The study, observed and followed through 94 high school students with mild to moderate acne for several months by researchers at Wake Forest . Acne is generally associated with high levels of sebum, the oily substance that coats the skin and protects the hair. Because sebum levels are known to wax and wane with variations in time, the study was conducted in Singapore where the temperature and humidity rarely change.

The findings revealed some periods of high emotional stress among students like the exams. As the students were preparing for the exam, 23 percent were more likely to suffer buttons. At the same time, their sebum production did not vary much whether they were experiencing high or low stress, indicating that levels of the substance have little or no role. Instead, the results may have more to do with inflammation. Other studies have proven that stress can cause inflammation and acne, of course, is an inflammatory disease.

The Australian Broadcasting Dr. Karl Kruszelnicki said that one of the reasons for chocolate-acne myth is the rumor link between high fat chocolate and fatty oil called sebum. Sebum blocks skin ducts and causes acne, or “zits”. However, in reality, oil has nothing to do with chocolate.

The real cause of acne is an accumulation of dead cells in the pores, excess skin oil (known as sebum) and a proliferation of acne bacteria. None of these factors are triggered by the food we consume.

However, If a food seems to cause more pimples for you, avoid eating that food. But remember, there was no direct link between a specific food to the establishment of the buttons. Go ahead and enjoy that piece of chocolate or order of chips (in moderation, of course). Your skin will be no worse for the next day.

It’s not the chocolate or french fries that you always worry about; consider your diet as a whole and avoid some foof that cause the zits.
