Role in Human Health

Oxygen

The oxygen concentration in a healthy human body is approximately three times that of air. 80% of all our metabolic energy production is created by oxygen. The human body is largely composed of oxygen.

Eating junk food on a regular basis forces the body to use up more of its oxygen reserves than usual in order to metabolize the preservatives and what few nutrients may actually be in the “food”. Complex carbohydrates and raw fruits and vegetables are high in oxygen with as much as 50% of the weight of these foods made up of oxygen. The percentage of oxygen in fats is less than 15% while the percentage of oxygen in protein is between 20% and 40%, depending on the protein’s amino acid profile. Oxygen is the most abundant element on earth comprising nearly 50% of the earth’s crust and averaging about 20% of dry air in a non-polluted environment.
