In this issue of the newsletter, we wrap up our series on the cardiovascular system as we explore blood types and blood tests.
Once again, the goal is not to help you graduate medical school, but to help you learn enough so that you are not clueless in your doctor's office and understand the options particularly the non-medical ones that are available to you. Specifically you're going to learn about:. At face value, blood type probably is not that important to you. Its value is primarily to doctors when doing transfusions.
But if you scratch below the surface, an exploration of blood type reveals a great deal about the nature of blood and the human organism in general. It also, thanks to the popular blood type diet program, serves as a launching point for a discussion of the proper human diet.
With that in mind…. There are two primary systems for classifying blood type: They are similar, just governed by different antigens. Your blood type is inherited from your parents. You receive one gene from your mother and one from your father, which combine to establish your blood type. These two genes determine type by causing certain molecules such as sugars, proteins and glycoproteins a combination learn more here both sugars and proteins to appear on the surface of your blood cells.
The genes also cause defenders that protect against similar but not identical antigens to appear in your plasma. These defenders are known as antibodies. But the antibodies Type My Health Blog your plasma will treat non-identical glycoproteins as allergens and Type My Health Blog the blood, causing the cells to clump together —thus the need to match blood types when getting a transfusion.
Let's explore this concept further. People are divided by blood type into one of four categories: A, B, AB, and O. People with type A blood have the A antigen, while people with type B blood have surprise the B surface antigen.

Those with continue reading type AB have both antigens, and type O blood types have no antigens on their surface. Someone with type A blood, for example, will reject a type B blood transfusion because the antibodies in their blood will recognize that the antigens attached to the donated blood are outsiders—not part of the "self.
For more detailed information on ABO blood types and just click for source they get inherited, check out Wikipedia. The Rhesus system is the second significant blood group system used in human blood transfusion. Of the different Rhesus antigens found on the surface of blood cells, the primary one is the RhD antigen because it is the most likely to stimulate an immune response in the body.
The name Type My Health Blog comes from the type monkey that was used in the Type My Health Blog studies that identified this factor. When the Rhesus antigen is present, the blood group is described as positive.
When it's absent, the blood group is described as Type My Health Blog. In other words, you either have, or do not have, the Rhesus factor on the surface of your red blood cells. This means that every ABO blood type has a corresponding positive or negative Rhesus suffix attached, as in:. Problems with transfusions are more likely to occur with mismatches in the ABO system than the Rhesus system. If you are exposed to a blood group antigen that is not recognized as belonging in your body, http://uht.me/essay-help/a-good-thesis-statement-for-pro-life.php antibodies in your blood plasma will bind to those blood cells causing them to clump together and die.
A different problem can occur in pregnant women. A certain amount of donated blood is actually separated into pieces fractionated in order to maximize its benefits and extend shelf life. So why are we talking about diet in the middle of a discussion about blood? Well, a couple of reasons.
First, people want to know. We receive several dozen questions a month at the Foundation asking what we think of the blood type diet. But more importantly, in answering questions about the diet, we get to explore some of the evolutionary history of blood—which can be very helpful when it comes both to understanding it and optimizing it.
The premise behind the blood type diet combines the principles of the ABO groupings explained above and the evolutionary theory of blood groups first proposed in the 's. The basic idea is that blood types evolved from the lifestyles and diets of different groups of humanity; therefore, you need to eat the diet natural to the group of humanity from which you are descended.
Perhaps, not so much. First, it's important to remember that the evolutionary theory of blood groups is only a theory that is unlikely to stand the test of time. It turns out that environmental factors probably play a much bigger role in the evolution of blood types and also explain why certain types Type My Health Blog concentrated in certain geographical areas.
Nature is filled with trade offs. A person with lots of body fat has insulation in cold latitudes, but sweats unbearably in the tropics. A large muscular person is stronger, better able to fight and conquer, but also requires many more calories to maintain themselves than a smaller person.

By going on a paleo diet whether cooked paleo diet or better yet raw paleo diet plus eating some raw bitter melon every day will give you the nutrition you need to. Want to know more about eating for your blood type? This article shows what foods are good to eat on a blood type diet for blood type A. Which Type of Bread Is Healthiest? (and the type of grains you choose, in general) can help you take great strides on your journey to health. A few months ago my Bob Beck type magnetic pulser arrived. I’m not yet too adept at using it, but what I do know is it has the power to make stuck up things be.
The same traits have advantages and disadvantages depending upon the circumstances, and so with blood types. Each type is protective against certain diseases and conducive to others. As we've already discussed, blood types are genetically inherited, but the environment can influence which blood types are passed on. An example is seen with the Black Plague, which killed millions of people in Europe in the 13th and 14th centuries.
As it turns out, the Black Plague was caused by a bacterium that is covered by sugar molecules that closely resemble the B marker on red cells.
That means that since people who were blood type B back in the plague years didn't make antibodies to that antigen, they didn't have any antibodies in place to protect them against the plague. Hence they died in greater numbers than the other blood types which carried the antibodies. And, in fact, by the 15th century, fatalities from the plague had decreased significantly as type B blood was systematically phased out in that part of the world.
The bottom line is that the distribution of blood types in Europe low percentages of Type B as opposed to Asia is not so much the result of diet and occupation, but of natural selection based on disease. For example, people with type O blood are susceptible Type My Health Blog certain bacteria and viruses that can cause diarrhea and ulcers, but have a decreased susceptibility to SARs.
With that in mind, we would expect to see, based on natural selection, a greater concentration of type O blood in Asia, where respiratory diseases such as SARs tend to be more common, than in Europe.
And, indeed, such is the case. As you can see, a particular blood type may predispose you to one disease while simultaneously protecting you click here another. Variation in the blood type distribution throughout the world reflects these environmental factors coupled with the tendency of populations to marry and reproduce Type My Health Blog their own groups.
As people throughout the world intermingle to a greater extent, the distribution of the different blood types is likely to become more uniform throughout the world. This premise does not actually require the evolutionary theory to be correct to work. Even if the theory is wrong, the effect can be true. Yes, there is no question that different foods definitely have high allergy potential for many people, but the problem appears to be less with the lectins, than with the ability of the digestive tract to fully break down the proteins in the food.
As I've discussed in several newslettersthe use of digestive enzymes with meals and proteolytic enzymes between meals can often help reduce food allergies dramatically. In fact, there is little evidence that lectins, other than a handful of exceptions such as ricinpresent a problem for the human body of any blood type. Simple math works in its favor. If you tell an O, an A, or an AB not to eat dairy because they don't have the right blood type, then you've just told the vast majority of people in the world not to eat dairy.
Considering all of the problems associated with homogenized, pasteurized, commercial dairya whole lot of people are going to feel significantly better on the diet…regardless of blood type.
Chalk that up in the win column for the diet. On the other hand, you've also just told a lot of Asians they have the highest percentage of type B's in the world that they'll thrive on dairy. And that would need to be chalked up in the loss column. Anyway, I've detailed my feelings that diet should be based on comparing the teeth, stomachs, and digestive tracts of humans to other animals in Chapter 6 of Lessons from the Miracle Doctors.
That kind of comparison will give Type My Health Blog a more accurate make that more objective read on what the body was actually designed to eat. You can download a free copy at www.
WHAT I EAT IN A DAY
But enough on the blood type diet. Let's get back to the issue at hand: More specifically, let's talk about blood tests—how to understand them and what they mean to you. Blood tests are the number one tool doctors use to understand the state of your health.
Since blood flows throughout your entire body, it picks up bits and pieces of everything and gives clues not only to its own condition, but to the presence of disease in organs such as the liver, kidneys, thyroid, pancreas, and endocrine system. Since blood tests are so wide ranging, I'm going to limit my discussion in this newsletter to those tests that impact the cardiovascular system itself.
We'll save discussion of enzyme tests for the liver and creatinine tests for the kidneys, and all of the other organ specific tests for later newsletters when we actually focus on those organs and systems.
Before we look at some of these tests in detail, it is important to realize that results can fall outside the Type My Health Blog range" for many reasons that have nothing to do with illness. Age, race, sex, diet, level of exercise, supplements, drugs, etc. In other words, the definition of what is normal is somewhat arbitrary.
Since a normal blood workup will usually include tests, falling outside the range on one or two of them does not necessarily indicate a problem—unless other factors are present.
It's also worth noting that the "normal range" is now being "redefined" by the blood test results of ever increasing numbers of people who eat badly, don't exercise, and are actually very unhealthy. When you consider that sperm counts have dropped by more than half in the last 50 years, falling outside the norm on many tests may not be such a bad thing. Let's now take a look at some of the blood tests your doctor runs.
I'm not going to give numbers for the most part since they would just be information overload at this time. Instead, I'll just talk about what high here low numbers might mean. It will be easy enough for you to see where your numbers fall when you get your results back from your doctor. There are actually many tests that can be performed as part of a CBC.
In most cases, they should all be done after fasting for at Type My Health Blog 12 hours. The most important are:. Albumin Type My Health Blog Globulin tests measure the amount and type of protein in your blood. They are a general index of overall health and nutrition. Low gamma globulin levels are seen in people who donate blood too often or have immune system problems.
