Take everything I say as just one person’s ideas. I’ve researched these things a lot, but I certainly don’t know what is right for an individual since that will vary from person to person. With that said, my response to your question follows.

Protein quality is probably only an issue for vegans. Most animal protein is good quality. Dairy is generally very good, in my humble opinion. Eggs are also quite good if you eat eggs. Fish is good. I think there’s good evidence that suggests that polyunsaturated fat is a thyroid suppressant, so I’d probably give preference to non-fatty fish instead of fatty fish since fish fat is high in polyunsaturated fat. But this is probably only an issue if you’re eating fish daily. (In which case, frankly, I’d be more concerned about the contamination with heavy metals (and halides like bromide) than polyunsaturated fat.)

There are various views on actual protein requirements. I’ve seen Matt suggest that protein requirements may not be that high. Personally, I have seen benefits from increasing protein intake – not ridiculous amounts, but more than I used to. So it is possible that the quality of protein may not be as much of a factor as the quantity. US government recommendations are usually for just under 50 grams per day. I’d expect that for a chronic dieter with hypothyroid symptoms then refeeding protein requirements are probably higher. I suspect that most people in such a state will probably need 70+ grams of protein a day. Many people will need 80, 90, 100 or more grams per day. It’s highly variable.

Of course, there are plenty of factors that can contribute to hypothyroidism. Insufficient calories, carbohydrates, or protein can do it. So can excessive polyunsaturated fat. So can insufficient sleep. So can excess, particularly chronic stress. So can excessive goitrogens including thiocyanates and other food-based goitrogens or environmental exposure to competing halides such as chlorine, fluoride, or bromine. So can excessive estrogen.
