The role of the liver is to break down everything that we ingest and the role of the kidney is to excrete it. Therefore, when we take in harmful ingredients through our non-organic or animal or packaged or fatty or fast foods we are putting a load on our livers and kidneys. Even alcohol can cause fatty liver. Jaundice can also have a detrimental effect on the liver. All these will show up as high SGOT and SGPT.
So, if you switch to a whole food plant-based diet of organic foods, and reduce the chemicals in your environment, the SGOT and SGPT will definitely reduce.
