You definitely don't want low levels.
I'd rather have lower than higher levels, since lower levels seem to cause milder symptoms, compared to toxicity (which seems to cause more severe problems, which may be harder to detect anyway, since it isn't fully understood what levels are actually toxic in all these ways).
Generally, I get the impression that deficiencies in some micronutrients become more severe due to excesses in others, or too much of one causes another to become toxic (like how they say glutamate concentrates iron in the brain), and overeating would result in perhaps numerous imbalances, rather than eating less with fewer micronutrients involved (as long as they're all in the diet in some amount regularly). Looking at the
case report of an obese person who fasted for more than a year straight, they didn't see any severe malnourishment occur even then, which seems like an example of how overeating could actually cause more of an imbalance than undereating (where an obese person may typically have more problems with eating too much over a year, compared to not eating at all).
Anyway, I wasn't talking about efforts to restrict iron or free glutamate (besides for those who may have dementia or a metabolic syndrome). It seems that these things may add up with supplementation, food fortification, and flavor enhancement though.
I just hadn't read anything about iron being associated with Alzheimer's before, and then wondered if it was related to glutamate, since iron was thought to affect the Japanese lately (who are more well known for MSG in the diet, which was also associated with Alzheimer's). So putting two and two together might not add up to a great diet there (but they mentioned other dietary factors which may contribute to their increasing memory problems as such). MSG is made from corn syrup, coincidentally (that was mentioned as another possible cause of memory problems, along with fructose)... I wonder what they had for dessert.
