Dr. Overberg's High Blood Pressure One of Three

High Blood Pressure – Part 1 of 3 by Jim McAfee, CCN. He graciously shared his excellent article. Jim is a 30+ years friend and nutrition colleague of mine.


Hypertension or high blood pres­sure is a common condition in which excessive pressure builds up in the circulatory system. Blood pressure is measured by two numbers. A higher number, called the systolic, is placed over a lower number, the diastolic. The unit of measure is millimeters of mercury.

A normal blood pressure is less than 120/80. Elevated is 120-129/80. Stage 1 hypertension is 130-139/80- 89. Stage 2 hypertension is over 140/ 90. A hypertension crisis is con­sidered to be a measurement greater than 180/120.

There are two types of high blood pressure. Essential is a term used when the cause is not clear. This term is used to describe over 90% of all cases of hypertension. Secondary hypertension is a term used when the cause of the elevated blood pressure is identified. The most common causes of secondary hypertension are kid­ney disease, pregnancy, and effects of medications and birth control pills.

The first medical line of treatment for high blood pressure is diuretics. They cause the body to lose water lowering blood pressure. These medi­cations can contribute to deficiencies of potassium and magnesium. The po­tassium is often supplemented while magnesium is often overlooked. This is a problem due to the fact that low magnesium can contribute to high blood pressure.

Elevated blood pressure can lead to many health problems. Elevated pressure in the circulatory system damages and narrows the arteries over time and contributes to lack of elasticity. Bulges can appear in the walls of the blood vessels. If these rupture, they can lead to life threaten­ing internal bleeding. This commonly happens in the aorta, the main artery that carries blood away from the heart.

Hypertension can contribute to angina or chest pain due to nar­rowed blood vessels. It can also contribute to an irregular heart­beat. The heart canal so become enlarged leading to heart failure.

Brain damage is a risk resulting from high blood pressure. Brain dam­age can result from strokes result­ing from rupture of leaks in blood vessels, or damage can result from the formation of blood clots block­ing blood flow. Damage to the brain can result in mild cognitive im­pairment or full-blown dementia.

Hypertension can also lead to kid­ney damage or kidney failure. This can result in fluid accumulation fur­ther worsening a case of high blood pressure. High blood pressure can also result in damage to the eyes including retinopathy, bleeding in the eye, blurred vision,and blindness. It can also re­sult in erectile dysfunction in men.


Dash Diet

High blood pressure is strong­ly associated with a poor diet. The most commonly recommended diet is called the DASH diet (Dietary Approaches to Stop Hypertension). This diet focuses on avoiding re­fined grains, sugar, salt, and red meat. Participants are encouraged to consume whole grains, fruits, veg­etables, nuts, seeds,chicken and fish.

Of particular benefit berries and greens are often mentioned. These foods are contributors to healthy ni­tric oxide formation which works to dilate the blood vessels. Greens con­tain nitrates while nuts and choco­late contain arginine.All of these foods are precursors to nitric oxide which dilates and relaxes blood ves­sels. Berries and pomegranate have a protective effect on nitric oxide prolonging the short life of the mol­ecule and thus improving blood flow.

Mineral Causes

High blood pressure can have many causes or contributors. Among the causes are poor diet, toxic ex­posures, lack of exercise, stress, aging, sleep apnea and weight gain,and nutrient deficiencies.

Sodium and Potassium

Excessive sodium intake has long been considered a contributor to high blood pressure. Recent observations suggest that sodium creates problems when other nutrients are missing or unbalanced and when the inner lin­ing of the blood vessels is not healthy.

The ratio of sodium to potassium is of particular importance since the two nutrients are inversely related. In other words, a high intake of so­dium can lead to elimination of po­tassium and a high intake of potas­sium can lead to loss of sodium.

There is little doubt that a percent­age (about 50%) of those with hy­pertension are salt sensitive and see elevations in blood pressure when excessive salt is consumed. One con­tributing factor is a diet insufficiently supplied with potassium or overloaded with foods with a high sodium content.

A group of 98 vegetarians was compared with a matched group of non-vegetarians with similar salt in­take. The average blood pressure of the vegetarians was 126/77 while that of the vegetarians was 147/88. Only 2% of the vegetarians had hypertension while 26% of the non-vegetarians had high blood pressure. The researchers noted that the potassium intake of the vegetarians was much higher. Several studies have found an inverse associa­tion between blood pressure and the ra­tio of potassium to sodium in the diet.


Some additional notes from Jim McAfee:

Nitric Oxide and Blood Pressure

This month's newsletter was written before the introduction of NeoLife UPBEET, #3216 which is designed to increase nitric oxide production. Low levels of nitric oxide are associated with increased blood pressure. Increasing levels of nitric oxide can lower blood pressure in situations where other measures are ineffective.

The amino acid arginine is the precursor to nitric oxide. This is found in NeoLife's  Biotone, #3280. Polyphenols also improve the functioning of nitric oxide. These are found in NeoLife Tre, #3010. These two supplements are wonderful support for the new UPBEET product.

Garlic and Blood Pressure

 Garlic has been repeatedly shown to be a blood pressure lowering agent. Not only does it enhance nitric oxide functioning, but the sulfur compounds also appear to be of benefit. Garlic appears to lower both systolic and diastolic pressure by a little under ten points.

Drron's note: Anybody who heard me talk about magnesium knows why doctor's seldom add magnesium. Blood magnesium is maintained at the expense of muscle magnesium!

Enjoy poetry by Joan Walsh Anglund. So, few words, that touch so deep!   

Beauty arranges itself in the folds and crevices of Nature,

           ... and waits to be discovered.

How is drron? I am good. Sometimes Chris comes over (me), and we have good visits. Visits that leave me grateful for everything I received. After the rains everything here is growing and blooming like crazy, trying to make up for all the 100-degree days. Walks are wonderful, it feels like spring. I can just hear Chris: “Stop Ron! Look at this!” Those were the best nature appreciation lessons I received. I am of to Florida for a week of diving. This time I will take both the camera housing and the camera. Now fingers crossed for some good pictures.

How is Beau? Happy, my hunting buddy Ross is now our housemate. He feeds Beau when I am late, and shares his snacks. For Beau food is number one. Dinner should be served punctually at 5pm! Beau learned to bob for mini-marshmallows in his water bowl. He just plunges his mouth in. I have a bird feeder for mama squirrel and she entertains us with her acrobatics.

I make appointments with existing clients or their referrals, on Monday, Wednesday afternoon, and Friday. Tuesdays and Thursday afternoons I am at the Environmental Health Center. When you send me an email, follow up, call and text me that you have an email in the cue, you will get a quicker response! Use: and 972-816-5892. I welcome reminders.
