There is no potassium deficiencies in my house. Bananas are a staple! :D
I know though that both potassium and magnesium are two often overlooked deficiencies that cause a huge array of common health complaints as well as some odd ones! It just goes back to the basics of eating your fruits and veggies and nuts! And in modern times, it needs to be stressed that the less processed and/or cooked they are, the better. More nutrients are found in raw form.
Yai yah. We note that Jared Diamond's Guns, Germs, and Steel informs us that bananas were "domesticated" in the vicinity of New Guinea, linking to banana streak virus (Caulimoviridae). The cauliflower mosaic virus promoter is used in hepatitis B studies, and not far away, Baruch S. Blumberg (NASA Astrobiology) discovered the Australian antigen of hepatitis B. We will post the citation for low potassium in children (December) when it is retrieved from the archives.
On the supposition that increased number of dog-bites post-Fukushima have a relationship to earthquakes, and perhaps "metal mouth," we note that there was an increase of rabid dogs in Washington, D.C. during the years 1908-9. From a veterinarian report, we will later show that 1909 was the highest amount of rabid dogs for Washinton, D.C. up until 1922. The largest earthquake ever recorded for Europe happened on 28 Dec 1908 at Messina, Sicily. We have been watching the earthquake reports and if not mistaken, there is an increase in the number of quakes for Sicily at this time. One can check the chron for themselves, here:
Here is the supporting evidence for low potassium in December:
'When we come to mammals, we find that according to Franke (Arch. Kinderheilk.  ) children show a sharp rise in the growth curve from Ap to Jun, a drop during the summer months, a second rise in Sept and Nov, and there is a dip in the curve again in Dec and Jan.'

The caulimovirus promoter in banana-streak virus would link this potassium, yet we must return to the nightshade thread for the ebola virus link.
