Growing Weary of Superfoods? 4 Plants That Don’t Deserve The Name

superfoods

Do superfoods live up to the hype?

Are Superfoods Overrated?

The term ‘superfood’ is occupying a growing niche in popular vernacular.

The term originally applied to exotic foods that you can’t buy at your neighborhood grocery store that have unique health benefits.  Or at least foods that were supposed to have remarkable health benefits.

Since then it’s been extended to more pedestrian foods as long as they serve some sort of medicinal or health function.   Help lower blood sugar, remove toxins from the body, etc.

If you combine these two definitions a “superfood” is any natural substance that has a real or purported health benefit.

So a superfood has basically become a synonym for health food, but with a little more ambiguity.

It actually seems a little silly to me, but whatever.  If it creates the mood necessary to adopt a wholesome diet, then so be it.  Superfoods it is.

However it’s important not to get carried away.  I’m a firm believer in the healing powers of good nutrition, but people can get misled by their sense of affiliation.

Sometimes the term “superfood” can get slapped onto something merely because it’s unfamiliar and is grown far away, not necessarily because it’s good for you.

Here are four foods in particular that don’t stand up to the hype.

Why are they overrated?

Because their perception is flawed in at least one of the following ways:

  1. There’s little to no scientific evidence they do anything for your body
  2. They might actually be bad for you, especially if taken in the quantities you can buy them at
  3. Their health functions are very similar to other foods which are much less expensive

So think twice before you fork over some hard earned cash for these dressed up pigs.

horsetail

1). Horsetail

Also known as shavegrass, horsetail belongs to the plant genus Equisetum, a pre-historic family of trees that reproduce by spores.

You don’t see it sold on its own very much, but you’ll occasionally see it listed as a part of other mixtures.

It has a reputation as a diuretic and therefore as a remedy for ailments having to do with improper fluid balance: kidney stones, gout, arthritis, etc.

However, there’s not a single scientific study verifying any of these claims. None!  The only thing I could find is one paper that broke down its mineral composition, which suggested it might have a few anti-oxidative and anti-inflammatory properties to it.

That’s pretty darn thin. Practically anything that’s green has to have a few compounds that oxidize the body.

A useful resource for looking into the verifiable benefits of different foods is the  Natural Medicines Comprehensive Database.  It collects the available research on different herbs and foods and decides if there’s enough evidence to declare it useful, useless, or harmful for different conditions.

Well guess what?  Its stance on horsetail is that there’s not enough evidence to suggest it does anything at all.

The only thing we really know for sure about it is that it’s a diuretic.  That’s nice, but parsley’s also a diuretic.  So is coffee.  You can buy a bunch of parsley at the grocery store for $0.99.

himalayan pink salt

himalayan pink salt is just……salt

2). Himalayan Pink Salt

Himalayan pink salt is salt that’s harvested from the Khewra salt mine in Pakistan (pictured below).  It’s one of the oldest mines in the world, and the soil there has a unique mineral composition which gives the salt a pinkish color and   a few additional trace elements not found in the iodized salt you can buy in the store.

When judging the health benefits of himalayan pink salt, there are three crucial considerations to keep in mind:

  1. It’s salt
  2. It’s salt
  3. It’s salt

Table salt is sodium chloride. So is himalayan pink salt. The same salt that we already eat way too much of.  The salt that causes hypertension and high blood pressure.  The salt that increases formation of LDL cholesterol.  The salt that……….you get the idea.

Detractors might say:

But isn’t is unprocessed? Doesn’t that make it better? 

But what about the trace minerals in himalayan pink salt? 

The differences in chemical composition between different salts isn’t that big.  98-99% of all salt is sodium chloride, which the western world has a problem with. So any discussions about the unique health benefits of himalayan pink salt has to do with the remaining 1-2%.

Pakistani chemists have analyzed the chemical composition of the different salts from the khewra salt mines and the following is what they found:

mineral composition of himalayan salt

the mineral composition of himalayan salt

If you don’t like crunching numbers I’ll do the hard work for you:

  • For every kilogram of himalayan pink salt you get 0.82 mg of trace minerals that your body uses.

Extrapolating from those numbers, if you get your daily recommended allowance of salt entirely as himalayan pink salt then you’ll get 1.2 micrograms combined of the different minerals contained in himalayan salt.  That’s literally about one speck of dust.

A pound of himalayan pink salt costs about $10.  You can get a pound of table salt for about $1.

If you want to use himalayan salt as a garnish then that’s fine.  But it hardly qualifies as a superfood.  Here’s another good article explaining this in more detail.

elk antler velvet

Elk antler velvet is interesting, but unverified

3). Elk Antler Velvet

Elk antler velvet began to garner a lot of attention after Rick Rolle wrote about it on the blog of Tim Ferriss.  Elk Antler Velvet is the cartilagenous material found in antlers, and also includes the fuzz that shows up on the outside.

Elk antlers grow very quickly and contain lots of growth hormones and proteins that stimulate testosterone production and a variety of other hormonal changes.

It’s use in the supplement industry has sprang up recently, and it’s very expensive. 1 oz of concentrated elk antler extract costs $150.

Yo, mamma!

Elk antler velvet certainly scores points for novelty, and it probably does have a variety of unique nutrients.

However, nobody’s quite sure what they are yet.

I’m actually all for medicinal experimentation and formal studies aren’t the end all-be all of articulated wisdom on a subject.

In fact I’d be willing to bet that elk antler velvet is in fact a superfood….but right now it’s hard to say.

A search on pubmed for elk antler velvet returns 12 results. By comparison green tea returns 4690.

So as you can see, there’s quite a disparity between it and some of the more documented superfoods out there.

From what I can find there are three studies done on humans with regards to elk antler velvet.  From them here are the three take home points:

  1. That’s not very many
  2. None of them are especially conclusive
  3. None of them found elk antler to have much of an effect on anything.
Let me re-iterate that:  No study has found a positive correlation between elk antler and its purported health benefits in humans.  And there’s hardly any research that’s been done at all on the substance as a whole.
Given its high price and lack of surrounding evidence, I reckon the amateur herbologist is well suited to look elsewhere for his daily dose of superfoods.
Klamath Lake Blue Green Algae

The algae at Klamath Lake Changes Its Color

4). Klamath Lake Blue Green Algae

I’ve written about klamath lake algae before.  It’s a type of blue green algae found in a eutrophic lake in Oregon.  The scientific name of the algae is Aphanizomenon flos-aquae, and it’s actually toxic to the human body wherever its found.  Blue green algae naturally produce compounds called microcystins that cause problems in the liver.  Usually the concentration of microcystins in blue green algae makes it poisonous to humans but for some reason the water in klamath lake makes it edible.

From what I’ve read the most notable aspect of Klamath algae is its unusually high concentration of a type of molecule called  phycocyanin, which is also present in spirulina and chlorella but to a much smaller degree.

Like elk antler velvet there’s very good reason to believe that it does have some remarkable health benefits but little formal studies to validate our intuitions.

The best you can say is that it’s similar to spirulina and chlorella and we both know those two fresh water algaes are extremely nutritious and worthy of the term “superfood.”

Of course, that brings me to my next point.  Even though it’s similar to spirulina, it’s much more expensive.

For example on iherb 130 capsules of spirulina costs $15.   A similar amount of Klamath Lake algae costs $28.

And of course the health benefits of spirulina are well documented, and we don’t have to worry about any of that potential toxicity stuff.

If you’d like to read a particularly damning opinion of Klamath Lake algae and the people who sell it, here’s a good piece.

Not All Superfoods Are Equal

In my opinion Klamath algae and Elk antler are very interesting, but don’t pass a cost/benefit test.  The claims about himalayan salt border on rubbish.

When discussing superfoods it’s important to remember that they don’t need to be exotic in order to be effective.  A bag of kale costs $4.  Cocoa powder is the most powerful antioxidant in your kitchen, and ginger has been used to treat sickness for centuries.

Some of my favorite homemade remedies (like the superfood cough syrup) are made with ingredients that are in most people’s kitchens.

So eat your superfoods, but don’t go broke doing it.

  1. Great post! I shared it on my fb page, http://www.facebook.com/equilibriumhealthcoaching

    I’ve enjoyed the way you express your knowledge and opinions about the “Superfoods!” One issue I have right now is that a lot of our “organic” herbs and supplements are coming from highly toxic areas of the world–and while they may not be intentionally sprayed, they may have taken up the toxins from the water, soil, or air in those regions. For me, I am now really paying attention to where that particular Superfood is harvested–now I would really LOVE your input on this topic… I’ll be waiting for more witty, incisive information!

      Brookwood,

      Thanks for the kind words. I can make this the topic of a future post? It’s a little bit of a complicated issue, especially because it’s hard to generalize across different regions and different plants.

      My take right now (without doing any additional research) is that berries are very sensitive to growing conditions, and cruciferous roots not so much (ginseng, echinacea, astragalus), because they’re typically grown in various places around the world and under harsh growing conditions.

    Thanks for the detailed post! I’ve got a few questions about Himalayan salt because two claims are often made for it which were *not* covered in your post and one correlation makes me wonder if they might be true.

    Marketers often point to the fact that traditional salt uses an anti-caking agent which is not good for those who eat it. They also say that the refining process involves bleaching salt and heating it to incredibly high temperatures, that this can create health problems, and that salt which is harvested and sold in its natural state does not have these issues.

    Additionally, there is the matter of fleur de sel and sel gris, or “Celtic salt,” which is often recommended by doctors over conventional salt. My question is this: If Celtic salt really does have benefits and is not hype, then why is it not possible that unprocessed pink salt might have some of the same advantages?

    Keep in mind that I’m a person who neither sells condiments nor astroturfs for them, nor am I allergic to understanding which foods that are purported to benefit us actually do. Yerba mate is a real example of a food that is marketed as being better for you than coffee, yet it those who drink it are at far greater risk of developing throat cancer than coffee drinkers. If there are real reasons to conclude that all of these kinds of specialty salts are no different than refined sodium chloride, then sobiet. But if that’s so, then why has my doctor recommended “Celtic salt” (his words) along with a low-carb diet?

  4. very helpful.Thanks, from India

  5. hi, do some know some thing about “calcium fluorophosphate”
    using that in state of salt?
    and where to find it?

  6. There have never been any conclusive studies that show that high salt intake has any long term affects on blood pressure and health. In fact, there have been a few studies that show that salt has almost no impact on blood pressure. Our bodies require sodium to survive, and I have personally experienced “water intoxication” due to normal water intake and a low-sodium diet. That condition can be deadly. I think before people post about the common talking points about sodium intake, they should do a bit of research and not just accept what the government agencies suggest about sodium.
