Tomato Intolerance

The tomato (Solanum Lycopersicum) is a fruit of South American origin from the nightshade family now grown throughout most of the world. Despite botanically being a fruit, it is usually prepared and eaten as a vegetable.

A tomato is made up of approximately 95% water, 4% carbohydrates and less than 1% of fat and protein. Tomatoes are considered low in calories and a moderate source of vitamin C.
Tomatoes give an umami flavour to cooking and are consumed in many ways including raw in salads or cooked dishes, sauces, salads and even drinks. Tomatoes and tomato products can be found in a large number of processed foods.

Tomato allergies are extremely rare despite the increase in tomatoes and tomato-based products throughout the world. A person with a tomato allergy is also likely to experience allergic reactions with other items from the nightshade family, including potatoes, tobacco, and aubergine. Those with a tomato allergy will sometimes also have a cross-reaction to latex and latex products (latex-fruit syndrome).

Symptoms of tomato allergy include:

  Rash or hives
  Abdominal cramps
  Nausea or vomiting
  Narrowing of the throat
  Swelling of the face or lips
  Anaphylaxis (very rarely)

Tomato sensitivity

Tomato sensitivity or intolerance is where a person presents various digestive symptoms after the consumption of tomato products. A less severe condition than an allergy, this condition can still be uncomfortable and embarrassing for the individual.

Symptoms of tomato sensitivity or intolerance can include:
