Health is on the way


Why do we get sleepy after eating?

The Facts, Myths and Magic


By Dr. Don Davis
Epicture1very year during the holidays, most of us temporarily suspend our health goals and start
eating.  It begins in November with a big bump on Thanksgiving
and cruises through December with a crescendo on Christmas and New Year’s.  Inevitably your weight will rise and you will be making familiar resolutions to exercise more and eat less.  In fact, most Americans report that they gain an average of 5 to 10 lbs. over the holidays.  Unfortunately, they won’t lose all that weight afterward, leading to an expanding mid-section year after year.

The Gut, Inflammation and Depression

America is finally realizing that depression is a serious concern. Of course, the pharmaceutical companies have known for years that there’s money to be made, but now society is on full alert. It’s taken a few miss-steps with celebrities, but the message is clear; those suffering from depression aren’t just having the “blues”, they are suffering, and in a big way. What can we do to help these people? Well, this is one of those times where the best approach is to get back to finding the underlying cause.

Vitamin B12 Problems?

Is It From Diet Deficiency or Poor Absorption?

by Doc Don Davis

There are many health problems that aB12re linked to Vitamin B12 levels but most doctors assume that it’s a matter of deficiency. In reality, at least in North America, it is much more likely an issue with absorption. It’s thought that about 30% of people over 60 are affected by low B12 levels (aka hypo-cobalaminemia).


B12 is vital for proper brain and nerve health and so it’s linked to many brain and energy maladies like memory loss, anemia, cardiovascular disease and numbness, tingling, depression and loss of cognition that can be the beginnings of dementia.


Years ago it was believed that B12 deficiency was due to dietary intake because of the predictable deficiencies that can occur with vegetarian/vegan diets and the problems in developing countries. While it is true that this presents a problem, we find that even people with adequate meat in the diet are prone to this condition.

Contrary to popular belief, not only strict vegetarians (vegans) are at high risk of vitamin B-12 deficiency.

Am J Clin Nutr February 2009 vol. 89 no. 2 693S-696S

Since dietary intake is usually adequate, that leaves poor absorption as the major reason for B12 deficiency. This is by far the most common reason for low B12 and the subsequent declining brain dysfunction and anemia.

Stomach acid and Vit B12?

graphAbsorption of B12 occurs in the intestines but must have a healthy stomach that produces stomach acid and intrinsic factor tomake this happen. Unfortunately, stomach acid declines with age which affects the level of intrinsic factor and then the B12 levels start to plummet. This can be helped and actually reversed with supplemental hydrochloric acid (HCL).


Intrinsic factor can also be lowered when you have a condition called Pernicious Anemia that can cause fatigue, lethargy and weakness. This is an auto-immune condition where the body attacks the cells that make intrinsic factor. In this case, treatment must include the immune system as well as the low levels of hydrochloric acid.

How about inflammation?

There are other reasons for decreased B12 absorption, like bacterial overgrowth, intestinal inflammation and gluten sensitivity. Inflammation can make it difficult for micronutrients like B12 to pass through an inflamed and damaged gut lining into the bloodstream.

The Adolescent Gut – Brain

Adolescentby Doc Don Davis


Nobody wants to see a child suffer.  It doesn’t matter if he/she is a toddler or a young  adult. The point is: it just shouldn’t happen.  I know personally, the only thing I can’t watch in any movie is when a child is uncomfortable, stressed, or is left alone.  Maybe It’s just me, because of some issue in my past, but I suspect that almost all of you reading this feel the same way.  The utter dependence on those adults in control is a special circumstance in the world, one that isn’t replicated in any other domain.


Suffering doesn’t have to come from the hand of a care giver. I’m speaking here to the internal physical issues that affect children in a way that increases both physical and mental stress.

BAD BREATH and 4 Gut diseases that cause it


Hi there, it’s Dr. Davis again and today I’d like to talk about halitosis or bad breath. Well, specifically about the causes of breath problems that may not have occurred to you. Of course bad breath won’t kill you but it surly could kill a relationship, and for that matter, kill a career if your work has any social component. Bad breath doesn’t only affect the sufferer but those that are close by. These, of course, are the same people that are wondering if they should say something or just bear with it and not stand too close. But more importantly, bad breath equals bad health. In this case your breath doubles as a barometer for the health status of several body systems. The good news is that modern testing and treatment for halitosis has advanced way beyond flossing, and it works.

Infertility and the Gut Bacteria


Male Infertility problems

By Dr. Don Davis


Infertility is an increasing problem, and the male’s side of the equation is estimated to be 40-50% of that problem.

Unfortunately, in most of these cases the cause remains unknown, so a study recently that sheds light on this is welcome news. Interestingly, the gut and the bacteria that live there seem to be the culprit.  In this study, it was found that the bacterial composition of the semen can affect infertility. And where did the bacteria come from? The gut!  Not only that, the testing actually found the same bacteria and the same proportions.

The researchers took 96 semen samples and found that the type of bacteria residing there was related to semen health factors like semen volume, sperm concentration, motility, antisperm antibody (IgA) and leukocytes (white blood cells).

What is Irritable Bowel Syndrome?

By Doc Don Davis            .................. I’m sure you know the feeling, even though you may not know the name. Irritable bowel syndrome or Spastic Colon is one of the most common intestinal disorders. Most doctors and patients find it hard to clearly define just what Irritable Bowel Syndrome is. It used to be a diagnosis of exclusion where the doctor would finally label your symptoms as IBS when they couldn’t think of anything else to call it,But IBS research has advanced so much in the last 5 years that it has cleared the path to a much fuller understanding of the cause and effects of IBS. This syndrome – or collection of symptoms, may start with (photo) indigestion, bloating, gas and abnormal bowel frequency and then progress to (photo) abdominal pain, cramping, heartburn, diarrhea alternating with constipation and nausea. In addition, many patients have what…

The Second Brain- in your Gut

By Doc Don Davis            .................. Today I’d like to talk about a second brain that we all have that resides in our intestines.  You would think one brain would be enough, but we actually have two brains; one at the top of the spinal cord and one large, powerful “brain” in the gut, called the enteric nervous system.  Anyone that has given a speech and experienced the predictable performance-related stomach distress knows that your gut is listening closely to your brain.  But what can the brain learn from the stomach?  As it turns out, plenty. You see, the brain and the gut, including the esophagus, stomach, small and large intestine, and colon are intimately connected by the huge vagus nerve in a two-way street. Scientists were recently shocked to learn that about 90 percent of the vagus neurons carry information from the gut to the…
