Cocoa and high blood pressure

cocoa

Now, I would have thought that a good cup of cocoa would certainly make you feel better but because of its high caffeine content I wouldn’t have thought of it as a treatment for high blood pressure.

But who am I to disagree with researchers from Harvard? It seems that although 3 in 10 of us in the UK suffer from the condition there is one place in the world where it is virtually unknown. The Kuna Indians live on a group of islands off the Caribbean coast of Panama and hypertension does not exist there. Once the islanders reach 60, they have a perfect average blood pressure of 110/70 which is something to be envied and they also have much lower death rates from heart attacks, strokes, diabetes, and cancer.

So what’s their secret? It is certainly not their salt intake as that is as high as in the UK, but because they drink 5 cups of cocoa every day. WE know that the flavonols in cocoa stimulate your body’s production of nitric oxide and that boosts blood flow to your heart, brain, and other organs. If you are taking a daily aspirin to thin your blood you might like to know that one study found cocoa thins your blood just as well. Certainly tastes better, and one Harvard Medical School professor claims cocoa can also treat blocked arteries, congestive heart failure, stroke, dementia, and even impotence.

No more to be said really, but I would stick to organic cocoa and I am not sure if the islanders make it with milk or not, but if you do then make sure that’s organic too so you get the maximum benefit

Common virus may be cause of high blood pressure

High blood pressure can lead to an increased risk for heart disease, stroke and kidney disease with 1 in 20 adults in the UK being affected and as many as 70 percent of adult diabetics. It’s causes can be varied, from genetic predisposition, medical conditions and stress, but now there may be a completely different explanation. Researchers at Beth Israel Deaconess Medical Center believe that a common viral infection might also be a cause.

The virus in question is cytomegalovirus, part of the herpes family, and it infects between 40 and 80 percent of adults worldwide. It is spread through bodily fluids such as saliva and urine, and can be transmitted from person to person through close bodily contact. Like most other herpes-type viruses, once you’re infected by CMV it will remain dormant in your body for the rest of your life, though you may never show any symptoms. If a woman has CMV it can be passed on to her unborn child and it is estimated that one in every 200 babies will be born with congenital CMV.

Viruses have the ability to turn on human genes and, in this case, the CMV virus is enhancing expression of renin, an enzyme directly involved in causing high blood pressure a whole new approach to treating hypertension, with anti-viral therapies or vaccines becoming part of the prescription.”

This breakthrough came about because for the first time researchers were brought together from a combination of disciplines including allergies, cardiology, infectious diseases and pathology. This collaborative venture meant that insights were shared and led to a statement from author Clyde Crumpacker, MD the co-author of the study and Professor of Medicine at Harvard Medical School that.. “This new discovery may eventually provide doctors with a whole new approach to treating hypertension, with anti-viral therapies or vaccines becoming part of the prescription.”

Heart attack risk linked to bodys fat distribution

The link between heart attack risk and being overweight is well-established, but now it seems that it is not so much how much extra weight you are carrying, but where it is on the body that increases the risk factor. Two studies, one in the US at the Medical College of Wisconsin and another at Tel-Aviv University in Israel indicate if extra weight is all carried on the stomach and abdomen then you need to take action. In the two separate studies 20,000 subjects had their body mass index (BMI) compared to their waist measurement in relation to cardiovascular disease risk factors. The bigger the waist, the risk of high blood pressure, high cholesterol and high glucose levels were found to be significantly stronger than the link between those same factors and BMI.

The leader of the Israeli study, Dr David Tanne, pointed out that excessive abdominal fat also raises the risk of other factors associated with metabolic syndrome, such as type 2 diabetes. Their research also found that during a 23-year follow up period that those subjects with excessive abdominal fat were one and a half times more likely to suffer a stroke compared to subjects with the lowest abdominal fat.

What can you do?
Whether you can’t see your feet when looking down, or are just a little soft around the waist, it pays to take preventive action. Heart disease and stroke risk are not to be taken lightly and although regular exercise is certainly essential there is another factor that might help.

Canadian researchers reported in a study published last year in the Journal of Nutrition that having a higher intake of protein might help. Like the other researchers they were also measuring their subjects to assess waist-hip ratio (WHR). The result was that those with the highest waist-hip ratio, indicating excessive abdominal fat, were found to have the lowest intake of protein.

Why would protein have this effect?
A fatty acid called conjugated linoleic acid (CLA) might provide the answer. CLA is most abundant in protein-rich dietary sources such as meat and dairy products. It’s also available in supplement form, and studies have shown that CLA supplements may help reduce body fat mass, but as always take the simplest route first and look at your diet before taking supplements, and then only on the advice of your doctor.

High blood pressure in pregnancy may pose long-term risk

High blood pressure is closely monitored during pregnancy but there is new evidence from a study at the Mayo Clinic in the USA that it is an under-recognized risk factor for cardiovascular disease. Compared with women who have had normal blood pressure throughout their pregnancies, those who had high blood pressure are at greater risk of heart disease later in life. One reason could be that having high blood pressure in pregnancy has some of the same risk factors for cardiovascular disease such as diabetes or obesity. Another theory is that hypertension in pregnancy could induce long-term metabolic and vascular abnormalities that might increase the overall risk of heart disease later in life. Anyone with a family history of heart disease is well advised to have their blood pressure very closely monitored during pregnancy.
