nutritional value

April 17, 2010 in Uncategorized

As my daughter is getting older, I will have a lot of questions....Can we trust the amount of the protein written in the package? For example, I was looking a usual cookie (actually, eating it!) , and it was written that it contained 0,5gr per item (that is, if I,m not mistaken half an exchange). Is this true? Do you trust companies about this?

    The protein amounts on packages are estimates. For example, something listed at one gram can have up to 1.4 grams of protein in it. It can be a good approximation to know if a food is “safe” for the diet once your child is older. However, if you don’t have accurate information, make sure you overestimate. 1 gram of protein = 50 mg of phe, but nutrition labels can list anything up to 70 mg of phe as 1 gram.

    If you have the low protein food list (a binder list of phe in a bunch of different food items) that is your most accurate way of counting. The 1 gram = 50mg phe is a fairly accurate estimation, but different types of food have different concentrations of phe per each gram of protein also, I’ve been told. So protein is made up of a bunch of different amino acids. Phe is one of them. So in a bag of chips that says 2 grams of protein, the percentage of phe might be different than the concentration in 2 grams of protein of say chocolate. (basically, any two foods). I might be wrong on this, and there are dietitians on here that might be able to correct or clarify. (Hunter, where are you?!) But my clinic has always recommended counting mg phe and not grams of protein because it so much more accurate because of the variation of the composition of the protein as well as the rounding issues that Sarah mentioned.

    I’m here! Kristi, you are absolutly right. Virginia Schuett and her team created a food list back in 2002 and are updating it as we speak. These are the most accurate measures as they take both the ingredients AND the grams of protein (rounded to the nearest tenth when companies provide this information) to get a better idea. As kristi and sarah said, the g listed on the label can be used to estimate ~50 mg/1 g Pro, but these is not the exact measurement. In my personal opinion, I use Ginny’s food list (The Low Protein Food List for PKU) as my go-to and if there is a discrepancy, I look to the book. Stay tuned for the updated list due sometime this summer. Sorry for the delay (Kristie!) And yes, I personally count mg of PHE not only because it is a more accurate measure but also because I have an extremely low tolerance (~3 g Pro/d) which would be very difficult to count using just grams (with decimals and all of that). Other countries count fruits and veggies as free and give a certain g of protein to adhere to… just a different way of doing things! Their patients levels are within rang as are ours, so for me sticking with mg is what works! Hope this helps
