I would limit it, or at least offer other items.
From the Caresheets...
[Gutloading ingredients should be higher in calcium than phosphorus, as well as low in oxalates and goitrogens. High phosphorus levels inhibit calcium absorption.]
[Each time you [choose ingredients] get two or three options, then rotate them for something else next time. Make sure you wash all produce to eliminate pesticide residues and cut off the peel of fruits and vegetables as they have waxes and pesticides you can't wash off.]
Suggested Ingredients
Best - These gutloading ingredients are best because they are highest in calcium, low in phosphorus, oxalates and goitrogens. They should be the primary components of your gutload:
mustard greens, turnip greens, dandelion leaves, collard greens, escarole lettuce, papaya, watercress and alfalfa.
Good - These gutloading ingredients are good because they are moderately high in calcium and other vitamins/minerals. They should be used in addition to those from the previous category:
sweet potato, carrots, oranges, mango, butternut squash, kale, apples, beet greens, blackberries, bok choy and green beans.
These fresh fruits and vegetables can be combined with dry gutload mixes or home made mixes for optimal well-rounded nutrition. Dry ingredients can include:
bee pollen, organic non-salted sunflower seeds, spirulina, dried seaweed, flax seed and organic non-salted almonds.
Avoid These Ingredients
Avoid these gutloading ingredients because they are low in calcium, high in phosphorus, goitrogens or oxalates: potatoes, cabbage, iceberg lettuce, romaine lettuce, spinach, broccoli, tomatoes, corn, grains, beans, oats, bread, cereal, meat, eggs, dog food, cat food, fish food, canned or dead insects, vertebrates.
My veiled also loves baby Kale and Spinach but I try to limit the amount I give to avoid issues.
