If you ask your dermatologist or doctor if you diet can cause acne the most likely response is probably no. This is far from the case and in fact, if you think about it, what you eat can definitely cause or contribute to a problem with pimples. Generally speaking you want to eat a diet that is free or has the minimal amount of refined sugars, so this means you should stay away from processed foods, sugary drinks and candies that have artificial sugars such as high fructose corn syrup. There has been recent research that shows there is indeed a link between eating refined and processed foods and increased insulin levels. This in turn has shown to lead to encourage the production of hormones in your body which can stimulate the skin to become oily and increase the chance of blockages, bacterial buildup and skin inflammation, all of which can cause or exacerbate acne problems.
So why is it that if you ask a dermatologist, they’ll likely tell you that diet has nothing to do with causing acne and breakouts. This is basically the official position of the North American Academy of Dermatology. Sadly, this an inaccurate myth that has stubbornly endured because of a handful of flawed and insufficient studies conducted more than three decades ago. A common argument you here in this debate about the role diet plays in causing acne is that both individuals eat a comparatively healthily and those who indulge in fried food, chocolate, pizza etc and have unblemished skin, so there is no correlation between acne and food. This view point neglects that possibility that if you’re inclined to get acne, diet can worsen it. You have heard many anecdotal stories of people with acne problems commenting that they have stopped breaking out when they keep a harsh, grain, legume, and dairy-free diet. Also, eating well is not just good for your skin and helps clear your acne but is good for your general health.
One strong reason why doctors and epidermal experts say diet does not cause acne because they can not sell you a good diet. This may sound jaded and even cynical but if you thing about, dermatologists are under great pressure from pharmaceutical corporations to prescribe antibiotics, topical creams and other treatments. Also, drug firms fund most acne research and if a link between acne and diet were discovered it would not benefit them because pharmaceutical companies don’t sell food. Most of the research around the causes of acne is extremely biased.
From a logical standpoint, it should make sense that that diet has a lot to do with attaining skin that is clear and healthy. The mechanisms that cause acne are known: first there is a blockage of the pores by dead epidermal cells which secondly leads to a disproportionate production of skin oil. Third, these conditions inevitably lead to an infection of the blocked pore by bacteria and finally irritation of the pores and surrounding tissue creates various pimples that we all hate which are whiteheads, blackheads and your common zit. This is typically where skin specialists and dermatologists stop – they treat these symptoms by prescribing creams to stop bacteria from colonising blocked pores or to soak up additional oil and dry out the pimple. But at the end of the day, they do not address the underline cause of the acne.
There’s been recent research showing that eating a diet rich in refined carbs and sugar leads to a boost in insulin and an insulin-like expansion factor called IGF-1. This in turn leads to a surplus of male hormones, which stimulate the skin to excrete big quantities of sebum. Sebum is a grease-like substance which encourages the growth of bacteria which causes for acne. The scientists think the modern Western diet is at fault. Refined carbohydrates / sugar ( cereal, bread, pasta, rice, crackers, sugar ) make up a very important component of our diets. These foods have been show to cause insulin levels to spike during the day. Whenever insulin is heightened, levels of IGFBP-3 ( insulin-like expansion factor binding protein three ) are reduced. IGFBP-3 is an activating chemical that controls skin cell death and hinders pores from becoming blocked by the working to remove dead epidermal cells. Increased insulin is definitely not good when you are trying to control your acne. We know that when insulin levels are heightened, it also increases IGF-1 ( insulin-like expansion factor one ), which promotes hormones that make your skin oilier. At the same time increased insulin levels impedes IGFBP-3 from acting properly and impedes the normal process of you body cleansing itself of dead skin.
Inflammation of the skin is a very important underlying contributor to acne and we all know that a diet loaded in omega-6 plant oils and low in omega-3′s, is pro-inflammatory and also leads to the production of IL-1 alpha ( interleukin-1 alpha ). Too much circulating IL-1 alpha causes skin cells to clump up together and block the pores. In addition, the affects of zinc, a vital anti inflammatory mineral, is diminished by dairy goods. The huge dose of concentrated calcium not only meddles with zinc assimilation, but the protein in dairy strongly excites insulin emission.
In conclusion it is a logical argument for a link between diet and acne. The steps are:
1) Refined carbohydrates / sugar leads to increases in insulin levels
2) More insulin results in the stimulation of hormones that create more sebum and oily skin
3) Oily skin traps bacteria and dead skin cells which cause acne.
