Okay so we all know that we need energy to make our bodies work and that energy comes from macronutrients (ie carbs, fat, protein), but why from ONLY those three things? Isn’t there other forms of store energy in plant and animal matter that we could use to power our bodies? After all aren’t those three macro nutrients just chains of carbon and hydrogen with some other stuff hanging on, surely there most be other compounds that are similar enough that we could use as an energy source ?
In: Biology
There are more than three types of macronutrients – alcohol and ketones are examples of others.
But the reason we focus so much on the big three is because they are the ones most present in the foods we normally eat, so we’ve evolved to specialize in eating them, and as we’ve become more advanced as a species we’ve prioritized growing/raising the things that contain them for food.
