The researchers had previously shown that at physiologically relevant concentrations, caffeine improved the functional capacity of endothelial cells that line the interior of blood vessels, and that the effect involved mitochondria, the cell's energy powerhouses. They showed that a protein called p27, known mainly as an inhibitor of the cell cycle was present in mitochondria in the major cell types of the heart. In these cells, mitochondrial p27 promoted migration of endothelial cells, protected heart muscle cells from cell death, and triggered the conversion of fibroblasts into cells containing contractile fibres, all of which are crucial for repair of heart muscle after myocardial infraction.
They found that caffeine-induced the movement of p27 into mitochondria, setting off this beneficial chain of events, and did so at a concentration that is reached in humans by drinking four cups of coffee. Caffeine was protective against heart damage in pre-diabetic, obese mice, and in aged mice.
Here are heart friendly foods that you can eat to keep healthy:
Oats are fibre rich foods that help bind bile acids and expel them from the body. These bile acids are made from cholesterol. A diet that includes oats is effective in lowering cholesterol levels in the body.
Berries are full of heart healthy phytonutrients and fibre, which keep all heart related ailments at bay.
Flaxseeds are rich in omega-3 fatty acids, fibre and all of these nutrients that help in boosting heart health. It is best to soak or grind flaxseeds before consuming them to derive maximum health benefits.
