6. Bad breath
Bad breath or halitosis is a common problem that affects a large part of the population. It can be a symptom of stomach complications or due to the presence of bacteria in the mouth. But it can also be caused by the lack of vitamin B6 and minerals like zinc or magnesium. We can improve this from the inside by eating fish, bananas, oysters and pumpkin seeds. Another tip? Coriander leaves and peppermint can also help.
