Why Are People Suddenly Eating Handfuls of Spinach Straight From the Fridge?

TikTok is full of microtrends, especially when it comes to food. Eating a whole cucumber, making protein Diet Coke; remember the baked feta pasta? The list is endless and frankly, can be a bit silly. The latest: Creators shoving a whole handful of spinach into their mouths, citing a “max nutritional benefit boost” by doing so. 

Searching for videos about eating a handful of spinach yields hundreds of people looking vaguely uncomfortable while trying to chew and swallow, well, a whole handful of raw, unseasoned spinach. Of course, I have questions. Is this the cinnamon challenge but with vegetables? Do you hate joy? And, the most important, is this *actually* the best way to get nutritional benefits from spinach?

What is this trend, exactly?

Cropping up in feeds in early February, the TikTok videos hinge on two key factors: The spinach has to be raw, and you have to eat it first thing in the morning. One handful seems to do the trick for most, and it appears that nothing else is consumed alongside the spinach. Just a whole bunch of raw spinach. That’s it. That’s the tweet. 

Surely, it would be easier to incorporate it into the smoothie you’re already planning to have, or the omelet you just made, but here we are. 

Why are people doing this?

According to these videos, besides kicking off your day with multiple vitamins, iron, and potassium, some claim it can also “curb carb and sugar cravings” while others assert that doing this every morning helps “train your tastebuds for the day.”

For me, this feels like it’s veering into the 90s and early aughts culture of “no pain no gain,” a mindset that had us doing things like scrubbing our faces with apricot shells every night, and only eating cabbage soup for every meal. 

Not to say those things aren’t great in moderation (gentle exfoliation is wonderful for the skin, and cabbage is a great, nutritionally dense vegetable), but banking your health on one, singular thing isn’t a great road to success. “I think that spinach is obviously a very nutritious food, but it doesn’t contain the full spectrum of vitamins and minerals that one needs daily,” says Christina Manian, RDN, a sustainable food systems professional. “In terms of claims that doing this first thing in the morning hacks your body’s cravings for the rest of the day, I’m not sure whether that’s true.”

So, what’s the actual science behind this trend?

Realistically, there’s just not a lot of science that backs up these claims of tastebud training and curbed hunger. Research done by the University of Buffalo on bitter foods showed that when feeding bitter foods (like leafy greens) to rats, a protein-based salivary compound that was activated when eating something bitter could be trained to increase over time. 

Basically, the press release stated that when that protein was activated, “the bitter tastes like water.” So, the rats could eat more of the bitter foods without minding the taste. It is important to note that studies done in mice and rats don’t translate well to human consequences, as our physiological differences, like hormonal makeup and immune systems, vary too much from these lab mice/rat studies to be able to draw any definite conclusions. In fact, human-based studies show that denying food cravings can actually lead to increased appetites, and even bingeing behaviors. 

However, it’s not all bad news. There is a lot of info that shows food sequencing—starting each meal by eating vegetables, then protein, then everything else—*does* indeed help with hunger cues, satiety, and better blood sugar control. “I often enjoy spinach in the morning (usually cooked with tofu or eggs and whole grain toast) but don’t feel called to eat it raw as the very first thing I put into my body,” says Manian. 

Should you do this trend?

There’s truly no harm (except maybe a minor choking hazard?) in trying this trend. “Considering how most Americans aren't eating enough veggies, I'll count this as a win,” says Lauren Manaker, RDN, a women’s nutrition expert and consultant. “They are still getting fiber and plant compounds when they eat it by the handful.”

If you’re like me, and seeing a new internet trend makes you feel like the oldest, crankiest person on planet earth, take solace in knowing that dietitians believe adding spinach to any part of your daily meal plan is a total win. “Overall, eating raw spinach is an excellent practice, as is eating cooked spinach,” says Manian. “I think if [people] are doing this any time of the day, that’s fantastic, and if they feel inclined to eat spinach in the morning, then that's also wonderful.”
