Basically all the white stuff is made of complex carbohydrates-- rice, white bread, white pasta, biscuits, cookies, cakes, etc. And notice that all of these foods are processed foods (meaning they are no longer in their natural form).
The largest hailstone in terms of diameter and weight ever recorded in the United States fell on July 23, 2010 in Vivian, South Dakota; it measured 8 inches (20 cm) in diameter and 18.62 inches (47.3 cm) in circumference, weighing in at 1.93 pounds (0.88 kg).
Just looking at the pictures, it would appear that this stone has broken the record for diameter and circumference that was previously set in Aurora, Nebraska in 2003. The 2003 hailstone was 7 inches in diameter, having a circumference of 18.75 inches. The new hailstone would appear to have a maximum diameter of around 8 inches and a circumference of about 19 (if the beginning of the tape measure is zero).
