I would stay away from most things that's pre-packaged. If you look at the list of ingredients, it will blow you away......They put some much crap into it to "improve the flavor" and to increase the shelf life not to mention the deceitful marketing that's tailored to lure the young ones in...........

Bottom line, buy fresh wholesome ingredients and make your own at home, leave their crap on the shelves, eventually when sales fall they'll get the message.......Much cheaper and WAAAAYYYY HEALTHIER !!!!!!!!

Although we eat reasonably healthy food I 'allowed' my son to have a processed and rather sweet cereal most mornings as he was so fussy about every other thing offered.   A recent visit with a naturopath has revealed that his kreb cycle has been disrupted.  In other words he no longer converts carbohydrates into blood sugars as he should.  This explains his poor concentration and mood swings. 

However it is fixable with a diet of no sugar, no carbs apart from rice, no sweet fruit or fruit juice.  We will eat like Chinese, mostly vegies and meat for 6 weeks plus magnesium, chromium, pottasium, multi B's and protein powder.  I will join him and lose weight, he is already super light but it will be wonderful to have him leaning well again. 

You may have heard about the study where they fed 3 groups of lab rats as follows:  Control = rat food, group a = corn flakes, group b = corn flakes box...YES, THE BOX!

The first group to die off was the corn flakes.  All those rats died BEFORE any of the rats who ate the box.  Even if you take the best grains and you slurry them up and extrude them (aka make cereal) you destroy the molecular structure of the grain, possibly doing more harm than good.
