What nutritionists say they’d never eat — and their favorite treats

Health nuts just wanna have fun — once in awhile.

News that an irate client fired her personal trainer after spotting the fitness fanatic eating a McDonald’s burger may have those who push good habits for a living looking over their shoulder when indulging.

However, according to nutrition experts, there’s nothing wrong with enjoying a favorite treat every once in awhile — it’s all about moderation.

A panel of nine nosh know-it-alls revealed to The Guardian exactly how they let their hair down when the time is right — and the hungry-making answers were somewhat surprising, ranging from comforting desserts to a favorite chocolate brand.

Equally revealing — a list of no-go goodies the sustenance specialists say they would never let pass their lips.

Each one of the interviewees had at least one banned item that rarely, if ever, makes it on to their prestigious plates.

Oysters, for example, were out of the question for Xuxa Milrose, in-house nutritionist at Omni Wellness.

“They commonly carry Vibrio vulnificus and Vibrio parahaemolyticus, which are types of bacteria that can cause abdominal cramping, nausea, diarrhoea, vomiting, chills and fever,” Milrose said.

The shellfish shaming comes as a foodfluencer in London recently made a splash on social media showing herself consuming a whopping 70 oysters for breakfast — apparently suffering none of the dreaded drawbacks.

Chocolate, however, Milrose was all in favor of.

“Chocolate has some credible benefits,” the sweets sneaker explained.

“The polyphenols in dark chocolate with a 70% or higher cocoa content help reduce inflammation and act as an antioxidant. They may even contribute to easing feelings of anxiety and improve symptoms associated with depression,” she continued.

Breakfast cereals, particularly sweet ones like Froot Loops, were a non-starter for another expert, while still another preached — rather predictably against fried foods.

One pro, however, couldn’t say enough about their dislike of something most people might associate with a healthy diet.

“I tend to steer clear of “low fat” products, ” said Sarah Berry, professor at King’s College London and chief scientist at Zoe.

“To remove fat from food that naturally contains it, such as milk or yogurt, it must be processed. This removes beneficial nutrients and adds unnecessary and potentially unhealthy compounds such as flavourings, emulsifiers and stabilisers. It’s better to enjoy the real thing in moderation,” Berry urged.

Berry confessed to enjoying the odd bacon sandwich on white bread with butter, a popular treat in Britain.

Other sneaky faves mentioned by the calorie-counting crew were a mug of hot chocolate, artisan baked goods, healthier homemade versions of favorite takeout meals and classic desserts like fruit crumble with ice cream.

“Even ‘unhealthy’ foods can have their place in a balanced life,” Berry stated.

“Food plays a powerful role in creating memories and joy.”
