In light of the release of Huel V2.0 and some of the backlash against it’s new formulation (e.g. addition of Fluoride, added Sodium (Salt), swapping methylcobalamin for cyanocobalamin, etc.) by the community, I propose the open formulation of a DIY Huel (“Duel”?). I don’t expect this to achieve the same levels of quality nutrition but it can get very close and it certainly won’t compete on price or convenience.
The core ingredients for Huel are simple and are a significant attraction for a lot of users. These can be sourced independently from various places - myprotein.com is a great place to start the hunt.
Oats - http://www.myprotein.com/sports-nutrition/instant-oats/10529296.html (NOT Gluten Free)
Pea Protein (Isolate) - http://www.myprotein.com/sports-nutrition/pea-protein-isolate/10530136.html
Flaxseed (aka. Linseed) - http://www.myprotein.com/sports-nutrition/flax-seed-powder/10529274.html
Brown Rice Protein (Isolate) - http://www.myprotein.com/sports-nutrition/brown-rice-protein/10530779.html
MCT Powder (Isolate, from Coconut source) - http://www.myprotein.com/sports-nutrition/mct-powder/10575138.html (likely not from a Coconut Source; unfortunately not vegan - contains Sodium Caseinate [Milk])
Sunflower Lecithin - http://www.bulkpowders.co.uk/sunflower-seeds.html (whole seeds, not Lecithin)
Aside from the Oats containing Gluten and the MCT Powder containing Milk, everything there is Vegan and Gluten Free. And that is without even looking much beyond a single website. Voilà, the core ingredients of Huel. With a little bit of creative thinking and mathematics (linear programming) we could discern the correct proportions of each to achieve a similar nutritional information profile to Huel.
Vitamin and Mineral Blend - There are many options for this - e.g. http://www.myprotein.com/sports-nutrition/multi-vitamin-powder/10529755.html (this seems to be quite incomplete however). Another option - http://www.myprotein.com/sports-nutrition/alpha-men/10530421.html
Soluble Dietary Fibre (Gum Arabic) - Psyllium Husks are a great alternative and can be found here - http://www.myprotein.com/sports-nutrition/powdered-psyllium-husks/10530061.html. Or they supply other Gums like Xanthan and Guar.
While it would be convenient to get all of these components from one source (e.g. myprotein.com) especially to save on shipping, in an attempt to optimise for various things (price, quality, vitamin/mineral coverage, etc.) I’d expect to have to look around more.
Let me know what you think. There is a thriving DIY Soylent community, so why not this.
Edit: Plenty of flavours to keep everyone happy here - http://www.myprotein.com/sports-nutrition/mp-flavouring/10797025.html
Edit2: Some aspects of the design philosophy for Duel will be minimalism (no needless ingredients - e.g. thickeners) and stoicism (nutrition trumps taste).
