The personal chef to 'power couple' supermodel Giesle Bündchen and Patriots superstar Tom Brady has spoken about the benefits of the couple's diet - revealing it is 'mainly plant-based'.
Chef Allen Campbell told Boston.com that '80 percent of what the couple eat is vegetables'.
He added: "[I buy] the freshest vegetables. If it's not organic, I don't use it. And whole grains: brown rice, quinoa, millet, beans."
Speaking about cooking for the couple, Allen said: "Around the time I met them, I had started really focusing on plant-based diets, because that’s where all the nutrition is.
"Their previous chef came from a very similar perspective, and they wanted something similar to their old chef.
"Even from the start, it was just such a great match between what they wanted and my philosophy."
Off the list
The chef also reveled what the couple doesn't eat. He said: "No white sugar. No white flour. No MSG.
"I'll use raw olive oil, but I never cook with olive oil. I only cook with coconut oil. I use Himalayan pink salt as the sodium. I never use iodized salt.
"What else? No coffee. No caffeine. No fungus. No dairy."
Bündchen and Brady do not follow a fully plant-based diet, as they eat some fish and animal products.
According to Allen: "I took a plant-based nutrition course earlier this year. It was an online course through Cornell, and it’s taught by a doctor named T. Colin Campbell, who’s behind The China Study."
"My philosophy is that a plant-based diet has the power to reverse and prevent disease."
Despite this, for Allen, a plant-based diet is 'based on whole foods', as opposed to being 100 percent plant foods. He admits this could mire strictly be referred to as a flexitarian diet.
He cooks some animal products for the couple, saying: "20 percent [of what they eat] is lean meats: grass-fed organic steak, duck every now and then, and chicken.
"As for fish, I mostly cook wild salmon."
He added: "Depending on the season, you bring in animal protein that are hopefully wild or organic and locally raised, but very small portions."
