On the Kojo Nnamdi show http://thekojonnamdishow.org/
today I heard Dr. Caldwell Esselstyn talk about the dangers of eating any kind
of oil. The message I got from him on
the program was that ALL oils should be removed from the diet. Dr. Esselstyn
claimed that oils among other things caused inflammation of the lining of the
blood vessels which is a significant cause for coronary artery disease which
can lead to heart disease.
The rules of his diet
are:
1.
You may not eat anything with a mother or a face
(no meat, poultry, or fish).
2.
You cannot eat dairy products.
3.
You must not consume oil of any kind—not a drop.
4.
You cannot eat nuts or avocados
Things you can
eat are:
1.
All vegetables except avocado. Leafy green
vegetables, root vegetables, veggies that are red, green, purple, orange, and
yellow and everything in between.
2.
All legumes—beans, peas, and lentils of all
varieties.
3.
All whole grains and products, such as bread and
pasta, that are made from them—as long as they do not contain added fats.
4.
All fruits.
Over
the past 12 years he reports this diet has helped the patients he
has been following for coronary artery disease. He reports in his book seeing total
arrest of clinical progression and significant selective reversal of the
disease (Esselstyn,2008)
Although
I fully support a diet rich in vegetables, fruits , legumes and whole grains, I
am concerned by his recommendation to completely remove all fats from the
diet. So I went to chapter 10 of his
book Prevent and Reverse Heart Disease: The Revolutionary , Scientifically
Proven, Nutrition-Based Cure to find out why Heart Healthy oils are bad for
us.
His main point is that olive oil , a monounsaturated “heart healthy” fat, actually
consists of 14-17% saturated fat ( the kind that clogs our arteries). And even though the original studies on the
Mediterranean style diet (which recommends olive oil as being heart healthy) slowed the rate of
progression of coronary artery disease it did not arrest it or reverse its
effects. He goes on to share research
from noted scientists like Colin Campbell, Dr David H Blankenhorn, and Lawrence
Rudel which supports the negative effects of monounsaturated fats like Olive
Oil on coronary artery disease.
What about Omega 3 oils from Salmon,other fatty fish and Flax seed oil?
There
are numerous studies showing the anti-inflammatory effects of omega 3 fats and
even its benefits in coronary artery
disease and heart disease. One study
demonstrated a 29% decrease in heart attacks and death in men who had already
survived one heart attack (Burr,Fehily & Gilbert, 1989). When I went searching his book I discovered
he does allow flax seed oil which does contain omega 3 oils. So his diet isn’t 100% oil free as he stated on the radio today.
What
was not made clear to the listeners of the Kojo Namdi Show was that omega 3
fatty acids(from Salmon or Flax seed) and omega 6 fatty acids ( from Sunflower
oil, Corn Oil etc) are considered essential fatty acids. They are called essential because the human
body cannot create them and therefore they must be consumed. These oils are essential for healthy cell
membranes, vision, the nervous system including the brains, and the immune system.
It was shown early on that patients who couldn't eat and were given Intravenous Nutrition with
only carbohydrates and proteins developed essential fatty acid deficiency
within only 7 – 10 days (Stegink,Freeman, Wispe& Connor , 1977). Some symptoms of essential fatty acid
deficiency include:
- Dry skin (e.g., feet/face/general)
- Scaly or flaky skin (e.g., legs)
- Cracking/peeling fingertips & skin (e.g., heels)
- Lackluster skin
- Small bumps on back of upper arms
- Patchy dullness &/or color variation of skin
- Mixed oily and dry skin ('combination' skin)
- Irregular quilted appearance of skin (e.g., legs)
- Thick or cracked calluses
- Dandruff or cradle cap
- Dry, lackluster, brittle or unruly hair
- Soft, fraying, splitting or brittle fingernails
- Dull nails - lack of surface shine
- Slow growing fingernails
- Dry eyes
- Dry mouth/throat
- Inadequate vaginal lubrication
- Menstrual cramps
- Premenstrual breast pain/tenderness
- Excessive ear wax
- Excessive thirst
- Allergic (e.g., eczema/asthma/hay fever/hives)
- Crave fats/fatty foods
- Stiff or painful joints
Benefits of Essential Fatty Acids in the Diet
Essential
fatty acids play a key role in brain
function. With almost 60% of the brain made up of fat. Deficiencies have also been
linked to neurological impairment ( Hoffman, Johnson & Hatch, 1982). Dietary
oils are also essential for the absorption of fat soluble vitamins like vitamin
A, D, E and K.
Furthermore
a study of 45,000 US men who were followed for 14 years showed a 16% reduction
in risk of coronary heart disease with each 1 gram per day increase in dietary
omega 3 fatty acid intake. And even more
impressive was in those men who ate little or no seafood before the study. They saw a 47% reduction in the risk of coronary heart disease with each 1 gram
per day increase in dietary Omega 3 fatty acids (Mozaffarian , Ascherio , Hu et al, 2005).
I
believe the publicized message that Dr. Esselstyn gave on the Kojo Namdi Show today
was reckless in its ambiguity. His
misleading advice to remove all oils from your diet without clarifying the
importance of supplementing with flaxseed oil added to the current confusion of
what constitutes a healthy diet. It is the responsibility of health
professionals to be clear on the message they are providing. And clear information should not be dependent
on the purchase of a book, especially when the omission of critical information
could lead to severe health complications.

Tomorrow
I will discuss the difference between omega 3 fatty acids from Flaxseed versus
fatty fish like Salmon.

So true sometimes a soundbite is just not enough information. Thanks for filling in the void left behind by the soundbite.
