That does not break down the type of food waste

For example I rarely have meat-based food waste, however, I have all kinds of Fruit, and veg food waste do to spoilage.

Meat is easy to freeze and preserve, it is hard to freeze a salad ;)

It's mostly down to only buying what you need / use really. Frozen vegetables are another option, they are often easily portionable and are a better choice than "fresh" vegetables (source: I used to work in a vegetable packing plant for a summer vacation job; the vegetables we packaged to be sold in shops the day after came from a big freezer / fridge, oftentimes we had to discard whole pallets because the brocolli had gone moldy. I have no idea how long that stuff had been in there, but given the amount of mold it must've been a while)

I was surprised how much meat people smilingly throw away in NewZealand - when I was asked to "just throw it in the trashcan" around 30dkgs of perfectly delicious and cooked meal I simply refused and walked away.

My muscles were literally blocked to make that movement of my arms, swiping a plate of meal to the bin. Around ~25 other people did not have any problems with it, so I guess the problem is in me.

Not just in New Zealand. It hurts me when I see people not finishing their plate. I will eat myself sick before I will throw away food. Sadly, this has developed into a bit of a weight problem. And then there's restaurants and supermarkets which throw away enormous amounts of unsold food.

We should buy and cook less food, or maybe have a quick way of sharing left-over food with people who are hungry.

Obesity is now a bigger problem worldwide than hunger.

Is that because hunger has been diminished, or because obesity has increased?

I believe both are true.

I thought I read that obesity is growing faster than undernourishment, but I can't find a source on that now.

It looks like the number of obese [1] and undernourished [2] humans are both currently 700-800+ million.

Better to waste than to waist.

(Yes, take less on your plate, save leftovers for future meals, etc.)
