E330 - citric acid is fundamental to the Cancer
Приветствие всем!
http://www.sciencenet.org.uk/database/Biology/0010/b00783d.html
E330 is citric acid (2 hydroxypropane 1,2,3-tricarboxylic acid) which is used for flavouring effervescent drinks. It occurs naturally in many fruits, especially lemons, but is now prepared commercially by fermentation by Aspergillus (a fungus).

Recorded problems are that it can be a local irritant and in large amounts can cause teeth erosion.
However there have been erroneous reports, caused by different languages, that it is a major cause of cancer. This has been brought about by misunderstanding and confusion over the word Krebs.
Citric acid is one of a series of compounds involved in the physiological oxidation of fats, proteins, and carbohydrates to carbon dioxide and water.
This series of chemical reactions, which is central to nearly all metabolic reactions and the source of two-thirds of the food-derived energy in higher organisms was discovered by the German-born British biochemist Sir Hans Adolf Krebs. He actually received the 1953 Nobel Prize for Physiology or Medicine for the discovery, and as well as being known as the tricarboxylic acid cycle (its correct name), it is also known as the citric acid cycle or the Krebs cycle.
Hence, citric acid is fundamental to the Krebs cycle and Krebs is the German word for cancer!
