The body requires proper management of blood cholesterol and fats, because they serve essential health functions. The three essential blood components which people need to understand are HDL cholesterol, LDL cholesterol and triglycerides. The body responds differently to each lipid type, and requires specific management strategies to maintain cardiovascular health. The management of HDL cholesterol requires different strategies than LDL cholesterol and triglycerides because each type functions differently in the body. Let's dig deeper...
What are HDL, LDL, and Triglycerides
The blood transports cholesterol through proteins, which scientists call lipoproteins. The liver uses LDL to transport cholesterol to cells, but this process leads to artery wall accumulation that results in blockages. The medical community refers to LDL as "bad" cholesterol because of its harmful effects. The "good" cholesterol HDL functions as a scavenger that retrieves LDL cholesterol from arteries, before transporting it to the liver for breakdown, and elimination.
Triglycerides function differently because they represent blood fat, which serves as an energy reserve from dietary excess calories. The body uses triglycerides stored in fat cells for energy supply, when it requires fuel.
The three substances maintain essential functions, yet elevated LDL or Triglycerides together with decreased HDL levels, create conditions that increase the risk of heart disease and stroke.
HDL, on the other hand, is known as good cholesterol, because it functions as a protective agent for the heart, and people should focus on maintaining elevated HDL levels.
The heart benefits from HDL cholesterol, because it functions as a scavenger that retrieves excess cholesterol from blood vessel walls, before transporting it to the liver for breakdown. Research shows that people with higher HDL levels experience reduced heart disease risk. The target HDL cholesterol level should exceed 60 mg/dL according to medical standards.
To raise HDL naturally:
Regular aerobic exercise sessions should be part of your routine
Don't smoke if you do, and you should restrict your alcohol consumption
Your diet should include olive oil, nuts and fatty fish as sources of healthy fats
Maintain a healthy weight
High HDL levels alone do not guarantee good health, because elevated LDL and triglyceride levels can still exist. The optimal functioning of HDL depends on maintaining proper balance with other lipid components.
LDL: The bad Cholesterol you want to lower
LDL cholesterol performs its essential role by delivering cholesterol to cells, but excessive amounts lead to dangerous plaque formation on artery walls which doctors call atherosclerosis. The formation of plaque in arteries through LDL cholesterol accumulation, results in artery narrowing, which raises the chances of heart attack and stroke. The recommended LDL cholesterol level for healthy adults should be below 100 mg/dL but people with higher heart disease risk should aim for even lower levels.
Ways to lower LDL:
People should reduce their consumption of fried foods, butter and processed snacks, because they contain saturated and trans fats
Soluble fiber found in oats, beans, fruits and vegetables helps prevent cholesterol absorption
Select fats that occur naturally in avocados and nuts as your dietary choice
Physical exercise combined with weight management, helps achieve better health results
Doctors sometimes prescribe cholesterol-lowering medications to their patients.
Triglycerides: The energy fat that needs control
The body stores unused calories through triglycerides, which function as fat. High triglyceride levels develop when people consume excessive calories, sugars and drink excessive amounts of alcohol. The recommended triglyceride level for normal health should be below 150 mg/dL. The combination of high triglycerides with elevated LDL cholesterol and decreased HDL cholesterol levels, creates an increased risk of developing heart disease.
To lower triglycerides:
People should reduce their consumption of foods with added sugars and sweet beverages
Lower your alcohol intake
Select whole grains and unprocessed carbohydrates, instead of consuming refined grains and added sugars.
Maintain regular exercise
People who are overweight should work to lose weight.
A balanced lifestyle that promotes all three lipids requires these specific management strategies. A heart-healthy diet should consist of fruits and vegetables, together with whole grains, lean proteins and healthy fats. For this:
You should restrict your consumption of red meat, processed foods and sugary snacks.
Exercise for at least 150 minutes of moderate physical activity throughout each week.
Stay away from smoking while controlling your alcohol consumption.
Keep your weight in check, while learning to handle stress effectively.
Regular blood lipid tests enable people to track their HDL, LDL levels and triglycerides which helps them make necessary changes. People who have cardiovascular disease risk, should consult their healthcare provider for specific guidance about their cholesterol management.
