Five healthiest nuts ranked by nutrition experts, with walnuts at the top
Nutrition experts crown walnuts, pistachios, almonds, Brazil nuts and cashews as the five healthiest nuts, each offering distinct benefits: walnuts for omega-3 ALA and brain/heart health; pistachios for a balanced mix of protein, potassium and eye antioxidants; almonds for fiber and magnesium supporting blood sugar and heart health; Brazil nuts for selenium (best in moderation); and cashews for magnesium and zinc aiding immunity and energy metabolism. Because nuts are calorie-dense, stick to appropriate portions.
