Do you have any food allergies or intolerances, and, if so, what are they? The greater the number of foods restricted or eliminated in the diet, the greater the likelihood of nutritional defi ciencies. This question may also shed light on the client’s need for nutrition counseling. For instance, clients with hiatal hernia who are intolerant of citrus fruits and juices may benefi t from counseling on how to ensure an adequate intake of vitamin C. What types of vitamin, mineral, herbal, or other supplements do you use and why? A multivitamin, multimineral supplement that provides 100% or less of the daily value offers some protection against less than optimal food choices.
