Who said anything about "produced in a factory"? Monkeys eat mostly ripe tropical fruit. The monkey chow here probably includes palm oil and soy.
Specific toxins that accumulate in tissues over time and are known to contribute to premature aging in mammals include certain fatty acids and excess iron intake, for examples. In excessive amounts they are "toxic."
I don't see what is remotely "woo" about this. The whole calorie restriction idea has been pretty well debunked as far as I'm concerned. Whenever it's looked at more closely it's a matter of food quality. Animals with the highest metabolisms among their peers are actually healthiest and longest lived.
