A problem with this kind of tasty food here is that you become depended on it, usually having no such luxuries so a more spartan question.
I use a lot of vitamin supplements for B, C, D and Calcium. B, D and Calcium require oil to absorb so they are in green containers like in the picture. C is water-soluble so it is in blue container, good after tiresome touring to get them fast. I use different sized containers such as this large one and this small here but use these ones here for color-coding. You cannot use permanent marker on the aluminium surface because it gets away fast, I used scissors to do the markings. The black one is for emergency, details here.
Then, I use a lot of dry things such as soy powder (protein), muesli(good to have in pocket, just because I like it), salt(essential to get after long riding) and sucker (good to get energy fast). They don't weigh much. Then, I just throw random things I can pick during journey like vegetables and fruits. What about your food during touring? How do you eat during touring? I am interested in a self-sustainable way of living that guarantee necessary intake of important vitamins-calories-and-such-things. I have no idea whether soy powder, for example, is available everywhere so perhaps you must substitute its protein with something else in different locations. So what is your touring food?
