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?
Something about Protein sources
touring food
. It usually infers self-sustainability that in turn infer things such as light-weight, durability, --. Notice that some important nutritional things such as protein differ between countries, you cannot expect to get the same NY hod dog from Siberia as locally. The question is very important to prepare people to look for the right stuff, particularly in foreign countries where you may not know the language. I think it can be very valuable to many wanna-be tourers. I know a bit cross-area between food.SO and bicycle.SO but I am asking for your experience.
