Are people that lazy that they can't go to a healthfood store and pick up an inexpensive bottle of vitamin D and supplement?! There should be NO reason why our vitamin D levels are falling in this day and age.
According to data from Statistics Canada, vitamin D levels for Canadians is declining significantly. The mean average vitamin D blood levels for Canadians between the ages of 6 and 79 years of age plunged to just 63.5 nmol/L in 2011 (a 6.2% drop from 67.7 nmol/L in 2009).
The reduction in vitamin D levels was consistently found across all age groups and for both sexes. Children age 6-11 years represented the largest decline at 10.2%. The lowest levels overall were found in young adults age 20-39. Males had vitamin D levels generally below females for all age groups with the exception of boys aged 6 to 11.
Only 68% had vitamin D blood levels sufficient for healthy bones (at a mere 50 nmol/L), with only 10% reaching optimal levels of over 100 nmol/L.
This reduction is very concerning since many research studies continue to show that people with lower vitamin D levels are at a much higher risk of developing numerous serious diseases.
The study also found that only 34% of Canadians took a vitamin D supplement and 85% of these users reached a cut-off level of 50 nmol/L compared with only 59% of people who did not take supplements.
Since vitamin D can be made naturally in your skin when exposed to UVB (ultraviolet B rays) in summer sunshine, this helped 75% of Canadians tested in the summer months to reach the 50 nmol/L cut-off versus only 60% of those tested in the winter
A large group of prominent vitamin D doctors, researchers and scientists recommend that people achieve optimal vitamin D blood serum levels of between 100-150 nmol/L for best overall health and disease prevention.
Studies of East Africans living naturally, with few clothes and high sun exposure, revealed that evolutionary human vitamin D levels are close to 115 nmol/L(4). This is a vitamin D level 80% higher than the new Canadian average of 64 nmol/L.
A study published in 2010 reported that if all Canadians reached a vitamin D blood serum level of 105 nmol/L we could expect an annual reduction in healthcare costs of $14.4B!
So who's not pulling their own weight in helping to reduce our healthcare costs (A.K.A. taxes)?!
