Why Does Red Sauce Hurt My Stomach?

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.

Why does spaghetti make me feel sick?

Some elements in pasta may cause some medical disorders to flare up, resulting in stomach discomfort. If you have a known food allergy, eating pasta could cause an allergic reaction. Some pastas contain eggs, wheat, and soy, which can aggravate intestinal irritation and irritate your stomach. Celiac disease or gluten intolerance can also cause stomach pain after consuming pasta. Gluten is a protein that is present in most pasta. After eating pasta, those who are gluten intolerant will have a variety of intestinal symptoms.

Why does the sauce in pasta make my stomach ache?

Tomatoes and heartburn Tomatoes may be loaded with beneficial compounds like lycopene, but Chutkan warns that they are also very acidic and may give people who are prone to heartburn indigestion. Daniel Mausner, MD, suggests that a sour ball could be the acid antidote.

What causes tomato sauce to make me sick?

Malic and citric acids, both of which can cause the stomach to create too much gastric acid, are abundant in tomatoes and tomato-based products. Tomatoes can cause your stomach’s acid to rise to a point where it pushes back up your esophagus. The acidity of tomatoes cannot be sufficiently reduced by cooking them to prevent acid reflux, so the next time you make pizza sauce, consider making some fresh pesto instead, and try to reduce (or completely eliminate) tomatoes from your diet.

What gives me gas when I eat red sauce?

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.

What causes gluten intolerance?

It’s unclear what exactly causes gluten sensitivity. According to some research, some people may not be sensitive to gluten but rather to a specific carbohydrate that is present in many meals. Their bodies don’t properly absorb the carbohydrates. They become ill when it ferments in their digestive tracts.

According to additional study, wheat may have an impact on certain people’s digestive tract lining. The majority of the time, this lining prevents bacteria from escaping your intestines. However, the lining might not function properly in those who are intolerant to gluten, letting bacteria to enter their blood or liver and triggering inflammation.

Can stomach problems be caused by tomato sauce?

Citrus fruits including lemons, limes, oranges, and grapefruit are acidic and can irritate the stomach lining, leading to digestive issues. Tomato sauce is also acidic. Many individuals are unaware of how acidic carbonated beverages are. Avoid eating meals that are acidic if you have an upset stomach, advises Krevsky.

What signs of a tomato sensitivity are there?

Symptoms of Tomato Sensitivity

  • Bloating.
  • stomach pains.
  • Nausea.
  • Diarrhea.
  • Rheumatoid bowel syndrome (IBS)
  • acne or skin rashes.
  • painful joints

Can IBS consume spaghetti sauce?

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.

How can tomatoes be made to neutralize stomach acid?

Pasta and tomato sauce are inherently acidic foods. In order to combat this, you must include naturally alkaline substances to lower the PH and aid in neutralizing the acid in the diet. Without significantly altering the Low-Acid Marinara Sauce’s flavor or appearance. Garlic is alkaline, but because many people find it annoying, you can lessen or even leave it out of the dish.

I’m just a cook; I’m not a doctor, so take this advice with a grain of salt. If you have any questions about any of these ingredients or recommendations, speak with your doctor.

Here are some of my tips for a Less Acidic Sauce and some foods that neutralize stomach acid.

  • For a low-acid alternative to pasta made with white, wheat, or durum flour, try gluten-free pasta. Since pasta is a major ingredient, this is a simple and rapid way to start lowering the acid content of the meal.
  • I’m sorry to break the news to you, but white flour contains a lot of acid. One of the major issues with this meal hurting your stomach is garlic knots, toast, bread, etc. The garlic bread that is best for sensitive stomachs is one that is gluten-free.
  • Carrots have a mediocre alkaline pH. The flavor is unaffected by the addition of 3/4 cup of finely shredded carrots, and once the sauce is simmered, they blend in with it.
  • Despite having a very low alkaline level, celery has a distinct flavor. The flavor is unaltered when I add 1 celery stalk that has been coarsely shredded.
  • pristine garlic Although it is technically moderately alkaline, those with sensitive stomachs may find the pungency of fresh garlic and onions to be upsetting. If a recipe calls for powdered garlic and onions, you can try using those instead to see if your specific gastrointestinal issues are alleviated. It is indicated in the recipe as optional.
  • Low alkalinity describes mushrooms. Once cooked, 8 ounces of mushrooms that have been finely chopped or pureed will vanish into the sauce.
  • Flat-Leaf Due to its mild alkalinity, parsley makes a fantastic side salad ingredient and garnish.
  • Since water is required to thin the sauce and mineral water is quite alkaline, you might as well add it.
  • Use apple cider vinegar for your salad dressing because it has a lower acidity than other varieties of vinegar. Additionally, incorporate some of the parsley, celery, mushrooms, and carrots into your salad while you’re at it.
  • Avoid House Dressings: I’m sorry to be the one to inform you, but Ranch dressing, most vinaigrettes, French, House, Blue Cheese, etc. are all acidic. If you have a sensitive stomach, it’s a good idea to investigate the dressings you choose to use.
  • soda bread. Baking soda is the only ingredient used in many “low-acid” Marinara Sauce recipes to lessen the acidity. It takes much less effort and is a terrific easy fix. This approach is only slightly foamy, which I don’t enjoy, so add it early in the cooking process so it has time for the bubbles to burst. In the long run, I believe including these additional nutritious options—such as carrots, celery, apple cider vinegar, etc.—will be healthier for you. Therefore, 1 1/2 teaspoons of baking soda will assist in balancing the acid.
