Brian Maxwell, the developer of the Power Bar, died of a heart attack at 51. I don’t eat Power Bars anymore, but they were my first source of emergency food to staunch hypoglycemic stupor. They worked better than nothing, but didn’t seem a perfect solution. As with most nutritional bars they don’t list the sugar content, and it’s therefore difficult to judge how beneficial they are when I find myself feeling under powered. Too high of a sugar content in a simpler form burns too quickly and gives too sudden of a drop in energy for me to function well.
