A woman has been storing McDonald's food in her cupboard for two years to prove that it "never goes off".
The nutritionist keeps a range of fast food - including pizzas, burgers and doughnuts - as part of an experiment to prove that food items don't go off.
A clip was shared on TikTok by the woman's daughter, with the caption: "Still fancy that burger?
"This is my mum's food cupboard - full of foods that never go off!
"My mum is a nutritionist, helping to tackle obesity.
"These foods shown here are ultra-processed foods that 80 percent of the UK consume on a regular basis."
The user, who posts on the social media platform as @elifgkandemir, explained that her mother is trying to encourage people to adopt a healthier diet.
She said: "No food is off-limits. My mum is simply trying to encourage people to make better food decisions and live a happier, healthier lifestyle."
