Heart HealthHeart Disease – Is flax oil or fish oil better to reduce heart disease?
A recent study published this past September compared the benefits of flax oil versus fish oil in raising blood levels of heart healthy omega 3’s. Adequate omega 3 intake is linked to lower blood pressure, lower triglycerides, increased HDL cholesterol, and reduced arterial inflammation.
Flax oil contains the omega 3 fatty acid ALA (alpha-linolenic acid), while fish oil contains EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid). The benefits of ALA continue to be studied, but EPA and DHA have been positively linked to heart benefits.
The body can convert ALA to EPA and DHA, but it’s been well known that this conversion process is not efficient. According to a recent study published in Nutrition Reviews, 8-20% of ALA is converted into EPA. From this, only 0.5-9% is converted to DHA.
To test the benefits of ALA supplements (flax oil) in amounts commonly consumed, the study followed 62 firefighters. The participants were divided into 6 groups and monitored for 12 weeks. Here are the six groups:
1.2 grams of flax oil per day
2.4 grams of flax oil per day
3.4 grams of flax oil per day
0.6 grams of fish oil per day
1.2 grams of fish oil per day
Sunflower placebo
Results showed an increase of EPA and DHA in the blood for those taking both levels of fish oil supplements. The EPA levels in red blood cells almost doubled by the studies end.
Now, the flax oil supplements did not have the same result. Those receiving 1.2 grams of flax oil daily did not show a significant rise in EPA and DHA, only ALA. The 2.4 g and 3.6 g flax oil supplements increased ALA, EPA, and DHA levels. EPA was increased 30% with a 2.4 g supplement and 40% with 3.6 g of flax oil daily. However, there was no corresponding increase in DHA. This confirmed the original belief that conversion of ALA into DHA is minimal.
The results of this study support my recommendations related to omega 3 supplements. First, consume a diet rich in omega 3 fatty acids (i.e. fish, nuts, flaxseed). Second, select a fish oil supplement high in EPA and DHA. Choose a supplement with 850 mg of DHA and EPA per gram of fish oil. Third, if you do not tolerate fish oil, select a flax oil supplement providing at least 1 gram of omega 3 fatty acids daily.

Heart HealthLower Blood Pressure – How Celery Can Be Used to Lower Blood Pressure
When you think of celery, you probably immediately think “diet” and snacking on carrots and celery instead of the food you really crave!
Well, celery does much more for your heart than simply trimming your waistline. A Chinese study found blood pressure to fall significantly in 14 out of 16 individuals with high blood pressure when they were given celery.
Exactly how celery works to lower blood pressure is not completely understood. Scientists have found celery to contain apigenin. Apigenin is a substance known to help lower high blood pressure. Celery also exhibits properties similar to diuretics and ACE inhibitors, both effective medications to lower blood pressure. Celery has been used to treat a variety of conditions – congestive heart failure, fluid retention, anxiety, insomnia, gout, and diabetes.
Mark Houston, a well-known cardiac physician, recommends eating either 4 celery stalks daily, 8 teaspoons of celery juice 3 times a day, 1000 mg celery seed extract twice a day, or ½ to 1 teaspoon of celery oil 3 times a day in tincture form. I say go with the celery stalks. The cost is low, calories minimal, taste good, and potential benefit great.
The risk of excess celery is almost non-existent, so this is a safe treatment option if you are struggling to lower high blood pressure. However, don’t counteract the benefits by slathering your celery in a high fat dip or dressing. If you need added flavor, opt for a low fat dressing or possibly peanut butter. Peanut butter provides a good source of heart healthy unsaturated fats and protein.
FYI – Non-animal sources of protein, such as beans and soy, promote lower blood pressure levels. Studies have found that individuals who consume 30% higher than average protein intake (such as 1.0 – 1.2 grams per kilogram of body weight) have reduced blood pressures. The average reduction was 3.0 mm Hg reduced systolic blood pressure and 2.5 mm Hg diastolic. So, added bonus to combine peanut butter with your daily celery intake!

Heart HealthLower 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!

Heart HealthLower Blood Pressure – What Does Chicken Soup Have to Do with 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!

Lower Blood PressureGarlic to Lower Blood Pressure
There are numerous health claims surrounding garlic. . .do you think they’re true? Let’s discuss garlic to lower blood pressure.
Research studies have found a link between the right type and amount of garlic and a lower blood pressure. The average reduction in systolic (top number) blood pressure was ~5-8 mm Hg. Garlic is linked to a reduction in diastolic blood pressure, but the decrease isn’t large enough to be statistically significant.
Garlic contains many components that may be responsible for this decrease in blood pressure.
Natural ACE inhibitors
Magnesium
Phosphorus
Adenosine
Allicin
These components promote arterial dilation, which means a widening of the arteries, to make blood flow easier and lower blood pressure.
Studies indicate 10,000 mcg of allicin are needed daily to result in a lower blood pressure. To gain 10,000 mcg of allicin you’d need to consume 4 cloves or 4 grams of garlic daily.
Some easy ways to increase the garlic in your diet:
- Chop fresh garlic and add to stews or a stir-fry.
- Use as a seasoning and add to vegetables, meat, poultry, fish and soup.
Now, you can’t rely on garlic alone to get your blood pressure back within a normal levels. But including more garlic in your diet is one easy step towards promoting a lower blood pressure. Be sure to sign up for the free course 7 Natural Ways to Lower Blood Pressure.

Lower Blood PressureHealthy Ways to Lower Blood Pressure – Hibiscus Tea and the Link with High Blood Pressure
If you are prehypertensive or have mild high blood pressure a study has found that drinking hibiscus tea may help lower your blood pressure. A study followed 65 individuals aged 30-70 years-old with initial blood pressure readings of 120-150/<95. Individuals were split into two groups, with one group drinking three cups of hibiscus tea daily. Those consuming the tea saw a 6.2 mmHg drop in systolic blood pressure (top number).
Hibiscus is a common ingredient in herbal teas, providing a fruity, tart taste and red color. Hibiscus is also a good source of anthocyanins, flavones, flavonols, and phenolic acids. This isn’t the first study to show a link between hibiscus tea and reduced blood pressure.
The three minerals that lower blood pressure
