Nutritional concerns are causing more and more people to seek nutritional advice. However, the plethora of advice available from many sources can seem overwhelming and sometimes misdirected. Many concerns are individualized, because we are not all built the same way. Different foods can affect two people in different ways, even if they have the same diagnosis. Therefore, the best thing you can do is listen to your system — it will send messages to you if you let it. This chapter will guide you in dealing with special nutritional concerns. Other tools and support from a doctor, registered dietitian, journaling, and counseling can be extremely helpful as well.
