Acne is a common skin disease, which is more common in facial, back and chest.There are many types of acne. It mainly focuses on polymorphic lesions such as acne, pimples, pustules, and nodules.Although acne is commonly known as "acne, many people will still" acne "in adolescence. Therefore, acne has no age limit.

Some opinions believe that some types of foods will aggravate acne, such as chocolate, cola, milk, etc.So the question is, is acne relationship with diet?

In the dermatology industry, the previous general views believed that the diet was not related to the cause of acne, because in the past 30 years, there were almost no objective data to support this view.However, more and more evidence now shows that the diet may directly or indirectly affect acne through the following 5 factors:

1. Internal keratin of the sebaceous gonad tube of the hair follicles form a cell proliferation increase;

2. The cottage of the catheter forming cells is incompletely separated from each other, resulting in the damage to apoptosis and the obstruction of the sebaceous gland gland gland duct;

3. Increased sebum secretion ofrogen -mediated male hormones;

4. Acnecelasacheramium is planted in the sebaceous gonad tube of the hair follicles;

5. Inflammation response in and nearby of the hair follicle sebaceous gonad tube.

Recently, a review article published in "Internal Journal of Dermatology" reviewed the literature on the relationship between diet and acne in the past 11 years. It also emphasized that the interest in the field of skin science has exponentially increased the growth of this subject.the trend of.

The review evaluated 42 observation research and 11 intervention clinical trials.The author found that a variety of dietary factors are related to acne.Among them, hyperglycemia generation index (GI) and high blood sugar load (GL) food, dairy products, fat foods and chocolate is a dietary factors that promote acne development.

The blood glucose generation index (GI) refers to the relative speed of blood glucose to increase the blood sugar within two hours of entering the human body.The food with GI is greater than 70 is high GI food.

Blood glucose load (GL) is an indicator of the quality (GI value) and quantity (gram per port) of carbohydrates in food, which illustrates the effects of blood glucose in the total amount of sugar intake on blood sugar.High -blood sugar load foods include sugary foods and beverages, white bread and rice.

In general, the conclusion of this summary is that there is a connection between acne and diet, but intervention research is weak than the foundation of observation research.

Researchers said that nutritional research relies to a large extent on the dietary memories of participants, so there are limited, prejudice and mixed variables.Because people often report to the ‘bad’ food, report more ‘good’ food, and the reported ingredients and portions are not accurate.

Professor Gabriella Fabbrocini, the University of Naulus University in Italy, supports the point of worsening acne in supporting the diet.Skin -milk) is the main factor that causes connection between diet and acne. "

This is because high blood sugar load (GL) diet and some dairy products will increase high insulin ledmia, which will cause endocrine reactions and stimulate insulin-like growth factor 1 (IGF-1) level.IGF-1 is a medium for cell growth, including the growth of hair follicles, and enhanced the biological utilization rate of androgen, thereby stimulating the production and secretion of sebum.All these impacts are recognized as factor in the pathogenesis of acne.Milk contains hormones that stimulate growth, including IGF-1, which are still high in their concentration even through Basus.Especially compared with high -fat milk, this connection among skim milk is stronger.The diet of low blood sugar load can improve insulin sensitivity, reduce the level of cyclingrogests, and then inhibit the development of acne.

Dr. Delost added: "In fact, according to our experience, patients with hypoglycemia load diet strategies will reduce total inflammatory acne disease. Most modern evidence shows that acne is also correlated with less intake of vegetables."

Dr. Jerry Tan, a dermatologist at the University of Ohio University, also agreed to dietary factors that cause acne to deteriorate. He said: "Hyperglycemia generation index (GI) food will increase the level of insulin and IGF-1. These two hormones can increase sebum secretionAnd make the sebum composition more conducive to inflammation. "

However, Dr. Kelly Haas, a skin microbiologist at the University of California, said: "There are many factors in pathophysiology of acne, and most of them are still unknown. Therefore, changing the diet strategy may not apply to all patients."

It is known that acne is related to hormone levels, and hormone levels will change during adolescence, menstrual cycle and pregnancy.It is also affected by genetic factors and reactions to drugs or cosmetics.

In short: Although more research is needed, the diet may really be related to acne.When you are in acne, you may wish to change your diet strategy, which may really alleviate this annoying skin disease.
