Your problem isn't the arrays, your problem is this code:

node.innerHTML += newFood;

This code is very, very, very slow. It will traverse all exising DOM nodes, create strings from them, join those strings into one long string, append a new string, parse the result to a new tree of DOM nodes.

I suggest to use a framework like jQuery which has methods to append HTML fragments to existing DOM nodes:

var parent = $('#foods');
...
for (var i = 0; i < foodList.length; i++) {
    parent.append( "
                
                0
