A new review from the UK confirms a positive impact of a micronutrient-rich diet on cognitive function, and an inconsistent effect on mild cognitive impairment.
In the systematic review, the results of 11 observational studies and one randomized controlled trial, investigating the potential relationship between Mediterranean diet and cognitive functions, were analyzed (1). The study results showed that a greater adherence to a Mediterranean diet was associated with better cognitive function, lower rates of cognitive decline and reduced risk of Alzheimer’s disease. Results for mild cognitive impairment were inconsistent.
The researchers commented that Mediterranean food, which typically consists of higher levels of olive oil, vegetables, fruit and fish, may help to protect the aging brain by reducing the risk of dementia – a link that is not new. Further research is needed to clarify a potential association with mild cognitive impairment. While observational studies provide suggestive evidence, randomized controlled trials are needed to confirm whether or not adherence to a Mediterranean diet protects against dementia, the scientists said.

Embryonic and fetal development, as well as the early life of a newborn, are periods of physiological plasticity during which environmental influences may produce long-term effects. Both undernutrition and overnutrition during these periods have been shown to change disease risk in adulthood. These effects are influenced by the type, timing and duration of inappropriate nutrition.

Evolution has equipped us with a triage mechanism (from the French verb ‘trier’ meaning to sort out): When there is a deficiency of micronutrients in our bodies, they are reserved for short-term survival and reproduction at the expense of disabling DNA repair, which increases the risk of developing chronic disease in the long-term.
