Nuts, packed with essential nutrients, have been extensively researched for their potential to enhance brain and cardiovascular health. Diet plays a crucial role in maintaining both brain and heart health, as the intake of certain nutrients can impact cognitive function and blood circulation. A lack of healthy fatty acids, antioxidants, and fibre has been linked to an increased risk of memory decline and cardiovascular diseases.
Therefore, a balanced diet rich in these elements is vital for long-term prevention of these issues. One food that stands out for its nutritional benefits and its ability to boost memory and heart health is nuts, particularly walnuts. Regular consumption of these can lower the risk of heart diseases and improve cognitive performance, making them indispensable for brain and circulatory system health.
A clinical trial published in Clinical Nutrition explored the effects of sustained nut consumption on brain vascular function in older adults. Over a 16-week period, participants added 60 grams daily of cashews, walnuts, hazelnuts, and pistachios to their diet. The result was improved cerebral blood flow and enhanced performance in memory tests.
The study found increased blood flow in key areas of the brain, including the frontal lobe and prefrontal cortex, which are critical for cognitive function. A study featured in The American Journal of Clinical Nutrition has shown that eating nuts, particularly walnuts, at least once a week can lead to a 13% to 19% .
