Diet and Acne
Home › Diet and Acne
After years of research by scientists, there are still no conclusive studies that prove specific foods to be responsible for acne. Research results from studies conducted over the last 10 years demonstrate that diet does not cause acne, it may only influence or aggravate it. The main contributory factors are usually genetics, hormones and certain medications.
My Personal Experience
I did not quite believe diet would trigger acne outbreaks until I experienced it first-hand. When I was pregnant, I started taking soy milk during my second trimester. Over the 2 weeks of soy milk consumption, I realized that I started to have bumpy complexion and my acne started getting worse.
Initially thinking that the aggravation was a result of pregnancy and hormonal changes, I paid little attention. Yet, I realized that my entire forehead was covered in red pimples, as compared to my first trimester when I would only have random pimples popping up on my face.
I decided to put my suspicion to the test and stopped taking soy milk. I also used SkinLYcious Anti-Acne Bundle to control my acne outbreak. True to my suspicions, my acne cleared up! Thereafter, throughout my pregnancy, I did not have any major outbreaks. From then on, I avoided soy milk and even soy products. Thereafter, I became more conscious about my outbreaks and food intake to see if there’s any co-relation. I also discovered that durians and spicy, greasy food are my ane triggers too.
However, I believe that everybody’s trigger is possibly different. I do not think that everyone’s acne can be affected by diet. Even so, every individual might possibly have different triggers. If you suspect that diet is causing your acne outbreak, try our Elimination Methodology. Do this with only one ’trigger’ food at a time
‘Trigger’ Food List
Again, I must stress that these foods are not definite acne triggers for everybody. I have ranked the ‘Trigger’ Food list according to evidence level, with the top of the list having the highest evidence. The below list is not exhaustive. I have found my own acne triggers that are not listed in this list.
A food’s glycemic load is a number that estimates how much the food will raise a person’s blood glucose level after eating it. High glycemic load food turns into blood sugar very quickly.
Some foods that contain high glycemic load are
- Potatoes (Think French fries, mashed potatoes) White Rice
- Pasta made with white flour
- White bread with butter/peanut butter/skim milk cheese French Bread
- Sweet cakes
- Beverages with high sugar content
- Jelly Beans
- Candy Bars
- Refined breakfast cereal
For the full detailed list, you can refer to international table of glycemic index and and glycemic load values – an extensive list of 2,480 individual food items of different glycemic index and glycemic load values.
In a case control study done in Malaysia, subjects that had acne had significantly higher dietary glycemic loads compared to controls. Researchers from this study concluded that a high glycemic load diet and frequencies of milk and ice cream intake were positively associated with acne vulgaris.
Dairy products include:
- Ice cream
- Any other food that uses milk or dairy products as ingredients
In two review studies of diet and acne, they found evidence that cow’s milk intake increased acne prevalence and severity. In 2005, in a retrospective study in 47,355 adult women, researchers’ inference was that acne was indeed positively associated with milk, especially skim milk, ingestion.
In the above study example that I cited for high glycemic load diet, researchers also concluded increased milk intake would lead to worsening acne.
Some foods rich in omega-6 fatty acids are:
- Vegetable oil such as safflower oil and corn oil
- Mayonnaise and salad dressings
- Deep fried food such as nuggets, fries, fried chicken, etc.
- Cookies, candies, cakes, pastries and muffins
- Dairy and eggs
- Fatty red meat, such as pork and beef
In the review by Ferdowsian et. al., the researchers were not able to find published, large, well-controlled studies that examine the effect of fat or fatty acid intake on acne risk. However, a study has shown that omega-6 fatty acids are pro-inflammatory and their pro-inflammatory mediators have been associated with acne. Most high dietary fat diets are also high in glycemic load.
The review by Ferdowsian et. al., did not find any evidence to link chocolate to worsening acne. In 2011, Block et.al reports her investigations where 10 men aged 18 to 35, who had previously been diagnosed with acne, ate as much pure chocolate as they wanted in one sitting, up to a maximum of three 4-ounce candy bars. Then they were told to follow their normal (chocolate-free) diet for a week. The candy bars were pure chocolate, made of 100% cocoa. At the start of the study, the men had an average of three pimples. By the fourth day, the figure had jumped to 13 and by the end of the week, they had an average of 18 pimples.
However, the above results are preliminary and it’s too small a sample size to conclusively point a finger at chocolates for worsening acne. Some researchers blame it on the milk that is found in milk chocolates or the high sugar content in some chocolates.
The evidence for soy is even more lacking. There are no big trials done investigating soy and acne. If you surf forums, you will notice that soy is pretty controversial as some claim that soy actually improves their acne condition while others claim that it worsens their acne condition.
Soy milk is made from processed soybeans, which can have estrogen-mimicking effects on the body. That could possibly be the reason for aggravating acne.
In the study by Law et.al, they found that in some cases, an intake of soy products was significantly linked to a lower incidence of acne. This association was noticed in subjects who were yang-predominant, according to traditional Chinese medicine. Yang is associated with heat and acute illness, according to the Alternative Medicine Foundation.
Acne Fighting Food
Again, there is no hard evidence that the food listed below will clear your acne or help in acne prevention. However, I am combining a list of possible acne fighting foods based on scientific evidence. These are healthy foods that are good for your general health, thus, there is no harm in adding them to your diet.
1) Omega-3 fatty acids rich food
Studies show that people who maintain a traditional diet high in omega-3 fatty acids have low rates of acne. Omega-3 fatty acids are known to reduce inflammation.
Your acne might look less red and angry after consuming these foods.
- Fish such as salmon, tuna, trout, mackerel, sardines and herring
- Nuts such as walnuts and butternuts
- Seeds such as flax seeds, chia seeds, sunflower seeds
- Oils such as canola oil, flaxseed oil, soybean oil.
2) Selenium rich food
Researchers found that acne patients have low levels of blood selenium. One other study found that the combination of selenium (400 mcg) and vitamin E(20 mg) led to improvements in acne patients.
Some food rich in selenium are:
Fish such as tuna, halibut, sardines, salmon
Shellfish such as oysters, clams, mussels, scallops
Red meat such as beef, lamb, pork, liver, kidney
Grains such as wheat germ, barley, brown Rice, oats
As described above, researchers found that acne conditions improved with the intake of selenium and vitamin E. Vitamin E food also help in reducing scarring.
Some food rich in vitamin E are:
- Leafy green vegetables such as spinach
- Sunflower seeds
- Shellfish such as shrimp, crayfish, oyster
- Fish such as rainbow trout, swordfish, salmon
4) Vitamin A rich food
Researchers have also found that lower levels of vitamins A and E were found to be associated with the severity of acne. Vitamin A helps regulate the skin cycle and is essential for great skin health. After all, Isotretinoin and Tretinoin – prescribed acne medication, closely resembles the structure of Vitamin A.
Some food rich in vitamin A are:
- Sweet Potato
- Dark leafy green vegetable such as kale, spinach, pak choi
- Fruits such as cantaloupe melon, apricot, prune, peach, mango,papaya
- Bell Peppers
Study has shown that acne patients have lower levels of zinc. They also found that patients with more severe acne had lower serum zinc levels compared to the milder cases. Top up your zinc intake and you might see improvements in your acne.
Some food rich in Zinc are:
- Seafood such as oysters, crab, lobsters
- Red meat such as beef, lamb and pork
- Wheat germ
- Seeds such as pumpkin and squash seeds, sunflower seeds, chiaseeds, flax seeds
- Green leafy vegetables such as spinach, amaranth leaves
- Nuts such as cashew nuts, pine nuts, pecans
Very limited studies have been done on chromium and acne. There was an open label trial conducted and it showed that 400 mcg of chromium improves acne.
Some food rich in Chromium are:
- Whole grain breads and cereals
- Wheat germ
- Brewer’s yeast
- Bran cereal
This is very much still a hypothesis but there is some experimental evidence and clinical anecdotes on how an imbalance of gut bacteria can contribute to skin inflammation. Taking probiotics will help restore the healthy bacteria flora in the gut and possibly help in reducing acne.
Some foods rich in probiotics are:
- live-cultured yogurt, especially homemade
- Miso soup
In summary, find your ’trigger’ food that triggers your acne flares. Drink plenty of water and have a balanced healthy diet.
Making changes to your diet might help but using the right products is equally important! Use Skinlycious products to clear your acne and to maintain acne-free skin.
