Aging: whose fault is it?
Today we know that oxidative stress is involved both in the aging process of the organism and in the decline and worsening of cognitive functions, considered a chemical condition that is harmful not only to the health of the brain and nervous system, but also to the general well being.
What is oxidative stress?
It is the set of alterations and damage that occur in cells and organs due to free radicals, highly reactive and chemically unstable molecules which, under certain conditions, can be produced in excess and cause oxidative stress.
Among the main factors that favor the development of oxidative stress are aging, pollution and
What are antioxidants and why are they important?
In our cells there are systems, represented by particular substances so-called "antioxidant", which eliminate free radicals and usually keep oxidative stress at low levels. However, under certain conditions, the balance between free radicals and antioxidant systems can be disrupted. Brain, an organ that requires high amounts of oxygen, is very sensitive to oxidative stress and the antioxidant systems present in the nerve cells that constitute it are quite weak.
