Surprising
Cocoa cut triglycerides in type 2 diabetes patients by a moderate amount in a meta-analysis of 11 trials — but the evidence is low certainty and the same study found no effect on total, LDL, or HDL cholesterol.
This is among the first meta-analyses to look at cocoa specifically for triglycerides in type 2 diabetes, so the finding is intriguing but far from settled — the low certainty and high inconsistency between studies mean you shouldn't change your supplement habits based on this alone.
A meta-analysis of 11 randomized trials involving 506 people with type 2 diabetes found that cocoa intake led to a statistically significant reduction in triglycerides (a type of fat in the blood). However, the evidence is rated as low certainty, the studies varied widely in their results, and cocoa did not improve total cholesterol, LDL, or HDL cholesterol — so the benefit appears narrow and may not be clinically important.
Where this fits in the evidence
This is among the first studies we've indexed on cocoa for Reduced Triglyceride Levels — treat it as an early signal until more research accumulates.
