Water or liquids are not allowed, otherwise ok
You can bring most foods through. I take my own sandwiches and home made things all the time. I have learned by doing this that you are almost guaranteed to get searched. Organic foods have the same xray appearance as some banned things. So they'll have search any bag that has food in it. People with toddlers for whom they carry food through security (this is me too!) can vouch. And you can check the TSA website.
I am almost positive that TSA will not let you thru security with any food that is not in its original sealed packaging.
Might want to check the TSA website, but I think you can.
