US President Donald Trump has repeated claims he is a stable genius and insists he eats good quality food.
When asked by Britain's ITV about his health, and accusations he is mentally and physically incapable of being the leader of the free world, Mr Trump said: "I am a stable genius."
Among many allegations contained in the incendiary insider account Fire and Fury: Inside the Trump White House, author Michael Wolff attests that Mr Trump often retreats to bed with a cheeseburger at 6pm to watch television.
The book also claims Mr Trump is barely literate and openly scorned by key members of the administration.
The President has commonly fuelled concern over his eating habits, by posting photos of him tucking into takeaways to his 47 million Twitter followers.
When asked about his seemingly dubious diet, Mr Trump said: "I eat fine food, really from some of the finest chefs in the world, I eat healthy food.
"I also have some of that food on occasion... I think I eat actually quite well."
Mr Trump's diet has raised eyebrows for some time, with Mr Trump's own former campaign manager sharing the details of his diet, while on the campaign trail, as part of an upcoming book:
"On Trump Force One, there were four major food groups - McDonald's, Kentucky Fried Chicken, pizza, and Diet Coke."
Despite this, the White House doctor recently declared Mr Trump's health to be "excellent" and told reporters: "He might live to be 200 years old."
