Vitamin K₂ (menaquinone) concentrations were measured in a wide range of cheeses and the effects of fat content, ripening and origin of the cheeses were investigated. Moreover, the menaquinone content of cheese was compared with that of other foods known to contain vitamin K₂. It was found that cheese and curd are the most important sources of long-chain menaquinones in the Western diet and, in general, hard cheeses are richer in menaquinones than soft cheeses. However, the actual menaquinone content varies substantially and is dependent on the type of cheese, the time of ripening, the fat content and the geographic area where the cheeses are produced. Given the fact that poor vitamin K status has been mentioned as a risk factor for cardiovascular disease and mortality, while there is no clear evidence for adverse cardiovascular effects of dairy fats, cheese should be considered as a recommendable component in a heart-healthy diet.
维生素 K₂（甲萘醌）的浓度在各种奶酪中进行了测量，并研究了脂肪含量、成熟度和奶酪来源的影响。此外，还比较了奶酪中的甲萘醌含量与其他已知含有维生素 K₂的食物。结果发现，奶酪和凝乳是西方饮食中长链甲萘醌的最重要来源，而且一般来说，硬奶酪比软奶酪含有更丰富的甲萘醌。然而，实际的甲萘醌含量差异很大，取决于奶酪的类型、成熟时间、脂肪含量以及奶酪生产的地理位置。鉴于维生素 K 状态不佳被认为是心血管疾病和死亡率的一个风险因素，而乳制品脂肪对心血管没有明显的不良影响，因此奶酪应该被认为是心脏健康饮食中可推荐的成分。
