THE OILING OF AMERICA, A FAT MISTAKE (Updated October 2009)

READER's MANUAL

The bar charts represent the percentages of fatty acids (What is a fatty acid?) in fats and in oils.

The chart bars for saturated fatty acids (list of saturated fatty acids) are blue, the chart bars for monounsaturated fatty acids (list of mono-unsaurated fatty acids) are yellow, the chart bars for polyunsaturated fatty acids from the omega-6 essential fatty acids (n-6 EFAs) (list of omega-6 fatty acids) and the omega-3 essential fatty acids (n-3 EFAs) (list of omega-3 fatty acids) respectively red and green.

The digits at the bottom of the charts represent the number of carbon atoms (the digits before the dot) and the number of double bonds (the digit after the dot) in the fatty acid molecule. The data are from the United States Department of Agriculture (USDA)

 

HUMAN and ANIMAL FAT

Human and animal fat contains saturated (blue) and monounsaturated fatty acids (yellow).

Human and animal fat also contains some polyunsaturated fatty acids (red and green).

 

 

The similarity between human fat, aninal fat and butter is striking.

However the AMA claims animal fat is a health hazard.

How comes eating fat similar to yours can damage your health?

CELL MEMBRANES

The fatty acids we make and the fatty acids we find in food:

1- Become fat molecules

or

2 - Form the bulck of the membranes of all our cells.

Cell membranes are made of a double layer of fatty acids attached two by two

to a phosphoric acid molecule (the yellow spheres in the drawing) forming Phospholipids

-----------------------------------------------------------------------------------------------------------------------------------

FRUIT OILS

Like human and animal fat fruit oils contain mainly monounsaturated (yellow) and saturated fatty acids (blue).

---------------------------------------------------------------------------------------------------------------------------------------------------

VEGETABLE OILS

In Vegetable Oils Trans Fatty Acid is not the Only Threat

Vegetable oils contain much more unsaturated fatty acids than saturated fatty acids and in contrast with human and animal fat where unsaturated fatty acids are predominantly omega-9 fatty acids (yellow bars in the charts), the unsaturated fatty acids in vegetable oils are mainly omega-6 essential fatty acids (n-6 EFAs) (red bars in the charts).

CHANGES IN VEGETABLE OIL CONSUMPTION

One hundred years ago an American was consuming on average 1 pound of vegetable oil per year (1/4 of a teaspoon per day).

Today an american consumes 40 pounds per year (almost 2 fl.Oz per day).

CONSEQUENCES OF THE HUGE VEGETABLE OIL CONSUMPTION

We use EFAs to make prostaglandins . Prostaglandins made from n-6 EFAs increase coagulation, inflammation and immune response while the prostaglandins made from omega-3 EFAs maintain blood fluidity, reduce inflammation and immune response.

For best health our diet should contain both n-6 and n-3 EFAs in a 2 to 1 ratio. Substituting vegetable oils for animal fat and fruit oils has changed the beneficial ratio of 2 to 1 into a disastrous 20 to 1 ratio with among other consequences: undue coagulation, excessive inflammation and an increase of allergic and auto-immune conditions.

THE VERY PARTICULAR CASE OF  CANOLA (rapeseed oil)

Until 1995 Canola oil HAD a favorable omega-6 to omega-3 ratio of 2 to 1. However, since omega-3 fatty acids with their numerous double bonds are very sensitive to degradation by oxidation the producers of Canola oil have selected plants to obtain rapeseeds with a reduced omega-3 content.

This was announced as an improvement of the product’s quality (extension of shelving life and better resistance to high temperature) with no consideration for the health of the consumer. With its actual omega-6 to omega-3 ratio of more than 15 to 1, Canola oil is no better than other vegetable oils. Add to it that it still may contain up to 2% of the pesticide Erucic acid (22.1).

Canola oil is made of rapeseed oil by chemically reducing its content of 30-60 % of erucic acid (22.1) to the legal maximum of 2 %.

See the history of Canola: "the Great Con-ola" by Gally Fallon and Mary G. Enig, PhD.
