Surprising Foods That Cause Acne: The Healthy Food Trap

You meal prep. You steer clear of junk food! You drink your greens. Next, you check out your face in the mirror and see another pimple on your jaw line. This is the healthful food catch. You feel like you’re eating a healthy diet, but your skin doesn’t look the same.

The majority of people, when they have pimples, point to pizza or chocolate. The true offenders are your health food cabinet. They are in your gym bag! They are sneak fed into your morning smoothies. This is why understanding foods that cause acne most people don’t realize can be so important.

Whey protein, skim milk and stealth refined sugars are some of the most surprising foods that cause acne most people don’t realize. These cause acne by causing insulin to spike and triggering up the hormones of IGF-1.

The Science of Diet and Acne

Acne vulgaris does NOT begin on the surface of the skin! It begins in the stomach and intestines. Some foods increase your blood sugar. Your body reacts by producing insulin.

When insulin is high, so is Insulin-like Growth Factor 1 (IGF-1). This is a hormone which stimulates the production of sebum by your sebaceous glands. Sebum is an oily substance which helps to lubricate the skin.

Excessive sebum combines with dead skin cells. This composition stops the hair follicles from opening. The pore turns into an anaerobic environment. Cutibacterium acnes grows in the absence of oxygen. The bacteria multiply. Your immune system responds. This results in hyperkeratinization, redness and pus.

Surprising Foods That Cause Acne

Please note that the following is a list of foods that can induce this hormonal sequence. These foods are believed to be health or harmless for most people.

• Whey protein powder
• Use skim milk and low fat dairy products
• Clean up the agave nectar and hidden sugars
• Eat seaweed snacks and foods high in iodine
• Vitamin B12 supplements at high doses
• Flavored granola bars
• Commercial fruit smoothies

Whey Protein Powders

This pain is well recognized by bodybuilders and fitness enthusiasts. You start a new workout program. You are taking 2 scoops of whey protein per day. After a month you develop severe, cystic acne in a line down your neck and jaw.

Whey protein is a by-product of milk. Has bovine IGF-1. It also leads to a faster rise in human insulin levels than table sugar alone. This mix causes your sebaceous glands to over-activate.

This doesn’t occur with plant proteins. The pea and rice protein blends deliver the amino acids you need to repair your muscles, without any hormonal side effects.

Skim Milk and Low-Fat Dairy

People select skim milk because they want to reduce fat. They get something more harmful to their skin.

In the skimming, the dairy producers change the milk’s hormonal profile. Skim milk has a higher GI than whole milk. It leads to a rapid rise in insulin. It also has androgen precursors. These precursors are turned into testosterone in the body. Sebum production is triggered by the action of testosterone.

Whole milk is a fat milk. Fat delays the digestion of the milk sugars. This results in a smaller insulin spike. If you can’t drink milk, then full-fat is better for your skin.

Agave Nectar and Hidden Sugars

Prevents use of white sugar. You put agave nectar in your tea. You think you win. You do not.

Agave nectar is made of a tremendous amount of fructose. Fructose is not a blood glucose stimulator but increases systemic inflammation. It also leads to advanced glycation end-products. These end-products result in the destruction of collagen and inflammation of the skin.

Granola bars are another danger. It is organically or naturally packaged. The ingredients include brown rice syrup, honey or cane sugar. These hidden sugars produce the same insulin rush as a candy bar.

Think of an entire apple. Fructose is found in an apple. It’s also packed with fibre. Fiber forms a matrix in your stomach. This matrix will slow down the absorption of sugar. The fructose is absorbed slowly into your blood. No insulin spike. Removing the apple fiber by juicing. You receive a cup of sugar water.

Seaweed Snacks and High-Iodine Foods

Thyroid activity depends on the presence of iodine. You need it. Excess can irritate your pores.

Some foods, such as kelp snacks and dulse as well as some seafoods, are very high in iodine. Extra iodine is removed from your body in the sebum excreted by the sebaceous glands. The iodine comes out through the pore and irritates the wall of the follicle. This leads to localized inflammation (papules).

High-Dose Vitamin B12 Supplements

Vitamin B12 is important for the health of the nervous system. It’s available in animal foods. Several take additional B12 to boost energy.

High-doses of B12 have been demonstrated to shift skin microbiome. The vitamin changes the metabolic activity of Cutibacterium acnes. The bacteria start producing inflammatory molecules called porphyrins. These porphyrins cause acne in those with a genetic predisposition to it.

This change will not occur if you take B12 from a fish or egg. It’s the concentrated doses in energy drinks and supplements that’s causing the issue.

Acne Triggers vs. Food Allergies

Both these issues are mixed up in the mind of people. The treatment routes are different.

When you have a food allergy, there is a protein called immunoglobulin E. When a person has a food allergy, there is a protein called immunoglobulin E and a person eats a strawberry. Your throat swells. You develop hives. Immediate immune response.

Hormones and inflammation are a dietary acne trigger. You have a whey shake. After 3 days, a cyst develops on your chin. This is a delayed inflammatory reaction.

Getting rid of a food allergy can save your life. If you remove an acne trigger you get rid of your acne. A trigger for acne doesn’t require an EpiPen. You need patience.

Acne Trigger Foods vs. Safe Alternatives

Replace the hidden triggers with the values from this table. Maintain the same number of macronutrients. Make the hormonal effect a change.

How to Identify Your Hidden Acne Food Triggers

The first step in an acne elimination diet is to determine the foods that may trigger acne breakouts. Eliminate dairy and whey for 3 weeks. 2. Maintain a food and skin log. 3. Add one food every 4 days. 4. Observe skin for 72 hours.

• Eliminate whey protein and any dairy products for 3 weeks
• Keep a food and drink diary
• On day 22 reintroduce one suspected food item
• Check your skin for the next 72 hours for any actual pimples
• Record the reaction and proceed to the next food

Never take everything out at once. When you are eliminating dairy, sugar, and meat all at once, you will not be able to determine which caused the acne. Isolate the variable.

Have a special notebook or a food tracking app. On day 1 take a picture of your face. Repeat the picture taking exercise at day 21. Compare the amount of inflammation.

Common Mistakes When Changing Your Diet

Individuals set up their own obstacles. Avoid these traps.

Over-Restricting Calories

You want to get rid of your acne. You stop eating. Your brain is feeling hungry. Your body boosts cortisol levels to keep you awake. Cortisol is also a stress hormone. It stimulates the production of sebum directly. Your acne worsens. Get the calories you need for your basal metabolic rate.

Cutting Out Healthy Fats

There are some people who eliminate avocados, nuts, and salmon from their diet. They are afraid of all fats producing oily skin. Omega-3 fatty acids are healthy and work the other way. They decrease the inflammation of the body. They are useful to strengthen skin cells’ barriers. Keep the avocados. Eliminate trans fat.

Quitting Too Early

There are 28 days in the skin cycle. When you get a pimple, it’s actually weeks in the making. After 1 week, if you resume your elimination diet, you do not get any results. Wait three weeks before judging the outcome of the protocol.

The Gut-Skin Axis and Microbiome Health

Your digestive tract and your skin communicate. This is known as the gut-skin axis, and it is a connection that has been recognized by doctors.

Chronic inflammation in the gut is reflected on the skin. Probiotics and prebiotic fibers help to regulate this system. Sauerkraut, kimchi and other fermented foods are a great source of good bacteria, which are added to your gut. A healthy gut system has a better ability to process sugars. This helps to reduce the insulin surge after a carbohydrate intake.

When to See a Dermatologist or Dietitian

Diet has limits. There is a huge genetic element to acne vulgaris. Even if you think you’ll be fine and have no symptoms of the disease, you may need medical treatment if your parents do.

Look out for certain red flags. If you have acne that leaves behind scars that will never fade, it’s time to visit your doctor. The doctor is needed if you get hard, painful nodules under the skin. Scars will not be reduced by dietary changes.

Look for an “acne dietitian [City]” or a “dermatologist near me”. A registered dietitian (RD or RDN) is able to create a healthy eating plan. They make sure you don’t become deficient in any nutrients during trigger testing. A dietitian consultation in the world will range from USD 100 to 250 depending on the region.

Medications or topical retinoids may be prescribed by a board certified dermatologist. These treatments are effective apart from any diet. They work on the hyperkeratinization and directly on Cutibacterium acnes.

Frequently Asked Questions

Can Peanut Butter Cause Acne?

Peanut butter is rich in omega-6 fatty acids and low in omega-3 fatty acids. This ratio is a promoter of systemic inflammation. Commercial brands include added hydrogenated oils and sugars. All of these factors put together can lead to acne breakouts if eaten in excess.

Do Eggs Cause Acne?

For most people, eggs aren’t a cause of acne. They are not too high in the glycemic index. They don’t cause insulin to rise. Eggs are a common allergen, so if you have an egg allergy, note that some eggs may be coated in oils or butter during the cooking process.

What About Artificial Sweeteners?

There is no research evidence that artificial sweeteners are associated with acne. Sugar alcohols are known to cause gut problems in some. There is a weak association between gut inflammation and skin inflammation.

Is Fruit Juice Bad for Acne?

Yes. Removes the fiber from fruit with juice. If the fruit sugar isn’t accompanied by fiber, it will reach your bloodstream quickly. This results in a huge burst of insulin. Instead, consume the entire fruit, or fruit and skin.

Does Whey Isolate Cause Acne?

Yes. Whey isolate contains less fat than concentrate and the same proteins which stimulate IGF-1. Both can lead to breakouts in sensitive individuals. Avoid animal products.

Why Do I Break Out If I Eat Clean?

Hidden triggers may be ingested. Clean foods include whey protein, skim milk and too much seaweed. Additionally, they lead to serious hormonal breakouts as well.

Is Greek Yogurt Better for Acne?

Plain Greek yogurt contains less sugar and lactose than regular yogurt. It is still a dairy product. It still has hormones which can cause acne in sensitive people.

Stop guessing. Track your food. Eliminate hidden triggers. Wait a month for the process to take effect. If nodular cysts persist, visit your local dermatologist. Have a professional do the heavy lifting and enjoy a well-rounded eating plan.
