Walnuts are often called “brain food” for a reason. With their high omega-3 fatty acid content, they provide essential fats that support brain structure and function. DHA, a type of omega-3 found in walnuts, is known to improve cognitive performance and reduce inflammation in the brain. In addition to brain health, walnuts benefit the heart. Studies show that daily consumption can reduce LDL cholesterol and improve arterial flexibility, reducing the risk of heart disease. Their antioxidant profile, including polyphenols, also helps protect the body from oxidative stress. Walnuts are also associated with better mood regulation and sleep quality, thanks to compounds like melatonin and magnesium. Incorporating a few walnuts into your daily routine can support both mental clarity and emotional balance. Whether added to smoothies, oatmeal, or simply eaten raw, walnuts are an easy addition to a healthy lifestyle.
