Yes, preparation ideas can use optional ingredients that suit your dietary needs and the product directions. Keep the full powder serving, then account for what the additions contribute.
For example, milk or a plant drink may add protein and calories; nut butter adds fat and calories; fruit adds carbohydrate and other nutrients. The amounts vary by ingredient and portion. Water adds no calories, so it can change thickness without changing the powderâs nutrient total.
Check allergens in every added ingredient. Adding soy milk introduces soy; nut butter can introduce nuts. Do not assume a recipe is suitable just because the original powder is suitable for you.
