Oat milk is safe during pregnancy. It's naturally higher in fiber and carbohydrates than other plant milks. Most commercial brands are fortified with calcium, vitamin D, and B12. If you have celiac disease, choose certified gluten-free oat milk.
A "Generally Safe" rating means this food doesn’t carry a pregnancy-specific safety concern beyond ordinary food-handling practices — the same basic hygiene and storage habits that apply to anyone. These ratings are based on general guidance from the FDA, ACOG, CDC, and USDA rather than a claim that every possible preparation of the food is automatically fine; how something is prepared, stored, and served still matters. If a "generally safe" food has any handling caveats (like a preparation method or freshness window), they’re noted separately in the sections below rather than changing the overall rating.
