What is Spam anyway?
I saw a recent article in the business section of my local newspaper
stating that the production and sale of Hormel’s meat product, SPAM, has had double digit growth over the last few months
beginning in May of 2008. This corresponds to the downward trend in the overall economy with folks looking for ways to reduce
expenses. It seems that with every downward cycle of the economy, SPAM sales increase. I don’t eat SPAM myself and the
culinary attraction is not there but I understand saving money, which is, I assume, part of the appeal in the product. It’s
cheap ($2.60 per can) and plentiful. So I thought I’d review what’s in SPAM and see if I could get any nutritional
value for my hard earned money.
First some historical
tidbits; SPAM, aka Mystery Meat and Something Posing As Meat, has been around since the 1930’s when it was called Hormel
Spiced Ham. The name was shortened to SPAM and has been in continuous production ever since. During World War II, because of meat rationing and difficulty getting fresh meat overseas,
SPAM was used extensively to feed the troops. It became a staple then in post-war Europe and Asia where it still maintains
somewhat of a cultural following. It is so ubiquitous in Asia that it is served in those bastions of epicurean delights, McDonalds
and Burger King. In parts of England you can purchase spam fritters and chips instead of fish and chips. While the main Hormel
production site is in Austin, Minnesota, it has been licensed for production in both Europe and Asia. Annually, 122 million
cans are sold worldwide. In the US, Hawaii is the biggest consumer. Nutritionally, 1 serving or 2 ounces of SPAM contains 7 grams of protein, 2 grams of carbohydrates, 15 grams of fat
of which 6 grams are saturated fats, and 170 + calories. A serving of spam also contains 767 mg of sodium. This is about 3.5%
of the total weight of the serving in salt. There is minimal vitamin content in SPAM with no “A”, a little “C”
along with some calcium and iron. The label ingredients in SPAM are: chopped pork shoulder meat, ham meat (what part does
ham meat come from?), salt, water, sugar and sodium nitrite as a preservative. There is a gelatinous covering on SPAM which
is called aspic. Aspic forms from the gelatin found in the meat after processing.
Taking a look at a canned chicken
product from Swanson, 2 oz packed in water, we have 50 calories, ½ gram saturated fat, 270 mg of sodium, 10 gram of
protein and 1 gram of carbohydrate. Again there is no appreciable vitamin or mineral content. Oh, and there is no aspic.
So there you have it; a high sodium, high calorie,
high saturated fat pork product with a jelly coating versus a significantly healthier chicken product of comparable cost.
In this economy I think my nutrition dollar goes further with the chicken. Even better, buy a whole chicken and forget the
cans. You’ll probably save some money besides.

EPA/DHA in the news
Omega 3’s, the “good fats”, are in the news again. Omega 3’s, primarily eicosapentanoic acid
(EPA) and docosahexanoic acid (DHA) are involved in supporting a vast number of body systems including heart, brain, nerve,
skin, immune and blood vessel health. Without these fats the systems will not function at optimal health.
In a study recently published (AJCN, Feb 2009), EPA may help alleviate depressive
symptoms in peri-menopausal women. Women with mild to severe depression were given a little more than 1 gram of EPA or a placebo
for 8 weeks. The women classified as mild to moderately depressed received significant benefit from the EPA whereas the women
classified as severely depressed did not benefit. We obtain EPA and DHA from our food,
including fish and algae, but our bodies can also make some EPA using a precursor fat called alpha-linolenic acid (LNA). Because
this pathway is somewhat inefficient, only about 2-6% of the LNA consumed is converted to EPA. In addition people are eating
less fish over concerns about heavy metal contamination. Our consumption of EPA/DHA is, therefore, below what it should be.
It makes sense then to supplement EPA and DHA fats in our diet with fish oils. Many
fish oils have the added benefit of containing vitamin “D”. A recent study (Arc Int Med, Feb 2009) says that “D”
can help reduce the risk of cold and flu. Another study (J Ger Psy & Neur, Dec 2008))
demonstrated that reduced “D” levels are associated with cognitive impairment and dementia. The basic supplements I recommend to all my patients include fish oil with vitamin D, a whole food multiple and
a probiotic. An 8 ounce bottle of fish oil prevention makes sense.

How much omega 3 fats do you need?
Dr Bruce Holub, an expert on omega 3's in North American diets, says we currently obtain about 135 mg per day of
EPA and DHA, the two most important of the omega 3 good fats. In his review of the scientific research Dr.
Holub found that those people who consumed an average of 2 fatty fish meals per week obtained about a 40-50% lower risk
of developing specific heart health issues. This is the equivalent of 250-300 mg/day average of EPA/DHA. The
Food and Drug Administration has also indicated that, while not conclusive, EPA/DHA may help reduce the risk of coronary heart
disease. 1 teaspoon of a quality fish oil like Olde World Icelandic will give you the equivalent of
585
mg/day of EPA/DHA. This oil will also provide significant levels of vitamin "A" and vitamin "D". So include
a fish oil into your daily supplement regimen along with a probiotic and a whole food multiple. Your health will thank you.
