How did our grandparents get by on the meat and three veg every night, followed by lashings of whipped cream and apple crumble? Luncheon sausage sammies for lunch, biscuits and tea with sugar, scones and butter, baking done with full fat milk, butter, and cream - I seem to remember my Nana living on full butter shortbread, coffee with cream, and cheese scones.
My granddad's favourite dinner was stuffed curried sausages and they had those once a week. Both were whippet thin.
So how much does the modern food marketing industry play into our insecurities - and our social media feeds which constantly tell us what we should look like and what we should eat?
How much of it's just selling a fad, versus what we actually need? 5:2, Keto, Atkins, Mediterranean, Paleo, Raw - I bet you know at least one person on at least one of these diets.
Eating has become so complicated these days.
I used to drink protein shakes and take lots of vitamin supplements, believing it would balance out any zinc or iron I was lacking elsewhere. But when I stopped doing all that and just started eating whole real food, including full fat milk, I found I'd never had more energy and never felt healthier.
No I'm not (obviously) a high performance athlete or running a marathon anytime soon… but I can tell you I feel better for it. Even if it does mean I'm not a size 6 anymore.
