What Total Cholesterol Levels Reveal About Heart Health
Total cholesterol is key to heart health. Learn what your numbers mean and how to stay in a healthy range.
What is Total Cholesterol?
Cholesterol is not inherently bad, and is an essential component of every cell in our body and many hormones. Without cholesterol, we would not be able to survive. Total Cholesterol represents the concentration of excess cholesterol in our blood, which are carried in particles called lipoproteins. This includes the cholesterol carried in low-density lipoproteins (LDLs), high-density lipoproteins (HDLs) as well as others, including very-low-density and intermediate-density lipoproteins (which are much less abundant in our bodies).
What does it assess?
When it comes to cholesterol measurements, the most accurate risk predictor is apoB concentration. If apoB levels are high, risk is increased regardless of Total Cholesterol level, and the opposite is also true. Understanding Total Cholesterol levels can be helpful in some to determine what strategies may be most effective in lowering apoB.
How do I optimize my Total Cholesterol levels?
A key strategy to optimize cholesterol is choosing nutrient-dense foods that support cardiovascular health. Including more antioxidant-rich foods can also help to lower LDL cholesterol. Additionally, plant-based sources of protein provide an excellent alternative to animal proteins that can elevate cholesterol levels. Omega-3 fatty acids play a pivotal role in lowering triglycerides and enhancing HDL cholesterol. These healthy fats help reduce inflammation, which is linked to heart disease, and improve lipid metabolism. Alcohol and smoking both have detrimental effects on cholesterol profiles. Reducing alcohol consumption can lower triglycerides and prevent an increase in Total Cholesterol. For tobacco use, quitting smoking has immediate benefits as it can help increase HDL cholesterol levels, reduce arterial plaque, and improve overall cardiovascular health.
What do high and low Total Cholesterol levels mean?
High Total Cholesterol can be influenced by diet, obesity, genetics and other medical conditions. When it comes to cholesterol measurements, the most accurate risk predictor is apoB concentration, regardless of Total Cholesterol levels. When it comes to cholesterol measurements, the most accurate risk predictor is apoB concentration, regardless of Total Cholesterol levels. In general, lower TC levels are associated with lower apoB levels, but this is not always true.
