Eating Fish Can Boost Your Good Cholesterol Levels (Even More Than We Thought)
Succulent Grilled Salmon New research helps clarify why eating fatty fish regularly is beneficial for health. Scientists from the University of Eastern Finland confirm that people who eat fish three to four times per week have more large high-density lipoprotein (HDL) particles in the blood than those who eat it less frequently. Large HDL particles are thought to lower the risk of cardiovascular disease.
Population studies show HDL cholesterol, known as good cholesterol, and large HDL particles help clear away excess cholesterol from the arterial walls, while small HDL particles may have the opposite effect. Since it is the buildup of plaque that leads to reduced blood flow and the formation of blood clots within the arteries, a factor that curtails this process is very valuable.
In the study published in PLOS ONE, 131 middle-aged adults at risk of developing cardiovascular disease were asked to record their dietary practices. The participants ate fatty fish such as salmon, herring, rainbow trout and vendace, which were prepared without butter or cream. Before and after a three-month period, their blood samples were tested using a state-of-the-art detailed evaluation method that allowed the researchers to measure the amounts of 14 different particle classes. The positive changes in lipids were noted in the participants who increased their fish intake.
Researcher Maria Lankinen cautioned people against complacency about their diet if their standard lipid profiles are fine, as the factors involving lipids are very complex. The team emphasized the importance of the dietary approach in treating overall and low-density lipoprotein cholesterol, known as bad cholesterol.
