I think there are a lot more interesting superfoods.

Stinging nettles are amazing: 30% protein by dry weight, incredibly dense with vitamins and minerals, stingers contain human-compatible neurotransmitters. Also, the baby plants are most nutritious and can't sting you yet!

"antioxidants" is also on my bullshit list

What? Sure, don't buy the marketing hype but antioxidants ingested via food (as oppposed to pills) is supposed to be beneficial to you. When you say it's "on your bullshit list" do you mean you don't believe in things like free radicals? Or do you mean that you don't think there's antioxidants in abundant supply in said product?

I believe that food can't be reduced to one ingredient. If something contains antioxidants but also a ton of sugar or other stuff you have take that into account too and see if the net effect is positive or negative. You can't just say food with antioxidants is good for you. It's like eating organic chocolate. It's maybe a little better than regular but it's still chocolate with a ton of sugar so net it's not good for you.

Coconut water is repackaged waste byproduct that someone figured out how to make money off of. It's classic marketing.

The sad thing is that all this marketing prevents people from making real improvements. I know people who wanted to switch to better nutrition but then they saw the cost of "superfoods" and organics and gave up. I told them to just eat regular vegetables but it has to be either superfood or nothing. Same with exercise. Either you have to do Crossfit to the point of exhaustion or just stay on your sofa.

You should see what tourists will pay for certified organic wild Maine blueberries. The only difference between them is they come from a field that wasn't sprayed.

They pay three times the price and six times the wholesale price. They are the same berries, harvested the exact same way.

You can double the price again, if you have someone hand pick them instead of raking them. Even better, you can charge them about the same price and let them pick the berries themselves.

> Either you have to do Crossfit to the point of exhaustion or just stay on your sofa This comes up with some regularity in my circle of friends. They've been sold the idea that the value of exercise is only measured in terms of calories burned per minute of activity. Not only is this negating 90% of the benefits for exercise, it's also a useless measure because it's impossible to out-train a bad diet and excess calo…

I agree with most of your points but you can definately out train excess calories, probably not if you have other commitments like a family or a job, but if you hike all day everyday or are on an extended bike tour you are probably actually going to have trouble getting enough calories and can basically eat as much as you can without consuming too much.

There are sound theoretical reasons to think that antioxidant ingestion ought to be good for you and the antioxidants in your body are certainly important. But all the research I've seen on the matter is that ingesting extra antioxidants has the opposite of the effect you'd expect. I'd guess this is some homeostasis related interaction but I don't think anybody actually knows why.

What is the benefit of containing neurotransmitters? I hit up Wikipedia and see they carry signals. I'm not seeing how that is a benefit, however. They appear to carry any signal, not some special signals. Unless one has too few (I'm not sure what might even cause that) then I'm not seeing why that's beneficial.

Saw a documentary about Tour De France riders. They had to force huge plates of spaghetti into themselves every night to the point of throwing up and still lost a ton of weight during the race. It's hard to stay overweight if you are active the whole day.

They seem to be making strangely isolated measurements that have little to do with the claimed benefits of the alleged superfoods. For starters I think most people agree there is no need to replace electrolytes during endurance activities that do not exceed 1 hour, oddly the length of time in this study. I’m not sure anyone claims coconut water hydrates better than water, but certainly it’s going to be more beneficia…

Once you start getting into this type of thinking it's really easy to go down a rabbit hole. I'd love to see the same research, but if you start digging into this subject you will be disappointed in the answers you get. After researching this stuff as a hobby for some time, I've come to the conclusion that this stuff is not well understood and there is still a lot left to explore. As technical people, we sometimes lo…

Agreed. When I discovered the world of healthy living, I started reading and applying a lot of nutrition advice to my life. It was natural that I would come across research defending both sides of the coin for certain foods (eggs, for example), but I felt I generally became healthier and more aware of what I put into my body. However, over time I felt I read enough to come to the conclusion that we don't really know much at all and so I don't really read about nutrition research anymore. I tend to stick to simple principles now like eat more vegetables and as little sugar as possible. Beyond that, it seems too nebulous.

I don't think they can cross the blood brain barrier, but I think I've read that some can get partially metabolized into a precursor, travel across the BBB, and then re-assembled within the brain.

Probably not particularly necessary for healthy individuals, but could reduce the amount of work needed to synthesize your own transmitters (few steps rather than 'from scratch'). Perhaps some individuals with neurotransmitter deficits could see benefit.

As I'm sure you can tell though, I'm not a trained neuroscientist.

Exactly, my path was similar and I follow similar principles- lean meats, lots of vegetables, some fat, little to no sugar or processed carbs.

Seems like a lot of peopl end up settling into something like this.
