Superfoods are supposed to supply profound dietary advantages, and they’re marketed as such.
The issue is that it’s not at all times clear whether or not the label is deserved as a result of there’s no accepted customary for what makes one meals “tremendous” and one other merely wholesome.
Furthermore, it’s unclear whether or not this concentrate on particular person meals is price pursuing within the first place. The very fact is, broader dietary patterns are way more helpful for predicting well being outcomes than the consumption of anybody meals, regardless of how wholesome it’s.
Nonetheless, superfoods are mega-trendy. Google information search developments present a large spike in searches for superfoods beginning mid-2016; the variety of net searches has typically been a lot increased all through the previous ten years than the six years earlier than that.  “Superfoods” returns a whole lot of hundreds of thousands of Google search outcomes, a lot of that are centered on the very same questions:
- What’s a superfood?
- What number of superfoods are there?
- How will we receive superfoods?
- That are the most effective superfoods for x sickness (e.g., diabetes), or y life situation (e.g., expectant moms)?
A lot rarer are outcomes questioning the premise, effectiveness, and potential risks of this concentrate on superfoods. And that’s worrying. As a result of despite the fact that lots of the meals touted as “tremendous” are wholesome, our celebration of their miraculous properties won’t be. In reality, I consider the concentrate on these meals usually goes overboard, and I fear these attitudes have damaging repercussions.
The recognition of this idea illustrates how advertising has come to dominate over diet. Is that price preserving and inspiring? Will we want to method one thing as essential as our well being via advertising gimmicks? Can we not encourage wholesome habits in different methods?
However possibly that critique appears just a little summary and idealistic. Listed below are three particular explanation why a concentrate on “superfoods” is harmful.
1. It creates countless alternatives to mislead the general public in regards to the healthfulness of sure meals
Most printed articles about superfoods are formatted as lists of superfoods. In these, every merchandise is usually accompanied by little or no textual content. Perhaps a brief paragraph, usually even much less. These articles are simple to learn and beautify with colourful, mouthwatering photographs. Sadly, they don’t provide satisfactory area to cowl any meals merchandise in depth, which means they’re additionally extra prone to deceptive data.
Let’s take a look at an instance. A pair years in the past, a Healthline article listed eggs as a superfood and described them extra typically as, “one of many healthiest meals.”
At a look, the declare that eggs are a superfood appears onerous to dispute. Right here’s the case they make:
Complete eggs are wealthy in many vitamins … [are] loaded with high-quality protein … comprise potent antioxidants … identified to guard imaginative and prescient and eye well being … [and] regardless of fears surrounding egg consumption and excessive ldl cholesterol, analysis signifies no measurable improve in coronary heart illness or diabetes threat from consuming as much as 6–12 eggs per week … extra analysis is required to attract a particular conclusion [emphasis added].
There are lots of points right here to unpack.
First, with out straight evaluating eggs to every other meals or mixture of meals, the declare of nutrient richness is skinny. Better context is required. Many nutrient-dense meals even have unfavorable qualities, resembling excessive ldl cholesterol, fats, and animal protein. Shouldn’t these downsides determine into our calculation of whether or not a meals is tremendous or not?
Second, the declare that eggs are “loaded with high-quality protein” is supplied with even much less context. The article says nothing about how or why the protein of eggs needs to be considered increased high quality than the protein of different meals. It says nothing in regards to the historical past of measuring protein high quality, which has lengthy been biased towards animal protein and not using a convincing justification. And even when the creator wished to, how might they elaborate on these topics? Keep in mind, this is only one merchandise in a listing of 16 superfoods; how a lot textual content can realistically be devoted to every merchandise?
Third, and maybe most misleadingly, is the point out of eggs’ antioxidant content material, which is used to suggest that eggs are uniquely good for eye well being. By no means thoughts that many meals present much more antioxidants than eggs or that neither of the references within the Healthline article mentions eggs as particularly good sources of those antioxidants.
If it’s eye-healthy antioxidants you need, eggs don’t deserve a spot on the desk. Darkish leafy inexperienced greens specifically are nice sources of lutein and zeaxanthin, offering many orders of magnitude extra of those antioxidants than eggs. Even non-leafy inexperienced greens present a lot larger portions of those antioxidants than eggs. The next chart contains solely a pair leafy greens—there are lots of extra containing massive portions of lutein and zeaxanthin—however mess around with the MyFoodData database for even a short time and you’ll see how eggs stack up.

Fourth and at last, the article breezes by one of the frequent considerations related to egg consumption—its excessive ldl cholesterol content material—and “debunks” the priority by offering two “trusted sources,” each of which disclose authors’ connections to the animal meals business. This isn’t to say these researchers shouldn’t be taken significantly, however contemplating that not one of the opposing analysis on the potential damaging results of egg consumption was mentioned in any depth, the Healthline article’s presentation of the analysis hardly comes throughout as balanced or deep sufficient.
Granted, all of those arguments for why eggs needs to be thought-about superfoods may very well be offered in any article format, they usually usually are. However the format of superfood lists, which emphasize brevity and magnificence over substance and depth, make them particularly prone.
In different phrases, it’s not that this data wouldn’t exist in any other case, however that the best way we ship details about superfoods encourages much more manipulation and cherry selecting.
2. It doesn’t do sufficient to impress broad dietary change, and would possibly even encourage complacency by giving customers a false sense of safety
Even within the case of legitimately healthful meals for which there’s not an excessive amount of conflicting proof—kale, for example, is much less controversial as a well being meals than eggs—an emphasis on superfoods would possibly nonetheless have damaging results. Individuals who don’t like kale shouldn’t really feel pressured to eat it simply because it’s fashionable. Bok choy won’t high as many lists of superfoods, however that’s okay—we should always lean towards the wholesome meals we most take pleasure in, and revel in their selection, not bend to the recognition of single meals objects.
Extra importantly, by specializing in particular person meals, we could also be extra inclined to search for “magic bullets” moderately than sweeping change. Most People’ diets require a much more substantial change than the introduction of some meals. Our outsized concentrate on these meals doesn’t encourage that substantial change and would possibly give folks a false sense of safety (i.e., I obtained my each day dose of turmeric and blueberries—coated my bases!) In fact, if we take pleasure in turmeric and blueberries and need to combine them into a complete meals, plant-based (WFPB) weight loss plan, that’s nice. However we needs to be cautious of interested by them as dietary supplements.
3. It contributes to our society’s distorted notion of how a lot it prices to be wholesome
There’s a extensively held false impression that wholesome consuming is tough to attain on the common finances. It’s a fable that ignores a number of prices related to meals—particularly the costliness of illness and the cheapness of wholesome staples (meals like candy potatoes, legumes, and entire grains).
As soon as once more, our concentrate on superfoods would possibly make this situation worse.
That’s as a result of many meals labeled as “tremendous” are costly and tough to seek out. That doesn’t imply they aren’t wholesome, however so long as we wish wholesome residing to be accessible to all people, we should always keep away from inserting an excessive amount of emphasis on unique merchandise like cordyceps mushrooms, maqui berries, and maca powder.
You would possibly personally determine to benefit from the distinctive well being advantages of those meals. Truthful sufficient. Simply do not forget that the extraordinary results of broad dietary change that includes a variety of reasonably priced meals are way more spectacular.
On a societal, communal, and even familial degree, the stakes are even increased. It’s a lot more durable to finances for meals like acai berry powder than for meals like purple cabbage. We needs to be encouraging not solely sweeping change of the meals we eat, but in addition sweeping change of how “regular” folks view the price of well being.
Too usually, superfoods encourage the alternative perspective.
They epitomize a consumer-producer relationship that’s off-limits to most individuals, such that, “their consumption is seen because the expression of the endeavor to attain a wholesome, rich and lengthy life, and thus social distinction.” In different phrases, entrepreneurs are usually not solely promoting “well being,” but in addition a sense of superiority, and elitism.
Properly-meaning customers can’t be blamed for that. Who wouldn’t need to eat the healthiest meals out there? Even when solely only for further safety and peace of thoughts. Nonetheless, these attitudes have secondary results, and they are often damaging to how we view well being, and particularly to less-prosperous customers.
4. It has environmental and social repercussions usually unseen by customers.
In an article printed in Individuals and Nature, researchers discover how surging demand for superfoods can affect the folks and ecosystems the place these meals are produced. By way of a sequence of case research, they hyperlink superfood commodification to:
- the erosion of native meals techniques,
- the damaging unfold of monocropping,
- decreased genetic variety of flowers,
- a boom-or-bust financial cycle that leaves farmers and communities extra susceptible to the whims of distant customers,
- elevated greenhouse fuel emissions,
- the elevated use of agrochemicals, and
- unsustainable land clearing.
For instance, when demand for quinoa peaked round 2006–2013, farmers responded by departing from extra sustainable conventional harvesting practices. “The demand for quinoa was centered on only some of the over 3,000 totally different varieties [. . . prompting] farmers to desert many of those varieties.” And when the price of quinoa plummeted, these economies had been in a a lot worse place than that they had been earlier than. “Based on a examine carried out on Bolivian farmers of quinoa, greater than half mentioned the standard of their soil has worsened.”
And once more, this isn’t to say that quinoa needs to be averted. Neither is the purpose to sentence unwitting, health-seeking customers that gasoline demand. Nonetheless, it illustrates the unintended results that may accompany the mass commodification of wholesome meals.
However wait—aren’t there advantages?
You would possibly surprise: if extra individuals are consuming kale and goji berries due to the hundreds of articles citing kale and goji berries as superfoods, then isn’t that sufficient of a profit to outweigh the considerations listed above?
Perhaps, however let’s not overlook—there are lots of different methods to encourage the consumption of kale and goji berries freed from the bags listed above. As an illustration, we might higher share the physique of proof supporting a WFPB weight loss plan, which inspires the consumption of numerous plant meals with out getting caught up on any particular person meals merchandise. We might nurture and shield the wholesome meals that develop the place we stay. We might higher practice well being professionals in diet. We might advocate for quite a few adjustments to restrict the business’s affect over nationwide meals coverage.
These won’t be the sexiest, most clickable, or most worthwhile strategies. In some ways, they’re the alternative. However is that so dangerous? We have now given advertising and revenue a flip; for many years, we’ve given issues like horny, clickable superfoods a variety of consideration. How has it helped our well being?
Perhaps it’s time we thought-about options?
