How much cholesterol should come from the diet?

Türkiye Beslenme Rehberi (TÜBER), Türkiye's national dietary guideline, recommends that daily cholesterol intake from foods be kept below 300 milligrams in adults and below 200 milligrams in pregnant women. This number sits inside the fat section, because cholesterol enters the diet largely together with animal fat.

How much is the measured intake in Türkiye?

The guideline gives the measured value as well. In the group aged 19 and over, daily cholesterol intake is on average 290.3 milligrams in men and 211.0 milligrams in women. Both values are below the recommended limit, but the average in men stands quite close to it.

These two numbers are not a recommendation but a measurement. That is, they show what the situation is at the country average; personal intake can be clearly above or below this according to the person's own food choices. In the same measurement total fat consumption is given as 50.2 grams; cholesterol intake is read together with it inside that picture.

Which foods does cholesterol come from?

Animal fats are solid in structure at room temperature and contain cholesterol. The saturated fat sources the guideline counts are on cholesterol's route as well: cheeses, red meat, butter and hard margarines. The saturated fatty acid and cholesterol content of fatty meats is higher than that of lean ones.

The egg holds a separate place in this picture. The fat is concentrated in the yolk of the egg and its cholesterol content is high; but because the egg contains lecithin, which is a phospholipid, its effect in raising blood cholesterol is less than that of fatty meat and milk products. The guideline states that in healthy individuals eating one egg a day does not raise the risk of cardiovascular disease, especially in cases where red meat and its products are not consumed. The measure given for people who have cardiovascular disease is one to two times a week; in such a situation the plan is made under the supervision of a doctor and a dietitian.

Is there a lower limit as well?

Here the guideline gives a two-way warning. While a high blood cholesterol level poses a risk for heart and vascular diseases, a low one poses a risk for some cancer types and for neurological problems such as depression.

So the target is not zero. 300 milligrams is a ceiling value; staying below it is enough, and bringing it as close to zero as possible is not set as an aim.

Practical ways to lower intake

The ways the guideline gives are shared with the fat side. Foods that contain unsaturated fat are preferred over foods that contain saturated fatty acids; soft margarines and spreadable fats are chosen instead of hard margarines. Comparing the labels of similar products and taking the lowest one is the easiest step.

In food choice, lean red meat, skinless white meat and fish come forward. Fish generally contain less energy, saturated fat and cholesterol than the same amount of red and white meat. Eating the egg together with vegetables and grains also lowers its effect on blood cholesterol. Limiting processed meat products is on the same list; in products such as salami and sausage the saturated fatty acid and salt ratio is high, and limiting their consumption to at most once a week is recommended.

What does cholesterol do in the body?

Cholesterol is not only an item that gets limited. The guideline states that of the fats absorbed after being broken into fatty acids in the digestive system, part is used for energy, part is stored, and the others take part in the formation of certain structures such as the cell membrane, of hormones, and of cholesterol.

So cholesterol is a building block in the body and does not come entirely from outside. The amount taken in with the diet is only one part of this picture; that is why the recommendation is written as a ceiling and not as a zero target.

The general frame of the fat section holds here as well: 20-35 percent of daily energy comes from fat, and solid fat intake is kept at the lowest level, below 10 percent of energy. The cholesterol limit is read inside that frame.

Where does it turn into a mistake?

The first mistake is taking dietary cholesterol for a target on its own and missing saturated fat; the guideline states that blood cholesterol can be lowered by lowering the saturated fat in the diet, so the two items walk together. The second mistake is taking the egg off the list altogether.

300 milligrams is an upper value given for a healthy adult; the target of a person whose blood cholesterol has been measured may differ from it. This content has been prepared to support general nutrition literacy; it does not take the place of medical diagnosis or treatment and does not carry the character of personal nutrition advice. A personalized plan is prepared only by a qualified dietitian; if there is pregnancy, chronic illness, regular medication use, child nutrition or a clinical condition, supervision by a doctor and a dietitian is required before starting a plan.
