No, not at all. It is really quite clear to me. The glucose is the energy 
and the vitamines are essential cofactors for the metabolism. Glucose 
is very fast taken up into the blood and is the only substrate the brain 
can metabolise. If you go under the 5 mM glucose border you will 
start to feel dizzy and distracted and it takes some time for your 
brains to recover.  Normally your liver takes care of the 5 mM. If it 
reserves are not sufficient you will start to feel hungry. So, you will 
need to eat. Everybody knows that you can't study with an empty stomach 
nor with a full stomach. Doing this way, with the glucose, you can 
permit to eat little to keep your intestins busy and yet you give 
enough energy for those parts of your body that are really working while 
you are studying: your brain. Together with the glucose you take up a lot 
of wather which is a good carrier for the metabolites. I don't know how 
you study, but have you ever calculated the effective 
time per day that you were studying, without breaks or luchbreak? The 
pure time that you are studying at your desk. In this way I could study 
upto 16 effective hours per day. In this way information is soaked into 
my brain. It works very good for me and for a friend with who I studied 
It is not very scientific to call this bullshit. As a biochemist I can 
say that it has a biochemical and fysiologic basis.
