The Study
No association between LDL cholesterol levels and cellular membrane integrity assessed with phase angle: Insights from the MALIPID study.
This study looked at a group of people and checked if their cholesterol levels were connected to how healthy their cells looked, but it didn’t change anyone’s cholesterol — it just measured what was already there. So it can only say 'these two things didn’t seem linked here,' not that one causes the other.
Analysis score
Maximum 44 for a cross-sectional study.
Where the score came from
Scientists checked if having very low cholesterol makes cell membranes weaker, using a special electrical test called phase angle.

Key takeaways
Summary
Based on the study abstract and findings.
- 1This suggests that even very low cholesterol levels don't seem to damage cell membranes in this group of high-risk adults.
- 2People with LDL cholesterol below 55 mg/dL had the same phase angle as those with 55 mg/dL or higher.
- 3Age and kidney function affected phase angle, but cholesterol did not.

Cholesterol is a molecule that is necessary for maintaining the structure of cell membranes and for producing steroid hormones and vitamin D.
In adults at high risk for heart disease, LDL cholesterol levels of 55 mg/dL or higher do not correlate with changes in cellular membrane integrity measured by phase angle at 50 kHz, even when accounting for age, sex, body composition, and other biochemical factors.
In adults at high risk for heart disease, phase angle decreases with older age and increases with better kidney function, but does not change with LDL cholesterol levels.
Among adults at high risk for heart disease, the measure of cellular membrane integrity called phase angle is the same whether their LDL cholesterol is below 55 mg/dL or 55 mg/dL and above.
