Health numbers can tell us a lot about the condition of our bodies, and one that many of us pay close attention to is cholesterol. However, it can be tricky to understand what cholesterol numbers mean and how to keep them in check.
Cholesterol is a waxy substance found in blood lipids, and it's an essential component the body uses to build and maintain healthy cells and hormones. While cholesterol is important for good health, it’s a measurement that many of us struggle to control. This is because cholesterol can take on two forms that impact the body differently.
One form is low-density lipoprotein cholesterol (LDL) which is known as “bad” cholesterol. The other form, high-density lipoprotein cholesterol (HDL) is “good” cholesterol.
Too much LDL creates plaque that can accumulate and clog the arteries causing heart disease and stroke. On the other hand, HDL is good because it helps clean artery walls and carry away excess LDL. This is why it’s smart to keep LDL cholesterol under 100 and HDL at 60 or above. Together, the total amount of cholesterol circulating in the blood should be under 200. This is known as “total cholesterol.”
High cholesterol has no symptoms and many people are unaware of their risk. However, factors that can increase the risk of developing high cholesterol such as diet and physical activity are modifiable.
For instance, about 25% of cholesterol comes from foods such as meat, fish, and dairy while the rest is made by the human body. This is how a person’s diet can influence the type of cholesterol in one’s body. Eating a diet rich in unsaturated fats including omega-3 fatty acids promotes the production of HDL. Sources like avocado, walnuts, and olive oil can help. Also, adding soluble fiber can help to remove
LDL, and reducing red meat and full-fat dairy products can lower the amount of LDL introduced to the body.
Along with good nutrition, adequate physical activity improves total cholesterol. Cardiovascular exercises like swimming and running work to reduce bad cholesterol by increasing HDL. Resistance training also plays a part in enhancing the benefits of cardio. Including weights, resistance bands, and bodyweight movements in your routine can make an impact.
Of course, not all risk factors are controllable. For example, age, family history, and gender can play a part. However, lifestyle factors like a heart-healthy diet, regular exercise, and weight management help to reduce your risk of heart disease and stroke. So, do your part to take control of cholesterol; you might just realize how much better you feel.
