When we were kids we didn't understand or care about "nutrition" or diets or any of that stuff. Food was just food. You ate it at breakfast, lunch and dinner. Mum or someone else usually prepared it, and then you went off to play with your friends.
And then as we got older and learned a bit more about "nutrition" we started having issues and concerns with food.
Our relationship with food was probably best when we were kids.
Then, all of a sudden there were 'good' foods, 'bad' foods, specific ways and times to eat them.
Food stopped being food and became components and parts. There were good fats, bad fats, hi glycemic and low glycemic carbs, soluble and insoluble fibre, complete and incomplete proteins, organic vs regular, vegetarianism and on and on...
The more you stress about it the worse your relationship with food gets.
I was recently chatting to a very good friend of mine who said she'd written "it's just food for fuck sake". It was a reminding realisation for me. A Zen moment. Food is just that, food.
I hope one day all of this fussing and stressing over food just goes away for good and we can all get back to living our lives without food being a constant worry.
