Welcome to a special guest post by UF student Elena Smith,
a graduate student and dietetic intern in Nutritional Sciences.
Do you have acne? Have you ever wondered whether the food you eat is related to your acne? Below are a few common statements about acne and diet, and their respective summaries of the research that has been conducted for each.
1. “Dairy causes acne”
There is conflicting evidence on whether dairy causes acne or not.1,2,3 There are many factors to consider when drawing a conclusion on whether dairy will influence acne severity. Dairy is only one component of the diet. Someone with acne should also consider multiple aspects of one’s lifestyle including: overall diet pattern, e.g. eating more whole foods over processed foods, is the face touched often with unwashed hands, is the pillow case laundered adequately, is sufficient water consumed, etc. Until more convincing research is published, consuming dairy may or may not be acne provoking. However if an individual decides to avoid or limit dairy, they should still consume a fortified dairy alternative with added amounts of vitamin D and calcium like cashew, almond, or oat milk, or consume foods packed with calcium (i.e. almonds, kale, broccoli, salmon, etc.) to ensure nutritional adequacy.
2. “Red meat causes acne”
To date there has not been an exact causal association found between red meat and acne. Though, there has been research conducted on whether the Western diet is correlated with acne or not. The Western diet includes large amounts of red meat, dairy products, refined grains, and sugar. Some scientific evidence has suggested that the Western diet positively correlates to acne, along with obesity, diabetes, heart disease, and cancer.4 If an individual decides to not consume red meat, be sure to eat enough other protein sources such as chicken, turkey, salmon, beans, nuts, and/or lentils to meet adequate protein needs.
3. “Eating a low glycemic load diet will help minimize acne”
Researchers (including registered dietitians and dermatologists) have been working to identify if a low glycemic load diet would help reduce acne in individuals.5,6,7 New research suggests that a low glycemic load diet may possibly induce lower circulating insulin-like growth factor (IGF)-1 levels (IGF-1 a growth hormone), which could possibly decrease acne severity. Intervention studies suggest that hyperinsulinemia (from a high glycemic load diet) could induce higher circulating IGF-1 levels and play a role in the increase of acne severity.8,9 At this time research is not conclusive and more evidence is needed to conclude that a lower glycemic load diet can reduce acne.
Regardless of the food, it’s hard to pinpoint what specifically will trigger acne. Eating one single food or removing one single food from your diet will likely not alleviate your acne,10 but rather multiple factors would affect one being prone to acne such as genetics, your overall eating pattern, sleep pattern, hygiene, etc. More quality research is needed to evaluate the relationship between diet and acne.
1. Eat enough colorful fruits and vegetables
MyPlate recommends about 1 ½ – 2 cups of fruit per day and 2 – 3 cups of vegetables per day. Add a variety of colorful fruits and vegetables.
2. Hydrate, hydrate, hydrate!
Regardless of whether someone has acne or not, your body will thank you for drinking enough water.
During college, it may seem hard to get 7-9 hours of sleep every night, but important processes happen in your body while you sleep. Try getting more sleep and note any changes to your skin condition.
5. Taking time for yourself, and with others!
If you’re a college student, try setting up college as a 9-5pm job, then after 5pm set that time aside to invite a friend over for dinner, call a family member, play some pick-up soccer, and/or go to the gym!
6. Visit a dermatologist
It may be time for you to see a dermatologist for an expert opinion.
