Too Much Sugar & the Brain

Overeating, poor memory formation, learning disorders, depression  – all have been linked in recent research to the over-consumption of sugar. And these linkages point to a problem that is only beginning to be better understood: what our chronic intake of added sugar is doing to our brains.

While a healthy diet would contain a significant amount of naturally occurring sugar (in fruits and grains, for example), the problem is that we’re chronically consuming much more added sugar in processed foods.

Research indicates that a diet high in added sugar reduces the production of a brain chemical known as brain-derived neurotrophic factor (BDNF). Without BDNF, our brains can’t form new memories and we can’t learn (or remember) much of anything.

What these and other studies strongly suggest is that most of us are seriously damaging ourselves with processed foods high in added sugar, and the damage begins with our brains.  Seen in this light, chronic added-sugar consumption  is no less a problem than smoking or alcoholism. And the hard truth is that we may have only begun to see the effects of what the endless sugar avalanche is doing to us.
