Frozen chicken - Less B vitamins

A study looked at fresh and frozen chickens. They had a "surprising result" with only 10% of vitamin B5 and only 25% B3 (niacin) and B9 (folic acid) of vitamins remaining. It was surprising as previous studies didn't show this. It is a reminder that we really don't know how to preserve the nutrients in food when we process them.
