Your body is not designed to handle the chemical load and altered textures of ultra-processed foods. They disrupt hunger signals, damage the gut lining, inflame the brain, and overload detoxification pathways. They’re engineered to be eaten quickly and in excess, flooding your

What is a UPF? Ultra-processed foods include sodas and energy drinks, packaged snacks, fast food, ready meals, sugary cereals, protein bars, and countless items labeled as “healthy.” If it’s made in a factory, filled with additives, colorings, stabilizers, or flavors, it falls
