Nuts would also be beneficial against Alzheimer’s and to improve cognition

American researchers explain in an article published in Journal of Alzheimer’s Disease that a diet rich in nuts reduces the risk of developing symptoms of Alzheimer’s disease. In this study, researchers analyzed the effect of walnut supplementation on a model of transgenic mice that develop Alzheimer’s disease. At 4 months, the mice began to follow a special diet. Some have been supplemented with 6% or 9% nuts, which would correspond in humans to 28 g or 48 g per day respectively. The mice were examined at 13 to 14 months of age for learning abilities, memory, anxiety and locomotor activity.

Results: Alzheimer’s mice that ate a nut-free diet showed memory deficits, anxious behavior, problems with spatial learning and motor coordination. Alzheimer mice supplemented with nuts had better memory and learning abilities, less anxiety and better motor development than Alzheimer mice without nuts. The behavioral performance of Alzheimer’s mice that ate nuts was even comparable to normal mice!

A high, long-term consumption of nuts also improves the cognitive performance of older people. This is what a study published in the Journal of Nutrition, Health and Aging reports, in which researchers assessed the impact on mental health of the consumption of nuts and other oilseeds in 4,822 participants aged 55 and over. followed for more than 20 years.

According to the results, a daily consumption of more than 10 g of nuts (but also peanuts, hazelnuts, almonds, etc.) improves cognitive abilities by up to 60%, particularly thinking, reasoning and memory in the elderly, compared to the group that did not consume nuts. the population mainly consumed peanuts.

The WHO estimates that 47 million people suffer from dementia worldwide. This figure is expected to reach 75 million in 2030. Age is the most important risk factor for cognitive decline. In the absence of effective treatment, dietary interventions that help slow the decline in cognitive performance are simple strategies to implement.
