Too much air swallowed can cause farting
I used to be a big farter. Some day I simply had enough and looked for professional advise. Here is the result:
We swallow about 2-3 liters of air every day together with food and beverages. Eating fast, not chewing well and eating and drinking things that contain too much gas or air (coke, sprite, etc., fresh bread, ...) increase the amount of air/gas swallowed.
A part of the gas leaves the body through the mouth (belching), but the bigger part passes through the guts and causes farts.
Shakes are full of air as the process mixes air with liquid !!!
This advise seems ridiculous, but it is not. First it comes from a specialist and second it helped me get my farts under control.
Of course there are other causes for farts like certain food or food combinations. I, for example, can't stand milk with oat products, couliflower, broccoli, field mushroom, onions.
But this is individual.
Today I do my protein drinks just using whey protein, water and a spoon to mix it carefully.
