Both can cause headaches in some individuals. This is because these chemicals are naturally occuring in some parts of the body. Although many people do not have a problem with either of these, some will be sensitive.
The reasons aren't always known. Another common factor among those who suffer from recurring headaches can also be preservatives in foods or a number of things. I have suffered migraines since childhood, after trying just about everything on the market, my doctor suggested I keep a log of what I eat.
Problem solved, I have very few headaches. If you have persistent or chronic headaches, see your doctor. Make sure you rule out any possible health conditions and then look at your diet.
If necessary, keep a log of when you have headaches, what you are doing when they come on, what you have eaten, anything and everything. It may take awhile, but you can usually get to the bottom of it. Just make sure that this is not a health problem.
Good luck!
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
