Does Chocolate Cause Acne?

August 25, 2019


“Does Chocolate Cause Acne?” Acne affects nearly 1 in
10 people in the world, making it perhaps the eighth
most prevalent disease worldwide. What’s the role of nutrition? Well, go back a century
and dermatology textbooks were recommending various
dietary restrictions. For example, recommending
those with acne avoid foods like pork, sausage, cheese, pickles, pastries, sweets,
cocoa, and chocolate. Yeah, but old-timey medicine
was full of crackpot theories. Dr. Kellogg, for example,
blamed acne on masturbation. Nothing a few corn flakes
couldn’t fix though… Population studies have
found associations between acne and the
consumption of foods like dairy, sweets, and chocolate, but you don’t know if
it’s cause and effect… until you put it to the test. There have been high quality reports, like the Harvard Nurse’s study, that looked at nearly 50,000 women and found a link between adolescent
milk drinking and acne, particularly skim milk, something that’s been found
for teenage boys as well. They thought it might be the hormones in milk that were responsible, but it could also be
the milk protein, whey, of which they add
extra to skim milk to make it less watery, which may play a role directly in acne formation or
as hormonal carriers. That would explain cases like this: where whey protein
powders were implicated in precipitating acne
flares in teens who had acne that just didn’t
seem to want to go away until they stopped the whey. It doesn’t appear to just
be a protein effect, since soy protein
supplements, for example, did not seem to cause
the same problem. But, for dairy, in terms
of interventional studies, all we have are these
kinds of case series. If you do a systematic review
of acne and nutrition, you get results like this for dairy: out of the 20 or so papers
on acne and dairy out there, about three-quarters
suggest adverse effects, and the remainder report no effect, with no studies suggesting
a beneficial effect of dairy on acne; so, you could look at
this and conclude a dairy-free diet is worth a try. But, this is based
on low-grade evidence, level C and D evidence, where C is like the
population studies, and D is kind of like those
series of case reports. What we want ideally are randomized interventional studies,
level A and B evidence, which we don’t have for dairy, but we do have for chocolate. When it comes to acne, no food is more universally
condemned than chocolate. So, if you’re the Chocolate
Manufacturers Association, how are you going
to design a study to make your product
not look so bad? Well, you can always use
the old drug company trick of pitting your product against something even worse; and so, they fed people chocolate bars versus
fake chocolate bars made out of a partially
hydrogenated vegetable oil: trans fats. So, make it have more sugar, throw in some milk protein, and make it 28% pure trans fat laden, Crisco-like vegetable shortening. And surprise, surprise there were just as many pimples on the fake chocolate bars, allowing them to conclude
that eating high amounts of chocolate is A-OK when it comes to acne. And, the medical community fell for it. “Have we been guilty of taking candy away from babies?” “Too many patients harbor the delusion that their health can somehow
be mysteriously harmed by something in their diet.” That original study “finding
that chocolate consumption supposedly does not
exacerbate acne has continued to remain
virtually unchallenged for decades and continues to be cited” even in recent reviews. For example, this pediatrics journal. Years ago, it was demonstrated that chocolate consumption
had no effect on acne. “This serves as a cautionary example of how ‘research-based evidence’ should be vigorously scrutinized prior to being incorporated
into clinical practice.” Just because something
is published in the Journal of the American
Medical Association doesn’t necessarily mean
it’s a good study, especially when industry
interests are involved. Maybe we should be
telling acne patients to try cutting down on not
only the sweets and the dairy but also the trans fats found in partially hydrogenated
vegetable oils, but we can’t be unequivocal in our advice to acne sufferers on foods to include or exclude until… they’re put to the test
in well-designed randomized controlled clinical trials. But there simply weren’t any such trials on acne, until… NOW, which we’ll cover, next.

    I used to have really bad acne and eventually some ugly basal skin cancer warts across my face. Ever since going plant based all of that went away which was pretty amazing. Everyday I could see and feel the warts getting eaten away, and the acne melting down until just flaking away like dead skin. Wish I knew about this years ago haha, but I'm glad I know about it now.

    Cocoa I never found to cause acne in me post going the change in diet, but if ever I eat anything animal based I get a pimple popping up somewhere without fail haha. Told my brother about it and it was the same way for him.

    Even if I mix in merely 2 tablespoons of raw cacao nibs into some mixture, I end up with more blackheads the next week sometimes even big fat inflamed cystic bumps. I know it's only an anecdote, but one I've seen so many times, I'm not taking any chances giving my self a randomized double blind placebo control trial. But I'd still like to know what the scientists found.

    Never had acne, but I do get pimples if I ruin my diet for two – three days in a row and eat stuff like cheese, chocolate, wine.. usually it happens during holidays like Christmas or thanksgiving . When I get back on track with the diet and eat plant based all pimples and breakouts go away in a heartbeat .

  • Reply Luka Brkljačić March 16, 2018 at 3:17 pm

    One word people "hormones". You can lower the precent of acne by some diet regime, but, something that will work for you not might work for me, people are little bit different in that way. I am 23 year old and have an acne problem all over my back and a little bit over the chest since 15. Now I am using something called "Oranozol shampoo (ketoconazolum)" it is a shampoo for dandruff, but it also works for acne, dermatologist prescribe me this a few month ago, but it is a temporary solution. A lot of people in medical fields told me that only after your hormones got balanced your acne problem will go away to and in every human being is about until 25-30.
    Thats what I had been told

    My guess is that >70% cocoa chocolate is going to be okay, even beneficial for acne conditions, due to cocoa's anti-inflammatory properties. Milk chocolate will be problematic because of the dairy component. 😀

    Cocoa / Cacao is High in Oxalates, Histamines & Mold Mycotoxins. Many foods high in Oxalates can cause acne, especially if you exceed the limit your body can handle. Also Glyohosate(Roundup herbicide) converts down to Oxalate!! so it's accumulating in people & joints too causing chronic pain, so peeps genetically unable to break down Oxalates in body, can't handle eating foods HIGH in Ox anymore.

    Dr G, I appreciate all the hard work you do to get good information out, but these cliffhanger videos are Not cool. You may find it to be cute and humorous, but for someone who is trying to help a loved one through a debilitating disease, this can be very frustrating. I realize acne is not a debilitating disease but you have been doing this type of thing more commonly on other more serious topics as well. Just a suggestion.

    Ive been vegan for 5 years I eat everything im supposed to and STILL HAVE ACNE. I eat beans, whole grains, a ton of veggies, fruit, some nuts( very small amount) and no oil or processed junk also 99% of what I eat is organic. I do no drugs or alcohol and also workout and run 6 days a week. I sleep well and drink only water. So clearly diet alone does not heal everyone.

    I am trying to figure out the relationship between food and libido. When I eat whole plant-based food, I am realize how high my libido is. I masturbate about 10 times per day. But as soon as I eat some raw, cold cheese, my libido becomes lower to a point which is tolerable, and I can continue doing my everyday activities. I also like to compare this to a time when I tried a single tablet of xanax about 6 years ago, and my libido was at its lowest point ever; it was basically gone. My libido was virtually indistinguishable. I'm going to continue whole plant-based food and occasionally have some cheese from time to time just so my libido stays right in the middle between these two high and low points. I really wish there was more research showing the relationship between libido and the foods we eat.

    I think the chocolate and whey theories are true. I used to be a hardcore chocolate binger (milk chocolate) before going vegan. I could eat a whole chocolate bar in one sitting. My acne was terrible. I still notice that I get pimples sometimes after eating cocoa-heavy meals. Also my face looks best when I eat lots of fruit and get more sun (with reasonable SPF ofc), so during summer.

    One possible complication with regards to chocolate and acne. Lots of people touch their faces. So, if they are eating chocolate and touching their faces, they are getting trace amounts of that on their face. My point is that suppose you DID find a strong correlation between eating chocolate and acne, it might actually be a result of face touching, not ingestion.
