Which foods have the most vitamin C?

Do you go more for fresh vegetables and fruits or do you buy frozen ones too?

Because the top sources of vitamin C are mainly citrus fruits (oranges, lemons, grapefruits), kiwis, and berries like black currants. There's also plenty of vitamin in bell peppers, especially red and yellow ones, in tomatoes, and in sauerkraut. And sauerkraut is really helpful in fall and winter because vitamin C holds up pretty well during fermentation. Fresh cabbage works too, you just need to eat it fresh and not boil it for ages.

The main thing to remember is that vitamin C hates heat and long storage. So if you bought oranges or tomatoes, it's better to eat them sooner rather than having them sit in the fridge for a week. I recommend frozen berries - they keep their vitamins better than fresh ones that have been transported and stored for a long time. And don't boil these products in tons of water if you want the vitamins - either eat them raw or stew them briefly.

Vitamin C breaks down quickly when heated and during long storage, so fresh vegetables and fruits are indeed better. But here's what's interesting: frozen berries often contain vitamin C just as well as fresh ones, because they're frozen right after harvesting, without sitting on store shelves for a long time. The main thing a lot of people forget - vitamin C from tomatoes, bell peppers, and fresh herbs (parsley, dill) is absorbed better if you eat them with sour cream or vegetable oil. On their own, the vitamin doesn't stay in your body as well.

It's not quite right to narrow it all down to just citrus and berries 😊 Bell peppers, especially red ones, actually have more vitamin C than oranges, plus there's sauerkraut - vitamin C stays great in it thanks to natural fermentation. Tomatoes, fresh herbs (parsley, dill), even potatoes in their skins - all of these are pretty solid sources, people just tend to forget about them.

Your observation about frozen stuff in the previous answer is spot on, but I'd add this: flash-frozen vegetables are often healthier than fresh ones that have been sitting in the fridge for a while, because they're processed right after harvest 👍

Rose hips are actually the champion when it comes to vitamin C - if you brew them, the content is several times higher than in citrus fruits. I agree that peppers are an excellent source, and frozen berries really do preserve the vitamin well, but with sauerkraut I'd clarify: vitamin C is partially lost during fermentation, though of course more remains than with heat treatment. The simplest approach is just to eat fresh oranges, kiwis, or tomatoes - no cooking needed and you get the full amount of vitamin.

The main thing is not to get stuck on one source - it's better to mix it up! I agree that bell pepper is top-tier, but I'd be more careful with sauerkraut - vitamin C does stay in it, yeah, but the losses during fermentation are still pretty significant. From experience: it's easier to just grate fresh pepper or eat a kiwi with an orange at the same time than to wait for sauerkraut to cover your daily needs. And frozen berries - that's not a myth, just make sure you grab ones without any additives, the ones that aren't loaded with sugar!

actually, vitamin C is found in some pretty unexpected places - for instance, regular parsley and dill have more of it than oranges, people just eat them in smaller quantities. but I'm totally on board with the sauerkraut thing, it's a genuinely good way to preserve vitamin C during processing. and by the way, frozen options are actually a decent choice if you don't have fresh ones - the key is that they freeze them quickly after harvesting, so the losses are minimal

In practice, I've noticed that vitamin C isn't just found in exotic stuff. We have regular black currants growing at our dacha, and they're absolutely packed with vitamin C. A handful of berries from the bush and you've practically hit your daily requirement. Plus there are summer tomatoes when they're ripe and straight from the garden - also a pretty solid source, though people seem to forget about that for some reason.

For stuff that's available year-round, fresh herbs work well (parsley, dill), sauerkraut like people mentioned here already, and plain onion. By the way, if you store onions properly, they lose vitamin C really slowly, so it's a reliable staple during fall and winter. But fruits and berries lose it quickly in storage - better to eat them fresh, obviously.

As for frozen stuff - yeah, I agree it's a solid option. They usually freeze it right after harvesting, so the vitamin C doesn't really have time to break down. Frozen currants or strawberries in winter are a lifesaver if you don't have fresh berries. Just one tip though: thaw them in the fridge, not on the counter - that way the vitamin stays better preserved.

# Rose hips are totally overlooked, which is a shame. It's actually packed with vitamin C - even more than oranges, honestly. You can brew it like tea and the vitamins stay intact just fine, since the dried fruit has already been processed.

I've been doing it this way for a long time: I grab whatever's fresh when it's in season, but I dry some things for winter when I can find them. It keeps great, and when I need to boost my immune system - I brew it up. Plus fermented cabbage, like someone already mentioned - it actually works, vitamin C stays in there with that method of preservation. But heat treatment - yeah, that's enemy number one for ascorbic acid.

The main thing is not to get fixated on one source. If you rotate between citrus, peppers, kiwi, rose hips - you'll get way better results than eating oranges day in and day out. And you don't necessarily have to buy everything fresh - frozen berries actually keep vitamins pretty well if they were frozen properly.
