THE FRENCH POPULATION consumes as much saturated fat and cholesterol as populations in other Western nations, but France has the least prevalence of cardiovascular disease among studied Western nations (Artaud-Wild et al., 1993). To explain this phenomenon, called the French paradox, researchers have investigated cardioprotective properties of resveratrol in red wine that is consumed in large quantities by the French, but no epidemiological studies support the red wine hypothesis throughout Europe (Opie & Lecour, 2007; Semba et al., 2014). The search to identify additional cardioprotective factors in the French diet that may apply to other countries has recently examined other food items like traditional cheeses (Petyaev & Bashmako, 2012). Cheese and dairy products that are high in saturated fat and cholesterol are often consumed raw in the traditional French diet, without pasteurization. This article presents a brief literature review to explore whether cardioprotective effects exist in raw versus pasteurized dairy consumption. This article also introduces a hypothesis which proposes that raw dairy consumption is associated with the French paradox, and the article recommends further epidemiological studies to investigate a possible association in other countries.

Cholesterol Oxidation Products

Epidemiologists first identified the French paradox in the 1980s when the French population’s fat intake was just under 40% of calories (Ferriere, 2003). Since that time, efforts have been made to reduce saturated fat intake in Western nations in order to reduce coronary heart disease rates. However, several meta-analyses that specifically focused on dietary saturated fat intake found no association with saturated fat and cardiovascular disease (Chowdhury et al., 2014; Siri-Tarin et al., 2010). Based on these findings, dietary cholesterol may be a more likely causative factor that increases risk for cardiovascular disease. 

Research has shown that cholesterol undergoes chemical changes in thermally treated animal-based food like dairy products, which generates harmful cholesterol oxidation products or COPs (Hur, Park, & Joo, 2007). These oxidized cholesterol products have been found to damage arteries in the cardiovascular system much more than natural, unprocessed cholesterol. The most common oxidized cholesterol product found in heat-treated animal-based food is 7-ketocholesterol. Total COPs may account for between 1–10% or more of the cholesterol in heat-treated or processed animal-based food. Because saturated fat is naturally present in animal-based foods, and because these foods contain artery-damaging COPs when heated, this could explain why saturated fat has been mistakenly linked with causing cardiovascular disease. In other words, saturated fat in heated animal-based food may be only an indicator of dietary cholesterol and harmful COPs. Because saturated fat consists of single carbon bonds only and no double bonds, it is not as susceptible to oxidation when heated.

The Masai

The French paradox is unique among modern Western nations, but it is not unique among primitive tribes. For example, the Masai tribe of Kenya, Africa, consumes large amounts of Kule naoto, a fermented raw milk which provides the Masai’s main dietary source of nutrients (Mathara et al., 2008). Yet, like the French, the Masai people have low prevalence of cardiovascular disease despite their high intake of dietary cholesterol and saturated fat (Mann et al., 1964). However, unlike the French, the Masai do not include much grain or fruit in their diet, and therefore the Masai people consume little or no red wine, preferring instead to drink the blood of their cattle. And while the rural Masai people are very physically active, by contrast, contemporary French lifestyles incorporate many labor-saving conveniences. Therefore, it appears that unheated raw dairy consumption is one of the few common dietary and lifestyle factors that the Masai people share with the French population.

Traditional Raw Cheese

Researchers examined consumer attitudes toward purchasing traditional cheeses in France and in Norway, and it was found that most French people preferred traditional unpasteurized cheese while most Norwegians preferred pasteurized cheese (Almli et al., 2011). Interestingly, Scandinavian countries have a higher prevalence of cardiovascular disease than France, which is consistent with the French paradox (Artaud-Wild et al., 1993). Most French people regularly eat approximately 400 types of cheeses among over 1,000 cheeses produced throughout various regions of the country. The French spend 6.8% of their food budget on cheese and consume 24.6 kilograms (over 54 pounds) of cheese annually.  Raw cheeses account for 10% of the 1.9 million tons of annual cheese production in France (Almli et al., 2011), Therefore, in combination with other raw dairy products, it is hypothesized that raw cheese consumption is associated with the French paradox.

Risks and Benefits of Raw Milk

The French preference for raw milk consumption is reflected in the popular distribution of raw-milk vending machines throughout France, as seen in the illustration below.

The World Health Organization Collaborating Centre at the University of Franche-Comté summarized the health risks and benefits of consuming unpasteurized dairy products (Vuitton, n.d.). While acknowledging the potential for foodborne illnesses in contaminated raw dairy, cases of contamination are rare in commercially available raw dairy products in France due to strict production processes and managed microbiological control procedures to keep the product safe. Also, pasteurization does not prevent secondary contamination that may occur during processing, packaging and storage. In other words, either dairy products are clean and safe to consume or they are not, regardless if they are raw or pasteurized. Raw milk is also claimed to have beneficial effects on intestinal flora by providing probiotic organisms (Baruzzi et al., 2011).


Cheese and wine are equally important cultural icons in France (Roberts & Micken, 1996), and neither food is traditionally thermally treated. While red wine contributes high levels of vital antioxidants that may contribute to the low rate of cardiovascular disease in the French paradox, a hypothesis for an additional factor proposes that raw dairy contributes a lower level of pro-oxidants or COPs which may be equally if not more important in accounting for the country’s lower rate of cardiovascular disease. Further research should rigorously explore the relationship between consumption of raw and pasteurized dairy and prevalence of cardiovascular disease in France and in other countries.

An epidemiological study can only investigate associations, however, and is not sufficient to establish a causative relationship between cardiovascular disease risk and pasteurized dairy consumption. In the event that a significant association is discovered in the proposed epidemiological study, and since clinical studies are also lacking to test the cardiovascular risk of consuming pasteurized dairy compared to raw dairy, it is recommended that dietary clinical trials test for indicators of cardiovascular disease in subjects consuming raw versus pasteurized dairy, perhaps with and without red wine. Furthermore, if a causative relationship is established between pasteurized dairy and increased risk for cardiovascular disease, this could lead to even more detailed research examining the health implications of thermally-treated dairy processing.


In conclusion, there appears to be sufficient evidence from peer-reviewed research literature to propose a hypothesis that raw dairy products are associated with lower rates of cardiovascular disease in the French paradox. Compared to thermally-treated dairy consumed in other Western nations, raw dairy in France contains fewer cholesterol oxidation products that harm arteries in the cardiovascular system. Future epidemiological and clinical research should explore this association.
