Great that you got rid of anorexia.
I disagree with you saying that being concerned about your food makes you mentally unhealthy. The Standard American Diet kills people in huge numbers.
Also moral is attached to our foods. Being conscious about your food is more than healthy.

Our body is our existence and should be cared for just as much as we should care for our mind and soul. None can strive without the two others.

I understand that you having anorexia in your past makes your alerted when it comes to the subject of food, body image, health. But in fact nothing is black or white and these correlations, just like we humans, are much more complex than just ‘fatphobia is bad’.
