You might have heard of death by chocolate, but in actuality, while consuming too much sugar has a wide variety of unhealthy side effects, including weight gain, high blood pressure, and diabetes, it’s unlikely to actually kill you directly.Although there are no real-life case studies, scientists at the American Chemical Society calculated the “Lethal Dose 50” for sugar, meaning the amount needed to kill at least half of a test population after consuming a large amount in a single sitting. According to their calculations, a 180-pound human would need to eat around 5.5 pounds of pure sugar in one sitting to have a 50% chance of death from overdose. So you can safely enjoy your sweets in moderation.
