Let me state right up front that I do not recommend following a low carb diet. That being said I want to share some of the latest research with you.

A study published on January 25, 2010 in the Archives of Internal Medicine compared a low carb diet versus a low fat plus orlistat diet. Researchers analyzed the effect of these two diets on weight loss and blood pressure.

Just in case you don’t know, orlistat is also known by the names Xenical and Alli.

Researchers studied 146 participants from the Department of Veterans Affairs primary care clinics in Durham, North Carolina. Participants were randomly assigned to either the low carb of the low fat plus orlistat diet, received instructions, and were monitored for 48 weeks. Some factors analyzed included body weight, blood pressure, fasting serum lipid, and glycemic parameters.

Results of the study found weight loss to be similar between the two groups at ~9% body weight. The low carbohydrate diet resulted in a lower blood pressure for participants when compared to the low fat diet with orlistat. The low carb diet lowered systolic (top number) blood pressure on average 5.9 mm Hg and diastolic (bottom number) blood pressure 4.5 mm Hg.

HDL Cholesterol and triglyceride levels improved for individuals on each diet, while LDL cholesterol improved only for those on the low fat plus orlistat diet. Glycemic parameters, such as glucose, insulin, and hemoglobin A1C only improved for low carbohydrate diet participants. Although it’s worth noting that the difference between groups was not statistically significant.

Like I said at the beginning I do not recommend a low carb diet. My first choice to promote a lower blood pressure would be the DASH diet. A study on the DASH diet was actually published in this same journal issue.

The DASH Diet alone was compared to the DASH diet in combination with a weight management and exercise plan. The DASH Diet when combined with an exercise/weight management plan resulted in an 11.2 mm Hg drop of systolic blood pressure and an average weight loss of 19 pounds over a 4 month period.

The main thing to remember is that you need to pick a plan you can stick with for the long term. Steady, consistent action is what will lead to results.

Lifting weights can cause a temporary, but dramatic blood pressure rise. Systolic blood pressure can increase up to 350-400 mm Hg and diastolic blood pressure to 150 mm Hg even if your blood pressure is typically a healthy level of 120/80 or less.

Long term high blood pressure is linked to arterial endothelial dysfunction. The endothelium is the inner lining of your artery walls. Endothelial dysfunction can result in the hardening of artery walls. Researchers have been monitoring the effects of short duration rises in blood pressure, such as what occurs during strength training, to determine the effect on endothelial function. It has been determined that acute rises in blood pressure impairs endothelial function in untrained individuals and regular resistance training helps protect against vascular dysfunction.

At one time, weight lifting was discouraged if you lived with high blood pressure. However, this is no longer the recommendation. Regular physical activity that includes moderate strength training is one of many natural ways to lower blood pressure. A study published in Hypertension monitored participants completing resistance training 2 to 5 times per week and found strength training to help lower resting blood pressure.

Including strength training and aerobic physical activity can be a positive step towards lowering blood pressure; however, you must consult your physician before beginning an exercise and/or strength training program. Strength training is not recommended if you have uncontrolled high blood pressure, untreated heart disease, or an irregular heart rate.

The current American Heart Association recommends individuals 18 to 65 years-old include moderate intensity aerobic physical activity 5 days a week for a minimum of 30 minutes and strength training at least twice a week.

The long running Health Professional Follow-Up Study has released new findings. The study found men who eat a high level of whole grains to be 19% less likely to develop high blood pressure compared to those eating the lowest levels of whole grains. The individuals with lower risks of developing high blood pressure consumed 52 grams of whole grains daily versus only 3 grams in the lower whole grain group.

Even though this study focused on men, similar results are being seen for women in the Women’s Health Study.

A few possible reasons increasing your intake of whole grains may prevent high blood pressure include better insulin sensitivity, lower blood sugar, decreased food intake to higher feelings of satiety (fullness).

Current whole grain recommendations are 85 grams per day.

How many grams of whole grains do you think you consume each? Do you have ideas for how you can increase your intake?

You’d think the stress of raising children would cause blood pressure to boil; however, a study has actually found a link between parenthood and lower blood pressure, particularly in women. The Brigham Young Study monitored 198 adults for 24 hours. Seventy percent of participants had children, participants were married and in overall good health.

The study measured blood pressure using portable devices at random times throughout the day and night. Researchers found participants with children had an average blood pressure of 116/71 mm Hg. After factoring in other issues that impact blood pressure (i.e. age, gender, body mass index, and smoking, etc.) parents had a systolic (top number) blood pressure reading 4.5 points lower and a diastolic (bottom number) reading 3 points lower than participants without children. A greater difference was seen in women. Motherhood corresponded with a 12 point difference in systolic blood pressure and 7 point difference in diastolic blood pressure.

Interesting look at how not only dietary factors influence blood pressure. What do you think? Has being a parent had a positive impact on your blood pressure? Share your thoughts below!

The latest research published in the American Journal of Clinical Nutrition found that saturated fat is not linked to heart disease as we’ve always be told. This latest study was a meta-analysis and did not find significant evidence linking dietary saturated fat with increased risk of heart disease.

A meta-analysis combines the results of several studies completed with similar theories. In this particular analysis, 21 studies were compared in regards to dietary fat and heart disease risk. I do like meta-analysis results, because they can provide a big picture look at the overall findings. However, there are weaknesses.

Here are three known weaknesses:

1. Reliance on published studies – Studies that do not show significant results have difficulty getting published. If a meta-analysis only includes studies showing a positive or negative association there could be many unpublished studies finding no link.
2. Studies included are not controlled – A meta-analysis may include studies with a poor design which can skew results inaccurately. The studies included in a meta-analysis is a subjective design made by the researchers – they get to decide.
3. Simpson’s Paradox – This deals with statistics and how study results are interpreted. There are different ways to measure results and there is no one agreed upon measurement method – with is of particular importance in the field of medicine.

Why am I sharing this information with you?

Because the results of this latest meta-analysis are interesting, but I do not recommend you throw out your olive oil and replace it with lard. It’s likely saturated fat does not deserve the “bad rap” it has received; however, that doesn’t mean excess amounts are good. Everything comes back to moderation.

I have shared in the past how the DASH Diet is one of the best tools you can use to lower and control high blood pressure. A new study found that the DASH Diet not only promotes improved blood pressure levels it also fights kidney stones.

Three large studies including over 240,000 men and women participants were evaluated and individuals whose diets most closely followed the DASH Diet plan had a 40-45% reduced likelihood of developing kidney stones compared to individuals following diets in direct contrast to the DASH Diet.

Researchers also took into account calcium intake. Calcium is involved in the formation of a common type of kidney stone – calcium oxalate kidney stones. Regardless of calcium intake those who followed the DASH Diet were less likely to develop kidney stones.

For individuals who have developed kidney stones or at risk of developing kidney stones a common dietary recommendation is to avoid foods high in oxalate, such as spinach and almonds. This more recent review of research indicates this may not be necessary. The DASH Diet strongly emphasizes a diet high in fruits and vegetables. Researchers point out that a diet high in fruits and vegetables increases urinary citrate production which inhibits the formation of kidney stones containing calcium.

7 Natural Ways to Lower Blood Pressure

I read some interesting research lately that I want to share related to chicken and blood pressure.

We know that blood pressure is a significant risk fact for heart disease and stroke. It’s estimated that around 1 billion people worldwide live with high blood pressure. Being able to control high blood pressure through food selection is very important.

The collagen in chicken is being researched for use as a blood pressure medication, with actions similar to ACE inhibitors (i.e. lisinopril). Japanese studies have found 4 proteins in the chicken that contain collagen with actions similar to the blood pressure medication when tested in rats.

Chicken legs and feet contain more collagen that chicken breast meat. FYI – The legs and feet are the yellow part of a chicken leg with a nail on the end. A “chicken collagen hydrolysate” was prepared in the study and fed to rats and the effects on blood pressure where examined. The rats showed a drop in blood pressure 4 hours after receiving the mixture orally, with the lowest blood pressure reading after 8 hours. Long term studies showed improved blood pressure after one week of treatment, with a significant reduction after 2 weeks.

The study states that the “chicken collagen hydrolysate” mixture used in the study is composed of foods that can be easily added to a typical daily diet. For individuals with high blood pressure, increasing intake of these foods will promote a normal blood pressure. What I want to know – who is going to eat a chicken leg/foot? How do the researchers think this will become a normal part of the diet? My question wasn’t answered in the study results. I’m thinking it’ll be made into a food additive that will allow certain foods to be marketed as “functional” for blood pressure reduction, but we’ll have to wait and see.

The title of this post was only used to catch your attention. I’m not recommending you eat more chicken soup to lower your blood pressure. Way too much sodium added to soup for it to be beneficial!

Too much sodium in your diet can contribute to high blood pressure and make your blood pressure treatment less effective.

Sodium versus Table Salt

First, let’s clear up the confusion about the difference between sodium and table salt. Table salt is a combination of the two minerals sodium (Na) and chloride (Cl). Table salt is 40% sodium and 60% chloride.

Sodium

Sodium is a mineral that is vital for health. Sodium maintains fluid balance, which is why it plays a key role in blood pressure control.

There is a direct relationship between sodium intake and blood pressure. Reducing sodium to 2.3 grams sodium (6 g table salt) daily is linked with decreased blood pressure levels.

Sodium Intake

A typical U.S. diet means a high sodium diet. The average American consumes 6-18 grams of table salt daily (about 3 teaspoons). The body only needs 200 mg daily. That is 30 times less than what American’s typically consume.

To be heart healthy, sodium intake should be reduced to less than 2300 mg (1 teaspoon) daily.

Sources

Sodium is found naturally in food, but most sodium we consume has been added for food preservation and preparation. To successfully reduce sodium intake you need to be aware of the table salt you add to foods and the sodium pre-added to foods.

75% of the typical American diet comes from processed foods – sauces, soups, condiments, canned foods, and prepared mixes. Fast food is another common source of sodium.

Tips to Reduce Sodium Intake

Use less salt at the table and when cooking.

If you automatically add salt to food before tasting it, this is the first place to start cutting back. You have many options for flavoring your food in place of salt – salt substitute, herbs, and spices.

If you want to try salt substitute, check with your MD. Salt substitutes contain potassium and needs to be monitored if you have kidney disorders.

Read labels when buying prepared and prepackaged foods.

When reading labels, here are some terms to avoid:

• Salt (sodium chloride)
• Monosodium glutamate (also called MSG)
• Baking soda (sodium bicarbonate)
• Baking powder
• Disodium phosphate

Select canned, frozen, and snack foods without added salt, such as unsalted nuts, unsalted broths, and no added salt canned vegetables. Better yet, switch from canned vegetables to frozen with no added salt or fresh veggies. Limit salty snacks like chips, pretzels, and salted nuts. Cheese is anther high sodium source.

Make healthy choices when dining out.

Here are some tips to enjoy a meal out and maintain a low sodium intake:

• Use pepper for extra seasoning instead of salt.
• Avoid sauces or gravies.
• Order broiled and baked meats.
• Avoid seasoned or blackened menu items.
• Avoid menu items with a lot of cheese.
• Avoid soy sauce and MSG.

Salty flavor is something you have trained your body to prefer. You can retrain your taste buds over time with the ultimate goal of lowering high blood pressure.

The link between calcium and blood pressure was noticed years ago when researchers realized people drinking hard water had less high blood pressure than those drinking soft water. Hard water contains more minerals, including calcium.

Individuals receiving more than 800 mg of calcium daily have a 23 percent decreased risk of high blood pressure versus those consuming less than 400 mg of calcium per day.

Back in 1996, scientists compiled all the research to date on calcium and high blood pressure. The results showed calcium supplements given to individuals with high blood pressure lowered systolic blood pressure (top number) an average of 4.3 mm Hg and diastolic blood pressure (bottom number) 1.5 mm Hg.

Some people respond better to supplemental calcium than others. Those with the best results include African-Americans, elderly, pregnant women, menopausal women, people with salt-sensitivity, individuals with a high sodium intake, and those with Type II diabetes.

For the best results, don’t rely on a supplement alone. Work to increase your intake of calcium containing foods – dairy. To promote heart health, select low fat dairy products, such as low fat milk, cheeses, and yogurts.

Additional calcium sources:

Leafy greens (i.e. kale, collard, turnip, mustard greens)
Broccoli
Sardines
Canned Salmon
Calcium fortified Orange Juice
Tofu (if made with calcium carbonate)

For even better results, supplement calcium along with vitamin D. One study supplemented women 1200 mg of calcium to reduce blood pressure. When they added 800 IU of vitamin D, systolic blood pressure decreased an average of 9.3 percent.

Don’t forget three other minerals affect how effective calcium – potassium, magnesium, and sodium. For calcium to have the greatest positive effect on blood pressure, your levels of these three nutrients need to be adequate as well.
