This might sound extreme, and I guess it is, but it's a genuine question. I have a book - Real Food for mother and baby, by Nina Planck - that recommends the following:
'your baby can eat unrefined sea salt to taste'
'if you start early... i highly recommend lightly cooked egg yolk with a pinch of salt...'
'raw ground beef or lamb with olive oil and salt is a good dish for babies'
It's an otherwise commonsensical book but this seems to run contrary to all the advice I've read anywhere. Thoughts?
