Mediterranean Diet to Reduce Heart Disease
I’m sure you’ve heard of the Mediterranean Diet and it’s link to heart health. The Mediterranean Diet emphasizes fruits, vegetables, whole grains, fish, and monounsaturated fats (olive oil).
Those that follow a Mediterranean Diet have a reduced there risk of developing heart disease and dying from a heart attack. Even those that have survived a heart attack and lived to adopt the Mediterranean Diet significantly reduced their risk of a second heart attack and other complications.
In an interesting twist, the native Mediterranean population has gradually adopted a more Western diet leading to negative results. The Mediterranean area has seen an income rise that’s resulted in extra dollars being spent on meat and saturated fat food sources. Over the past 4 decades the average calorie intake in the Mediterranean countries has increased ~30%. So, the once healthy Mediterranean countries are now seeing the weight epidemics the US is familiar with – 75% of the population overweight or obese in Greece, with over half of the population in Italy, Spain, and Portugal following suit. These countries are now supporting the “Mediterranean Diet” as a part of their cultural heritage they can not let die.
Here’s a quick breakdown of the characteristics common to a Mediterranean Diet:
- High intake of fruits and vegetables
- Select whole grains
- Consume healthy fats (canola and olive oil)
- Eat nuts in moderation
- Low red wine consumption
- Limit eggs to less than 4 times per week
- Consume little red meat
- Eat fish regularly

Reduce Heart Disease with Glucomannan
Have you heard of glucomannan? Glucomannan is a type of soluble fiber. Research has shown that for every 1-2 grams of daily soluble fiber intake, LDL (bad) cholesterol is lowered 1%. Check out this post from Janie Ellington to learn more about glucomannan and how it reduces heart disease risk:

Raise HDL Cholesterol and Improve Memory
I recently published an article titled How to Raise HDL the Good Cholesterol and I just came across another great reason to boost HDL numbers.
A study published in Arteriosclerosis, Thrombosis and Vascular Biology indicates higher HDL levels equal higher scores on memory tests. This was a 5 year study of ~3700 men and women with an average age of 55 to 61 years-old. The memory test included hearing a list of twenty words and then writing down all the words participants could remember within 2 minutes.
No link was found between triglycerides nor total cholesterol and memory performance. Nor was a link identified between HDL and Alzheimer’s.

Use Plant Sterols for Heart Health
One way to improve heart health and lower LDL (bad) cholesterol is to include plant sterols as part of your everyday diet. Plant sterols, also called phytosterols, actively remove cholesterol from the body by blocking cholesterol absorption in the intestine.
Eating 2 grams of plant sterols each day will on average reduce your LDL cholesterol 10%.
Plant sterols occur naturally in foods at low levels, so some foods (such as margarines, mayonnaise, and dairy based drinks) have been fortified. Here are some options you can use to increase your plant sterol intake and promote a healthy heart!
Avocados, 1 small 0.13 grams
Corn Oil, 1 tablespoon 0.13 grams
Sunflower Seeds, 1/4 cup 0.19 grams
Oat Bar with plant sterols, 1 bar 0.4 grams
Orange Juice with plant sterols 1.0 gram
Vegetable oil spread with plant sterols, 1 tablespoon 1.0 gram
Fruit & yogurt flavored minidrink with plant sterols, 3 oz. bottle 2.0 grams

Do I need to be concerned about high HDL levels?
My LDL is 50, my HDL is 160 and my triglycerides 90. Do I need to be concerned about my high HDL levels?
The above question is one I recently answered for a visitor to The Health Central Network. I thought readers of this blog may be interested in the answer as well, so here it is.
HDL is the good cholesterol and does not contribute to arterial plaque that leads to heart disease. HDL actually does the opposite and reduces the plaque lining your artery walls. A high level is a good thing and reduces your heart disease risk. If taking medications, speak with your MD to double check whether your medication is playing a role.
Now, we are learning that there are two different types of HDL molecules and of course one is “good” and the other “bad”. The only way to know which type of HDL you have and your levels is get get an expanded lipid profile. Consult with your MD to learn your options.

How to Lower Cholesterol Naturally
Do I need to take omega 3 and omega 6 together?
A reader from The Heart of Health, Jessica, sent in a question about omega 3 and 6 fatty acids. If you are struggling with weight loss, you should visit Jessica’s blog allabouthabits.com, for some weight loss motivation. She openly shares her weight loss struggles.
The question:
About omega 3’s and 6’s, I heard that they should be taken together, and not just having one omega 3 or omega 6 alone. It has something to do with digestion and breakdown process. Is that right?
The answer:
There are two types of fatty acids – essential and non-essential. The body can synthesize non-essential fatty acids, while the only way we get essential fatty acids is from what we eat. Omega 3 and Omega 6 are both essential fatty acids – we must get them from foods and/or supplements.
Omega 3 – ALA, EPA, and DHA are all acronyms that represent omega 3 fatty acids. If we consume ALA, our body will convert it to EPA and DHA.
Omega 6 – Omega 6 is also known as linoleic acid. Linoleic acid is converted to GLA, another omega 6 fatty acid, in the body. GLA and EPA (an omega 3 fatty acid) work together to promote bone and heart health.
So, yes, omega 3 and omega 6 work together and both are needed for bodily functions.
But, omega 6 does not require supplementation. The typical American diet is very high is omega 6 fatty acids. A main source of omega 6 fatty acids is corn oil, which is very prevalent in our society. Other sources include sunflower oil, safflower oil, soybean oil, sunflower seeds, pine nuts, pistachio nuts, and pumpkin seeds.
The ideal ratio between omega 6 and omega 3 fatty acids should be 1:1 or 4:1. A typical diet in the U.S. is 11:1 to 30:1. This poor ratio is linked with heart disease, among several other health issues.
Certain conditions can interfere with the conversion of linoleic acid to GLA, such as advanced age, excess alcohol consumption, viral infections, and various other factors. In these situations a GLA deficiency would be present and supplementing the GLA omega 6 fatty acid would be beneficial. However, this is not the case for the majority.
To reduce heart disease risk you want to increase the amount of omega 3 fatty acids in your diet and decrease omega 6’s. Omega 3 is a common deficiency in the U.S.
Omega 3 and omega 6 are both essential fatty acids and work together to promote health. However, if you follow a typical U.S. diet, you want to increase your omega 3 intake and decrease your omega 6 intake. Therefore, supplementing omega 3 AND omega 6 is not beneficial.
I hope my answer has not confused you more! I will be publishing at least two more articles this summer related to fatty acids.
