Using cronometer.com, here's the amino acid composition of a typical daily serving of approximately 30g protein from various sources:
Milk
Cystine: 0.2g
Methionine: 0.8g
Tryptophan: 0.4g
Cheese
Cystine: 0.2g
Methionine: 0.8g
Tryptophan: 0.4g
Chicken
Cystine: 0.4g
Methionine: 0.9g
Tryptophan: 0.4g
Egg
Cystine: 0.6g
Methionine: 0.9g
Tryptophan: 0.4g
Beef
Cystine: 0.3g
Methionine: 0.8g
Tryptophan: 0.2g
Gelatin
Cystine: 0.0g
Methionine: 0.2g
Tryptophan: 0.0g
If we rank these protein sources from best to worst from a thyroid-perspective we get:
Gelatin > Beef > Milk & Cheese > Chicken > Egg
It seems beef is a notable exception to Peat's statements that muscle meats are thyroid-suppressive. In fact, beef appears to be better than milk, and is equally low in PUFA.
It seems to me, your thyroid would be in better shape if the bulk of your daily protein came from a combination of gelatin and beef, rather than dairy.
And egg is just terrible.
