We are what we eat, thus what we put in our bodies inevitable become part of its structure, and like I said before structure determine function.
Did you know that fat is absorbed into the body differently than proteins and carbohydrates (CHO)? When CHO and proteins are broken down and absorbed in the small intestine they are carried through the heptatic circulatory system to the liver to filter out unnecessary by-products. Fat however due to its water phobic nature is absorbed into your lymphatic system (mirrors your circulatory system, used in immunity, lymph: the clear part of blood). The lymphatic system drains into the circulatory system at the superior vena cava. If you perused the anatomy of the heart you would know that the superior vena cava is where de-oxygenated blood from the upper body enters the heart to be pumped to the lungs. The implications of that are: THE FIRST PLACE FAT GOES IN THE BODY IS YOU HEART!!!!! And since our cells take what they need to repair, and build form circulating CHO, proteins, and fats, it means your heart is getting first pick of unhealthy fats. Terrifying.
It also explains why eating processed food, which are high in fat (the bad and terrible kind) impacts immunity. Your lymph is a drainage system for your immune system and unwanted thing circulation in your blood. if it is saturated with fat, it increase the work of your lymph nodes, deceases their effectiveness at fighting off disease.
Next time you reach for that chip, chicken wing, or cookie… think about what it would look like in your heart… you may reconsider.
