Does anyone else suffer from this when they have a cold?

Both my children and my husband (obviously an hereditary thing) cannot stand the smell of vinegar when they have colds, flu, anything that affects their sense of smell I guess. This means they cannot eat anything containing vinegar. It also puts them off anything malted or with yeast in as that gives off a similiar smell. Makes for a very bland diet indeed. Anyone else have this problem or perhaps some other smell that is vile to them when sick?
