How many cigarettes could be smoked without doing at least some harm to our health, and could thus constitute smoking in moderation? If we say none, we may, indeed, be right, but now we’ve redefined how we’re willing to work with the concept of moderation. The same logic may also apply to sugar. If it takes twenty years of either smoking cigarettes or consuming sugar for the consequences to appear, how can we know whether we’ve smoked or consumed too much before it’s too late? Isn’t it more reasonable to decide early in life (or early in parenting) that not too much is as little as possible?
