3. It Could Improve Blood Flow and Lower Your Blood Pressure
The flavanols in bittersweet chocolate will stimulate the lining of arteries, the endothelium, to provide NO (nitric oxide).
One of the functions of NO is to send signals to the arteries to relax. That lowers the resistance to blood flow, and reduces your blood pressure.
Many controlled studies show that cocoa and bittersweet chocolate will improve blood flow and lower the pressure of the blood, tho’ the results are typically mild.
However, one study in folks with high blood pressure pointed out no harmful result, therefore take all this with a grain of salt.
The bottom line
In a nutshell, the bioactive compounds in cocoa could improve blood flow within the arteries and cause a little low, statistically significant decrease in your blood pressure.
4. Dark Chocolate Raises High-density Lipoprotein and Protects Low-density Lipoprotein from the Chemical Reaction
Consuming bittersweet chocolate will improve many vital risk factors for cardiovascular disease.
In a controlled study, chocolate was found to decrease oxidized LDL cholesterol in men considerably. It additionally exaggerated HDL and cut down on LDL for people with high cholesterol.
In case you don’t know, oxidized LDL means “bad” cholesterol that has reacted with free radicals.
It makes the lipoprotein particle itself reactive and capable of damaging different tissues, like the arteries lining in your heart.
It makes excellent sense that cocoa lowers oxidized lipoprotein. It contains an abundance of powerful antioxidants that do lead it into the blood.
Dark chocolate may scale back hormone resistance. That is another common risk issue for several diseases like cardiovascular disease and polygenic disease.
The bottom line
In general, dark chocolate improves many vital risk factors for sickness. It lowers the status of LDL. Not all, it increases HDL and enhances insulin sensitivity.
