Well, essential nutrients are a bit different thing, but even that doesn’t really help. The issue here is that there is an unstated underlying assumption that everyone needs all the essential nutrients and the more the better.
To give an example, iron is an essential nutrient. Without it you get anemia and eventually die. So, should I consume more of this essential nutrient? In my particular case, the answer happens to be no—I have a bit too much iron in my blood already.
Unsurprisingly, for many essential nutrients you can have too much as well as too little. And yet the conventional wisdom is that the more nutrients the better.
Human biochemistry is very complicated and all the public discourse about the diet can manage is Less calories! More nutrients! Ugh.
(yes, I know, I’m overstating things for dramatic effect :-P)
I agree with you that ‘more nutrients!’ is not sound advice, but again, I never said anything like that, not even implicitly.
Human biochemistry is indeed very complicated. That’s exactly why I responded to ChrisHallquist’s remark about ‘sugar being bad’, because I feel that that is vastly oversimplifying the issues at hand. For instance, simple sugars like fructose exist in fruit, and not necessarily in small amounts either. Yet I don’t think he would argue that you should avoid all fruit.

What do you mean by small amounts? In the context of Taubes claiming that people are drinking soda because they don’t realize it’s unhealthy, this is the amount you’re comparing it with. (For comparison, that’s the amount in fruits.)
I once tried to plan a very simple diet consisting of as few foodstuffs as possible. Calculating the essential nutrient contents I quickly realized that’s not possible and it’s better to eat a little bit of everything to get what you need, unless of course, you take supplements.
Anyone else notice at least three of the soylent guys seem to have this unusual flush on their cheeks? Is this just sheer vitality glowing from them or could there be somethingelse going on? :)
I’ve seen several pictures of Rob and his face seems to be constantly red.
Do you know if their Soylent recipe uses carrots or other pigmented vegetables? It could be an accumulation of the coloring. (This apparently happened to me as an infant with carrots. Made my face red/orangish.)
The early version contains carotenoids found in pigmented vegetables, at least lycopene found in tomatoes, and alpha-carotene found in carrots. It seems you’d get much less carotenoids from Soylent than just eating one tomato and one carrot per day.
He mentions “not very scientific, but the males in my family have always loved tomatoes.” Perhaps that’s the explanation and not Soylent, although you get three times less carotenoids from tomatoes compared to carrots so you’d probably have to eat ridiculous amounts of them to become red. Perhaps they love carrots too.

Early recipe, and practically speaking, I don’t know what the effects of one tomato & carrot a day would be! Rhinehart and the others have been on Soylent for, what, a year now? That’s a long time for stuff to slowly accumulate. Most people don’t eat a single vegetable that routinely. During the summer I eat 1 tomato a day (we grow ours) without glowing, but then I don’t eat any tomatoes during spring/winter, which is disanalogous.
Does anyone actually think that the optimal amount of calories is zero and the optimal amount of nutrients is infinity? I haven’t seen many people taking a dozen multivitamins a day but otherwise fasting, so...
(If what they actually mean is that more people in the First World are eating more calories than optimal than fewer, and vice versa for certain essential nutrients, I’d guess they’re probably right.)
Then again, it’s hard for most people to think quantitatively rather than qualitatively, but that doesn’t seem to be a problem specific to nutrition.

It’s common for people to think that they (or others) should consume less calories and more nutrients. They generally stop thinking before the question of “how much more or less?” comes up.

True that, but that doesn’t seem to be specific to nutrition.
(That said, I am peeved by advice that assumes which way the listener is doing wrong, e.g. “watch less TV and read more books” rather than “don’t watch too much TV and read enough books”.)

I am not arguing against you...
Well, ChristHallquist is reading Taubes and for Taubes insulin is the devil, along with the carbs leading to it :-/

Yes, that’s the idea behind Soylent but I’m rather sceptical of that concept.

Breatharians come close, but I guess the only nutrient they acknowledge is sunlight/vitamin D.
