The link between diet and acne

Acne is multifactorial (hormones, genetics, bacteria), but diet plays a role. Blood sugar spikes increase insulin and IGF-1, stimulating sebum production and inflammation. Certain foods can therefore worsen or improve acne.

The low glycemic index diet

Studies show that a low glycemic index (GI) diet reduces acne. Favor whole grains, legumes, vegetables, and avoid refined sugars, white bread, sodas. Low GI stabilizes insulin and reduces stimulation of sebaceous glands.

Dairy products and acne

Several studies link dairy products, especially skim milk, to acne. The natural hormones in milk and growth factors could stimulate sebaceous glands. The effect varies by individual: test a 4-6 week elimination to evaluate.

Beneficial nutrients against acne

Zinc (oysters, meat, pumpkin seeds) has anti-inflammatory and antibacterial properties. Omega-3s (fatty fish) reduce inflammation. Vitamin A (sweet potato, carrots) aids cellular renewal. Gut health also influences skin (gut-skin axis).

Important

Never go below 1200 kcal/day (women) or 1500 kcal/day (men) without medical supervision. Too aggressive a deficit can be dangerous for your health and counterproductive for weight loss.

Guide to Diet Against Acne

Important: Acne is a medical condition. If you suffer from severe or persistent acne, consult a dermatologist. Diet is a complement, not a replacement for medical treatments.

Diet can influence acne by modulating hormones, inflammation, and sebum production. This guide presents the dietary strategies most supported by science.

Strategy #1: Low Glycemic Index Diet

Why it works

High GI foods cause:

  1. Rapid blood sugar spike
  2. Massive insulin release
  3. Increase in IGF-1 (growth factor)
  4. Stimulation of sebaceous glands
  5. More sebum = more acne

Foods to favor (low GI)

  • Grains: oats, quinoa, brown basmati rice
  • Legumes: lentils, chickpeas, beans
  • Vegetables: most have very low GI
  • Fruits: berries, apples, pears (avoid juices)
  • Proteins: meat, fish, eggs (zero GI)

Foods to avoid (high GI)

  • White bread, baguette
  • White rice, white pasta
  • Sodas and fruit juices
  • Candy, pastries
  • Sugary breakfast cereals

Strategy #2: Test Dairy Elimination

How to proceed

  1. Eliminate all dairy products for 4-6 weeks
  2. Observe your skin’s evolution
  3. Gradually reintroduce (cheese, yogurt, milk)
  4. Note reactions

Milk alternatives

  • Almond, coconut, oat milk
  • Plant-based yogurts
  • Plant-based cheeses

Anti-Acne Nutrients

Zinc: the star mineral

Zinc reduces inflammation and has antibacterial properties:

  • Oysters: 6 oysters = 500% of needs
  • Lean beef: 3.5 oz = 50% of needs
  • Pumpkin seeds: convenient snack
  • Crab, lobster

Anti-inflammatory omega-3s

  • Salmon, mackerel, sardines: 2-3 times/week
  • Ground flaxseeds: 1 tbsp/day
  • Walnuts: a handful/day
