Walnuts Rank High on New Nutrition Scales Walnuts rank highest among the nuts in Index of Nutritional Quality (INQ). Because INQ relates to nutrient density, we looked at specific nutrients known to be abundant in nuts and peanuts: protein, fiber, omega-3, omega-6, vitamin E, potassium, magnesium, and zinc. Walnuts are a whole food rich in antioxidants, alpha-linolenic acid (ALA), an essential omega-3 fatty acid, protein, fiber, and more. Whole walnuts receive the 'best nutritional value' three star ranking (the highest) due to their nutrient profile. |
