Maintain Vein Health

My dad was diagnosed to have blocked arteries about 3 years ago.  He was even prescribed to undergo thru surgery so the block from the arteries will be removed.  During that time, he regretted eating all those fatty foods when he was young until he got old.  He regretted not being able to maintain his Vein Health.  It is important to keep the veins healthy as this are where our blood comes and goes to each organ of the body, without the veins we will all be dead.   He reminds us now to eat as little fat as possible.  He maintains his via a lot of medications.
