A recent review of over 2,500 studies challenges the long-held belief that cheese is bad for heart health. Researchers found that eating about 40 grams of cheese per day — roughly the size of a small matchbox — is linked to a lower risk of cardiovascular disease. This protective effect is thought to come from the unique way cheese’s ingredients work together. The combination of calcium, vitamin K2, and lactic bacteria from fermentation may help reduce inflammation and support heart health. Fermented cheeses like Comté or Camembert seem to offer the most benefits, while ultra-processed cheeses or those eaten in large amounts do not. For decades, cheese was considered unhealthy because of its saturated fats, salt, and calories. These concerns were reinforced by dietary guidelines from the 1980s, which relied on assumptions rather than long-term scientific evidence. The problem was that cheese was often compared directly to other animal fats, without considering its unique structure or the presence of beneficial nutrients. This led to an oversimplified view of cheese as a harmful food, even though it contains important vitamins and minerals. Interestingly, countries with the highest cheese consumption, such as those in Western Europe, tend to have some of the lowest rates of cardiovascular disease. This paradox prompted scientists to dig deeper. After analyzing a vast amount of data, they found that people who eat around 40 grams of cheese daily — close to the average European consumption — have a significantly lower risk of heart disease. Some studies with over 30,000 participants found a 10% drop in risk, while larger analyses covering nearly 1.8 million people showed an 8% reduction in overall cardiovascular risk. Eating an extra 30 grams of cheese daily was linked to a 3% further decrease in risk. The benefits of cheese go beyond heart health. Each additional 30-gram serving per day was also associated with a 2% lower risk of death from any cause. These findings challenge the idea that saturated fats are always bad for the heart. Instead, scientists suggest that the structure of cheese — known as a food matrix — plays a key role. In cheese, fats are combined with proteins, calcium, and compounds from fermentation in a way that may help the body process them more effectively, reducing their negative impact. Cheese is not just a source of fats; it also provides calcium, protein, vitamin B12, and other essential nutrients. It can supply up to 18% of an adult’s daily calcium needs, which is important not only for bones but also for heart function. It also contains vitamin K2, which supports both bone and cardiovascular health. Additionally, the lactic bacteria found in fermented cheeses like Camembert or Roquefort may help maintain a healthy balance of gut bacteria, which in turn influences overall inflammation — a known contributor to heart disease. While cheese can be beneficial, the type and amount matter. Fermented cheeses and low-fat dairy products seem to offer the most protection against heart disease and strokes. Studies have found that people who regularly eat these cheeses have a lower risk of heart attacks and strokes. However, ultra-processed cheeses or those consumed in excess, especially within an unbalanced diet, do not offer the same benefits. Overall, cheese appears to be more nuanced in its effects than previously thought. Eating around 40 grams a day seems to be the optimal amount, and the findings encourage a more balanced view of food, considering not just what is eaten, but how and in what context.
