Are there any hadiths about salt and meat, and is "Beware of the two whites: salt and sugar" an authentic hadith?

Many prophetic hadiths have been reported about meat. The Prophet, peace and blessings be upon him, loved meat, especially the foreleg and the front part of the sheep. Hadiths have also been reported about salt, including the comparison of the demise of those who plot against the people of Medina to salt dissolving in water, and the comparison of the scarcity of the Ansar to salt in food. As for sugar, it was not mentioned in the hadiths except in the description of the water of the Hawd (basin) as being sweeter than sugar. And the saying "Beware of the two whites" is not a hadith.
