The study said...
In a study where people ate either olive-oil-infused Mediterranean meals or their regular diet for 3 months, the olive oil group's blood tests suggested better heart health. Specifically, their tests showed fewer markers of inflammation and oxidative damage -- thanks in part to a reduced expression of genes that influence these harmful processes.
I would think the genes that influence our colonic inflammation could also be positvley affected. I guess it's just not as cool to write about colon health compared to heart health.
