What Exactly are Acid/Alkaline Foods?

I have recently come across an interesting fact, one that never really meant too much to me before.  All foods are either adic or alkaline and they both have a major effect on our constitution.  One unusual fact that I have discovered is that just because a food is considered acid it's not necessarily so.  Wow!  Imagine that, a lemon isn't acid at all, it's actually in the alkaline range of foods; that also applies to the lime.
Apparently the way we eat can have a significant affect on our digestion and you know what that means.  No more bloating, no more indegestion, no more heartburn.  It seems a very simple way to solve many of these problems that plague so many of us on a daily basis.  Yes I've just discovered that by altering a few of the foods we regularly consume we can dramatically improve our health.
So what are these major differences you might be asking?  Well think of our basic chicken which many of us consume regularly, who doesn't love chicken unless you're vegan or vegetarian.  This delicious dish is categorised in the acid list; who would have thought?  That also applies to the faithful banana.  I have always heard that the banana is a complete food containing almost every vitamin and mineral.  What more could one ask for especially with children who are fussy eaters. I know I for one enjoy eating a banana or any fruit for that matter.  So what's all that doing to my body you might be asking?  Not too much if some of these foods are eaten sparingly so let's not get carried away here.
I gather that some of the better items for our health live in the alkaline bracket.  Things like celery, almonds, green beans, cauliflower, carots, potatoes and tomatoes to name just a few.  Oh and by the way, if you eat an unripe banana then that is all right too.  Interesting facts wouldn't you agree?  But how many of us would really be prepared to forgo all the foods we've enjoyed for most of our lives?  Can you say sincerely that you'd be prepared to give up coffee, meat, fish, chocolate and that blissful glass of wine at the end of a busy day?  You've got a whole lot more willpower than me if you can.
So what does all this mean, do we go acid or alkaline to improve our health.  I would suggest it's like most things in life, follow this way of eating in moderation. If you suffer from serious health problems it could well be the right thing to do but if like most of us you simply wish to tweak the way we eat then check out the acid/alkaline dietand decide for yourself exactly which foods you're prepared to toss from your own personal daily diet.
