Cholesterol is the dietary lipid that is no longer limited by a Recommended Dietary Allowance (RDA). This change reflects updated research and understanding of dietary cholesterol's relationship with health, particularly heart disease. Earlier dietary guidelines recommended limiting cholesterol intake due to concerns about its effect on blood cholesterol levels and cardiovascular health. However, more recent studies indicate that for most individuals, dietary cholesterol has a minimal impact on blood cholesterol levels, especially when consumed as part of a healthy diet.

The current consensus is that cholesterol should not be a primary focus in dietary restrictions but rather, the overall quality of the diet should be emphasized. For example, focusing on the balance of unsaturated and saturated fats or increasing the intake of fruits, vegetables, and whole grains is more impactful for overall health.

In contrast, trans fats and saturated fats are still subject to guidelines due to their known adverse effects on cardiovascular health. Omega-6 fatty acids are essential fats that the body cannot produce, and while there are recommendations regarding a balanced intake, they are not limited by an RDA. Therefore, cholesterol stands out as the lipid for which the RDA limits are no longer applicable, making it the correct choice.
