I agree with your intelligent post Hiddy Cheeks!! Yes, sugar/ refined carbs/ gluten/ dairy/ processed foods etc can also lead to acne.
Btw, the reason that I'm so skeptical of the 'genetic causes arguments' is because my dermatologists feed me this 'theory' crap for years, and so I had acne / acne scars for years, as I continued to eat a junk/ western diet & use toxic chemical harsh acne topicals, over washing my wash, wondering why the hell I was still getting and getting acne scars! Most medical doctors are not trained in nutrition. And it is the cornerstone to good health. Essentially, we are made to eat natural foods. Our body does nor recognize chemicals/ processed toxins/ artificial foods/ plastics etc. It will reject these "bioweapons"and secrete them through our skin and organs and cause chronic inflammation, the common cause of disease, infection, scarring etc.
You are going to write off years of research by thousands of people on the causes of acne because of your one, single case study and feel ok saying anyone who doesn't believe a bad diet causes acne is "intellectually challenged"?
Actually, the science in this area is far from settled and there is a significant school of thought to the effect that there is a relationship between diet and acne. See for instance the comments in the article at the link below about acne and the western diet and the criticisms it makes of the now very old studies on which the no diet-acne relationship theory is based.
Also, I don't see why anecdotal accounts can't be useful, especially if there a lot of them. In my case neither my parents nor their parents have / had acne scars. Scarring only appeared in my generation, out of 4 siblings me and my sister have them. Why then if 3 generations of a family share common genes does acne scarring only show up in the youngest generation? Could it be that the older generations were young at a time when junk food and highly processed foods were not as ubiquitous as they are now (by the way, my scar free siblings eat well whereas me and my scarred sister are not so good). And ask any derm and they will tell you that adult acne is becoming more prevalent than it once was. To my mind the most obvious cause of this is environmental factors, most likely diet. But as I said in my previous post this doesn't mean that everyone with a poor diet will develop acne (and vice versa). Diet is only one factor, genetic makeup is the other.
Great post & thanks for the link!
PS Once upon a time, I too so loved my junk food. I was so relieved to hear the "experts" say my acne wasn't due to my diet; so for years and years, I chomped away at McCrapalds, Kentucky Fried Crap, meat galore, artificial deli cold meats, plastic cheeses, processed sauces, potato chip 'bioweapons', toxic aspartame coca-a-rocket fuel etc, pure acid vinegars, coffee, teas, processed cardboard foods, microwave foods etc. I also diligently used the "experts'" toxic, chemical-based topicals & toxic meds & my skin got MUCH worse (as I over washed & over processed my sorry face).
I found out about the diet link to clear skin by accident. I loved animals and made a moral choice to go vegetarian. To my surprise, I noticed it helped my skin. I then got into natural health. I then went "healthy" (mostly raw) vegan as my commitment to the plight of animals increased. And to my utter amazement, my skin started to clear! I researched more into natural therapy and discovered needling. It took years of trial and error, but I finally tackled my scaring. I sincerely hope this information helps others. Sooner rather than later. Even if you choose not to become vegan (initially), please look into minimizing meat products, eating only organic, humanely raised meat/ not processed meat/ not deli meat or only eating free range organic eggs & lots of fresh organic vegan wholefoods like salad, nuts, seeds, green leafy greens, kale, fresh fruit/ veg juices, vegetables, lentils, beans, peas, quinoa, brown rice, hummus, chia seeds, tahini, cayenne pepper, turmeric, fresh coriander, fresh mint, fresh flat leafed parsley etc, flat bread (on occasion if you love bread), rice noodles, sea vegetables, avocado, kiwi fruit, oranges (if you're not allergic to it), tomatoes, cucumber, broccoli, red cabbage, asparagus, superfoods like chlorella, spirulina, barley grass - even baked potato (with the jacket)/ sweet potato/ pumpkin etc
PS Also use lots of fresh lemon juice on your salads & grapeseed oil, flaxseed oil (but avoid flaxseed oil if you're pregnant - instead use a vegan DHA/ EPA/ Omega 3 supplement instead and chia seeds etc).
PPS B12 supplementation is vital for vegans. Even non-vegans are often lacking in this vital vitamin.
Yes, good advice. I like the idea of eating well and I am getting better, but am prone to relapses. My niece is a vegetarian and she serves as a good example for me. I doubt I'll ever give up meat for good but I think there is merit in reducing your meat intake by eating vegetarian several nights a week.
When it comes to food I like the ancient wisdom of Hippocrates quoted in the article: "Let food be your medicine and let medicine be your food". Anyway, I'll quit now as people are getting tired of this, but it is an interesting topic not least of all because we've been sold the "diet does not affect acne" meme for so long.
