> Except in the world of "anything is possible," mirror life would have no food. All biomolecules are chiral.
Many essential biomolecules, nutrients, and amino acides are achiral (e.g. carbon dioxide, water, ammonium, phosphate, sulfate, glycine, and more). Mirror organisms could easily - at least in the realm of plausibility - function as autotrophs to convert sunlight, CO2, etc. into organic sugars, or extract energy from inorganic materials like hydrogen or iron paired with CO2.
Possible path for organic zero calorie sugars!
L-Glucose already exists, but the problem is that the amount in, e.g. one soda would make your intestines decide to entirely empty themselves. It's been trialed as a colon-cleansing agent for colonoscopy in much smaller doses than say a can of Coke would need, so it's not very useful in a consumer product.
