What does the human body consist of?

According to The National Center for Biotechnology Information (NCBI), approximately 1011 cells die in the body of each adult each day and the same amount is replaced by the new cells. As a matter of fact, the mass of cells we lose each year through the cell death process is close to our entire body weight. What does that information give us?

First principle

Our body has the definite composition

The human body and its cells has the definite composition. So to produce a new cell in place of a died one, our body has to have all the necessary materials for creation. What exactly do we need?

ELEMENT COMPOSITION OF THE HUMAN BODY

The mass of the body is composed of different chemical elements:

98.7% of them are the next six: oxygen (O), carbon (C), hydrogen (H), nitrogen (N), calcium (Ca), and phosphorus (P).

1.2% is made up of another five components: potassium (K), sulfur (S), sodium (Na), chlorine (Cl), and magnesium (Mg). These 11 are necessary for life. It is a scientifically proven fact.

The remaining 0.1% are trace elements. It is also proven that more than a dozen of them are necessary for human life too. Among them are boron (B), chromium (Cr), cobalt (Co), fluorine (F), iodine (I), copper (Cu), iron (Fe), manganese (Mn), molybdenum (Mo), zinc (Zn), selenium (Se), tin (Sn) and vanadium (V).

CHEMICAL COMPOSITION OF THE HUMAN BODY

The composition of our body also can be described in terms of chemicals as the set of:

water, proteins (present at connective tissue and hair and so on), fats, hydroxyapatite (present at teeth and bones), carbohydrates, DNA and RNA, dissolved inorganics such as sodium, potassium, chloride and phosphate, different gases, organics including amino acids and fatty acids, and vitamins.

Second principle

We are what we eat

All the elements from above are necessary for every day cell renewing. How do we get all these into our body? The source is only one – human nutrition. So literally, we are what we eat.

Third principle

A lack of elements provokes diseases.

To sum up, we need to obtain with our food everything our body needs for cell renewing. There are no other ways to have it only food. So if there is a lack of some elements in you daily diet, the body can’t have all the necessary blocks to produce cells in normal way. That’s why the body may become thick with time in different senses.

Amino Acids Definition

What are amino acids in simple terms? Amino acids definition is not complicated at their core. So, amino acids are proteins that were split into particles. Here are the list of amino acids and their roles on the human body.
