It doesn't make sense to count food waste in kilograms, you should count it in USD. With USD in pocket you can always simply farm more food. Or just import food from abroad poor countries, helping their people.
One big waste is buying expensive food like in restaurants or organic. You can eat healthily for less than 2 USD / day if you prepare meal yourself from mass produced ingredients.
Buying and eating one 20$ restaurant meal is much worse than wasting 10kg of potatoes. Ask the people who really have problems with lack of food if wasting 20$ (restaurant) is better than wasting 2$ (potatoes).
