Walnuts are among the healthiest nuts you can eat. They support heart and brain health, help reduce inflammation, and may even improve sleep quality.
Still, they’re calorie-dense and can trigger severe allergic reactions in sensitive individuals. With proper portion control and storage, walnuts can be a daily part of a balanced, heart-healthy diet for adults, children, and pregnant women alike.
A small handful a day — or a modest serving before bed — is often enough to enjoy their many benefits without the downsides.
