Especially carpets are now full of nasty stuff. We eat a lot of processed foods. The processing removes most of the vitamins, minerals and nutrients. The few things they ad back in 'fortified' foods, does not make up for the loss at all. Farmers use intensive growing methods that depletes the soil of minerals, so the produce is already low in minerals before any processing.
Much food is picked before it is ripe, so it ripes during shipment.
This again limits their vitamin and mineral contents. People of our age have more chemicals to break down in our bodies than ever before, at the same time, we eat food of a poorer quality than the previous generation. No wonder we have problems.
