Walnuts are considered one of the healthiest nuts when eaten in moderation.
They are rich in omega-3 fatty acids (ALA), which support heart health, brain function, and lower bad cholesterol (LDL). Their antioxidants may also reduce inflammation and support long-term brain health.
Walnuts can help with fullness, blood sugar control, and weight management, and may even support better sleep due to natural compounds like magnesium and melatonin.
However, they are high in calories, can cause allergies, and may lead to digestive discomfort if overeaten.
