Foods to help At the end of your business lunch or romantic dinner, munch the sprig of parsley that's left on your plate. Parsley is rich in chlorophyll, a well known breath deodorizer with germ fighting properties. If you can get hold of an orange, peel and eat it. The citric acid it contains will stimulate your salivary glands and encourage the flow of breath-freshening saliva. If there are no oranges in sight, eat whatever is available, except known breath-pollutants such as garlic, onions or a stinky cheese. Eating encourages the flow of saliva, which helps to remove the unpleasant, odour-causing material on the surface of your tongue.
