Strong nervous system

For good memory and strong nervous system, consuming onions is your best bet. When we get quercetin by eating an onion rather than consuming the quercetin in purified, supplement form we may end up getting better protection from oxidative stress. Thats exactly what happened in an animal study where some animals had yellow onion added to their diet in a way that would provide the same amount of quercetin provided to other animals in the form of purified quercetin extracts.
