I prefer to listen to my books on audible by Amazon, but if you like reading, yay on you!
As for the educational (nutrition/diet) books, I do not endorse the diets laid out in every single one of these books. I think it’s important to be informed of everyone’s opinions and make the best decision for you. LISTEN TO YOUR GUT. USE COMMON SENSE. The foods today are not what they were 50 years ago.
