i see this a lot. And in theory you’re right, it should be achievable to eat healthily on a budget.
however. What a lot of people forget, and I didn’t realise until I was in that situation, is it’s not just about the food budget.
i had to move into a small apartment with my kids temporarily. Storage and cooking facilities have a massive impact.
no freezer, only an icebox in the fridge. Nowhere to store the affordable frozen veggies. Limited fridge and cupboard space, no where to store the big cheap bags of lentils and rice. Small preparation surface, no dishwasher. Cooker had one shelf. No ability to batch cook in large amounts, even if I had a freezer. If I got the slow cooker out there was no where to prepare the food. I had to do one thing, clean and wash up, rinse and repeat which meant I could never time dishes to be ready.
no transport to the supermarket. Which was useless anyway as nowhere to store a “big shop”. So it was pretty much daily trips to the Tesco extra. That’s not cheap. Add in the fact I worked full time meant we ate more takeaway than I’d have liked, but I could pick something up on the way home, no washing up and no trying to cook.
Apples do cost the same as a chocolate bar. But they go off relatively quickly. You can’t have a choice of fruit and veg lying around because there’s no fridge or counter space and it goes off. So again, it’s off to Tesco everyday for a couple of apples after a day at work. Chocolate is smaller and keeps for ages.
so yes, lentils and frozen veggies are cheap and nutritious. But if your budget is that low it’s likely you don’t have a big spacious kitchen and a chest freezer in your non existent garage.
