When people think of their favorite fruits they may imagine the classics, bananas, apples, oranges, but tomatoes actually may be the most popular fruit in terms of production.

Cooked or raw, as a sauce, a juice or a paste, the tomato is incredibly popular. With at least 170m tonnes of tomatoes being produced every year, the tomato tops mangoes and even bananas.

"Tomatoes are high also high in Glutamate which is an amino acid, one of the building blocks of protein. And protein is essential to the building and running of every cell in our bodies." Dr Michael Mosley explained.

"So, when you bite into a tomato or savour the taste of tomato paste on your pizza, what your taste buds are really doing is telling you is to eat this food because it is rich in glutamate, which will help keep you healthy and strong."

"And that, I think, helps explain the tomatos universal popularity."
