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 give attention to particular person meals is price pursuing within the first place. The very fact is, broader dietary patterns are rather more helpful for predicting well being outcomes than the consumption of anyone meals, regardless of how wholesome it’s.
Nonetheless, superfoods are mega stylish. Google information search tendencies present that there was an enormous spike in searches for superfoods beginning mid-2016, and the variety of internet searches have usually been a lot larger all through the previous ten years than the six years earlier than that.[1] “Tremendous meals” returns greater than a billion Google search outcomes, a lot of that are targeted on the very same questions:
- What’s a superfood?
- What number of superfoods are there?
- How can 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 of this give attention to superfoods; the effectiveness of this give attention to superfoods; and the potential risks of this give attention to superfoods.
And that’s worrying. As a result of though lots of the meals touted as “tremendous” are certainly wholesome, our celebration of their miraculous properties typically goes overboard, and there are damaging unintended effects of those attitudes.
Though lots of the meals touted as ‘tremendous’ are certainly wholesome, our celebration of their miraculous properties typically goes overboard, and there are damaging unintended effects of those attitudes.
For one factor, the recognition of this idea illustrates how advertising and marketing has come to dominate over diet. Is that basically price preserving and inspiring? Do we actually wish to strategy one thing so important as our well being by means of such advertising and marketing gimmicks?
Can we not encourage wholesome conduct one other means?
However possibly that critique appears somewhat summary and idealistic. Listed below are three particular explanation why a give attention to “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 commonly accompanied by little or no textual content. Perhaps a brief paragraph, however typically even much less.
These articles are straightforward to learn and simple to beautify with colourful, mouthwatering photographs. Sadly, as a result of they don’t supply the enough house to cowl any meals merchandise in depth, they’re additionally extremely inclined to deceptive info.
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 usually as, “one of many healthiest meals.”[2]
At a look, the declare that eggs are a superfood appears laborious 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 … recognized to guard imaginative and prescient and eye well being … [and] regardless of fears surrounding egg consumption and excessive ldl cholesterol, analysis signifies no measurable enhance in coronary heart illness or diabetes danger from consuming as much as 6–12 eggs per week … extra analysis is required to attract a particular conclusion [emphasis added].
There are a lot of points right here to unpack.
First, with out immediately evaluating eggs to every other meals or mixture of meals, the declare of nutrient richness says little or no. I don’t imply to recommend that eggs aren’t nutrient dense, solely that better context is required. Nutrient density alone says little or no. Many “nutrient-dense” meals even have much less favorable qualities, corresponding to excessive ranges of ldl cholesterol, fats, and animal protein. Shouldn’t that 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 ought to be considered larger high quality than the protein offered by different meals. It says nothing in regards to the historical past of measuring protein “high quality,” which has lengthy been biased towards animal protein with out convincing justification.[3] And the way might it elaborate on these topics? Bear in mind, this is only one merchandise in a listing of 16 superfoods; how a lot textual content can actually be devoted to every merchandise?
Third, and maybe most misleadingly, is the point out of eggs antioxidant content material, which suggests that eggs are uniquely good for eye well being. By no means thoughts that many meals present way more of those antioxidants than eggs, and that neither of the references within the Healthline article point out eggs as particularly good sources of those antioxidants.[4][5]
If it’s potent antioxidants that you just’re after, 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 better portions of those antioxidants than eggs. The next chart consists of solely a few leafy greens—there are a lot of extra containing massive portions of lutein and zeaxanthin—however mess around with the MyFoodData database[6] for even a short time and you may see how eggs stack up.

Fourth and at last, the article addresses one of the vital widespread considerations related to egg consumption—its excessive ldl cholesterol content material—and “debunks” these considerations by offering two “trusted sources,” each of which disclose authors’ prior connections to the animal meals business.[7][8] This isn’t to say these researchers shouldn’t be taken critically, however provided that none of the opposing analysis on the potential damaging results of egg consumption was mentioned in any depth in any way, the Healthline article’s presentation of the analysis hardly comes throughout as balanced or deep sufficient.
Granted, all of those arguments for why eggs ought to be thought-about superfoods might be offered in any article format, they usually typically are. However the format of superfood lists, which emphasize brevity and magnificence over substance and depth, make them particularly inclined.
In different phrases, it’s not that this info wouldn’t exist in any other case, however that the way in which 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 a substantial amount of conflicting proof—kale, as an example, is clearly loads much less controversial as a “well being meals” than eggs—emphasis on superfoods nonetheless has damaging results. Specifically, by specializing in particular person meals, we’re extra inclined to search for “magic bullets” moderately than sweeping change.
And within the case of people who don’t benefit from the commonly-marketed “superfoods,” our outsized emphasis on them may also discourage lasting change. Individuals who don’t like kale shouldn’t really feel pressured to eat it anyway simply because it’s stylish. Bok choy may not prime as many lists of superfoods, however that’s okay.
In different phrases, we should always lean towards the wholesome meals that we get pleasure from most, and revel in their selection, not demand perfectionism primarily based on the recognition of single meals gadgets.
Moreover, most Individuals’ diets require a much more substantial change than the introduction of some meals. Our outsized give attention to these meals doesn’t encourage that substantial change, and would possibly give folks a false sense of safety (i.e., I acquired my every day dose of turmeric and blueberries—lined my bases!)
In fact, if we get pleasure from turmeric and blueberries and wish to combine them within the context of a complete meals, plant-based (WFPB) food plan, then that’s nice. However we ought to be cautious of enthusiastic about 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 troublesome to realize on the typical particular person’s finances. It’s a fable, and it ignores a number of key prices related to meals—particularly the price of illness and the cheapness of wholesome staples (meals like candy potatoes, legumes, entire grains).
As soon as once more, our give attention to superfoods typically makes this situation worse.
That’s as a result of lots of the meals labeled as “tremendous” are fairly costly, and typically troublesome to seek out. That doesn’t imply they aren’t wholesome, however so long as we would like the follow of well being to be extensively accessible to all people, we should always keep away from inserting an excessive amount of emphasis on issues like cordyceps mushrooms, maqui berries, and maca powder.
You would possibly personally resolve to benefit from the distinctive well being advantages of those meals, and that’s honest sufficient. Simply do not forget that the extraordinary results of broad dietary change that comes with a variety of inexpensive meals are rather more spectacular.
On a societal, communal, and even familial stage, the stakes are even larger. It’s a lot more durable to finances for meals like acai berry powder than for meals like purple cabbage. We ought to be encouraging not solely sweeping change of the meals we eat, but additionally sweeping change of how “regular” folks view the price of well being.
Too typically, superfoods encourage the other 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 realize a wholesome, rich and lengthy life, and thus social distinction.”[9] In different phrases, entrepreneurs aren’t solely promoting “well being,” but additionally a sense of superiority, elitism.
Effectively-meaning customers can’t be blamed for that. Who wouldn’t wish to eat the healthiest meals obtainable? Even when solely only for additional 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.
However wait — aren’t there advantages?
You would possibly surprise: if extra persons are consuming kale and goji berries on account of the 1000’s 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 neglect—there are a lot of different methods to encourage the consumption of kale and goji berries, and plenty of of them are freed from the bags listed above. As an example, we might merely share the physique of proof supporting a WFPB food plan, which inspires the consumption of various plant meals with out getting caught up on any particular person meals merchandise. We might additionally higher practice well being professionals in diet. We might advocate for quite a few modifications that will restrict the affect of business over nationwide meals coverage.
These may not be the sexiest, most clickable, or most worthwhile solutions. However is that so unhealthy? We’ve given advertising and marketing and revenue a flip at dominance. We’ve given issues like attractive, clickable superfoods a complete lot of consideration. Perhaps it’s excessive time we thought-about accountable alternate options.
