A little bit of poison is good.”That poison can actually come from plants，especially those that have survived harsh conditions. Foods that have survived harsh conditions make us stronger by stressing our bodies，not because they’re rich in antioxidants.As the science quarterly Nautilus explains，plants have developed an arsenal of chemicals to help them ward off insects and grazers.
