Coffee in Improved Vascular Function in Reduced cardiovascular Risks and Complications

Coffee may have a profound effect on the stimulated function of arteries and veins to provide nutrients and fluids to the body through blood and water circulation, a joint study suggested.

Vascular function is the action of arteries and veins, in involving blood and water circulation in the body.

Coffee, a popular and social beverage all over the world, particularly in the West, is a drink made from roasted bean from the Coffea plant, native to tropical Africa and Madagascar.

According to the study lead by the University of Reading, chlorogenic acids isolated from the coffee roasted bean, acutely improved vascular function, partly acting as mediators mediated by 5-CQA in regulated the normal function of arteries and veins.




In an acute randomized, controlled, cross-over human intervention trials conducted to examine the impact of coffee intake, matched for caffeine but differing in CGA content (89, and 310 mg) on flow-mediated dilatation (FMD) in 15 healthy male subjects, in compared a second intervention trial conducted with 24 healthy male subjects, the impact of pure 5-caffeoylquinic acid (5-CQA), the main CGA in coffee(5-CQA; 450 mg and 900 mg) on FMD, researchers filed the following results
1. Low and high CGA(89 mg and 310 mg CGA) intake, showed a significant effect on vascular function 1 hour after injecting coffee
2. Coffee intake was found closely associated with the paralleled to the appearance of CGA metabolites in regulated the normal function of arteries and veins at 5 hours

3. 5-CQA (450 mg) expressed an improvement by FMD assay after i hour of administration.



The information findings suggested that coffee has a strong effect in activated vascular function through its phytochemicals, including CGA and its metabolites in plasma, 3-, 4- and 5-feruloylquinic acid and ferulic-4'-O-sulfate at 1 h and isoferulic-3'-O-glucuronide and ferulic-4'-O-sulfate.

Other, in a total of 38 men and 37 women with a mean ± SD age of 38.5 and body mass index of 24.1 randomly assigned to 3 groups: a control group that did not consume coffee or a placebo and 2 groups that consumed 400 mL coffee/d for 8 wk containing a medium (MCCGA; 420 mg) or high (HCCGA; 780 mg) CGA content, researchers filed the results as follow
1. Coffee consumption over the period indicated and after 1 hour showed a significant presence of caffeic and ferulic acid concentrations in the coffee-drinking groups, with different values in 2 coffee injection group.
2. In the same time as in 1, the levels of antioxidant expression increased substantially in 2 coffee intake group, but undetectable in the control group or placebo.
3. All amount of antioxidants and phytochemicals creased to exist after 8 weeks.

The evidence in the study demonstrated an acute effect of coffee in promoting of vascular function in improved nutrients and fluids transportation by arteries and vessels.



Dr. Agudelo-Ochoa GM, the lead author said, "Both coffees, which contained CGAs and were low in diterpenes and caffeine, provided bioavailable CGAs and had a positive acute effect on the plasma AC in healthy adults and no effect on blood lipids or vascular function" and "The group that did not drink coffee showed no improvement in serum lipid profile, FMD, BP, or NO plasma metabolites".

Taking together, there is no doubt that coffee consumption have an enormous effect o improved vascular function in reduced risk of cardiovascular incidence and complications.
