Cool Way to Remember the 9 Essential Amino Acids

what it claims

The community emphasizes the importance of consuming complete proteins, with a marked preference for animal-based products (notably eggs) as the ideal source, providing the most balanced amino acid profile for humans.

The notion that animal proteins possess an amino acid profile closer to human needs is supported by nutritional science, which often uses the egg as a reference (Protein Digestibility Corrected Amino Acid Score, or PDCAAS). Research confirms that these sources are considered "complete" because they provide all nine essential amino acids in adequate quantities, unlike many plant sources that can be limiting in certain amino acids (such as methionine or lysine). However, the claim that it is imperative to consume these proteins in animal form to be healthy is nuanced by observational studies showing that the complementarity of plant proteins over the course of a day is sufficient to meet these needs. The "perfect ratio" aspect is therefore physiologically true for the egg, but the requirement for a single source to obtain this ratio is an oversimplification. There is a clear consensus on the necessity of providing these nutrients, but a diversity of opinions on the source required to achieve this. The forum converges on the practical appreciation of mnemonic devices to retain these essential components.

What the graded evidence says

Evidence
B

Linked to, not proven to cause.

Effect
cardiovascular disease risk by egg / dietary-cholesterol intake (pooled cohorts) — up to ~1 egg/day not associated with CVD risk overall (pooled HR near 1.0); a separate cohort found each additional ~300 mg/day dietary cholesterol and each half-egg/day associated with modestly higher CVD and all-cause mortality
Measured on
generally healthy adults; some signal of greater sensitivity in diabetes

What’s uncertain

This is association data (cohorts), not proof, and it's slightly mixed: most analyses clear moderate egg intake, one large one flags dietary cholesterol. 'Up to 7 a week is harmless for everyone' is a fair rule of thumb for healthy people, with a gentle caveat for diabetes.
