Caffeine: Cognitive Enhancer Or Brain-Wrecker?

The Two Sides Of Caffeine
We asked you for your health-related opinions on caffeine itself, not necessarily the coffee, tea, energy drinks, etc that might contain it.
We have, by the way previously written about the health effects of coffee and tea specifically:
As for our question about caffeine itself, though, we got the above-depicted, below-described, set of results:
- About 59% said “caffeine is a safe stimulant and cognitive enhancer”
- About 31% said “caffeine is a moderately safe recreational drug”
- About 8% said “caffeine’s addictive properties make it de facto bad”
- One (1) person said “caffeine will leave you a trembling exhausted wreck”
But what does the science say?
Caffeine is addictive: True or False?
True, though one will find occasional academics quibbling the definition. Most of the studies into the mechanisms of caffeine addiction have been conducted on rats, but human studies exist too and caffeine is generally considered addictive for humans, for example:
See also:
Notwithstanding its addictive status, caffeine is otherwise safe: True or False?
True-ish, for most people. Some people with heart conditions or a hypersensitivity to caffeine may find it is not safe for them at all, and for the rest of us, the dose makes the poison. For example:
❝Can too much caffeine kill you? Although quite rare, caffeine can be fatal in cases of overdose; such circumstances are generally not applicable to healthy individuals who typically consume caffeine via beverages such as tea or coffee.❞
this paper, by the way, also includes a good example of academics quibbling the definition of addiction!
Caffeine is a cognitive enhancer: True or False?
True, but only in the case of occasional use. If you are using it all the time, your physiology will normalize it and you will require caffeine in order to function at your normal level. To attain higher than that, once addicted to caffeine, would now require something else.

Caffeine will leave you a trembling exhausted wreck: True or False?
True or False depending on usage:
- The famously moderate 3–5 cups per day will not, for most people, cause any such problems.
- Using/abusing it to make up for lost sleep (or some other source of fatigue, such as physical exhaustion from exertion), however, is much more likely to run into problems.
In the latter case, caffeine really is the “payday loan” of energy! It’ll give you an adrenal boost now (in return, you must suffer the adrenal dumping later, along with lost energy expended in the adrenaline surge), and also, the tiredness that you thought was gone, was just caffeine’s adenosine-blocking activities temporarily preventing you from being able to perceive the tiredness. So you’ll have to pay that back later, with interest, because of the extra time/exertion too.
Want to make caffeine a little more gentle on your system?
Taking l-theanine alongside caffeine can ameliorate some of caffeine’s less wonderful effects—and as a bonus, l-theanine has some nifty benefits of its own, too:
Enjoy!

DVT Risk Management Beyond The Socks
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
It’s Q&A Day at 10almonds!
Have a question or a request? We love to hear from you!
In cases where we’ve already covered something, we might link to what we wrote before, but will always be happy to revisit any of our topics again in the future too—there’s always more to say!
As ever: if the question/request can be answered briefly, we’ll do it here in our Q&A Thursday edition. If not, we’ll make a main feature of it shortly afterwards!
So, no question/request too big or small
❝I know I am at higher risk of DVT after having hip surgery, any advice beside compression stockings?❞
First of all, a swift and easy recovery to you!
Surgery indeed increases the risk of deep vein thrombosis (henceforth: DVT), and hip or knee surgery especially so, for obvious reasons.
There are other risk factors you can’t control, like genetics (family history of DVT as an indicator) and age, but there are some that you can, including:
- smoking (so, ideally don’t; do speak to your doctor before quitting though, in case withdrawal might be temporarily worse for you than smoking)
- obesity (so, losing weight is good if overweight, but if this is going to happen, it’ll mostly happen in the kitchen not the gym, which may be a relief as you’re probably not the very most up for exercise at present)
- See also: Lose Weight, But Healthily
- sedentariness (so, while you’re probably not running marathons right now, please do try to keep moving, even if only gently)
Beyond that, yes compression socks, but also frequent gentle massage can help a lot to avoid clots forming.
Also, no surprises, a healthy diet will help, especially one that’s good for general heart health. Check out for example the Mediterranean DASH diet:
Four Ways To Upgrade The Mediterranean Diet
Also, obviously, speak with your doctor/pharmacist if you haven’t already about possible medications, including checking whether any of your current medications increase the risk and could be swapped for something that doesn’t.
Take care!

South Indian-Style Chickpea & Mango Salad
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
We have a double-dose of chickpeas today, but with all the other ingredients, this dish is anything but boring. Fun fact about chickpeas though: they’re rich in sitosterol, a plant sterol that, true to its name, sits on cholesterol absorption sites, reducing the amount of dietary cholesterol absorbed. If you are vegan, this will make no difference to you because your diet does not contain cholesterol, but for everyone else, this is a nice extra bonus!
You will need
- 1 can white chickpeas, drained and rinsed
- 1 can black chickpeas (kala chana), drained and rinsed
- 9 oz fresh mango, diced (or canned is fine if that’s what’s available)
- 1½ oz ginger, peeled and grated
- 2 green chilis, finely chopped (adjust per heat preferences)
- 2 tbsp desiccated coconut (or 3 oz grated coconut, if you have it fresh)
- 8 curry leaves (dried is fine if that’s what’s available)
- 1 tsp mustard seeds
- 1 tsp cumin seeds
- 1 tsp black pepper, coarse ground
- ½ tsp MSG or 1 tsp low-sodium salt
- Juice of 1 lime
- Extra virgin olive oil
Method
(we suggest you read everything at least once before doing anything)
1) Heat some oil in a skillet over a medium heat. When it’s hot but not smoking, add the ginger, chilis, curry leaves, mustard seeds, and cumin seeds, stirring well to combine, keep going until the mustard seeds start popping.
2) Add the chickpeas (both kinds), as well as the black pepper and the MSG/salt. Once they’re warm through, take it off the heat.
3) Add the mango, coconut, and lime juice, mixing thoroughly.
4) Serve warm, at room temperature, or cold:
Enjoy!

Needle Pain Is a Big Problem for Kids. One California Doctor Has a Plan.
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Almost all new parents go through it: the distress of hearing their child scream at the doctor’s office. They endure the emotional torture of having to hold their child down as the clinician sticks them with one vaccine after another.
“The first shots he got, I probably cried more than he did,” said Remy Anthes, who was pushing her 6-month-old son, Dorian, back and forth in his stroller in Oakland, California.
“The look in her eyes, it’s hard to take,” said Jill Lovitt, recalling how her infant daughter Jenna reacted to some recent vaccines. “Like, ‘What are you letting them do to me? Why?’”
Some children remember the needle pain and quickly start to internalize the fear. That’s the fear Julia Cramer witnessed when her 3-year-old daughter, Maya, had to get blood drawn for an allergy test at age 2.
“After that, she had a fear of blue gloves,” Cramer said. “I went to the grocery store and she saw someone wearing blue gloves, stocking the vegetables, and she started freaking out and crying.”
Pain management research suggests that needle pokes may be children’s biggest source of pain in the health care system. The problem isn’t confined to childhood vaccinations either. Studies looking at sources of pediatric pain have included children who are being treated for serious illness, have undergone heart surgeries or bone marrow transplants, or have landed in the emergency room.
“This is so bad that many children and many parents decide not to continue the treatment,” said Stefan Friedrichsdorf, a specialist at the University of California-San Francisco’s Stad Center for Pediatric Pain, speaking at the End Well conference in Los Angeles in November.
The distress of needle pain can follow children as they grow and interfere with important preventive care. It is estimated that a quarter of all adults have a fear of needles that began in childhood. Sixteen percent of adults refuse flu vaccinations because of a fear of needles.
Friedrichsdorf said it doesn’t have to be this bad. “This is not rocket science,” he said.
He outlined simple steps that clinicians and parents can follow:
- Apply an over-the-counter lidocaine, which is a numbing cream, 30 minutes before a shot.
- Breastfeed babies, or give them a pacifier dipped in sugar water, to comfort them while they’re getting a shot.
- Use distractions like teddy bears, pinwheels, or bubbles to divert attention away from the needle.
- Don’t pin kids down on an exam table. Parents should hold children in their laps instead.
At Children’s Minnesota, Friedrichsdorf practiced the “Children’s Comfort Promise.” Now he and other health care providers are rolling out these new protocols for children at UCSF Benioff Children’s Hospitals in San Francisco and Oakland. He’s calling it the “Ouchless Jab Challenge.”
If a child at UCSF needs to get poked for a blood draw, a vaccine, or an IV treatment, Friedrichsdorf promises, the clinicians will do everything possible to follow these pain management steps.
“Every child, every time,” he said.
It seems unlikely that the ouchless effort will make a dent in vaccine hesitancy and refusal driven by the anti-vaccine movement, since the beliefs that drive it are often rooted in conspiracies and deeply held. But that isn’t necessarily Friedrichsdorf’s goal. He hopes that making routine health care less painful can help sway parents who may be hesitant to get their children vaccinated because of how hard it is to see them in pain. In turn, children who grow into adults without a fear of needles might be more likely to get preventive care, including their yearly flu shot.
In general, the onus will likely be on parents to take a leading role in demanding these measures at medical centers, Friedrichsdorf said, because the tolerance and acceptance of children’s pain is so entrenched among clinicians.
Diane Meier, a palliative care specialist at Mount Sinai, agrees. She said this tolerance is a major problem, stemming from how doctors are usually trained.
“We are taught to see pain as an unfortunate, but inevitable side effect of good treatment,” Meier said. “We learn to repress that feeling of distress at the pain we are causing because otherwise we can’t do our jobs.”
During her medical training, Meier had to hold children down for procedures, which she described as torture for them and for her. It drove her out of pediatrics. She went into geriatrics instead and later helped lead the modern movement to promote palliative care in medicine, which became an accredited specialty in the United States only in 2006.
Meier said she thinks the campaign to reduce needle pain and anxiety should be applied to everyone, not just to children.
“People with dementia have no idea why human beings are approaching them to stick needles in them,” she said. And the experience can be painful and distressing.
Friedrichsdorf’s techniques would likely work with dementia patients, too, she said. Numbing cream, distraction, something sweet in the mouth, and perhaps music from the patient’s youth that they remember and can sing along to.
“It’s worthy of study and it’s worthy of serious attention,” Meier said.

This is a Levantine dish, Syrian in origin (although Lebanese cuisine uses it plenty too) and popularly enjoyed all the way up to Turkey, down to Egypt, and across to Armenia. And today, perhaps rather further afield! It’s first and foremost a spicy dip/spread, though it can be lengthened into a sauce, and/or made more substantial by adding an extra protein. We’ll give you the basic recipe though, and let you see where it takes you! Healthwise, it’s very nutritionally dense, mostly thanks to the walnuts and red peppers, though spices and olive oil bring their healthy benefits too.
You will need
- ½ cup chopped walnuts (ideally: toasted)
- 3 red peppers, from a jar (jarred over fresh not only improves the consistency, but also makes it extra gut-healthy due to the fermentation bacteria present; if you must use fresh, roast them first)
- 2 tbsp extra virgin olive oil
- 1 tbsp pomegranate molasses (you can omit if you don’t like sweetness, but this is traditional)
- 1 tbsp tomato purée
- 1 tbsp Aleppo pepper flakes (less, if you don’t like heat) (substitute another hot pepper if necessary)
- ½ bulb garlic, crushed
- 2 tsp ground smoked paprika
- 1 tsp ground cumin
- ½ tsp MSG or 1 tsp low-sodium salt
- Juice of 1 lemon
- Optional: handful of pomegranate seeds
- Optional: herb garnish, e.g. cilantro or parsley
Method
(we suggest you read everything at least once before doing anything)
1) Add everything except the pomegranate seeds and herbs to a blender, and blend to a smooth consistency.
2) Add the pomegranate seeds and herbs, as a garnish.
3) Serve! Can be enjoyed as a dip (perhaps using our Homemade Healthy Flatbreads recipe), or as a spread, or used as a sauce poured over chickpeas or some other bulky protein, to make a more substantial dish.
Enjoy!

Kiwi vs Lemon – Which is Healthier?
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Our Verdict
When comparing kiwi to lemon, we picked the kiwi.
Why?
A fairly straightforward one today!
In terms of macros, kiwi has more protein, carbs, and fiber, the ratio of the latter two also giving it the lower glycemic index. An easy win for kiwi here.
In the category of vitamins, kiwi has more of vitamins A, B2, B3, B9, C, E, K, and choline, while lemon has more of vitamins B1 and B6. Yes, that’s right, lemon didn’t even win on the vitamin C that it’s famous for. In any case, a clear 8:2 win for kiwi.
Looking at minerals, kiwi has more calcium, copper, magnesium, manganese, phosphorus, potassium, and zinc, while lemon has more iron and selenium. So, looking at this 7:2 win for kiwi, you might want to reconsider that “glass of lemon water to replenish minerals” trend!
None of this is to knock lemons, by the way; lemons are still a very respectable fruit, nutritionally. Probably very few people are out there eating lemons the way one might eat kiwi…
(writer’s note: I say “very few”, as once upon a time when my son was small, I remember coming into the kitchen to find he had helped himself to lemon wedges and was just eating them, so it can happen. But I also one time when he was just as small, found him drinking hot sauce directly from the bottle, so hey, he clearly already enjoyed strong flavors. Lest I seem a very inattentive mother, I’ll say in my defense that our kitchen has no real toddler-height hazards when the oven is cold, and those items were from the bottom of the fridge, so easy to access if I leave the room for a moment to grab something)
…but what we do want to say here is: if you don’t care for lemons so much, you’re not missing out. If the lemon water isn’t calling to you, you can skip it guilt-free.
In any case, do enjoy either or both, but kiwi’s the clear winner here!

The 3 Phases Of Fat Loss (& How To Do It Right!)
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Cori Lefkowith, of “Redefining Strength” and “Strength At Any Age” fame, has advice:
As easy as 1, 2, 3?
Any kind of fat loss plan will not work unless it takes into account that the body can and will adapt to a caloric deficit, meaning that constantly running a deficit will only ever yield short term results, followed by regaining weight (and feeling hungry the whole time). So, instead, if fat loss is your goal, you might want to consider doing it in these stages:
1. Lifestyle adjustments (main phase)
Focus on sustainable, gradual improvements in diet and workouts.
- Key strategies:
- Start with small, manageable changes, for example focusing on making your protein intake around 30–35% of your total calories.
- Track your current habits to identify realistic adjustments.
- Balance strength training and cardio, as maintaining your muscle is (and will remain) important.
- Signs of Progress:
- Slow changes in the numbers on the scale (up to 1 lb/week).
- Inches being lost (but probably not many), improved energy levels, and stable performance in workouts.
Caution: avoid feelings of extreme hunger or restriction. This is not supposed to be arduous.
2. Mini cut (short-term intensive)
Used for quick fat loss or breaking plateaus; lasts 7–14 days.
- Key strategies:
- Larger calorie deficit (e.g: 500 calories).
- High protein intake (40–50% of your total calories).
- Focus on strength training and reduce cardio, to avoid muscle loss.
- Signs of Progress:
- Rapid scale changes (up to 5 lbs/week).
- Reduced bloating, potential energy dips, and cravings.
- Temporary performance stagnation in workouts. Don’t worry about this; it’s expected and fine.
Caution: do not exceed 21 days, to avoid the metabolic adaptation that we talked about.
3. Diet break (rest & reset)
A maintenance period to recharge mentally and physically, typically lasting 7–21 days.
- Key strategies:
- Gradually increase calories (200–500) to maintenance level.
- Focus on performance goals and reintroducing foods you enjoy.
- Combine strength training with steady-state cardio.
- Signs of Progress:
- Increased energy, improved workout performance, and feeling fuller.
- Scale may fluctuate initially but stabilize or decrease by the end.
- Inches will be lost as muscle is built and fat is burned.
The purpose of this third stage is to prevent metabolic adaptation, regain motivation, and (importantly!) test maintenance.
