An F1 driver has to be fully on top of their health both physically and mentally which includes their diet.
As you can imagine, fruit is a vital component but Lando Norris' very specific choice left his McLaren team-mate Oscar Piastri visibly stunned.
The British ace, who has scored two podiums this season, revealed in a video on the team's YouTube channel that he only eats green bananas.
Piastri automatically assumed that Norris wasn't being totally truthful but the 23-year-old insisted he does, rather than eating fully-ripened yellow bananas.
"I don't know what other colours you can get, but I only eat green bananas," Norris said.
"No one eats brown bananas so I'll say it's a fact." Piastri then understandably asked. "Surely you don't eat green bananas, do you eat yellow bananas?"
"It's like a mix from green to yellow," came the answer. "Like a faded green because if it's fully yellow, it's already too late."
