Regarding poisons themselves, they all depend on how much you ingest. How much salt do you eat? Three pounds a day? Salt is a poison and if you eat too much you can get sick and die. Almonds contain cyanide. People eat almonds without dying. Does that mean cyanide is a beneficial substance in all quantities?
Regarding allergens there are similar dynamics. Someone allergic to cat dander will be able to walk down a street where cats have been. But they may not be able to sleep well in a bed that is normally occupied by 100 cats. Or consider peanuts. Someone allergic to peanuts will not do well eating a peanut butter sandwich. But most of them can handle being in the presence of peanuts, despite hysterical media reports of people dying after kissing someone who had recently eaten a peanut, all stories of which were discredited.

So people are claiming "It is in human breast milk and beef and eggs!" Yes, 22mg to 33mg of glutamates per 100g.
Up at the top, parmesan is 1200mg per 100g. How much parmesan do you eat exactly? Is this a cheese that you slice off in giant wedges and gnaw on? Or is it grated and used like a spice in relatively small amounts by weight?
