Amazing daily developments inside you

The basic building blocks of our lives – the cells in the human body – are living organisms complete with their own organs and tissues … and their specific life spans. Each cell type lives a certain length of time and then dies.

We are constantly in a state of regeneration, endlessly making and re-making many of the smallest components of our bodies as they naturally come into being, flourish, and then wither.

Cells are where DNA is stored and protected from harm. Living and eating in ways that support this function of your cells means better health for you and your loved ones.

When cells are not healthy, the human body suffers.  Injured or damaged cells will die as a result of trauma or exposure to toxins or stress.

But whether injured or not, cells undergo a natural process called apoptosis that allows them to fragment and die, in effect “making room” for cell division, creating new organisms. So it’s important to understand that when new cells are created, whatever nutrients are currently available within the bloodstream are used as construction material. If the nutrients are rich, health is supported: if they are poor, health declines.

Although not all cells in the human body regenerate within a lifetime, the ones that do renew themselves provide a marvellous opportunity for us to guard against disease, live the most healthy and longest lives possible, and even heal injuries and illnesses.

Cell regeneration

Our bodies contain around 30 trillion cells, of which about two trillion regenerate each day. Different types of cells live and die according to different life spans.

When a person dies, some of their cells may live on for hours or even days – and this fact sometimes helps forensic detectives discern the cause and time of death in murder cases!

No one knows the exact origin of the myth about full cell regeneration happening every seven years, but that saying is highly misleading because cells are regenerating constantly.

Note, however, that while a great many human cell types regenerate, there are still some cells with life spans that match our own: meaning, the same cells we’re born with, in these instances, are still with us in their original form when we die.
