Do Dairy Foods Cause Inflammation?

When we consume a balanced diet including vegetable, meat and poultry, fish, dairy, fruit and whole grains we absorb an abundance of nutrients. These nutrients including vitamins, minerals, phytonutrients, carbohydrate, fat, fibre and protein work together in our body to help us to achieve peak health and performance.

Dairy foods have long been celebrated for their role in developing and maintaining peak bone mass because of their rich calcium, phosphorus and other mineral content. More recently, researchers have noted the beneficial role of whey protein (found in dairy foods) for maintaining and increasing lean muscles mass, as well as improved function and mobility in older adults aged >65 years (1).

Historically, dairy has been incorrectly labelled as 'pro-inflammatory' and associated with adverse health issues including, weight gain, type 2 diabetes and cardiovascular disease. However, recent research has, in fact, found that dairy can actually be beneficial for body composition and reducing inflammation (2,3,4).

Various sources have suggested that high-fat dairy foods may be linked to a state of chronic inflammation, which leads to an increased risk of cardiovascular disease and subsequent contribution to overweight and obesity (5). Furthermore, dairy foods including milk, cheese and yoghurt have been labelled as ‘inflammation causing’ or ‘mucus producing’ - both of which lack substantial evidence.

Recent scientific opinion now believes the aforementioned adverse health effect, originally associated with saturated fat are actually due to other factors (6). Research has found that saturated fat within dairy foods does not actually contribute to systematic inflammation, cardiovascular disease, raised LDL, atherosclerosis and high blood pressure (2,5,7). Drouin and colleagues performed a comprehensive review of current randomised controlled trials, investigating the effects of full-fat and low-fat dairy products and their impact on markers of health. They found no significant association between consuming full-fat dairy products and increased LDL cholesterol, or markers of inflammation, compared with low-fat dairy in healthy adults (7). In this same study, individuals who ate cheese had slightly lower LDL concentrations in the blood, suggesting the bioactive peptides, minerals and fat found in cheese could be providing protective effects (7).  

Low or full-fat dairy has also been found to positively improve blood pressure in healthy individuals and individuals with hypertension, subsequently reducing inflammation, most likely due to the unique combination of protein, potassium, phosphorus, calcium and other micronutrients working simultaneously or independently (9,11). As recent research shows, full-fat dairy is not associated with the adverse health outcomes in healthy or at risk individuals as previously thought. 

In addition to the mounting evidence supporting high-fat dairy food, another rapidly growing area of interest is the association between fermentable foods and gut health. Bordoni and colleagues performed a systematic review of over 52 clinical trials of dairy products and inflammation, finding both low and high-fat dairy foods has positive anti-inflammatory effects due to the polyunsaturated fat and other dairy nutrients. In particular, fermented dairy products such as yoghurt, lead to significant anti-inflammatory actions, especially in those with cardiovascular disease (2). More research is needed to ascertain the exact reasons underlying such results; however, the role of lactic acid bacteria and bifidobacteria is one of the proposed mechanisms reducing inflammation and supporting optimal gut health and immunity (2). Consideration to the role of bioactive proteins and glycans that interact with our gut bacteria may also promote anti-inflammatory activity (2).

It is without question that people experiencing a medically diagnosed allergic reaction to dairy protein should see appropriate dairy alternatives (2). Those experiencing gastrointestinal upset associated with poor tolerance or sensitivity to lactose, can still consume small amounts of dairy, particular if spread over the day and eaten as part of a whole meal.

Further research into the beneficial role of dairy on inflammation is welcome, however, at this point in time, there is no evidence to suggest that dairy products cause systemic inflammation, weight gain or associated metabolic diseases as previously hypothesised. Individuals should enjoy dairy with the confidence that dairy foods are not harmful, and are in fact beneficial to health when eaten as part of a well-balanced, varied and minimally processed style of eating across all stages of the lifespan.
