The Telegraph published an article this weekend headlined, “Sugary Snacks Help School Children Concentrate.”

Really?

Here’s what actually happened: In a study of 16 kids, researchers gave them fruit juice containing either artificial sweetener or glucose—the natural sugar that acts as the body’s main energy source. The kids who drank the juice with glucose scored better on memory tests than the ones who ate artificial sugar, and appeared to have longer attention spans as well. Study leader David Benton’s main conclusion, then, was that children might perform better in school if they ate occasional snacks, rather than one big meal, and that a snack with some sugar might not be such a bad thing for them.

A baseball can’t curve without its laces, a tennis ball’s fuzz helps it travel further, and the dimples on a golf ball reduce drag, just like the ridges on a shark. These tidbits of trivia introduced a capacity crowd packed into the purple bleachers of New York University’s Cole Sports Center to the World Science Festival’s “Science of Sports” event Saturday afternoon. Former U.S. Olympic Committee director of coaching Tom Crawford led the event.

The presenters opened with nutrition science, especially important for the young athletes and their families who packed the gym. Three professional basketball players, Leilani Mitchell and Lisa Willis from the WNBA’s New York Liberty and Brevin Knight of the NBA’s Los Angeles Clippers, helped about 10 elementary school-aged participants pick healthy food from a table. (Here’s a tip: After a workout, drink chocolate milk. Besides refueling you with proteins and carbohydrates, it’s delicious.)

We’ve discussed how a mother’s diet may influence her baby’s sex. Now there’s research indicating that a baby’s diet may influence his or her future mental health and intelligence. Researchers for the Early Nutrition Programming Project (EARNEST) have found evidence that an infant’s diet can permanently affect the child’s future cognitive development, mental performance, and even susceptibility to mental illness.

We’ve all been subjected to the health admonition of drinking eight, eight-ounce glasses of water per day—known as 8×8. Humans, apparently, have evolved a chronic water deficit, and must constantly replenish their dessicated bodies with high volumes of fluid until their urine runs clear. Water is supposed to be good for your skin, your weight, your purity, and your brain—which is, afterall, 74% water.

Balderdash, says a new review of the scientific literature by kidney gurus Dan Negoianu and Stanley Goldfarb from the University of Pennsylvania. They found that for the average, healthy individual, there is no evidence that increased water intake benefits organ functioning, appetite, headaches, skin tone, or substance clearance from the kidneys—and the origin of 8×8 is a mystery. The human body didn’t evolve a chronic thirst—it evolved a great capacity for maintaining proper water balance in the face of variable intake.
