Goal of Prudent diet, Total Cholesterol : HDL ratio should be less than:-
**Core Concept**
The goal of a prudent diet is to promote cardiovascular health by reducing the risk of atherosclerotic cardiovascular disease (ASCVD). A key indicator of this risk is the total cholesterol to high-density lipoprotein (HDL) cholesterol ratio. This ratio reflects the balance between the atherogenic and anti-atherogenic effects of cholesterol.
**Why the Correct Answer is Right**
The total cholesterol to HDL cholesterol ratio is a well-established predictor of cardiovascular risk. A ratio of less than 3.5 is generally considered desirable, as it indicates a lower risk of ASCVD. This is because HDL cholesterol has anti-inflammatory and anti-atherogenic properties, which help to counterbalance the atherogenic effects of total cholesterol. When the ratio is high, it suggests an increased risk of cardiovascular disease.
**Why Each Wrong Option is Incorrect**
**Option A:** A ratio of 4 is not considered desirable, as it indicates an increased risk of ASCVD.
**Option B:** A ratio of 5 is even higher and suggests a greater risk of cardiovascular disease.
**Option C:** A ratio of 3.5 is the correct answer, as it is the threshold below which the risk of ASCVD is considered lower.
**Clinical Pearl / High-Yield Fact**
A prudent diet is characterized by high consumption of fruits, vegetables, whole grains, and lean protein sources, and low consumption of saturated and trans fats. This dietary pattern can help to lower the total cholesterol to HDL cholesterol ratio and reduce the risk of ASCVD.
**Correct Answer: C. 3.5**
