For most of you this topic is something you frankly aren't interested, and neither was I till it killed my dad. Coronary artery disease is not something that develops overnight, but is a buildup over a lifetime. The main contributor to this death machine is a bad diet. When someone eats a high fat diet consistently, plaque builds up in the walls of the arteries. The 3 layers of the artery wall are the tunica externa, tunica media, and tunica interna. The tunica media is where the plaque builds up causing wall to enclose in the bloods pathway. A tear in the artery can occur which causes platelets ( clotting mechanisms) to come and patch up the tear causing further buildup on the wall of the artery.

So most of you probably know that smoking contributes to heart disease, but why? Smoking dosnt clog the arteries, but instead hardens the arteries causing them to loose their flexibility. In the case of someone with high blood pressure, this could produce a weak spot in the wall of the hardened artery and cause a fatal blowout.

Have you ever wondered how cherrios lower the risk for heart disease? Well the answer is found within your poop. Yes I said it. Earlier this semester in anatomy and physiology, I learned that eating more fiber can lower risk of heart disease which cherrios has a good amount of. Normally when the liver secretes bile( green colored) to break down food, it is reabsorbed in the cecum ( part of the large intestine) and recycled. When consuming more fiber, food moves through the digestive system faster which does not allow for the reabsorption of bile. Hence making poop green. But how does that lower cholesterol? Cholesterol is used to make bile. The more bile you eliminate from your system the more bile you have to make which takes cholesterol from the body ,therefore lowering cholesterol.
