Not a true/false call. Every claim is logged with its sources; read the exhibits below.
there was a study that was recently published men that had like atherosclerosis, they were given 2.4 grams of garlic a day. And it actually slowed the accumulation of plaques in their arteries by like 80%.
What the evidence says 01 / RECORD
This matches Matsumoto et al. (Journal of Nutrition, 2016), a randomized, double-blind, placebo-controlled trial of 55 metabolic-syndrome patients (71% men, not all men; diagnosed with metabolic syndrome rather than a formal atherosclerosis diagnosis, though the two are closely linked) who took 2,400 mg/day of aged garlic extract or placebo for about a year, with coronary plaque tracked by CT angiography. The trial found no statistically significant difference between groups in total coronary plaque volume change (0.3% vs. 1.6%, P = 0.13). The only statistically significant benefit was a reduction in low-attenuation plaque, a specific vulnerable-plaque subtype (-1.5% vs. +0.2%, P = 0.0049). The widely circulated 80% figure for overall plaque reduction is not a statistically supported result from the trial itself, which explicitly found no significant effect on total plaque burden. The study, dose, and population are real, but the 80% total-plaque claim overstates what the peer-reviewed results actually showed.
