Some experts say the whole concept of “healthy snacking” is an oxymoron. The human body, they argue, wasn’t built to accommodate the average American’s habit of cramming in snacks between meals. “Even three meals [a day] might be too much,” says Dr. Valter Longo, director of the University of SouthernCalifornia’s Longevity Institute.
Others agree. Bouts of fasting, or giving your gut extended breaks from food digestion, may fire up all sorts of disease-limiting, life-extending cellular processes, says Luigi Fontana, a professor of nutritional science at Washington University in St. Louis and Italy’s University of Brescia.
