“In 1800, an average American would have lived and died never having encountered a single manufactured candy, let alone the array of sugar-sweetened yogurts, snacks, sauces, dressings, cereals, and drinks that now line supermarket shelves. Today, that average American ingests more than nineteen teaspoons of added sugar every day. Not only does most of that never come into contact with our taste buds; our sweet receptors are also less effective than those for other tastes. Our tongues can detect bitterness at concentrations as low as a few parts per million, but, for a glass of water to taste sweet, we have to add nearly a teaspoon of sugar.” We eat too much sugar. The artificial stuff hasn’t done the trick. Can science redesign the real thing to fool our tastebuds? The New Yorker: The Race to Redesign Sugar.
