UCLA students dig into the physics of food – latimes.com

A class at UCLA teaches all about the science behind what makes lettuce crispy, coffee bitter, and apple pie truly tasty.

The three undergrads looked warily at the pulverized apples in their bowl.

The would-be pastry chefs had planned to drop dollops of the mixture into a chemical bath, creating fruity spheres with a filmy skin and an oozing interior. Their early attempts left a lot to be desired. The apple mush was bland, like baby food. The finished globules were teardrop-shaped rather than round. And they were chewy, like aging Jell-O.

“It needs sugar,” Amirari Diego said, with a sigh.

Diego and his two buddies, Stephen Phan and Kevin Yang, were playing with their food for the sake of science — and their transcripts.

They’re students in Physiological Sciences 7 (that would be Science & Food to you and me), a class at UCLA that teaches all about the physics that make lettuce crispy, meat chewy and dough springy; the molecules that make coffee bitter, and carrots sweet.

The 7 Minute Workout (HICT)

The Scientific 7-Minute Workout – NYTimes.com

Exercise science is a fine and intellectually fascinating thing. But sometimes you just want someone to lay out guidelines for how to put the newest fitness research into practice.

An article in the May-June issue of the American College of Sports Medicine’s Health & Fitness Journal does just that. In 12 exercises deploying only body weight, a chair and a wall, it fulfills the latest mandates for high-intensity effort, which essentially combines a long run and a visit to the weight room into about seven minutes of steady discomfort — all of it based on science.

“There’s very good evidence” that high-intensity interval training provides “many of the fitness benefits of prolonged endurance training but in much less time,” says Chris Jordan, the director of exercise physiology at the Human Performance Institute in Orlando, Fla., and co-author of the new article.

Work by scientists at McMaster University in Hamilton, Ontario, and other institutions shows, for instance, that even a few minutes of training at an intensity approaching your maximum capacity produces molecular changes within muscles comparable to those of several hours of running or bike riding.

Interval training, though, requires intervals; the extremely intense activity must be intermingled with brief periods of recovery. In the program outlined by Mr. Jordan and his colleagues, this recovery is provided in part by a 10-second rest between exercises. But even more, he says, it’s accomplished by alternating an exercise that emphasizes the large muscles in the upper body with those in the lower body. During the intermezzo, the unexercised muscles have a moment to, metaphorically, catch their breath, which makes the order of the exercises important.

The exercises should be performed in rapid succession, allowing 30 seconds for each, while, throughout, the intensity hovers at about an 8 on a discomfort scale of 1 to 10, Mr. Jordan says. Those seven minutes should be, in a word, unpleasant. The upside is, after seven minutes, you’re done.

Big Fat Lies

Clip from the documentary “Fat Head.” Guess what? Fat and cholesterol don’t cause heart disease. The theory was based on bogus science from the very beginning.

The Baked Kale Chips Experiment

I’m experimenting with baking my own Kale Chips. Lately I’ve become a fan of them but the commercial variety just seems so expensive so I’m giving this a try.

My research consists of a few ideas and recipes I found online:

The MapMyRun Plugin

This site is going to test out and use Jeff McReynolds’ MapMyRun WordPress plugin which will allow me to connect (link) my post here with my MapMyRun, MapMyRide, MapMyWalk & MapMyHike maps by adding a short-tag to my posts with the route id and the type of activity. i.e. like this for a shakedown bike ride I did the other day:
