As enlightened eaters begin to question the healthfulness of highly processed and fast food, many are turning to the Whole30 Diet as a way to cleanse themselves of the junk. Whole30 is being embraced with a frenzy of fad-like enthusiasm (warning bell!), so several close friends have asked for my opinion.
At first glance, this approach seems to be an exciting way to cut the junk and focus on whole foods. After all, the first rule of the Whole30 Diet is the Pollan-esque mantra “Eat real food.” However, if you dig a little deeper into the rules of Whole30, and you’ll find that much of the “real food” as we know it is expressly forbidden on this diet. Don’t believe me? Here is why the Whole30 Diet is a misguided approach to healthy eating.
Whole30 eliminates all grains: Building on the gluten-free fear mongering of other pop-science books (I’m pointing at you, Wheat Belly), Whole30 eliminates all grains, including healthy whole grains, because of their “problematic proteins,” like gluten.
This in itself is a misguided interpretation of science. Indeed, in people with Celiac Disease and some gluten sensitivities, the body perceives gluten as an enemy, and produces an inflammatory immune response. But for the vast majority of the population without gluten disorders, that’s not what happens. In fact, eating whole grains, is associated with decreased inflammation. In a recent clinical trial, researchers found that eating a cup of whole grain barley or brown rice (or a combination of the two) for as little as four weeks can increase the “good” bacteria in your gut that fight inflammation.
A diet without grains but with unlimited red meat is basically just an Atkins diet. There is no reason for this to be disguised as a “whole foods” eating pattern, when entire groups of whole foods are eliminated. Any diet that bans nutritious whole grains like quinoa and millet, but allows you to survive exclusively off of bacon and Larabars, should make you question the legitimacy of its health claims.
Whole30 eliminates all legumes: Another healthy food group, axed from the menu! The creators of Whole30 warn that legumes (like chickpeas, black beans, or lentils) have high levels of phytates, which can block the uptake of certain nutrients by our bodies. While this might sound alarming, what Whole30 enthusiasts fail to understand is that SO many factors affect our uptake of nutrients (how a food is stored, processed, and cooked, what else is eaten with it, etc) and that the reductionist approach of analyzing foods by the milligrams of nutrients that you may or may not be fully absorbing is an entirely fruitless pursuit.
Additionally, these “nutrition experts” (those are sarcastic quotes) fail to understand that ALL plant foods contain varying level of phytates, and that many of the foods promoted by Whole30 (such as kale) have even more phytates than legumes. Phytates are also found in pasture raised and wild meat, based on which plants animals ate during their lifetime. And on top of everything, phytates (natural plant defenses) are not necessarily a bad thing! These bioactive compounds act as antioxidants in the body, and have been linked to anticancer activity, as well as cholesterol lowering effects. (This should not be surprising – we all know that beans are healthy.) The only way to avoid all phytates is to eat highly processed and synthetic foods – which basically defeats the entire philosophy of Whole30.
Whole30 eliminates all dairy. Plant-based diets that eliminate animal products, including dairy, can certainly be extremely healthy. Indeed, T. Colin Campbell (The China Study) and the Harvard School of Public Health bring up excellent points that are leading nutrition researchers to revisit the connection between dairy and bone health (it’s not as straightforward as we once thought).
That being said, fermented dairy products, such as yogurt, and some raw milk cheeses, are great ways to stimulate beneficial gut bacteria. Everyday new research is uncovering the importance of the microbiome. Already, we are finding that a wide variety of healthy gut bacteria are thought to be linked with everything from infections, to obesity, to allergies. Additionally, if dairy is banned in addition to grains and legumes, there really isn’t much left to eat! What kind of healthy diet eliminates half of the food pyramid?
Whole30 eliminates “psychologically unhealthy foods”: The creators of Whole30 claim that smoothies, healthy baked goods, and basically any recipe resembling something that you might actually want to eat is “psychologically unhealthy,” because it is too similar to the standard American diet. Because, you know, Americans became obese from drinking too many kale smoothies and making too many loaves of naturally sweetened, whole grain banana bread (ahem, not!).
Judging by the no-apologies way that the rules are written up (and by the rules themselves), Whole30 seems to be designed to take the pleasure out of eating. This is a terrible idea. The last thing people need is another fad diet that they stick to for 30 days and then drop. I truly believe that healthy eating is not a punishment – if done right, it can be joyful, delicious, and a lifelong habit. But Whole30 is not healthy eating done right. It is restrictive, antagonistic, and completely misguided.
Additionally, while Whole30 gurus may be opposed to “psychologically unhealthy” foods, they seem to have no problem with physiologically unhealthy foods – in other words, an eating pattern guaranteed to make you feel like crap. While adjusting to a higher fiber diet can take some time (the key to avoid intestinal discomfort is to add fiber slowly over time, and drink LOTS of water!), no “healthy” diet should EVER make you feel “hungover” or like you want to “kill all the things,” which the creators of Whole30 brush off as perfectly normal (it’s not!).
Despite these shortcomings, there are some important lessons to be learned from the program:
At the heart of it, the elimination of highly processed foods is what makes the Whole 30 diet seem so appealing. Americans (and increasingly, folks in other nations as well) are hooked on snack foods—packaged ‘Frankenfoods’ formulated from the same handful of highly processed ingredients. In contrast, healthy diets should be based on a wide variety of minimally processed plant foods, like fruits, vegetables, whole grains, nuts, beans, and fish. While Whole30 creators seem to be confused about what a whole foods diet is, their heart seems to be in the right place (maybe).
The Whole30 regimen also asks participants to abstain from added sugars for 30 days. While a few teaspoons a day isn’t going to kill you, most people could definitely use a break from this over consumed food. After all, the World Health Organization recommends that adults cut back to only 6 teaspoons a day. Additionally, Whole30 urges participants to abstain from alcohol. Moderate alcohol consumption–especially red wine–is shown to have numerous health benefits. But judging from the number of drunken people I’ve seen on the T around Saint Patrick’s Day (or on 6th Street, in college), I’m sure there are plenty of folks that could benefit from a month without alcohol. Bottom Line: If you want to purge your diet of everything remotely impure for 30 days, do just that! But don’t exclude wholesome plant foods, like whole grains or beans.
You wouldn’t get open-heart surgery from an auto mechanic, so why would you follow nutrition advice from someone with zero education or training? While one of the Whole30 cofounders might be a “sports nutritionist,” all that’s required for that designation is to pass one test. No nutrition degree (or even nutrition classes), no supervised practice, and no accredited internship required. The startling nutrition deficiencies in this program are all the more reason to seek nutrition advice from a trained nutrition professional, like a registered dietitian.
