What did California’s folic acid rule change?

California’s folic-acid rule for tortillas and other foods

In January, California became the first U.S. state to require food manufacturers to add folic acid to certain products such as tortillas. The change is aimed at preventing neural tube defects, which are serious birth defects that occur early in pregnancy.

Why it matters

The policy is explicitly tied to racial and ethnic health risk. The measure was introduced because Hispanic communities have a high rate of neural tube defects. By adding folic acid to commonly eaten staple foods, the state is trying to make prevention more consistent—rather than relying only on individual supplementation.

What it signals for public health

The step reflects a broader public-health approach: when a nutrient deficiency or risk is linked to predictable patterns of diet and population risk, regulators may use food fortification as a population-level intervention.

Key takeaway

California is using mandatory fortification of widely consumed foods to reduce neural tube defects, with a focus on addressing higher rates affecting Hispanic residents.
