Your Diet May Affect Cholesterol Differently Depending on Your Genes, New Study Suggests

Low-carbohydrate diets have become increasingly popular for weight management and blood-sugar control, but their effect on cardiovascular health can vary depending on what foods replace carbohydrates. A new study suggests that genetics may be one reason why some people experience a much larger increase in LDL cholesterol than others.

Researchers found that individuals carrying certain genetic characteristics may be more sensitive to the cholesterol-raising effects of saturated fat. This is particularly relevant when a low-carbohydrate diet contains substantial amounts of foods such as butter, fatty meats, cheese and other sources of saturated fat.

LDL cholesterol is an important cardiovascular risk factor because persistently elevated levels can contribute to plaque formation inside arteries. However, the study also highlights that dietary recommendations cannot always be reduced to a single rule that works equally well for everyone.

The findings reinforce the importance of monitoring cholesterol rather than assuming that a diet is automatically heart-healthy because it is low in carbohydrates. People following restrictive diets may need to consider the quality of fats, fiber intake and their individual cardiovascular risk profile.
