Discover the 12 side effects of eating too many tomatoes.

Scientifically called Solanum Lycopersicum, the tomato belongs to the Solanaceae family.

Tomatoes originated in Central and South America. In Mexico, they were first used in the food and eventually spread around the world.12 Serious Side Effects of Eating Tomatoes.


Today, tomatoes are consumed in various ways: raw, cooked, and as an ingredient in many dishes, sauces, drinks, and salads (it is unlikely that tomato is harmful)

But now comes the big question:

Why Tomatoes Can Be Bad For You?

What if I eat a tomato every day? Although they are generally safe for consumption ( negative properties of tomato ), daily or frequent use can cause complications in some people. Some of the problems that tomatoes can cause include acid reflux, intolerance effects, muscle aches, etc.

Even the leaf of the tomato plant can be unsafe. In large quantities, it can cause vomiting, dizziness, headache, and, in severe cases, even death


Another major factor contributing to this dark side of tomatoes is lycopene, the same compound that, surprisingly, is also responsible for its benefits.

Lycopene In Tomatoes

Lycopene is safe in most cases. But lycopene supplements may not be safe during pregnancy. Lycopene can also aggravate the symptoms of prostate cancer.

Lycopene should be used with caution in patients with stomach ulcers and other stomach problems. The compound can also cause low blood pressure. People taking blood pressure-lowering medications should stay away from lycopene.

Lycopene can also increase the risk of bleeding and people with bleeding disorders should avoid it.

Other side effects related to taking lycopene are chest pain, accumulation of fat under the skin, indigestion, and worsening of hot flashes.

Lycopene was also found to interact with certain cancer chemotherapy agents. Therefore, people on cancer treatment should be careful.

Side effects of eating too many tomatoes

Below are the side effects of tomatoes:

The main contradictions of eating a lot of tomatoes DO have side effects that can include:


1. Acid reflux/heartburn

Tomatoes are highly acidic, which makes them prone to causing heartburn.

Tomatoes are full of malic and citric acids and can cause the stomach to produce excess gastric acid (which is responsible for the breakdown of food).

When the volume of the acid increases, it is forced to flow into the esophagus, causing symptoms. Even cooking tomatoes may not be of much help.

Tomatoes and ketchup are also listed as a couple of foods that can cause reflux.

Tomatoes can also make GERD (gastroesophageal reflux disease) symptoms worse. According to the University of Maryland Medical Center, it’s best to avoid acidic foods like tomatoes to avoid acid reflux symptoms.

2. Allergies and infections

Symptoms of a tomato allergy most often occur immediately after the fruit is consumed.

These include hives, skin rashes, eczema, coughing, sneezing, itchy throat, and swelling of the face, mouth, and tongue.

According to a Polish study, tomatoes contain a compound called histamine that can cause certain allergic reactions.


Tomatoes can also cause allergic contact dermatitis, where the skin becomes very irritated and inflamed after touching the fruit.

Tomatoes can also make your lips itch. Another allergic reaction related to tomatoes is a red patch around the eyebrows and eyelids.

3. Kidney problems

According to a report published by the US Department of Health and Human Services, people with advanced chronic kidney disease should limit their intake of potassium, a mineral-rich tomato.

People with severe kidney problems should also limit their intake of tomatoes, as they contain a lot of water.

High levels of potassium in the blood, which is one of the causes of kidney disease, could be treated by avoiding tomatoes or tomato sauce, or anything made from tomatoes.

Ketchup is also high in oxalate, which is another reason susceptible people should avoid it.

4. Irritable bowel syndrome

Tomatoes, given their irritating skin and seeds, can be one of the reasons for irritable bowel syndrome. And if you’re already suffering from IBS, tomatoes can lead to bloating, too.

Tomatoes are also one of the most common food allergens that can cause intestinal problems.


5. Tomato gives diarrhea

Diarrhea can occur in individuals suffering from tomato intolerance.

According to a report published by Longwood University, tomatoes are fatty and acidic and should be avoided during diarrhea.

And according to another report from the University of Minnesota, tomatoes may be a source of an organism called salmonella that causes diarrhea.


6. Excess sodium

Be sure to choose lower sodium versions of tomato sauce, as most sauces are high in sodium.

Even tomato soup can have too much sodium. Just one cup of soup can contain between 700 and 1,260 mg of sodium. Canned tomatoes can contain 220 mg of sodium for every half cup.

7. Lycopenoderma

We know that tomatoes are excellent sources of lycopene. This can also be a nightmare.

Excessive intake of lycopene can cause lycopenoderma, which is the deep orange discoloration of the skin. This may not be a health threat, but it is surely not very attractive to watch.

Lycopenoderma can also occur with excessive consumption of lycopene supplements. But don’t worry, the condition is reversible.


8. Urinary problems

Acidic foods like tomatoes can irritate the bladder and cause urinary incontinence. Tomatoes can also cause bladder symptoms and, in certain cases, cystitis (a burning sensation in the bladder).

9. Body aches

When the body’s immune system reacts to the proteins in tomatoes, a compound called histamine is released into the tissues (we’ve already talked about this). This compound can cause swelling and pain in the joints.

Tomatoes also contain an alkaloid called solanine, which builds up calcium in tissues and causes inflammation.

Eating too much tomato can also increase uric acid levels, and this can lead to gout.

Tomatoes can also trigger arthritis conditions in some people, causing pain.

10. Respiratory problems

People allergic to tomatoes may have trouble breathing.

We can also accuse tomatoes of being conducive to mold growth, and molds, according to the United States Department of Agriculture, can cause allergies and respiratory problems.

11. migraine

Tomatoes are known to trigger migraines. According to experts, you can prevent migraines 40% of the hour simply by making some dietary changes.


According to an Iranian study, tomato is a powerful migraine trigger.

12. Acute gastrointestinal disorder

Since tomatoes are highly acidic, they can cause acute stomach upset if you are already suffering from acid reflux or heartburn.

Tomatoes can also cause the stomach to produce more acid, which can cause an acute gastrointestinal disorder.

These side effects simply tell us to be careful not to consume tomatoes in excess. But that’s not all: there is another group of people who, in this regard, should practice caution more than anyone.

Pregnant and lactating women

In regular amounts, tomatoes are safe for pregnant and lactating women. However, there is insufficient evidence when it comes to large amounts. The best way to do this would be to consult your doctor.

Speaking of lycopene in this context, there is no evidence. Therefore, refrain from taking lycopene supplements.

Tomato, especially sauce, has a strong flavor and can get into breast milk. This can make the baby uncomfortable and irritable.

Frequently Asked Questions

Can I eat tomatoes every day?

Tomatoes contain solanine, which is a toxic alkaloid. This alkaloid is a part of the plant’s defense mechanism to make the fruit look unappealing to animals.


Although all parts of the plant contain solanine (including the fruit), the highest concentrations are found in the leaves and stems. Therefore, the consumption of tomatoes in normal quantities is not toxic.

Are Tomato Seeds Poisonous?

Usually not. But consult your doctor in this regard. Certain individuals are not allowed to have tomato seeds due to medical reasons.

What are green tomatoes?

Green tomatoes are of two types. One is the immature red tomato, and the other is the heirloom tomato variety that is originally green.

Heirloom tomatoes have vertical stripes, are soft when pressed, and taste very similar to ripe red tomatoes. Unripe red tomatoes look green, feel tougher, and taste tangy.

Can you eat raw tomatoes?

Yes. You just have to check the acidity. If you are suffering from acid reflux or any other gastrointestinal problem, raw tomatoes are not advised.

Is the tomato leaf poisonous?

There is not enough evidence in this regard. To be on the safe side, avoid consuming in large quantities. And consult your doctor.

Are canned tomatoes dangerous?

Yes, in the long run. Any canned food is considered dangerous. This is because the inside of these cans is covered with bisphenol-A or BPA, which can pose a health risk. Even otherwise, canned tomatoes are high in sodium, and that’s not healthy.

Can tomatoes be applied to the face?

Yes. They benefit your skin in many ways: they tone your skin, improve texture, and aid in exfoliation. But again, heartburn is the problem. If you are allergic to tomatoes, don’t use them.


What is the glass tomato? Does it have side effects?

Crystal Tomato is a food supplement and food additive that contains natural tomatoes and L-cysteine (an amino acid). It is approved by the FDA. But it could cause side effects in people who are allergic to tomatoes.

Do dried tomatoes have side effects?

The main concern of sun-dried tomatoes is their relationship to hepatitis. Sun-dried tomatoes can cause serious liver damage, and this depends on the brand that sells them. As of now, we don’t know which brand is the culprit.

How many tomatoes can I eat in a day?

About 1/3 cup of tomatoes in a day. But this amount is specific to the individual. Otherwise, 1/3 cup of tomatoes in a day should be fine.

These side effects do not mean that you will shed tomatoes right away. They have numerous benefits. What we say is to be wary of side effects and not consume them in excess.
