Pizza Hut has topped a new Pizza League of Shame for having the fattiest, smallest and least tasty dishes on the High Street.
All six pizzas tested by experts in the Which? survey were high in salt
Food experts from the Good Food Guide have drawn up a list of the country's best and worst margheritas after visiting six chain restaurants.
The reviewers discovered that the lowest in fat - from Pizza Express - also scored the higest for taste.
Consumer magazine Which? sent reviewers to examine pizzas at Pizza Hut, Pizza Express, Zizzi, Prezzo, Ask and Frankie & Benny's.
All six dishes were rated "red" according to the Government traffic light system for saturated fat and salt.
Pizza Hut pizzas were the smallest on average but also the highest in total fat.
Some of the chains we've investigated are serving meals that are so high in fat and salt - and in some cases, so unappetising - that they're taking the pizza.
They contained 70% of a woman's daily recommended maximum amount of saturated fat.
The pizza at Zizzi had the highest level of salt, and at Prezzo the highest level of saturated fat.
On average, all the pizzas contained more than half of an adult's recommended daily maximum amount of salt.
Pizza Hut and Frankie & Benny's scored the lowest for pizza taste and quality and restaurant experience - 11/45.
The reviewers said Pizza Hut was "best avoided".
Worst tasting - Pizza Hut
Pizza Express came top for taste - 30.5 out of 45 - earning praise for "flavoursome pizzas with good quality, well-balanced ingredients".
They were followed by Ask which scored 27 out of 45.
Zizzi came a close third with 26.5, and Prezzo scored 25.5.
Editor of Which? Martyn Hocking said: "Some of the chains we've investigated are serving meals that are so high in fat and salt - and in some cases, so unappetising - that they're taking the pizza."
Meanwhile another Which? feature reveals that children who eat at fast food chains can consume nearly half their recommended daily calories in one sitting.
Youngsters who went to KFC ate two-thirds of their guideline maximum daily salt intake in one meal.
Children aged between 11 and 14 had half the recommended amount of sugar at McDonald's and Burger King.
