I think there needs to be more 'personalised' medicine and health.
About 1 year ago I was diagnosed with type 2 diabetes. I did a lot of reading and watched a few TED talks.
Then I got a Libre 2 - you can get a free sample, you have a sensor you put on your arm and use your smart phone to take reading of your interstitial blood glucose.
It meant I could track how my body responded to different foods. Or at least how much glucose got in to my blood.
And guess what caused a spike? A banana.
12 months later I eat protein for breakfast and a low carb diet, not no carb. This has actually increased my use of processed food simply because it is easier to measure 20g of carb if it is in the form of croquet potatoes or other potato products.
So some swaps, instead of low fat yoghurt with fruit for breakfast I now may have high fat Greek yoghurt with nuts.
I've lost 10 Kg, my A1C was 36 last week.
