The Claim
Higher intake of unhealthy plant-based foods is associated with a 46% increased risk of cognitive decline in middle-aged and older adults over a 16-year period, with no significant association observed between unhealthy plant-based food intake and risk of mental illness.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
People who eat more unhealthy plant-based foods over 16 years have a 46% higher risk of cognitive decline, but their risk of mental illness is not significantly different from those who eat fewer unhealthy plant-based foods.
See the scientific wording
Higher intake of unhealthy plant-based foods is associated with a 46% increased risk of cognitive decline in middle-aged and older adults over 16 years, but shows no significant association with mental illness risk.
Eating too many sugary and refined plant foods causes blood sugar to stay high for long periods, which damages blood vessels in the brain and triggers inflammation. This inflammation harms the connections between brain cells and kills off neurons over time, leading to memory and thinking problems.
What the research says
1 studyStudy: Quality of plant-based diets and healthy aging: A community-based prospective cohort study.
People who ate lots of sugary drinks and white bread over 16 years were much more likely to have trouble remembering things as they got older, but their risk of depression or anxiety didn’t go up. So, unhealthy plant foods hurt your brain but not your mood.
