelon (but is, I must admit, still delicious)?

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?
