Lower High Blood Pressure – How to Use Magnesium to Lower Blood Pressure
If you have high blood pressure, your MD has probably discussed with you sodium, potassium, and calcium as part of your treatment plan; however, the role of magnesium is often overlooked.
Magnesium is a critical player in maintaining normal blood pressure levels, as well as muscle and nerve function, blood sugar regulation, bone health, and immune system maintenance.
How Magnesium Regulates Blood Pressure
Magnesium is used in the production of prostaglandin E1, which is a powerful vasodilator. Typically, blood pressure rises as blood vessels harden and narrow, which causes the heart to exert increased force to circulate blood to body tissues. A vasodilator causes your blood vessels to relax and widen, allowing for easier blood flow and results in a lower blood pressure.
Magnesium also regulates the level of sodium, potassium, and calcium within cells. Sodium and potassium work together to maintain normal blood pressure levels and must be properly balanced. Too much sodium with too little potassium leads to high blood pressure, while the opposite – too little sodium with too much potassium – can result in low blood pressure. As far as calcium, individuals with adequate calcium levels tend to have lower blood pressures.
Research Findings
Research has shown an inverse relationship between magnesium and blood pressure. In other words, individuals with a high magnesium intake, typically have a low blood pressure. I’m not referring to supplements, but actual magnesium rich foods that provide 500-1000 mg of magnesium daily.
Supplemental magnesium of ~500 mg can effectively lower blood pressure. Some studies have found magnesium supplements to reduce systolic blood pressure 2.7 mm Hg and diastolic 3.4 mm Hg.
Magnesium Sources
Magnesium is readily available in foods, such as peas, beans, whole grains, nuts, seeds, lima beans, squash, broccoli, spinach, and seafood. Assess your diet for sources of magnesium and make adjustments to maximize your dietary intake of this mineral, and then determine if a magnesium supplement is needed. Magnesium is most effective when calcium and potassium levels are adequate. For the best results, make sure your intake of all three minerals – calcium, potassium, and magnesium – are at ideal levels and follow a low sodium diet.
Always speak with your MD about any supplements you take. Oftentimes, a basic multivitamin will meet your mineral needs without adverse interactions with medications. Steer clear of mega doses!

Eating red meat may shorten your life
A study from the National Cancer Institute found individuals consuming the most red and processed meats at greater risk of death from cancer and heart disease versus those eating lower levels.
The ten year study began in 1995 and evaluated the dietary intake of over 500,000 men and women between the ages of 50 and 71. The study divided types of meat into three categories – red meat, white meat, and processed meat.
Red meat was defined as beef, pork, ham, bacon, hamburger, hot dogs, liver, pork sausage, and steak. As well as meats found in foods like pizza, stews, and lasagna.
White meat was classified as fish, chicken, and turkey.
Processed meat included white or red meats that were cured, dried, or smoked, such as bacon, chicken sausage, lunch meats, and cold cuts.
Individuals eating red meat at the highest levels consumed ~4.5 ounces per day based on a 2,000 calorie/day diet. This is equal to approximately 2 pounds of beef or pork each week. Compare this to the group with the lowest intake of red meat at 5 ounces per week or ~ 0.5 ounce per day.
Those with the highest intake of processed meat consumed approximately 1.5 ounces per day versus the lowest intake group at 0.11 ounces per day.
Men eating red meat at the higher levels each day had a 31% greater risk of dying and women 50% greater risk of dying due to heart disease. The study found that 11% of all deaths in men and 16% of all deaths in women could’ve been prevented by consuming the lower levels of red meat. Looking at just heart disease, death due to heart disease could have been reduced 11% in men and 21% in women if red meat intake was reduced from the highest level to the lowest.
A high intake of processed was linked to a 16% increased risk of dying for men and 25% increased risk for women.
This doesn’t mean you need to switch to a vegetarian diet. Individuals eating white meat had a slightly lower risk of death.
Possible reasons for the increased risk of death linked to eating red meat and processed meat maybe due to the carcinogens formed during cooking, iron in red meat causing oxidative cell damage, and/or saturated fat in red meat increased cancer risk and elevated cholesterol levels.
Here are some tips for making wise meat selections.
- Select lean cuts of meat, such as your “loins” and “rounds”.
- Choose cuts of meat with the least amount of marbling (visible fat).
- Trim visible fat before cooking.
- Marinate before grilling. May decrease formation of carcinogens if marinated in beer or wine prior to cooking.
- Broil versus frying or roast large cuts and skim off the fat.
- Drain oil and rinse ground beef in hot water to decrease fat.

Customized Weight Loss Plan – Pick a weight loss plan and stick with it to lose weight!
The largest ever controlled trial of weight loss plans found when it comes to weight loss, the bottom line always comes down to calories.
The study was completed by researchers at Harvard and Pennington Biomedical Research Center in Louisiana. Researchers evaluated the results of four different diets providing different levels of fat, carbohydrates, and protein, including a diet similar to the low fat Ornish diet and high protein/low carb Atkins plan. The dieters were encouraged to reduce caloric intake 750 calorie, exercise 90 minutes/week, and keep a food journal.
Weight loss results ranged from a 50 pound loss to a 5 pound gain. The bottom line was reducing caloric intake and sticking with the weight loss plan. Whether the diet was low fat or high protein or whatever, did not have an have an influence.
So, if you want to lose weight you need to find a plan you can stick with for the long term. If you’ve been following my posts, you know I’m “pro” making healthy lifestyle changes and “anti” dieting. I’d love to help you by evaluating your current dietary habits and providing a customized weight loss plan you can move through step by step to achieve your weight loss goals.

Top 5 Key Strategies to Lose Weight Permanently
Barley Nutrition – How to use barley nutrition to lower cholesterol
Barley contains the same soluble fiber and beta-glucan as oats. Individuals who regularly consume barley have lower LDL cholesterol, triglycerides, and total cholesterol.
A review of studies found the beta glucan in barley linked to decreased total cholesterol of 13 mg/dl, decreased LDL cholesterol of 10 mg/dl, and a reduced triglyceride level of 12 mg/dl. The review found no relationship between barley intake and HDL cholesterol. Beta-glucan is a type soluble fiber.
There are two types of dietary fiber – soluble and insoluble. You want to include between 25-35 grams of dietary fiber in your diet everyday. Of this, soluble fiber should make up 15 grams. Soluble fiber promotes lower total cholesterol and LDL cholesterol levels.
Barley nutrition is unique in that it contains fiber throughout the entire grain kernel. For most grains, when the outer bran layer is removed you’ve also removed the fiber. This isn’t the case with barley. Pearled barley is the easiest form of barley to find. Even though the grain is processed to remove the hull, bran, and some of the inner layer, it still provides 3 grams of dietary fiber in a half cup serving. Other varieties of barley include scotch or pot barley, barley flakes, quick-cooking barley, and hulled or hull-less barley.
Including barley as a regular part of your diet is a nutritious and simple way to promote heart health, lower LDL cholesterol, and lower total cholesterol levels.

How to Lower Cholesterol in 8 Simple Steps
Coenzyme Q10 Deficiency – How much coenzyme Q10 is needed to see benefits?
Here’s another question and answer from my February interview with Dr. Cynthia Shelby-Lane regarding the need for coenzyme Q10 to prevent heart disease.
Lisa Nelson RD: How much coenzyme Q10, if any, should individuals with heart disease supplement to see benefits?
Dr. Shelby-Lane: CoenzymeQ10-H2, also known as ubiquinol, is the reduced form of coenzymeQ10 (CoQ10) that is over five times more bioavailable than ordinary (standard) CoQ10. CoQ10 plays an essential role in providing energy to the body through the mitochondria, the energy-producing organelles found in all cells. There are between 100 and 300 mitochondria inside every cell, and they are responsible for over 90% of the body’s energy production. Mitochondria can truly be described as the cell’s ‘blast furnaces,’ and CoQ10 plays a critical role in the utilization of oxygen inside these mitochondria. CoQ10 also acts as an antioxidant to protect the mitochondria against the massive free radical production that occurs during the cell’s energy-producing respiratory cycle.
CoQ10 is produced naturally in all cells, but there is an age-related decline in CoQ10 production that has been linked to a wide variety of disorders in humans. Heart cells were the first cells discovered that suffered major declines in CoQ10 with age, but we now know that CoQ10 levels decline with age in almost all cells. It is vital for our health to supply dietary CoQ10 to offset the inevitable age-related decline in CoQ10 levels that occurs throughout the human body.
CoQ10 supplementation has been strongly linked to improved cardiovascular health in a wide variety of studies. It decreases peripheral blood flow resistance, especially in the microcirculation, which accounts for up to 90% of blood flow resistance. Numerous studies have also shown that CoQ10 can improve cardiac function, support healthy blood pressure, protect brain cells, slow aging markers, and shorten recovery times in power lifting and body building.
With CoenzymeQ10-H2 you can get the therapeutic benefits of higher dose coenzyme Q10 at much lower dosage levels.
Recommended Dosage: 50 mg to 300 mg standard CoQ10 per day with meals. Most manufacturers will not specify, so standard Coenzyme Q10 is still the most used. It may be difficult for the consumer to get the more concentrated so, so this value (50 -300 mg) is for standard CoQ10. Testing is the best way to know if you are getting adequate supplementation.
To be effective, you need to take enough CoQ10 to significantly raise its level in the blood to see any beneficial effect. The amount needed to do that varies among individuals, and also depends on the potency or “bioavailability” of the CoQ10 used. Some people get a good rise with 100 milligrams, whereas others need two or three times that much to attain the same blood level. Taking too little of this supplement won’t help you.
A typical dose for heart disease is 50 to 150 milligrams a day. However when heart failure is severe, up to 360 milligrams a day taken in doses of no more than 180 milligrams at a time may be needed. Experts say that “the sicker the cardiac patient, the weaker the heart, the higher the CoQ10 dose needs to be.”
Some researchers recommend 2 milligrams of CoQ10 for each kilogram of body weight (0.9 milligrams for each pound of body weight).
CoQ10 is fat soluble. To be effective, it must be taken with some fat for absorption. Take it with a little peanut butter or olive oil. If possible, take CoQ10 in the form of soft gel capsules. They are better than dry capsules or tablets.
Dosage is determined by measuring blood levels of coenzyme Q10.
Generally, people who have heart failure begin to see an improvement in symptoms in about four weeks, although some people may take as long as three months. Maximum improvement occurs after six months, which is longer than ordinary drugs take to exhibit an effect. Once started, you must take CoQ10 continually to maintain its heart-strengthening benefits.
Safety
CoQ10 is very safe. In a large Italian study, 22 out of 2,664 patients reported mild side effects. This comes out to be less than 1 percent. The typical side effect reported is mild transient nausea. No toxicity has been found, even at high doses, in animals or humans.
Important Caution
CoQ10 is not a substitute for conventional drugs. It is usually used along with conventional therapy for best results. You should do this only under the supervision of your doctor. Heart failure is a serious condition that should not be self-diagnosed or self-medicated. If you have serious heart disease, always consult a doctor for the proper course of treatment.
