The influence of dairy foods in the diet on plasma levels of total, low-density lipoprotein, and high-density lipoprotein cholesterol (TC, LDL-C, and HDL-C, respectively) was studied in 75 adult lactovegetarians (vegetarians who consume dairy products) living in the northeastern United States. This was also compared to cholesterol levels of strict vegetarians (vegans).
Dairy products were the major sources of dietary saturated fat and cholesterol. The plasma total count level was positively correlated with dietary saturated fat and dietary cholesterol. Lactovegetarians have 24% higher LDL-C levels (bad cholesterol) and 7% higher HDL-C levels (good cholesterol) than vegans. Consumption of fatty dairy products, raises LDL levels (bad cholesterol) by 3x more than it raises HDL levels (good cholesterol)
