Simulation shows what happens to body if you consume drink labelled by heart surgeon as 'liquid death'

Maybe when we start calling things a ‘fridge cigarette’ we should have probably known they might not be the best for our health.

But to be fair, ‘liquid death’ doesn’t quite have the same, fun ring to it.

That’s what heart surgeon Dr Jeremy London is referring to the drinks as though. And it’s not even about booze, rather the likes of soft drinks and fizzy drinks that he says he cuts out from his diet to protect his longevity.

The doc did list these (let’s face it, very popular refreshments) among the likes of alcohol, smoking, breads, pasta, refined flours and wheats as items he avoids at all costs for his health.

And while he admitted some of it was a bit of an attention tactic, a simulation shows just what the impact of drinking fizzy drinks is.

Shared on TikTok, the video shows what goes on inside the body when you consume a soft drink.

It explains that the drinks’ ‘carbonation and liquid form’ enables it to travel down ‘the oesophagus quickly’.

The fizzing bubbles are therefore apparently able to reach the stomach ‘within seconds’.

Here, the simulation says: “Phosphoric acid and caffeine stimulate extra gastric acid production while massive sugar causes a rapid insulin surge.

“The fizz can cause bloating or burping in some.”

The liquid is shown filling and fizzing inside the body as the narration continues: “Caffeine is absorbed fast through the stomach wall, entering the blood stream within minutes, while blood sugar rises sharply from all the high fructose corn syrup [that many fizzy drinks may contain].”

It then says that over in the small intestine, additional sugars and caffeine get absorbed into the bloodstream ‘fuelling a quick energy spike’.

However, it says it can also contribute to ‘potential crashes later’.

The simulation then shows the brain as the caffeine increases ‘alertness, focus and dopamine levels’.

“Caffeine triggers a short rise in heart rate and blood pressure,” it continues. “The carbonation and acidity may also contribute to reflux or discomfort for some.”

It's worth noting of course that while there can be the likes of additives, some soft drinks are caffeine free or sugar free.

In his video, Dr London branded soft drinks as ‘liquid death’ as he warned: “Just don’t drink them. Period. Done.”

And speaking to TODAY , he claimed that his extreme attack on fizzy drinks was an attention tactic.

"I think that soft drinks are just a scourge in our society, and so I was really trying to get some attention," he admitted.

"Obviously, high-calorie soft drinks and ingesting a lot of calories that people don't realise they're getting with the sugar-based soft drinks is a big no-no."
