Human aging is a biological process, no one can stop, but delay it. It is possible that one person has a physiological younger than his or her biological if one engages in healthy living life style and eating healthily by increasing the intake of good healthy food such as whole grain, fruits, vegetables, beans and legumes, etc. and reducing the consumption of harmful foods, such as saturated fat, trans fat, artificial ingredients, etc.
                      
              
                                         The immune system

An immune system is a system of biological structures and processes within an organism that protects against disease by identifying and killing pathogens, including bacteria, virus, parasites, etc. and tumor cells, including irregular cells growth, cancer cells to keep us healthy. In most cases, the immune system does a great job of keeping people healthy and preventing infections. But sometimes problems with the immune system can lead to illness and infection.


            How free radicals affect Immune system

There are many factors which affect immune system as we age. Hormone declining such as human growth hormone and Dehydroepiandrosterone (DHEA) are the major influences. In factor, some researchers suggested free radicals is one of major contribution to the declining of immune system.
a. Thymus
The declining of the thymus function contributes a direct effect on the immune system due to diminish of quantity of T cells and immune factors.

b. Lipid peroxidation
Researchers found that lipid peroxidation are able to attack immune cells membrane, leading to the impediment of cells membrane activities, causing susceptibility diseases found in aging person.

c. NADHP oxidase
NADHP oxidase (nicotinamide adenine dinucleotide phosphate-oxidase) is a membrane-bound enzyme complex found in the plasma membrane. Free radicals cause damage to membrane, leading to diminish of its function in fighting against foreign invasion.

d. Cytokine
Free radicals damage immune cells that affect the function of cytokines in transmitting intercellular signals, leading to many disease states and conditions ranging from major depression and Alzheimer's disease to cancer.

e. Etc.
