Probiotics, the Useful Bacteria

Again, I love to share with the world the latest healthy information I’ve got from Dr. D’Adamo’s newsletter sent to me. I believe this very fresh information would benefit your healthy life.

Do you know that there are 20 times more bacteria than cells in your body, or that you have more bacteria in your body at this very moment than the total number of people who have ever lived on the planet? This may sound alarming, but these tiny organisms are crucial to good health.

What is Probiotic

A probiotic is an organism which contributes to the health and balance of the intestinal tract.These “friendly” or “beneficial” bacteria live in your small and large intestines, support your immune system, and contribute to healthy digestion.

A number of companies have recognized the importance of these friendly bacteria and are supplementing their yogurt products with probiotics. Turn on the TV during the traditional mid-morning and afternoon programming hours aimed at women, and you’ll be invited to take the “challenge” that one company is offering—your money back if you don’t see improvement in digestion after one month. While it’s great that people are becoming more aware of how these good bacteria contribute to digestion, they don’t mention that specific strains of bacteria are beneficial or harmful in the gut of people with different blood types.

What does blood type have to do with friendly bacteria? According to Dr. D’Adamo, there are three things:

  • Your blood type antigens are prominent in your digestive tract and in about 80% of individuals (secretors), are also prominent in the mucus that lines your digestive tract. Because of this, many of the bacteria in your digestive tract actually use your blood type as a preferred food supply. In fact, blood group specificity is common among intestinal bacteria with almost 1/2 of strains tested showing some blood type A, B, or O specificity. To give you an idea of the magnitude of the blood type influence on intestinal microflora, it has been estimated that someone with blood type B will have up to 50,000 times more of some strains of friendly bacteria than either blood type A or O individuals.
  • Some strains of beneficial bacteria can have lectin-like hemagglutinin activity directed against your blood type, so avoiding those is a good idea.
  • Polyflora Blood Type Specific Probiotics also blend prebiotics (foods which provide special growth factors for probiotic bacteria) that are right for each blood type.

In a recent blog, Dr. D’Adamo referenced two recent studies that link type II diabetes, obesity, and the lack of intestinal flora. He says, “Increasingly, studies are showing that changes in the microflora content of the digestive tract can be linked to metabolic illnesses, including type II (adult onset) diabetes and obesity. Blood group and secretor status play an important role in conditioning the overall characteristics of the digestive tract, including influencing the appearance and frequency of many strains of bacteria.”

Routinely taking probiotics that are Right for Your Type improves digestion, enhances bioavailability, promotes detoxification and better absorption of nutrients, and enhances immunity. There is also evidence that routine use of probiotics lowers LDL (bad cholesterol), inhibits Candida (yeast), and may even prevent nitrates from being converted into cancer causing nitrosamines.

As a point of interest, the word probiotic means, “in favor of life.” I’m in favor of that!
