Alert: This Very Popular Medication is Backfiring

It’s one of the most prescribed types of medications over the past 30 years…

In fact, it’s been excessively over-prescribed, and now even the Centers for Disease Control is saying it’s a public health issue.The medication is antibiotics, and if you’ve gone to the doctor in the last three decades, chances are very high they’ve been prescribed to you, too.

The problem, in summary, is three-fold:

  1. Antibiotics mean anti-bacteria, but not everything that makes you sick is bacteria. For example, a lot of what makes you sick are viruses.
  2. Antibiotics don’t just attack the “bad” bacteria in your body, they also attack the good bacteria you need to be healthy (which is why, if you’ve even taken antibiotics in your youth to the present, you definitely need good probiotics!)
  3. Antibiotics have been so overused that bad bacteria have grown resistant to them.

Don’t miss this important article to discover the essentials you really need to know.

And once you’ve read it, please be sure to share this particular article with family and friends too, so they are aware.


Polyflora Probiotics

Although Dr. Peter D’Adamo first wrote about the effects of blood type on the intestinal bacteria flora (the microbiome) over two decades ago, recent advances in genomic technology have thrown an entirely new light on this important relationship. New findings have associated poor regulation and balance of the gut flora (a syndrome called ‘dysbiosis’) with a long list of human health problems, including poor metabolism, lack of mental clarity and focus, poor adaptation to stress and many other ailments of modern living. It appears that keeping our internal flora happy, balanced and properly nourished is essential to having a high-functioning lifestyle.

Probiotics and Prebiotics


More and more, we hear and read about the importance of the microbiome, the ecological community of friendly and unfriendly microorganisms that share our body space. The human body contains over 10 times more microbial cells than human cells, and increasingly changes to the microbiome are being associated with alterations, both good and bad, to our health.

Probiotics are microorganisms that are believed to provide health benefits when consumed. The probiotic concept was first advanced by the Nobel Prize recipient Élie Metchnikoff, who in 1907 suggested “the dependence of the intestinal microbes on the food makes it possible to adopt measures to modify the flora in our bodies and to replace the harmful microbes by useful microbes.” Common benefits of probiotics include the decrease of potentially problematic microorganisms, the reduction of digestive discomfort, enhancement of the immune system, improvement of the skin’s function, and the improvement of bowel regularity.


In diet, prebiotics are typically non-digestible fiber compounds found in foods that can pass undigested through the gastrointestinal tract and stimulate the growth and activity of friendly bacteria that colonize the large bowel by acting as nutrients for their development. These friendly flora then contribute to the well-being of their host. Preliminary research has demonstrated potential effects on calcium and other mineral absorption, immune system effectiveness, and intestinal regularity. Evidence suggests that the effects of prebiotics result from increased production of short-chain fatty acids (SCFA) by the stimulated beneficial bacteria. SCFAs are known to have a multitude of beneficial effects on the digestive tract.


Friendly bacteria work better when more of them are combined together. There are actually hundreds of strains of bacteria in your digestive system and the friendly bacteria actually operate as a team, promoting the beneficial effects of each other. The term synergism best describes the interrelationship of friendly bacteria. They mutually support each other by producing chemical signals that they are resistant to, but which decrease the amount of un-friendly (problematic) bacteria. In fact, these chemical signals (known as ‘bacteriocidins’) are up to 1000x more active when various strains are combined than when they are used isolated. Even more importantly, the health effects of one strain of friendly bacteria are often not duplicated by other strains. Therefore, a more complex mixture, combining more friendly strains of bacteria, translates into enhanced long-term health benefits.

Blood Types and Probiotics

There is surprising evidence that many of the bacteria in your microbiome like to ‘eat right for their blood type.’ Our blood type antigens are actually prominent in your digestive tract and, in about 80% of individuals (secretors), are 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 50% of strains tested showing some blood type A, B, or O specificity. Polyflora blood type specific probiotic formulas are unique in that they blend blood type specific prebiotics –foods which provide special growth factors for probiotic bacteria– right into the probiotic formula, using foods rated ‘beneficial’ for each blood type.

Human feces contain enzymes produced by the bacteria of the microbiome that degrade (digest) the ABO blood type antigens that line your digestive tract. There is good evidence that the ABO blood type and secretor status are a major influence on the specificity of these bacterial enzymes produced the microbiome. The population of fecal bacteria that produce blood group-degrading enzymes is highly correlated with the ABO  and secretor type of the host: 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.

So why take unnecessary chances? Maximize your friendly-flora potential by choosing a probiotic formula that right for your type.

The Truth About Cholesterol Levels & Cancer Most MDs Don’t Know

By Dr. Jack Wolfson

Cholesterol is one of the most important molecules in your body. Often vilified by mainstream medical doctors and the media, cholesterol serves many functions including: cell membrane integrity and function; production of vitamin D; digestion (it is a large component of bile); the precursor to hormones such as testosterone, estrogen, progesterone, and cortisol.

Cholesterol is so important that every animal and every fish make it as well. Why do eggs contain cholesterol? Try forming a chicken without it!

I have written extensively on cholesterol, that is why I dedicated the first chapter of my book, “The Paleo Cardiologist” to this subject. As a cardiologist, I have listened to the anti-cholesterol rhetoric from medical doctors and the media for years. This is all Big Pharma propaganda to sell us drugs. These drugs lower cholesterol down, but do very little, if anything, for outcomes that matter such as heart attacks, stroke, and dying.

Is There Such a Thing As a Perfect Cholesterol Level?

The truth is that total cholesterol has very little to do with living and dying. Studies confirm that between 160 and 260, there is very little difference is mortality. My goal is to find the perfect cholesterol level for each patient as an individual. Your perfect cholesterol level is different from your best friend, your spouse, and your neighbor. You can follow the tenets in “The Paleo Cardiologist” to achieve the best cholesterol for your body’s needs (more on that below).

Quickly, LDL has been considered the “bad” cholesterol and HDL the “good” cholesterol. But this version of the story is false. Humans and animals alike make LDL and HDL for a reason. Both serve the immune system and transport vital nutrients (like cholesterol and fat soluble vitamins) for a reason.

The Link Between Cholesterol and Cancer

Let’s take a look at the data demonstrating that higher cholesterol confers a lower risk of cancer…

Prostate Cancer – Patients undergoing radiation and prostatectomy fare better with higher levels of LDL. Those with the highest LDL had a 33% less cancer recurrence compared to those with the lowest LDL levels.1

Lung Cancer – A recent study found those with lung cancer and the highest cholesterol levels had a 67% lower risk of dying.2

Breast Cancer – Women with the highest cholesterol levels had the lowest risk of breast cancer. In fact, the number was 30% lower. The same study found women had a 39% lower risk of melanoma and a 39% lower risk of lymphoma/leukemia when their cholesterol levels were the highest.3

Pancreatic Cancer – Men with the highest cholesterol had a 48% lower risk of pancreatic cancer along with a 33% lower risk of non-melanoma skin cancer, 86% lower risk of liver/gall bladder cancer, and a 32% lower risk of lymphoma and leukemia.4

Colorectal Cancer – Studies suggest that those with higher cholesterol levels are protected from colorectal cancer versus those with lower levels.5

Find Your Perfect Cholesterol Level (and Lower Your Cancer Risk)

Total cholesterol as a measurement is so 1970s. If your doctor is measuring this, ask for advanced lipid testing. This would include LDL particles and HDL particles. You need to know the number of particles and the size of the particles. These measurements are so much more relevant than total cholesterol, total LDL and total HDL. In fact, the ratio of LDL particles to HDL particles is the best prognosticator of all lipid parameters.

Remember, we cannot live without cholesterol and this fact is not surprising given all the functions it serves. LDL and HDL each have a unique purpose in the body. We encourage everyone to find their perfect cholesterol and perfect lipids numbers.

Here is a Top 10 list to achieve perfect cholesterol numbers for YOU:

  1. Eat organic Paleo foods (real, whole foods). It worked for our ancestors, it will work for you. Cholesterol in food does not increase heart disease risk, why would it increase cancer risk? Organic gatherer food and pasture-raised hunter food.
  2. Get sleep. Lipids such as cholesterol are made while we sleep. For thousands of years, we went to sleep with the sundown and awoke with the sunrise.
  3. Get sunshine. The sun converts cholesterol into vitamin D. Lack of sunshine equals excess cholesterol production. When we weren’t sleeping, we were in the sun. More sun equals more vitamin D equals lower cancer risk.
  4. Get exercise. Physical activity keeps lipids in check. Physical activity lowers cancer risk.6
  5. Get adjusted. Your local chiropractor fixes more than back pain. By correcting spinal subluxations, autonomic nervous system balance is achieved. This leads to excellent organ function.
  6. Get hydrated. Drinking quality water ensures that your cells are bathing in health. Water molecules make up over 99% of the molecules in the body.
  7. Get grounded. Harness the energy from the earth to charge the body. Good things happen to those that walk/stand barefoot.
  8. Get away from environmental pollutants. Toxins and heavy metals lead to inflammation and inflammation leads to excess lipid production. Clean air, clean water, clean food, and a clean environment.
  9. Get evidence-based supplements. Some of my favorites include spirulina, garlic, and berberine but nothing is more important than probiotics. Read about bergamot as well.
  10. Get advanced testing. Total cholesterol is “old school” medicine. You need to know LDL and HDL particle number and size.

What About Pharmaceuticals?

Corporate America loves to promote better living through chemistry. To be candid, there is literature supporting drugs such as aspirin and statins lowering cancer risk. But do humans get cancer because of a pharmaceutical deficiency? Obviously not. Cancer has a cause. Heart disease has a cause. Find the cause and you will have the cure.

Diabetes, Kidney Disease, and Magnesium Supplementation

Globally, as of 2015, the International Diabetes Federation, reported an estimated 415 million adults are living with diabetes. Yes, that’s more than the population of the U.S. The incidence of diabetes is increasing rapidly, and by 2030, this number will likely double.

Many people live with type 2 diabetes for a long period of time without being aware of their condition. By the time they figure it out the complications of this condition may already be present.

One of the signs of diabetes is low magnesium; it’s in all the medical texts but because doctors never learned about the importance of minerals in medical school, they do not routinely test for magnesium. And if they do, they use the wrong test. The serum magnesium test is highly inaccurate.

You want to have an optimum magnesium level of 6.0-6.5mg/dL.

Diabetes damages the kidneys and is the leading cause of kidney disease. However, when the kidneys are impaired, doctors tell their patients not to take magnesium, which is what they actually need to heal their kidneys. Dr. Carolyn Dean has written articles and blogs about the need for magnesium in kidney disease and is in the process of updating those texts with the new information she has written for the 2017 revision of The Magnesium Miracle which is be released in August of this year [2017].

Dr. Dean also uses her blogs to warn people about the mis-use of drugs to treat a magnesium deficiency. For example, articles that tout the latest and greatest anti-inflammatory:  “Novel Compound (that) Shows Promise in Diabetic Nephropathy” by treating inflammation. In her Magnesium Miracle book, she talks about inflammation in chronic disease and that since drugs cause inflammation – you can never treat inflammation with drugs.

With all the excitement of finding this new chemical, researchers are downplaying the side effects. There is something called the Hawthorne Effect where the novelty of having research conducted and the increased attention from such could lead to temporary improvement. The preliminary phase of drug testing was on 75 people and only went for 12 weeks. The reality is that diabetes is a chronic disease and treatment with this new drug could go on for decades.

Notice the way researchers tout this new drug: “This is the first compound we’ve had that interferes with the inflammatory process in the kidney. We now have a ‘big gun,’ which is very focused, does not have a lot of side effects, and is both safe and efficacious in a long-lasting and sustained way.” That type of talk keeps the funding going but it’s no consolation to the people who will develop side effects. The average drug has 79 side effects, so why would this one be any different?

Here is what one young kidney patient said in March. “Before I found ReMag, I was spilling 2500 of protein in my urine. 6 months ago, I was down to 495. I got my results in the mail today and it was 100 !!!!!!! YAY!!!”

Dr. Dean also recommends a specific multi mineral product, which can help heal the tissue damage created by diabetes.  At our clinic, we have a multi-mineral according to your blood type.

For diabetes itself, as our friend, Dr. Roby Mitchell says “You’ll never medicate your way out of diseases you behaved yourself into.” Medicine repeatedly says they have given up on treating diabetes with lifestyle so they opt for drugs and surgery. But the fact is, they never knew how to implement diet, exercise and other lifestyle changes because all they know is drugs.

Drop by the clinic today and pick up your next bottle of Remag!

A New Discovery: A Superior Calcium

Importance of Calcium Supplementation
It’s been well substantiated that calcium is an essential nutrient. After protein, fat and carbohydrates, calcium is the body’s most abundant nutrient. Calcium carries the highest RDA of any other nutrient for a good reason. Calcium is required to form bones and teeth and is also required for blood clotting, transmission of signals in nerve cells, and muscle contraction. Decades of research have linked calcium’s association with lowering high blood pressure and balancing cholesterol levels. Calcium is crucial, but what’s the best source of calcium? Is one source of calcium better than another? Is there really a difference? Naturally, the most ideal source of balanced calcium, as well as other minerals and trace minerals, is from the foods we eat. But our daily Calcium needs often cannot be met by food alone – especially considering today’s busy lifestyles and the depleted soil our in which many of our modern foods are grown. It can be difficult to get a balanced source of any essential nutrient.

A Brief History of Calcium Supplementation
In the early years of supplementation, all calcium was pretty much the same: a ground up inorganic substance (typically oyster shell) packed into hard tablets that early nutritionists hoped the body could absorb. Problem was, the body absorbed very little of this substance-much of it passed through the body untouched and unused. Thus the search for the perfect calcium began. Other sources and processing techniques have been explored: sulphate, lactate, phosphate, citrate; chelated and “micro,” but not all sources of calcium are ideal for all blood types. And what about absorption? With all the new technology, have we seen much improvement? In fact, studies reveal that the body absorbs less than 10% of the most popular calcium tablets containing calcium lactate, calcium phosphate, or calcium carbonate. Through the years, the challenge with all of these approaches remained the same: Either the calcium sources were unfriendly to some blood types, or the inorganic source of the calcium remained the same, and regardless of processing the body still had to deal with absorbing an inorganic substance and attempting to convert it to a useful substance in the cells. This processing of nutrients requires energy from the cells – energy that could be better utilized in other important cellular tasks. What’s more, even though those single-nutrient hard calcium tablets remain popular at the drug store, it’s become standard knowledge that calcium must be taken daily with the appropriate complex of supporting nutrients, such as magnesium.

Better Questions, Better Answers
Up until now, the calcium question had been: “How can we make this substance better tolerated and absorbed by the body?” Dr. Peter D’Adamo asked a better question: “Can we find another source of natural calcium not only friendly to all blood types, but also one that the body can utilize readily with greater efficiency?” Better questions yield better answers, and Dr. D’Adamo found that natural calcium source: Maerl, a small red seaweed found only in the isolated areas off the coast of Southwest Ireland. Of all sources of calcium, Maerl has one of the lowest levels of undesirable contaminants – and one of the highest levels of absorption. Using Maerl calcium as a base, Dr. D’Adamo has crafted Phytocal, four different mineral formulas using unique cofactors and micro-mineral ratios specific to each blood type. Maerl-based sea calcium is composed of a wide variety of essential nutrients including calcium, magnesium, boron and zinc. Maerl is the only natural source of calcium with a broad enough buffering range to insure a phenomenal rate of bioavailability and utilization. In fact, in studies, Phytocal Maerl-based sea calcium achieved nearly double the buffering capacity of all other sources of calcium.

Maximum Buffering: Maximum Absorption
What is “buffering capacity?” We all have differing levels of acid/alkaline content in our bodies and digestive processes. These levels affect the absorption of minerals and vitamins. A supplement that is readily absorbed by one person may have trouble entering the system of another. Phytocal’s unique sea-calcium is buffered by nature, which helps the calcium maintain a consistently high level of absorption from person to person, despite the differences in the acid/alkaline levels.

Blood Type O
‘Type O should continually supplement their diet with calcium, since the Type O Diet does not include dairy products, which can be the most concentrated source of this mineral. With the Type O tendency to develop inflammatory joint problems and arthritis, the need for consistent calcium supplementation becomes clear’, writes Dr. D’Adamo in his book on menopause: ‘You may have heard that a high-protein diet can lead to excess calcium loss, which can be a concern for any midlife woman. However, this is not a danger for Blood Type O, since you have naturally high levels of intestinal alkaline phosphatase, an enzyme made by the intestine to split dietary fat and help assimilate calcium. Furthermore, the high-protein Type O Diet actually causes an increase in intestinal alkaline phosphatase.’

Dr. D’Adamo’s Phytocal O features balanced levels of the micro and macro minerals magnesium, iron, copper and zinc; manganese to help insure proper joint and ligament function, and micro-trace amounts of iodine to enhance thyroid function. Phytocal O also features nettle leaf (Urtica dioica), an important aid to proper intestinal assimilation.

Blood Type A
Dr. D’Adamo: ‘Low levels of intestinal alkaline phosphatase and low hydrochloric acid make it difficult for you to digest meat and can make you vulnerable to osteoporosis.’ Thus, additional calcium from middle age onward is advisable for Type A’s. Dr. D’Adamo’s Phytocal A features higher levels of the important antioxidant selenium, the gastric activating cofactors betaine hydrochloride, rennet and gentian root, plus the mineral-rich herb horsetail. Phytocal A also features significant levels of the important calcium absorption enhancer ipriflavone, and a small dose of vitamin A to enhance the activity of the calcium absorbing enzyme intestinal alkaline phosphatase.

Blood Type B
Dr. D’Adamo: ‘Like Type O, you have relatively high levels of intestinal alkaline phosphatase to aid protein digestion and calcium assimilation.’ Phytocal B features the blood type B-appropriate higher levels of magnesium, an important nutrient for nerve and muscle function; chromium to help balance carbohydrate function and proper doses of iron and copper –two important blood-building nutrients. Phytocal B also features higher levels of vitamin D and vitamin K – important calcium absorption cofactors.

Blood Type AB
Dr. D’Adamo writes; ‘Low levels of intestinal alkaline phosphatase affect your bone health. Type AB has the highest incidence of osteoporosis of all the blood types.’ Phytocal AB features blood type AB-appropriate higher levels of the important co-minerals magnesium, manganese and molybdenum; the stomach-acidifying cofactors betaine hydrochloride and rennet. Phytocal AB also features yellow dock as a gentle source of iron.

For those who, for some reason, cannot take the blood type specific Phytocal products, Dr. D’Adamo created a pure maerl calcium supplement, Clearcal.

How Much Calcium Do You Need?
The recommended level of calcium for adults age 19 through 50 years is 1000 milligrams per day. An intake of 1200 milligrams of calcium per day is recommended for those age 51 years and older. In other countries, calcium recommendations are lower, as low as 600 milligrams daily for adults.Factors which increase the risk of osteoporosis include small frame size, female gender, aging, heredity, cigarette smoking, excessive alcohol, steroid use, early menopause, prolonged immobilization, and inadequate vitamin D.

Blood Type Diet & Allergies

Allergy means “altered working.” Watery eyes and a runny nose are great to wash away germs when your body is fighting a virus. But when there’s no actual threat to the body and it falsely sets off these countermeasures, the normally helpful symptoms serve no purpose and become disruptive.

Immune cells called Immunoglobulin E (IgE for short) are created by the body in response to specific allergens. Once created, the IgE cells can last for months, immediately releasing histamine and causing symptoms whenever an offending substance is eaten or inhaled. Antihistamines suppress allergy symptoms because histamine is the chemical responsible for them.

Environmental allergies can be caused by pollen, animal dander, smoke or chemicals, such as air fresheners or pollution. Pollen is the egg-shaped male reproductive cell of flowering plants. It is typically smaller than the width of a human hair and carried by the wind from one plant to another. Each species’ pollen is slightly different, so it’s possible to be allergic to the pollen from one specific plant but not another or to be allergic to many of them at once.

Food allergies can cause hives, digestive problems, eczema and respiratory reactions. Food sensitivities or intolerances don’t create IgE cells, but can still cause digestive or mood problems and can increase the body’s allergic response to other substances. True food allergies usually cause symptoms within two hours, though some can happen in less than two minutes. This is why an EpiPen is carried by many with severe food allergies – in case accidental exposure to an allergen causes the throat to close rapidly.

Allergies can lead to complications like sinusitis, asthma, or ear infections. Sinusitis can occur when excess mucus in the sinus cavity is not properly drained and harmful bacteria or fungi grow out of control. Ear infections can occur when the Eustachian tube is not properly drained and pathogens take root. Both of these conditions are worsened when allergies increase mucus in the nose.

Extrinsic asthma, also called atopic asthma, is directly related to allergens and IgE reactions. Intrinsic asthma is caused by cold air, infections, inhaled irritants, exercise or emotional distress. Atopic asthma is more common in children, but most asthma sufferers have a combination of both types.

The body’s response to allergens can be mediated by reducing overall stress on the body. This is how the Blood Type Diet can help. Red blood cells have chemicals called antigens on the outer surface, which vary by blood type. Many foods contain natural chemicals called lectins, many of which interact with blood type antigens. Often times the body can handle the effects of dietary lectins or environmental allergens, but trying to deal with both simultaneously can cause symptoms.

Blood type also affects how efficiently we can digest carbohydrates or red meat. “Leaky gut” is more likely to develop when eating foods we have trouble digesting, like those that contain harmful lectins for our specific blood type. This is a type of gastrointestinal (GI) damage where there are tiny holes in the walls of the digestive system, which allows larger food molecules to be absorbed. More lectins and allergens get into the bloodstream where they don’t belong, which can lead to problems. A healthy GI system will break down foods into smaller particles before they’re absorbed, reducing the chance of unwanted reactions. Lectins can bind with IgE molecules and make them release histamine. A diet high in harmful lectins can also increase overall inflammation.

The way blood type is directly affected by allergies is different for each type though. For Type O individuals, dietary lectins react more with IgE molecules, leading to more aggressive allergies and overall inflammation. Type A’s produce more mucus on average and more of a substance known as selectin, which leads to inflammation as well. People with Type AB blood have lower overall immunity, but some of the best resistance to respiratory based allergies. Finally, Type B’s have increased susceptibility to lung inflammation, like asthma, and viral infections. Understanding these distinctions is key to maintaining your health in the allergy-heavy season of spring!
