Hello Tammy, welcome to our community! That is great that you are about to start pumping. I have been pumping for 30 months and I now have the best control I have ever had. I have very few highs and lows while pumping. A pump can give much more stable control if it is used properly. Be sure you know as much as possible about your pump before training begins. I recommend the book "Pumping Insulin" by John Walsh. I bought mine on amazon.com.
I know a lady from England who is on the ph diet for about a year. She has improved so much and she is taking much less insulin and her A1c's have improved. Good luck with your diet.
I have been Type 1 for 64 years now and I am very healthy. If we have good control then we can have long, healthy lives.
