Jonathan Firestone Men’s HealthDr. Sowulewski4/11/18When it comes to health and the factors the affect ones health, it really boils down to how the body reacts with its internal and external environment. The internal environment being anything that naturally occurs or is supposed to occur inside the body (genetics, organ function, cell replication, etc.) and the external environment being anything outside the body that influences behaviors from the body (quality of breathable air, types of food put into the body, exposure to UV rays, etc.). While the internal environment is mostly out of your control, besides taking medication or seeing professionals about medical conditions, the external environment has a significant impact on how the body will act and can even alter theinternal environment. Japanese men are known to be some of the healthiest in the world and that is mostly due to their diet. Their diet consists of a healthy balance grains, fish, vegetables, fruits, some red meat and dairy products. However, they will also enjoy some snacks and alcohol, with moderation of course (Time Magazine).
