“Fructose increases the rate of iron absorption through the gut. Increased iron in brain reduces insulin sensitivity and reduces the rate of amino acid absorption into the brain neurons. Vertebrate neonates need to absorb sufficient glutamate into neurons to initiate the excitotoxin apoptosis in excess brain cells. Autism kids have 67% more brain cells than normal adults. The excess brain cells create the “white noise” that interferes with the kids ability to function.”
What does this have to do with a zinc deficiency?

"Micronutrients are nutrients required by humans and other organisms throughout life in small quantities to orchestrate a whole range of physiological functions, but which the organism itself cannot produce.[1] For people, they include dietary trace minerals in amounts generally less than 100 milligrams/day[citation needed] - as opposed to macrominerals which are required in larger quantities.
The microminerals or trace elements include at least iron, cobalt, chromium, copper[2], iodine, manganese, selenium, zinc and molybdenum. Micronutrients also include vitamins, which are organic compounds required as nutrients in tiny amounts by an organism.[3]"
