How Eating Too Fast Causes Bloating and Gas

Eating proteinThere are several reasons why eating too fast is a major causes of gas, bloating, stomach pain and other intestinal problems.

The most obvious one is poor digestion, but fast eating can cause many other digestive problems as well.

Here’s why eating too quickly makes you fart and 5 benefits of slowing down and enjoying your meals.

The Importance of Chewing Food Properly

Digestion starts in the mouth, not in the stomach. Chewing breaks up the food into more manageable pieces, increases its surface area and mixes it with saliva.

This saliva contains the enzymes amylase, which starts breaking down carbohydrates in the meal and lingual lipase to begin the proper digestion of fats. The whole digestive process can impaired when we are eating too fast.

Along with the enzymes in saliva, there are also antibacterial agents such as immunoglobulin A, lactoferrin, lysozyme and peroxidase and a substance called epidermal growth factor (EGF), which can help heal inflamed intestinal tissues.

If you’ve been eating too fast and scoffing down your food with very little chewing, you increase the risk of inflammation within your gastrointestinal tract.

People often label the associated discomfort ‘stomach pain’ or ‘cramps’, but an inflamed small or large intestine is the more likely culprit.

Slowing down your eating and chewing well produces more saliva with more epidermal growth factor to give any inflammation of the GI tract a chance to heal.

If you suffer from intestinal cramps or stomach pain then one of the best natural cures is to stop eating so fast, slow down and chew your food really well.

Eating Too Fast Feeds Intestinal Bacteria

While some food components, such as certain carbohydrates in beans, are unlikely to be digested, regardless of how well we chew them up. Others, like proteins that can be digested more fully with slower eating, often aren’t when we eat too quickly.

Having too much protein in too large a meal is a common cause of digestive problems and excessive flatulence.

Undigested protein can putrefy in the heat of the large intestine and, with bacterial action, lead to the production of gases like hydrogen sulphide, indoles, skatoles and mercaptans. It only takes a small amount of these gases to create some really bad smelling flatulence.

Digestive enzymes can help with protein digestion, but ideally consider having smaller portions of meat in your meals.Slow food for better digesting

Good quality protein is very important for overall wellness and wellbeing. But large servings of protein based foods, particularly from poor sources like overcooked or processed meats, are unlikely to be digested well.

It’s worse than just wasting all that excess protein when you have a massive steak or huge burger. Too much protein puts a real strain on your whole digestive system and can lead to numerous problems.

It’s also a major cause of those really smelly farts. So go easy on the meat. Quality over quantity makes for better digestive health and less issues with bloating and gas.

Distracted Eating Versus Slow Food

With so many aspects of our lives seeming so rushed, eating a meal really should be a chance to slow down, relax and enjoy our food. This doesn’t seem to be the case for many people.

We eat distracted in front of the TV, or hurrying down lunch staring at the computer screen at work, even walking down the street, sandwich in one hand, phone in the other. Are we even tasting our food anymore or just shoveling it in out of habit?

If you want to avoid indigestion, stomach gas, bloating and flatulence, and possibly larger problems in the future, it’s worth remembering to slow down when eating, taste and enjoy your food and start chewing each mouthful more thoroughly.

5 Beneficial Effects of Eating Slowly

1. Less Swallowed Air

When you rush down food you’re much more likely to swallow air, which can cause stomach gas and abdominal bloating. Eating slowly and chewing food properly means less air is going into the stomach.

This is especially important in the evening, as when you lie down to sleep it’s harder for the stomach gas to escape with burping and it’s more likely to get sent in the other direction and end up as bloating and flatulence.

2. Heal Your Digestive System

Savoring your meals and chewing for longer mixes more saliva with the food you are eating. Salivary fluids are very important for digestion as they start the enzymatic breakdown of your meal.

Saliva also contains antibacterial agents and epidermal growth factor (EGF) that assists in the healing of any inflammation in the intestinal tissues.

When you stop eating so fast and start chewing your food properly, you give your digestive system a chance to heal and prevent future problems.

3. Better Food Choices

When they are fully present when eating and really taste the food in their mouths, many people find that the junk food they used to be addicted to doesn’t really taste that good anymore.

Fast food companies spend millions on researching how to make their products smell better and create flavors that hit your taste buds quickly, but then tend to fade away quite quickly as well.

When you slow down and really examine the taste of that fried chicken and French fries, it turns out to be all oil and salt.

The same is true for those fatty burgers that are really pretty bland when you slow down and taste them properly after the initial hit of engineered flavor.


By setting aside a little more time to eat slower, there is no more need to rush out for junk and many people find themselves making healthier choices for meals.

Not just because they feel better for it, but also for the better depth and complexity of tastes and flavors in higher quality natural food.

Slowing down, chewing food well and taking the time to enjoy eating and concentrating on the texture and flavors of your meals, leads to better digestion and much less stomach gas and bloating.

4. Eat Slower Means Less Calories for Natural Weight Loss

Taking your time and chewing food properly also helps to promote satiety, that feeling of satisfied fullness that signals that it’s time to stop eating.

When you rush your meals the satiety signal is less likely to get triggered. As a consequence you eat more before you feel full.

Simply slowing down when you’re eating and chewing your meals more will help with losing weight. This study found eating slowly helped to maximize satiation and reduce the number of calories eaten by healthy women.

Using a small spoon or fork, taking smaller bites and dividing your meal into multiple portions, with a delay between each, can also help prevent eating too fast.

5. Prevents Gas, Bloating, Body Odor and Bad Breath

When you eat slowly and chew your food properly it can help you to smell better in several ways. Proper digestion affects not just issues with flatulence and belly bloat, but also problems with bad breath and poor body odor in general.

The smaller and better you can chew up your meal, the easier you make proper breakdown of food for your stomach. Which in turn, makes it easier for your small intestine to absorb and leaves less of it undigested for the bacteria in your large intestine to feed on.

It’s these bad bacteria that are a major cause of flatulence and also contribute to offensive body odor as well, through the waste products they emit.

Some authorities recommend chewing each bite at least twenty times before swallowing it to improve digestion and maximize nutritional intake. While this may help at the start, a better way would be to simply eat slower and focus on savoring and enjoy the process of eating.

Take A Little Extra Time Eating

Taking your time eating and chewing your food well, particularly in meals with protein, starts the digestion process off properly and increases the likelihood of the food being absorbed in the small intestine.

Eating too fast and not chewing food properly on the other hand often causes digestive problems. By hurrying a meal down you risk a good portion of it ending up undigested in the large intestine.

The more undigested food that you send to your colon, the more the billions of bacteria down there will happily turn it into bad gas and bloat up your belly.

When you have smaller meals and take your time, rather than eating too fast, you are much less likely to be feeding them so well. Additionally, poorly digested food is a major cause of constipation.

Eating more slowly also helps reduce stomach gas and bloating from swallowed air and gives a feeling of fullness and satisfaction after a meal that eating quickly rarely does. In this way, slowing down and not eating so fast is one of the easiest ways to start losing weight naturally.

Life can be pretty busy sometimes, but eating is one of those important daily activities that is really worth slowing down for and taking the time to taste and enjoy. Your body will thank you for it later.

Nice article. It informed thoroughly on the importence of chewing. Thank you and all the best.


Hi, I love your article and the ideas you shared in this article. I will use it for my grandson. Hope everyone is becoming healthier.


I agree with many of the other readers about this blog, very easy to understand yet highly informative and overall an extremely well written piece. I have got severe intestinal issues after I eat more times than not, I avoid eating out as it can take as little as 5 – 10 minutes for the intense pain and diarrhoea eruption to begin, many times so painful that I also start to vomit. Not fun in a public restroom, or at your in laws house or even worse at work. Doctor was just clueless and not helpful with suggesting any possible explanations and didn’t even lean towards nutritional advice. This was over 11 years ago that it all began (before during and after being admitted to hospital for an open cholestecyomy which was misdiagnosed as a stomach ulcer but was in fact a bile duct obstruction) I resigned myself to the fact that I just have to deal with it forever. After reading and the lactose and fructose articles as well I am seriously thinking that I have found something that will finally help me. I am guilty of rushing my food, drinking while eating, not eating frequently enough so chomping down on huge meals to compensate, no wonder my body hates me, I’m the worst owner it could have gotten. I really needed to see this, it shines a whole new light on things and gives me a logical and safe place to begin to get control of my digestive health and my overall enjoyment of life

    Thank you for your positive comments.

    All the best,



I used to eat fast and also used to speak when eating. After I read your post I tried to eat with my mouth closed and chewed well. I have been trying this for the past 1 week now and I should say I really feel light now. I have one question. For the past 1 week I have been having loose bowels. Is this a good sign of having the accumulated fat drained out or is this something not related to the new eating habit. I also started drinking hot water before going to bed.


    Hi Jeff,

    I’m glad you’re noticing benefits from eating properly. It’s possible that this is already having a mild detoxifying effect, hence the bowel movements. However, it could quite likely be something else. The hot water may also be a factor, though if so I’d expect it to get back into balance soon.

    Hope this helps,



No wonder everytime I eat fast I feel like farting.
I ate fast 4 hours before I had to go to work. And guess what? I had a performance interview that day.

Never eating fast gain ahahahaha. Need to enjoy my food.
Great writeup!


This article is life saver,thanks.


hello boss

I have bloating and gas problem which is not going. please what can I do about it.

and at the sometime have piles too which is really me, so I can go out to work anymore please help me my problem is the exess gas and bloating with the piles too….

Thank you.


Wolfing down food can feel so good though. But for my girlfriends sake, I should probably slow it down.


Food for thought…Thanks for the advice.


I love the scientific reasoning behind the effects on the body. I’m really hoping this will sink in with my scientific 17 year old son. We have all told him he eats way too fast and drinks too much water at meal times and this came to a head last night with spending 7 hours in a&e with him in dreadful stomach/chest pain. ( Everything nasty ruled out.) Your article is just what I need to back myself up. Will let you know if it works. Thank you very much.


    Thanks for your positive comments Janette.

    I hope the article helps as eating too fast and causing an intestinal blockage may well be the cause.

    All the best,



    We had been out shopping for Christmas, took many hours. Didn’t get lunch until 4pm, still rushing. Wolfed down 2 Arby’s and fries. About 20 or 30 minutes later I got terrible sharp pain. (We were supposed to be getting dressed for the company Christmas party, and heading out the door.) Husband found me writhing in pain on the floor. I was wondering about the ER.
    He bent over me and I showed him the spot below my stomach that was hurting the most, on the right side below my navel. I asked if he could feel the “log” in my intestine, and he could. He started massaging the area. After maybe 4 minutes, the pain left, and I was able to get up and get dressed. (I guess it would be called an intestinal blockage.)
    I learned that day to NOT wolf food down. ….Rose


    Hi Rose and thanks for your comments.

    That’s definitely an extreme example and sounds very painful. I think the problem is the low level intestinal damage that is being done almost daily in the way some people rush down their food.

    All the best,



Loved your advice. I’ve been trying to tell my 16 y.o. son to slow down while eating to prevent excessive stomach pains, bloating & gas. Your article is straight to the point! Hopefully, he will now see the importance of this with your detailed info. Thanks.


    Thanks for your positive comments Sheila.


Great explanation and I am going to try your advice. I spent 30 years in the police and became used to eating really fast as we were always required to attend emergency calls which often interrupted meal breaks. Its such a bad habit and I need to break it.


This is a great blog. I have always been racing against time when eating, and no wander I have been a gas problem. Why the rush? This is very insightful.


This writing saved my life. I had to make a thesis in this topic and this article was the most helpful I could found in the whole internet. Thanks a lot for this great job!


    Thanks for the positive comments. Really glad it helped.


Normally I don’t read post on blogs, however I
would like to say that this write-up very compelled me to check out and do
so! Your writing style has been surprised me. Thanks, quite great


    Thank you for the positive comments.
