Citric Acid


I remember that a few years ago, rumors had spread that citric acid is dangerous to health because it causes cancer.

After that, I and my friends carefully avoid the products containing citric acid. It was a real disgrace, almost every present product contains it.

After a while, I remember thinking about why citric acid is so dangerous and why I should avoid it.

After thorough digging on the Internet – to my surprise – I did not find a lot of certainty about the danger of citric acid, but information about how rumors of her dangers were wrong.

Many scientists, and alternative doctors agree that citric acid is one of the most dangerous additives (supplements) that have ever existed.


What is citric acid?


Versatile and widespread organic matter, citric acid is a colorless crystalline compound belonging to the family of carboxylic acids. Lemon acid is present in all plants and tissues of many animals. We find the highest concentration of citric acid in lemon and other citrus fruits.


First, citric acid was obtained from lemon juice. Swiss chemist Carl Wilhelm Scheele was the first citric who find acid in lemon juice in 1784 using the Aspergillus niger fungus.

In our time citric acid is mostly obtained by fermentation of cane sugar or molasses in the presence of Aspergillus niger and sometimes from lemon or pineapple.  So, citric acid is not a chemistry – as many think.

Citric acid is widely used in the food industry. You can find it in a whole range of products – in non-alcoholic beverages, juices, biscuits, cheese, sweets, cakes, biscuits, ice cream, jam, marmalades, pastries and sauces, cans, etc.


Which health problems can cause citric acid?


It is known that citric acid is a local irritant. This means that unrefined citric acid can irritate the skin. In addition, large amounts of citric acid can cause dental erosion. For the same reason, it is not recommended to take large amounts of lemon juice or other citrus fruits daily, containing large amounts of citric acid.


Does the citric acid cause cancer?


A rumor about the fact that citric acid causes cancer is wrong. The mistake was, allegedly, due to the surname of a scientist who discovered the cycle of citric acid – Adolf Krebs (Krebs in German means cancer).

Lemon acid (E330) is not carcinogenic. If citric acid would cause cancer, any cell in our body would turn into a cancer cell because citric acid is present in each of our cells, right next to DNA.

By contrast, citric acid is considered to be one of the safest additives in the food industry.

To make the story more fun, it has been discovered that citric acid has anti-cancer properties. It is even used in some alternative methods of treating cancer.
