The Living Force
In the past year, I've become acquainted with a new food called Lard - well new to me anyways. As most children of my age raised in the US, my parent's made sure I was getting the healthiest fat possible - that being margarine. I remember my parents regarding lard as something of a poor man's food and TOTALLY unhealthy due to it's high cholesterol and saturated fat content. So you can imagine my surprise when I started reading that lard as in pig fat may actually be GOOD for you.
In my search to peal away dietary disinformation, I came across lard as a source of cooking fat/oil in Sally Fallon's book, Nourishing Traditions (_http://www.amazon.com/Nourishing-Traditions-Challenges-Politically-Dictocrats/dp/0967089735). This book is listed as a "cookbook" on the cover, but it goes far beyond just recipes and dives into serious research on the subject of health. One of the big points she makes is that the way we procure our food from the source of raw ingredients to the method of preparation can make a HUGE difference in the nutritional quality of the food. Things like soaking grains, flours, fermenting vegetables and dairy, heat of cooking, etc. She explains why certain steps are necessary in the food preparation process and backs it up with a lot of research. The book is highly recommended for those who want to cut through the dietary disinformation promoted by the "diet dictocrats" as she calls them or as the "pathocracy" as they're generally known here.
Her exposition of Fats and Cholesterol in the book's introduction is one of the most comprehensive discussion of the subject I've come across in recent years. If anybody is interested I can transcribe this 20-page or so section when I get the time. The basic point to understand here is that saturated fats and cholesterol are not the pair of evil villains that modern dieting gurus make them out to be. Here is what she has to say about lard under this section:
[quote author=Nourishing Traditions]Lard or pork fat is about 40 percent saturated , 48 percent monounsaturated (including small amounts of antimicrobial palmitoleic acid) and 12 percent polyunsaturated. Like the fat of birds, the amount of omega-6 and omega-3 fatty acids in lard will vary according to the diet of the pigs. In the tropics, lard may also be a source of lauric acid if the pigs have eaten coconuts. Like duck and goose fat, lard is stable and a preferred fat for frying. It was widely used in America at the turn of the century. It is an excellent source of vitamin D, especially in the third-world countries where other animal foods are likely to be expensive. Some researchers believe that pork products should be avoided because they may contribute to cancer. Others suggest that only pork meat presents a problem and that pig fat in the form of lard is safe and healthy.[/quote]
The vitamin D line caught my attention, especially with all of the recent research on the health benefits of vitamin D as promoted by Dr. Mercola and others. From the perspective of living in a northern, temperate climate, there are few sources of fat or oil in this neck of the woods. We can't grow olive trees or find plentiful supplies of fish or whales. 4-legged animals have traditionally filled the role of fat production in this part of the world and in particular pigs as mentioned by Fallon. She also mentions that lard and all saturated fats in general have anti-microbial properties, especially for the intestines. Could it be that the increase in chronic stomach diseases and general lack of immunity from infectious diseases be partially due to the removal of lard from the diet? The lack of saturated fats would lessen the immunity of the stomach and the lack of vitamin D would lessen the overall immunity of the body, at least this seems logical to me if the research is correct.
I'm a regular reader of Dr. Mercola, so I'm aware of his promotion of Vitamin D. He claims that getting vitamin D from sunlight is the best way and that taking Vitamin D orally should be your last resort. Well that might be fine in an ideal world where we get all the free time to frolic in the sunlight for hours or at the least stand naked for periods of time in front of high energy lamps. Not only this, but to actually absorb this vitamin D from sunlight, one must bathe in a very specific way not to use soap on of the sun exposed skin! (_http://articles.mercola.com/sites/articles/archive/2009/05/12/Shocking-Update-Sunshine-Can-Actually-Decrease-Your-Vitamin-D-Levels.aspx) I'm sorry, but this seems a bit much to me. Personally I would rather have animals do this work for me and then ingest those substances such as Vitamin D from them if that is possible. It seems a little more efficient.
Now, believe it or not, it's actually hard to come across a valid number of how much Vitamin D is in a given amount of lard. The USDA seems to have somehow erased this data from it's website (_http://forum.lowcarber.org/showthread.php?t=297375). Here is what it says on the Weston Price foundation website:
_http://www.westonaprice.org/basicnutrition/vitamindmiracle.html
[quote author=Weston Price Foundation]Food Sources of Vitamin D
USDA databases compiled in the 1980s list the following foods as rich in vitamin D. The amounts given are for 100 grams or about 3 1/2 ounces. These figures demonstrate the difficulty in obtaining 4,000 IU vitamin D per day from ordinary foods in the American diet. Three servings of herring, oysters, catfish, mackerel or sardines plus generous amounts of butter, egg yolk, lard or bacon fat and 2 teaspoons cod liver oil (500 iu per teaspoon) yield about 4,000 IU vitamin D-a very rich diet indeed!
[/quote]
Since these numbers come from portions of 100g. For lard, this equals about 1/2 cup or so. Based on the latest research, they now suggest about 4000IU of Vitamin D per day for an average individual. This means one would have to eat about 1 1/2 cup of lard per day to get the right dosage. That might seem a little unreasonable, even for people who regularly consume lard. I have an old-timer neighbor who tells me stories about what life was life while he was growing up in these parts. He talks about how his mother would pack him a lard sandwich for school. This was basically two pieces of bread generously slathered with lard in the middle. If the bread pieces are of average loaf size, then one is probably looking at 1/4 to 1/3 cup of lard, still not the recommended dosage, but it's probably more than the average person gets in their diet today. Not to mention people generally spent more time outdoors in those days as well, which might make up the difference (assuming they didn't shower with soap!).
Speaking of soap, lard used to be the main fat used in soap making around this same period. One would have to conduct studies to see if any of the vitamin D from the soap would pass through the skin during the process of bathing. It could be that the saponification process with the lye destroys the vitamin D, I don't have enough background in chemistry to know. Who knows, maybe soap residue of this kind might actually be healthy for you?
Vitamin D itself is actually quite stable and cooking it or freezing it will not destroy it's chemical structure, so it should be possible to use the lard in a wide variety of frying and backing applications and still derive the benefits from it's vitamin D content.
I also found this somewhat interesting:

[quote author=Dr Mercola]
If You Take Oral Vitamin D, Make Sure You Take the Right Kind
There is one other thing you need to be aware of if you choose to use an oral vitamin D supplement and that is that there are basically two types. The natural one is D3 (cholecalciferol), which is the same vitamin D your body makes when exposed to sunshine.
The synthetic one is vitamin D2, which is sometimes called ergocalciferol.
Once either form of the vitamin is in your body, it needs to be converted to a more active form. Vitamin D3 is converted 500 percent faster than vitamin D2.
Interestingly, it was previously thought that the kidney exclusively performed this function; at least that is what I was taught in medical school.
However, in 1998 Dr. Michael Holick, the person who discovered activated vitamin D, showed that many other cells in your body can make this conversion, but they use it themselves, and it is only the kidney that makes enough to distribute to the rest of your body.
[/quote]
I don't know if this a real connection or just a coincidence, but he mentions that Dr. Michael Holick's findings about how the kidney's are responsible for distributing adequate doses of vitamin D to the rest of the body. Well, it just so happens that the best source of fat from the pig (as claimed by chefs and others) comes from the area around it's kidney. This is also known as the "leaf fat".
_http://en.wikipedia.org/wiki/Lard
[quote author=Wikipedia]Lard can be obtained from any part of the pig as long as there is a high concentration of fatty tissue. The highest grade of lard, known as leaf lard, is obtained from the "flare" fat deposit surrounding the kidneys and inside the loin. Leaf lard has little pork flavor, making it ideal for use in baked goods, where it is treasured for its ability to produce flaky, moist pie crusts. The next highest grade of lard is obtained from fatback, the hard fat between the back skin and flesh of the pig. The lowest grade (for purposes of rendering into lard) is obtained from the soft caul fat surrounding digestive organs, such as small intestines, though caul fat is often used directly as a wrapping for roasting lean meats or in the manufacture of pâtés.[/quote]
Perhaps, if the pig's physiology is anything like our own, then the pig's kidney also acts as the distributor of vitamin D to the rest of its body. Since vitamin D tends to accumulate in fat, perhaps the fat surrounding the kidneys is first to get saturated with vitamin D before getting to the rest of the pig's body. This would logically make it a higher source of vitamin D assuming vitamin D has to travel through this area first to get to the rest of the pigs body. I'm not sure if this comparison is useful, but I found it interesting. Perhaps to make the best use of the vitamin D we ingest or absorb, we also need to have fairly well functioning kidneys too?
Now, don't just run out to your local supermarket and pick up a bucket of lard! From the same Wikipedia section:
[quote author=Wikipedia]Industrially-produced lard, including much of the lard sold in supermarkets,[citation needed] is rendered from a mixture of high and low quality fat sources from throughout the pig.[8] It is typically hydrogenated[citation needed] (which produces trans fats as a by-product), and often treated with bleaching and deodorizing agents, emulsifiers, and antioxidants, such as BHT.[4][9] Such treatment makes lard shelf stable. (Untreated lard must be refrigerated or frozen to prevent rancidity.)[/quote]
So it may help to find a source of pig fat that you can trust. Recall that fat also accumulates a number of fat soluble toxins (such as PCBs, BPA and other fine petrochemicals), so if the pigs were fed a poor diet, then the chances are their fat will be less than health promoting. If you are interested in trying out lard, try to find a good source first. Rendering lard yourself is not too difficult, or so I'm told. The farmer I purchase mine from does his own rendering which he claims amounts to putting the lard chunks through a meat grinder and then cooking them on a VERY low heat for a 12 hour period or so. This can then be poured off in jars and refrigerated.
