Here we go again. Regulators forced synthetic folic acid into bread and now they are finagling it into corn products. California decided corn products need folic acid and now companies like Siete are reformulating products nationwide rather than making separate versions. That means Americans everywhere get the California treatment and regulators and Big Food have essentially nannied us again. In their effort to protect a small subset of Americans (pregnant women) they've subjected another subset of Americans (people with MTHFR variants) to potential problems. What's so bad about synthetic folic acid? There's concerns about FA's contribution to the growth of cancerous lesions. There's concerns about FA masking a legitimate B12 deficiency. There's concerns about excessive amounts of unmetabolized FA floating around in our blood because our body can't process it all. Proponents say : There's no proof that synthetic FA is harmful. I say: The onus to prove safety belongs on those pushing the supplement. Why is it the consumer’s responsibility to prove it's not safe? If adults want supplements, they can buy supplements. Lawmakers shouldn't be sneaking them into everyone's bread and now tortillas. Just look at history to understand what's at risk here. Every time government tells us what we should and shouldn't eat, they eventually end up saying, "Oops, we were wrong. Don't do that anymore." Somebody please tell me the Latin phrase for "Government, please shut up."
