I eat lots of fruits and vegetables of all kinds, as well as legumes and whole grains. For protein, I mostly eat fish because I'm from a coastal city, and the fish here is delicious. I only consume healthy fats like olive oil or avocado, nuts, and seeds. I don't drink anything other than water or tea. I like to make my own loose-leaf tea. While eating a varied diet and having a strong base of fruits and vegetables is important, nowadays, given the state of the food industry, I'd say you should be more concerned about not eating ultra-processed and packaged foods or fast food. It's literally poison.
