There are nearly as many "tricks" to reduce the gas effects of beans as there are cooks. I've never seen any scientific study or empirical evidence that measures the true flatus quotient of beans or other foods. All I have heard or seen are based upon rumor or folklore.
None of the suggestions I've seen, and I've tried most of them, have had any significant influence on my system after eating typical gas producing foods. I would not discourage you from trying any of them. After all, what do you have to lose?
Intestinal gas and flatus caused by indigestible complex sugars in certain foods varies from person to person. What may work for one person may not work for another. My father could eat beans, cabbage, cucumbers, etc. and suffer little gassy consequence, however, I must have inherited my mother's digestive system since I could fill a blimp after enjoying the same foods no matter how they were prepared.
The gas is caused by bacteria in the intestine which is able to digest the complex sugars and the gas is the byproduct of their digestion. The only true method of relieving the gas without lighting up the room is to keep the intestinal bacteria from having a feast by breaking down the complex sugars into digestible sugars. There is an enzyme contained in certain molds that will break these sugars down to more simple compounds. This enzyme is sold over the counter as a supplement pill or liquid under brand names such as Bean-o and Bean-zyme.
Perhaps someone should write to MythBusters to take on the bean challenge.
