It's a fact atheroma is linked to modified lipids both from diet and within our body. Oxydation, which is a very complex biochemical process, glycation another complex biochemical non enzymatic process lead to modified lipids which are integrated in LDL particles. These minimally modified LDL are recognised by macrophages in the sub endothelial space of arteries and phagocyted. With high processed industrial diet the afflux of modified lipids over a life is tremendous.
