I don't spend 2k, but a US data point-

   1lb of rice: 0.89$
   1lb of rolled oats: 0.69$
   1lb Cherry tomatoes: $4
   (Quality) chicken breast: $8

In other words they sound similar. However, there's a shop downtown that sells all the same things for 30% more.

I suspect people with crazy food bills are:

   1) in exceptionally expensive locations like SF or Switzerland
   2) buy more packaged food
   3) eat out more than you
   4) maybe are taller than you

In regards to the last, I swear my (short) friends eat half what my (tall) family does.

Food in other countries is so much better and cheaper. We stayed in Mexico for a few months (not saying I want to live there) and food was all organic and dollars. A bag of about 15 avocados cost $1-$2 dollars. In the US that will buy you maybe one avocado.

Dozen eggs = $5-$8 Bag of apples = $5

We have some food allergies such as sensitive to gluten (wife is celiac).

Two things broken in US (that are pain points for us now) - food cost and healthcare. I pay about $800 month for healthcare that is essentially a safety net for an accident ($5K deductible). I am not sure why universal healthcare is not viewed the same as public schools. Many people dont have children but still pay taxes for schools and education. I would probably pay less than $800/month in extra taxes for healthcare.

A dozen of eggs for $5-8 is shockingly expensive. That’s like £3 at the absolute limit in the UK. And they would be some primo organic shit.

american here, $2K per month sounds like a pretty wild food budget for a family of three (one of whom is presumably a child). I spend $300-400 a month to feed myself, and I could cut that down a lot if I didn't primarily shop at whole foods. if you aren't focused on saving money, there are a lot of opportunities to spend extra money on stuff that isn't healthier (eg, prime NY strip vs flank steak, fancy aged cheese, high end butter/oils). the nicest version of something in a grocery store can be 2-3x as expensive and nutritionally equivalent.
