The earliest treats came straight from nature such as date palms and other fruit trees, and honeycombs from bee hives. It has only been since the invention of manufactured sugar that the great unwashed have had easy access to sweet and sugary treats.
Sugar seems to be added to nearly every processed food product. This forces consumption of sugar upon the unwary consumer.
Ingredient food labels list sugar content by grams. Since a gram sounds so much smaller than a teaspoon or tablespoon we can easily kid ourselves into thinking it's not that much.
The formula is pretty simple:
4 grams of sugar in a product = one teaspoon of granulated sugar.
