Welcome to the forum, Deepal.
Coming to,whether Black olives are not good for a woman's health:
There are no scientifically proven facts supporting the above said claim.
You should answer these questions first: Do you eat canned olives ?
Do you often eat olives stored in brine (salt water) or in the form of pickles?
If you're eating any of them in 'excess' then its bad because all the above contain MSGs (mono sodium glutamate) which is a food additive and a flavor enhancer. Over-consumption of this leads to hyper-tension,dizziness.
Even sodium taken in high amounts has a number of side effects.
Olives cannot be consumed as it is, it has to be fermented and black olives are a result of an olive ripening and originally not found in that color.
Canned olives have different chemicals that make an olive 'black' artificially so canned olives are not recommended always.
But there are no known 'women' related ailments in olive.
Hope this helps.
