Publication Date: September 29, 2025

Update Date: January 15, 2026

Foods that cause acne can disrupt the oil balance of the skin, leading to clogged pores and the formation of inflamed acne. Especially fatty, sugary, and processed foods are among the primary nutrients that increase skin problems. Research shows that dairy products, junk food, and certain nuts are also among the foods that cause acne. Foods causing acne that are consumed regularly can also lay the groundwork for the formation of comedones and blackheads on the skin. Eating healthy and balanced is one of the most effective ways to reduce these negative effects.

List of Foods that Cause Acne the Most

Foods that cause acne the most are nutrients containing high fat, sugar, and additives. These types of foods can both disrupt hormone balance and increase acne formation by causing the skin to produce more sebum. Here is the prominent list of foods that cause acne:

Junk foods that cause acne: Chips, biscuits, chocolate, and candies negatively affect skin health.
Nuts that cause acne: Peanuts, cashews, and overly salted nuts can trigger acne formation in some people.
Meals that cause acne: Fatty and processed fast-food types such as pizza, hamburgers, and fried foods.
Foods and drinks that cause acne: Carbonated drinks, energy drinks, and excessively caffeinated products.
Milk and dairy products: In some individuals, yogurt, cheese, and milk can increase acne formation due to hormonal effects.

These types of things that cause acne can lead to clogged pores and the formation of comedones and blackheads when consumed regularly. For a healthier skin, it will be beneficial to reduce these foods or prefer their alternatives.

Sugary and Refined Carbohydrates

One of the most overlooked issues by individuals experiencing acne problems is the negative effects of foods containing sugary and refined carbohydrates on the skin. These foods with a high glycemic index rapidly raise blood sugar and cause fluctuations in insulin levels. This situation lays the groundwork for clogged pores and acne formation by increasing sebum production. Additionally, since refined carbohydrates increase inflammation in the body, they can cause existing acne to become more severe. Sugary and refined carbohydrates that may cause acne are as follows:

White bread
Sugary corn flakes
Pastry products (savory pastry, buns, cookies)
Packaged cakes and wafers
Sugary carbonated drinks
Sugary breakfast cereals
Ice cream
Ready-made fruit juices
Chips and salty crackers
Chocolate snacks

Milk and Dairy Products

Among the foods that cause acne, milk and dairy products also draw attention. In some individuals, foods such as milk, yogurt, and cheese can cause oiliness on the skin and acne formation by affecting hormone balance. Growth factors and hormones found in dairy products can increase acne problems, especially during the adolescence period. Milk and dairy products that may increase the risk of acne are as follows:

Milk
Yogurt
Cheddar/Kashar cheese
Feta cheese
Chocolate milk
Ice cream
Clotted cream
Cream

Fatty and Processed Foods

Fatty and processed foods can cause clogged pores by increasing the sebum production of the skin. Since these types of foods also contain trans fats and additives, they trigger inflammation in the body. When consumed regularly, they can increase the formation of both blackheads and inflamed acne on the skin. Fatty and processed foods that may cause acne are as follows:

Pizza
Hamburger
French fries
Crispy chicken products
Salami, sausage, and sucuk
Chips
Instant noodles
Snacks made with puff pastry

Nuts: Are They Always Innocent?

Although nuts are rich in terms of healthy fats and vitamins, some types can trigger acne formation when consumed in excess. Especially nuts with high oil ratios and salty nuts can increase acne problems by leading to excessive sebum production on the skin. Therefore, the consumption amount should be paid attention to. Nuts that have a risk of causing acne are as follows:

Peanuts
Cashews
Pistachios
Salty almonds
Roasted hazelnuts
Seed varieties
Overly roasted nuts

Junk Foods and Ready-Made Foods

Junk foods that cause acne negatively affect skin health due to the refined sugar, salt, and additives they contain. Ready-made foods, on the other hand, support acne formation with high calories and fat ratios that the body does not need. When consumed regularly, skin shining, enlargement of pores, and an increase in acne can be observed. Junk foods and ready-made foods that may cause acne are as follows:

Chips
Chocolate
Candies and jellybeans
Packaged biscuits
Ready-made cakes
Energy drinks
Carbonated drinks
Ready-made sandwiches
Packaged cookies
Fast-food chain products

Other Factors Causing Acne Formation on the Skin

Although foods that cause acne are one of the most important factors triggering skin problems, nutrition does not play the sole role in acne formation. Environmental and lifestyle factors also directly affect skin health.

Hormonal changes: The adolescence period, menstrual cycle, and increases in stress hormones can increase oil production on the skin.
Incorrect cosmetic products: Cosmetic ingredients that cause acne and makeup materials that clog pores can lead to acne formation.
Skin care mistakes: Washing the face frequently, using harsh cleansers, or sleeping without removing makeup weakens the skin barrier.
Stress and sleep irregularity: Insufficient sleep and intense stress lay the groundwork for inflammations on the skin by weakening the immune system.
Medication use: Side effects of some medications can embody ingredients that cause comedones and acne.

These factors can further intensify skin problems when combined with products that cause acne. For this reason, both nutrition and lifestyle habits should be reviewed together.

Foods Triggering Hormonal Imbalances

Hormonal fluctuations can increase acne formation, especially during adolescence, stress, and menstrual cycle periods in women. However, not only natural processes but also some consumed foods can trigger these hormone imbalances. High-sugary and processed foods cause fluctuations in insulin levels; meanwhile, dairy products and fast-food style foods also lay the groundwork for acne formation on the skin by disrupting the hormone balance of the body. Therefore, it is important to limit nutrients that affect hormones among foods that cause acne.

Foods that can trigger hormonal imbalance are as follows:

Milk and dairy products (milk, cheese, yogurt)
Desserts and candies containing high sugar
Carbonated drinks
Fast-food items (pizza, hamburgers, fried foods)
Refined carbohydrates (white bread, pasta, cakes)
Processed meat products (salami, sausage, sucuk)

These types of foods that cause acne can negatively affect not only skin health but also metabolic balance. Eating balanced and turning toward healthy alternatives support both hormone balance and skin health.

Excessive Caffeine and Energy Drinks

Coffee, tea, and energy drinks that are frequently consumed in daily life can negatively affect skin health when taken in large amounts. Excessively caffeinated products, which are among foods and drinks that cause acne, lead to a stress response in the body by increasing the cortisol hormone. This situation causes oil glands to produce more sebum and pores to clog. Especially high sugar and additives found in energy drinks can cause acne to become more dense and inflamed by increasing inflammation on the skin.

Caffeinated and energy drinks that may increase the risk of acne are as follows:

Excessively consumed coffee
Sugary instant coffee varieties
Energy drinks
Caffeinated carbonated drinks
Excessively consumed black tea
Sugar-added iced coffees

Although consuming a balanced amount of caffeine is not harmful, it can accelerate acne formation by disrupting both hormone balance and skin health when overdone.

Insufficient Water Consumption and Toxin Accumulation

Since a major part of the body consists of water, the role of water in skin health is quite large. When enough water is not drunk, the skin loses its moisture balance and toxin accumulation increases in the pores. This situation can further aggravate skin problems, especially when considered together with foods that cause acne. Water deficiency lays the groundwork for both acne and blackhead formation by slowing down the self-renewal process of the skin.

The results of insufficient water consumption and toxin accumulation are as follows:

Dryness and a dull appearance on the skin
Dirt and oil accumulation in pores
More dense acne problems with the effect of increasing foods that cause acne
Inflammation on the skin due to the body's inability to eliminate toxins
Weakening of the skin barrier and predisposition to irritation

Regular water consumption helps the skin purify from toxins, while at the same time creating a stronger skin barrier against things that cause acne.

Nutrition Recommendations for Acne-Prone Skin

Turning toward healthier nutrients instead of foods that cause acne is one of the most effective ways to alleviate skin problems. Individuals who have an acne-prone skin structure should focus on foods with high antioxidant, fiber, and water content in their daily diets. In this way, both the excretion of toxins becomes easier and the skin barrier is strengthened.

Nutrition recommendations for acne-prone skin are as follows:

Consuming plenty of fresh vegetables and fruits (especially green leafy vegetables, carrots, broccoli).
Consuming fish rich in omega-3 fatty acids (salmon, sardines, mackerel).
Preferring whole grains instead of refined carbohydrates.
Limiting milk and dairy products, trying plant-based alternatives.
Preferring plenty of water and herbal teas instead of sugary drinks.
Using a probiotic and postbiotic supplement to support gut health.
Supporting the balance with a magnesium supplement to meet the mineral need of the body.

A balanced dietary routine helps reduce skin problems triggered by foods that cause acne, while at the same time contributing to a healthier and more radiant skin appearance in the long term.

Turning Toward Anti-Inflammatory Foods

One of the most important reasons for acne formation on the skin is the rise of the inflammation level in the body. Especially fatty, sugary, and processed foods that take place among foods that cause acne can aggravate acne problems by increasing inflammation. Instead, turning toward anti-inflammatory foods supports both skin health and general immunity. These types of foods contribute to keeping pores clean and reducing inflamed acne by providing protection against free radicals.

Foods showing anti-inflammatory characteristics are as follows:

Fish rich in omega-3 fatty acids (salmon, sardines, mackerel)
Olive oil
Nuts containing healthy oils such as walnuts and almonds
Spices such as turmeric and ginger
Green leafy vegetables (spinach, arugula, chard)
Fruits rich in terms of antioxidants such as blueberries, blackberries, and strawberries
Vegetables containing lycopene and beta-carotene such as tomatoes and carrots

Consuming these foods regularly helps balance the inflammation triggered by foods that cause acne and ensures that the skin looks healthier.

Probiotic and Prebiotic Supported Foods

Gut health plays a critical role in the prevention of skin problems. A healthy intestinal flora helps toxins be eliminated from the body and strengthens the immune system. For this reason, probiotic and prebiotic supported foods are highly important in terms of providing balance in acne-prone skins. While probiotics increase beneficial bacteria in the intestines, prebiotics ensure the nourishment of these bacteria.

Foods rich in probiotic and prebiotic aspects are as follows:

Yogurt
Kefir
Pickles
Home-made vinegar
Fibrous vegetables (onions, garlic, leeks)
Fruits with prebiotic effects such as bananas and apples

To support gut health more strongly, the use of a postbiotic supplement can also be beneficial. These supports contribute indirectly to the cleaner and healthier appearance of the skin while regulating the digestive system.

Vitamins and Minerals Supporting the Skin

Adequate vitamin and mineral intake bears great importance for protecting skin health and reducing acne formation. Especially vitamins A, C, D, and E, and minerals such as zinc and selenium support the renewal process of the skin and strengthen the immune system. Regular vitamin intake provides a cleaner and more vibrant appearance by reducing the damage that free radicals create on the skin.

The primary vitamins and minerals supporting skin health are as follows:

Vitamin A (carrots, sweet potatoes, spinach)
Vitamin C (oranges, kiwi, red peppers)
Vitamin E (almonds, hazelnuts, avocados)
Vitamin D (sunlight, fatty fish)
Zinc (pumpkin seeds, lentils, red meat)
Selenium (eggs, walnuts, whole grains)

It may not always be possible to take adequate amounts of vitamins with daily nutrition. At this point, the use of a multivitamin supplement can contribute to the protection of skin health by helping eliminate deficiencies.
