Here is a quick tutorial about how to use the android app PKUDietBook’s LowProteinFoodList feature. Sorry for the qualify of the video.


Invalid Username Error

Some of you have run into a invalid username error while using the Diet Record Management function on your mobile device. Please note that, currently, there are two credential settings in the applications, one is for search and one is for diet record upload. There is a default username/password came with the app allowing the basic search function under Low Protein Food List, while the diet record management requires a valid username and password in order to upload your diet records to the www.mypkudiet.com web site so your diet records can only be seen by you. you can register an account on the home page of www.mypkudiet.com. Registered user has many other benefits using the web site from which you can enter additional food record phe/protein/calories facts so that you can use later on your cell phone, or you can run reports on your diet records, etc.

I am planning to consolidate the two credential together, hope to see it in the next version. Thanks!

Latest Release 1.5

The latest version 1.5 has been released last night and here are some of the new features:

1. About 3000+ food records based on USDA data are added to the site and can be searched via the mobile device.

2. Food categories filter was added into the search page to better refined one’s search along with keyword.

3. An icon is added for each food on your local low protein food list to indicate whether or not the food data is from USDA, Low Protein Food List book or Personal Recipes.

4. Diet Records manage page now allows Upload function to overwrite a previously uploaded daily diet records on the server side.

Let me know what else you would like to see to improve.

Application Use Case

A few of you asked me for a use case to demonstrate how this app helps me in my life. Here is one.

What I did for myself is that I added the most commonly used 300+ foods my son Vincent eats into my web site and that’s what my application search is currently based on. Everytime we encounter a new food, I just log into www.mypkudiet.com and add the nutrition facts for it so i can use it afterwards. Once I add a food into his diet, three key nutrition facts’ total will be calculated so I can track how much phe, protein and calories in his diet for the day. Any user can do the same thing.

Today, I released the PKUDietBook application to the Android Market so it can be downloaded from any Android based cell phone with internet access right off your device. The default username and password will give you the ability to search my database for low protein foods (phe fact and calorie amount) and to manage diet records on the device. But if you want to upload diet records to the application’s companion web site http://www.mypkudiet.com for record keeping and sharing, you will need to go to the web site and register for a new account.

Currently my database has about the most popular 200+ low protein food records that my son has been eating for his PKU diet. A registered user can login the web site and create  as many as foods from various data source of your own choice. If you like, I can help batch load your low protein food list if you can put them into a spreadsheet format provided. Please feel free to contact me @ tlee@mypkudiet.com if you would like to help.

Search keyword “PKU” on the official Android Market.


The Android based mobile application, PKUDietBook, has not been published on the Android Market yet, while I continue to work on some of the final details. I am planning to get it out on the market before the end of this year to make it easier to install. In the meantime, please feel free to contact me if you are interested in using this application, and I would be more than happy to set you up on both your cell phone and the web site.
