Research into cholesterol management emphasizes the importance of overall dietary patterns over individual ingredients. While saturated and trans fats—found in butter, lard, processed meats, full-fat dairy, and tropical oils like coconut and palm oil—are identified as the primary drivers of excessive cholesterol production by the liver, genetic conditions such as familial hypercholesterolemia can cause high LDL levels regardless of diet. This hereditary condition, often caused by the liver’s inability to remove LDL from the blood, is linked to genetic variants involving LDLR, APOB, and PCSK9. Regarding nutrition, research suggests that the specific time a meal is consumed does not inherently increase LDL cholesterol; rather, the primary factor is the total daily intake of unhealthy fats. As individuals age, particularly after 60, physiological changes such as a less efficient liver, slower metabolism, and hormonal shifts can further complicate cholesterol levels. Recent guidance from nutritional experts and organizations, including the Istituto Superiore di Sanità, suggests that individuals with high LDL cholesterol do not necessarily need to eliminate dairy. Instead, the focus has shifted from dietary cholesterol itself to the consumption of saturated fats. For example, while whole milk contains higher levels of saturated fats and cholesterol, skim milk is highly recommended as it provides essential nutrients like calcium and potassium while significantly reducing saturated fat intake. Clinical management also involves the strategic timing of medication. Because the enzyme HMG-CoA reductase, which drives cholesterol production, reductase reaches peak activity during the night due to the liver's circadian rhythm, night, statins with a short half-life are often most effective when taken in the evening. For statins with a longer duration of action, maintaining consistent daily usage remains the most critical factor. Health professionals, including pharmacist Marija Milić, emphasize that LDL levels should not be interpreted in isolation but must be viewed within the context of a person’s total cardiovascular risk.
