We’ve all been there: eating a delicious Sunday roast with the family when all of a sudden, someone farts. Even though going to the bathroom is a normal bodily function, it can be embarrassing when it happens when you don’t want it to. But why do some foods, like roast beef, give you gas? Is meat really to blame for flatulence? Let’s look into the science behind farting, problem foods, and how diet affects digestion.
Why Do Humans Pass Gas? A Look at the Causes of Flatulence
Farting is a natural part of the digestive process, The average person passes gas around 5-15 times per day Gas occurs when we swallow air while eating or drinking Air can also seep into the intestines while digesting food,
As food passes through the gastrointestinal tract, gut bacteria in the large intestine help break it down. During this process, fermentation occurs which releases various gases – mainly hydrogen, methane, and carbon dioxide. These gases accumulate in the rectum until eventually being passed out the other end!
- Swallowing excess air while eating and drinking
- Air entering the intestines during digestion
- Gut bacteria fermenting undigested food particles
It’s normal to pass gas, but some people have too much of it, which can be embarrassing or uncomfortable. Certain dietary triggers are often to blame when gas becomes excessive.
Do Foods Like Roast Beef Cause More Gas?
Many people claim that foods like red meat especially beef make them gassier than other foods. But what does the science say? Here’s a look at how roast beef and other meat products may be contributing to flatulence issues
Fatty Meats
Meats that are higher in saturated fat, like prime rib and ribeye steak, are more common than meats that are lower in saturated fat. Fat takes longer to digest, so fatty acids that haven’t been broken down stay in the intestines. This provides more substrate for bacteria to feed on and produce gas.
Furthermore, fatty foods may affect stomach emptying. When food remains in the stomach longer before being released into the small intestine, more gas-producing fermentation occurs.
Amino Acids in Meat
Meats contain substantial amounts of the sulfur-containing amino acids methionine, cysteine and taurine. During digestion, gut bacteria produce hydrogen sulfide and other sulfur compounds from these amino acids.
Hydrogen sulfide is one of the main culprits behind foul-smelling flatulence. The rotten egg odor tends to be more noticeable with meat-heavy meals compared to plant-based foods.
Resistant Starches in Roasted Meat
Cooking methods can alter the digestibility of meat. High temperatures break down proteins making them easier to digest. However, roasting and grilling meats at high heat also leads to more resistant starches on the surface.
These starch molecules resist digestion, so they ferment in the colon producing carbon dioxide and hydrogen gas. Well-done and charred meats tend to be higher in resistant starches.
Other Causes of Meat-Related Flatulence
While roast beef and other red meats may contribute to gas, other factors related to meat can also be culprits:
-
Processed meats like deli roast beef contain added starches, sugars, and nitrates that may encourage fermentation.
-
Marinades, rubs and sauces can introduce flatulence-triggering ingredients like garlic, onions, beans, sugars, etc.
-
Cooking methods besides roasting/grilling can increase digestibility of meat and reduce gas. Stews, braises, and slow cooking break down fiber.
-
Eating too much meat in one sitting provides more substrate for fermentation so meat should be balanced with vegetables.
-
Individual intolerances to meat proteins or seasonings may cause excessive gas for some people.
Tips for Preventing Roast Beef Gas
If you experience a lot of flatulence or digestive issues after eating roast beef, don’t fret – some simple diet and lifestyle changes can help reduce gas production:
-
Choose leaner cuts of beef with less marbling like sirloin tip or top round.
-
Limit portion size to 4-6 oz of meat per meal and balance with non-gassy vegetables like carrots, zucchini, spinach.
-Cook meat thoroughly but avoid charring the surface which creates more resistant starches.
-
Limit added fatty sauces and seasonings that may trigger gas.
-
Slow cook meat in stews and braises instead of high heat dry cooking methods.
-
Try digestive enzymes like Alpha-galactosidase to help break down gas-producing oligosaccharides.
-
Activate friendly bacteria with prebiotic foods like garlic, onion, asparagus that support healthy digestion.
-
Reduce other high gas foods like beans, dairy, wheat around the same meal.
-
Stay hydrated and avoid drinking through a straw which causes more swallowed air.
When to See a Doctor About Digestive Issues
Occasional gas and bloating after eating meat or other foods is normal. But if you experience chronic symptoms like diarrhea, abdominal pain, and excessive flatulence, it’s best to get evaluated by a gastroenterologist.
You may have an underlying condition like:
- Irritable bowel syndrome (IBS)
- Small intestinal bacterial overgrowth (SIBO)
- Lactose intolerance
- Food allergy or intolerance
- Celiac disease
- Inflammatory bowel disease (IBD)
Testing can identify if you have food sensitivities, gut microbiome imbalances, or other GI issues causing persistent digestive problems. Treatment may involve dietary changes, stress management, probiotics, and medications to get your gut back on track.
The Takeaway – Moderation Is Key
While foods like roast beef, dairy, beans and vegetables often get a bad rap for causing gas, the real culprit is usually overdoing it on these items. The amount you eat, how you prepare meats, and your individual colon bacteria all affect how gassy a food may be.
Rather than eliminating meats, focus on proper portion sizes as part of a balanced diet. If you have excessive flatulence or discomfort after eating beef, try switching cooking methods or meat choices. And be sure to get evaluated for digestive issues if problems persist. With some simple dietary tweaks and care for your gut microbiome, you can keep enjoying Sunday roasts while minimizing unwanted toots!
Jerusalem artichoke GastronautTV explains why Jerusalem artichoke causes excessive wind
Jerusalem artichoke, also known as sunchoke, is a starchy edible root. It contains high levels of inulin, a very gassy non-digestible carbohydrate that is fermented by gut bacteria. It has such potent flatulence powers that professional chefs and gardeners have nicknamed it the fartichoke.
That good bacteria in your gut turn into butyrate, a short-chain fatty acid that keeps the lining of your gut healthy, is called a prebiotic. It also helps the body absorb magnesium and calcium, which are micronutrients that are good for bones, nerves, muscles, and more.
☝️QUICK FIX Avoid or consume very small portions of Jerusalem artichoke when it’s in season.
Cabbage, broccoli, cauliflower, and other cruciferous vegetables are common foods that cause flatulence and gas. These plants release sulfur-containing organic compounds, called glucosinolates, when the leaves are cooked and/or chewed. Common cruciferous vegetables include:
- Broccoli
- Cabbage
- Cauliflower
- Dark leafy greens (kale, collard greens, mustard greens, etc.)
- Kohlrabi
- Radish
- Rutabaga
- Turnips
Glucosinolates (and the products of their breakdown) have health-promoting effects for the human body. Glucosinolates are changed into sulfate and ferrous ions by many different types of gut bacteria. These can then be broken down into hydrogen sulfide (which smells like rotten eggs) and sulfur.
Glucosinolates are good because they feed probiotic bacteria like Lactobacillus and Bifidobacterium that live naturally in our guts. On the other hand, having too many sulfate-reducing bacteria in the gut, such as Desulfovibrio, can make more hydrogen sulfide, which makes farts smell really bad.

Humans fart 5–15 times per day. Even though farting is perfectly normal, excessive wind can lead to embarrassing situations and lingering smells that make socialising difficult or impossible.
Luckily, changing what you eat can stop you from having too much gas. This is because gas is often caused by certain foods that are fermented by bacteria in the large intestine. Microbes release gas as they break down undigested food particles. Eventually, enough gas accumulates and is released by the anus.
In particular, high-fiber foods like vegetables and legumes feed good bacteria in the gut, which turns them into helpful substances like vitamins and prebiotics. As a side effect, this can cause gas. This is why going vegan or vegetarian can make people gassy.
Foul-smelling flatulence is caused by hydrogen sulfide, which makes farts smell like rotten eggs or cabbage. Some gut bacteria, like Desulfovibrio and Desulfobulbus, produce hydrogen sulfide from amino acids in food, like cysteine and methionine.
Digestive health problems can also cause bad wind and constant farting. Lactose intolerance, which can happen at any age, irritable bowel syndrome (IBS), and celiac disease that hasn’t been treated can all cause too much gas.
