The Saturated Truth: Why Excessive Butter Consumption Is a Silent Killer for Your Heart

From a vascular elasticity perspective, a diet heavy in animal fats can make your blood vessels less responsive. Healthy arteries need to be able to dilate and constrict easily to manage blood flow during exercise or stress. High intake of saturated fats can impair the endothelium—the thin membrane lining the inside of the heart and blood vessels. When the endothelium doesn't function correctly, your body loses its ability to regulate blood pressure naturally, making you more susceptible to the sudden spikes in pressure that cause internal damage.
