In 2026, most solid food items are fully TSA-approved for your carry-on bag, but the "liquids, gels, and aerosols" rule remains the primary hurdle. You can freely bring snacks like nuts, beef jerky, granola bars, crackers, and solid fruits (apples or oranges). However, any snack that is "spreadable" or "creamy"—such as hummus, peanut butter, yogurt, or salsa—is classified as a liquid and must be in a container of 3.4 ounces (100ml) or less to pass through security. Interestingly, a sandwich with peanut butter is usually fine, but a jar of peanut butter is not. A peer-to-peer "pro-tip" for 2026: frozen liquid items (like a juice box) are permitted as long as they are frozen solid when they go through the X-ray; if they are slushy or melting, they will be confiscated. Always keep your snacks easily accessible, as TSA officers may ask you to remove food from your bag to ensure a clearer X-ray image of your electronics and other gear.
