Welcome to c/news! Please read the Hexbear Code of Conduct and remember... we're all comrades here.
Rules:
-- PLEASE KEEP POST TITLES INFORMATIVE --
-- Overly editorialized titles, particularly if they link to opinion pieces, may get your post removed. --
-- All posts must include a link to their source. Screenshots are fine IF you include the link in the post body. --
-- If you are citing a twitter post as news please include not just the twitter.com in your links but also nitter.net (or another Nitter instance). There is also a Firefox extension that can redirect Twitter links to a Nitter instance: https://addons.mozilla.org/en-US/firefox/addon/libredirect/ or archive them as you would any other reactionary source using e.g. https://archive.today . Twitter screenshots still need to be sourced or they will be removed --
-- Mass tagging comm moderators across multiple posts like a broken markov chain bot will result in a comm ban--
-- Repeated consecutive posting of reactionary sources, fake news, misleading / outdated news, false alarms over ghoul deaths, and/or shitposts will result in a comm ban.--
-- Neglecting to use content warnings or NSFW when dealing with disturbing content will be removed until in compliance. Users who are consecutively reported due to failing to use content warnings or NSFW tags when commenting on or posting disturbing content will result in the user being banned. --
-- Using April 1st as an excuse to post fake headlines, like the resurrection of Kissinger while he is still fortunately dead, will result in the poster being thrown in the gamer gulag and be sentenced to play and beat trashy mobile games like 'Raid: Shadow Legends' in order to be rehabilitated back into general society. --

Important to note that supply != consumption and that you still need to account for wastage, which (at least in the US) is significant. The most wasted categories of food tend to be perishable animal products and a lot of that wastage happens at the household level, so it's difficult to tell how much of that is actually being consumed.
I’m not sure how it is elsewhere but in America, between restaurants, grocers, homes etc. we throw out sooo much food while people starve. It’s disgusting.
Here it's roughly 40% of edible calories! When you count wastage by overconsumption, we waste enough food in this country to feed a whole additional country.
Doesn't the majority of food waste occur before it's bought by the consumer?
Depends on the categories you're looking at and what method of accounting you're using. If you're looking just in terms of raw tonnage, the majority happens at the farm/distributor/processor and the grocery store (the EPA puts it at 60/40 upstream/downstream), but the picture is a little bit muddier if you're tracing protein or calories instead of weight. Grocery stores mainly throw away produce because they build those nice pretty displays to get you into the store but they're horribly inefficient from a distributional perspective. Meats and other short-shelf-life products are often purchased and brought home, then allowed to go past the expiration date in the fridge, so the preconsumer and postconsumer components are closer to parity on those categories compared to produce. A lot of that waste also comes from wholesalers like Costco because no one is buying $90 worth of salmon in a single shopping trip, but in terms of total volume they're smaller than grocery stores.
