(TruthSeekerDaily) Once you watch this video you will never be able to forget it when you’re faced with the choice to consume a fast food burger

Chemistry professors from the University of Nottingham in the United Kingdom demonstrate how a McDonald’s cheeseburger breaks down during the digestion process, and the results are stomach-churning.

When you hear ‘hydrochloric acid’ you don’t think of something that’s found in your stomach. However, it’s there and occurs naturally, yet surprisingly has many industrial uses, from removing rust from steel to processing leather, according to the Huffington Post.

The video “A Cheeseburger in Hydrochloric Acid” shows University of Nottingham chemistry professor Martyn Poliakoff dunking half of the cheeseburger in a vat of hydrochloric acid, which gives the most realistic — and disgusting — visual representation of what really happens when we eat a burger.

“As you’re watching me, churning away in your stomach is acid which is one of the first stages in which food is broken down into usable components to give you energy or to make you fat,” Poliakoff says in the video. “Because hydrochloric acid is found in everybody’s stomach and it’s part of our digestive process.”

After three and a half hours, the container became bogged down with sledgy black murck from the burger, but did not completely break it down.
