Three Metabolic Drivers Of Mental Illness
- Refined carbs and seed oils drive inflammation, oxidative stress, and insulin resistance, key drivers of many mental illnesses.
- Lowering exposure to these three harms can protect long-term brain metabolism and mental health.
Limit Linoleic Acid–Rich Seed Oils
- Reduce intake of refined seed oils high in linoleic acid because they cross into the brain and are largely burned for energy there.
- Follow the precautionary principle and avoid unnecessary industrial seed oils until clearer data exists.
Linoleic Acid Accumulates In Body Fat
- Americans now store far more linoleic acid in body fat (~21%) compared with hunter-gatherers (~4%), raising concern over cumulative exposure.
- Because body stores are large, stopping intake now prevents further accumulation and potential long-term harm.
