The iguanas diet should contain 2 times as much calcium as phosphorus. That means the overall diet, not the individual items.
As long as you are feeding a variety of foods, there aren't enough goitrogens in mustard to cause a problem. For instance, broccoli and cauliflower are both high in goitrogens as well, so it would probably be best to avoid using them with mustard.

Oxalates are substances that bind with calcium inhibiting the way the body metabolizes it.
Goitrogens inhibit the uptake of iodine, affecting the thyroid.

Well, that's what the GIS food chart says it is. seems weird tho...I guess I can look and see what the nutritional values are on the other vitamins and minerals. **nods** I'll get back to ya on that. ;D

Cacti are listed as fruit which is supposed to be a minimal percentage of the ig diet...... but it has a good calcium to phospohorus ratio (2.3:1) with a low potassium level too. It's good I've only used it once cause it was SUCH a pain to clean!

Thanks Steph. I found some clip art on the net, but I haven't decided if I should go that route. When I put the clip art in, it made it look kinda cheesy. (I'm trying to appear intelligent and don't have much to work with in the brain department as is) ;D I have a list of around 65 food items at present. Many of which I couldn't find pics of at all. I'll keep your offer in mind and your offer of help is MUCH appreciated! :* V- I am trying to use sources such as USDA so I don't require permission from numerous entities. It becomes too complicated trying to sort out what pic came from where etc.

I just now found Yucca Root. It's Ca>P is low (.6:1) with Potassium being relatively high. (457) I'm thinking occasional on that it too....

I've been looking for kabocha and yucca. Neither is listed on the USDA site I'm using (and I've tried several different names) I'm not giving up tho. The asparagus Ca>p is .5:1 with 202 mg of Potassium (K) That rates higher than broccoli and cauliflower. I'm getting close to having the food chart done. I can't get permission to use anyone's graphic tho, so I guess I'm gonna have to post it without them. I'd really like for ya'll to be able to look thru this. It's very interesting (to me anyway) ;D

Patrick, I think you are missing the point. Are you understanding that the Potassium prohibits proper absorption of Calcium? Sweet potato contains nearly TWICE as much Potassium as ANY fruits and veggies I have researched. (per 100 grams) Glancing over my information, the four food highest in Potassium are: Parsnip: 375 mg brussel sprouts: 389 mg bananas: 358 mg Sweet Potato: 816 mg So see, you mentioned feeding sweet potato with parsnips. Thats almost as bad a combination as you can get concerning the pottasium level. Not only that, but the yam's Calcium level is relatively low as well; resulting in a double whammy for the iguana. So yes, variety is the key. But I stand by my recommendation that sweet potato be removed from that variety. Of course, sweet potato isn't gonna "kill" your ig, but I'm thinking our goal here is to provide it with the best food we can.

yep...110 grams = 3.5 oz.....so no more than we feed of the squashes it would still be ok. I'm nixing the sweet potato tho I was taught that is a staple veggie....learn somethin new all the time I'm so proud of us! lol

ya know what? it's the daggum sweet potato that we need to eliminate..not the squash!! Its WORSE than bananas if we compare potassium to Ca to P values. lookie here....
(per 100 Gram) .............Potassium......... Ca to P......Potassium: Ca to P ratio
yam.............816............point 31/1.........2632:1 butternut.......352............1.45:1..............242:1 acorn............347...........point 92/1..........377:1 banana..........358...........point 23/1.........1556:1 parsnip.........375............point 51/1..........735:1 papaya..........257............4.80................53:1 turnip greens...296...........4.52..................65:1 collard...............296.........14.5................20:1
Whaddya think??

Posted by: prism_wolf Between the sweet potato and the butternut squash...use one or the other, but not both. You can swap out the parsnip for cilantro for a bit of variety, too...
Posted by: Tesa Veronica, I use sweet potato and butternut together. What info am I missing that tells me why I shouldn't?
I use several veggies every day. For instance, I might use one small sweet potato, one parsnip, a handful of snap peas, a wedge of acorn squash, a slice of butternut, and a small slice of mango. I run them all thru the food processor so that they are slightly larger than a grain of rice. Thrasher gets about a half cup of this mixture and all the salad she wants every day.

Both are very high in potassium.
Summer Squash
Nutritional Value: Low in calories and contains a good supply of vitamin A and potassium, 94% water when raw. A one-half cup serving of cooked summer squash will provide 10 calories, .45 gm protein, 2.2 mg carbohydrates, no fat, 1.7 gm dietary fiber, 315 IU vitamin A and 192 mg potassium.
SWEET POTATO (based on a medium baked sweet potato) Calories-117kcal Carbohydrate-28 g Protein- 2 g Fat-0.1 g Dietary Fiber-3 g Calcium-32 mg Iron-.05 mg Magnesium-23mg Manganese -0.6mg Potassium -397mg Vitamin C - 28 mg Vitamin A -24877 IU Vitamin E -0.3 mg_ATE
Winter squash, 1 squash (raw, acorn) Calories: 172 Protein: 3.4g Carbohydrate: 44.9g Total Fat: 0.43g Fiber: 6.46g *Excellent source of: Magnesium (138mg), Potassium (1,495mg),Vitamin C (47mg), and Vitamin A (1,454 IU) *Good source of: Calcium (142mg)
Potassium, as we know, keeps the ig from metabolizing calcium properly. Did you notice the calcium level in the acorn squash!! It's awesome! For an MBD ig this would be pretty good, though I'd need to look at the overall Ca: P ratio. Posted by: Tesa if the pottasium level in the acorn squash is too high.... wouldn't it offset the calcium level anyway?
also: Ive been working on a table of nutrional values (havent got very far yet) but according to USDA.....the potassium level in both acorn and butternut squash (per 100 grams) is comparable to that in mustard greens, dandelion greens, and watercress. The Calcium to PH ratio for Butternut squash is about 1.5 : 1 for acorn squash it is right at 1:1
I wonder how much our sources differ from each other.......?
Posted by: Tesa maybe its because your source is going by the whole vegetable and Im using 100 grams........?? Posted by: Dominick Hi Ladies-
I find this current dialogue very enlightening. Please continue with this important discussion. There are some interesting things I'm learning here.
Nice work on both your parts.

Exactly right. We don't want to offset the calcium.
Just as we don't feed to much banana for the same reason, with the other greens already being comparable in potassium (besides collards), this will upset the ratio to an even higher degree.
Collard greens only has 169 mg of potassium per 100g. Acorn squash has 347 mg per 100g. Butternut squash has 352 mg per 100g. Acorn and butternut squash holds twice the potassium. Adding both of these foods at the same time adds double the amount of potassium that just one of those would.
Sweet potato is not coming up in a raw state on the USDA food chart (comes up in baby food...go figure), but using it's cousin the yam, there is a very poor Ca: P ratio with the Potassium level being 816 mg per 100g. This is putting the potassium level at a ball park figure of 1515 (not getting the exact levels for the SP) IF you were to use the whole 300g used between the two squashes and the sweet potato.
One of the reasons collards is such a good food even though the Ca: P ratio is like 14:1 is because it helps offset the other foods that are a bit lower in calcium, and give a boost to the foods that hold too much in oxalic acids...such as the collard greens themselves.
When we add too many other foods that are high in potassium (or oxalates), we start to take away the buffer and add more blockers in the calcium absorption process.
The other amounts I used were in one cup servings with the exception of the acorn squash which took into acount the whole squash of an undetermined size.
Using the USDA data selections give a more accurate reading, and it still shows that the above mentioned "accessory foods" to an iguanas diet are very high in potassium.
If we warn people to use bananas very spareingly with a potassium level of 358, which also has a horrible Ca: P ratio, would it not then be wise to use the same rule for using all the foods in question with the same care, though the Ca: P ratios are better by a small amount in the foods in question?
Actually I have learned a bit more from this line of questioning the foods we feed. The squashes, sweet potato and yams have always been a favorite additive that helps bulk up the underfed ig by packing on extra pounds a bit quicker as well as being "eye candy" for the ig.
Any other thoughts on this? Jeez...this is like a whole topic in itself! Can we make a seperate thread for this?
Posted by: Tesa I'll give this more thought after Ive had coffee

Yep...escarole (endive) is good. The Calcium to Phosphorus ratio is around 2 to 1. Its a bit high in oxalates and goitrogens, but when used with the other greens it shouldn't pose a problem.

You should probably add more greens and cut back on the veggies. Try turnip, mustard, and dandelion greens. I feed mine about 70% greens and 30% veggies.

Yes, that's quite normal. Just like us, some days they are hungrier than others. As long as it all balances out, there is no need for you to be concerned.
