Why Ultra-Processed Food Is Harmful

Ultra-processed food harms by five mechanisms: excess sugar, low fiber, low omega-3s, emulsifiers, and industrial additives.
These factors collectively link ultra-processed food to metabolic and mental illnesses, including dementia.

Reengineering Processed Food Worked

Lustig worked with a food company to re-engineer products and tested 18 healthier items that sold without hurting profits.
They re-engineered products under principles: Protect the liver, feed the gut, support the brain.

Start With Purpose And Connection

Clarify core values and relationships before tackling addictive consumption; prioritize love and connection over pleasure.
Without stable relationships and purpose, food-based dopamine will persist as primary pleasure.
