The Road to Ammonia

Why do I smell like Ammonia? This question, in thousands of variations, has been asked over and over again at every major question/answer site, especially teen, bodybuilding and athletic forums.

The Internet provides plenty of opinions.

Medical sites talk about diseases like chronic kidney failure, hepatic cirrhosis or H. pylori infection. Fitness sites recommend drinking more water, reevaluating protein sources and eating more carbohydrates.
What are these diet-odor links? And what's the Science? Ammonia may be formed during the alkaline hydrolysis and deamidation of proteins - by our own metabolism and the metabolism of microbes that call us home. If our kidneys can't handle the load of nitrogen, it's excreted as ammonia in sweat. Excretion increases 10 times as temperature goes from 70 to 100 Fahrenheit.

Aurametrix is a breakthrough analysis tool that correlates users' actions and reactions based on what information they enter into the system. Preliminary correlations in the Aurametrix knowledge base show exactly what's expected: excess protein does lead to ammonia-like odor.

But wait a minute - does it say the same about excess fat?

An  example provided by one of our users is very interesting. The user logged a few foods he thought were contributing to odor. These were different odors according to the user - ranging from "Ammonia-like" to "Fishy", sharp, cloying and stale. Aurametrix, however, recognized that all these odors described by the user may be related to nitrogen-containing compounds.  When these three data points were analyzed along with four foods that the user did not associate with any odors, Aurametrix displayed only one result:

Based on your Aura entries, the following may be contributing to "Ammoniacal odor" in a 3 hour timeframe:

Hexadecanoic acid  - commonly known as Palmitic acid - is one of the most common saturated fatty acids in the Western diet. Palm oil and coconut oil contain especially high levels of this acid. What effect does this acid have on metabolism? It down-regulates glycose metabolism and protein metabolism, affecting Calcium or mRNA binding proteins [1]. So there may very well be a connection!
