If you have food allergies or intolerances, it is important to be cautious about consuming certain protein foods. For example, if you have a seafood allergy, you should avoid fish and shellfish. If you have lactose intolerance, you may need to choose lactose-free or low-lactose dairy products or opt for non-dairy protein sources. It is essential to read food labels and consult with a healthcare professional or registered dietitian if you have any food allergies or intolerances.
