Health briefs: Mean screens for the American child

The average American child spends four to five hours a day in front of a screen - that's roughly one-third of their waking time either in front of a TV or a computer, and all that screen time could be adding up to poor health. Negative health effects are many, and include weight issues, impaired attention, even increased aggression.

Salt talk

Don't be fooled by claims on gourmet salt. They have virtually the same amount of sodium as regular table salt, but a far greater price tag. Regular table salt does have additives that some people believe give it an off taste. Many of the gourmet salts have small amounts of magnesium, calcium and other "natural" minerals that affect the color and perhaps the taste. But the amounts are usually far too small to be of any nutritional significance.
