Ed is correct, however there are studies that show that an LDL consistently below 70 may actually reverse some plaque from the arteries, but not a substantial amount. Every little bit helps though!

The latter. It's a bit sad but as yet there isn't a chemical we can put into arteries to dissolve all that plaque. Of course, the plaque is a calcium build up on top of the softer fat. Its a shame there isnt a degreaser we can swallow to dissolve it all
