&gt; <i>...your body needs certain kinds of sugars to function...</i><p>I would really like to see the citations that &quot;body needs certain kinds of sugars to function&quot; connotes that we must perforce consume sugar in some form (which I interpret &quot;not the greatest thing in the world for our bodies&quot; implies while we might not have to eat table sugar, we need to at least eat carbs that can be readily converted to glucose), at least in modest amounts. People who start out as epileptic children put on strict ketogenic diets able to carry out successful lifestyles for decades without any other restrictions are <i>prima facie</i> empirical evidence that we most assuredly can synthesize what little sugars our bodies do require beyond very small amounts of daily net carbohydrates (20g per day or less, equivalent to 5 teaspoons table sugar), and do not have to include sugars in our diets.
