WHY DO WE PASS GAS ??....

Everyone has gas. Burping and “passing gas” is normal. All experience bouts of gas, sometime or the other. The collected foods give off gases that can cause bloating. Gas is a natural byproduct of the body. Generally the gas in the body is 
odorless. Gas may  cause bloating and pain.
The odor of passed gas if any is due to sulfur made 
by bacteria in the large intestine.
Everyone has gas in the digestive tract. 
Try to chew the food, avoid gulping and eating
fast which will result in swallowing more air.
People who swallow a lot of air, fart more 
than people who don't. This can be cured  
by chewing with your mouth closed, eating 
more slowly, and not gulping food or liquids.  
Try to avoid foods, flatulence-producing foods
that are  high in certain polysaccharides.
Those foods include beans, lentils, dairy products, 
onions, garlic, scallions, leeks, turnips,radishes, 
sweet potatoes, potatoes, cashews,  artichokes, oats,
wheat, and yeast in breads. Cauliflower, broccoli,
cabbage, sprouts .
Try to avoid anxiety as it involves taking in more air.
A few changes in diet and chewing food properly 
helps a lot.
There are ways to minimize the occurrence of 
gas that occurs normally. Some foods cause
gas more than do other foods. Knowing which
foods may cause more of a gaseous reaction will
help you adjust your diet to decrease the amount 
of gas you produce. Changing your diet, to eliminate
gas-causing foods is one way to reduce formation of less gas.
