Proving a point to her patients, Jennifer Lovdahl has had a Happy Meal sitting on her desk, uneaten, for years.
Now, Lovdah, who runs a chiropractic office in Anchorage, Alaska, wants the rest of the world to see what the still intact Happy Meal looks like after six years.
"It's been 6 years since I bought this "Happy Meal" at McDonald's. It's been sitting at our office this whole time and has not rotted, molded, or decomposed at all," Lovdah wrote.
"It smells only of cardboard. We did this experiment to show our patients how unhealthy this "food" is. Especially for our growing children!! There are so many chemicals in this food! Choose real food! Apples, bananas, carrots, celery....those are real fast food."
Since posting, the image has been shared over 200,000 times.
However, the frequently asked questions section on the Mcdonald's website says their food can rot.
"Food needs moisture in the air for mold to form. Without it, food will simply dry out – sort of like bread left out on a counter overnight to make croutons for stuffing.
"You might have seen experiments which seem to show no decomposition in our food. Most likely, this is because the food has dehydrated before any visible deterioration could occur."
While McDonald's is clearly an unhealthy option for children, sometimes it's the only option.
Mother of two, Paige-Alexis Cunningham, said in a Facebook post in January that she is tired of the "mum shaming" that goes with what foods she should and shouldn't be feeding her children.
"We're having watermelon for afternoon tea, Cunningham wrote. "For lunch we had McDonald's happy meals. For breakfast one kid had rice bubbles, the other refused to eat. At some stage they had some apple juice."
So why did she feed her kids a Happy Meal?
"Because they wanted it, we were out in public and I was bloody exhausted and didn't want to fight with them. They picked at it, and then demolished my sushi - which is terrible for kids by the way; the rice is full of sugar and the tuna is full of mercury!"
She added: "They also eat a tonne of those yoghurt pouches, but lately they've been added to the mum shaming list for having sugar in them. An apple has 23g of sugar, horrible hey! Wouldn't give that to my kids."
Instead, Cunningham believes parents should be proud they actually fed their kids today, because no matter what: a "a fed kid is best".
"Some weeks we purely eat cooked from scratch preservative free from the thermomix, but sometimes we eat junk.
"Feeding our children should be about education and moderation!
"Don't let them eat junk all the time, but don't lay the guilt on yourself or any other parent if they ate 2 minute noodles and Nutella today."
Cunningham finished her post writing, "At the end of the day there is no medal for Mother of the year. There is just this blessing and huge responsibility of being parents, which is left up to said parents to make the choices of how to raise their babies."
