Yes, you can take food through TSA airport security. Solid food items such as crackers, nuts, cakes, cooked meat, sandwiches, dried fruits, and vegetables are generally permitted in both carry-on and checked bags. However, liquid or gel-like foods such as yogurt, jams, syrup, nut butters, and sauces must follow the TSA's 3-1-1 liquids rule, meaning they must be in containers of 3.4 ounces or less and fit into one clear quart-sized bag. There are some exceptions, such as baby food, formula, breast milk, and toddler beverages, which are allowed in reasonable quantities beyond the 3.4-ounce limit but should be declared for separate screening. Frozen foods are allowed if they are completely frozen during screening. Certain fresh fruits and vegetables might face restrictions when traveling to places like Hawaii or U.S. territories due to agricultural rules. Also, TSA officers have the final say and can reject any items they find suspicious. In summary, bringing solid foods is usually straightforward, but liquid or spreadable foods have to comply with liquid rules, and some special categories have exemptions.
