Simply put, ultra-processed foods aren't nourishing your body -- they're destroying it.
You sure you want to eat that?
To break it down (and scare you away from the ice cream tub) even further, ultra-processed foods are lacking three major nutritional properties that us humans need to survive. Most problematically, they're void of soluble and insoluble fiber, because fiber can't be frozen.
Dietary fiber forms lattice work on the upper intestine to inhibit absorption of nutrients, so your body feeds off its own good bacteria; thus, balancing out bad bacteria, improving your metabolic health, and reducing liver fat accumulation.
Lab-created foods also lack micronutrients like antioxidants and vitamins, along with omega-3 fatty acids. Omega-3s stabilize those fragile neuronal membranes that prevent you from developing dementia and early onset Alzheimer's, and are found in flax and wild salmon -- no, frozen salmon dinners don't count! Those farm-raised fishies fed on corn instead of the natural algae that makes omega-3s, so they don't contain the same levels of the essential fat. "You might as well eat a steak," Dr. Lustig says.
