Atherosclerosis is a condition characterized by hardening of the arteries. The development of severe atherosclerosis can cause severe complications like a myocardial infarction (heart attack).
Past research has suggested that maybe vitamin D can help atherosclerosis in a few different ways. For one, researchers are interested if vitamin D might be able to make your arterial walls smoother. And two, vitamin D reduces inflammation, which is involved in atherosclerosis, too.
In the current study, researchers wanted to look at vitamin D’s role in the arteries immediately after high intake of dietary fat. Taking a look at vitamin D in this circumstance can help researchers gain greater perspective of vitamin D’s role in atherosclerosis and cardiovascular disease.
After you eat a meal, your body starts to digest and distribute the food and nutrients you consumed. This is called the postprandial state. When in the postprandial state after a fatty meal, the fatty acids are delivered to your liver and can be returned to the blood as low-density lipoproteins (LDL).
A high amount of lipoproteins in the postprandial state can make your body activate an inflammatory response, sending white blood cells into your blood stream. This can increase the adhesion of the arterial walls. So, in general, postprandial inflammation is considered to be pro-atherogenic and unwanted.
