I grew up on eating a balanced diet (at least that's what I think) until I moved from home for college and jobs. Like many of us, I occasionally cook at home due to ease of restaurants or food delivery services like Freshly etc. here in the Bay Area. Now that I have started getting shoulder and back pain, mostly due to poor sitting habits, I'm thinking to change my habits and learn to live and eat better. I found some good exercises online but didn’t find any curated list of food that is good for the body.
What I'm more interested in is how to have a balanced diet. For example, in one of the YouTube videos on shoulder pain, the doctor linked it with a possible dysfunction of the liver/gallbladder and recommends eating beetroot tops and other cruciferous leaves. I was wondering if there's this ultimate guide which talks about good eating habits and links it with the improvements of the body organs. Does anyone know about this kind of guide or like an app?
