Domesticated chickens have been providing humans with eggs for nearly 8,000 years, but having access to freshly laid eggs is no longer restricted to those living in the country.

Caffeine was isolated from the coffee samples and measured by gas chromatography. Every serving but one - instant decaffeinated Folgers Coffee Crystals - contained caffeine, ranging from 8.6 milligrams to 13.9 milligrams. In comparison, an 8-ounce cup of drip-brewed coffee typically contains 85 milligrams of caffeine. In the study's second phase, scientists analyzed 12 samples of Starbucks decaffeinated espresso and brewed decaffeinated coffee taken from a single store.
A 6-ounce cup of regular coffee contains between 75-150 milligrams of caffeine, according to Johns Hopkins researchers. Instant coffee has less, an average of about 70 milligrams, while an espresso contains about 40 milligrams. Six ounces of brewed tea has about 30 to 90 milligrams of caffeine. A 12-ounce cola may have 30 to 60 milligrams. An 8.4-ounce can of Red Bull Energy Drink boasts 80 milligrams.
