9. Bacterial Contamination
Like other produce, tomatoes may become contaminated with foodborne pathogens such as Salmonella, E. coli, or Listeria. Fruits and vegetables may become contaminated with bacteria at the farms where they are grown, during transport, in a warehouse, or even in your own kitchen. To decrease the risk of coming down with a foodborne illness, keep fresh fruits and vegetables in the refrigerator to slow bacterial growth. Then, scrub tomatoes and other produce under running water to wash away surface germs before consuming. Keep raw meats separate from fruits and veggies to prevent cross-contamination with bacteria.
8. Kidney Stones
Kidney stones are painful masses that can build up in your kidney and cause a blockage. According to the Cleveland Clinic, the majority of these stones are made up of calcium oxalate. Some patients who are susceptible to kidney stones may test high for oxalates. In this case, they may be able to prevent the formation of new kidney stones by eating a diet low in oxalates. While a single tomato may not be high in oxalate, tomato soups or tomato sauces may contain a high concentration of oxalates. Therefore, if you are on a low-oxalate diet, you may want to avoid tomato products.
7. Kidney Disease
Tomatoes may also cause a problem if you suffer from kidney disease. If your kidneys are unable to process sodium and potassium adequately, your doctor may recommend a low-sodium, low-potassium diet. While tomatoes themselves are not high in sodium, tomato products such as ketchup, soups, and tomato sauce are often high in salt. Meanwhile, tomatoes are higher in potassium than many other fruits and vegetables. If you suffer from kidney disease, talk with your doctor to find out if you have any dietary restrictions.Related: 9 Habits That Hurt Your Kidneys
