C: Humans share about 50% of their DNA with bananas.

Your DNA is about:

  • 99.5% the same as any other human
  • 97% the same as a chimpanzee
  • 90% the same as a cat (our common ancestor lived about 90 million years ago)

Other approximate comparisons:

  • 82% DNA similarity to dogs
  • 80% to cows
  • 69% with rats (although some humans seem even more similar!)
  • 67% with mice
  • 60% with a fruit fly (Drosophila)
  • 60% with a chicken

Your DNA is vulnerable to excess free radical damage (oxidation) which accumulates with age. Free radical damage occurs during normal metabolic processes, but is made worse by long term inflammation accumulating in tissues as we age and by exposure to cigarette smoke, city pollution and industrial chemicals.

Damaged DNA leads to cells dividing out of control – the start point of cancer.  A range of anti-oxidants in your diet can limit this damage. Fruits and vegetables, Omega 3 oils and the spice-derived curcumin are important sources of anti-oxidants.

If you are ever tempted to say “I don’t feel human today” – you are right. Some 50% of the cells that make humans aren’t “human” in origin. They mostly originated from viruses, fungi and bacteria. Indeed it is bacteria in the stomach and gut that produce the chemicals that enable us to harness energy and nutrients from our food.
