Add notes/ingredients to pre-programed food?

Hi everyone! Brand new to this app. I have celiac disease and am trying to use this app to keep track of the foods I eat. I don't care as much about calories, more about nutrition and ingredients. So, my question is that next to a pre-programed food, is there any way to add the ingredients of that food, or view the ingredients for the food? For example, I entered in a coconut lara bar- and while it's great that it has the nutritional content, I was hoping to be able to view the actual ingredients in the bar. Is there a way to view this? And if not, is there a way for me to make a manual notation next to the food with the ingredients?

Thank you!
