2.3 grams of protein
3.8 grams of dietary fiber
23.6 grams carbohydrates
21,907 international units vitamin A (438 percent DV)
22.3 milligrams vitamin C (37 percent DV)
0.6-milligram manganese (28 percent DV)
0.3-milligram vitamin B6 (16 percent DV)
541 milligrams potassium (15 percent DV)
1-milligram pantothenic acid (10 percent DV)
0.2-milligram copper (9 percent DV)
30.8 milligrams magnesium (8 percent DV)
1.7 milligrams niacin (8 percent DV)
