Chocolate "High"
Taking the female food/mood research a step further, University of Michigan researchers have linked the desire for sugar with its ability to calm; for fat, with its ability to elevate moods. Adam Drewnowski, Ph.D., director of the Human Nutrition Program at the University of Michigan, believes it's not carbohydrates we crave, it's fat.
The real craving, he thinks, is triggered when we combine sugar with fat, creating a sweet-and-creamy concoction that's hard to resist. According to Drewnowski and Barbara Smith, Ph.D., a researcher at Johns Hopkins University in Baltimore, it is endorphins-naturally occurring substances in the brain that produce pleasurable feelings-that function as pain killers. They believe we crave high fat, sugar-laden foods to experience the blues-bursting benefits of endorphins. These findings could explain cravings for chocolate. With its 50 percent fat/50 percent sugar content-plus an endorphin-releasing substance called phenylethylamine-chocolate may offer the perfect blend of ingredients both to stimulate and soothe at the same time.
The fat and sugar in chocolate can raise both serotonin and endorphin levels, which explains why women may crave chocolate both before and during their menstrual periods. But because it's not nutritionally smart to eat chocolate, to get the same brain-chemical change, choose high complex carbohydrates, such as whole grain bread or crackers to stabilize serotonin levels. To keep endorphin levels up, try a regular exercise program.
But what if the chocolate urge doesn't go away? Debra Waterhouse, MPH, RD writes in her book about chocolate cravings, "there is no evidence that small amounts of chocolate pose any harm to health or well-being (so) satisfying a chocolate urge in moderation might be the best strategy."
