Scientists have found that egg proteins, specifically those found in the white, help us stay awake and feel alert. They are much more effective than carbohydrates found in the chocolates, biscuits and sweets often relied on for a quick energy boost. Cambridge University researchers looked at how nutrients affect the brain cells that keeping us awake and burning calories. A mixture similar to the protein content of egg whites activated these cells, triggering the release of the stimulant orexin. Sugar, however, blocked the release of orexin. |
