Dietary choices may affect the health of your skin, and certain foods may raise your blood sugar levels, causing the body to release the hormone insulin-like growth factor 1 (IGF-1). High levels of IGF-1 may cause the oil glands in your skin to produce more sebum, increasing your risk of acne and skin inflammation. Foods with a high glycemic index (GI) such as candy bars, white bread, white rice, and cake can cause sharp, sudden rises in blood sugar levels. Cutting down on these foods and replacing them with low-GI alternatives like lentils and whole grain bread may help to reduce acne. In addition, consuming more omega-3 fatty acids, found in fish, can lower inflammation and may help to keep acne at bay.

What You'll Learn
Dairy products
Dairy is often touted as a necessary part of a healthy diet, but it is possible to cut it out without compromising your nutrient intake. Milk and cheese are good sources of protein and calcium, but these nutrients can be obtained from other foods. For example, calcium can be found in leafy greens, tofu, and calcium-fortified orange juice.
Some people have reported significant improvements in their skin after cutting out dairy. One person reported that their lifelong battle with cystic acne was cured within a month of giving up dairy. Another source reported that their acne improved after three weeks of a dairy-free diet.
It is important to note that dietary changes may not be a cure-all for acne, and individual results may vary. While cutting out dairy may help improve your skin, it is not a substitute for a balanced and varied diet, careful skincare, and other treatments. If you are considering making dietary changes to address acne, it is recommended to speak with a healthcare professional to ensure you are meeting your nutritional needs.

Sugar and high-GI foods
High-GI foods have a GI score of over 55. This score is indicative of worse glycemic control and higher insulin and insulin-like growth factor 1 (IGF-1) levels. IGF-1 increases the expression of inflammatory biomarkers and sebum production in cultured sebocytes, leading to acne. A low-GL diet focuses on foods with a lower glycemic index, such as lentils, which lead to a slow and steady rise in blood sugar levels.
To cut down on sugar and high-GI foods, it is recommended to reduce your consumption of sweets such as cookies, cupcakes, and candy bars. It is also important to be mindful of less obvious sources of sugar, such as breakfast cereal and bottled iced tea. Additionally, other high-GI foods that can spike your blood sugar include white bread, white rice, and cake.
While there is no definitive link between diet and acne, dietary choices may affect skin health. Research suggests that a high-fiber diet can help control blood sugar, which is beneficial for acne management. Furthermore, foods rich in antioxidants, such as blueberries, tomatoes, and apricots, can help improve skin health due to their anti-inflammatory properties.
It is worth noting that the Western diet, characterized by high sugar and glycemic content, has been linked to greater inflammation levels, which could contribute to chronic acne problems. Therefore, reducing your consumption of sugar and high-GI foods may help improve acne and overall skin health.

Omega-3 fatty acids
Inflammation plays a significant role in the development of acne. It involves the overproduction of sebum, an oily substance produced by the skin's sebaceous glands, which can lead to clogged pores and the proliferation of acne-causing bacteria. Omega-3 fatty acids, particularly eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), found primarily in fish and fish oil, have been shown to possess anti-inflammatory properties.
A small study examined the link between blood levels of EPA and acne. Participants with acne had lower blood levels of EPA and higher levels of certain inflammatory markers compared to those without acne. This suggests that EPA may play a role in reducing acne-related inflammation. Another randomised controlled trial found that taking 2,000 mg of EPA and DHA supplements daily for 10 weeks significantly reduced both inflammatory and non-inflammatory acne lesions.
However, it is important to note that not all studies have shown clear benefits. One study observed no significant changes in acne severity or inflammatory lesions when participants took a daily fish oil supplement containing EPA for 12 weeks. While the potential benefits of omega-3 fatty acids for acne are promising, more research is needed to confirm their effectiveness.
In addition to their potential anti-inflammatory effects, omega-3 fatty acids may also help reduce acne by lowering the production of insulin-like growth factor-1 (IGF-1). IGF-1 is a hormone that can stimulate sebum production and increase the risk of acne and skin inflammation. By reducing IGF-1 levels, omega-3 fatty acids may help regulate sebum production and alleviate acne severity.
Overall, while dietary changes alone may not be sufficient to clear acne, incorporating omega-3 fatty acids into your diet or taking supplements may be a worthwhile strategy to explore. It is always recommended to consult with a dermatologist or healthcare professional to determine the most suitable treatment approach for your specific needs.

Anti-inflammatory foods
While there is no conclusive evidence that food alone can cause or cure acne, dietary choices may affect skin health. Certain foods may cause spikes in blood sugar, leading to increased sebum production and a higher risk of acne and skin inflammation.
To combat this, it is recommended to cut down on high-glycemic foods, such as candy bars, soda, white bread, white rice, and cake. Instead, opt for low-glycemic alternatives like lentils and whole grain bread.
In addition to a low-glycemic diet, incorporating anti-inflammatory foods may help improve acne. Here are some dietary suggestions to consider:
Omega-3 Fatty Acids: Omega-3 Fatty Acids found in fish, such as salmon, have been shown to provide anti-inflammatory benefits, helping to maintain a clear complexion. Plant-based sources of omega-3s include nuts and seeds.
Antioxidants: Fruits and vegetables are naturally rich in antioxidants, which have anti-inflammatory properties. Specifically, dark-pigmented fruits and vegetables like pomegranates, beetroot, and berries are recommended.
Zinc: Zinc is a nutrient that may help kill acne-causing bacteria and reduce inflammation. Good sources of zinc include nuts, such as almonds and Brazil nuts. However, it is important not to exceed the recommended daily intake of 40 milligrams for adults.
Vitamin D: Research suggests that vitamin D deficiency may be linked to acne due to its anti-inflammatory properties. Increasing your vitamin D intake through supplements or spending time in the sun may help improve acne lesions.
Probiotics: Probiotics, found in fermented foods or supplements, may help reduce acne and improve the absorption of oral acne medications.
Herbs and Spices: Incorporating anti-inflammatory herbs and spices like turmeric, cinnamon, black pepper, parsley, garlic, ginger, and cayenne may also help reduce inflammation associated with acne.
While making dietary changes, it is important to be mindful that everyone's skin is unique, and individual results may vary. For personalized recommendations, it is always best to consult a dermatologist or a healthcare professional.

Zinc
The form of zinc you take for acne treatment depends on several factors, including the severity of your acne, your skin type, and your current dietary habits. Oral zinc supplements are available and can be prescribed by doctors. However, they can cause side effects like nausea and vomiting, and may interact with certain prescription medications. Topical zinc treatments, such as pastes, gels, or creams, are also available and can be applied directly to the skin. While they carry fewer side effects, they are generally considered less effective than oral supplements.
You can also increase your zinc intake by altering your diet. Oysters are the food with the highest zinc content per serving. Other good sources of zinc include certain meats, as the body finds it easier to absorb zinc from animal-based foods. Some plant-based foods are also good sources of zinc, but the body may absorb less zinc from them due to the presence of phytates.
