The effect of diet on depression in older people
Claire Williamson, Nutrition Scientist at the British Nutrition Foundation in London, has reviewed the evidence.
Here are the highlights
- In observational studies, poor micronutrient status (particularly folate and vitamin B12) is associated with an increased risk of depression in older people.
- In observational studies the participants are followed and outcomes are measured, but there’s no attempt to influence the outcomes.
- Supplementation with folic acid enhances anti-depressant drug treatment and there’s some evidence that supplementation with certain micronutrients may help improve depressive symptoms in older patients.
- There’s interest in the effects of omega-3 fatty acids in depression. However, the evidence limited and difficult to evaluate due to considerable variability between studies
The bottom line?
The author concludes, “Research highlights the importance of a healthy diet and lifestyle to help maintain good mental health into old age and health professionals should try to support older people in trying to achieve this.â€
