Hi Hopers,
welcome to the board.
It's difficult... if you do have a protein indication (which usually is only the case if you buy something in a store) you can calculate the phe amount like this:
Amount of protein multiplied with 30 = Phe amount of fruit based nutrition (f. e. smoothies etc.)
Amount of protein multiplied with 40 = Phe amount of vegetable based nutrition (f. e. tomatoe sauce without meat or cheese)
Amount of protein multiplied with 50 = Phe amount of all other nutrition (f. e. cheese, bread, crisps, etc.)
but in restaurants, it's not possible to get those indications of protein. Since you don't go out eating every day, I would stick to normal diet and when you go out, I would eat the vegetarian meals (without nuts, cheese, tofu etc.) without thinking too much about the phe amount.
I love sushi veggi rolls or korean salads... mhhhmmm... and when I stick to my diet and go eating out vegetarian meals once a week, there is no bad influence on my phe levels.
What is your favourite meal?
