No idea.
I'm always one of those who does the most washing loads on those threads too.
I buy bananas 3x a week.
(Fruit and veg in general at least twice a week)
We get through a toilet roll every day.
A loaf of bread every day.
I try to buy British, buy local, buy seasonal in the main, I don't buy palm oil, I try to keep the additives we eat to a minimum but I do buy curry pastes regularly. And spices,
We buy our eggs, jam and honey locally,
I bake rather than buy packaged snacks.
We aim for ten a day on the fruit and veg front and in enough variety to ensure 30 different fruit and veg a week.
We don't eat meat, but I add tofu or use a chicken substitute in some of the curries I make, a "mince" one for lasagne or spag bol, and I do veggie burgers once in a while. (Not every month, I find it an expensive meal as we like the pricier ones and everyone but me has two burgers in a bap with salad and sauces. But the kids like it.)
We eat nuts which can be expensive, and seeds, I buy wholewheat everything. We shop in one of those refill shops for what we can, and almost all my cleaning products are the eco versions. I recently made myself finish up all the cleaning products I don't like, and it was quite miserable.
My lot would scoff marmite on toast and an apple whilst waiting for some left over chilli and rice to heat up as an after school snack because it's about three hours since lunch and about three hours until dinner!
