I’m a sport’s nutritionist – here’s nine health tips Ronaldo, Messi, Harry Kane and Raheem Sterling swear by

THE 2022 Fifa World Cup has kicked off, and it’s been reported the England squad has packed huge quantities of protein-rich baked beans and Jaffa Cakes as sweet treats to help them feel more at home in Qatar.

England might have beaten Iran 6-2 yesterday, but South Korea has won in the health stakes, taking a whopping 200kg of gut-beneficial kimchi – aka fermented cabbage – to the tournament.

Beyond tonnes of kimchi, footballers have private chefs, personal trainers and nutritionists to keep them in tip-top condition, but don’t let that put you off picking up tips from the pros.

While we can’t guarantee you a World Cup debut as spectacular as Jude Bellingham’s, try these tricks for a serious health boost . . . 

HEART TO HEART: Man City ace Erling Haaland might not be at the World Cup (his home nation Norway failed to qualify) but his Hannibal Lector-style diet is helping him storm to Premier League success.

In his documentary Haaland: The Big Decision, he said: “People say meat is bad for you, but which? The meat you get at McDonald’s? Or the local cow eating grass right over there? I eat the heart and the liver.”

Which might explain why his fitness is so good, with both giving the cardio-vascular system a shot of health.

Jess Hilliard, nutritionist at Warrior (), said: “Eating liver can help lower bad cholesterol and raise good cholesterol – which can help ward off stroke.

“The nutrients contained in the heart support the function of the heart as well as the entire cardiovascular system.”

HOLE IN ONE: Get into the swing with a spot of golf.

Wales captain Gareth Bale and England skipper Harry Kane are both fans and Kane says it’s great for his mental health.

The Spurs star told Life Beyond Sport magazine: “It gets me away from football for a while and clears my mind.”

It can do wonders for your body too.

Jess said: “Golf can help you stay fit, while improving muscle tone and increasing endurance. It can also help you control body weight and reduce fat.”

BACK TO THE FUTURE: Footballers are all about marginal gains and right-back Trent Alexander-Arnold has worked on his peripheral vision and depth perception using visual training and augmented reality with Red Bull.

Basically, it means using hi-tech computer games to boost reaction times, memory and alertness – which is a great excuse for playing more virtual tennis on your Wii or racing round a track on your XBox.

CHECK MATE: Alexander-Arnold also plays chess, which he says gives him an edge on the pitch.

He told inews: “It’s similar to football, all about strategy and tactics and different ways of playing. I can see similarities in both games and use each game in the other as well.

“I try to use tactics from football on the chessboard.”

Your brain can particularly benefit from a tense game of chess.

Jess said: “Chess has been shown to enhance problem-solving skills and teach the value of patience. It can also help you cope better with stress and exercise the brain, heightening learning ability.”

SEA IT THROUGH: Believe it or not, Argentina’s Lionel Messi and Portugal’s Cristiano Ronaldo are both fans of seaweed, which is high in protein – vital to rebuild muscles after exercise – and also mineral-rich, which can help support libido and sexual function.

Jess said: “Seaweed is a great source of vitamins and minerals and contains a variety of protective antioxidants.

“It is also high in iodine, which helps with thyroid hormones to regulate metabolism.”

A regulated metabolism can help you stick to a healthy weight too.

NAP TIME: You’d think footballers were training constantly, but according to defender Eric Dier, it’s the downtime that makes all the difference – especially naps.

He told : “I love a nap, every day. I get eight or nine hours sleep at night and nap for 45 minutes in the afternoon, straight after training. It makes me feel better for the rest of the day.”

You might feel a bit groggy waking up from a quick kip, but Jess confirms the odd power nap can give you a lift.

She said: “Taking a nap has been shown to improve alertness and performance while boosting memory.”

ICE ICE BABY: Yes, they’re chilly, but many footballers and coaches swear by ice baths – Harry Kane, winger Raheem Sterling and defensive midfielder Declan Rice included.

In fact, Rice has said he prefers them to specialised cryotherapy chambers, which is good news for us, as a bath filled with a few bags of ice is much cheaper to recreate.

Rice told GQ: “I feel fresher after an ice bath so I usually choose that.”

And science backs up the deep freeze.

Jess said: “Ice baths ease aching muscles, help stimulate your central nervous system and limit the body’s inflammatory response (which can reduce pain, swelling and support injury recovery).”

GO FISH: Footballers need to make time for recovery too, and midfielder Phil Foden likes to spend his time away from the pitch fishing.
