I recently saw a billboard with "better ate than never", the phrase was new to me so I looked it up and found.
In addition to wasting precious resources, nearly all of the food waste ends up in landfills where it decomposes and releases methane, a form of climate pollution that is up to 86 times more potent than carbon dioxide. In fact, food is the single largest contributor to U.S. landfills today. All this while one in eight Americans don’t have a steady supply of food to their tables.
Source Reducing Food Waste
Every year, 40 percent of food in the US is thrown away without getting eaten, contributing to the 1.3 billion tons of perfectly edible food that are lost or wasted worldwide annually, according to the United Nations' Food and Agriculture Organization. Considering that almost a billion people go hungry every day in a world that produces more than enough food to feed everyone here, it's worth being aware of from an early age.
The implication is that if wealthy (relatively), consumers stopped wasting food, it would impact hunger for the less fortunate.
I have no doubt food ending up in landfills is problematic.
I also agree that a food bank is a better place for excess food to go.
A leap of logic, implies that if consumers only buy what they are going to actually eat, there will be little or no consumer wastage.
Edit, include to explicit claim
Cutting food waste by a quarter would mean enough for everyone, says UN source
If all wealthy consumers stopped buying food that they ended up throwing out, would it help the billion hungry people in the world?
