Comment by Dr. Grimes in a Video June 2011

• 10% of the cells in our body are human = 10 trillion
• 90% of the cells in our body are microbial = 90 trillion
• 25,000 human genes
• 1,300,000 genes just in our intestine
  There are far more genes in our body which might be influenced by vitamin D than we have been aware of.

  Wonder if bacteria in the human gut concentrate stuff, say vitamin D, the way bacteria concentrated iron for the vikings
• Fungus found in intestines June 2012
  200 species, 100 of which had never been described before
  Recall that just bacteria outnumber human cells by 10X - and this does not count virus and fungus

Intestinal fungus from previous reference

Apparently there has been no investigation of bacteria genes and vitamin D bioavailability

Even though non-human genes make up 99% of the genes in the human body

Another way to state it. The human body probably shares less than 1% of the genes with a banana

Observation: Inuits have greatly reduced uptake of vitamin D from foods - some of their local food has toxic level of vitamin D

Wonder if that reduced intake is due to changes in human genes or bacterial genes

They Outnumber Your Cells Ten to One but Researchers Show they Play Crucial Role in Your Health Mercola April 2011

Highlights

• There are 100 trillion cells in your body, but only one in 10 is human. The rest are bacteria, fungi, viruses and other microorganisms, i.e. your microflora.
• Your microflora influence your genetic expression, your immune system, your weight and your risk of numerous chronic and acute diseases, from diabetes to cancer.
• It is becoming increasingly clear that destroying your gut flora with antibiotics and poor diet is a primary factor in rising disease rates.
• Gut Bacteria Divides People Into Three Types (similar to 4 blood types)
