Our body is not designed to handle pesticides and other chemicals, but even then, it will do its best, and so for a long time, you may not suffer the effects. These chemicals will be stored in certain tissues, like the liver and may cause harm only when they reach a critical mass. Chemicals are carcinogens – they cause cancer. Chemicals are also hormone disruptors, and the cause of a whole range of hormonal problems – diabetes, hypothyroid, polycystic ovarian disease (PCOD or PCOS), premature puberty, infertility, breast, prostate and ovarian cancers, and more.
