Heart 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.

Lower Cholesterol – How do I increase HDL cholesterol?

Finally, you want more of something instead of less! HDL (high-density lipoprotein) cholesterol is also known as the “good” cholesterol. HDL removes cholesterol from your bloodstream and carries it back to the liver. I like to think of HDL as a vacuum cleaner, picking up cholesterol LDL leaves behind in your arteries. HDL should be greater than 40 mg/dL, ideally greater than 60 mg/dL.

Physical Activity

One of the best ways to increase your HDL is through physical activity, specifically aerobic activity (jogging, swimming, biking). For results, you need at least 120 minutes of moderate physical activity each week. In this case, vigorous activity does not have more of an impact, but duration does. The longer you work out the greater them impact on HDL. Work your way up to a minimum of 30 minutes 4 days/week. If you’re not currently physically active, consult your MD before starting an exercise program.

Saturated and Trans Fats

Limiting unhealthy fats will also impact HDL, so look at your saturated fat and trans fat intake and see where you can make cuts. Your total fat intake for the day should be limited to 30% of your daily calories. Of this 30%, only 10% should be from saturated fat and ideally zero from trans fats. To attain these levels you’ll need to select healthy choices when dining out, read food labels, select healthy fats when cooking, select lean cuts of meat, etc.

Omega 3’s

Selecting healthy fats, such as omega 3’s, will raise HDL while lowering LDL. Incorporating healthy omega 3 fatty acids will also improve your total cholesterol to HDL ratio. Also, look for sources rich in omega 3 fatty acids you can add to your diet, such as fish and ground flaxseed..

Dietary Fiber

A high fiber diet does not directly boost HDL levels. However, a high fiber diet plays a role in lowering LDL cholesterol. As LDL is lowered, your Total Cholesterol to HDL ratio improves. For the greatest impact, eat a diet especially rich in soluble fiber and select whole grain products, fruits, and vegetables daily.

Alcohol

Alcohol plays a role in raising HDL levels also. I’m not a big advocate of using alcohol to raise HDL, so if you already consume alcohol 1-2 drinks per day can raise levels. More than 1-2 drinks per day will increase your health problems. If you do not drink, do not start.

Heart Disease – Use Vitamin C to Decrease Heart Disease Risk

A new Norwegian study – Diet and Omega 3 Fatty Acid Intervention – found individuals who increased their intake of fruits and berries decreased carotid artery thickening (atherosclerosis – hardening of the arteries), which leads to increased risk of heart disease.

The study followed over 560 men with an average age of 70 years-old for three years. Throughout the three years carotid artery thickness was measured and food intake was assessed via food-frequency questionnaires. Participants who increased vitamin C rich foods, such as fruit and berries, along with a Mediterranean diet plan had reduced arterial thickening. The more vitamin C the less the thickening.

The study concluded that even the elderly can make diet changes and see positive health benefits. We’ve known that fruits are an essential part of a heart healthy diet plan and this diet re-emphasizes that point.

Heart Health – Are Omega 6’s Good or Bad?

I and other experts so frequently discuss omega 3 fatty acids and the health benefits that you may think all other types of fat are “bad”. That’s not the case. There are many types of heart healthy fats, including omega 6 fatty acids. At least 5-10% of your daily calories should come from omega 6 fatty acids. Some sources of omega 6’s are safflower, sunflower, and soybean oils. Replacing unhealthy fats in your diet with heart healthy unsaturated fats (such as omega 6’s) can decreased coronary heart disease by 24%.

The problem comes from our diets containing too much omega 6. The typical American diet is very high in omega 6 fatty acids. This leads to problems with inflammation when the ratio of omega 3 to omega 6 intake is drastically distorted and is why you don’t hear experts recommending you increase omega 6’s in your diet. You probably have more than enough already and need to work on balancing your omega 6’s with omega 3’s to promote optimal heart health.

Lower Cholesterol – How much omega 3 do you need to lower cholesterol?

Increasing the amount of omega-3 fats in our diet and decreasing the amount of omega-6 is beneficial in reducing your risk for heart disease. Most American’s consume a high omega-6 diet, with omega 3 being a common deficiency.   Omega 3 deficiencies and the imbalance between omega 3 and omega 6 intakes have been linked with serious conditions, including heart attacks. Successfully maintaining a ratio of 4:1 to 1:1 omega 6 to omega 3 will help lower cholesterol levels and control high blood pressure.

Now, how much omega 3 do you need to add?

This is under debate and more research is being done. Right now the range experts recommend is from 500-2000 mg/day. Here are the current American Heart Association (AHA) recommendations.

The AHA recommends that individuals without heart disease eat a variety of fish twice a week, use heart healthy oils (flaxseed, canola, soybean oils), and consume flaxseed and walnuts.

For individuals with heart disease, the AHA recommends 1 g of EPA (eicosapentanoic acid) + DHA (docosahexaenoic acid) daily, preferably from fatty fish.

The AHA recommends 2 to 4 g of EPA + DHA daily, under physician’s care only, for individuals that need to lower triglycerides. High doses, > 3 grams/day, can result in excessive bleeding. (Do not self medicate! Talk to your MD before supplementing greater than 2 grams.)

Omega 3 Content of Different Foods

Wild Salmon, 4 oz. 1700 mg (DHA 700 mg, EPA 400 mg)
Tuna canned in water, 4 oz. 300 mg (DHA 200 mg, EPA 50 mg)
Cod, 4 oz. 600 mg (DHA 160 mg, EPA 50 mg)
Flaxseed, 1 Tbsp. 1000 mg (ALA – alpha–linolenic acid – 1000 mg)
Soybeans, dried, cooked ½ cup 500 mg (DHA/EPA 250 mg, ALA 250 mg)
Walnuts, 1 oz. 2570 mg (ALA 2570 mg)
Pecans, 1 oz. 280 mg (ALA 280 mg)
Wheat germ, ¼ cup 210 mg (ALA 210 mg)
Canola oil, 1 Tbsp 1300 mg (ALA 1300 mg)
Olive oil, 1 Tbsp 100 mg (ALA 100 mg)

Now, there’s a reason I included details on amounts of ALA, DHA and EPA for each omega 3 source. Right now, DHA and EPA have a greater link with lower cholesterol levels, lower triglycerides, and higher HDL levels than ALA. The body is able to convert ALA to EPA and DHA, but the conversion rate is low; therefore, it is best to include high DHA and EPA sources in your eating plan.

My recommendation:

As a preventive measure and to promote lower cholesterol and blood pressure control, I recommend eating fish twice a week, select a supplement that will provide you at least 1000 mg of omega 3 fatty acids daily (choose a good source of DHA and EPA), and use ground flaxseed when appropriate in your meal preparation.

Heart Health – Is fish oil safe?

Fish oil supplements are a great alternative for people that do not eat fish often to boost their omega 3 intake and promote heart health.

There’s been some media speculation about possible contaminants, such as mercury, within fish oil supplements. However, good news if you supplement fish oil, there are minimal contaminants within the supplements!

There have been several studies, specifically a report by ConsumerLab.com and Harvard Medical School, finding no mercury or PCBs within over 40 popular fish oil supplements. Fish oil is typically taken from fish, such as cod and sardines, that do not contain high levels of mercury. Also, many manufacturers distill the fish oil to remove contaminants.

Lower Cholesterol – Top Omega 3 Sources to Lower Cholesterol

If you have been following along, you know from the article "Get a Grip on Fatty Acids" that the right ratio of omega 6 to omega 3 fatty acids promotes a lower cholesterol. 
 
The goal is not to cut omega 6 fatty acids (such as corn oil, beef, and chicken) completely from the diet, but to achieve a ratio of 4:1 or 1:1 omega 6 to omega 3.  In order to attain this ratio you need to increase your omega 3 intake. 

Your options for doing this:
 
1. Eat fish at least twice a week.

If you like fish, this would be my first choice.  Fish contains DHA.  Research is starting to indicate health benefits, such as lower cholesterol, lower triglycerides, and higher HDL (good) cholesterol, linked to DHA alone.  Be aware of mercury content of fish, especially if you are pregnant. 

2. Take a fish oil supplement.

Start with the smallest bottle you can find and make sure you do not have the unpleasant side effect of burping with a fishy aftertaste.  Not everyone has this problem, so you may be fine.   To decrease likelihood of this problem I recommend taking the supplement and then eating.  That way something is "on top" of the fish oil.  Fish oil has a tendency to go rancid, so keep supplement refrigerated, especially if you buy a bottle of 250 or more.

3. Flaxseed.

You can buy flaxseed two different ways – whole seed or ground.  In order for the body to utilize the omega-3 fatty acids, flaxseed must be ground.  If the flaxseed is not ground it passes straight through the body without being absorbed.  Flaxseed is high in fiber, so by ingesting whole flaxseed you have increased your fiber intake, which is beneficial, but if you grind your flaxseed you will have the added benefit of increasing your omega-3 fatty acid intake and lowering cholesterol. 

4. Flaxseed oil supplement.

Provides the omega 3 fatty acid ALA in a simple supplement.  Now, ALA is not as effective as DHA and EPA at lowering cholesterol, but still results in an improved ratio of omega 3 to omega 6.  Again, may go rancid so refrigerate.

5. Add omega 3 nut and seed sources to your daily intake.

Especially walnuts, pumpkin seeds, Brazil nuts, and sesame seeds.  Nuts are high calorie, so watch your intake.  If you gain weight, you are not doing your heart any favors!

Heart Health – The Link Between Wine and Omega 3’s

A new study out of Europe is showing a link between wine consumption and increased omega 3 content in blood plasma. The study found that one glass of wine for women and two glasses per day for men leads to an increased use of the omega 3 fatty acids found in fish. It’s suggested that it’s not the alcohol responsible for this boost of omega 3’s, but other wine components (i.e. polyphenol antioxidants). The same increase in omega 3’s was not seen when beer or other spirits were consumed with fish.

So, if you enjoy a glass of wine combining your wine with a heart healthy fish based meal it looks like you’ll reap greater heart health rewards.

Lower Cholesterol – Understand Fatty Acids

Unless you have been living under a rock, you have probably heard the term fatty acids.  But, do you understand what they are and how the right ratio will improve your heart health?  I intend to clear up the confusion.
 
Types of Fatty Acids
 
There are numerous types of fatty acids.  I am focusing on omega 3 and omega 6.
 
Unsaturated Fats
 
Omega 3 and omega 6 fatty acids are both unsaturated fats.  To improve cholesterol levels, you want to replace the saturated fats (i.e. lard, shortening, ice cream, cheese) in your diet with unsaturated fats. 
 
What does "omega" mean? 
Most of you are familiar with the saying "alpha to omega", in other words, beginning to end.  The "omega" indicates which carbon has the first double bond on the carbon chain when you start counting from the omega end.  For omega 3, the first double bond is on the third carbon from the omega end of the carbon chain.  I know you were wanting to review a little biochemistry today! 
 
Essential Fatty Acids
 
Omega 3 and omega 6 fatty acids are also essential fatty acids. 
 
Essential fatty acids are necessary for cardiovascular health, but our body cannot synthesize them.  You can only obtain essential fatty acids through the foods you eat. 
 
Omega 3 (Linolenic Acid)

To keep things simple, I am going to use the acronyms ALA, EPA, and DHA.  These are all types of omega 3 fatty acids.  If we consume a food containing the omega 3 fatty acid ALA, our body will convert it to EPA and DHA.  Studies have shown a link between EPA, DHA, and heart disease.  More studies are needed to understand ALA’s relationship.
 
Sources:

Oils – Canola oil, Soybean oil, Flaxseed oil (good source of ALA)
Seeds and nuts – flaxseeds, walnuts, pumpkin seeds, Brazil nuts, sesame seeds <
Vegetables – avocados, some dark leafy green vegetables (kale, spinach, mustard greens, collards)
Fish (good source of EPA and DHA) – salmon, mackerel, sardines, anchovies, albacore tuna, lake trout, herring
Omega 6 (Linoleic Acid)

I am going to throw in more acronym’s – GLA and AA – omega 6 fatty acids.  Linoleic acid is converted to GLA and on into AA by the body.  Researchers are finding indications of a link between GLA and EPA, in relation to heart health and reduced blood pressure.  High intake of sugars, alcohol, trans fats, and various other factors can inhibit the conversion from linoleic acid to GLA. 
 
Sources:

Oils – Sunflower oil, corn oil, safflower oil, soybean oil, cottonseed oil, flaxseed oil
Seeds and nuts – flaxseeds, pumpkin seeds, pistachio nuts, sunflower seeds, pine nuts
Meat – chicken, beef

For optimum heart health, the ratio between omega 6 fatty acids and omega 3 should be between 1:1 and 4:1.  A practical example of what a 1:1 ratio means, for every 3 ounces of beef you eat, you would need to eat 3 ounces of tuna (I do not mean in the same meal!).  The ratio for the typical American diet is 11:1 to 30:1.  This poor ratio is linked with heart disease, among several other health issues.

Bottom Line:

For heart health, increase your intake of foods containing omega-3 fatty acids, while cutting back on omega-6 fatty acid sources.  For example, switch from corn oil to canola oil, increase the number of meals you eat that contain fish each week, and grab walnuts instead of pistachios.
