From the Country of Marin's Nutrition Wellness Program, nutritionist Ellen Szakal taught the class how to read product labels to determine the number of teaspoons of sugar in each serving. A chart listing their favorite snacks and a hands--on exercise counting out a disconcertingly large pile of sugar cubes helped them understand just how much unnecessary sugar they were consuming each day.

It's a skill adults could use, too.

Calculating How Much Sugar Is In A Container
Looking at the Nutrition Facts label on the side of the package, find the number of grams of sugar. Then divide that number by 4. For example, ingesting 65 grams of sugar in a 20-ounce drink bottle (considered 1 serving) means swallowing 17 individual teaspoons of sugar.

Juice Peddler smoothie bike
So much youthful energy, it takes extra hands to hold the jar still.

Berkeley-based Juice Peddler sells kits for retrofitting bikes to become human-powered blenders. From the first-generation's endearingly clunky tricycle platform and antique hand-drill to the fifth-generation's sleek, high-density polyethylene design, the company has been at the forefront of DIY bike blender technology.

The kids took turns pedaling their fruit concoctions and proudly shared tastes of their icy treats with other teams. Lined up for judging, the smoothies created a rainbow of delicious fun: Monkey Melons, Fruit-A-Palooza, Pink Panther, Go Mango, Fruit-A-Licious, and Pink-A-Licous Strawberry.

I'm glad I didn't have to judge, as it would have been a tough call to pick just one winner.

Sammy and Brittney confer on the formulation of their team's smoothie.
