I've read a number of personal accounts on this site. Not many people have had success clearing their skin just w/ diet, including me.

 

It's clear to me that certain foods don't aggravate acne; the absence of particular substances does. Anyway, if somebody has severe acne, it's most likely due to their genetic makeup, and I'm not too confident that diet can change it.

Have you not heard of epigenetics? Your genetics manifest based upon your environment. There is no dispute that acne, rosacea, eczema ect. Are hereditary conditions but their power of manifestation and severity is determined by the food and lifestyle (circadian rhythm ect) of the person.

You likely did not stick to your diet change long enough or didn't do the right diet. Your acne would be in remission if you had

We live in a world where everything moves by the speed of light. We want fast Internet, fast streaming, fast relationships, fast food, fast money and fast cars. We have no time to wait for solutions for tomorrow, let alone weeks or months. We want quick fixes and magic pills. We want to go to the drugstore grab a bootle of pills and wake up tomorrow 7 inches taller, with no acne and bigger breasts.
Furthermore, if acne is due to our diet, this would mean that it is our own fault we got it. It's way easier to blame it on genes, society, makeup, gmo, tap water or whatever.

..And let us not forget acne is a billions dollar industry. If people started to fix acne with diet pharmaceutical will lose money, shareholders will get mad, acne.org will be history because no one needs to buy benzoyl peroxide, moisturizers, cleansers, masks and oils.

No one making money on acne want you to know the link between diet and acne is rock solid, they can't suddenly patent carrots and tomatoes, you know. It is better business for them if we continue to get acne, instead of getting clear.

Because for most people the acne is hormonal (genetics, age and life stage, sex, health problems such as PCOS) and environmental (stress, weather, improper hygiene/ routine and habits)

And although diet may worsen someones acne it doesnt really address the root of the problem. Some people wih food allergy who have acne might associate the two but acne is not an allergy it is a separate issue. Personally I have never noticed a difference in my skin depending on what I ate before i started using medication.. if there was any percieved change it was miniscule.

I got bigger results if I changed up my routine. A lot of outdoors activity and exercise definitely helps my skin as well as when im on holiday in a warmer climate.

I dont want people to feel paranoid about what they eat because they think it will give them acne.. unless you have an allergy but you shouldnt be eating that thing in the first place. A lot of people also pay to get tested for allergies because of acne and its a waste because most come out clear and later find out they have pcos or some other illness or they just dont know how to take care of their skin (or a mix of both)

So no i dont think diet is that effective. Obviously a balanced diet will give you nutrients which will help regulate your hormones to some extent in a way thag chocolate cake might not...

But green smoothies wont help get rid of toxins lol they just make you feel healthier and help you go to the loo better

In every mammal cell there is function called The PI3K/Akt signaling pathway, sometimes referred to as the mTOR pathway.

The mTOR pathway is increased in patients with PCOS(1)

Blood cholesterol is controlled by The mTOR pathway (2)

Inhibition of the mTOR pathway is why the drug Metformin works in patients with diabetes (3)

Inhibition of the mTOR pathway is used in several types of cancer treatments (4)

Increased mTOR is seen in people suffering from obesity (5)

Hyper activation of The mTOR signaling pathway is thought to play an important role in Alzheimers d. (6)

Hyper activation of the mTOR signaling pathway is the cause of acne (7, 8)

The mTOR pathway is up regulated with western diet (9)

The mTOR pathway can be regulated via diet (10)

The mTOR pathway can be regulated via exercise (11)

Several types of acne medications such as Benzoyl Peroxide and isotretinoin is acting as inhibitors of the mTOR pathway in human skin cells (12)

Hormones can be altered with diet (13)

SHBG (Sex Hormone Binding Globuline) is interrelated with cholesterol (14) and therefore with mTOR

SHBG is interrelated with insulin resistance (15)

Ketogenic diets can inhibit The mTOR pathway (16)

Inhibition of the mTOR pathway increases lifespan in mammals (17)

Probably because it's something really difficult to say conclusively that this or that diet is the cause and eating this or that will cure you. There probably is no specific diet that will work for everyone in the exact same way due to genetic differences in people. Peoples genes will respond differently to different environmental stimuli including food and nutritional stimulus.

At least Esney is someone else here who understands the vast physiological based factors that are compounding in the equation of acne-free living....

People just believe that a topical/oral supplementation or treatment protocol that treats the symptom is all that is required. Also its very common for the science behind nutrition to be overlooked. Just too complex of a problem for some...

AMPK heterotrimer down regulation/modulation is only the beginning..

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ This is just comical.

I would like to ask what methods did you utilize in your personal attempt at establishing an already validated correlation between skin health and nutritional intake?

"I Actually never see overweight people with acne." Wow.....

Your post was extremely negative in nature and doesn't help personify what this community attempts to provide to disgruntled peeps looking for answers.

Let me guess, only the posts that agree with your viewpoint are helpful and everyone else should shut up, right?

Huh? Anyways! Here is what I read that you originally posted, "I have had no success with linking acne to diet and have tried for years.." You were making a generalized claim using acne in a very generalized manner. Now after my reply you then made the statement, "Show me absolute proof that diet is the casue of acne for every person that has acne and for every different type of acne..." That is a very different statement than the aforementioned one. You preach for the validation that diet is the cause of acne for every person that has acne, but your former post was highlighting your personal endeavor on establishing a link between diet and acne.

Anyways.... I was just pointing out that negativity does nothing regardless of how ostentatious the mumble was. My apologies! I don't think I'm right or wrong and I don't consider myself a fan of expressing bigotry when someone else makes a conflicting post...

I like your style. Nice work.

I had a super diet w/ my best body during my worst acne. fact

I'm currently doing pretty much everythingincluding diet, exercise, creams and antibiotics to clear my skin.

Are you not listening? Those fat people don't have acne because they don't carry the gene(s). You on the other hand have to work 100% harder than the average person for clear skin.

^^Just stating a fact that I had just as bad or worse acne when I watched my diet the most. I still watch my diet since I enjoy a fit body very much, but i know its not gonna keep me clear alone.

The city air, crap in the water, nonstick cookware, plastics........there's a zillion things that have been linked to acne that aren't really food related. Working or spending a lot of time in a hot environment, being a cook, doing any kind of dirty work.......your job and environment will cause u to break out waaaaaay more than food.

I'm not making excuses so I can eat a bunch of crap either. I NEVER eat fast food, greasy food, sugar or simple carbs. See my crazy food thread to see how hardcore I am about keeping my kisser clear.

For me and many many others, diet IS the root problem. I eat apples or soy, I breakout. I eat carrots and sweet potatoes, I don't. I had severe cystic acne for 7+ years. The worst. Diet completely cleared my skin. I have Candida overgrowth and leaky gut. I can cure this through diet.

Just because diet didn't work for some of you on here, doesn't mean it won't work for anyone else. Diet is one of the main causes of acne. Study nations across the Earth, and then look at the United State's history, and tell me our food can't cause diabetes, acne, digestive issues, cancer, and all this other bullshit we're DYING FROM! The thought that diet has nothing to do with acne is ludicrous!

Mind you, it's a billion dollar industry. Cancer, diabetes, heart disease, and acne.

I had BAD acne. Bad.

I have a thread under Diet and Holistic health that talks about what I did in detail, and even an explanation on why I eat certain things. It took a few months for me to perfect it, but my skin is actually clear now. Its absolutely unbelievable. I included PICTURES so you guys could see how bad my skin was. If you change your diet for two months or less, try again. I say give it at least 3 months!!! There is a lot of proof out there that we put KRAP into our bodies, and that has huge effects on our health. Even though acne was my main issue, my body is a LOT healthier and I have learned so much about nutrition. My skin has done a 180. It is possible to clear your acne with diet changes, I have proof. CLEAN BODY INTERNALLY = CLEAN SKIN

 

I had BAD acne. Bad.

I've studied nations across the world and acne is hardly just a western problem. It is a problem in the third world as well - same with cancer and the other problems you mentioned. Studies show that problems like cancer are WORSE in other parts of the world that don't have the "western" diets everyone on here is complaining about.

 

"Cancer now accounts for more deaths worldwide than HIV/AIDS, tuberculosis and malaria combined. Of the 7.6 million global deaths from cancer in 2008, more than 55% occurred in less developed regions of the world. By 2030, 60-70% of the estimated 21.4 million new cancer cases per year are predicted to occur in developing countries."

 

- http://www.worldcancerday.org

Actually, the "western" diet has reached all regions of the world. Even some of the smallest countries on planet Earth. Yes, that includes third world countries, too. There is this one island country called Nauru that lives off of unhealthy, greasy, "western" food, and over %80 of them are Obese and many have missing limbs due to diabetes. The United States is actually one of the leading countries in the world for cancer rates, despite the diet having gone worldwide. So no, those statistics aren't surprising, especially considering the first world population is the minority.

Meanwhile, countries like Edit: have the lowest rates of cancer, and are thriving off great diets and lifestyles. (not saying diet is the only cause, cuz it isn't)

1. Western diets ARE in many third world countries, and has reached all regions of the world

2. Some of the smallest nations in the world live off "western" diets

3. The United States still remains a world leader in rates of cancer cases, sitting at #6

4. first world countries are the minority, which makes those statistics shocking.

5. I fucked up with Niger, Yes I fucked up with Niger, Yes I fucked up with Niger In fact, Yes I fucked up with Niger! is the lowest in the world.

Science:

"(..)the Kitavan Islanders of Papua New Guinea and the Ache hunter-gatherers of Paraguay. Additionally, we analyze how elements in nonwesternized environments may influence the development of acne.(..)Of 1200 Kitavan subjects examined (including 300 aged 15-25 years), no case of acne (grade 1 with multiple comedones or grades 2-4) was observed. Of 115 Ache subjects examined (including 15 aged 15-25 years) over 843 days, no case of active acne (grades 1-4) was observed." (1)

Science: "Two reports have suggested that acne prevalence increases as populations adopt a Western diet through migration or cultural change. Reports of northern Canadian Inuits made no mention of acne until acculturation with their southern neighbors and subsequent increases in soda, beef, dairy products, and processed foods, after which the acne prevalence increased. Pre-World War II Okinawans, who traditionally followed a diet of sweet potatoes, rice, and vegetables, together with some soybeans, but little meat, reported an increase in acne prevalence after adopting a diet high in animal products.^"

Science: "Freyre et al. compared acne prevalence in three Peruvian populations, including indigenous and white populations (n = 2214). Among 1218-year-olds, the indigenous population showed a significantly (P < 0.001) lower acne prevalence (28%) than the white population (45%) or those of mixed ancestry (43%). Each adolescent group had a lower prevalence of acne than that reported in 1218-year-old Americans.^"

^If you are going to argue scientific evidence then it is usually adviced to source your contrasting statements.^

Before this arguement becomes hostile everyone must take into consideration that the world of medical science and the participation is called, "Medical Practice."

Hence the word practice. There is a study that contradicts every study. There is a different set of defined variables to every study as well as different mistakes in controlling environmental influences on results.

A good example is the recent approval of Addyi for the treatment of hyposexual desire disorder. (The female equivalent of Viagra/Cialis) Most probably didn't realize the case study involved 23 men and 2 females. Yet the drug was still approved by the FDA. ( a lot of corrupt marketing and negative pressure was a backdrop for its approval) That doesn't even go into consideration that it was originally developed as an anti-depressant in the category of NDDI (norephedrine-dopamine-disinhibitor) as well as having agonist expressions to opoid receptors.

I sourced the authors.

Oh! Oops! My apologies I completely missed the reference to Medline, EMBASE etc.

I should have been more specific, but I was wanting to read the actual scholary articles. Don't worry about the full-article preview restriction as I can use my university account to get access to these studies. So please please shoot me a few links on here or we can continue our conversation via P.M. I'm always open minded to reading contrasting data. How else can we learn?

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:

Abstract

BACKGROUND:

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.

]SCIENCE! SCIENCE! SCIENCE!

Let's have a look at this Magin et al. study:

Source http://www.ncbi.nlm.nih.gov/pubmed/15644386

The Magin et al. study is from 2004 and is a systematic review looking at prior studies linking diet among others to acne

"There are, perhaps surprisingly, few studies that examine the role of diet in acne. Three studies have specifically examined the role of chocolate. Grant and Anderson29 and Anderson30 performed trials of chocolate, milk and roasted nuts"

Here is what Magin et al thinks of the above research:

"(..)the trials were small, uncontrolled, had very short follow-up, and inadequate statistical analysis."

Furtheremore:

"Fulton et al. in a single-blind placebo-controlled cross-over trial in American hospital acne clinic attendees and male prisoners31 found no effect of chocolate on acne (or on sebum production or composition). A small study32 of patients with acne (16 subjects and 13 matched controls) found no difference in sugar consumption between the two groupsthough patients with seborrhoeic dermatitis had higher levels of sugar consumption."

The Grant/anderson study (29) was carried out in 1965

The Anderson study (30) was carried out in 1971

Fulton study (31) was carried out in 1969

The small study referred to in (32) was performed by Bett in 1967

FACT:

The Magin et al. study is from 2004

The above research (29)(30)(31)(32) was all carried out before or in 1971

The above research was studies trying to link acne to diet via linking chocolate>acne; sugar>acne; chocolate milk and nuts>acne.

Magin et al. furthermore states:

"Recently, a reappraisal of the current thinking regarding diet and acne has been proposed following a cross-sectional study of acne in native, non-westernised New Guinean and Paraguayan populations.34 This study showed no cases of acne in either of these populations, and this was contrasted with prevalence of acne in western populations. It is proposed that western diets, with characteristically high glycaemic indexes, lead to hyperinsulinaemia and a resulting cascade of endocrine consequences (increased androgens, increased insulin-like growth-factor 1, altered retinoid signaling pathways) which mediate acne pathogenesis.34,,35

A further recent study has demonstrated a correlation of worsening diet quality (during a pre-examination period in university students) and exacerbation of acne.36 The main factor examined in this study was the effect of examination stress on acne severity, and the dietary variable measured was self-assessed diet quality (on a scale 14) rather than a validated objective measure of dietary components."

My interpretation of the above is: The recent studies up till 2004 (34 to 36) is inconclusive in the acne-diet relation and there is a need for new and better studies.

So the main question is:

Did we follow up with better studies since 2004?

Yes we did:
