The team then measured levels of C-reactive protein in their blood. CRP is a marker of inflammation (炎症) linked to higher risk of cardiovascular disease (心血管疾病) and problems like diabetes.
"Because we were collecting biological samples throughout, we were able to look at CRP levels in subjects prior to their
