While many people celebrate having a “normal” cholesterol level, this may not be as healthy as it seems. The prevailing medical definition of “normal” might actually align with our increasingly prevalent heart disease epidemic rather than optimal health. This article explores why conventional cholesterol norms need re-evaluation and what true healthy levels might look like.
The Conventional Picture: Cholesterol’s Role in Heart Disease
Decades of research unequivocally demonstrate that LDL (“bad”) cholesterol is a primary driver of atherosclerosis – the hardening and narrowing of arteries that leads to heart attacks and strokes. Hundreds of studies involving millions of participants paint a clear picture: high LDL cholesterol contributes directly to plaque buildup in our arteries, increasing the risk of cardiovascular disease.
However, even individuals with what are considered “optimal” cholesterol levels by current standards – blood pressure under 120/80, normal blood sugar, and total cholesterol under 200 mg/dL – can still have significant amounts of atherosclerotic plaque buildup within their arteries. This startling fact suggests that our current understanding of “normal” might be missing the mark.
The Disconnect Between Current Standards and Evolutionary Reality
Consider this: before modern diets dominated, most people globally had LDL cholesterol levels around 50 mg/dL – significantly lower than what is often considered “normal” today. This finding highlights a crucial point: our bodies evolved over millions of years on a diet rich in whole plant foods, not processed foods and saturated fats. Therefore, the current “normal” range might reflect a sick society rather than an inherently healthy state.
Rethinking Cholesterol Goals
Should we then aim for LDL levels closer to those found naturally before widespread adoption of Western diets? Experts often cite 70 mg/dL as a desirable target when using lifestyle modifications to lower cholesterol. While achieving this level through diet alone can be challenging, it’s not impossible. Strict plant-based diets have demonstrated the ability to consistently achieve LDL levels in this range or even lower.
Beyond Pharmaceuticals: The Power of Lifestyle
Lifestyle changes are crucial for optimal cholesterol management and come with significant advantages over pharmaceutical interventions like statins. While statins can effectively lower LDL cholesterol, they carry potential side effects like muscle damage. Choosing a plant-based diet not only offers the benefit of naturally lowering cholesterol but also improves overall well-being, leading to better mental health outcomes and greater physical vitality.
In conclusion, while “normal” cholesterol levels might sound reassuring, it’s crucial to consider what truly constitutes optimal health for our species. By adopting dietary patterns aligned with our evolutionary history and prioritizing lifestyle modifications, we can strive for cholesterol levels that genuinely promote well-being and protect against heart disease.
