Thank you very much for your most important question. We are always concerned to make the trip successful without any obstacles. I will inform our Guide about your food concern and he will provide you with gluten-free food entire trek. However, kindly remind him while ordering the food also. We have successfully organized the Everest Base Camp Trek with some other clients who had the same requirements as yours. The primary concern for individuals with coeliac disease is avoiding the consumption of gluten, a protein found in wheat, barley, and rye. In Nepal, the staple food is predominantly rice-based, which is generally safe for those with coeliac disease. However, wheat-based products such as bread, noodles, and pastries are also common.  There are other foods available on the trek for you, Nepali Food "DAL BHAT" is the best option. Generally, the Dalbhat consists of lentils (Dal), rice (Bhat), a vegetable curry (Tarkari), which is a mix of available seasonal vegetables, and green vegetables like spinach (Saag). A small portion of a pickle (Achar) is usually served with it. Dhal Bhat is the most popular food in Nepal due to its various Ingredients, and the important thing is you can eat as much as you like without having to pay extra. There is a most popular provable for the Trek; "Dalbhat Power, 24 Hours". It's important to consult with your healthcare provider or a registered dietitian who specializes in coeliac disease before embarking on the EBC trek. They can provide you with personalized advice, suggest gluten-free alternatives, and ensure you are adequately prepared for the journey. If you could provide a list that you cannot have would be best.
