I Drink the Same Smoothie Every Morning. Here's What's In It.

Every morning I make the same smoothie, and it only takes about ten minutes to make. I started doing this because I wanted to make a habit of loading up on the things that are harder to eat standalone like spinach, flax seeds, turmeric, and Brazil nuts. The smoothie gives me a convenient way to get all of these in every morning.

It is a vehicle for nutrients that would otherwise be hard to get. Over a year’s worth of tweaks has led to this recipe, and I genuinely think this is my best yet. Here’s what’s in it, what each thing does, and how to make it yourself.

The Greens

A big handful of dark greens: spinach, kale, arugula, or whatever’s in the fridge. I rotate them on purpose. Different greens have different nutrient profiles, and rotating keeps me from over-loading on any single one. Kale, for example, is loaded with vitamin K.

The greens are the only ingredient that make people hesitate, but with the berries in the mix you almost cannot taste them. Unless you put in too much arugula, in which case you will get an aftertaste.

If you do not want to pick up fresh greens every week, frozen greens are a fine substitute and keep for a long time. They are also a good backup for the mornings when you have run out of fresh and do not want to break the habit. The smoothie ends up being a little colder, so beware of brainfreeze with this substitute.

There are a couple reasons rotating your greens matters. Spinach is high in oxalates, and oxalates are the primary component of the most common type of kidney stone. A big handful of raw spinach every single morning, forever, is enough to be a concern if you are already prone to calcium oxalate stones. Kale and arugula are much lower in oxalates than spinach, so rotating through them is the easy fix. If you have a history of kidney stones, do not make this a spinach-only smoothie.

A similar story on the kale side: cruciferous greens like kale contain goitrogens, compounds that can interfere with iodine uptake in the thyroid when consumed raw in large quantities. The Brazil nut already provides selenium, which supports thyroid function, but someone with existing hypothyroidism should be cautious about blending a big handful of raw kale every single day. The fix is the same one: rotate. If kale, spinach, and arugula are all in the mix throughout the week, neither the oxalate nor the goitrogen load on any given day is high enough to matter.

The Frozen Section

Mixed frozen berries: strawberries, blueberries, raspberries, blackberries. Frozen, not fresh. Frozen berries are picked ripe and flash-frozen, which actually makes them more antioxidant-rich than the under-ripe “fresh” berries trucked across the country. They are also cheaper, last practically forever in the freezer, and they are what makes this a smoothie instead of a juice.

The Small Stuff That Does Heavy Lifting

This is the part where I’d lose people if I tried to feed it to them on a plate.

One Brazil nut. Brazil nuts are the densest natural source of selenium on the planet. A single nut typically delivers more than the daily value, which supports thyroid function. Two is fine. But selenium is one of the few nutrients you can actually stack to excess over time, so I keep it to one a day.

Chia, hemp, and flax seeds. A spoonful of each. Chia and flax give you plant-based omega-3 (ALA); hemp gives you a surprisingly complete protein.

Turmeric and black pepper. This pairing sounds the weirdest and is actually the most studied. Curcumin, the active compound in turmeric, is famously anti-inflammatory but famously hard for your body to absorb. Piperine, the active compound in black pepper, increases curcumin bioavailability by something like 20x. The number traces back to a single human study from 1998, so take it with a grain of salt (and a grain of pepper), but the directional effect is real.

Wheat germ. A spoonful. It’s the most nutrient-dense part of the wheat kernel, the part that gets discarded in white flour. B vitamins, vitamin E, magnesium, zinc. It is also one of the richest food sources of spermidine, a compound that has been getting attention in longevity research for triggering autophagy, which is your cells’ own cleanup-and-recycle process.

Amla berry powder. Indian gooseberry, an Ayurvedic staple. Extraordinarily high in vitamin C and polyphenols, and one of the most antioxidant-dense foods on the planet by ORAC value. (ORAC stands for Oxygen Radical Absorbance Capacity, a lab measure of how aggressively a food’s antioxidants neutralize free radicals.) I picked it up after reading about it in the context of longevity research and never stopped using it. It can be hard to find in regular grocery stores, so I order it on Amazon.

Dried cranberries, reduced sugar. A small handful. Urinary tract benefits, polyphenols, and a little tartness to balance the smoothie’s sweetness.

A splash of apple cider vinegar. Maybe a teaspoon. The acute effect of ACV is real: it blunts post-meal glucose spikes. The longer-term picture is messier, but meta-analyses in type 2 diabetics show reduced fasting blood glucose and HbA1c over multi-week interventions. Don’t go heavier than a splash, though. ACV is acidic enough to wear down tooth enamel and too much can give the smoothie a real acidic taste.

The Banana

Goes in second-to-last. Adds potassium, but more importantly it’s what makes the whole thing taste sweet. With the banana, the smoothie is also much easier to drink. I break it into thirds before it goes in.

The Soy Milk

The last thing in, and the only liquid. Unsweetened soy milk holds the whole thing together: complete plant protein, no added sugar, and it doesn’t separate or get grainy in the blender the way some plant milks do. Unsweetened almond milk works fine if you prefer it, but you give up most of the protein and a lot of the taste.

A quick word on estrogen, because someone always brings it up. Soy contains phytoestrogens (isoflavones), which sound scary because of the name. They bind weakly and selectively to estrogen receptors in a way that does not meaningfully alter hormone levels in men, and the meta-analyses on this have been pretty consistent for years. The real story on soy milk is more boring and more positive: it has a higher protein-to-calorie ratio than cow’s milk, and it is loaded with polyphenols on top of the protein. Soy milk is also free of the antibiotic and hormone residues that turn up in industrial cow’s milk. It is a strictly better fit than the dairy aisle.

How To Make It

I use a NutriBullet. If you’ve never used one: you load the cup, screw the blade onto the top, then flip the whole thing upside-down to blend. Whatever you put in last ends up closest to the blade, which is the opposite of how you’d load a normal blender. The order matters.

Here’s the order:

1. Greens first. A big handful, packed down. They go on the bottom of the cup, which is the farthest point from the blade.
2. Frozen berries. A generous scoop on top of the greens.
3. Everything small. Cranberries, the Brazil nut, amla powder, chia, hemp, flax, turmeric, black pepper, wheat germ. Just dump it all in. A splash of apple cider vinegar in there too.
4. Banana. Broken into thirds.
5. Unsweetened soy milk last. Fill until it touches the banana. The liquid ends up right next to the blade when you flip it, which is what gets the blending started.

Screw the blade on, flip, blend for about 45 seconds. Stop when the sound smooths out.

One thing that happens occasionally: if the spinach gets too tightly packed at the bottom, the blade can spin an air pocket and not pull everything down. If your smoothie comes out with whole leaves still in it, unscrew the top, add a little more soy milk, and blend again. Problem solved.

Drink it out of the blender cup with the To-Go Lid on top. The whole thing is usually too thick to drink with a straw. That’s the point of the NutriBullet: no transfer step, one thing to wash.

Make It Yours

A smoothie is one of the few things you cannot really mess up. If you skip the amla, fine. If you want it sweeter, more banana. If you want it more savory, less banana. The point is to find a recipe you can make in ten minutes, right after you wake up, and get in the habit of eating foods you would not otherwise eat.

Experiment with other things depending on your goals. Different berries, creatine, plant-based protein powder, whatever you are working toward. Just do your own research on new ingredients before you start dumping them in. Meta-analyses are a great place to look (LLMs help for finding these), since they pool results across studies and are harder to cherry-pick than any single trial.

What It Costs

I make a 32 oz cup, and I estimate each smoothie comes out to about four or five dollars. The biggest line items are the fresh greens and the frozen berries. Everything else is small change per serving, even the amla powder, because a spoonful out of a bag goes a long way. The Brazil nut costs about a dime. The wheat germ costs even less.

Five dollars is roughly what a drink at a coffee shop runs these days, which is a useful frame. You are getting twenty-plus ingredients, several hundred calories of real food, and most of your fiber for the day. I think it is a good deal.

A Note on Organic Produce and Food Quality

I buy organic spinach, organic soy milk, and organic frozen berries. I do not buy organic bananas. And I have my own opinion about turmeric.

Spinach. Spinach has been the single most pesticide-laden vegetable in the U.S. by weight for two years running on the Environmental Working Group’s Dirty Dozen list (which ranks fruits and vegetables with the highest pesticide residues after washing). Three-quarters of conventional spinach samples test positive for permethrin, a neurotoxic insecticide that the EU banned from food crops in 2000. Spinach is also the ingredient I use in the largest volume, so it is the place where the organic premium feels most worth paying.

Soy milk. This is the next strongest case for organic after the greens. Glyphosate (the active ingredient in Roundup) works by blocking an enzyme that plants need to make certain amino acids. “Roundup Ready” soybeans are genetically engineered to have a modified version of that enzyme, so glyphosate does not kill them. This lets farmers spray glyphosate directly on the crop to kill weeds. About 94% of U.S. soybeans are grown this way.

The residue numbers are real. The USDA tested 300 soybean samples in 2010-2011 and found detectable glyphosate in 90% of them, averaging about 2 mg/kg. Studies that have looked at genetically modified versus organic soy side by side find roughly 3 mg/kg of glyphosate in the genetically modified soy and zero in the organic. Whether that level of residue matters for human health is genuinely contested. Humans do not have the enzyme glyphosate targets, which is the industry argument for why it is safe for us. On the other hand, the WHO’s cancer agency classified glyphosate as a probable human carcinogen in 2015, the gut bacteria we depend on do have that enzyme, and the EPA’s “acceptable” tolerance for glyphosate in soybeans was raised 200x in 1999 to accommodate the genetically modified crops. The EPA and EFSA still consider it safe at typical dietary exposures.

A serving of non-organic soy milk contains a small enough amount of glyphosate that, on its own, it is nowhere near the regulatory threshold. The argument for organic is less about any single food and more about the fact that glyphosate is in a lot of things now (oats, wheat, corn, soy), and the cumulative low-dose exposure picture is what people are trying to reduce. I find that reasonable. My Kroger carries Silk unsweetened organic soy milk, and my Walmart does not, which is why I switched stores.

Berries. Strawberries, blackberries, and blueberries are all on the Dirty Dozen too. The organic frozen mix runs about 30 cents per ounce versus 22 cents for the conventional, which is a real but not unreasonable premium.

Bananas. Bananas are on the Clean Fifteen, the lowest-residue list. The peel does a lot of work. Not worth the premium in my opinion.

Turmeric. Lead is the concern with turmeric. It comes from soil contamination and intentional adulteration in lower-quality supply chains by using lead chromate as a coloring agent. Organic certification does not test for heavy metals, so it does not consistently solve this. The good news from the same Consumer Reports investigation: McCormick, Simply Organic, Great Value (Walmart), Spice Islands, and Morton & Bassett all landed in the “no concern” or “some concern” categories for turmeric. A brand called La Flor was rated “high concern.”

A broader rule: if you are buying turmeric at a regular grocery store from a major brand, you are probably fine. If you are buying off Amazon or from a brand you have never heard of, be more careful. A 2021 industry test of 23 turmeric supplements from Amazon found heavy metal levels averaging more than five times higher than a control sample, with the worst offenders more than 20x California’s lead limits.

Everything else. The Brazil nut, the seeds, the wheat germ, the cranberries, the amla, the ACV: the residue concern is low enough or the per-serving amount is small enough that I do not bother with organic.

The pattern that makes sense to me:

• For produce, organic is worth paying for where the residue is highest and the volume is largest. For me it is spinach, soy, and berries.
• For turmeric, the organic label is doing different work and is not the signal you want. The signal you want is a brand that has been independently tested for heavy metals.
• For everything else, going organic is more of a luxury with diminishing returns.

A Word on Fiber (and How to Start)

There is a lot of fiber in this thing. Greens, berries, chia, flax, hemp, wheat germ, cranberries.

Fiber is excellent for you in ways that go beyond keeping you regular. The bacteria in your gut ferment it into short-chain fatty acids like butyrate, which the cells lining your colon use as their primary fuel and which seem to play a role in keeping inflammation down. A high-fiber diet is one of the more consistent findings in the colorectal cancer literature: the more fiber you eat, the lower your risk, with most of the benefit showing up at the high end of intake. Most people in the U.S. eat about half the recommended amount. This smoothie alone gets you a long way there.

A word of warning if your current diet is low in fiber. Going from a typical American intake to this smoothie on day one may cause severe bloating, gas, and cramping. The sudden influx of fiber and prebiotic material may be more than your gut microbiome is ready for, and your body may need a few weeks to adapt. The fix is to start with smaller portions, maybe half the recipe, and work up over two to three weeks. Your gut will adjust.

Drinking it slowly is also a good idea regardless of where you are starting from. The smoothie has a real amount of sugar in it: a whole banana, a scoop of mixed berries, and a handful of dried cranberries adds up. The fiber from the seeds and greens slows absorption, but blending breaks down some of the fiber structure that would normally slow things down even more if you ate the fruits whole. For an active person this is a non-issue. For someone with insulin resistance or type 2 diabetes, drinking the whole thing in five minutes could spike blood sugar in a way you do not want. Stretching the smoothie over twenty or thirty minutes flattens the curve considerably. Personally, I take sips of the smoothie while I pack my lunch in the morning.

One last thing to plan around: you are probably going to need to poop about an hour later. Fortunately, it will be easy.

One Last Thing

A challenge: copy this whole blog post into your LLM of choice (ChatGPT, Grok, Claude, Gemini, whichever you trust) and ask it to rate the healthiness of this smoothie on a scale of 1 to 10, where 10 is the healthiest.
