In fact, there are two potential mechanisms through which refined sugar intake could exert a toxic effect on mental health.
First, sugar actually suppresses activity of a key growth hormone in the brain called BDNF. This hormone promotes the health and maintenance of neurons in the brain, and it plays a vital role in memory function by triggering the growth of new connections between neurons. BDNF levels are critically low in both depression and schizophrenia, which explains why both syndromes often lead to shrinkage of key brain regions over time (yes, chronic depression actually leads to brain damage). There's also evidence from animal models that low BDNF can trigger depression.
Second, sugar consumption triggers a cascade of chemical reactions in the body that promote chronic inflammation. Now, under certain circumstances (like when your body needs to heal a bug bite), a little inflammation can be a good thing, since it can increase immune activity and blood flow to a wound. But in the long term, inflammation is a big problem. It disrupts the normal functioning of the immune system, and wreaks havoc on the brain.
Oh yeah, don't take his sugar away!! He has a real psychological need for it. It would be like detoxing from heroine or alcohol. Even more serious biochemical imbalances would come up. You don't want to be around when that happens.
