Like the pH of your pee, the concentration of various compounds, and its levels of certain cells or molecules, such as nitrite.

The ammonia-laden water is therefore pumped through colonies of bacteria which, given enough oxygen, will convert the ammonia into nitrite and nitrate.

A diet high in sodium nitrites may also lead to a decrease in your body's ability to transport oxygen properly in your red blood cells.

高钠饮食也可能会降低你身体在红细胞中输送氧气能力。

During heat processing of the meat, a small portion of the additive sodium nitrite is suspected to turn into the cancerous nitrosamines like the earlier mentioned NDMA.

In fact, celery juice which has very high concentrations of nitrate, and is used to make the all natural “no added nitrates or nitrites” processed meat.

So, whether your bacon contains inorganic sodium nitrite or all natural nitrate from celery juice, it's not getting turned into the cancerous nitrosamines in your body.

But some bacteria produce enzymes that convert nitrate to nitrite, so extra nitrite in your pee is a sign of a bacterial infection, usually in the urinary tract.

但是一些细菌会产生将盐转化为盐酶，因此尿液中盐过多是细菌感染迹象， 通常是在泌尿道。
