In 1998, the USDA started spraying synthetic folic acid on wheat, rice etc and (some) other grains and began adding it to milk products. These are ‘fortified’ products and are usually labeled ‘Fortified’.
Unfortunately many people don’t tolerate synthetic acid very well, and its presence can lead to low level problems including elevated inflammation in the body. This, of course, is not healthy.
‘Organic’ grains/milk are not supposed to contain synthetic folic acid (sometimes they lie). To investigate your susceptibility to synthetic folic acid, try replacing grains and milk and dietary supplements with products which don’t contain it. Select products with natural folic acid instead. See if there’s any improvement. :)
I’ve heard from others that synthetic vitamin Bs can be a problem.
I’ve been having trouble with them lately myself. Sigh....
It just isn’t getting any better.
Mark!
