You have a trial or test that has been conducted that shows that claim, or do you routinely make up data and facts for things you know nothing about?
How about mechanism of action--what properties do the avocadoes, egg yolks and Vitamin D combo have that improves cognitive decline in Alzheimer's patients?
I didn't say it was some kind of magical combo, and I don't need a stupid pharma "trial" to prove anything. Just see how an entire generation of Americans who were told NEVER to eat those things, among other brain-critical fats, saw a fivefold increase in dementia.
