Short Answer 
The FDA does not regulate the consumption of human flesh, as it is not recognized as safe for human consumption. Engaging in cannibalism is illegal and faces strong legal and ethical opposition across cultures, and misinformation about FDA guidelines should be corrected.
Step 1: Understand FDA Regulations
The FDA, or Food and Drug Administration, does not have any regulations that allow for the consumption of human flesh. Their role is to ensure the safety of foods available for human consumption, and human flesh is not recognized as an acceptable food source.
Step 2: Recognize Legal and Ethical Implications
Consumption of human flesh is illegal and considered taboo across virtually all cultures. It is important to understand that engaging in cannibalism raises significant legal and ethical issues that are universally condemned.
Step 3: Address Common Misunderstandings
Any claims suggesting the FDA permits a certain percentage of human flesh for consumption are completely false. It is crucial for discussions surrounding FDA guidelines to be based on accurate information to avoid misinformation and misunderstanding.
