Tomato

1. Gastro-intestinal Effects :Tomatoes are acidic vegetables, so eating too many of them can aggravate preexisting medical conditions, such as gastroesophageal reflux disease, or GERD, also known as acid reflux -- a condition in which the digestive acids in your stomach rise and leak through the muscle acting as a valve between your stomach and esophagus, burning your esophagus. Tomatoes, especially in great quantities, can make this worse. According to the Mayo Clinic, the seeds in tomatoes can also aggravate diverticulitis, by lodging in the diverticula, small pouches formed in your digestive tract, causing inflammation and infection.
2. Vitamin Overdose :It is possible to overdose on certain vitamins and nutrients if you consume large amounts of tomatoes in high concentrations. One medium-size tomato contains 1,025 IU of vitamin A, just under half of your daily recommendation of vitamin A. If you were to eat 10 tomatoes in a day, you would exceed your vitamin A upper limit, which could lead to nausea and headache, according to the Linus Pauling Institute. A medium tomato also contains around 17 mg of vitamin C, about a tenth of your upper limit. Eating too many tomatoes and causing a vitamin C overdose might lead to the development of kidney stones.
3. Hypersensitivity :A tomato allergy is a type 1 hypersensitivity to tomatoes. Type 1 allergies are commonly known as contact allergies. When a person with this type of allergy comes into contact with an allergen such as a tomato, histamines are released into exposed areas such as the skin, nose, and respiratory and digestive tracts. In turn, this causes an allergic reaction.
4. Cross-reaction :Despite the fact that tomatoes and tomato-based products are some of the most heavily consumed foods in the western diet, tomato allergies are extremely rare. An individual with a tomato allergy is also prone to allergic reactions with other nightshades, including potatoes, tobacco, and eggplant. Often, people with a tomato allergy will have a cross-reaction to latex as well (latex-fruit syndrome).
