If you feel like you’ve tried everything to clear up your acne, you may want to listen up. A new study has found that certain foods may contribute to an increase in breakouts and acne infections.

 Researchers at the University of California say they’ve found a direct link between foods such as meat, fish, eggs, dairy and salt-reduced Vegemite and increased acne breakouts in certain people.

The common denominator? All of these goods contain high levels of vitamin B12.

Apparently vitamin B12 alters the way acne-causing bacteria responds to a person's skin environment - particularly those who already have oily, acne-prone skin.

In the journal Science Translational Medicine, the study's authors say:

"Our findings suggest a new bacterial pathogenesis pathway in acne and provide more molecular explanation for the long-standing clinical observation that B12 supplementation leads to acne development in a subset of individuals". (Post continues after gallery.)

Before you go and throw away your beloved Vegemite (*wipes away tears*), remember it's a crucial element to healthy nutrition.

Vitamin B12 not only assists in brain function and nerve condition but also contributes to healthy blood production and functioning of the central nervous system. It also assists the human body in production of red blood cells.

In people who experience long-standing issues with acne, it may be worth discussing dietary options with your GP to determine whether a diet lower in Vitamin B12 would be of benefit to your individual situation.
