Let’s move towards the answer.

Can Tomatoes Cause Bowel Problems?

Tomatoes are healthy, have many vitamins and minerals, and are good sources of antioxidants (lycopene) and other phytochemicals. Some people may experience IBS symptoms when they eat tomatoes.

Tomatoes Trigger IBS

Irritable bowel syndrome, also known as IBS, is a common disorder that millions worldwide experience daily.

IBS can impact your quality of life. Most people don’t understand how to deal with this disorder.

IBS symptoms include constipation, diarrhea and bloating. Many people feel worse after eating but cannot identify the culprit.

Many people have said that tomatoes make them feel worse, especially with bloating and diarrhea.

I was intrigued by the possibility that tomatoes might worsen IBS symptoms.

Also, IBS sufferers may tolerate small amounts of tomatoes but might feel bloated or have diarrhea if they consume large quantities.

It is also essential to consider whether tomatoes are consumed in raw, cooked, or processed forms like ketchup.

How Tomatoes Can Effect Bowel?

Following are some reasons and the ways tomatoes can cause bowel problems.

High Histamine Food

Tomatoes contain high levels of histamine. People who are sensitive to high histamine foods can experience allergic reactions. The symptoms include sneezing and tongue swelling. Shortness of breath, nausea, vomiting, diarrhea, bloating, stomach pain, and gut symptoms such as food sensitivity, diarrhea, bloating, and abdominal pain. According to the studies, tomatoes can cause high levels of histamine. If your body cannot process histamine, it may trigger an allergic reaction. This can, in some cases, lead to IBS symptoms.

High Acid Food

Tomatoes can cause stomach irritation and acid reflux problems in some people. Acid reflux can be caused by tomatoes, which are high in citric acid and malic acid. Acid reflux can also cause symptoms such as bloating and abdominal pain. In some cases, it can even lead to diarrhea. You may also read; Do Tomatoes Cause Acid Reflux?

High FODMAP

FODMAP is a fermentable oligo, di-, monosaccharides, and polyol. These carbs are difficult to digest and can sometimes contribute to IBS symptoms. Tomatoes are low-FODMAP food. There are many ways to increase the FODMAP value of tomatoes. One of these is tomato ketchup.

Different countries produce ketchup in different ways. Monash University conducted research and compared ketchup from Australia and the USA. They concluded that Australian ketchup was low FODMAP, but not the ketchup from the USA.

Most US ketchup is made with high fructose corn syrup, sucrose, and therefore high FODMAP. We also know that high-FODMAP foods can trigger IBS, so tomatoes could be another reason to trigger IBS.

Tomato intolerance

These delicious fruits can be a problem for some people. Because tomatoes contain too much acidity and are greasy, they can cause diarrhea. Salmonella can also be present in tomatoes, which can cause stomach upset if consumed in large quantities. If you haven’t ruled out other medical conditions that may be causing the symptoms, you can always take the Intolerance test.

Nightshades

Nightshades also include tomatoes. Because of concerns about nightshades’ association with autoimmune diseases, they have recently been in the spotlight. These claims mostly revolve around substances found in nightshades, such as alkaloids.

Tomatoes contain an alkaloid called Solanine, which is believed to repel insects.

People who consume large amounts of them can experience gut reactions or other symptoms. While some patients feel better if they avoid nightshades, not all do.

Tomatoes Can Cause Bowel Problems: So, How to Avoid It?

This is how tomatoes can cause IBS symptoms such as diarrhea and bloat. Sometimes, IBS can even be caused by IBS.

Although I don’t advocate for everyone to stop eating tomatoes, I believe they have many health benefits. I believe those with IBS who have not identified their trigger foods can try eliminating tomatoes to see if they feel better. This trial should last for 3-4 weeks to see if you notice any improvement in your symptoms. You can also find a recommended IBS Diet Plan.

Tomatoes can be very versatile, and even though this is a good thing for IBS, it can also make them a double-edged weapon. Tomatoes are the main ingredient in many processed foods like pizza sauce, ketchup and marinara. Tomatoes are safe for IBS sufferers (who are not allergic or intolerant to tomatoes) and low in FODMAPs.

However, they can trigger IBS symptoms in those who eat processed foods. Sauces and other processed foods that contain tomatoes can also contain garlic, sugar, onions, and other ingredients high on the FODMAP List, which can cause IBS symptoms to flare up whenever they are consumed.

The above analysis shows that tomatoes can cause IBS symptoms but not always. Fresh tomatoes are safe to eat as they contain many nutrients, but only moderately. If they don’t cause severe symptoms, you can eat them. You should limit the number of canned tomatoes and tomatoes in ketchup or other sauces that cause IBS symptoms to flare.

If even the slightest exposure to fresh tomatoes causes IBS symptoms, it is best to avoid them. To determine which one you are suffering from, you can take the Allergy & Intolerance Test. Talk to your doctor once you have a clear picture. They will be able to give you suggestions on what foods to eat in place of tomatoes and which foods to avoid so that you don’t get severe symptoms.

You can avoid sauces that cause IBS flare-ups by looking for sauces with low FODMAPs. If you love sauces, there is no need for you to cut them out completely.
