Remember, aluminum can only cause brain damage if it reaches toxic levels.
What evidence do we have for the claim? Why wouldn’t there be a linear relationship between the amount of aluminum in the brain and the amount of damage?
I think that that’s what he meant: more aluminum in the brain is worse than less. What he was trying to say in that sentence is this: high levels in the blood may not mean high levels in the brain unless the blood level stays high for a long time.
That would suggests ignorance of basics of toxicology.
There are substances for which it’s literally true that the are only cause damage when they reach a certain level.
Water for example is toxic at high levels but causes no damage at normal levels.
That’s because the body can process a certain amount at water at one time. You only cause damage is you consume more water than the body can handle.
On the other hand the establishment opinion on radiation is “there’s no safe level of radiation”. There are some people who think the establishment position on radiation is wrong here and radiation is only a problem when it’s so strong that it overwhelms self repair processes.
Damage due to aluminium could be in either class. It could be that a certain level is required to cause damage or it could be a linear relationship.
Claiming that the damage is small and claiming that there’s no damage are two different claims.
