I have so many random thoughts to add. I don't think home cooked meals are without flaw. The vast majority of our meals were homemade. I grew up eating, and loving, every vegetable but they were all dripping in butter. They tasted lovely, but did not help my weight. I was also told that I had to clear my plate, even when I was full - because "there are starving children in Africa". This still has an impact on my life today (I don't tend to get the "belly is filling up" signal until it's too late and I almost feel sick). I don't make my kids clean their plates. When they tell me they're done, they're done.
Unfortunately, we were sold a lie. We were told that a "vesta curry" was the answer to the busy woman's prayers. A little extra help in the kitchen, and people found them handy. And, in truth the ready meals and products sold in the 70s/80s (not sure exactly when vesta arrived) were probably not too bad. But today's UPFs are highly addictive substances. They have been specifically engineered to make them taste as good and be as addictive as possible.
Also, we are a lot less active than we were (as a whole), and portion sizes are colossal!
In our local bakery, the cakes are so big that I struggle to eat even half. I think people don't realise the amount of calories that they're actually eating unless they're actively tracking them. It's eye opening.
I think there's almost too much availability of food also these days. There are takeaways, cafés, fast food restaurants on every corner and now you don't even have to leave your house, you can uber eats until your heart desires.
I can cook well. I've always been interested in food. I grew up in a food-oriented family, and watching jamie Oliver and devouring any cook books and magazines I could get my hands on. I was lucky to learn to bake with my Granny. Home Economics was not what it used to be, and not every person grew up like I did. I have a friend who has asked me to go to her house to show her how to cook because she was never shown how. I make things like curries (but add spinach and chickpeas), lasagne, gnocchi bakes with butternut squash, roasts, stirfries, Chinese takeaway dishes (such as chow mein, sweet and sour, chicken and cashew nuts, etc), fakeaway McDonald's sausage and egg bagels... cakes, biscuits, pies, confectionery.
Interestingly, my now-adult daughter hated that I cooked every night and would tell me that it was horrible to have to eat these home cooked meals every night and she was deprived, and why couldn't she have the 'good food' like her friends etc, etc. She had a boyfriend for a few months who would come round for dinner (his own mum didn't cook and he ended up eating takeaways every night), and he kept telling her how lucky she was that I cooked. You can't win!
