Yes, you can take food through UK airport security in 2026, but the process is governed by the "obstructive" nature of certain items. Solid foods like sandwiches, fruit, and snacks are permitted in your hand luggage. However, UK security guidance explicitly suggests packing powders and large food items in your checked (hold) luggage whenever possible. This is because dense food can obstruct the clear images of X-ray machines, frequently triggering a time-consuming manual bag search. Additionally, any "liquid-adjacent" foods—such as honey, marmalade, yogurt, or soft cheeses—are subject to the standard liquid restrictions. While many UK airports are currently upgrading to scanners that allow up to two liters of liquids, "liquid" foods in larger containers may still be rejected if the specific airport has not yet fully transitioned to the new 2026 technology.
