BPA spikes 1,200 percent after eating canned soup: study
People who ate canned soup for five days straight saw their urinary levels of the chemical bisphenol A spike 1,200 percent compared to those who ate fresh soup, US researchers said on Tuesday.
Urine is a liquid waste product of the body secreted by the kidneys by a process of filtration from blood called urination and excreted through the urethra. Cellular metabolism generates numerous waste compounds, many rich in nitrogen, that require elimination from the bloodstream. This waste is eventually expelled from the body in a process known as micturition, the primary method for excreting water-soluble chemicals from the body. These chemicals can be detected and analyzed by urinalysis. Amniotic fluid is closely related to urine, and can be analyzed by amniocentesis.
