IT’S CONFIRMED. DAIRY PRODUCTS AND SUGAR CAUSE ACNE.

As our sugar and dairy consumption has increased over the last 100 years so has the number of people with acne. We now have over 17 million acne sufferers, costing our health care system $1 billion a year. Eighty to ninety percent of teenagers suffer acne to varying degrees.

The pimply millions rely on infomercial products hawked by celebrities or over-the-counter lotions, cleansers, and topical remedies. Recent research suggests that it’s not what we slather on our skin that matters most but what we put in our mouth.

Many have suggested a diet-acne link, but until recently it has not been proven in large clinical studies. Instead dermatologists prescribe long-term antibiotics and Accutane, both of which may cause long-term harmful effects. In 2009, a systematic review of 21 observational studies and six clinical trials found clear links.

Two large controlled trials found that cow’s milk increased both the number of people who got acne and its severity. Other large randomized prospective controlled trials (the gold standard of medical research) found that people who had higher sugar intake and a high glycemic load diet (more bread, rice, cereal, pasta, sugar, and flour products of all kinds) had significantly more acne. The good news is that chocolate (dark chocolate that is) didn’t seem to cause acne.

The dietary pimple producing culprits – diary and sugar (in all its blood sugar raising forms) – both cause spikes in certain pimple producing hormones. Dairy boosts male sex hormones (various forms of testosterone or androgens), increases insulin levels, just as foods that quickly raise blood sugar, (sugar and starchy carbs) and spikes insulin.

Androgens and insulin both stimulate your skin to make those nasty, embarrassing pimples. One patient recently told me he would give a million dollars for a pill to cure acne. He doesn’t need to. It seems that for many the cure to acne is at the end of their fork, not in a prescription pad.

While pimples are not as simple as too much milk or sugar in your diet, both have a significant impact. Nutritional deficiencies as well as excesses can worsen acne. Correcting common deficiencies including low levels of healthy omega-3 anti-inflammatory fats, low levels of antioxidants such as vitamin E, zinc, and vitamin A, and including an important anti-inflammatory omega-6 fat called evening primrose oil may all be helpful in preventing and treating unwanted pimples.

I will explain how you can correct and incorporate all of these nutritional elements of your diet and outlines some supplements that will help you fight acne in a moment. But first it is worth taking a deeper look at milk and sugar.

It appears that anabolic or sex hormones in milk contribute to acne …



Stay Away from Dairy and Avoid Acne

One scientist referred to milk as a “complex aqueous, suspended fat, liposomal, suspended protein emulsion”. What we do know is that milk is designed to grow things – namely, babies – and in the case of cow’s milk, calves. It is naturally full of what we call anabolic hormones (the same ones that body builders and A Rod use to grow big muscles, and which cause bad acne).

These are mostly androgens (like testosterone) and growth hormones including insulin like growth factor 1 (IGF-1). There is no such thing as hormone-free milk.

Here’s a short list of the 60-some hormones in your average glass of milk – even the organic, raw, and bovine growth hormone free milk:

20α-dihydropregnenolone

progesterone (from pregnenolone)

5α-pregnanedione

5α-pregnan-3β-ol-20-one, 20α- and 20β-dihydroprogesterone (from progesterone)

5α-androstene-3β17β-diol

5α-androstanedione

5α-androstan-3β-ol-17-one

androstenedione

testosterone

dehydroepiandrosterone sulphate acyl ester

insulin like growth factors 1 and 2 (IGF-1 and IGF-2)

insulin

This is what our government suggests we drink in high doses—at least 3 glasses a day for me, a healthy adult male, according to the mypyramid.gov website. Those guidelines have been strongly criticized by many including leading nutrition scientists from Harvard such as Walter Willett and David Ludwig.

The famous Nurse’s Health Study examining health habits of 47,000 nurses found that those who drank more milk as teenagers had much higher rates of severe acne than those who had little or no milk as teenagers. If you think it is the fat in milk, think again.

It was actually the skim milk that had the strongest risk for acne. In other studies of over 10,000 boys and girls from 9 to 15 years old, there was a direct link between the amount of milk consumed and the severity of acne.

It appears that it is not just the anabolic or sex hormones in milk that causes problem but milk’s ability to stimulate insulin production. It actually may be the lactose or milk sugar in milk that acts more like a soft drink than an egg. Drinking a glass of milk can spike insulin levels 300 percent.

Not only does that cause pimples, but it also may contribute to prediabetes. This is true despite studies funded by the dairy council showing that milk helps with weight loss. The question is compared to WHAT diet – a diet of bagels and Coke, or a healthy phytonutrient, antioxidant-rich, plant-based diet with lean animal protein?

Stay Away from Sugar, Refined Carbs, and Pimples

If a glass of milk causes pimples, that may drive you back to your Pepsi. But not so fast. Recent studies also show that sugar and refined carbs (a high-glycemic diet) cause acne. More importantly, taking kids off sugar and putting them on a healthy, whole foods, low-glycemic load diet resulted in significant improvements in acne compared to a control group eating a regular, high-sugar American diet.

In addition to less pimples, the participants lost weight, became more sensitive to the effects of insulin (resulting in less pimple-producing insulin circulating around the blood). They also had less of the sex hormones floating around their blood that drive pimples. We know that women who have too much sugar and insulin resistance get acne, hair growth on their face, hair loss on the head, and infertility. This is caused by high levels of circulating male hormones and is called polycystic ovarian syndrome but is a nutritional, not gynecologic disease.

But the dietary influences don’t stop there. It is not just sugar, but the bad fats we eat that may also contribute to acne.

Get an Oil Change

Our typical Western diet is full of inflammatory fats – saturated fats, trans fats, too many omega-6, inflammatory, processed vegetable oils like soy and corn oils. These increase IGF-1 and stimulate pimple follicles. Inflammation has been linked to acne, and anti-inflammatory omega-3 fats (from fish oil) may help improve acne and help with many skin disorders.

Balance the Hormones that Cause Skin Problems

The link is clear – hormonal imbalances caused by our diet trigger acne. Our diet influences sex hormones like testosterone, IGF-1, and insulin, which promote acne. The biggest factors affecting your hormones is the glycemic load of your diet (which is determined by how quickly the food you eat increases your blood sugar and insulin levels), and the amount of dairy products you eat. The good news is that eating a healthy diet and taking a few supplements can balance those hormones. Exercise also helps improve insulin function.
