If St. John can eat locusts, I can eat pork.

Actually locusts were permitted.  They are mentioned in Leviticus 11:

[21] But whatsoever walketh upon four feet, but hath the legs behind longer, wherewith it hoppeth upon the earth, [22] That you shall eat, as the bruchus in its kind, the attacus, and ophiomachus, and the locust, every one according to their kind. 

You missed my point.
All animals are fair game (pun intended).
This is an asinine discussion for Catholics.

I was just throwing that in as Bible trivia.  You are right that it is not relevant to the discussion.  

This is asinine, but I think it is important to come down hard on it due to its association with heresy.  St. John Chrysostom, for example, was dealing with Judaizers in his community and he did a series of homilies against it, using strong, emotional language.  This is serious.

What people forget is that we are to have the simple Faith of a child.  
Do children worry about what they eat?  No, they are to eat what is put before them, just as the New Testament tells us to do.
Keep the Faith simple.

I am the mother of a family.  The duties of my state of life include things like shopping for food, planning and making meals, and trying to keep my children healthy.  I do not have the option of not thinking about what we eat.  If I were to do that it would be irresponsible, probably to the point of being sinful.

I suspect that only a minority of adults have duties that allow them to merely eat what is before them without giving it any thought.  If they do, it does not mean that their faith is better, simpler, or more childlike than those of us who are responsible for feeding people.

Unless you are feeding your family 100% organic food you are still putting dung before your family.
My point is that we are to do the best we can for ourselves and our family.  God will sort out the rest.

That is the main problem. This crisis of many people not being able to afford to eat clean meat is a manufactured crisis. Hopefully this will all soon change.

Grass-fed beef and lamb are especially healthy kinds of meat (although there is no command binding on Catholics stopping us from eating anything else).  They are significantly more expensive than most other meats, in part because they take more resources to produce.  Most people could benefit from eating a smaller quantity of meat and use the savings to buy better quality.

There are serious problems with the standard American diet, including many food production and availability issues.   However much it is need of reform, I do not expect to see change.  There are very powerful forces that benefit from keeping things this way.

You sense that things are very wrong (which I agree with) and perhaps that is why you are expressing your concerns about food in religious terms.  But you are coming up with objectively false statements, saying things that Catholics may not believe.

Jєωιѕн ritual laws concerning clean and unclean food were given to foster obedience and identity as God's people.  There is nothing in Scripture to suggest that God gave these laws as a health measure.  While some people have tried to make a case that there are health benefits to the kosher laws, this has never been proven and is a minority view.

Your ideas about healthy eating are relatively reasonable but you need to stop confusing them with religious precepts.

Support your local farmer/rancher.
.
Join with other families and buy a grass fed cow and have it butchered.  Where i live it costs about $3 per lb of meat you get back.  This way the ground is the same price as the filet mignon.  Price does vary depending upon the type of cow purchased (Waygu, Angus, jersey, etc).
.
And you can get the organs (for you or your dog), bones (for you or your dog), and excess fat (for tallow Or soap making), free with the processing.
.
So there is no real excuse for the average family not to have good beef.

While I agree with your recommendation, I suspect that the "average family" is not going to have the skills to do this.  I have the impression that a large proportion of young people now do not know how to cook from scratch and would be overwhelmed by the unfamiliar cuts and meat by-products.

I am not sure what I can do about this at the level of society, but it indicates what sort of skills I need to convey to my daughters.

We are not eating dung in properly managed food. Aged manure put in gardens has nothing to do with eating dung. The vegetables get the nutrients from the aged manure. We are not eating the manure.

Do you eat out or buy ready to eat food?  Do you know how often people preparing your food don't wash their hands after going to the bathroom?
.
Etc
.
What I am hearing from you is that you eat ONLY food GROWN in the earth, never go out to eat, and never eat pre-made food?
Anything else, and you are eating dung of one form or another.
