In an era where we are really just starting to understand how what we eat impacts on both our mental and physical health, I think it wouldn't do any harm for people who are feeding their kids a lot of sandwiches to at least pause and think.
I think the average uk ultra processed food consumption is 57%, with up to 90% apparently not uncommon.
Assuming the bread is bought from a shop rather than home made, if you feed your child:
Toast, margarine and jam for breakfast, that's likely to be 100% ultra processed. If you go for wheatabix and milk, the cereal is still UPF. Many children will be eating higher-sugar and lower-fibre cereal than wheatabix too.
A wholemeal bread, spread and ham sandwich with a fruit yoghurt for lunch- again 100% ultra processed. In my house, while fruit would be eaten, things like carrot/cucumber batons probably wouldn't be.
So a child could easily get to dinnertime having eaten very little non-processed food, and only 1 portion of fruit.
While meals don't need necessarily need to be hot (agree that there's nothing wrong with a salad, though i wouldn't usually choose to eat one 🤣), I am interested at how little reflection goes on when it comes to whether we are really feeding our kids well.
Some studies have implied that high ultra processed diets are as bad as smoking, but I guess because a lot of us grew up eating shop bought bread, ham, crisps, a chocolate biscuit snack etc etc for our lunch, we just feed it to our kids without pausing and considering what it could be doing to them (and to us too!!!)
We're also supposed to be eating 5 portions of fruit/veg a day, and ideally 30 different plants (regardless of portion size- herbs and spices also count) per week. The trouble with lots of sandwiches is as well as usually being highly processed, it makes this pretty hard to achieve.
