Tortoise Group Information Sheet # 4
COMPARISON OF NUTRIENT VALUES IN FOODS
We recommend a diet with no vegetables, such as commercial produce. A diet of vegetables is not complete. Instead, offer MegaDiet tortoise chow. It provides all the needed nutrients and fiber. Also, grow dandelions, grass, and ornamentals (See Information Sheet # 21). Read the section on Food in the Tortoise Group booklet, Desert Tortoises, Adoption and Care. Most deficiencies are from diets low in Vit. A, calcium, protein, and fiber. The challenge is to provide these nutrients without giving excessive sodium, or more phosphorus than calcium. A calcium to phosphorus ratio of 2:1 is good. MegaDiet fulfills all requirement. Do not add supplements.

Special Warnings
- SODIUM. Most fresh vegetables contain only 1 to 10 milligrams of sodium per 100 grams of the food. Canned vegetables average 236 mg per 100 grams!! Sodium is added to some frozen foods. Avoid: canned and frozen vegetables, dairy products, breads, and celery.
- SPINACH has nutrients but also contains OXALIC ACID. Oxalic acid binds calcium making it UNAVAILABLE to the system. Avoid spinach. Also avoid beet greens and Swiss chard for the same reason.
- BROCCOLI, KALE, COLLARDS and MUSTARD GREENS (of the cabbage family) have valuable nutrients but depress the thyroid. Goiter can develop from heavy use of the cabbage family.
- NO CAT FOOD OR DOG FOOD. They may cause digestive problems because the fiber content is too low for tortoises.
- NO SWEET FRUIT OR CORN. The sugar in these foods predispose desert tortoises to intestinal parasites.
- NO FROZEN VEGETABLES especially for young tortoises. Some nutrients are lost when foods are frozen. Frozen carrots and broccoli are rubbery and corn is not healthful because of the sugar. Some frozen vegetables have added sodium.
The Tortoise Group booklet, Desert Tortoises Adoption and Care is available at veterinary hospitals in the Las Vegas area and public libraries throughout Clark County. See Tortoise Group website
MegaDiet, the complete tortoise chow is the recommended food. It is available from Tortoise Group.
