At first glance, Spinach may seem a good gutload choice. And it is, in small amounts from time to time. Spinach is a good source of Fiber, Protein, pro-formed Vitamin A, Vitamin C, Vitamin E, Vitamin K, Thiamin, Riboflavin, Vitamin B6, Folate, Niacin, Zinc, Calcium, Iron, Magnesium, Phosphorus, Potassium, Copper and Manganese.
HOWEVER, Spinach (especially older leaves) is on all the Oxalic Acid and Goitrogenic lists. Meaning Spinach could interfere with calcium, iron and iodine absorption /uptake. So, best to limit your use of it in gutloading.
If you're looking for alternate leafy greens to include in your gutload, have a look at this list:
