Acne is often seen as a problem for teenagers, but adults are also troubled by it. In addition to genetics and lifestyle habits, diet plays an important role in the formation and aggravation of adult acne. Certain foods become the “behind-the-scenes pusher” of skin problems by stimulating inflammatory responses and hormone fluctuations in the body. This article will reveal seven types of foods that may aggravate adult acne to help you be more cautious in your dietary choices.
1. High-sugar and high-glycemic index foods
High-glycemic index foods such as white bread, white rice, candy, biscuits, and soda will quickly increase blood sugar levels, which in turn will cause inflammation and increased sebum secretion in the body. Excessive skin oil and clogged pores are the breeding ground for acne. Experts recommend reducing the intake of refined sugar and preferring natural fruits as a source of sweetness.
2. Dairy products: skim milk and whey protein
Skim milk is often observed to be associated with aggravated acne due to its high sugar and hormone content. Although whey protein supplements are favored by fitness enthusiasts, their stimulation of insulin-like growth factor 1 (IGF-1) will increase androgen levels, promote excessive proliferation of keratinocytes, and induce acne and inflammation.
3. Oat milk and soy protein
As a dairy substitute, oat milk may also worsen acne due to its high carbohydrate content. Although soy protein is a common protein source for vegetarians, excessive intake may also cause hormone fluctuations and induce skin problems.
4. Supplements rich in vitamins B6 and B12
Although vitamin B supplements are good for health, some studies have shown that B6 and B12 may change the skin microbiome, especially increase the activity of acne-related bacteria Propionibacterium acnes, thereby aggravating acne.
5. Iodine-rich foods and supplements
Although seaweed, kelp and other iodine-rich foods and related supplements are advertised as beneficial to skin health, excessive iodine intake can aggravate skin inflammation and oil secretion, becoming a hidden danger for acne to worsen.
6. High-fat and processed salad dressings (supplementary explanation)
Although this article focuses on acne-related foods, it is worth noting that high-fat, processed condiments containing additives may also indirectly affect skin health by promoting inflammatory responses.
7. Other foods that require caution
Any food that causes insulin fluctuations and inflammatory responses may be a trigger for acne. Maintaining a balanced and diverse diet and avoiding excessive intake of a single food is the key to preventing skin problems.
The formation of adult acne is the result of multiple factors, and diet is only one of them. As one writer said: “Healthy skin is the art of internal and external harmony.” Only by rationally choosing food, reducing the burden on the skin, and cooperating with good living habits can you usher in a clear and flawless face.
