On Butter and Margarine

I use Extra Virgin Olive Oil in the majority of my cooking. It is the universally accepted, heart healthy fat because of its unique monounsaturated nature. It has anticancer properties and has been shown to support clean arteries. It is even metabolized more like a carbohydrate than a lipid. EVOO is good.

But, if you notice from my posted recipes, I also use butter in moderation. Why would I use butter?

Butter has been falsely accused as a lethal saturated fat. Let's take a closer look. Is it the same as the saturated fats found in meat products? There is a big difference between the short chain fatty acids found in butter and the longer chained fatty acids found in the layers of fat surrounding red meat. The short chain fatty acids found in butter are metabolized and used for energy similar to a carbohydrate. The longer chained fatty acids from feedlot meats are unused and stored away, leading to plaque buildup in the arteries.

For a very interesting look at 20 Health Benefits of Butter, take a look at this site. If you have previously thought butter was a villain, you might want to go through all the documented sources on this page... very thought-provoking reading.

But what about margarine? A study conducted in 1995 at Harvard Medical School showed that heart patients who consumed margarine were twice as likely to have a heart attack than those who consumed butter. Hmmm... why is this study so unheard of? Margarine has been shown to cause arterial disease and it has also been implicated as a carcinogen. While margarine may look a lot like butter, don't be fooled. The restructuring of vegetables oils (hydrogenation) forms a toxin, not a food. Our bodies may deal with it as best they can -- we have amazing defense mechanisms -- but the toxic effect leaves its scar over time.

While I avoid ALL hydrogenated oils, I also avoid polyunsaturated vegetable oils (canola, corn, soybean) because they must be highly processed in order to be marketable. This processing leaves the oils unstable and rancid, unsuitable for consumption. I think it is best to stick to cold pressed olive oil, short chain fats (like butter) in moderation, and fats found in natural foods such as avocados and nuts.

So, again, on this "healthy fats" topic, I have only scratched the surface. Here are a few further research recommendations:
