Every year now I remind people the earth has shifted on its axis and the sunrays must pass through a thicker atmosphere to reach the earth’s surface and this reduces UV-B fast tanning rays/vitamin D-production in humans.
So at the first sign of a runny nose, sore throat, ear pain/infection, fever, start gargling with salt water (alkalinity counters the acid making strep bacteria in your throat and kills them); instill hydrogen peroxide in your ears; avoid sugary foods that paralyze white blood cells; use sun lamps if you don’t want to take vitamin D pills; and start supplementing your diet with 10,000 IU/day of vitamin D in deep winter and 50,000/day when ill + 500-1000 mg vitamin C every 3-4 hours when ill + 30 mg zinc (not zinc oxide, very insoluble) and better yet zinc acetate lozenges that shorten the duration of a cold (other forms of zinc lozenges don’t work as well). Swanson Vitamins offers zinc acetate lozenges for $4.99. (Swanson Vitamins) Elderberry syrup is helpful too. If you don’t have these items on hand, you will likely be taking a trip to urgent care.
Hey, this is life-and-death stuff for older adults and those who are in ill health. The death rate in the world rises in winter. The number of heart attacks skyrockets in winter. Death due to pneumonia is a wintertime problem. Winter is the season for cancer. Dental caries (cavities) occur more often in winter when tooth enamel is softer due to lack of vitamin D combined with increased sugar intake (sugar feeds streptococcus bacteria that are acid-forming bacteria and the acid causes the cavities). Forget flossing. Washing your mouth with baking soda or salt water at bedtime kills off the strep bacteria.
By the way, researchers in Britain figure out 4000 units/day of supplemental vitamin D3 was needed to achieve optimal blood levels for 88% of subjects (given 70% of the time they remembered to take vitamin D pills); 2000 IU vitamin D/day achieved optimal blood levels (90 nanomole/Liter of blood) for 70% of subjects. Only 1% of subjects achieved optimal blood levels without supplementation (must have been using sunlamps). There was smaller weight gain among the D supplement users.
