Our bodies are amazing machines made to help us run on the food we eat and remove what we do not need. However, food is changing faster than we can evolve, and some of the things found in our food end up staying in our bodies and, sometimes, even in our fat cells.
Water soluble toxins are easily removed from the body via urine or sweat. However, fat soluble toxins are not so easy to remove, and the body ends up storing these toxins in the fat cells.
“The National Health Adipose Tissue Survey (NHATS) sampled fat cells in the US [starting in 1967 and concluding in late 1980s] and found over 20 toxic chemicals in a regionally diverse sample of the population. Since the green revolution and better living through chemicals in the 1940s many fat soluble chemicals have been introduced into the environment and thus the food chain. Many of these are foreign to the detoxification pathways of the body, and so the body is unsure how to respond and will store them in the fat cells. If the toxins are in the body for a short period of time then it is unlikely that they will do much harm, but when they are stored in the fat cells, their effect on the body is not positive. As they continue to accumulate, the oxidation and free radical damage that they cause can lead to metabolic and systemic dysfunctions.” (source)
