Question: what is the difference in the nutritional value between the 3 grades of eggs?
Answer: According to the USDA guidelines, a Grade AA egg has “whites that are thick and firm; yolks that are high, round, and practically free from defects; and clean, unbroken shells.” Grade A eggs are basically the same except with whites that are only “reasonably” firm. ... They're just eggs at the end of the day.
