Nuts are tiny powerhouses for your heart

Nuts are packed with healthy fats, like monounsaturated and polyunsaturated types, that actively protect your heart. These fats help lower "bad" LDL cholesterol while keeping "good" HDL levels healthy. Walnuts and almonds, for example, also deliver omega-3s, which fight inflammation in your arteries. The American Heart Association notes that adding nuts to your diet can significantly reduce heart disease risk by improving blood vessel function and preventing plaque buildup.
