But what actually is the evidence that having high cholesterol, or high LDL low density lipoprotein levels, increases your chance getting heart disease?
You may be surprised to learn that the studies available to us do not all point towards a causal connection between high cholesterol and heart disease. Different studies point towards a number of conflicting conclusions, and ultimately the picture is a lot more complicated than most media on the topic would suggest.
The association between cholesterol and heart disease At first glance, it seems that we have substantial reasons to believe that high cholesterol and heart disease are closely linked. However, the researchers say there are contradictions to this view.

However, the strength of a review's cholesterol and heart disease is only as good as the studies they include. In cohort studies, it is often difficult to directly attribute an outcome to a specific cause, and there is always the potential that other factors are influencing the outcome.
What did the research involve? The researchers searched one literature database PubMed in December to identify English-language cohort studies that had included a general population sample aged 60 and over.
Studies had to have taken baseline measures of LDL cholesterol and then followed participants up over time, looking at the link with all-cause or cardiovascular mortality. Three authors reviewed potential studies and extracted data. From an initial 2, hits, 19 publications, covering 30 cohorts and including 68, participants, were included.
The majority of studies were excluded outright, as they didn't seem to contain anything relevant in the study title or abstract summary. The other reasons for exclusion were non-English language, participants not being representative of the general population, not measuring LDL cholesterol at baseline, and not giving cholesterol and heart disease data for older adults or looking at mortality outcomes.
