DNA Damage and Ageing

DNA damage over a period of time is known to be the underlying cause of ageing.

What is the basis of ageing and age-related diseases? Various studies point to the accumulation of damage on the DNA, also called mutations, to be the causative factor.

This may be triggered by various agents, like oxidants, chemicals and radiations.

Every living cell harbors mitochondria, other wise known as the cell’s ‘power house’ that recruits oxygen to produce energy. The by-products of this process are the oxidants that damage the DNA and other cell components. However the cells are not without their own soldiers. The ‘surveillance’ genes are geared into action to defend the cells against the damaging oxidants and to repair the existing damage.

Dear Sir, For the ageing problem to be slow we require the basic natural necessities i.e., clean air, clean water and clean environment. None of the above is present now anywhere in the world except perhaps in Amazon forest and congo forest. There also human beings have gone and slowly spoiling it. So called scientists take quantity x from nature and give back only x-1,2... In Hindu philosophy it is called Yuga characteristics. Nothing can be done except crying from rooftops to stop pollution. IT IS A PITY. HS NARAYANAN

Dear Sir, Article is excellent. I will be very thankful. Food restriction is the process which most probably will limit the load of OXYRADICALS in the system thereby postponing the Age Related changes. Please send me the references so that the issue of FOOD RESTRICTION and how it works can be cleared. Thanks Dr. VENUGOPAL

I sometimes wonder what is the so called "good" or "bad" in terms of diet.The dietary recommendations keep changing on a day to day basis. I suppose the good old practice of our ancestors to eat timely meals prepared from chemical free ingredients should do the trick.
