FIT WebQoof: Is Dietary Cholesterol Safe for the Heart?
A WhatsApp message claims that the US government has withdrawn its recommendations to restrict consumption of cholesterol because it does not contribute to heart problems. Some important parts have been highlighted:
Some Basics About Cholesterol
Dr Udgeath Dhir, Director, Cardio Thoracic Vascular surgery, Fortis Memorial Research Institute, told FIT:
However, he cautions, this does not mean an excessive amount of it is safe.
Dr Nihar Mehta, Consultant Cardiologist at Jaslok Hospital and Research Centre, explains,
Lipoproteins are particles through which cholesterol is transported in the blood. Low-density lipoprotein (LDL) is commonly referred to as ‘bad cholesterol’ as it is carried from the liver to arteries and body tissues. High-density lipoprotein (HDL) cholesterol is known as ‘good cholesterol’, the kind that travels back to the liver.

But Does Diet Matter?
Both doctors agree that diet has a crucial role to play in a person’s health. Even though dietary cholesterol contributes only a part of the total cholesterol in the body, its modification can go a long way in keeping levels of LDL low.
On whether there is an ideal amount of cholesterol that should be consumed, Dr Dhir said,
It is difficult to state a generalized number as many factors need to be considered for each particular individual. Family history, body weight, habits like smoking or alcohol, medical history of diabetes, hypertension etc. — all this decides how stringent dietary recommendations are for a particular person.Dr Udgeath Dhir
Dr Mehta suggests that even though genes and liver function determine a lot of the cholesterol level in the body, the need for a healthy diet cannot be discounted.
Dr Dhir agrees and recommends a shift towards a more Mediterranean diet, comprising more fruits, vegetables, legumes, cereals, nuts, whole grains, fish and poultry, while minimizing consumption of refined carbohydrates, processed food and sugar.
Most importantly, the doctors recommend staying away from junk food because of their high saturated fat content.
What did the 2015 Dietary Guidelines for Americans Actually Say?
While it is true that the consumption cap of 300 mg per day (a key recommendation from the 2010 Dietary Guidelines) is not included in the 2015 edition, the report explicitly mentions:
It further states:
- Individuals should eat as little dietary cholesterol as possible.
- In general, foods that are higher in dietary cholesterol, such as fatty meats and high-fat dairy products, are also higher in saturated fats.
- Strong evidence from mostly prospective cohort studies but also randomized controlled trials has shown that eating patterns that include lower intake of dietary cholesterol are associated with reduced risk of CVD, and moderate evidence indicates that these eating patterns are associated with reduced risk of obesity.
- Dietary cholesterol is found only in animal foods such as egg yolk, dairy products, shellfish, meats, and poultry. A few foods, notably egg yolks and some shellfish, are higher in dietary cholesterol but not saturated fats. Eggs and shellfish can be consumed along with a variety of other choices within and across the subgroup recommendations of the protein foods group.
