I believe I would say micro nutrients..........the CDC says “Micronutrients are dietary components, often referred to as vitamins and minerals, which although only required by the body in small amounts, are vital to development, disease prevention, and wellbeing. Micronutrients are not produced in the body and must be derived from the diet.”
Clostridium botulismis most frequently associated with foods that are canned at home and are either improperly prepared or are stored in poorly sealed containers.
I would say D. because exercise helps you sleep and concentrate, but it can also help fight depression. Trust me on the depression part ; ) Hope this helps!
