Abstract
Coconut
oil is being heavily promoted as a healthy oil, with benefits that
include support of heart health. To assess the merits of this claim, the
literature on the effect of coconut consumption on cardiovascular risk
factors and outcomes in humans was reviewed. Twenty-one research papers
were identified for inclusion in the review: 8 clinical trials and 13
observational studies. The majority examined the effect of coconut oil
or coconut products on serum lipid profiles. Coconut oil generally
raised total and low-density lipoprotein cholesterol to a greater extent
than cis unsaturated plant oils, but to a lesser extent than
butter. The effect of coconut consumption on the ratio of total
cholesterol to high-density lipoprotein cholesterol was often not
examined. Observational evidence suggests that consumption of coconut
flesh or squeezed coconut in the context of traditional dietary patterns
does not lead to adverse cardiovascular outcomes. However, due to large
differences in dietary and lifestyle patterns, these findings cannot be
applied to a typical Western diet. Overall, the weight of the evidence
from intervention studies to date suggests that replacing coconut oil
with cis unsaturated fats would alter blood lipid profiles in a
manner consistent with a reduction in risk factors for cardiovascular
disease.
