Gas that smells usually indicates that your digestion is off. Too much sugars can easily mess it up. Eating yogurt and taking a probiotic supplement will help to re-balance the friendly bacteria in the gastro tract.

Also, chlorophyll that is in green leafy vegatables is a great deodorizer for the intestines. You may not get him to eat alot of veggies whereas You may be able to get him to take a Chlorophyll capsule that you can buy at a health food store and Activated Charcoal tablets sometimes work to absorb gas.

As you know it's difficult to change people that think everything is OK.

God Bless You for your Efforts!!
