Many humans claim to have a “sweet toothâ€. Yet, excess sugar isbad for our health. Presumably, our craving for sweet foodsubstrates has an evolutionary basis – it probably directed humanancestors to forage for fruit, not candy. What nutritional benefits(name at least three) do we get from fresh fruit? Why is the amountof sugar contained in a few pieces of fruit not bad for us? Giventhat most of the fruit matter (cell wall) is indigestible to us,what is the reason for ingesting cellulose?
