Tomatoes are sweet and sour, easy to cook and can be eaten raw and cooked. Whether it's stewed beef with tomatoes, scrambled eggs with tomatoes, or tomato sauce and ketchup with Western food, it always adds to the delicacy. But for some people, eating too much and too often can have obvious side effects on the human body.

Tomato allergist. Although many people do not know, tomatoes are indeed one of the known allergens. It can cause sneezing, eczema, rash and other problems in susceptible people, as well as different symptoms such as red eyebrows, eyelids, itchy throat and swollen mouth and face. In some cases, even exposure to tomatoes can cause allergic reactions (e.g. dermatitis) in some people. According to the European Food Safety Agency, eating too much tomatoes can cause accumulation of certain metal elements in the body, which can have a negative impact on some sensitive people. For example, nickel is one of the common heavy metals in contaminated tomatoes. Short-term exposure can cause allergic reactions, while long-term exposure can affect animal development and reproduction.
People with renal dysfunction. The U.S. Department of Health and Public Service says people with kidney problems should reduce potassium intake, while tomatoes contain high levels of potassium. There are also concerns that tomatoes and their products, especially oxalic acid in tomato paste, are also potentially risky compounds. When ingested in large quantities, they bind to calcium in the body and may adversely affect the formation and recurrence of kidney stones. However, the impact remains to be further confirmed by epidemiological studies.
People with gastroesophageal reflux disease/heartburn. Gastroesophageal reflux disease is mainly related to dietary habits. Eating tomatoes and processed products is one of the main causes of gastroesophageal reflux disease. In this state of illness, a large amount of gastric acid returns to the esophagus, causing a sour taste and burning sensation in the chest and throat. Citric acid and malic acid in tomatoes are likely to be the main causes of disease in susceptible individuals and high-frequency tomato consumers.
Irritable bowel syndrome. Irritable bowel syndrome (IBS) is a common gastrointestinal disease. Its symptoms mainly include abnormal defecation, abdominal distension, abdominal pain and frequent attacks of constipation or diarrhea. Poor dietary habits are the most important factors causing the disease. Tomato sensitization may cause intestinal problems in some people. At the same time, the skin and seeds of tomatoes may irritate some people's intestines and stomach, leading to abdominal distension and diarrhea.
People prone to stomachache and abdominal pain. Immature green tomatoes contain alkaloids, solanine, which is toxic to help plants resist insects, fungi and bacteria. The content of alkaloids decreased with the maturation of tomatoes. But for some sensitive people, eating a lot of tomatoes can still cause gastrointestinal discomfort and pain.
Persons with urinary incontinence and cystitis. Sour foods, such as fruits, vegetables and beverages, are often considered as potential bladder irritants. For some sensitive people, it may increase the risk of urinary incontinence, including sour tomatoes.
Overconsumption of certain foods, including tomatoes, chocolate, caffeinated beverages and artificial sweeteners, can cause cystitis and exacerbate symptoms of bladder disease. Studies have also shown that tomatoes and their processed products have adverse effects on painful bladder syndrome.
Migraine. Diet is considered to be one of the inducing factors affecting the onset and aggravation of migraine. In a case-control study of 170 migraine patients, the consumption of several vegetables, including tomatoes, was significantly higher in the case group. Some experiments also showed that eating tomatoes had a significant effect on the incidence of migraine.
People who worry about skin discoloration. Tomato is a rich source of lycopene, lycopene is an effective antioxidant. However, the consumption of large quantities of tomatoes can lead to excessive lycopene in the blood and plasma of individuals, leading to skin discoloration and redness, known as lycopene hemorrhage.
