Once dismissed as a simple snack, almonds are now gaining recognition as a powerful superfood. New research suggests they may play a key role in supporting gut health and reducing the risk of dementia, according to nutrition experts.
For years, almonds were seen as little more than animal feed or an occasional treat. Many people avoided them due to their high calorie content, especially during dieting.
However, nutritionists now say this perception was misleading. Almonds are increasingly being recognised for their broader health benefits, particularly for the intestines and brain.
According to experts, almonds are rich in omega-6 fatty acids, monounsaturated fats, fibre, vitamin E, and polyphenols. These nutrients are linked to improved blood vessel health and reduced inflammation.
Better blood vessel function is considered crucial for brain health. Research has shown that healthier blood flow may lower the risk of dementia and other neurological conditions.
Polyphenols found in almonds are bioactive compounds that influence pathways responsible for reducing inflammation. These compounds also support the gut microbiome, which is increasingly being linked to overall brain health.
In addition, almonds contain arginine, an amino acid that helps produce nitric oxide. Nitric oxide allows blood vessels to dilate, keeping them flexible and healthy.
Expert view from King’s College London
Professor Sarah Berry, Chief Scientist and Associate Professor at Zoe, King’s College London, described almonds as a “nutritional powerhouse.”
She explained that almonds support blood vessel function and the gut microbiome, both of which are associated with brain health and dementia risk. According to her, their combination of fibre, healthy fats, and bioactive compounds makes them particularly beneficial.
The research drew on data from more than 160,000 adults in the UK and the US who participated in the Zoe Predict 3 study. The results showed a clear pattern among participants.
People who reported eating almonds daily had significantly lower rates of conditions such as dementia, Parkinson’s disease, stroke, multiple sclerosis, and epilepsy.
Experts note that almonds can be consumed in various forms. They are often eaten plain or combined with butter and milk, making them easy to include in daily diets.
Despite their calorie content, nutritionists emphasise that their health benefits outweigh earlier concerns.
