Why do some people fart a lot, regardless of diet?

I don't very often but when eat peanuts...Oh Lord! Those are bad.
and I think I've said too much
 
In How Food Works, there's a good discussion of the digestive process. One thing that is obvious in the article is that digestion involves "breaking things down." Everything in food has to be broken down into small units in order to enter the bloodstream. Protein must be broken into its individual amino acids, fats must be broken into fatty acids, and carbohydrates (both simple and complex) must be broken into individual glucose (or equivalent) molecules.

Flatulence occurs when a food does not break down completely in the stomach and small intestine. As a result, the food makes it into the large intestine in an undigested state. For example, if you are "lactose intolerant," it means that you lack an enzyme (lactase) in your intestine -- the enzyme that breaks lactose apart into two sugar molecules so they can enter the bloodstream. Without lactase, lactose passes undigested through the stomach and small intestine and arrives in the large intestine.

There, the lactose meets up with billions of hungry bacteria -- the natural "intestinal fauna" we all have in our large intestine. These bacteria are happy to digest lactose. They produce a variety of gases, in much the way that yeast produces carbon dioxide to leaven bread (see How Bread Works for details on yeast). Gases such as methane, hydrogen and hydrogen sulfide are common gases that these bacteria produce. Hydrogen sulfide is the source of the odor we associate with flatulence.

Certain foods produce more flatulence than others because they contain more indigestible carbohydrates than others. Beans, as you might expect, are particularly well-endowed in this regard

because your body isnt producing the right enzimes to lizase (please correct if misspelt, i really need to know this word) the food and there for its getting down to the gut bacteria rather than being absorbed by the body.

This is what happens to people who are lactose intolerant for example, they dont produce lactonaize and there for they cant lizase lactose

Lyse is the word I think you're looking for, though that's rather specific.

Lysase would be an enzyme that causes lysis.

i dont think so, the word im looking for was dirived from either the greek or latin word meaning "to split"
 
YES, thats the word im looking for:)
thanks:)

hydrolysise, to split using water (i compleatly forgot about the water bit)
 
This is simple too, kind of like the breast answer. The reason some people fart all the time is because they are funny people. And farting is innately funny! :)
 
They eat too fast.
They have allergies they are not aware of.
They mix foods they should not mix. (try bananas after refried beans)
Their stomachs do not produce enough acid.
Their intestinal flora was damaged by too much antibiotics.
They eat beans but lack the right enzymes to break it down.
Because they are nervous and it affects their digestion.
Because they have diseases.
Too little saliva.
They swallow air when the eat.
They eat sulfur containing foods.
They actually don't fart more, but they squeeze so you hear it.
 
"They swallow air when the eat"

no this comes up the other end, thats what a burp is
your right about stress effecting digestion though, sympathetic arousal diverts blood flow away from the gut which means that the netruients arnt absorbed and there for get to the bacteria. I dont think your right about the stomic acid though, the only thing this effects is pepsin which hydrolysise's protinee.

I disagree. That air can come out of both ends.

From an online medical resource
Flatulence (Gas) Causes

Excess gas in the digestive tract (which is your esophagus, stomach, small intestine, and colon/large intestine) can come from 2 sources: increased intake of gas, for example, from air you swallow; or increased production of gas as certain undigested foods are broken down by harmless bacteria normally found in your colon.

* Swallowed air (aerophagia): This can occur with improper swallowing while eating or even unconscious swallowing of air out of habit.

* Activities that cause you to swallow air include rapid drinking, chewing gum, use of tobacco products, sucking on hard candy, drinking carbonated beverages, loose dentures, and hyperventilation in anxious people.

* Most people burp or belch to expel this excess swallowed air. The remaining gas moves into your small intestine. Air can be absorbed, but some moves along to the large intestine for release through the rectum.

* Analysis of the gas can help determine if it originated from aerophagia (mostly nitrogen, also oxygen and carbon dioxide) or GI production (mainly carbon monoxide, hydrogen, and methane).

* Breakdown of undigested foods: Your body does not digest and absorb some carbohydrates (for example, the sugar, starches, and fiber found in many foods) in the small intestine because of a shortage or absence of certain enzymes there. So this undigested food then passes from the small intestine into the large intestine, where normal, harmless bacteria break down the food, producing hydrogen, carbon dioxide, and, in about a third of all people, methane. Eventually these gases exit through the rectum.

* Foods that produce gas in one person may not cause gas in another. Some common bacteria in the large intestine can destroy the hydrogen that other bacteria produce. The balance of the 2 types of bacteria may explain why some people have more gas than others.

* Most foods that contain carbohydrates can cause gas. By contrast, fats and proteins cause little gas. These common foods and their natural components may create gas:

* Beans: Beans contain large amounts of the complex sugar known as raffinose. Smaller amounts are found in cabbage, Brussels sprouts, broccoli, asparagus, and in other vegetables and whole grains.

* Starches: Most starches (potatoes, corn, noodles, and wheat) produce gas as they are broken down in the large intestine. Rice is the only starch that does not cause gas.

* Onions: The sugar known as fructose occurs naturally in onions, artichokes, pears, and wheat. It is also used as a sweetener in some soft drinks and fruit drinks.

* Dark beer and red wine

* Sorbitol: This sugar is found naturally in fruits including apples, pears, peaches, and prunes. It's also used as an artificial sweetener in sugar-free gum, candy, and other diet products.

* Fiber: Many foods contain soluble and insoluble fiber. Soluble fiber dissolves easily in water and takes on a soft, gel-like texture in the intestines. Found in oat bran, beans, peas, and most fruits, soluble fiber is not broken down until it reaches the large intestine, where digestion causes gas. Insoluble fiber, on the other hand, passes essentially unchanged through the intestines and produces little gas. Wheat bran and some vegetables contain this kind of fiber.

* Lactase deficiency: Another major source of flatulence is lactase deficiency, which results in a decreased ability to digest lactose, a natural sugar found in milk and other dairy products such as cheese and ice cream and in certain processed food such as bread, cereal, and salad dressing. This flatulence is often associated with diarrhea and cramping but can appear as only gas. Many people, particularly those of African, Native American, or Asian background, normally have low levels of the enzyme lactase needed to digest lactose after childhood. Also, as people age, their enzyme levels decrease. As a result, over time people may experience increasing amounts of gas after eating food containing lactose.

* Other problems: Certain conditions can result in other foods being poorly absorbed in the GI tract, allowing for increased bacterial activity.

* Malabsorption syndromes can be the result of decreased production of enzymes by the pancreas or problems with the gallbladder or lining of the intestines.

* If transit through the colon is slowed down for any reason, bacteria have increased opportunity to ferment remaining material. Therefore, if you are constipated or have decreased bowel function for any reason, flatulence can follow.

* Alterations in bowel habits can be a result of the following:

o Poor dietary fiber
o Parasites
o Inflammatory bowel disease
o Intestinal obstruction (including cancer)
o Diverticulosis or diverticulitis
o Poor thyroid function
o Narcotic and other drug use

Anything that leads to poor digestion means there is greater liklihood that fermentation will take place by the time the leftovers from digestion reach the large intestine. IOW more gas gets created down the line, but not in the stomach.
 
Broccoli has a component known as raffinose that leads to stimulating the fart factor and abdominal bloating. The cruciferous family (includes broccoli, cabbage, kale, and Brussels sprouts) contain a complex sugar called raffinose. The raffinose is not digested by the body. Instead of feeding you, the raffinose ends up feeding the stomach bacteria. Then stomach bacteria express their gratitude by bloating someone.
Men's health magazine recommends not eating broccoli before swimming.



Broccoli sprouts are a world's healthiest food and are able to be quickly grown for spouts that mature in three weeks or less. The baby sprouts have only a smidgen of the raffinose probably compared to the adult plant.

Mixing cheeses with cruciferous may be the best recipe for disaster of a nuclear explosion.

Was recently proven that girls fart more than boys. This has got have something to with all the domestic gassy, aerated products they are consuming as snacks rather than fruits. Dairy, mayonnaise, eggs that are aimed at the females more. Milk and yogurt have more gas filled sort of carbs. Although apples and pears have been proven as the gassiest fruits out there.

Eggs and oranges are two foods known to ancients to be hardest to digest.
Indigestion leads also to mass fart buildup. Eat a fresh orange and reduce OJ drinking that has been thickened with added calcium and/ or stick with a few oranges fresh squeezed.

Cheese warmed and mixed with meat has extra promotion of gas for some reason. So might want to eat them separate. No doubt green beans and kidney or thicker canonelli or navy beans give the worst gas. Black eyed peas that are kin to lentils have less gas. Lentils have lowest gas besides adzuki that have none.

Ice cream has all been extra super duper aerated. Less gas from normal homemade ice cream. So what goes up must come down.

Twice baked products also breakdown quicker. Most companies add excess salt to foods for a quick turnover time if you know what I mean. They want everyone to sh*t the product out and eat more. Excess salt probably assist bloating also.

Hardly anybody nibbles some fennel fresh seed with the meal like so many ancient cultures recommended doing to prevent gas from building up until someone pops.


Carbohydrates that have been over cooked and thereby contain 'acrylamide' such as potatoes chips probably leads to foul smelling gas.
 
Asian girls are extremely healthy and unlike American girls, they do the farting (if any at all) in restroom.
