Blueberries may help reduce blood pressure and arterial stiffness

Over an eight-week period, 48 postmenopausal women with pre- and stage-1 hypertension were randomly assigned to receive either 22 grams of freeze-dried blueberry powder -- the equivalent to one cup of fresh blueberries -- or 22 grams of a placebo powder. Participants, meanwhile, continued their normal diet and exercise routines.

At the beginning of the study, the team took participants' blood pressure and measured their arterial stiffness and select blood biomarkers.

At the end of the eight weeks, participants receiving the blueberry powder on average had a 7 mmHg (5.1 percent) decrease in systolic blood pressure, which is the top number in the blood pressure reading that measures the pressure in the arteries when the heart beats. They also saw a 5 mmHg (6.3 percent) reduction in diastolic blood pressure, or the bottom number measuring the pressure in the arteries between heartbeats.

Additionally, participants in the blueberry-treated group had an average reduction of 97 cm/second (6.5 percent) in arterial stiffness.

They also found that nitric oxide, a blood biomarker known to be involved in the widening of blood vessels, increased by 68.5 percent. That is important, Johnson said, because arterial stiffness and the narrowing of blood vessels are both a part of hypertension. This rise in nitric oxide helps explain the reductions in blood pressure.

Stiffening of the arteries appears to be associated with the progressive buildup of beta-amyloid plaque in the brains of elderly patients without dementia, suggesting a relationship between the severity of vascular disease and the plaque that is a hallmark of Alzheimer disease.

"Eating the equivalent of 100 grams of blueberries for 4 weeks, twice a day is associated with systolic blood pressure lowering that is equivalent to the effect of BP-lowering medications, new research suggests.

Investigators believe anthocyanins, compounds with antioxidant effects and the pigments that give red, purple, and blue plants their color, are responsible for this beneficial effect on the vascular system, improving endothelial function in as little as 2 weeks.

"Our research is the first study directly linking blueberry anthocyanin consumption and circulating anthocyanin metabolites to improvements in vascular function in a healthy population," principal investigator Ana Rodriguez-Mateos, PhD, Department of Nutritional Sciences, School of Life Course Sciences at King's College London, United Kingdom, told Medscape Medical News."

Täytyykin lähteä omenan syöntiin.  Samalla muistin, että ceylonin kaneli (cinnamon) viivyttää sekä Parkinsonin että Alzheimerin tautien etenemistä. Paljon muitakin etuja siitä on.

Tavallinen kaneli on yli 1/2 tl otettuna epäterveellistä, mutta ceylonin kaneli voi ottaa 2 tl vrk. Kanelia ei saa syödä kuivana, kuten allaoleva artikkeli opettaa
