Every membrane of every cell in our body (phosfolipids), how we digest in our stomach (Hidrochloric acid), every hormone & brain (cholesterol made of fats)etc. We need a good acidic pH to metabolize fat in the best fuel our body needs to get KETONES, and brake proteins to have aminoacids. Without fat and proteins there is no structure to sustain. Those are block molecules we need to survive. So education on physiology is better than a superficial chat about what is in reality pH, Hidric potencial and the chemistry involved in biological terms of survival and healthy life. Just one example: how many people have digestive problems because they use antiacids? their ph is not enough acidic in the stomach to use protein and fat and nurture themselves: they are obese, they have insuline resistance or diabetes but their bodies are starving and they are sick. So is a little more deep than 'eat alkaline diet" Ignorance is dangerous.
