Our obsession with clean

Why it’s making us less healthy

Doug Anderson

Jan 25, 2026

In the 70s and 80s I was a microbiologist and chief lab technologist in the local hospital

Throughout eons of evolution, from the lowly earthworm to the present, we’ve had a close association with dirt – which is home to millions of bacteria, moulds, etc. (Earthworms are essential for turning that dirt into the soil that sustains the plants which feed us.) Up until a few centuries ago, we didn’t know any of this but those microorganisms were and are essential to our existence. As with all animals cleanliness was not something that concerned us.

We didn’t have soap, we didn’t take showers … and we survived and multiplied.

(Archaeological research indicates that some early soaps appeared about 3,000 years ago but there is little evidence that it was in common use until relatively recently.)

We learned that there … More

Why I take a lot of vitamins

Back around 1960 my aunt developed breast cancer and had a radical mastectomy (breast, lymph nodes and all – that’s what they did back then). She was told that if she had no secondaries for 10 years she could consider herself cured.

Nine year and several months later a secondary appeared, and that began a long series of further secondaries – each followed by surgery, radiation or chemotherapy regimes which made her life miserable. Like a lot of people in similar situations, she was ready to try anything. At the time there was a little book entitled “Folk Medicine: A Vermont Doctor’s Guide to Good Health” by Dr. D.C. Jarvis, which had been on the New York Times Bestseller list for the previous 2 years. Its prescription was apple cider vinegar and honey. My aunt read it and … More

My vitamins

ByDoug Anderson Health

I take a lot of vitamins because I don’t believe that humans consume anywhere near the quantities that they would have had during their evolution on the savannas of Africa.

In most of the listings below I have included the recommended daily requirement from one source or another

These supplement are of course in addition to what I get from my food.

Vitamin A – WebMD Recommended – Men: 900 mcg/day, Women: 700 mcg/day
Vitamin A aids in the development and maintenance of night vision and aids in maintaining the health of the skin and membranes.
I take 10,000 IU every other day (Halibut Liver Oil capsule -10,000 vtt A/ 1,000 vitD)
Both Vitamin A and D are fat soluble so they are stored in fat and in the liver.
Skim, 1% and 2% milk is fortified with 1,200 international units of vitamin A per litre, as required … More

Survival of the Fittest: A Primer on Evolutionary Medicine

Doug Anderson

Jun 16, 2025

Evolutionary medicine is a legitimate but rather obscure branch of medicine. It studies humans and their ailments from the perspective of where we came from originally.

Homo sapiens evolved on the savannas of Africa about 300,000 years ago. Just to put the timeline in perspective, Christ lived 2,000 years ago so our species came into existence 150 times that ago. And moreover our species was preceded by several less developed Homo species over a period of several million years.

The first humans probably did not wear any clothes and lived in the open unless they could find a convenient cave for shelter. We were hunter gatherers. The food we ate was mostly eaten raw (in spite of the fact that earlier Homo … More

As a dentist, what is one thing you think all people should know about dental hygiene that they might not know already?

I’m not a dentist but I am a bacteriologist and the main thing that few medical professionals recognize is that our microbiome (the bacteria in our bodies) evolved right along side with us. Most of our bacteria are either beneficial or innocuous – that includes our oral bacteria. A small number are harmful and these include the Strep mutans which cause cavities. However among the beneficial functions of the good bacteria is that they inhibit the bad. This happens throughout the body – in the gut (well established), on the skin (less understood) and the mouth and nasal cavities (understood by microbiologists but not by the dental profession).

Humans are the result of hundreds of thousands of years of evolution alongside our … More
