The human body needs more than calories. To live a healthy and long life, it is essential to be well
nourished, which means to get all the essential nourishment in the right ratio. WHO (World Health
Organization) recommends at least 55 %
carbohydrates,

in the adult human daily diet.
Carbohydrates are digested to glucose molecules in the human gut. From here they get into the blood
system, and are transported all around the body. Muscles use glucose as an energy source, by degrading it
through heat producing processes. Remaining amounts of glucose are stored as glycogen in the liver or as
fatty acids in adipose tissue, which allow us to maintain the blood sugar level during starvation.
Proteins are made of amino acids that act as the major building blocks for all enzymes and proteins in the
human body. Furthermore proteins are a structural component of bones, muscles, and the immune system.
There are 20 common amino acids, from which 10 are essential, which means that the human body is
unable to synthesize them, and we need to get them through the diet.
Fats are built up by long carbon chains, and function as an energy source. Fats can be stored in the adipose
tissue, where it insulates the body and protects organs against pressure and stress. Additionally, some
fats are of vitally importance, as they are involved in the uptake of fat-soluble essential
vitamins.

Too much or too little of one of the three food sources mentioned above can lead to change in weight,
weakness, health problems, disease, and undernourishment. Children can even be stunted or
wasted.

The optimal quantity of fat- and protein nutrients, could potentially be provided by Edible coli, since
it contains essential fatty acids and a nutritional protein, the OneProt, that includes the recommended ratio of
essential amino acids (recommended by the World Health Organization,
WHO).
