Olives are safe and nutritious during pregnancy. They contain heart-healthy monounsaturated fats, iron, vitamin E, and antioxidants. Both green and black olives are safe. The main consideration is sodium from the brining process.
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.
