Acne Lesson 4: The Clear Skin Diet

You’ve probably heard it before: “Chocolate causes acne.”


The truth? Chocolate itself isn’t the problem.


In moderation, high-quality dark chocolate is actually rich in antioxidants that support skin health. What can contribute to breakouts are the dairy, sugar, iodized salt, and additives often found in many chocolate products.


So what about fried foods, pizza, cheeseburgers, and milkshakes?
Those are far more likely to trigger inflammation and acne.


The good news? There are foods that actively support clear skin—and understanding the why behind food choices can make your acne journey feel far more manageable.

Does Food Really Cause Acne?

What you eat plays a significant role in your skin’s health.


Your skin is your body’s largest organ. It protects you, regulates temperature, and allows you to experience the world through touch. It’s also the face you present to the world—and when it’s inflamed or breaking out, confidence often takes a hit.


Even though food doesn’t go directly on your skin, what you eat influences:

  • Inflammation levels

  • Hormone balance

  • Sebum (oil) production

  • Gut health

  • Allergic or sensitivity responses


Certain foods can fuel acne, while others help calm inflammation, support healing, and improve skin clarity over time.


Clear skin isn’t about perfection—it’s about making informed, consistent choices.

Nutritional Support for Optimal Skin Health

The right foods can:

  • Reduce inflammation

  • Support hormone balance

  • Protect against oxidative stress (premature aging)

  • Help you clear acne faster


A low-glycemic, whole-food-based diet supports not only clearer skin, but better overall health.

Note: When possible, choose organic foods. Pesticides, herbicides, and fungicides can detox through the skin and aggravate breakouts.

Supplements that Support Clearing Acne

Foods That Commonly Trigger Acne

Checking ingredient labels is essential—many acne triggers hide in processed foods.


Common Acne-Inflaming Foods

  • Iodized Table Salt
    Packaged foods, fast food, chips, seasoning blends

  • Whey & Dairy Products
    Non-organic milk, cheese, yogurt, ice cream, protein shakes and bars

  • Soy
    Soy milk, tofu, edamame, soybean oil, processed foods, dressings

  • Peanuts
    Peanut butter, peanuts, peanut oil

  • Inflammatory Oils
    Corn, canola, soybean, sunflower, safflower, peanut oils

  • High-Glycemic Foods
    White bread, pasta, bagels, pastries, cereal, chips, tortillas, white rice

  • Sugars
    Artificial sweeteners and excessive white sugar

  • Seaweed & Kelp
    Especially in supplement or powdered form

  • Supplements to Avoid
    Iodine, iodides, biotin, high-dose B12
    (Also avoid Dasani® water)

  • Pre/Post-Workout Products
    Whey, soy, casein, BCAAs, seed-based proteins, energy drinks, vitamin waters

Surprising Foods That Can Cause Breakouts

Protein powders are a huge hidden trigger for acne.


Many contain whey, soy, biotin, or iodine—all common acne aggravators.


More Acne-Safe Protein Options

  • Amy Myers Paleo Protein (all flavors)

  • Amy Myers Collagen Protein

  • Sprout Living Epic Protein (vanilla & original only)

  • Sunwarrior Protein

  • Garden of Life Raw Organic Protein & Greens

Ingredients change—always double-check labels.

Acne and the Glycemic Index

The glycemic index (GI) measures how quickly a carbohydrate raises blood sugar.

  • High-GI foods spike insulin

  • Elevated insulin increases oil production

  • More oil = more congestion and breakouts in acne-prone skin


Research consistently shows that high-glycemic diets worsen acne, while low-glycemic diets improve acne symptoms.

Focusing on:

  • Whole foods

  • Lean proteins

  • Healthy fats

  • Fiber-rich fruits and vegetables

helps balance blood sugar, hormones, and oil production—supporting long-term clear skin.


Clear Skin Diet – Frequently Asked Questions

Does food really cause acne?

Food doesn’t cause acne on its own, but it can significantly influence inflammation, hormone balance, oil production, and gut health—all of which affect acne. Certain foods can trigger breakouts in acne-prone individuals, while others support clearer, healthier skin.

What foods are most likely to cause acne?

Common acne triggers include dairy, whey protein, soy, peanuts, iodized salt, high-glycemic carbohydrates, processed sugars, inflammatory seed oils, and supplements containing biotin, iodine, or high doses of B12. These ingredients can increase inflammation and oil production in the skin.

Is chocolate bad for acne?

Chocolate itself does not cause acne. In fact, high-quality dark chocolate contains antioxidants that support skin health. Breakouts are more often linked to the dairy, sugar, and salt found in many chocolate products. Moderation and ingredient quality matter.

Why does dairy cause acne for some people?

Dairy can stimulate insulin and androgen activity, which increases oil production in the skin. Non-organic, processed dairy is especially problematic due to added hormones and fortification, making it a common acne trigger.

What is a low-glycemic diet and why does it help acne?

A low-glycemic diet focuses on foods that do not spike blood sugar and insulin levels. High insulin levels increase oil production, leading to clogged pores and breakouts. Research shows that low-glycemic diets help reduce acne severity and inflammation.

Are protein powders bad for acne?

Many protein powders contain whey, soy, biotin, or iodine—common acne triggers. These ingredients can worsen breakouts even in people who otherwise eat well. Acne-safe protein options include collagen-based or plant-based powders without these additives.

Can supplements cause acne?

Yes. Supplements containing biotin, iodine, iodides, or high doses of vitamin B12 are known to trigger acne in many people. Always review supplement labels carefully and consult with an acne specialist before adding new supplements.

Is organic food really important for acne?

When possible, yes. Pesticides, herbicides, and fungicides can detox through the skin and contribute to inflammation and breakouts. Choosing organic foods reduces this burden and supports healthier skin.

How long does it take to see results from dietary changes?

Skin changes take time. While some clients notice improvements within a few weeks, dietary changes typically support clearer skin over several months. Consistency is key, especially when paired with an acne-safe skincare routine.

Do I have to completely eliminate all acne-triggering foods?

Not necessarily. Acne is individual. Some people tolerate certain foods better than others. The goal is to identify your personal triggers and reduce them enough to support clear skin—not to follow a perfect or restrictive diet.

Can diet alone clear acne?

Diet plays an important role, but acne is a genetic condition that usually requires a combination of acne-safe skincare, professional guidance, and lifestyle support. Diet enhances results but rarely works alone.

How can I find out which foods trigger my acne?

Working with an Art of Skin Care certified acne specialist allows you to review your diet, supplements, and lifestyle in detail. Through guided adjustments and observation, triggers can be identified without unnecessary restriction.

Is coffee bad for acne?

Coffee itself isn’t inherently acne-causing. Organic coffee consumed with or after meals is generally well tolerated. Issues usually arise from additives like dairy, sweeteners, or drinking coffee on an empty stomach.

Can drinking more water clear acne?

Hydration supports overall skin health but will not clear acne on its own. Drinking filtered water supports detoxification and skin function, but acne requires targeted skincare and internal support.

Does eating fast food cause acne?

Fast food itself isn’t always the direct cause of acne, but it often contains iodized salt, which is a common and well-documented acne trigger. Iodine can stimulate inflammation and increase breakouts in acne-prone skin. Fast food is also typically high in refined carbohydrates, inflammatory oils, and hidden additives—all of which can contribute to increased oil production and clogged pores. For many acne clients, reducing fast food significantly improves skin clarity.
