BP
Blood Pressure [BP] is the force with which blood circulates toward and away from the heart; when it is too high or high for prolonged periods, the pressure can become too strong for the arteries. This can be dangerous, especially in cases where arteries are weakened or clogged by cholesterol. High blood pressure, referred to as hypertension, is a major risk factor for heart disease, stroke, congestive heart failure, and kidney disease, the number one and three killers in the USA. Hypertension is also called the silent killer, because 20% of people have it and do not know it. In fact, 33% of non institutionalized American adults, and 53% of Nursing Home
residents are known to have hypertension (2010). It is estimated that the direct and indirect costs of high blood pressure this year in the United States alone will total $76.6 billion. Sixty per cent of people with diabetes are also hypertensive; poor diet, lack of
exercise, tobacco and alcohol use, and obesity also put people at a great risk of contracting hypertension. Many people experience no symptoms at all, while others experience dizziness, shortness of breath, chest pain, blurred vision or nausea. Standard treatment
includes antihypertensive medications, diet and exercise. (Linden, Lenz, 2001) The science behind biofeedback’s role in managing hypertension:
Biofeedback-assisted relaxation therapy has been shown in many studies to control essential hypertension. Linden, et al. reported that after 10 weeks of psychophysiologic treatment there was measurable improvement.
reductions in both systolic and diastolic blood pressure were observed. In a separate study, Yucha et al provided a multimodal training program to hypertensive individuals and also reported signi cant decreases in blood pressure.
(Kuboki, Nakao, Nomura, Yano 2003)
These studies showed biofeedback resulted in significantly greater reductions in SBP (7.3
mmHg) and DBP (5.8 mmHg) than other modalities. Another study revealed signi cant reductions in systolic blood pressure were observed over eight weeks in the patients who used the (biofeedback) device compared with controls. (Yucha, 2008) In some instances, as biofeedback trains clients to improve relaxation skills and self-regulation over blood pressure, the dosage of anti-hypertensive medication required for homeostasis is decreased; thus minimizing the burdens of chemical toxicity on the body.
Probable mechanisms of the biofeedback efficacy in hypertension is by helping clients to relax. In the relaxed state they are able to change physiological responses which cause: the constriction of peripheral blood vessels, heart racing from stress hormones, inflammation and deterioriation of blood vessels due to prolongued e ects of excessive cortisol and increased blood pressure overall. It is also able to help clients gain control over certain nervous system responses, resulting in improved circulation, body temperature and decreased sympathetic activity. These relaxing effects of biofeedback may also help reduce blood pressure by restoring proper blood pressure dipping during sleep. In addition, biofeedback can also be helpful in managing the comorbid conditions and risk factors associated with hypertension.

If you or someone you love needs help managing hypertension we invite you to share this information on the benefit of biofeedback with them today.
We have helped thousands of our clients to normalized their blood pressure naturally using Biofeedback, stress management, deep breathing, full hydration, proper life style, achieving alkaline pH, replacing regular salt with celtic salt, taking high absorption supplements containing red yeast rice, policosinol, CoQ10, Resveratol, grape seed bioflavonoid extract, complete vitamins & minerals supplements.
Pomegranate has the same action as angiotensin-converting enzyme (ACE) inhibitors. These drugs (such as Accupril and Vasotec) help lower blood pressure by blocking an enzyme in the body that is responsible for causing the blood vessels to narrow. If the blood vessels are relaxed, your blood pressure is lowered and more oxygen-rich blood can reach your heart. ACE inhibitors also lower the amount of salt and water in your body, which helps to lower your blood pressure.
In a study by Israeli researchers, pomegranate juice reduced the serum activity of ACE by approximately 36 percent.[1] The same researchers found that people with high blood pressure who drank about 2 ounces of pomegranate juice a day for a year reduced their systolic blood pressure by 5 percent to 21 percent.
Keep a log of your blood pressure while taking the medications and supplements and your own physician will reduce all medications and diuretics once you reach your target of 120/80. If you are taking diuretics, use extra potassium and eat a banana to replace lost potassium. Chek with your health care provider before reducing or stopping medication.
The discovery of CoQ10 just over 50 years ago was a breakthrough that advanced our understanding of energy production dramatically.
The biochemist who pioneered the research even won the Nobel Prize for Chemistry for it in 1978 and the studies have not stopped since.
In fact, researchers have found CoQ10 deficiency in people with almost every health problem you can imagine. Just look what some of the research has shown:
For your heart: According to the Journal of Cardiovascular Pharmacology, clinical studies have found CoQ10 promotes cardiovascular health…
For your brain: In an animal study performed at Johns Hopkins University it was shown that CoQ10 supplementation improves learning and memory…
Controlling your blood sugar: An Australian study showed that patients who took CoQ10 were able to maintain healthy blood sugar levels…
For your lungs: Researchers in Texas found CoQ10 promotes bronchial health.
A powerful antioxidant: CoQ10 has been shown to be a powerful antioxidant, blasting free radicals that can damage cell membranes and mitochondria…
Even your vision: In a recent clinical trial, taking CoQ10 for a year helped subjects see more clearly…
And your gums: CoQ10 helps improve gum and oral health…
And your skin: A German study showed that CoQ10 can help reduce wrinkles and protect skin from damaging sunlight…
It is the ultimate cell food bar none. Every single organ and system of your body needs its fair share.
But — there is a little problem…
A Tale of Two Nutrients
Let’s look at what happens with two hypothetical healthy minded people.
Take Joe. He’s very conscious about supplements and what he needs for his health.
Joe takes a popular brand CoQ10 supplement. He pays almost $50 for an 80 day supply. That is about $.62 a day.
Sounds like he is doing the right thing. He is taking one of the top antioxidants that is supposed to give him all those great health benefits listed above.
But Here is The Problem…
Our levels of CoQ10 begin to decline naturally, particularly after age 40.
By their 60’s and 70’s, some people have none at all.
Your cells may not have enough energy to function properly. You will also be more vulnerable to free radical damage that may lead to big problems.
This is why taking supplemental CoQ10 makes so much sense. And that’s what Joe is doing.
But if Co Q10 is such an essential enzyme…why have I stopped recommending you take Co Q10 every single day?
Take Co Q10 that is absorbed in your body and take it in a soft gel since it is fat soluble.
Nearly 46 percent of American adults suffer from high blood pressure, which ranks as the second greatest public health threat in the U.S.1 Your blood pressure is the force needed to push blood through your arteries, delivering oxygen rich blood and nutrients around your body. When measured, you get a high-value (systolic) and a low-value (diastolic). The high number measures the highest pressure occurring in the blood vessels while your heart is contracting and the low value measures the pressure in your arteries between heartbeats.
A reading of 120/80 mmHg is considered normal. Your systolic pressure, the top number, offers the most information about the stiffness of your arteries and the work your heart is doing to push blood. Your systolic pressure is a major risk factor for cardiovascular disease.
Initial recommendations for individuals whose blood pressure is only slightly elevated includes increasing physical activity, stopping smoking and improving your diet. According to statistics from the American Heart Association, only 1 in 5 Americans gets enough exercise, and poor eating habits may have contributed to 45 percent of U.S. deaths from heart disease, stroke and Type 2 diabetes in 2012.2
New Blood Pressure Guidelines Means Earlier Intervention
Recent studies have demonstrated an increased risk from heart disease and stroke with every 20 mmHg rise in your systolic blood pressure or 10 mmHg elevation in your diastolic pressure in people ages 40 to 89.3 Although past guidelines recommended treatment in individuals whose blood pressure was higher than 140/90 mmHg, new American College of Cardiology and American Heart Association guidelines recommend treatment for individuals whose blood pressure is 130/80 mmHg.4
These new guidelines are the first comprehensive changes made in over a decade and lower the definition of high blood pressure in order to address complications that often occur at higher numbers and allow for earlier intervention. With this new definition, the number of U.S. adults with high blood pressure rose from 29 percent to 50 percent, with the greatest impact expected among those younger than 40.
The new guidelines eliminate the category of prehypertension and now categorize individuals as having either stage 1 or stage 2 hypertension. The guidelines are:5
Normal less than 120/80 mmHg
Elevated systolic 122-129 mmHg and diastolic less than 80 mmHg
Stage 1 hypertension systolic 130-139 mmHg or diastolic 80-89 mmHg
Stage 2 hypertension systolic at least 140 mmHg or diastolic at least 90 mmHg
Hypertensive crisis systolic over 180 mmHg and/or diastolic over 120 mmHg
Links Between Your Blood Pressure and Kidney Disease
Your kidneys are two bean shaped organs located just below your rib cage on both sides of your spine. They filter up to 150 quarts of blood and flush out waste products through your urine every day. One of the reasons it’s necessary to drink enough water is to ensure healthy kidney function, essential for maintaining homeostasis in your body, including with the composition of your blood. Your kidneys produce hormones regulating the production of red blood cells and those helping to regulate your blood pressure.6
Your blood pressure is also affected by vessel constriction and your circulating blood volume; the higher the volume the more the heart muscle gets stretched by the incoming blood.7 However, as with all things, balance is necessary. Lower levels of blood (hypovolemia) are as dangerous to your heart and blood pressure as higher levels of blood volume (hypervolemia).
Your kidneys produce hormones regulating arterial and venous constriction, which affects your blood pressure. They also regulate your circulating blood volume. These two functions work together to maintain your blood pressure within normal limits. Within your kidneys are special cells responsible for sensing the amount of sodium in the filtrate, and others to sense your blood pressure.8
As blood pressure drops, the amount of filtered sodium also drops and cells release an enzyme called renin. This in turn is converted into angiotensin I, and then to angiotensin II, a peptide hormone causing vasoconstriction and an increase in blood pressure. At the same time, angiotensin II stimulates the adrenal gland to secrete a hormone, aldosterone.9
This stimulates the body to reabsorb more sodium, which pulls more water with it. The increase in sodium and water reabsorption reduces your urine output and increases your circulating blood volume. Both of these functions affect your blood pressure measurements.
How Vitamin D Is Connected to Kidney Health
Additionally, your body uses calcium and vitamin D in a continued effort to maintain blood pressure homeostasis. Although your body stores calcium in your bones, it also maintains a consistent level within your blood. If your calcium level falls, your parathyroid gland releases parathyroid hormone which increases calcium reabsorption from the kidneys and intestines,10 and stimulates calcium release from your bones. However, the parathyroid hormone also requires vitamin D to stimulate calcium absorption from the kidney and the intestine.
Unfortunately, vitamin D deficiency is common in U.S. populations,11 and those with the lowest levels have a higher risk of cardiovascular disease.12 The kidneys have an important role in making vitamin D useful within the body as they convert it from supplements or from the sun into an active form.13 However, those suffering with chronic kidney disease also experience low vitamin D levels, not from lack of absorption or sun exposure, but from lack of activation within the kidneys.
In a study14 published in the American Journal of Kidney Diseases, researchers found low vitamin D levels may be able to predict early kidney disease. Those who were deficient were twice as likely to develop albuminuria, type of protein in the urine, over a period of five years. This condition is an early indication of kidney damage.
Of the more than 5,800 men and women without albuminuria in the study, nearly 4 percent developed it during a five-year follow up. Those who were deficient in vitamin D were found to be 84 percent more likely to have protein in their urine. For this study, deficiency was defined as having less than 15 nanograms of vitamin D per milliliter of blood (ng/mL). The study’s lead author commented:15
“There is mounting evidence of the benefits of correcting vitamin D levels to prevent or delay the development of albuminuria in the general population. It is also likely patients with chronic conditions such as CKD [chronic kidney disease] may need higher vitamin D levels than the general healthy population.”
CKD is one of the most powerful predictors of premature cardiovascular disease, and emerging evidence suggests progression may be linked to low levels of vitamin D.16 Those with CKD have been found with an exceptionally high rate of severe vitamin D deficiency exacerbated by a reduced ability to convert vitamin D into the active form.
Abnormalities in vitamin D metabolism17 may also play a role in the development of secondary hyperparathyroidism in CKD. The gradual and progressive decline of the active form of vitamin D in the course of the disease may limit the ability of the kidneys to maintain adequate levels despite increasing levels of parathyroid hormone.
Uric Acid Is Connected to More Than Gout
Uric acid is a normal waste product found in blood and associated with the development of gout when present in large amounts. Gout is a painful arthritic and inflammatory condition often targeting the base of the big toe. Individuals with high blood pressure and kidney disease, and who are overweight, often have high uric acid levels as well. Your body requires a balance of uric acid as it performs as an antioxidant and a pro-oxidant inside your cells. When levels are too high it tends to increase harmful levels inside the cells where it acts as a pro-oxidant.
While an overabundance of uric acid is associated with the development of gout, a reduction in uric acid has demonstrated the ability to lower blood pressure to normal levels in a teen population.18 Researchers from Baylor College of Medicine found half the teenagers enrolled in their study with newly-diagnosed high blood pressure and higher than normal levels of uric acid responded well when levels of uric acid were reduced using treatment with allopurinol.19
The treatment reduced uric acid levels and blood pressure to normal in 20 of the 30 teens treated. Dr. Daniel Feig, pediatric nephrologist at Baylor College of Medicine, commented on the results of the study:20
“This is far from being a reasonable therapeutic intervention for high blood pressure, but these findings indicate a first step in understanding the pathway of the disease. You cannot prevent a disease until you know the cause. This study is a way of finding that out.”
Previous studies using rats found high levels of uric acid were associated with the development of high blood pressure, and this study demonstrated the same appears to be true in humans. Feig reports current antihyperuricemic pharmaceuticals may not be safe to be used as a first line of therapy for most individuals with high blood pressure.21
Higher levels of uric acid are also associated with the development of kidney stones.22 Kidney stones are hard masses forming within the kidney and can affect both children and adults. When concentrations of uric acid in the urine exceed a certain point they no longer remain dissolved and may precipitate into an insoluble substance, which then forms into stones.
The presence of high amounts of uric acid in combination with dehydration increases your risk of uric acid precipitation. Uric acid stones may be preventable using some of the lifestyle choices I discuss in my previous article, “Gout Pill Poses Major Risk for Your Heart.”
How to Get an Accurate Blood Pressure Reading
Several factors can play into the accuracy of your blood pressure reading.23 To ensure your reading is as accurate as possible, keep the following factors in mind:
Cuff size
The size of the cuff may change the blood pressure reading significantly. The blood pressure cuff will have an arm circumference range printed on the cuff. Using a cuff that is too small may artificially increase the systolic measurement between 10 mmHg and 40 mmHg.
Cuff placement
The cuff must be placed on a bare arm, not over clothing, with the edges of the cuff aligned and positioned at heart level, approximately 1 inch above the bend in your elbow. The sleeve of your shirt should be off and not rolled up.
Body position
Your body position has a great deal to do with how accurate a peripheral blood pressure measurement will be. The proper position is to have your feet flat on the floor, back supported in a chair, legs uncrossed for at least five minutes and your arm supported while sitting.
Activity
Talking to the person taking your blood pressure during the reading may increase your systolic pressure by 10 mmHg, and a full bladder may increase your systolic reading by 10 mmHg. Prior to taking your blood pressure, it is important that you sit quietly for three to five minutes and do not exercise for at least 30 minutes prior to the reading.
Nicotine, caffeine or alcohol
All should be eliminated in the 30 minutes prior to having your pressure measured.
Stress
If your blood pressure consistently measures greater than 140/90 mmHg or above at the doctor’s office, while being consistently lower when measured at home, you may have white coat hypertension. For some people, seeing the doctor is an inherently stressful experience that may temporarily raise your blood pressure. An estimated 15 percent to 30 percent of people with documented high blood pressure have white coat hypertension.24
To decrease your risk of being falsely diagnosed with hypertension in this situation, take a moment to calm down (be sure to arrive for your appointment ahead of time so you can unwind), then breathe deeply and relax when you’re getting your blood pressure taken.
Machine calibration
Home machines and automated machines must be accurately calibrated to ensure a proper reading. One study25 demonstrated some home pressure machines were off in up to 15 percent of patients. Readings from these machines may impact treatment recommendations.
Hearing ability when using a stethoscope
Many of the machines used today in hospitals and some clinics to take blood pressure are automated and don’t require someone to manually listen for Korotkoff sounds in your brachial artery. However, there remain a large number of blood pressure measurements taken by an individual listening for the change in sounds in the brachial artery. Individuals who have some hearing loss may record an abnormal reading when they don’t hear the change in sounds correctly.
How to Protect Your Kidneys
Your kidneys play a vital role in your overall health. Eating the right foods helps to improve your kidney function as certain foods help you manage blood pressure, prevent kidney stones and reduce uric acid output better than others. Here are three dietary keys to help protect your kidney function. 26
Restrict protein. Uric acid is the metabolic waste product of the breakdown of purine, found in abundance in all meats, poultry and fish. Organ meat and certain oily fish, such as herring and mackerel, tend to have higher levels of purine. It is not necessary to eliminate meat, but care should be taken to balance your protein intake. You can read more about this in my previous article, “Precision Matters When It Comes to Protein.”
An ideal protein intake is likely around one-half gram of protein per pound of lean body mass. The American Kidney Fund27 recommends restricting protein to a maximum of 50 grams if you currently have kidney disease. Discover more about your protein requirements in my previous article, “How to Prevent and Treat Kidney Problems With Food.”
Restrict fructose. Uric acid is also a byproduct of fructose metabolism. Fructose is independently associated with high blood pressure, Type 2 diabetes, obesity, kidney disease and nonalcoholic fatty liver disease. Limit your fructose intake to 25 grams per day or less, especially if you’re insulin or leptin resistant.
Drink pure, clean water. One of the most effective ways to prevent uric acid precipitation is to remain fully hydrated. Ensure your fluid intake is higher during summer months or with strenuous activities, or if you’re suffering gastroenteritis with vomiting or diarrhea.
When fully hydrated your urine should be the color of straw and you should ideally be visiting the bathroom around seven to eight times per day. Simply swapping out sweetened beverages, such as sodas and fruit juices, for pure water can go a long way toward improving your kidney function and your overall health.
Limit high-purine vegetables. Asparagus, beans, peas and spinach are plant-based foods with higher levels of purine. Moderate intake does not usually pose a problem, but meals containing large quantities should be avoided.
Avoid substances causing water loss. Certain medications, diuretics, alcohol and caffeine may increase your urine output and without proper rehydration fluid loss may result in dehydration.
