Yes, you can generally bring a wide variety of food in your hand luggage, but it must adhere to the TSA's 3-1-1 rule for liquids and gels. Solid food items such as sandwiches, fruit, nuts, bread, cooked meats, and solid cheeses are almost always permitted without restriction. However, any food that is a liquid, gel, or spread—such as yogurt, peanut butter, jam, hummus, or soup—is limited to containers of 3.4 ounces (100ml) or less and must fit inside your quart-sized clear bag. One important exception in 2026 is for parents: reasonable quantities of baby food, breast milk, and formula are allowed in larger containers, though they must be declared for separate screening. Additionally, if you are bringing fresh produce or meats on an international flight, you must check the agricultural regulations of your destination country, as many nations prohibit these items to prevent the spread of pests. To speed up security, place your food items in an easily accessible section of your bag, as TSA agents may ask you to remove them if they obscure the X-ray image.
