Why so jittery?

The trend of food companies infusing their products with caffeine has become a concern for the U.S. Food and Drug Administration, according to SFGate.com. New products like the Wired Waffle (pictured, 200 milligrams of caffeine), Wired Syrup (84 milligrams per serving), Jelly Belly Extreme Sport Beans (50 milligrams per 1-ounce bag), and caffeine-boosted sunflower seeds from Sumseeds (140 milligrams per 1.75-ounce bag) increase the risk of overconsumption of caffeine, especially for children.

In May, the FDA began a new investigation into how much caffeine is too much and what foods are appropriate for caffeine-infusion. Currently, the FDA considers 400 milligrams of caffeine a safe daily limit for adults.
