HI M.,
Good advice so far! Diet is very important and most odors are diet related. If your lifestyle will adjust easily, fruits and veggies are terribly important and also limiting sugars which also include bread and potatoes. Avoid processed foods and that includes ALL fast foods.
I would recommend an absorbable chewable multivitamin for her. My family takes a vitamin that is guaranteed to absorb. (Dodge the Flintstones and the generic at the drug stores.They are dangerous.) That will help with getting nutrition into her system and it will also build her immune system to the point that an occasional treat at Mickey Ds will not do as much damage.
Hope this helps!
M.
