There are many factors that can influence skin health, and it is important to remember that everyone's skin is different. While there is limited scientific evidence to support the claim that cheese is bad for the skin, some people have reported experiencing skin improvements after cutting down on dairy products, including cheese. Some experts suggest that the hormones present in dairy products may be the reason for skin issues, while others point to insulin levels and blood sugar spikes as potential triggers for acne. It is worth noting that individual experiences may vary, and it is always recommended to consult a dermatologist or a healthcare professional for personalized advice.

What You'll Learn
Dairy and acne
Dairy products have been linked to acne, but the evidence is limited and conflicting. Some people report that their acne improved after cutting out dairy, while others find that only certain types of dairy, such as cow's milk, affect their skin.
A 2019 study found a link between overall milk consumption and acne, with skimmed milk having the most negative impact on the skin. However, other studies have failed to find a connection between acne and drinking whole milk. Fermented dairy products like yoghurt and cheese have not been found to increase the risk of acne and may even have benefits for heart and bone health.
The hormones present in milk, such as testosterone and insulin-like growth factor-1 (IGF-1), are thought to be the main culprits behind dairy-induced acne. These hormones can stimulate oil glands in the skin, creating an environment conducive to acne development. Additionally, milk contains casein and whey protein, which can raise IGF-1 levels, further influencing acne formation.
While the relationship between dairy and acne is not yet fully understood, it is clear that individual factors play a significant role. Keeping a food diary can help identify personal triggers, as acne is a condition influenced by internal reactions within the body. Working with a dermatologist or dietitian to ensure a balanced diet while exploring potential dairy triggers is recommended.
In summary, while dairy may be a contributing factor to acne for some individuals, the impact varies depending on the type of dairy and individual responses. Further scientific studies are needed to definitively establish the link between dairy consumption and acne.

Insulin levels and acne
While there is limited research on the direct link between cheese and skin problems, some studies have found a correlation between acne and insulin levels.
Acne vulgaris is a chronic inflammatory disease of the skin that usually affects adolescents. The aetiology and severity of acne may be influenced by hyperinsulinemia and insulin resistance. Hyperinsulinemia refers to high levels of insulin in the blood, which can be caused by a high-glycemic diet. Insulin resistance occurs when the body's cells become less sensitive to insulin, resulting in the pancreas having to release even more insulin to bring down blood sugar levels. This can lead to a hormone cascade that stimulates increased levels of free IGF1, a potent mitogen that promotes acne by increasing keratin production.
Several studies have found a correlation between high-glycemic diets and acne. High-glycemic foods cause a rapid increase in blood sugar levels, leading to a corresponding increase in insulin. This can trigger a stress response in the adrenal glands, causing them to release androgens, which are associated with acne development. In addition, high insulin levels can decrease IGF-1 binding proteins, leading to an increase in free IGF1, which further promotes acne.
Some researchers have proposed that acne may be strongly associated with insulin resistance, with one study finding that 81% of acne patients had insulin resistance based on their C-peptide levels, compared to only 18.75% in the control group. However, another study published in a dermatology journal found no association between acne, insulin levels, and glycemic load, indicating that more research is needed to fully understand the relationship between insulin and acne.
It is important to note that while high-glycemic diets and insulin resistance may play a role in acne, other factors, such as genetics, hormones, and skin care habits, also contribute to the development of acne. A well-rounded approach to treating acne should consider all of these factors and may include dietary modifications, medication, and personalized therapies.

Blood sugar and inflammation
Blood sugar and insulin levels have been linked to skin health. High blood sugar levels have been associated with premature ageing and acne. This is because high blood sugar triggers the body to produce more insulin, a hormone that breaks down blood sugar. Insulin may also play a role in acne, although this is not yet confirmed. Eating foods with a low glycemic index (GI) can help to keep blood sugar levels steady, which may be beneficial for skin health.
Cheese is a dairy product that contains milk sugar, or lactose. The bacteria in cheese break lactose down into glucose and galactose. While cheese contains small amounts of carbohydrates, it is high in protein and fat. As such, cheese is generally considered to have a low GI and is unlikely to cause large spikes in blood sugar levels. However, some types of cheese contain more carbohydrates than others, so it is important to check the nutritional label.
Cheese also contains whey protein, which can stimulate insulin secretion and prevent blood glucose spikes. However, cheese is high in saturated fat, which can impact cholesterol and blood pressure. Excess saturated fat can also affect insulin sensitivity, increasing the risk of diabetes. Therefore, while cheese may not directly cause large spikes in blood sugar, it can still impact blood sugar regulation in the body.
For people with diabetes, cheese can be consumed in moderation as part of a balanced diet. Lower-fat cheeses are recommended to reduce the risk of associated health issues. Swiss cheese, for example, is a low-calorie option with low sodium and fat content. Other low-fat cheeses include cottage cheese, ricotta cheese, parmesan, feta, and goat cheese. These cheeses also contain beneficial bacteria that support gut health and improve digestion.

Hormones in milk
Milk and dairy products, such as cheese, butter, and yoghurt, are important components of the human diet, especially in Western culture. Dairy foods are a source of hormones, which are essential for infant growth and immunity. However, the presence of certain hormones in dairy products has raised concerns about their potential impact on human health, particularly the initiation and development of specific cancers.
Cow's milk, a significant source of milk consumption for humans, contains hormones such as prolactin, steroids (including estrogens, progesterone, corticoids, and androgens), insulin-like growth factor-1 (IGF-1), and local hormones like prostaglandins. The highest concentration of prolactin (PRL) is found in the milk of cows and women during the first few days after giving birth. While PRL levels in cow's milk decrease over time, they are influenced by the season, with the highest levels observed in July and the lowest in November.
The presence of steroid hormones in dairy products has been suggested as a possible risk factor for various cancers in humans, including cancers of the testes, prostate, and breast. These hormones may play a role in initiating and provoking these cancers. Additionally, the estrogen content in cow's milk has been a particular concern, as natural estrogens are significantly more potent than their environmental counterparts, such as those found in pesticides. Dairy products are estimated to contribute between 60% and 80% of the estrogens consumed in the human diet.
The impact of hormones in milk on skin health has also been a topic of interest. Skin is sensitive to hormonal changes, and abnormal hormonal activity is associated with skin issues like acne. Milk stimulates hormonal activity, and the hormones it contains may affect the skin. Some studies have found a link between milk consumption and acne, while others have not observed a direct association between acne and drinking whole milk. However, it is important to note that individual tolerance varies, and not everyone experiences adverse skin reactions to dairy.
While the relationship between hormones in milk and skin health requires further investigation, some experts suggest consulting a dermatologist to discuss dairy intake if acne is a concern.
