On the other hand, low-glycemic diets, which do not dramatically raise blood sugars or insulin levels, are associated with reduced acne severity 10 , 11 , While the research on this topic is promising, more is needed to further understand how refined carbohydrates contribute to acne.
Many studies have found a link between milk products and acne severity in teenagers 13 , 14 , 15 , Two studies also found that young adults who regularly consumed milk or ice cream were four times more likely to suffer from acne 17 , The research to date has focused mainly on teenagers and young adults and has only shown a correlation between milk and acne, not a cause and effect relationship. It is not yet clear how milk may contribute to the formation of acne, but there are several proposed theories.
Milk is known to increase insulin levels, independent of its effects on blood sugar, which may worsen acne severity 19 , 20 , Although there is speculation on why drinking milk may worsen acne, it is unclear whether dairy plays a direct role. More research is needed to determine if there is a specific amount or type of dairy that may aggravate acne.
Acne is strongly associated with eating a Western-style diet rich in calories, fat and refined carbohydrates 25 , Fast food items, such as burgers, nuggets, hot dogs, french fries, sodas and milkshakes, are mainstays of a typical Western diet and may increase acne risk. It is unclear why eating fast food may increase the risk of developing acne, but some researchers propose that it may affect gene expression and alter hormone levels in a way that promotes acne development 28 , 29 , However, it is important to note that most of the research on fast food and acne has used self-reported data.
This type of research only shows patterns of dietary habits and acne risk and does not prove that fast food causes acne. Thus, more research is needed. Diets containing large amounts of omega-6 fatty acids , like the typical Western diet, have been linked to increased levels of inflammation and acne 7 , This may be because Western diets contain large amounts of corn and soy oils, which are rich in omega-6 fats, and few foods that contain omega-3 fats, like fish and walnuts 32 , This imbalance of omega-6 and omega-3 fatty acids pushes the body into an inflammatory state, which may worsen acne severity 34 , Conversely, supplementing with omega-3 fatty acids may reduce levels of inflammation and has been found to reduce acne severity While the links between omega-6 fatty acids and acne are promising, there have been no randomized controlled studies on this topic, and more research is needed.
Chocolate has been a suspected acne trigger since the s, but so far, no consensus has been reached Several informal surveys have linked eating chocolate with an increased risk of developing acne, but this is not enough to prove that chocolate causes acne 38 , Exactly why chocolate might increase acne is unclear, although one study found that eating chocolate increased the reactivity of the immune system to acne-causing bacteria, which may help explain these findings While recent research supports a link between chocolate consumption and acne, it remains unclear whether chocolate actually causes acne.
Whey protein is a popular dietary supplement 43 , It is a rich source of the amino acids leucine and glutamine. These amino acids make skin cells grow and divide more quickly, which may contribute to the formation of acne 45 , The amino acids in whey protein can also stimulate the body to produce higher levels of insulin, which has been linked to the development of acne 47 , 48 , Several case studies have reported a link between whey protein consumption and acne in male athletes 50 , 51 , Another study found a direct correlation between acne severity and the number of days on whey protein supplements These studies support a link between whey protein and acne, but much more research is needed to determine whether whey protein causes acne.
It has been proposed that acne is, at its root, an inflammatory disease 54 , This is supported by the fact that anti-inflammatory drugs, like corticosteroids, are effective treatments for severe acne and that people with acne have elevated levels of inflammatory molecules in their blood 56 , 57 , One way that food may contribute to inflammation is through food sensitivities, also known as delayed hypersensitivity reactions Food sensitivities occur when your immune system mistakenly identifies food as a threat and launches an immune attack against it This results in high levels of pro-inflammatory molecules circulating throughout the body, which may aggravate acne Since there are countless foods that your immune system could react to, the best way to figure out your unique triggers is by completing an elimination diet under the supervision of a registered dietitian or nutrition specialist.
Elimination diets work by temporarily restricting the number of foods in your diet in order to eliminate triggers and achieve symptom relief, then systematically adding foods back while tracking your symptoms and looking for patterns. When hormone levels are increased, our skin produces a substance called sebum which clogs our pores with oil and bacteria, eventually causing painful breakouts. Binge drinking can also wreak havoc on our immune systems which usually help fight off any bacteria causing ac.
Of course you should always drink in moderation, but for those who are more prone to breakouts than others, keep drinking to a minimum. This extreme overdose of insulin increases the production of oils in the skin, which lead to your follicles and pores clogging up with sebum — as mentioned earlier. Alongside the Inflammatory effects that are caused by a spike in insulin, this creates the ideal environment for P.
Acnes bacteria to thrive, triggering a nasty breakout. Usually comprised of french fries, hamburgers, pizza and all other grease filled finger food — the high saturated fats and processed ingredients can completely throw off your hormonal balance and blood sugar levels. If you have a craving for your favorite fast food, try making your own version at home.
Swap baked for fried potatoes and opt for white meat instead of red in your burger. Our dear old friend chocolate has long had a bad rap as the leading cause for all our unsightly blemishes.
So today I will be highlighting 8 foods that you may want to pull out of your diet if you struggle with acne. What Is Acne? Acne is not all that well understood, even by scientists. Think of your pores the small holes in your skin as pipes to the oil glands underneath your skin.
But these complex processes are all affected greatly by simple changes in diet, so be careful about what exactly you put in your mouth. Want naturally radiant skin? Click here to grab your copy! What Causes Acne? As you may have been able to piece together, when too much oil sebum is produced, a plug is formed with dead skin cells gross! When the right amounts of insulin and other chemicals are produced, your sebum production should remain consistent — leaving you zit-free.
So without further ado, here are eight acne-causing foods to immediately stop eating! Bread Bread is problematic for many reasons. But when it comes to acne-causing foods, the main culprit here is gluten.
Gluten can not only lead to small intestinal damage, but it also increases systemic inflammation. In addition, many scientific studies have linked psoriasis to gluten sensitivity.
Bagels Continuing our gluten theme here, bagels are another widely reported culprit of acne development. This expands beyond bagels and includes pasta, refined grains, white flour, and other acne-causing foods high on the glycemic index. This is one of the many reasons why Paleo-friendly carbs like sweet potatoes are a much better choice.
Check out the Day Paleo Meal Plan if you need help on deciding what exactly to eat! Potato Chips Potato chips made with white potatoes are one of the most popular junk foods in the United States. The reasoning here is largely the same as our first two points: chips contain far too many carbs, produce a quick insulin spike, and lead to systemic inflammation.
On top of that, the industrial seed oils used in making potato chips are very high in omega-6 fats, which is very bad news for your body. This pan-seared tuna steak is delicious, loaded with omega-3 fatty acids, and is just one example of the many better dietary choices out there.
