Which Cholesterol Number is More DANGEROUS? (LDL vs. Triglycerides)

Summary

Dr. Mitch Rice argues that LDL and triglycerides provide different information about cardiovascular risk. LDL measures cholesterol carried in the blood, but, in his view, the number alone does not show how many small, dense LDL particles are present. He describes elevated triglycerides—especially when paired with low HDL—as a warning sign that may point to insulin resistance and a higher-risk metabolic pattern, even when LDL looks normal.

He compares two hypothetical patients: one with high LDL but low triglycerides and healthy HDL, and another with normal LDL but high triglycerides and low HDL. He says the second patient’s overall pattern is more concerning, while emphasizing that risk depends on context.

Strategies and takeaways discussed

• Look beyond LDL alone. Consider triglycerides and HDL alongside LDL when discussing cardiovascular risk.
• Calculate the triglyceride-to-HDL ratio by dividing triglycerides by HDL. The presenter gives these guideposts:
  • Below 2.0: ideal
  • 2.0–3.5: worth attention
  • Above 3.5: a reason to discuss metabolic health with a clinician
• Review triglyceride levels. The presenter describes:
  • Below 100: optimal
  • 100–150: acceptable, but worth monitoring
  • Above 150: a reason for closer attention
  • 200 or higher: concerning
• Limit refined carbohydrates and added sugars. Examples include white bread, white rice, pasta, sugary drinks, and ultra-processed snacks. The presenter says excess refined carbohydrates can be converted by the liver into triglycerides.
• Consider omega-3 sources. He recommends fatty fish such as salmon or mackerel and mentions fish-oil supplements as an alternative.
• Interpret lab results in context. The video’s examples are illustrative; discuss personal results and next steps with a healthcare professional.
