Sure. But I'd point out that this observation (that you can hedge your bets) cuts against Soylent as well: while consuming regular food to limit your downside from deficiencies in Soylent should work for overprovisioned substances, you're also limiting your upside since the more regular food you consume the less Soylent you must be consuming.
Rob Rhinehart's food replacement Soylent now has a crowdfunding campaign.
If you're interested in one or more of these benefits, send in some money! There is also a new blog post.
