A 1-ounce serving of English walnuts, which typically amounts to about 14 walnut halves, provides approximately 185 calories. While walnuts are calorie-dense due to their high fat content, they are rich in healthy polyunsaturated fats, including the beneficial omega-3 alpha-linolenic acid (ALA). This combination of nutrients offers significant health benefits, making them an excellent addition to a balanced diet when consumed in moderation.
