Okay. So your main issues are that you're not using the correct properties for what you're trying to target.

let name = document.getElementById('food').value;

This line is failing because there is no value property for the getElementByID method. It's meant to be innerHTML if you want to retrieve the text value.

document.write(uff);

This here inside your else statement is also incorrect.

'uff' is a variable that has not been defined.
document.write will clear the entire screen and print out whatever arguments you've placed inside there.

Here you can find a pen of more or less how it should look.
