In the world we live in today, we are surrounded by toxins and depending on where we live, some people have far more exposure than others. I'm a huge proponent of making sure to regularly detox the body. Essential oils seem to be the easiest and most convenient component to add to your daily routine to help aid your body in it's own detoxification process.
There is of course another easy, yet reluctant (for most) way to limit your toxic exposure, and that's through the food you eat.
In the mammal body, the liver is the main organ that deals with the toxins. Toxins are also stored in fat cells. This is why someone with a high toxic load will have a much harder time losing unwanted fat stores. The key is to dramatically reducing the toxic load in your diet is to eliminate eating animal products.
Let's take a cow for example. Even if it's grass fed (supposedly organic), it is still exposed to lots of toxins in it's own environment and food. When that cow is consumed, the consumer get's a more concentrated form of those toxins. Another example is in your Omega fatty acid supplementations. Fish are known for their bodies ability to highly concentrate toxins, and some fish more than others. Steer clear of any animal based Omega Fatty Acid supplement. A plant based Omega is just as good and without the concentrated toxins.
