I am considering taking the Trans-Siberian railway. London to Moscow followed by Moscow to Beijing. I have made many long rail trips in the past so comfort, boredom, etc is not an issue. However, on this route, diet is. I don't expect many, or even any, vegan or vegetarian options on board. So, I need some survival food.

I am not so concerned about the health of the diet. I eat very healthily most of the time. A couple of weeks on a poor diet won't kill me. Anyway, I hope that I will be able to get the occasional piece of fruit. So, what I mainly need is some energy top ups for when I can get no suitable food for an entire day. So, the requirements are:

Energy dense - I don't want to carry too much.

No need for refrigeration.

Can survive rough handling.


Most complete food products are vegan.

"Complete" refers to the nutrients: these products are nutritionally-complete, i.e., they contain all nutrients humans need (based on recommendations from health/nutrition organizations).

They usually come in powder form (you only need to add water), but some also come in bottles (ready to drink) or as bars.

For powder products, the typical preparation takes maybe 3 minutes:

  1. Fill as much powder as you want (= how many calories you want to eat) into a shaker.
  2. Fill the shaker with the recommended amount of water.
  3. Shake it.
  4. Drink it.

Advantages in your case

  • You only need water (and a way to clean the shaker), you are not reliant on anything else.

  • There probably isn’t any other nutritionally adequate food that takes less space / weighs less.

  • The products typically don’t need to get refrigerated, and the minimum shelf life of unopened packs is usually at least several months.

  • Unopened powder packages should survive rough handling (some products have backpackers, among others, as target market).

  • Many ship world-wide, so you could even get a ration shipped to a trusted location on the itinerary.


(attention: some of them also offer vegetarian products in addition to the vegan ones)

  • Ambronite from Finland

  • Bertrand from Germany

    • it’s (as far as I know) the only one that contains only certified organic ingredients, so the B12 (from algae) is not necessarily bio-available
    • it’s (as far as I know) the only drink that contains chewable parts (nuts)
  • Huel from UK

  • Jake from Netherlands

  • Jimmy Joy from Netherlands

    • formerly Joylent
  • Mana from Czech

  • Queal from Netherlands

  • Saturo from Austria

  • Soylent from USA

  • Thanks. I had considered bars but choosing the better ones is a challenge I had not thought of powders; I tend to regard those as weird things that I see in the gym. However, they make sense here. Soylent as a vegan product - ha ha We had that question on whether consenting cannibalism is vegan. – badjohn Apr 15 at 8:24
