Matcha Benefits: Green Tea’s Concentrated Cousin, Fact-Checked

In the final weeks before harvest, tea farmers in Japan drape their fields in shade cloth, starving the plants of sunlight on purpose. The leaves respond by hoarding chlorophyll and an amino acid called L-theanine — which is why matcha glows that improbable green and tastes sweeter and rounder than the grassy tea in a bag.

That much is agriculture, not marketing. The trouble starts afterward, when a centuries-old ceremonial drink gets rebranded as a metabolism-torching, disease-proofing miracle powder. One viral claim insists matcha has 137 times the antioxidants of green tea. Another promises it melts fat while you sip.

The real story is quieter and, honestly, more interesting. Matcha is green tea with the volume turned up — same plant, same compounds, higher concentration. What that concentration does for you, what it can’t do, and where the fine print lives (caffeine, iron, added sugar) is worth ten minutes of your attention.

What is matcha, exactly — and how is it different from regular green tea?

Matcha and ordinary green tea come from the same plant, Camellia sinensis. The differences are in farming and physics. For roughly three to four weeks before harvest, matcha plants are shaded, which slows growth and shifts the leaf’s chemistry: more chlorophyll, more L-theanine, a somewhat different balance of bitter and savory compounds. After harvest, the leaves are steamed, dried, stripped of stems and veins, and stone-ground into a powder fine enough to suspend in water.

That last step matters most for nutrition. With bagged or loose-leaf green tea, you steep the leaves, extract a fraction of their soluble compounds, and throw the rest away. With matcha, there is nothing to throw away — you whisk the entire pulverized leaf into hot water and drink it. Whatever the leaf contains, you consume.

The practical result is concentration. A cup of matcha generally carries more catechins (the antioxidant family green tea is known for), more caffeine, and more L-theanine than a cup brewed from a tea bag, even though the underlying ingredients are identical. It also means matcha concentrates the less welcome contents of the leaf, which we’ll get to.

One framing worth keeping as you read: nearly all of the large human studies behind “green tea benefits” were done on brewed green tea, mostly in Japan and China. Researchers generally assume matcha behaves like a stronger version of the same drink — a reasonable assumption, but an assumption. Matcha-specific trials are still small and few.

What’s actually in a cup of matcha?

Four groups of compounds do most of the work.

• Catechins, especially one called EGCG. These are polyphenols — plant compounds with antioxidant activity in laboratory settings — and they’re the reason green tea attracts so much research. Matcha is one of the densest dietary sources.
• Caffeine. A typical one-teaspoon serving lands somewhere between a cup of brewed green tea and a cup of coffee. More on exact numbers below.
• L-theanine, an amino acid nearly unique to tea, elevated by shade-growing. It’s the compound most often credited with matcha’s “calm focus” reputation.
• Chlorophyll, vitamin K, small amounts of fiber and minerals. Real, but present in gram-scale quantities — a teaspoon of powder is not a salad.

What matcha does not contain is anything mystical. There is no compound in matcha absent from other green tea; the differences are quantitative. That’s worth saying plainly, because matcha marketing often implies a categorical difference where the evidence shows a dial turned up.

It’s also worth saying what “antioxidant” means and doesn’t mean. In a test tube, catechins neutralize unstable molecules called free radicals. In a human body, the story is more complicated: catechins are absorbed incompletely, metabolized quickly, and may work partly through effects on blood vessels, inflammation signaling, and gut bacteria rather than by simple radical-scavenging. High antioxidant content on paper does not automatically translate to measurable health outcomes — that translation is exactly what clinical research tries, imperfectly, to test.

Does matcha really have 137 times the antioxidants of green tea?

This is matcha’s most famous statistic, and it deserves a fact-check. The number traces back to a 2003 laboratory analysis that compared the EGCG content of one matcha sample against one specific brand of low-grade bagged green tea. Against that particular comparison, the ratio was indeed about 137 to 1.

But that’s a bit like declaring espresso 137 times stronger than coffee after testing it against the weakest gas-station brew in the county. When matcha is compared with typical, decently brewed green teas, the realistic advantage in catechin delivery is closer to two or three times per cup — meaningful, but not otherworldly. The gap depends heavily on the matcha’s quality, the brewed tea’s leaf quality, water temperature, and steeping time. A long, hot steep of good loose-leaf sencha closes much of the distance.

Does concentration matter anyway? Possibly. Population studies from Japan have associated higher green tea intake — often three or more cups daily — with lower rates of cardiovascular disease. If those associations reflect the catechins, then a drink that delivers more catechins per cup could plausibly get you to a beneficial intake with fewer cups. That’s a reasonable hypothesis, not a demonstrated fact, because the observational studies were built on brewed tea, and no one has run the decades-long comparison with matcha.

My honest read: matcha is a genuinely rich catechin source, the 137x figure is marketing arithmetic, and “two to three times a good cup of green tea” is both less viral and more true.

Can matcha help your heart?

Heart health is where green tea’s evidence is strongest — with an asterisk the size of a tea field. Large observational studies, including long-running Japanese cohorts following tens of thousands of adults, have found that habitual green tea drinkers tend to have lower rates of cardiovascular disease and stroke than non-drinkers. Harvard’s Nutrition Source summarizes this body of research as suggestive of benefit, particularly for people drinking several cups a day over many years.

Smaller randomized trials add mechanism to the picture. Green tea and its catechins have been shown in some studies to produce modest reductions in LDL cholesterol and small improvements in blood pressure and blood vessel function. “Modest” is the operative word — the effects are real but small, on the order of what you’d expect from one good dietary habit among many, not a substitute for the fundamentals.

The asterisk: observational studies can’t prove cause and effect. Habitual tea drinkers in these cohorts also tended to smoke less, move more, and eat differently, and statistical adjustment never fully untangles a lifestyle. And again, these studies examined brewed green tea; matcha rides along on the assumption that more of the same compounds behaves at least as well.

What I’d tell a reader over coffee — or matcha: if you enjoy it, a daily cup fits comfortably into a heart-conscious eating pattern alongside vegetables, whole grains, and movement. If you don’t enjoy it, nothing in the evidence obligates you to start. The tea is a supporting actor, never the lead.

Calm focus: what L-theanine and caffeine do together

If matcha has a signature benefit, this is it — and it’s the one with the most direct human evidence behind the specific combination matcha delivers.

Caffeine alone sharpens alertness but can also raise heart rate and edge some people toward jitteriness. L-theanine alone appears mildly relaxing without sedation; EEG studies have observed increases in alpha brain-wave activity, a pattern associated with relaxed wakefulness. Put together, a series of small randomized trials — typically a few dozen participants doing attention tasks — found that the caffeine–theanine combination improved accuracy and the ability to switch between tasks, while blunting some of caffeine’s rough edges.

Tea drinkers didn’t need the EEG. The subjective difference between a coffee buzz and a tea lift has been folk knowledge for centuries; the research mostly gives it a plausible mechanism. Because shade-growing boosts L-theanine, matcha delivers more of the amino acid per cup than most other teas, which is why it earns the “calm energy” reputation more legitimately than most wellness claims earn theirs.

Honest caveats: the trials are small, short, and often used isolated compounds at levels that don’t perfectly match a cup of tea. Effects are measured in milliseconds of reaction time and percentage points of accuracy — perceptible, useful for a morning of focused work, but not a cognitive transformation. Anyone promising that matcha will rewire your productivity is selling something. Anyone saying it’s a smoother lift than coffee for many people is on solid ground.

Does matcha boost metabolism or help with weight?

Here the gap between marketing and evidence widens considerably.

The kernel of truth: in laboratory and short-term human studies, green tea catechins combined with caffeine can nudge energy expenditure and fat oxidation upward for a few hours. Some trials of concentrated green tea extracts reported slightly greater weight change than placebo.

The context that deflates the hype: the effects are small — reviews of the research describe differences measured in a very small number of pounds over roughly three months, with many studies finding no meaningful difference at all. Results were inconsistent across populations, and most trials used concentrated extract capsules delivering far more catechins than anyone drinks as tea. The NIH’s Office of Dietary Supplements, reviewing green tea in its analysis of weight-management supplements, characterizes the evidence for a meaningful effect as weak.

There’s also a subtraction game worth naming. When a matcha habit does coincide with weight change in real life, the likelier explanation is often what it replaced. A plain matcha has roughly 5 calories; the blended coffee drink or soda it displaced may have had 300. That swap is genuinely useful — it just isn’t the powder performing metabolic magic.

So: matcha is a fine, nearly calorie-free drink that fits well within healthy eating patterns, and that’s a legitimate compliment. Treating it as an ingestible exercise substitute isn’t supported by the research, and the wellness industry’s insistence otherwise is one of the better arguments for reading past headlines.

What about brain health and memory over the long term?

Two separate questions hide inside this one, and they have different answers.

Short-term attention and focus — covered above — has decent small-trial support via the caffeine and L-theanine combination. Long-term brain health is murkier. Observational studies, again largely from Japan, have found that older adults who drink green tea regularly show lower rates of cognitive decline than those who don’t. A handful of small studies have looked at matcha specifically: one randomized trial in older Japanese adults given daily matcha over several months reported hints of benefit on some cognitive and sleep measures but not others, with results too preliminary to build advice on.

The mechanistic story is plausible enough to keep researchers interested. Catechins cross into the brain in small amounts, show anti-inflammatory and vascular effects in laboratory models, and healthy blood vessels are increasingly understood as central to a healthy aging brain. Plausible mechanisms, however, litter the graveyard of nutrition science — plenty of compounds that looked protective in cells and cohorts failed in rigorous trials.

The fair summary: green tea drinking is associated with better cognitive aging, causation is unproven, and matcha-specific evidence is embryonic. If you’re assembling habits for long-term brain health, the interventions with stronger evidence are unglamorous — managing blood pressure, staying physically active, sleeping adequately, staying socially engaged. A daily matcha can happily sit beside them. It cannot stand in for them, and no honest researcher would tell you otherwise.

Matcha and blood sugar: promising signal or wishful thinking?

Somewhere in between, leaning toward “modest signal.”

Pooled analyses of randomized trials have found that green tea consumption is associated with small reductions in fasting blood glucose — statistically detectable across many studies, but small enough that an individual would be unlikely to notice. Effects on longer-term markers of blood sugar control have been inconsistent, with some reviews finding slight improvement and others none. Observational cohorts add that habitual green tea drinkers tend to develop type 2 diabetes somewhat less often, with all the usual healthy-lifestyle entanglements that make such findings suggestive rather than conclusive.

Mechanistically, catechins may modestly slow carbohydrate digestion and influence how cells respond to insulin, based mostly on laboratory work. Matcha-specific human data barely exist; the assumption is, once more, that concentrated green tea behaves like green tea.

Two practical points matter more than any of the above. First, preparation dominates chemistry: a plain whisked matcha has virtually no sugar, while a sweetened café matcha latte can deliver a candy bar’s worth — turning a drink studied for possible glucose benefits into a glucose challenge. Second, no one managing diabetes or prediabetes should adjust their care plan around tea. If your blood sugar is a medical concern, the drink is a footnote; the conversation belongs with your care team.

Verdict: a small, real-looking effect in the aggregate data, of little standalone consequence, easily erased by two pumps of syrup.

How much caffeine is in matcha — and how much is too much?

Because you consume the whole leaf, matcha carries more caffeine per cup than steeped green tea — typically 40 to 80 milligrams per level teaspoon of powder, depending on the tea’s quality and how much you use. For context, here’s how common drinks compare, using Mayo Clinic’s published estimates alongside typical matcha figures:

Drink	Typical caffeine
Brewed green tea, 8 oz	~30 mg
Matcha, 1 level tsp (~2 g), whisked	~40–80 mg
Brewed black tea, 8 oz	~47 mg
Espresso, 1 oz shot	~64 mg
Brewed coffee, 8 oz	~96 mg

Health authorities generally consider up to 400 milligrams of caffeine per day safe for most healthy adults — roughly five to eight cups of matcha, far more than anyone drinks. Sensitivity varies enormously, though. Some people metabolize caffeine slowly and feel wired or sleepless after amounts others shrug off. Caffeine also lingers: its effects can persist five hours or more, so an afternoon matcha can quietly sabotage sleep in susceptible people.

During pregnancy, the NHS advises keeping total caffeine under 200 milligrams daily from all sources combined — a limit a couple of matchas would approach, especially alongside chocolate or soda. People with certain heart rhythm conditions, anxiety disorders, or acid reflux may also do better with less; that’s a conversation for a clinician who knows your history, not a blog.

The gentle framing that fits the evidence: matcha is a moderate-caffeine drink, milder than coffee, stronger than a green tea bag, and worth counting honestly in your daily total.

The whole-leaf catch: what about lead and contaminants?

Here’s the flip side of matcha’s central advantage. Tea plants absorb whatever their soil offers, including trace heavy metals such as lead. With steeped tea, most of any lead stays locked in the discarded leaves — analyses suggest only a small fraction migrates into the brew. With matcha, there are no discarded leaves. You drink the ground plant, contaminants included.

Before this becomes alarming, proportion: independent testing of matcha products sold in North America has generally found lead levels low enough that a serving or two daily stays within conservative exposure thresholds for adults. This is a reason for informed shopping, not for abandoning the whisk. Still, three sensible precautions follow directly from the whole-leaf logic:

• Buy from established brands that state where their tea is grown and, ideally, publish or reference third-party contaminant testing. Reputable Japanese growing regions have strong agricultural oversight.
• Keep servings reasonable. One to two teaspoons daily is the traditional pattern and the one safety discussions assume. Matcha smoothie-bowl maximalism multiplies leaf intake, and with it, whatever the leaf carries.
• Be more conservative for children and during pregnancy, since developing bodies are more sensitive to lead. Small children have little business drinking a caffeinated beverage anyway.

One more whole-leaf note: tea leaves are rich in vitamin K in laboratory analyses, though a teaspoon of powder contributes a small absolute amount. If you take medication where vitamin K consistency matters, mention your matcha habit to your pharmacist — consistency, not avoidance, is usually the goal.

Is matcha safe for your liver? Untangling tea from extracts

You may have encountered headlines linking green tea to liver injury. The distinction buried in those stories matters enormously, and the NIH’s National Center for Complementary and Integrative Health draws it clearly: the rare reports of liver problems involve concentrated green tea extract supplements — pills delivering catechin loads far beyond what any realistic tea habit provides — and the risk appears higher when such extracts are taken on an empty stomach.

Drinking green tea or matcha as a beverage, in ordinary amounts, has not shown this pattern. Population studies of habitual tea drinkers, including heavy drinkers in Japan consuming several cups daily for decades, do not reveal a signal of liver harm; if anything, some observational data trend the other direction, though that’s far from proven benefit.

Why the difference? Dose and delivery. A cup of matcha delivers its catechins gradually, diluted in water, usually with food nearby. An extract capsule can deliver several cups’ worth in one concentrated pulse. Compounds that are benign as a beverage can behave differently as a megadose — a recurring lesson across nutrition science, from beta-carotene to botanicals.

The practical takeaways write themselves. Drinking matcha in normal amounts is not a recognized liver concern for healthy adults. Green tea extract supplements are a different product with a different risk profile, and anyone considering them — especially anyone with existing liver disease or unexplained symptoms like persistent fatigue, dark urine, or yellowing skin or eyes — should involve a clinician first, not after. Supplements also aren’t reviewed for effectiveness before sale the way medicines are, which is reason enough for caution.

Ceremonial vs. culinary grade: does it matter for your health?

Walk down a well-stocked tea aisle and you’ll meet a price ladder: culinary matcha at one end, “ceremonial grade” at several times the cost. What does the premium buy, health-wise?

Mostly flavor and freshness, honestly. “Ceremonial” isn’t a regulated term — there’s no certifying body, in Japan or elsewhere, that audits the label. In practice, higher grades come from the first spring harvest, use younger leaves with stems and veins more carefully removed, and are ground more finely. Those leaves tend to carry more L-theanine and chlorophyll (hence the vivid color and sweeter, less bitter taste) and sometimes somewhat different catechin profiles. Later-harvest culinary grades are coarser, more bitter, and cheaper — which is fine, since they’re destined for lattes and baking, where subtlety goes to die anyway.

From a health standpoint, the differences are marginal. Both grades deliver catechins, caffeine, and theanine; no study has shown that ceremonial-grade drinkers fare better than culinary-grade drinkers, and none is likely to. The sensible split:

• Drinking it straight, whisked with water? A quality ceremonial or premium grade is worth it — for taste, which is what determines whether the habit survives past week two.
• Blending with milk, sweetener, or batter? Culinary grade is the rational choice.

Two markers of quality matter more than the label: vivid green color (dull, khaki powder is old or oxidized) and a harvest or packaging date. Matcha degrades faster than leaf tea once ground; store it sealed, cool, and away from light, and use it within a couple of months of opening.

The matcha latte problem: how sugar quietly rewrites the story

A plain cup of matcha — powder, hot water, whisk — contains roughly 5 calories and no sugar. That is the drink the research conversation is about.

The drink most Americans actually order is something else. A medium sweetened matcha latte at a typical café runs 200 to 300 calories and can carry 20 to 30 grams or more of added sugar, depending on the shop, the size, and the milk. For scale, the American Heart Association suggests limiting added sugar to about 25 grams a day for women and 36 for men. One green drink can spend most or all of that budget before breakfast — while wearing wellness branding.

This isn’t a scold; it’s arithmetic. Whatever modest benefits catechins may offer for heart health or blood sugar operate at the margins, in single-digit percentages. Twenty-five grams of daily added sugar operates at a much larger scale in the opposite direction. The powder cannot out-argue the syrup.

If the latte is the only way you enjoy matcha, salvage it rather than abandon it:

• Ask for half the standard sweetener, or none, and let the milk’s natural sweetness carry it — matcha’s savory depth pairs surprisingly well with plain milk of any kind.
• Make it at home, where a teaspoon of powder, warm milk, and thirty seconds of whisking cost pennies and put the sugar dial in your hands.
• Watch bottled matcha drinks and matcha desserts, where “matcha” often functions as a green food coloring with a health halo.

The drink earns its reputation plain. Dressed in syrup, it’s dessert — enjoyable, occasionally, and honestly labeled as such.

When should you talk to a doctor about your matcha habit?

For most healthy adults, a daily cup or two of matcha requires no medical sign-off. A handful of situations deserve a real conversation, though — with a physician or pharmacist, not a search bar.

• You’re pregnant, planning pregnancy, or breastfeeding. Caffeine limits in pregnancy are lower (under 200 milligrams daily per NHS guidance), and matcha counts toward the total alongside coffee, soda, and chocolate.
• You take medications regularly. Tea compounds and caffeine can interact with certain medicines, including some that affect blood clotting, heart rhythm, or anxiety. A pharmacist can review your specific list in minutes.
• You have low iron or have been told you’re anemic. Tea polyphenols can reduce absorption of nonheme iron — the kind in plants and supplements — when consumed with meals. Timing matcha between meals usually solves this, but persistent fatigue, pallor, or breathlessness warrants testing, not tea rescheduling.
• Caffeine seems to disagree with you. Racing heartbeat, worsening anxiety, tremor, reflux, or stubborn insomnia are signals to cut back and, if symptoms persist after cutting back, to get evaluated — caffeine sometimes unmasks issues rather than causing them.
• You’re considering green tea extract supplements, especially with any history of liver disease. And seek prompt medical care for possible liver warning signs: yellowing skin or eyes, dark urine, pale stools, or persistent nausea and abdominal pain.

None of this makes matcha risky for the general population. It makes it a real substance with real physiology — which is precisely why it’s interesting, and precisely why edge cases deserve professional eyes.

The bottom line: a good habit, honestly sized

Strip away the neon marketing and matcha holds up better than most wellness darlings. It is genuinely concentrated green tea — two to three times the catechins of a typical brewed cup, not 137 — with a caffeine-plus-theanine profile that small trials credibly link to smooth, focused alertness. It slots into eating patterns that observational research associates with better heart and metabolic health, and drunk plain, it costs almost nothing nutritionally to enjoy.

What it isn’t: a fat burner, a detox agent, a disease shield, or a substitute for sleep, movement, and vegetables. The strongest evidence behind “green tea benefits” comes from decades of people drinking brewed tea, and matcha inherits that evidence by reasonable inference rather than direct proof. Where matcha-specific studies exist, they’re small and early. That’s not a knock — it’s just where the science stands, and readers deserve the map as it is, not as marketers redraw it.

If you already love the ritual — the sift of powder, the bamboo whisk, the thirty seconds of forced attention before the day begins — the evidence gives you every reason to continue and none to stop. If you’re matcha-curious, start with a quality powder, drink it plain or lightly dressed, keep it to a teaspoon or two daily, count the caffeine honestly, and buy from producers who test what they sell.

And if you never acquire the taste? You’ve lost a pleasant habit, not a health necessity. The tea is a fine supporting player in a healthy life. The lead role was never available.

Frequently asked questions

Is matcha healthier than regular green tea?

It’s more concentrated, not categorically healthier. Because you drink the whole powdered leaf, matcha delivers roughly two to three times the catechins of a typical brewed cup, plus more caffeine and L-theanine. But the large studies linking green tea to heart and metabolic health were done on brewed tea, so matcha inherits that evidence by inference. If you drink several cups of good green tea daily, you may reach similar intakes either way.

How much matcha per day is safe?

One to two teaspoons daily is a sensible ceiling for most healthy adults. That keeps caffeine well under the 400-milligram daily level health authorities consider safe for most adults, and keeps whole-leaf intake — including any trace contaminants — modest. During pregnancy, total caffeine should stay under 200 milligrams from all sources, which a couple of matchas would approach. People sensitive to caffeine should scale to their own tolerance.

Does matcha cause jitters like coffee?

Usually less, for two reasons. A serving of matcha typically contains 40 to 80 milligrams of caffeine, below the ~96 milligrams in an 8-ounce brewed coffee. And matcha supplies L-theanine, an amino acid that small randomized trials suggest smooths caffeine’s edge, supporting alert focus with less of the wired feeling. Individual sensitivity still varies widely, and multiple servings or a late-afternoon cup can absolutely disrupt sleep in susceptible people.

Can I drink matcha while pregnant?

In moderation, generally yes — but count the caffeine. The NHS advises keeping total caffeine under 200 milligrams daily during pregnancy, from all sources combined. One matcha typically uses 40 to 80 milligrams of that budget, so a single daily cup usually fits, while two plus coffee or chocolate may not. Because matcha involves consuming the whole leaf, choosing a reputable, tested brand is extra sensible. Confirm specifics with your prenatal care team.

Does matcha detox your body?

No. ‘Detox’ claims have no scientific basis for matcha or any food — your liver and kidneys handle detoxification continuously, and no beverage accelerates them. Matcha does contain catechins with antioxidant activity in laboratory settings, which is a different and much more modest claim. Enjoy matcha as a low-calorie drink with plausible small benefits; skip any product marketed as a cleanse, flush, or detox, since that language reliably signals marketing over evidence.

Will matcha help me lose weight?

Not meaningfully on its own. Trials of green tea catechins with caffeine show effects on weight that are small, inconsistent, and mostly derived from concentrated extract studies rather than tea drinking; the NIH characterizes this evidence as weak. Where matcha genuinely helps is substitution — a plain cup has about 5 calories, so swapping it for a 300-calorie sweetened drink is a real improvement. A sugary matcha latte, of course, cancels that math.

Is matcha good before a workout?

It’s a reasonable choice. Caffeine is one of the best-documented performance aids for endurance and perceived effort, and matcha’s 40 to 80 milligrams per serving sits in a useful range for many people, with L-theanine potentially softening pre-exercise jitters. Evidence for matcha specifically enhancing fat burning during exercise is thin and preliminary. Have it 30 to 60 minutes beforehand, and skip late-day workouts’ matcha if caffeine disturbs your sleep.

Does matcha block iron absorption?

It can reduce absorption of nonheme iron — the type in plants, eggs, and supplements — when drunk with meals, because tea polyphenols bind iron in the gut. For most people eating varied diets, this is inconsequential. If you have low iron, are anemic, or rely on plant sources, drink matcha an hour or more away from iron-rich meals or supplements. Pairing meals with vitamin C-rich foods also improves nonheme iron uptake.

Is ceremonial-grade matcha healthier than culinary grade?

Not in any demonstrated way. ‘Ceremonial’ is an unregulated marketing term, not a certified standard. Higher grades come from earlier harvests and younger leaves, offering more L-theanine, brighter color, and better flavor — worthwhile if you drink matcha plain, since taste sustains habits. Both grades deliver catechins and caffeine. For lattes and baking, culinary grade is the sensible buy. Freshness and reputable sourcing matter more for quality and safety than the grade label.

Does matcha prevent cancer?

No food is proven to prevent cancer, matcha included. Laboratory studies show green tea catechins affecting cancer-related pathways in cells, and some population studies associate tea drinking with lower rates of certain cancers — but human trial evidence is inconsistent, and the NIH notes green tea has not been shown to prevent cancer in people. Matcha can be part of the plant-forward eating pattern broadly linked to lower cancer risk; it isn’t protection in a cup.
