Cheese is a dairy product that contains lipids. Lipids are present in cheese at levels above 20%. The type of lipids found in cheese include triacylgylcerols, complex phospholipids, and fatty acids. The consumption of cheese has been found to have an effect on blood lipids and lipoproteins in healthy adults.

What You'll Learn
Lipids are present in cheese at levels above 20%
The complex phospholipids in milkfat make up a highly glycosylated and protein-embedded plasma membrane around each milk fat globule. The fatty acids in milk fat are preferentially esterified at the sn-3 position, and two-thirds of the fatty acids at sn-2 are 14:0 and 16:0.
Cheese consumption has been found to increase total cholesterol and LDL-C (low-density lipoprotein cholesterol) compared to tofu or fat-modified cheese. However, compared to butter intake, cheese intake reduced LDL-C by 6.5% and HDL-C (high-density lipoprotein cholesterol) by 3.9%blood lipids and lipoproteins has been examined in several randomised controlled trials. The studies compared the effects of hard cheese and butter, which have a similar ratio of polyunsaturated fatty acids to saturated fatty acids.

Milkfat is a source of bioactive lipids
The presence of these bioactive lipids in milkfat means that it serves as an important delivery medium for nutrients, including fat-soluble vitamins. While few studies have examined the nutritional consequences of these structures and compositions, their emergence through evolution suggests that they provide distinct benefits to individuals consuming them.
Cheese consumption has been found to have an impact on blood lipids and lipoproteins in healthy adults. For example, compared with butter intake, cheese intake reduced low-density lipoprotein cholesterol (LDL-C) by 6.5% and high-density lipoprotein cholesterol (HDL-C) by 3.9% but had no effect on triglycerides. Similarly, compared with tofu or fat-modified cheese intake, cheese intake increased total cholesterol or LDL-C.

Cheese consumption reduces low-density lipoprotein cholesterol (LDL-C)
Lipids are present in cheese at levels above 20%. Milkfat is a source of bioactive lipids, which are highly absorbable and serve as an important delivery medium for nutrients, including fat-soluble vitamins.
Cheese consumption has been found to reduce low-density lipoprotein cholesterol (LDL-C). A meta-analysis of randomised controlled trials (RCTs) found that compared to butter intake, cheese intake reduced LDL-C by 6.5%. This reduction was observed despite the similar ratio of polyunsaturated fatty acids to saturated fatty acids (P/S ratio) between hard cheese and butter.
The effect of cheese consumption on LDL-C has also been compared to that of tofu and fat-modified cheese. As expected, based on the P/S ratio of the diets, cheese intake increased LDL-C compared to tofu or fat-modified cheese intake.
The specific lipids present in cheese include triacylglycerols, which contain 24-54 carbon atoms. The arrangement of fatty acids on the glycerol backbone is not random due to the specificities of the enzymes involved in biosynthesis. Additionally, milk fat contains unique fatty acids, such as 4:0, 6:0, 8:0, and 10:0, which are preferentially esterified at the sn-3 position.

Cheese contains complex phospholipids
The presence of lipids in cheese has been studied in relation to their impact on blood lipids and lipoproteins. Research has shown that compared to butter intake, cheese intake reduces low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C). However, cheese consumption has also been found to increase total cholesterol and LDL-C levels when compared to tofu or fat-modified cheese intake.
The specific types of lipids found in cheese can vary depending on the milk source and cheese-making process. For example, the fatty acid profiles of milk used for cheese-making can differ between species, as seen in a table provided in one study. Additionally, the manufacturing process of certain cheeses, such as Queso Fresco, involves milling the curd to disrupt the protein matrix and create a crumbly texture.

The triacylgylcerols in cheese contain 24–54 carbon atoms
Lipids are present in cheese at levels above 20%. In particular, there are complex phospholipids making up a highly glycosylated and protein-embedded plasma membrane around each milk fat globule. Milk fat is a source of bioactive lipids, serving as an important delivery medium for nutrients, including fat-soluble vitamins.
Several studies have examined the effect of cheese consumption on blood lipids and lipoproteins in healthy adults. One study found that compared to butter intake, cheese intake reduced low-density lipoprotein cholesterol (LDL-C) by 6.5% and high-density lipoprotein cholesterol (HDL-C) by 3.9%, but had no effect on triglycerides. Another study found that cheese intake increased total cholesterol or LDL-C compared to tofu or fat-modified cheese intake, as expected based on the P/S ratio of the diets.

Frequently asked questions
Cheese contains lipids at levels above 20%. These include complex phospholipids, triacylgylcerols, and fatty acids.
Cheese consumption has been found to reduce low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C) when compared to butter intake. However, when compared to tofu or fat-modified cheese, cheese intake increases total cholesterol or LDL-C.
While studies on the nutritional consequences of consuming lipids in cheese are limited, it is believed that these lipids provide distinct benefits due to their emergence through evolution. Milkfat, for example, serves as an important delivery medium for nutrients, including fat-soluble vitamins.
