Continuous consumption of 1 g of an Euglena powder for 2 months by 30 people with relatively high blood fat levels resulted in a significant decrease in the level of blood LDL cholesterol (bad cholesterol).
Dyslipidemia is characterized by abnormal levels of cholesterol and neutral fat in the blood, which increases the risk of arteriosclerosis. The levels of LDL cholesterol, HDL cholesterol, and neutral fat are used to diagnose dyslipidemia. If the levels of LDL cholesterol and neutral fat exceed the reference values, they are considered indicative of hyper-LDL cholesterolemia and hypertriglyceridemia, respectively. In contrast, low levels of HDL cholesterol can be considered indicative of hypo-HDL cholesterolemia. Most of cholesterol circulating in the blood is synthesized in the liver. Following its production in the liver, cholesterol is carried by the blood throughout the body and becomes a building material for cell membranes and hormones. This cholesterol is called LDL cholesterol. An increase in the level of LDL cholesterol facilitates the adhesion of unwanted substances to the blood vessel wall, which can lead to arteriosclerosis. On the other hand, cholesterol that is transported to the liver by blood vessels is called HDL cholesterol. An increase in the level of HDL cholesterol helps prevent the retention of cholesterol in the blood, reducing the risk of arteriosclerosis.
