Nuts, due to their essential nutrients, have been extensively researched for their potential to enhance brain and cardiovascular health. Diet plays a crucial role in maintaining brain health and the cardiovascular system, 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, adopting a balanced diet rich in these components is vital for long-term prevention of these issues.
One food that has gained recognition for its nutritional benefits is nuts, particularly walnuts. Regular consumption of these can reduce the risk of heart diseases and boost cognitive performance, making them indispensable for brain health and the circulatory system.
A clinical trial published in Clinical Nutrition examined the effects of prolonged nut consumption on cerebral vascular function in older adults. Over a 16-week period, participants included 60 grams daily of cashews, walnuts, hazelnuts, and pistachios in their diet.
This resulted in improved cerebral blood flow and enhanced performance in memory tests. The results showed an increase in flow in key areas of the brain, including the frontal lobe and prefrontal cortex, which are critical for cognitive function.
Another research published 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% decrease in the risk of cardiovascular diseases. Moreover, the risk of coronary disease fell by between 15% and 23%, further highlighting the heart-protective benefits of these foods.
The positive impacts of nuts are attributed to their high levels of healthy fatty acids, fibre, and antioxidants, which help reduce inflammation and enhance endothelial function. These properties not only promote better blood circulation but also have a direct effect on maintaining cognitive abilities over time.
