N.O. children aren't expected to observe Lent until the age of 14???

For real?

Many of the school catering plans  are not Lent-friendly. I think that I've seen meat served on Fridays during Lent in the NO school. Since the age of 14 for obligation age is NO, most catering plans undermine our children's religious freedom. Plus, many say that Lent is harmful for children. The age of obligation for Trads is 7, so we need to crush the "harmful Lent myth".
Lenten eating can be as nutritious than the "healthy", glutton-eating. Like, bread can substitute meat. Also, the intake of fish is important. Fish is rich in omega-3 fatty acids, so it should be eaten at school age. Also, children are eating less fruit and vegs nowadays. What do you think? Can you give me ideas on casting out the liberal myth?
(NOTE: not to be confused with full abstinence)

I guess I am confused about what the liberal myth part is? Are you referring to the opinion that Lenten eating is harmful for children? Your thread title is throwing me for a loop, because families I know that are very concerned with healthy eating are, for the most part, trads.

I agree that Lenten eating can be nutritious. I think it a bit dangerous to suggest that bread be the subsititute for meat though, if you are making the argument for nutrition. A vegetarian main dish would be a better suggestion.

 If you are looking for ideas to present to the school, maybe you could research some options first. Obviously the to meet certain standards the school would have to swap nutrition for nutrition. Find out what your area has access to in regard to fish or wholesome grain or legume type products.  Fish intake is great for you, but many schools will not buy it do to cost or region availability.  Obviously increasing vegetable-eating is a wise choice.

Even public schools in my area have the option of swapping the main course for a PBJ. Does your school not offer this? Or the option to bring lunch from home? Just curious.

The first step, in my opinion, would be to show how little nutrition the current meal-plans actually provide. Meat products (hotdogs), french fries, bleached-enriched rolls, bagged lettuce- all horrible for you for various reasons, but for some reason school boards insist on feeding kids this crap. French fries considered the vegetable! ha!  You could then present the school with the resources you have come across for healthy meat alternatives, and better sources for local fruits and veggies.

I've never understood the popularity of white bread.

It is cheap and stores longer.

It was not something people chose freely.

Of course, communion hosts are a different matter.  

They're "exceptional" - set apart - consecrated.  One might expect that someone
like me who has utter disregard for white bread can have such a reversal of
regards for the matter of the Blessed Sacrament.  Maybe someone else can
explain this because I can't.  And I should be able to.  Any help out there?  

You do not receive Communion for material sustenance and you are used to it being white.

Whole wheat bread is definitely healthier eating than white bread, but I have
always had suspicions when hosts at Mass are not white, but tan or spotted,
like grainy from the wheat germ in whole wheat.  The wheat germ is the most
nutritious part of the grain but it makes communion hosts look, well, somehow
wrong.  Can anyone explain this for me?  

You are just not used to it.

If I saw something unfamiliar with the matter of a sacrament, I would be uncomfortable with it until I learned about it.

You may be unfamiliar with leavened bread being used as that is never used in the Latin Church, however, it is used in the Eastern.
