Most of us eat a bit too much and its widely known that portion sizes are generally too big.
It’s something all of us should be willing to consider and re-visit every couple of years, rather than assuming that the plateful we have is right or necessary.
Especially with dishes like cottage pie, people might cook an extra large dishful and do some batch cooking. Perhaps it’s not a meal that is generally cooked as a 2 portion meal, so when you see the ingredients or the finished version for just 2, it looks small. That’s because the one people cook when they buy their own ingredients tends to be bigger.
And I say again, that I think in most families where 1 person dies the bulk of the cooking,it’s usually the woman. The man can be quite passive in his portions and just eat what he’s given/what is available. That 4 portion cottage pie using 500g if mince can be put out for a family of 3 and everyone has a good plateful and then a decent second helping that they don’t need…..just because it’s there. And suddenly that is the normal portion and portion size for the family. And women in particular don’t like to offer the man a small portion or underfed, so often have the idea the man must need a huge portion. Well actually, most of us could eat a bigger portion than we need. If you passively just eat what’s it in front of you, like lots do, it’s easy to overeat.
I agree with a PP upthread, that in the past, recipe books allowed about 110g meat per head….that was for people doing largely active manual jobs. Of course there were lots of other parts of the meal too. We don’t need heaps and heaps of protein. But over time, plates have grown and people eat more. It’s just something we should all consider rather than assuming what we eat now is perfect ir the only right option.
