Sheba pates and premium pates info.

Since this info. was missing from Dr. Lisa's food chart for Sheba food, I tried contacting the company to obtain info. I asked for percentage of calories from protein, fat, and carbohydrates and how many milligrams of phosphorus are in the food per 100 kcal.

Here's the response (they gave me values in Grams):

"Dear Megan,

Thanks for taking the time to contact us. Unfortunately a dry matter basis is unavailable for this product. However, we can tell you that our SHEBA® premium pate foods contain approximately 2.8 grams of phosphorus per 100 kcal of M.E. and the SHEBA® premium cuts foods contain approximately 3.6 grams of phosphorus per 1000 kcal of M.E.

We do not formulate any of our SHEBA® premium cat foods to meet medical dietary needs so, please, consult with your vet before feeding..."

so, 2.8grams/100kcal = 2800 milligrams /100kcal, which cannot be correct? I'm sorry, I suck at math. I'm missing something. And why did they give per grams per 1000kcal for the premium cuts?

somehow, i'm wanting to arrive at 280 and 360... aren't I?!

 

@Elizabeth and Bertie helped me to work something similar out so she might be able to help you too

 

Try using this online calculator with the can label info. That'll get you partway there.

 

thanks BJ; yes, I had already done that for the protein/fat/carbs, but I was mostly concerned w/ the phosphorus level. And I'm just confused on how to arrive at a comparable number to Dr. Pierson's w/ the info. they gave me.
for one food it is expressed as grams/100kcal, the 2nd one is grams/1000kcal. And when i convert grams to milligrams, it is WAY higher than the levels on any of the foods on Dr. Pierson's chart but that can't be right. If i multiply the gram values provided by 100, i get values in line w/ Dr. Pierson's chart. But I don't know that that's the right thing to do?!

 

I'll see what I can figure out.

Start by putting them on the same basis, either per 1,000 or per 100:
SHEBA® premium pate: 20.8 grams of phosphorus per 1000 kcal of M.E.
SHEBA® premium cuts: 3.6 grams of phosphorus per 1000 kcal of M.E.
OR
SHEBA® premium pate: 2.08 grams of phosphorus per 100 kcal of M.E.
SHEBA® premium cuts: 0.36 grams of phosphorus per 100 kcal of M.E.

I'd e-mail back and confirm the wide discrepancy in amounts.

 

Hi,

With wet food, in order to work out the phosphorous content on a dry matter basis you need two things. Firstly you need the moisture content of the food. Second you need to know the percentage of phosphorous in the food.

Regarding the percentage of phosphorous in the food the 'grams per 100g' will be the same as the percentage. So BJ's figures here can be translated to percentages:
"SHEBA® premium pate: 2.08 grams of phosphorus per 100 kcal of M.E." = 2.08%
"SHEBA® premium cuts: 0.36 grams of phosphorus per 100 kcal of M.E." = 0.36%

The second figure looks credible to me, the first one doesn't. That looks way too high and it may be that they've sent you the wrong info? Either that or they've actually sent you the dry matter percentages; in which case the first is at the high end of the scale and the second is delightfully low (similar to prescription cat foods ).

Anyway, the calculation is this:
First, deduct the moisture content of the food from 100%. That will give you the total dry matter percentage.
Second, grab a calculator and do this: Divide the phosphorous by the dry matter, and then multiply by 100. (Alternatively divide the phosphorous by the dry matter '%')

Or....you can make life easier and put the figures into this nifty dry matter calculator here :
