Given such a mixed list, we think it makes sense to broaden any recommendation to include most nuts and seeds, including the 4 nuts and 4 seeds belonging to our WHFoods Nuts, Seeds & Oils food group: almonds, cashews, peanuts, walnuts, flaxseeds, pumpkin seeds, sesame seeds, and sunflower seeds. Any combination of these nuts and seeds adding up to 3 tablespoons per day (1.5 ounces, or 42 grams) is a step we recommend for obtaining the special health benefits provided by nuts and seeds.
