Dairy-Free Diet

Whole Milk

Dairy-Free Diets exclude the consumption of milk and all milk-based products, such as yogurt and cheese. The natural function of milk is to provide the nutrition necessary for the growth and development of young offspring. All female mammals produce milk and the name “Mammal” derives from “Mammary”, which is the gland responsible for milk production. Humans, cows, dogs, cats and mice are all mammals. Milk is a rich nutritional source that contains abundant concentrations of essential compounds, such as proteins, sugars, vitamins and minerals.

Unfortunately for some adult humans, consumption of milk and other dairy products can cause unpleasant side effects. Some people are lactose-intolerant, which means that they are not able to properly digest lactose (a sugar naturally found in milk). Dairy-Free Diets are commonly prescribed for people who are lactose-intolerant. Consumption of dairy products can also cause allergic or auto-immune reactions in some people. Although this process is not entirely understood, certain milk proteins (eg. Casein) are known to cause allergic reactions in susceptible individuals.

Milk consumption is one of the dietary factors that has been most frequently correlated with acne symptoms. There have been numerous scientific studies to investigate the relationship between dairy intake and acne. Although there is some disagreement between studies, many of the studies have found that high dairy consumption was associated with more acne symptoms.

There are several possible reasons why dairy consumption might cause more frequent or severe acne outbreaks. One possibility is that some molecules found in milk might trigger hormonal changes that can contribute to acne. Another possibility is that the hormones in milk (milk naturally contains hormones, most milk products no longer contain synthetic hormones, such as bGH Bovine Growth Hormone) directly affect the hormonal balance in the body. A third possibility is that milk can contain high levels of specific molecules (eg. Iodine) that can trigger acne in high doses. Overall, the causative relationship between dairy consumption and acne symptoms remains poorly defined, but warrants deeper investigation.
