It is mainly used to eliminated the odor resulted from ammonia, Trimethylamine gas alkaline.
When we eat foods higher in choline(like eggs, beef, and dairy),
the bacteria in the gut metabolize this and turn it into something called TMAO, or Trimethylamine N-oxide.
Then, to eliminate poisons, such as Trimethylamine oxide and uric acid(a compound found in urine), a shallow hole
is dug in the sand and the hákarl is placed in it with stones, sand, and gravel placed on top.
When you eat eggs, red meat, or dairy, bacteria in your intestine convert the choline in those foods- a helpful nutrient similar
to B vitamins- to a compound called Trimethylamine N-oxide, or TMAO, according to a
study released last year from the Cleveland Clinic.
Elevated levels of a molecule in the blood called Trimethylamine N-oxide, which is produced when your gut metabolizes red meat,
dairy, and eggs, predicted major heart events both 30 days after entering the hospital and up to 7 years later, according to the Swiss study.
