Yes, we would eat better. And yes, we plan to eat better.
For years I allowed myself to get into the trap of - 'Here's 40 boxes of Hamburger Helper reduced to 20 cents a box. I must purchase them all, and stock them in my cabinets'. Times that by just about every good clearance deal I came across - and I had a massive stockpile of processed crap. (Don't be ashamed to call it what it is) - we would all like to do better at a lot of things (I hope) - but we tend to fall into these little traps.
Since Jan 1 (2013) - we have been eating down the stockpile. And we plan to take it to the bare-nubs (ketchup & mustard being the only things left in the fridge).... that means eating all the 'crap' that I stockpiled all these years. I am already sick of 'crap', I wish we had no more 'crap' to eat. But there is still 'crap' to get thru. (Yea, I could dispose of said 'crap' - but I made our 'crap' bed, now we must lay in it).....
When everything is gone... well, it will be a good day.
I think as I have aged I am getting over the 'massive stockpiling' mentality. Yes, I need to have great deals, just like everyone. (Probably more-so because of my obsessive tendencies) - but, unfortunately you can only stockpile so many 'real' foods. (As 'real food' tends to go bad so much quicker than boxes of Hamburger Helper)
And as for the convenience thing? Well, I know Hamburger Helper helps you help your Hamburger in no time at all... but I have found with the right equipment (crock pot, steamer, griller, etc) - (which one can purchase at any thrift store or garage sale) - you can make a decent meal as quickly with these items as you can opening your Hamburger Helper packaging.
Is it more expensive to eat healthy? I don't believe it. Sure, organics are costly. Honestly, I don't do organics. If I die from pesticide residues, then so be it. But I might as well stop breathing too - cos' I can't filter the air that enters my lungs. I'll just take my chances- (and keep growing my own vegetables). In my neck of the woods - a bag of apples is far cheaper than a bag of Doritos. (And trust me, once your body adjusts to it's new healthy food - you won't be quite as hungry after eating an apple - they will go a long way)
So in answer to your question - yes, I would eat healthier, and yes - I can eat healthier (on my current budget) - and yes, I plan on eating healthier (on my current budget). There are a LOT of good, inexpensive, healthy foods out there - you just have to recognize them. Brown rice & beans & legumes being at the top of the list.
