We are all surrounded by chemicals. Our soap, shampoo, perfume, deodorants, house cleaning supplies, dish washer soap, laundry soap, sometimes water that we drink, air that we breathe, the food that we eat (grown with pesticides/ fertilizers), clothes that we wear (processed with chemicals and dyes), everything is loaded with chemicals and toxins. To add to that we, with our own 'conscious will' decide to indulge in some more toxins like alcohol, drugs, cocktails, chocolates-deserts-ice-creams made with liquid nitrogen, preserved foods.
Humans have these empty voids that they try to fill up with some crazy entertainment (which is mostly consumption - as mentioned above). We have moved away from natural living big time.
We need to eat clean, simple food, explore variety but keep it simple, respect food. Food gives us energy, it was us, it is us, it repairs us, we are what we eat/drink and what we digest, food is sacred.
There is nothing safe in consuming alcohol, drugs or food loaded with chemicals (molecular gastronomy!), even though the argument will be, it is safe in small quantities. We are surrounded by toxins already, we don't need to add more to our body.
Change is required in the way we eat, move, sleep and think...
