Lucas "None of those studies are evidence that diet is the strict cause of acne for everyone." This is absolutely true
Great post. Saved me a lot of footwork in diving into the validity. I definitely got a few theories or rather observational statements that I wouldn't mind getting your input on.
None of those studies are evidence that diet is the strict cause of acne for everyone. I can even quote plenty of studies that give the opposite of what your studies say in the patronizing format you enjoy so much:
Science:
AbstractBACKGROUND:Lay perceptions that diet, hygiene and sunlight exposure are strongly associated with acne causation and exacerbation are common but at variance with the consensus of current dermatological opinion.
OBJECTIVES:
The objective of this study was to carry out a review of the literature to assess the evidence for diet, face-washing and sunlight exposure in acne management.
METHODS:
Original studies were identified by searches of the Medline, EMBASE, AMED (Allied and Complementary Medicine), CINAHL, Cochrane, and DARE databases. Methodological information was extracted from identified articles but, given the paucity of high quality studies found, no studies were excluded from the review on methodological grounds.
RESULTS:
Given the prevalence of lay perceptions, and the confidence of dermatological opinion in rebutting these perceptions as myths and misconceptions, surprisingly little evidence exists for the efficacy or lack of efficacy of dietary factors, face-washing and sunlight exposure in the management of acne. Much of the available evidence has methodological limitations.
CONCLUSIONS:
Based on the present state of evidence, clinicians cannot be didactic in their recommendations regarding diet, hygiene and face-washing, and sunlight to patients with acne. Advice should be individualized, and both clinician and patient cognizant of its limitations.
Magin et all.
Science: The evidence of a major genetic influence on acne should stimulate the search for potential genes that may lead to new therapeutic approaches.
Bataille et all.
SCIENCE! SCIENCE! SCIENCE!
That isn't a study. It's a "review of the literature" and a stupid one at that because it lumps together things that shouldn't be lumped together. The face washing most do is detrimental to acne and everything else to do with your skin as it impairs its ability to function. It's not a leather wrapping and your sebum isn't dead grease. They are made of living cells that do things.
And it doesn't "give the opposite' of what the other studies posted here say. It's conclusion is that "clinicians cannot be didactic in their recommendations regarding diet, hygiene and face-washing, and sunlight to patients with acne. Advice should be individualized"
And their advice should be individualize to a certain degree. But it should always include the advice to eat real, whole, nutrient dense food and avoid/limit high glycemic and insulinemic foods. And anything the individual has an intolerance for.
And the people who put it together have more credibility on here than you do, so I wouldn't call it "stupid".
It still needs to be individualized because the suggestions you have do not work for everyone, even though you think they do because you say so.
Sigh. Diet is as much a "cause" of acne as it is for heart disease, diabetes, many cancers, etc. Almost every other lifestyle related condition, all with a genetic tendency as well. Not because I say so. Because it has been demonstrated in numerous studies (involving actual experimentation with controls) how it affects sebum production & more importantly composition, inflammation, hormones, skin function, your epigenetic tendencies etc. Everything to do with acne formation.
Also, it's important to understand that most doctors & researchers today were educated before they finished mapping our genome and discovered we actually don't have enough genes to control each and every thing. And began to understand the role of epigenetics, enzymes and switches that activate & deactivate. Which they do because of things you do to yourself, such as what you eat. And so they are operating from a faulty paradigm.
And there are a great deal of flawed studies out there. Many have an agenda. Many that don't end with the the desired results never get published. Some are hard to spot. That one was incredibly easy.

Except there isn't a single study that proves that all acne is caused by diet. And the statement you say dismissing the other studies can easily be used against the studies you like where you think it's demonstrated to have a correlation. You can easily just dismiss those by saying they're flawed, have an agenda, etc. as well. That was incredibly easy.
There isn't a single study that confirms all instances of any other health condition are caused by any one thing either. It's ridiculous to expect there to be one. And even more ridiculous to deny the obvious relationship between diet and how your body functions or fails to function. Especially with all the work that's been done to show the relationship between diet/nutrients and each and every factor involved in the condition.
I haven't said ALL acne is caused by diet. No one has. Some can be caused by topicals or environmental pollutants or allergens. Or there's the possibility of a hypersensitivity to demodex mites that some people might have. Although your diet can affect the severity of the inflammatory response.
Some people are hypo or hyper thyroid or have PCOS. Or suffer from stress. Although, again diet affects your thyroid & how you cope with stress. Many people have a combination of things going on. I do. And diet affects most of those things.
Lucas89, I have a hard time understanding why you spend so much time on this particular board, when you stubbornly reject just about everything it stands for.
Because you de-rail conversations with negativity you almost seem to amuse yourself with. And I started getting annoyed seeing sincere people take your negativity seriously and waste their time arguing with you. If you don't believe acne can be controlled and/or healed via diet and holistic health practices, why contribute to this board?
Sadly I think this is true, I just asked my mom because I was wondering and she agreed junk food and fried food causes acne. There may not be any "scientific" evidence but we don't know everything yet. If you go back far enough in time it seems acne was less common among teenagers than it is today. developing countries may not have as much acne because they eat more natural foods instead of processed.
