Bringing food to China

I'm travelling to China soon, and I have to follow a specific nutrition diet, and I'd like to know if I can bring with me the following type of indutrialized food:
1. Almond flour
2. Erythritol (sweetener)
3. Cocoa powder
4. Pink himalayan salt
5. Coconut oil
6. Pita bread
They all have labels and are packed.
Thank you very much for your help!
