It sounds almost too good to be true. A Scottish nutritionist has developed what could be the world's first nutritionally balanced pizza with a third of the recommended amount of an adult's daily requirement of vitamins, minerals, calories, protein and carbohydrate.

The pizza developed by Mike Lean, of Glasgow University and businessman Donnie Maclean has a range of toppings that incorporate nutrients such as magnesium, potassium, folates, vitamin C and A. The toppings include roasted cherry tomatoes, red peppers and sweet caramelised onions, the BBC reported.

"I researched the market and found that seaweed was an interesting new ingredient being used in artisan bread. So we used that as a way of reducing the salt level. The sodium content of seaweed is about 3.5% compared to 40% in salt. There's iodine in there, vitamin B12, all sorts of things. And the flavour is excellent as well," Lean was quoted as saying.

"If you go along to a supermarket or a restaurant and buy a meal, then somebody should have thought about it nutritionally," he said. This frustration led him to work on a variety of pizzas that would not only be tasty but also healthy.

"The way the guidelines are set out, you have 20% of your nutrients and calories from your breakfast, 30 per cent from your lunch, 30 per cent from your dinner, and an extra 20 per cent for snacks," The BBC quoted Maclean as saying.

The secret of the healthy pizzas is a recipe that allows them to pack in more nutrients into regular pizzas. They worked on reducing the salt level on the standard pizzas available in the market

As of now the pizzas will only be available frozen, preserving their nutrients. Maclean said their pizzas are slightly more expensive than those available in the market, but it "shouldn't be a hard pill to swallow, or a hard pizza to eat."
