Wow! Still so many posts utterly unaware of the effects likely headed our way AND the reality for far too many families already in the uk.
I can absorb it JUST, fortunately, but I already only eat one meal a day so hardly extravagant anyway. Never get takeaways or eat out (housebound) I'm already veggie and frugal generally speaking.
I'm extremely worried about the many single parent households and others with already VERY tight belts who will have to tighten them further.
I can all too well remember skipping meals myself so dd would eat.
In addition posts like this:
We would just have to eat in season and british food
We will not die because we cant get french cheese German sausage and any other food from eu
Yes it will be different but we will adapt
Show a HUGE and frankly terrifying lack of knowledge on here alone despite the major supermarkets, grocery organisations etc plus posters on Sm with industry knowledge posting frequently regarding;
We DO NOT even come CLOSE to producing enough food within the uk to feed all the people in the uk - at any price!
Food and drink you perceive to be "made in the uk" is mostly dependent on various eu related factors like:
Machinery
Materials necessary to farming like fertiliser, insecticides etc
Farming subsidies - which the uk govt has merely vaguely said they will 'cover'
Experienced farm labourers
Processed food and drink is heavily reliant on ingredients, machinery, packaging etc from the eu
Have you checked the price of meat and similarly 'luxury' products from British farms? Do you know how little even people on benefits receive and how that won't cover such prices? That's of course not including those who slip through the net or are awaiting first benefits payments.
Staggering blind, ill informed, selfish attitudes.
We ALREADY have people in the uk dying literally of starvation on a regular basis. So actually YES more will probably die 
Funnily enough the person who moans the most about food prices increasing & probably increasing more after Christmas is the friend who voted for Brexit.
She gets a very hard stare & then she changes the subject
I'm finding it harder and harder to not snap at such people in real life, and I'm fully expecting those not moaning yet to be the most annoyingly vocal post 1/1/21
oh and do not forget medicines and beauty products
Medicines is what I'm most worried about. I'm on a medication that's dangerous to stop, can only be prescribed one month at a time and not one dr or pharmacist I've spoken to yet has been able to say there's been ANY plans put in place for such issues.
Plenty of Californian and South African wine on the market.
I don't see many labels with "Spain" or "Italy" on them. More commonly "Morocco", "Costa Rica" etc
Question - how do you think products from countries outside the eu actually get to us?
Hint: it's not often directly imported
Plus
Yes. The EU have a fairly extensive trade deal with Morocco which takes account of various sectors including food, and also a deal with a bunch of central American countries inc Costa Rica. These deals will no longer apply to us when we are out of the transition period.
It's really not just about the trade deals we have within the eu.
Veg no problem. Loads of winter veg in this country. there's really not. Even if we stop exporting we still don't make enough food to feed our population
If we had a decent intelligent govt we MIGHT have been able to improve matters slightly by supporting farmers to increase production a little but really that takes several years up to a decade to make any meaningful difference.
Interesting at least one person mentioned wwii/rationing - you might want to learn a bit more of the reality there too because that led to health consequences inc death for certain people, plus black marketing and farm thefts. It was NOT a golden age of everyone working together and acting fairly as is often portrayed in fiction.
Obesity rates fall and grocery bills don’t increase, it’s a win-win.
Not how population obesity issues work it's more complex than that, the cheaper foods are the more "fattening" ones
