I got into an discussion with a girl over whether people need sugar in their diets. This discussion started after one of our friends told us they are allergic to sugar. (They have quit adding any sweeteners to foods)
Her basic argument is that people need sugar, honey, or other sweeteners in order to be healthy. She said that sugar is essential to avoid loosing excessive body weight.
I said that fruits, vegetables, and perhaps other food groups naturally contain sugar. This sugar is all that is necessary for health.
So, is sugar a necessary component of the human diet? Are there any risks in avoiding added sugars?
