Answer:
Blood Brain Barrier(BBB)
Explanation:
This is a biological interface of special endothelial cells of astrocytes, pericytes , capillaries, neurons and other structures, acting as a physical barrier or gate separating the Central Nervous system from the peripheral blood circulations. Thus it formed a tight junction serving as a physical barrier to selectively regulate the entrance of substances from the cerebral blood flow into the brain, therefore maintaining homeostasis of the brain.
From above any substances absorbed into the blood stream irrespective of the mode of entry are transported through the BBB, and are selectively regulated to enter the brain cells by the BBB's interactions with the blood vessels, hormones etc.
Basically it allows the passage of nutrients, a few drug, hormones and resists certain toxins and pathogens for the brain homeostasis.

Answer:
Well you already know the answer is false but I want to elaborate on this for other people who have the same / similar question.
The main source of meat, milk and eggs in most, if not all, countries are Factory-Farms, which are highly abusive, cruel industries that provide meat to around 99% of business I assume haha. A lot of businesses that claim to use "humane" practices of getting meat, dairy and eggs are not true, there is really no human way to get meat or dairy (you can humanely get eggs though factory farms don't) you can read more about this stuff on SentientMedia (graphic content warning)
Farms around the world though use different ways of harvesting (by hand, by machine etc.) planting, different kinds of crops, different ways of waters, what kind of land they plant their crops in.
Hope this helps
have a nice day((:
