Why Can't Humans Produce Vitamin C?

David Brownstein, M.D. By Thursday, 16 April 2020 02:50 PM EDT Current | Bio | Archive

The human body has a remarkable ability to regenerate injured and old tissue. However, this regeneration process requires an adequate level of vitamin C.

Why humans do not have the enzyme needed to produce vitamin C has perplexed researchers since that enzyme was discovered.

Many researchers contend that our prehistoric ancestors did have the gene that enabled the body to produce its own vitamin C. But at some point in the evolutionary process, that gene became disabled and we lost that ability.

My theory is that humans evolved away from the enzyme because we were only eating food that we could either kill or gather. That meant humans ate copious amounts of fruits and vegetables, which supplied an adequate amount of vitamin C.

There was no such thing as refined food back then, and the human body did not have to waste precious resources producing a substance (vitamin C) that it was getting in abundance through diet.

Therefore, the gene responsible for manufacturing vitamin C was naturally altered.

Today, most Americans don’t eat enough fruits and vegetables, but do eat a lot of refined foods that have had most of their nutrients, including vitamin C, removed.

Eating a diet of refined salt, flour, sugar, and oils is guaranteed to lead to nutritional deficits.
