Why Does Spaghetti Sauce Give Me Gas?

Although most of us prefer not to discuss it, almost everyone experiences bloating and/or gas. For the majority of people, this is just a typical, healthy, and generally unproblematic aspect of life; it is an inevitable outcome of how the body digests and breaks down food.

However, some people might discover that particular foods cause them to feel uncomfortablely bloated or gassy. Stomach distress, which in some circumstances can even be painful, might come along with this. Many people might not be aware that a certain dish is the problem or they might feel too ashamed to bring up the matter. As a result, more discomfort will result from eating the problematic item.

We’ve compiled a list of unexpected foods that can cause bloating and/or gas if you suspect a food may be the source of your issues but aren’t entirely sure what it is. Look over the list below.


Apples are a great source of fiber, which is important for promoting a healthy digestive system. High-fiber meals like apples, however, may cause excessive gas and bloating in certain people. This occurs more frequently in those who consume low levels of fiber because their digestive systems are unaccustomed to the quick rise in body weight.


Around the world, bread is a basic food that is generally well tolerated by most people. But some people might discover that eating bread makes them bloated and gassy. If you experience these symptoms even after consuming a tiny amount of food, you may have a wheat or gluten intolerance, which puts stress on the gut and digestive system.


Fructose, a natural sugar found in many fruits and vegetables, is present in high concentrations in onions. Some people are unable to digest and absorb the sugar correctly. Fructose can enter the lower bowel and provide a feast for the bacteria that reside there if it is not properly absorbed into the bloodstream. Methane is created as the bacteria “eat away on the fructose; this can result in bloating, gas, and cramps, as well as poor breath.” This combination is not good!


These adorable tiny fruits from the hedgerow, though they taste great and are rich in antioxidants, are also bursting with polyols. Carbohydrates called polyols, usually referred to as “sugar alcohols,” are frequently employed in the creation of artificial sweeteners. Polyols are less calorific than sugar, but they take longer to digest and linger in the system for a longer period of time. This indicates that they are occasionally not completely absorbed by the body, leading to gas and bloating.


Although garlic is a powerful natural antibiotic with many health advantages, some people may experience flatulence as a side effect. Whether roasted or stir-fried, cooked garlic is significantly less likely to result in gas and bloating.


Milk includes several proteins, including casein and whey, in addition to calcium and vitamin D. If the digestive system is not operating at its peak capability, the proteins may be challenging to break down. This may explain why you feel winded and bloated after eating a cheese sandwich and drinking a coffee.


Nuts take a while to thoroughly digest because of their high fat and fiber content. The likelihood of experiencing gas and bloating is significantly increased because they take a long time to move through the digestive system. Additionally, nuts contain tannins, which some people may find nauseating.

Artificial Sweeteners

Artificial sweeteners are a typical addition to many food and drink items on the market today, despite not being a food in and of itself. Artificial sweeteners may be hard for the body to digest, which increases the risk of gas, bloating, and gastrointestinal issues. Even the warning that excessive consumption may have “laxative effects” can be found on many items containing sweets. In this post, we go into further detail on artificial sweeteners.


The tomato fruit contains a lot of organic acids. Because tomatoes have a high acid content, they may cause some people to produce more stomach acid, which may cause bloating and gas. Try removing the peels after boiling the tomatoes in water the Italian way. This will make it easier for the body to digest the tomatoes.


Avocados, like nuts, are loaded with healthy fats and vital fiber. They also have a high polyol content, which speeds up digestion and increases the risk of producing gas. Frequently, eating 1/4 to 1/2 of an avocado is okay but the entire fruit may be harmful.

It’s crucial to note that, as usual, each person will react differently to the foods we’ve included and that, when consumed in moderation, all of the foods on our list are healthy and advantageous to a diet. Some of you may even be able to chow down on a lunch of sandwiches with blackberries, avocados, and onions and feel completely great.

Say you love a bowl of spaghetti more than anything, but sadly, this hearty dish doesn’t necessarily love you back.

You are not by yourself. According to Elena A. Ivanina, DO, MPH, a gastroenterologist at Lenox Hill Hospital in New York City, spaghetti can cause gas for a variety of reasons.

Why do I feel bloated after consuming spaghetti?

Gluten, a protein found in wheat, can make some people experience bloating, gas, stomach pain, and diarrhea. Gluten can be found in bread, spaghetti, and many baked foods.

A disorder called celiac disease, which affects 1% of Americans, can be the cause of gluten sensitivity.

6% of people may have non-celiac gluten sensitivity, according to a study published in the World Journal of Gastroenterology.

Why does red sauce make me ill?

According to the Mayo Clinic, a food intolerance is a digestive system reaction to a food that is comparable to an allergy but considerably milder and not life-threatening.

Some folks simply don’t process certain foods on the FODMAP list effectively, which wrecks havoc on their GI tracts.

According to Harvard Health Publishing, FODMAPs, also known as fermentable oligosaccharides, disaccharides, monosaccharides, and polyols, are short-chained carbohydrates that include fructans, lactose, fructose, sorbitol, and mannitol. These foods are well known for making people feel ill.

Unfortunately, tomatoes are included on the FODMAP list. According to Food Intolerance Diagnostics, they contain the natural sugar fructose, which some people are sensitive to or malabsorb.

According to Ray Scott Daugherty, MD, a specialist in treating all colorectal problems, the poorly digested fructose is fermented by gut bacteria, which can cause symptoms of an upset stomach like:

  • Gas and cramping pains
  • Diarrhea
  • Constipation

Tomatoes may cause diarrhea because of poor fructose absorption, which is regarded to be one of the dietary causes for irritable bowel syndrome.

According to dietitian Kristin West RD, LDN, “Small amounts of tomatoes may not present an issue, but where some people get caught up is with canned tomatoes or other tomato-based items like ketchup and spaghetti sauce.”

According to her, “These additional goods frequently contain additives like high-fructose corn syrup or garlic, which can cause you to enter the high-FODMAP zone.”

Therefore, these elements may be to blame if you’ve ever wondered why tomato sauce makes you ill or causes you to have diarrhea. Don’t forget to read labels because tomato soups and juices may contain numerous substances that your stomach won’t tolerate.

Fix it: To minimize stomach distress and diarrhea after eating tomatoes, it’s best to have your doctor or a nutritionist assist you in creating a diet around your limits if symptoms become troublesome.

Tomatoes Contain Fructose

Among the naturally occurring sugars in fruits and vegetables is fructose. Although tomatoes are frequently used as vegetables in cooking, they are actually fruits, which accounts for their sweet flavor. For a number of reasons, tomato fructose may cause bloating.

IBS sufferers may be more likely to experience bloating after consuming fructose-containing foods. Fructose can ferment in the colon if it isn’t absorbed adequately. Inconvenient gastrointestinal symptoms including bloating, gas, and diarrhea can result from this, according to study published in Medical Hypotheses in September 2016.

Fructose intolerance can occur in some persons, even those without IBS. According to the Cleveland Clinic, this occurs when the body has trouble absorbing or breaking down the fructose found in meals like tomato products. The symptoms are similar to those of IBS, making a diagnosis challenging.

Tomatoes Are Rich in Fiber

Because they contain a lot of fiber, fruits and vegetables should be consumed in sufficient amounts. Although fiber is a crucial vitamin that many people don’t get enough of, too much of a good thing can be harmful. Your stomach may become irritated if you switch from a low-fiber to a high-fiber diet.

The majority of the fiber is found in tomato skins, which can cause bloating, according to registered dietitian Christa Brown, RDN.

The USDA estimates that 2.2 grams of fiber are included in one cup of diced tomatoes. According to the Academy of Nutrition and Dietetics, those assigned female at birth (AFAB) should strive for 25 grams of fiber day, whereas individuals assigned male at birth (AMAB) should aim for grams daily. Around 5.7 to 8.8% of your daily fiber requirements are found in a serving of tomatoes.

Fruit contains nearly 95% water by weight due to their high water content and minimal level of fiber.

Regular bowel movements are encouraged by tomatoes. These generally advantageous characteristics might cause bloating, especially if you consume a lot of tomatoes or have a low-fiber diet.

While bloating brought on by a sudden increase in fiber is frequently accompanied with intestinal gas, bloating brought on by water is normally brief.

Tomatoes Are Acidic

Tomatoes have a lot of water, but they also have a lot of acid. Consuming tomatoes could aggravate a sensitive stomach’s lining, resulting in inflammation and slight bloating.

According to Brown, tomatoes are an acidic food with a desired PH level of ≤ 4.6. “This results in a rush of stomach acids to aid in the tomato’s digestion, which produces bloating.”

However, experiencing severe bloating after eating tomatoes may be an indication of intolerance, a chemical reaction that might only happen after consuming a specific quantity of the problematic item. Tomatoes are a common cause of food intolerance, along with dairy products, chocolate, and citrus fruits. Bloating and distention can also be brought on by food intolerance.

Bloating is another symptom of indigestion, which is brought on by tomatoes’ high acidity. According to the National Institute of Diabetes and Digestive and Kidney Diseases, tomatoes and tomato-based products are high in acid, which can cause indigestion.

Tomato Skin and Seeds Contain Lectins

A family of proteins known as lectins binds to carbs. They are known to cause GI problems like bloating and nausea.

Most plants contain lectins, particularly legumes, grains, fruits, and vegetables. The Mayo Clinic states that tomatoes have higher levels of lectins. Where there is fiber, which is in the skin and seeds of tomatoes, is where the majority of the lectins are found.

The majority of scientists concur that foods strong in lectins provide nutritional benefits that outweigh any potential risks. According to the Harvard T.H. Chan School of Public Health, bloating is a minor adverse effect of diets high in lectins.

Can spaghetti sauce cause IBS symptoms?

Red sauces, such tomato and marinara sauces, are favored trigger foods for many IBS sufferers.

Fact: Red sauce is a high-FODMAP and challenging to digest food since it frequently contains sugar, onions, and garlic.

Advice: The next time you crave red sauce, think about trying one of these low-FODMAP dishes.
