It's called the "progressive modern" philosophy of eating and cooking, in other words for the average person, it's a strict plant-based diet which bans all dairy, white sugar, white flour, MSG, iodised salt, caffeine and even tomatoes, capsicums, mushrooms and eggplants.
"If it's not organic, I don't use it," Tom Brady and Gisele Bundchen's personal chef Allen Campbell tells boston.com.

For a couple who heavily rely on their bodies to make a living, it's no surprise that the pair follow a strict eating plan.
"Eighty per cent of what they eat is vegetables and whole grains: brown rice, quinoa, millet, beans," says the chef.
"The other 20 per cent is lean meats: grass-fed organic steak, duck every now and then, and chicken. As for fish, I mostly cook wild salmon."
Stating on his website that "nature has given us all we need to be at our best" and that we only require the raw and natural ingredients to survive, Campbell says that they all just clicked.
"It was just a great match between what they wanted and my philosophy," he says.
"They were just really laid-back – that's how they are."
As for the power couple's two children, there are no tantrums when they're served bowls of spinach and kale.
"Ninety per cent of the time they all eat the same thing," he says.
Having been the first person to give youngest daughter Vivian her first whole foods, Campbell is familiar with their favourites and makes them special treats – organic of course.
"For snacks, I make fruit rolls from bananas, pineapple, and spirulina," he says.
"Spirulina is an algae. It's a super fruit. I dehydrate it. I also make raw granola and raw chocolate chip cookies."
But the diet is more complex than just your basic 'clean eating' for the #12 Patriots quarterback.
"Tom doesn't eat nightshades, because they're anti-inflammatory," Campbell says.
"So no tomatoes, peppers, mushrooms, or eggplants. I'm very cautious about tomatoes. They cause inflammation."
The 38-year-old recently reported to WEEI that he felt betrayed by a lot of food and beverage companies over the years and how he likes to encourage his teammates to also change their eating habits.
"We believe that Frosted Flakes is a food," he said.
"You just keep eating those things, and you keep wondering why we have just incredible rates of diabetes in our country. Of course they taste very good – that's what we're brainwashed to believe, that all these things are just normal food groups."
Maintaining the families sugarless diet, Campbell confirms their day on a plate isn't what you typically see.
"It's very different than a traditional American diet," the chef says .
"But if you just eat sugar and carbs – which a lot of people do – your body is so acidic, and that causes disease. Sugar is the death of people."
Hoping to spread the message that good health can cure and more importantly prevent disease, Campbell continues to cook nutritious food for the couple.
"The job is so gratifying for me," he says.
"I think that's what makes me happy. I get to really do what I want, and they get to benefit."
