1For decades, relief workers had been frustrated in their ability to effectively help victims of famine throughout the world. 2In villages without electricity, it was useless to give people supplies of milk because there was no way to keep the milk from spoiling. 3Powdered milk or grain was equally useless because most villagers didn’t have clean water with which to mix it. 4Then a few years ago, a French nutritionist developed a paste made of peanut butter, vegetable oil, powdered milk, and powdered sugar, and enriched with vitamins and minerals. 5Since the paste didn’t need refrigeration, water, or cooking, mothers, simply squeezed it out of plastic packages to feed their children. 6The results have been miraculous, children who consume the peanut butter paste add pounds rapidly, often going from a near-death state to relative health in a month. 7Not surprisingly, some are calling the paste the greatest health breakthrough since the antibiotic penicillin.
