Do egg yolks raise cholesterol? Know its impact on heart health and who should avoid them

Egg yolks have long been viewed with caution due to their cholesterol content, historically linked to increased heart disease risk. However, modern research has reshaped this narrative. According to a study published in MDPI, consuming whole eggs, including the yolk, does not significantly raise blood cholesterol levels in most people. In fact, egg yolks are a rich source of essential nutrients such as vitamins A, D, E, and B12, along with healthy fats, choline, and antioxidants like lutein and zeaxanthin.
