On the good side, snacks can help prevent over-eating at meals. And taking time out for a little snack can be a nice respite from a hectic day. Snacks can also help balance a mood if blood sugar is out of whack, preventing meltdowns in kids and even in adults (manifests as unjustified impatience and frustration.)
So as I see it, there's no harm in a snack every so often.
But it seems to me that today's wee generation (and I can say this because I created two members of it) thinks of snacks as an entirely different thing. To them, snacks are a daily guarantee. It's as if snacks are their own food group. I don't remember this being the case when I was little, so I asked my mom:
I don't remember snacks being very much a part of our lives at all. Maybe because I was taught not to eat between meals? I know we had pretzels around, and bananas and other fruit, mostly apples. But I don't remember you guys ever eating in the car on the way to do errands or soccer practice or anything like that. Do you?
Nope, I don't. But I don't know too many parents nowadays who dare take their kids in the car without snacks. I certainly don't. Having an emergency stash on hand is smart, but when the stash becomes the expectation rather than the exception, it's a slippery slope: kid doesn't eat his breakfast - he knows he'll get a snack if he's hungry... kid eats that mid-morning snack and then isn't hungry for lunch... so kid doesn't eat lunch but is hungry in a few hours so he gets a mid-afternoon snack... and so on and so on.
This wouldn't be such a problem if the latest definition of "snack" wasn't so warped. (And actually, this situation would likely be much less prevalent if the latest definition of "snack" wasn't so warped!) When my four year old asks for a snack, I offer fruit, veggies and hummus, nuts, or - dread! - her leftovers from the previous meal. And I'm very emphatically told: "Those aren't snacks!" To be considered a snack by Maggie standards, it must come from a box or bag with a questionably long shelf-life.
The odd thing is, my kids actually really like fruit, veggies and hummus, nuts... so what gives?
Can I blame school? The ubiquitous 'snack time' that seems to be synonymous with piles of bright orange fish?
Can I blame the expansive center aisle of the grocery store? The shelves packs with overly sweet, overly salty, overly-processed "foods" that didn't exist 30 years ago?
Can I blame other parents? After all, an apple is booooooo-ring when it's sitting on a bench next to a bag of cinnamon teddies.
It might make me feel better to place the blame elsewhere, but the reality is whether some or all of these things are true, none is an excuse. Healthy eating habits are ours to teach our kids... or not. And frankly, I think many of us have gotten a little lazy.
I'm never going to be able to control what my kids are given at someone else's house, or at snack time at school, or if they're sitting next to a bag of Doritos at the playground. But I can control what I give to them. I can control what I have in my cupboards, my car and my purse. And I can control how much of their real meals they eat (or at least what that means for any sort of snack entitlement later.) And if I'm doing right by them when I have that control, I can give them a better shot at making their own good choices when I'm not around.
