So you'd like to know how much calcium you actually need in your daily diet? You may have heard of the Recommended Dietary Intake for Australians (RDI's) which are an indication of how much of certain nutrients you need per day. Specifically for calcium, how much you need depends on your age and gender:
Short-term food restrictions tend to be associated more with ileostomies than with colostomies. The foods that cause the most concern are those containing cellulose: the natural fibre, or skeleton, that holds fruits, vegetables, nuts, and grains together.
Salt intake. Most people already have enough salt (sodium) in their normal daily foods, and the bowel soon adapts to make sure that this is absorbed efficiently. So there is no need to add extra (table) salt to your diet if you have an ileostomy, unless you have been advised to do so by your medical team.
