Diet is believed to play a role in acne development, with certain foods potentially triggering acne outbreaks. A low-glycemic diet that eliminates spikes in blood sugar may help reduce acne, as high blood sugar can cause inflammation and excess sebum production, both of which are linked to acne. Additionally, dairy products, particularly cow's milk, have been associated with increased acne severity, possibly due to the hormones present in milk. However, the link between diet and acne is complex and controversial, with some studies failing to find a definitive connection. While dietary changes may not be a guaranteed solution for clear skin, paying attention to one's diet and identifying potential trigger foods can help reduce the chances of acne outbreaks.

What You'll Learn
Dairy products and milk
One theory suggests that dairy cows are treated with artificial hormones that can affect milk supply. Consuming these hormones may disrupt the body's natural hormone balance, triggering acne breakouts. Another theory posits that the growth hormones naturally present in milk can aggravate acne. Additionally, when combined with refined foods and processed sugars, dairy products may disrupt insulin levels, making the skin more prone to acne.
Some studies have specifically implicated skim milk as the most likely acne trigger among dairy products. A 2015 study from the Journal of the American Academy of Dermatology found a positive association between the consumption of low-fat and skim milk and acne. Similarly, a 2010 study of 5,000 Chinese teenagers and young adults linked high-fat diets, including dairy products and ice cream, to a 43% increased risk of developing acne.
While the link between dairy and acne is not yet fully understood, it is clear that dairy products and milk can influence acne development, particularly in teenagers and young adults. Further research is needed to establish a definitive causal relationship and understand the underlying mechanisms.

High-glycemic foods
According to some studies, a low-glycemic diet that eliminates spikes in blood sugar may help to reduce acne. Low-glycemic diets are associated with reduced acne severity and improved inflammation. This is because low-GI foods have a minimal impact on blood sugar, causing only a moderate or small increase. Examples of low-GI foods include most vegetables, dark leafy greens, cauliflower, and most dairy without added sweeteners.
While there is evidence to suggest that high-glycemic foods can contribute to acne, the link between diet and acne is still controversial. More research is needed to fully understand the relationship between high-glycemic diets and acne development. However, it is important to note that diet is not the only factor contributing to acne, and other factors such as hormones, blocked pores, and bacteria also play a role.

Refined carbohydrates
High glycemic index foods are typically processed foods high in white flour, such as white bread, pasta, crackers, and white rice. Sugary foods such as soda, juice, and candy bars are also on the list, as are fried foods like French fries. One study found that frequent consumption of foods high in sugar or fat was associated with 54% higher odds of having acne, while sugary beverages were linked to 18% higher odds.
The Mediterranean diet is recommended as an alternative to a diet rich in refined carbohydrates. This diet includes more fish, fresh fruits and vegetables (fiber), olive oil instead of other fats, and whole grains.
While the research on this topic is promising, more is needed to fully understand how refined carbohydrates contribute to acne.

Insulin resistance
While the link between diet and acne has been controversial, recent studies have shown that diet can play a significant role in acne development. Insulin resistance may be caused by a diet high in refined carbohydrates, which are absorbed quickly into the bloodstream, rapidly raising blood sugar levels. This, in turn, increases insulin levels as the insulin works to shuttle blood sugars out of the bloodstream and into cells.
Consuming foods that cause blood sugar to rise quickly, such as white bread, pastries, and sugary drinks, may worsen acne. A low-glycemic diet, which does not cause spikes in blood sugar or insulin levels, is associated with reduced acne severity. However, it is important to note that some studies have found no correlation between IR and acne development, and more research is needed to understand the relationship fully.
To test for insulin resistance, you can check your blood glucose levels before and after consuming sugary drinks for up to two hours. If your insulin is working well, your blood glucose levels will return to normal within two hours. Another test is to check your HDL (good cholesterol) and triglyceride levels. An HDL level under 60 and triglycerides over 100 could indicate insulin resistance.
While the exact mechanism is not fully understood, IR may be a factor in the resistance to standard acne treatments. Treatment with metformin has been shown to be effective in reducing insulin resistance and improving acne.

Diet and Inflammation
A diet high in sugar can cause inflammation, which is a factor in the development of acne. Sugar can also damage collagen and elastin, two proteins that keep the skin smooth and elastic. A diet high in sugar can also lead to glycation, a process in which sugar molecules bind to and damage proteins. Glycation can cause inflammation and skin ageing.
Foods that Cause Inflammation
- Processed meats: bacon, hot dogs, and sausages are all high in "bad" fats and can cause inflammation in the body.
- Fried foods: French fries, fried chicken, and doughnuts are all high in "bad" fats and can cause inflammation in the body.
- Dairy products: milk, cheese, and ice cream are all high in "bad" fats and can cause inflammation in the body.
- Sweets: cakes, cookies, and candies are all high in "bad" fats and can cause inflammation in the body.
- Chips: potato chips, tortilla chips, and corn chips are all high in "bad" fats and can cause inflammation in the body.
Other Inflammatory Foods
- Refined carbohydrates: white bread, pastries, cookies, crackers, and cakes. The mindless eating of refined carbs causes a spike in blood sugar, which then causes a spike in insulin. Insulin is a hormone that promotes the growth of skin cells and the production of sebum, which can clog pores and lead to acne.
- Dairy: Dairy products contain hormones that can trigger acne.
Anti-Inflammatory Diets
Some diets are associated with lower insulin levels, which could benefit acne. These include the Paleolithic and Mediterranean diets. A Mediterranean diet is rich in fruits, vegetables, whole grains, legumes, fish, and olive oil and low in dairy and saturated fats. It has been linked to reduced acne severity.
A low-glycemic diet may also reduce acne because it eliminates spikes in blood sugar, which can cause inflammation throughout the body.

Frequently asked questions
Acne is thought to develop due to a combination of factors: the production of too much oil in the skin, clogged skin pores, bacteria in the skin, and inflammation.
Many factors contribute to the development of acne, including sebum and keratin production, acne-causing bacteria, hormones, blocked pores, and inflammation. While diet may not be the sole reason for acne, it can influence it to some degree.
Foods that cause your blood sugar to rise quickly, such as white bread and fries, may worsen acne. Dairy products, especially cow's milk, have also been linked to acne.
A low-glycemic diet may help reduce acne as it eliminates spikes in your blood sugar. Almonds, peanuts, and Brazil nuts are good sources of antioxidants and zinc, which can help protect your skin cells from damage and infection.
