Which one alter Immune system ?

A?

stress? when u're stressed, cortisol increases, causing it to suppress the immune system. also, access intake of steroids eventually causes one to be more prone to infection due to suppressed immune system.

C

C. Diet ....
hv a look at this site...

I would pick up A stress .. This is natural response from me.
Diet "C" ... It didn't specify the diet type or any other thing to say diet affect immunity although it seriously does under certain conditions.
So, I think "A" is correct as mentioned in the Pathophysiology of many diseases.

I have the impression that the question is a little too obvious. Isn't there any trick or something? Anyway I am comfortable with A-stress

yeah because if its diet then it wont be a direct immediate influence anyways. wont it take a while? whereas stress is immediate. just like u could never pee when u are stressed or angry. these are direct internal influences.

and i read the article by the cleveland clinic. yes diet does affect it but long term. its something we should practice all the time. and the article also mentions trying to relax a lot because stress influences immune system too. so the article linked really doesnt give a definite answer.

what is the answer by the way?

Choice D.

Psychoneuroimmunology. Studies in this area have demonstrated that many immune components can be altered by behavioral factors such as stress, depression, isolation, relaxation, and bereavement.

i go for A too

A. Stress i think
