Study Notes
The Impact of Diet, Gut Bacteria, and Exercise on Mental Health
- Following a Mediterranean diet lowers the risk of depression, as indicated by a four-year study of 10,000 university students in Spain.
- Higher intake of fruits and vegetables predicts increased happiness and well-being, equivalent to the psychological gains of employment, as evidenced by a study of 12,385 adults in Australia.
- Nutrients in food provide the foundation for the synthesis of neurotransmitters, such as serotonin, directly affecting mood.
- Gut bacteria have been found to affect psychological function, with specific bacteria associated with higher quality of life indicators and deficits linked to depression.
- Transplanting gut bacteria from children with autism spectrum disorder into mice led to the mice exhibiting autism-like behaviors.
- Ingesting a prebiotic daily for 3 weeks led to participants focusing more on positive information and less on negative, similar to the effects of antidepressant or anti-anxiety medications.
- Consuming two cups of yogurt daily led women to respond more calmly to images of faces displaying negative affect.
- Physical exercise has been shown to be the most effective instant happiness booster, with a positive relationship between exercise and happiness, regardless of the type of exercise.
- Physical activity weakens the association between stress and affect, and exercisers experience fewer days of poor mental health.
- Regular exercise in later life predicts better cognitive functioning and reduced risk of neurocognitive disorders and Alzheimer’s disease.
- Exercise reduces and helps prevent depression and anxiety, with it diminishing depression as effectively as antidepressants and being particularly effective for preventing depression in sub-clinical populations.
- A meta-analysis found that exercise has a large protective effect against the development of depression across age groups and geographical regions, and it similarly reduces symptoms of depression and anxiety in non-clinical adult populations.
