Ignoring private schools, it really depends on locale. Most schools are run by a combination of local and state guidelines. So each state has its own minimum standards, which are then implemented on a district level.

However, in some districts, the budget isn't equal between all schools.

So you can have varying quality within the same school system, and even more between different systems.

The good thing about school meals is that they aren't usually super expensive, don't require packing only foods that won't spoil or be gross by lunch time, and there's usually some kind of budget for free reduced cost lunches (sometimes breakfast too) for those in need. It makes sense that most students will choke down even the bad options instead.

Some schools do damn well though. The bulk is usually going to be supplied by one of the industrial food distributors, but most of that is similar to or the same as what you'd get in terms of ingredient quality as chain restaurants.

So the staff of the cafeteria can make a huge difference in quality right there. Knowing how to turn fairly meh ingredients into something tasty is a great thing.

When schools supplement with fresh produce, it can be damn good food. Local farmers out in rural areas often contribute. Some high schools have agriculture programs where they grow stuff that gets used in their own school, and may be distributed to others. Our closest high school supplements their own cafeteria, plus the elementary schools, and part of the jr high schools (some of those have their own gardens, so they tend to handle their own). My kid was very happy with the high school's food, unlike the food at their jr high in another state that they hated.

I ate at the high school a couple of times. Waaaaaay better than when I was a student there, and the agriculture program was starting up back then. Mind you, the lady that ran the cafeteria was doing a great job with what she had. The supplies were just crap back then. All canned shit for veggies if it wasn't grown local, mandated recipes on a schedule set by the county, so you could only do so much to improve things. She ran a damn good kitchen though, so even when the food was bad, we knew the cooks were doing their best.

And that's pretty much the problem with school food. It just isn't a nationwide priority.

It absolutely depends on where the funding comes from. I know someone who works student nutrition for a school district that doesn't receive state funds, it's all county school tax funded. They chose to contract out to a company that provides the food. Usually this is a recipe for disaster, but they actually provide high quality food. All fruit or vegetables are fresh, not frozen or canned. All food is prepared fresh daily, no microwaves. Their food is so good, every employee that she knows, eats the food too. This is in stark contrast to prison food level quality found in many districts.

The same companies who supply food to American public schools also supply food to American prisons. Make of that what you will.

If you're curious about the history, public school lunches were federally funded and made free under FDR during WWII to combat malnourishment, especially for high schoolers who were getting drafted after turning 18.

It was so successful that the US continued the policy even after the war ended, and hence cafeterias became the default since they include a large kitchen that's capable of producing high quality food at large quantities.

That is until Reagen, among a crap ton of other things, nuked lots of the socialist policies which included free school lunches.

Schools continued to produce lunch, but you had to pay.

40+ years of insane decline later, and public schools are so under funded that they can't even afford to produce lunch in their cafeterias anymore. American consumerism shoved its way in, so now everything is prepackaged garbage made as cheaply as possible from the same conglomerates that make unhealthy trash that's often banned by other countries due to health risks.

The final killing blow was when Michelle Obama failed to tackle this core issue in her student health campaign, and they forced public schools to ban essentially flavor as a concept (anything "high" in salt, spice, oil/fats, calories, etc).

Everything was switched over to "healthy" options which literally just meant low fat/zero calorie slop or sugar slop.

If you want a real kicker, the chocolate milk they served at my HS had 28g of sugar per serving lol. But don't worry because the vending machines now only have baked potato chips and diet soda.

Charter and private schools aren't really affected by this since they have alternative funding sources.

Locales differ but in my experience:

1. no one is required to eat the cafeteria food
2. the cafeteria food has a cost
3. the cafeteria food quality was low when I was young but not terrible, and is much improved now
4. many kids absolutely do bring their own lunch. My kids look at the monthly menu and decide if they want to bring something from home or eat what’s being offered at the cafeteria

To be honest I find your question confusing. It seems to start with the question of whether everyone has the option to buy items or eats at the cafeteria, but then jumps suddenly into “is the food that bad.” I don’t honestly understand quite what it is you want to know.

When the government allowed corporations into the schools with soda and snack machines in exchange for a kickback in the 80s, any hope of a bureaucrat looking out for the kids' health was dead. Once they could use the excuse that most kids weren't making use of a subsidized nutritious lunch(very loosely using the phrase) because they were bringing their own or eating their lunch from the machines, they didn't even need to try any longer.

(Ironically, a post from a corporation installing the vending machines points but it makes the necessary points)

Schools are run by cities, counties, with oversight and regulations divided between every level, all the way to Federal.

There are minimum standards set for nutrition but many kinds of schools are exempt from providing meals or meeting the minimum.

Some schools go above and beyond, providing nutritious breakfasts, lunches, and snacks that the students can take home. Others, on the other hand, see it as a hassle and do the bare minimum.

Many US schools are misfunded, with many layers of unneeded bureaucracy and testing added, pulling resources away from the classroom and cafeteria.

Former american student here. Yes, absolute garbage. Same as prison food.

It varies a lot by school. My highschool was okay, but I still preferred to pack a lunch from home. My kids' elementary school found is awful and if I don't pack lunches for them they just won't eat.

In my state, cafeteria food is free. There are no longer any pay choices so you either take the free food or bring your own

I won’t claim it’s good food, but it looks much better than the garbage I had when I was in school

Yes its horrible.

But the alternative is to starve children...

In NYC free school lunch was a thing in public schools. I don't remember it being that bad. But I was used to Chinese food for the first 8 years of my life so that was a bit of a stuggle...

In Philly schools it wasn't free... and I obviously did not wanna bring food cuz... oh jeez imagine the racism... there are barely any East Asian looking kids in the elementary school... so I sort of just starved...

I thought it was free since that's what I was used to in NYC... and my parents never asked either since we just assume it was the same

So you can imagine the awkwardness...

Back then my parents didn't have the wealth they had today...

And like its not like I'd feel like asking for money either... its shitty and I would've hated it anyways...

Then later became free I think? Can't remember.

Just googled it, apparantly they made it free in the fall of 2014... just a few months after we moved to Philly...

Anyways, Philly school lunch is horrible. I remember it worse than NYC.

so why do American kids rely on cafeteria food instead of bringing their own?

POVERTY

Lol are you from a middle class or rich family?

In my country, there’s no US style cafeteria

When I was in China (for 1st and 2nd grade), we just went home for lunch...

then we walked back to school again...

5 flights of stairs to my apartment... ugh...

Imagine making a 6/7 year old walk those stairs down and up 2 times a day... no wonder why I never got fat in China lmfao...

There is school lunch but you pay like ¥5-¥10 rmb or something like that.

Sometimes my grandma wasn't home to cook stuff so my parents just give me money so I eat lunch at school. They just cooked rice and stuff like just normal Chinese food.

Its kinda quiet at noon... like most kids went home for that hour or so for lunch... it'd be weird to walk around the empty school.

It's technically a "private" school but its only because we weren't allowed in the public school for legal reasons (issues with Hukou), its worse than public school.

Also like I never seen anyone bring a lunch in the US schools I've been to. Maybe because everyone here is from working class families, I think those comments here thats say they do bring lunches are from white suburbs or something.

It depends on where the school is, and even then it is still an industrialized large scale service.

American dad here. Yes, it’s trash.

Moved to Japan for my son and the difference is night and day. People here are shocked and disgusted when I tell them what I ate for school lunches as a kid.

at my current school the food is the best I've seen, the main stuff even includes gyros which I've never seen before in public school food

the district also has free lunch for all kids no matter what income status!! (NYS)

US schools do not always have cafeterias and many students don't use them. They cost money and bringing a lunch is cheaper. I know there are movies/tv with kids bringing their lunch and trading items as well as buying things from the cafeteria. Sometimes its setup were the parents paid for them to get a meal every day with a kind of pass or another style where its kinda billed to an account. So im guessing you have seen media that made you think kids always use a cafeteria but man you someone avoided the ones showing kids bringing lunch. Anyway some kids use when there is one and some don't.

My teenaged kid's school has free lunch for all students. I often offer to pack a lunch for my kid, but they decline. If they don't want me to, I won't, and I like that my kid taking a lunch defuses the stigma of "poor" kids taking a free lunch.

Broadly, there is a lot of food insecurity, especially in big cities, so cafeteria food may be the only meal some kids get. In the US, many school districts also send home backpacks stuffed with nonperishable food for the holiday breaks, and summer lunch programs are offered. The decision to close school for inclement weather also involves deciding if some kids wont get to eat that day. So fortunate is my family that we dont have to worry about that.

It's really bad. My kids pack a lunch because they said school food hurt their stomachs. I thought they were being dramatic/picky at first. Then I tried it myself. It's so much worse than when I was in school.

In my day the food was never good but it was usually reasonably edible and that's all anyone expected from it. It's probably worse now.

I still remember "Turkey 2-Hydroxy Tetrazzini".

Most kids still pay for the shitty standard cafeteria lunch tray...

Sometimes in later in like highschool they're given more options. But it's pretty much comes down to capitalism.

The vast amount of parents won't pack a lunch and will never even see the quality of food.

What's fucked up is healthy food is actually insanely cheap at that scale and dependable need. We'd spend just as much feeding kids a healthy high protein/fiber low sugar/fat meal as we do giving them ultra processed garbage.

There just would be profit margins for contracting companies if we did that

Likeost things in America, no system is designed to be the best or most efficient at anything other than making money. Anything that doesn't make money, the wealthy are constantly trying to privatize.

That's the whole "late stage capitalism" thing people always say.

Yes. My schools eventually offered a 'snack bar' which was decent food for more money, if you didn't want the garbage the cafeteria line served. We also, in high school, got pizza delivered and sold by a nearby restaurant every day. I ate a lot of pizza during that time.

The hs cafeteria fries with seasoning was actually really good though. Though it's not very hard to cook a batch of fries...

I recall it being quite bad.

Late 90’s, early 2k’s, it was far more disgusting that just “trash”. It hasn’t changed any since then, either. The food is all microwaved, deep fried or baked; all from frozen. And you might be inclined to think baked stuff wouldn’t be so bad. But the only thing that came out of an oven was the pizza - and I’m pretty sure they’d have fried that too, if they could.

The closest any of that came to decent food is when the delivery truck passed by the grocery store.

One time, a friend had grabbed strawberry milk, and ended up gagging on a gelatinous rope that some how came out his nose. (You know the pasta trick? In the mouth? Out the nose?)

It came out to jiggle on his tray like pink snotty jello from hell.

The only reason people ate that crap is largely because they didn’t have a choice.
