For Food :
Carry ready to eat packs, Khakras, Home made pickles,Learn to make one pot dishes(Dal kichdi, Lemon rice and so on) 
For adapting :
Learn some basics of the country’s culture including how to greet someone you meet for the first time.
Learn some words of their native language. If they see that you are making an effort to talk in their language, they will be ready to help you. 
Shop for all the essential clothing based on the seasons there.
Eating and adapting to foreign culture is necessary.
Some easy-to-cook recipes are instant poha/upma mixes, frozen parathas & rotis, and dal & rice (cooker/instant pot).
Carry snacks, fryums, instant mixes and frozen foods are good to go. If you’re planning for a longer stay carry some basic masalas and all.
Choose easy foods like fruits, yogurt, eggs, instant oats, rice, noodles, and frozen veggies. Acclimate by exploring local cuisine gradually, staying hydrated, joining cooking groups, and sticking to familiar spices.
When studying abroad, try new foods, research local cuisine, and explore markets. Pack snacks, stay hydrated, and prioritize food safety. Consider cooking classes or online resources for recommendations. Be open-minded and engage with local culture to enhance your culinary experience.
I literally saw my vegetarian friend turning into no vegetarian , the cultural difference is big , on the name of vegetarian food they literally only gave salad .
Yes!
Taking ready to eat snacks like ready to eat upma or noodles can also help…
In the beginning, it was very problematic since I am a vegetarian but later I got to know all the Georgian vegetarian cuisines like khachapuri, veg kinkali as well as spices like adjika , that made out lives easier…
There were multiple indian grocery stores with all the necessary spices, food items and even utensils to cook …
With time we adapt and it becomes easy to experience that life 
This topic and its comments have some really helpful value for people like me who are about the leave home soon for their study abroad journey!
All the best kritika 
Hope u have a wonderful experience
