One of their main nutrients is alpha-linolenic acid, a plant-based omega-3 fat that supports heart and brain health. Walnuts may help lower LDL cholesterol, improve blood vessel function, and reduce inflammation and oxidative stress.
Their protein and fiber can increase fullness, support blood sugar control, and help with weight management. Walnuts also contain magnesium, melatonin, and tryptophan, which may contribute to better sleep.
However, walnuts are high in calories, and eating too many may lead to weight gain or digestive discomfort. They are also a common allergen, so controlled portions and awareness of individual tolerance are important.
