It means so much, but it seems very technical.

It means all things to all people.

It can mean, has a household got enough money to feed itself or our parents enough? very often going without meals in order to try and get something on the table for their kids.

And it can mean, is there enough food to go around in the world? So it's a very loose term.

And people like me have argued it's almost so loose it can mean all things to all people.

But the looseness actually can be quite valuable.

To answer your question, Britain has a real problem with food security.

Well, Finland just lives with a constant hybrid warfare problem.
