Everyone keeps talking about detoxifying the body but what does that actually mean. If you stop eating toxins will start to build up in your body. The right way of getting rid of these toxins is to eat whole grain, unprocessed, fresh foods. Eat organic fruits, meats and vegetables and you'll be a lot better off than doing a rediculous detoxifying diet.
