High cholesterol levels are highly correlated with cardiovascular disease. ██ ███ ███████ ████ ██ ███████ ████████ ████ ██ ███ █████████ ███ ███ ████ ███████████ ██████ ███ ████ ██████ ███ ███ ████ ████ ███ █████████ ██████████████ ████████
Why are residents of Limone exempt from cardiovascular disease despite their high cholesterol levels?
A hypothesis explaining this condition must state a key difference between residents of Limone and other people with high cholesterol. That difference must protect Limone residents from cardiovascular disease, either because of a separate health factor or because Limone offers a small sample size.

This is not relevant because it is not stated whether families in Limone have enjoyed great longevity.

This would explain less severe cardiovascular disease in Limone, but not its total absence. It does not state that cardiovascular disease is caused by stress or pollution, only that those factors exacerbate it.

This cardiovascular impact does not apply to Limone residents, so it cannot explain the absence of cardiovascular disease. Limone residents have normal blood sugar levels, but the effect described occurs only among people with very low blood sugar levels.

This difference between Limone residents and people in general can explain the absence of cardiovascular disease in Limone. Since Limone residents have a gene that prevents vascular blockage, they do not suffer from cardiovascular disease.

This does not state that residents in these areas avoid fats like those in butter. It is possible they get similar fats from a different source, or that they consume high amounts of both butter and olive oil.
