" Myth #2: Acne is caused by diet. Extensive scientific studies have not found a connection between diet and acne. In other words, food does not cause acne. Not chocolate. Not french fries. Not pizza. Nonetheless, some people insist that certain foods affect their acne. In that case, avoid those foods. Besides, eating a balanced diet always makes sense. However, according to the scientific evidence, if acne is being treated properly, there's no need to worry about food affecting the acne."

"How many times have you heard it from dad and mom, friends or even the family health practitioner - a long list of foods that cause pimples. But after wide-ranging scientific studies, scientists have found that acne is not induced by eating food.

Extensive investigation has been made to verify whether or not foods cause acne, and while some studies may have suggested an correlation, there is no sign to support that acne is related to what you eat. In spite of what you have been advised, chocolate, sweets or pizza are not on the list of foods that cause acne!"

Question: Does Eating Chocolate Cause Acne?

Answer:

Good news for all you chocoholics: Eating chocolate does not cause pimples. Skin care experts agree that acne is not caused by any specific food, including French fries, candy, soda, or potato chips.

The real acne causes are a buildup of dead skin cells within the pore, an excess of skin oil (called sebum), and a proliferation of acne-causing bacteria. None of these factors are triggered by the foods we eat.

Probably the biggest myth of all is that eating greasy foods causes your skin to produce more oil. Greasy foods, while not really good for your health, will not cause oily skin or produce pimples. In fact, hormonal changes within the body have the greatest impact on sebum production. The predisposition toward oily skin can also be hereditary. So if your parents have oily skin, you probably will too."
