You’re Not Forgetful: How To Remember Everything

Elizabeth Filips, medical student busy learning a lot of information, explains how in today’s video:
Active processing
An important thing to keep in mind is that forgetting is an active process, not passive as once believed. It has its own neurotransmitters and pathways, and as such, to improve memory, it’s essential to understand and manage forgetting.
So, how does forgetting occur? Memories are stored with cues or tags, which help retrieve information. However, overloading cues with too much information can cause “transient forgetting”—that is to say, the information is still in there somewhere; you just don’t have the filing system required to retrieve the data. This is the kind of thing that you will try hard to remember at some point in the day when you need it, fail, and then wake up at 3am with an “Aha!” because your brain finally found what you were looking for. So, to avoid that, use unique and strong cues to help improve recall (mnemonics are good for this, as are conceptual anchors).
While memory does not appear to actually be finite, there is some practical truth in the “finite storage” model insofar as learning new information can overwrite previous knowledge, iff your brain mistakes it for an update rather than addition. So for that reason, it’s good to periodically go over old information—in psychology this is called rehearsal, which may conjure theatrical images, but it can be as simple as mentally repeating a phone number, a mnemonic, or visually remembering a route one used to take to go somewhere.
Self-perception affects memory performance. Negative beliefs about one’s memory can worsen performance (so don’t say “I have a bad memory”, even to yourself, and in contrast, find more positive affirmations to make about your memory), and mental health in general plays a significant role in memory. For example, if you have ever had an extended period of depression, then chances are good you have some huge gaps in your memory for that time in your life.
A lot of what we learned in school was wrong—especially what we learned about learning. Traditional (vertical) learning is harder to retain, whereas horizontal learning (connecting topics through shared characteristics) creates stronger, interconnected memories. In short, your memories should tell contextual stories, not be isolated points of data.
Embarking on a new course of study? Yes? (If not, then why not? Pick something!)
It may be difficult at first, but experts memorize things more quickly due to built-up intuition in their field. For example a chess master can glance at a chess board for about 5 seconds and memorize the position—but only if the position is one that could reasonably arise in a game; if the pieces are just placed at random, then their memorization ability plummets to that of the average person, because their expertise has been nullified.
What this means in practical terms: building a “skeleton” framework before learning can enhance memorization through logical connections. For this reason, if embarking on a serious course of study, getting a good initial overview when you start is critical, so that you have a context for the rest of what you learn to go into. For example, let’s say you want to learn a language; if you first quickly do a very basic bare-bones course, such as from Duolingo or similar, then even though you’ll have a very small vocabulary and a modest grasp of grammar and make many mistakes and have a lot of holes in your knowledge, you now have somewhere to “fit” every new word or idea you learn. Same goes for other fields of study; for example, a doctor can be told about a new drug and remember everything about it immediately, because they understand the systems it interacts with, understand how it does what it does, and can compare it mentally to similar drugs, and they thus have a “place” in that overall system for the drug information to reside. But for someone who knows nothing about medicine, it’s just a lot of big words with no meaning. So: framework first, details later.

Bacopa Monnieri: A Well-Evidenced Cognitive Enhancer
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.
Bacopa monnieri: a powerful nootropic
Bacopa monnieri is one of those “from traditional use” herbs that has made its way into science.
It’s been used for at least 1,400 years in Ayurvedic medicine, for cognitive enhancement, against anxiety, and some disease-specific treatments.
See: Pharmacological attributes of Bacopa monnieri extract: current updates and clinical manifestation
What are its claimed health benefits?
Bacopa monnieri is these days mostly sold and bought as a nootropic, and that’s what the science supports best.
Nootropic benefits claimed:
- Improves attention, learning, and memory
- Reduces depression, anxiety, and stress
- Reduces restlessness and impulsivity
Other benefits claimed:
- Antioxidant properties
- Anti-inflammatory properties
- Anticancer properties
What does the science say?
Those last three, the antioxidant / anti-inflammatory / anticancer properties, when something has one of those qualities it often has all three, because there are overlapping systems at hand when it comes to oxidative stress, inflammation, and cellular damage.
Bacopa monnieri is no exception to this “rule of thumb”, and/but studies to support these benefits have mostly been animal studies and/or in vitro studies (i.e., cell cultures in a petri dish in lab conditions).
For example:
- Inhibition of lipoxygenases and cyclooxygenase-2 enzymes by extracts isolated from Bacopa monnieri
- Assessing the anti-inflammatory effects of Bacopa-derived bioactive compounds using network pharmacology and in vitro studies
- The evolving roles of Bacopa monnieri as potential anticancer agent: a review
In the category of antioxidant and anti-inflammatory effects in the brain, sometimes results differ depending on the test population, for example:
- Neuroprotective effects of Bacopa monnieri in experimental model of dementia (it worked for rats)
- Use of Bacopa monnieri in the treatment of dementia due to Alzheimer’s disease: systematic review of randomized controlled trials (it didn’t work for humans)
Anything more promising than that?
Yes! The nootropic effects have been much better-studied in humans, and with much better results.
For example, in this 12-week study in healthy adults, taking 300mg/day significantly improved visual information processing, learning, and memory (tested against placebo):
The chronic effects of an extract of Bacopa monnieri on cognitive function in healthy human subjects
Another 12-week study showed older adults enjoyed the same cognitive enhancement benefits as their younger peers:
Children taking 225mg/day, meanwhile, saw a significant reduction in ADHD symptoms, such as restlessness and impulsivity:
And as for the mood benefits, 300mg/day significantly reduced anxiety and depression in elderly adults:
In summary
Bacopa monnieri, taken at 300mg/day (studies ranged from 225mg/day to 600mg/day, but 300mg is most common) has well-evidenced cognitive benefits, including:
- Improved attention, learning, and memory
- Reduced depression, anxiety, and stress
- Reduced restlessness and impulsivity
It may also have other benefits, including against oxidative stress, inflammation, and cancer, but the research is thinner and/or not as conclusive for those.

As ever, we don’t sell it (or anything else), but for your convenience, here is an example product on Amazon.

Matcha is having a moment. What are the health benefits of this green tea drink?
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.
Matcha has experienced a surge in popularity in recent months, leading to reports of global shortages and price increases.
If you haven’t been caught up in the craze, matcha is a powdered version of green tea. On a cafe menu you might see a hot or iced matcha latte, or even a matcha-flavoured cake or pastry. A quick google brings up countless recipes incorporating matcha, both sweet and savoury.
Retailers and cafe owners have suggested the main reasons for matcha’s popularity include its “instagrammable” looks and its purported health benefits.
But what are the health benefits of matcha? Here’s what the evidence says.
Rawpixel.com/Shutterstock First, what is matcha?
Matcha is a finely ground powder of green tea leaves, which come from the plant Camellia sinensis. This is the same plant used to make green and black tea. However, the production process differentiates matcha from green and black tea.
For matcha, the tea plant is grown in shade. Once the leaves are harvested, they’re steamed and dried and the stems are removed. Then the leaves are carefully ground at controlled temperatures to form the powder.
The production process for green tea is simpler. The leaves are picked from the unshaded plants, heated and then dried. We then steep the dried leaves in hot water to get tea (whereas with matcha the whole leaf is consumed).
With black tea, after the leaves are picked they’re exposed to air, which leads to oxidation. This makes the leaves black and gives the tea a different flavour.
In countries such as Japan, matcha is traditionally whisked with water and served in a stone bowl. Charlotte May/Pexels A source of phytonutrients
Phytonutrients are chemical compounds found in plants which have a range of benefits for human health. Matcha contains several.
Chlorophyll gives plants such as Camellia sinensis their green colour. There’s some evidence chlorophyll may have health benefits – including anti-inflammatory, anti-cancer and anti-obesity effects – due to its antioxidant properties. Antioxidants neutralise free radicals, which are unstable molecules that harm our cells.
Theanine has been shown to improve sleep and reduce stress and anxiety. The only other known dietary source of theanine is mushrooms.
Caffeine is a phytonutrient we know well. Aside from increasing alertness, caffeine has also demonstrated antioxidant effects and some protection against a range of chronic and neurodegenerative diseases. However, too much caffeine can have negative side effects.
Interestingly, shading the plants while growing appears to change the nutritional composition of the leaf and may lead to higher levels of these phytonutrients in matcha compared to green tea.
Another compound worth mentioning is called catechins, of which there are several different types. Matcha powder similarly has more catechins than green tea. They are strong antioxidants, which have been shown to have protective effects against bacteria, viruses, allergies, inflammation and cancer. Catechins are also found in apples, blueberries and strawberries.
What are the actual health benefits?
So we know matcha contains a variety of phytonutrients, but does this translate to noticeable health benefits?
A review published in 2023 identified only five experimental studies that have given matcha to people. These studies gave participants about 2–4g of matcha per day (equivalent to 1–2 teaspoons of matcha powder), compared to a placebo, as either a capsule, in tea or in foods. Matcha decreased stress and anxiety, and improved memory and cognitive function. There was no effect on mood.
A more recent study showed 2g of matcha in older people aged 60 to 85 improved sleep quality. However, in younger people aged 27 to 64 in another study, matcha had little effect on sleep.
A study in people with obesity found no difference in the weight loss observed between the matcha group and the control group. This study did not randomise participants, and people knew which group they had been placed in.
It could be hypothesised that given you consume all of the leaf, and given levels of some phytonutrients may be higher due to the growing conditions, matcha may have more nutritional benefits than green tea. But to my knowledge there has been no direct comparison of health outcomes from green tea compared to matcha.
Matcha has grown in popularity – but evidence for its health benefits is still limited. Usanee/Shutterstock There’s lots of evidence for green tea
While to date a limited number of studies have looked at matcha, and none compared matcha and green tea, there’s quite a bit of research on the health benefits of drinking green tea.
A systematic review of 21 studies on green tea has shown similar benefits to matcha for improvements in memory, plus evidence for mood improvement.
There’s also evidence green tea provides other health benefits. Systematic reviews have shown green tea leads to weight loss in people with obesity, lower levels of certain types of cholesterol, and reduced blood pressure. Green tea may also lower the risk of certain types of cancer.
So, if you can’t get your hands on matcha at the moment, drinking green tea may be a good way to get your caffeine hit.
Although the evidence on green tea provides us with some hints about the health benefits of matcha, we can’t be certain they would be the same. Nonetheless, if your local coffee shop has a good supply of matcha, there’s nothing to suggest you shouldn’t keep enjoying matcha drinks.
However, it may be best to leave the matcha croissant or cronut for special occasions. When matcha is added to foods with high levels of added sugar, salt and saturated fat, any health benefits that could be attributed to the matcha may be negated.

Oven-Roasted Ratatouille
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.
This is a supremely low-effort, high-yield dish. It’s a nutritional tour-de-force, and very pleasing to the tastebuds too. We use flageolet beans in this recipe; they are small immature kidney beans. If they’re not available, using kidney beans or really any other legume is fine.
You will need
- 2 large zucchini, sliced
- 2 red peppers, sliced
- 1 large eggplant, sliced and cut into semicircles
- 1 red onion, thinly sliced
- 2 cans chopped tomatoes
- 2 cans flageolet beans, drained and rinsed (or 2 cups same, cooked, drained, and rinsed)
- ½ bulb garlic, crushed
- 2 tbsp extra virgin olive oil
- 1 tbsp balsamic vinegar
- 1 tbsp black pepper, coarse ground
- 1 tbsp nutritional yeast
- 1 tbsp red chili pepper flakes (omit or adjust per your heat preferences)
- ½ tsp MSG or 1 tsp low-sodium salt
- Mixed herbs, per your preference. It’s hard to go wrong with this one, but we suggest leaning towards either basil and oregano or rosemary and thyme. We also suggest having some finely chopped to go into the dish, and some held back to go on the dish as a garnish.
Method
(we suggest you read everything at least once before doing anything)
1) Preheat the oven to 350℉ / 180℃.
2) Mix all the ingredients (except the tomatoes and herbs) in a big mixing bowl, ensuring even distribution.
2) Add the tomatoes. The reason we didn’t add these before is because it would interfere with the oil being distributed evenly across the vegetables.
3) Transfer to a deep-walled oven tray or an ovenproof dish, and roast for 30 minutes.
4) Stir, add the chopped herbs, stir again, and return to the oven for another 30 minutes.
5) Serve (hot or cold), adding any herb garnish you wish to use.
Enjoy!

In Defense of Food – by Michael Pollan
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.
Eat more like the French. Or the Italians. Or the Japanese. Or…
Somehow, whatever we eat is not good enough, and we should always be doing it differently!
Michael Pollan takes a more down-to-Earth approach.
He kicks off by questioning the wisdom of thinking of our food only in terms of nutritional profiles, and overthinking healthy-eating. He concludes, as many do, that a “common-sense, moderate” approach is needed.
And yet, most people who believe they are taking a “common-sense, moderate” approach to health are in fact over-fed yet under-nourished.
So, how to fix this?
He offers us a reframe: to think of food as a relationship, and health being a product of it:
- If we are constantly stressing about a relationship, it’s probably not good.
- On the other hand, if we are completely thoughtless about it, it’s probably not good either.
- But if we can outline some good, basic principles and celebrate it with a whole heart? It’s probably at the very least decent.
The style is very casual and readable throughout. His conclusions, by the way, can be summed up as “Eat real food, make it mostly plants, and make it not too much”.
However, to summarize it thusly undercuts a lot of the actual value of the book, which is the principles for discerning what is “real food” and what is “not too much”.
Bottom line: if you’re tired of complicated eating plans, this book can help produce something very simple, attainable, and really quite good.

Reishi Mushrooms: Which Benefits Do They Really Have?
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.
Reishi Mushrooms
Another Monday Research Review, another mushroom! If we keep this up, we’ll have to rename it “Mushroom Monday”.
But, there’s so much room for things to say, and these are fun guys to write about, as we check the science for any spore’ious claims…
Why do people take reishi?
Popular health claims for the reishi mushroom include:
- Immune health
- Cardiovascular health
- Protection against cancer
- Antioxidant qualities
- Reduced fatigue and anxiety
And does the science agree?
Let’s take a look, claim by claim:
Immune health
A lot of research for this has been in vitro (ie, with cell cultures in labs), but promising, for example:
Immunomodulating Effect of Ganoderma lucidum (Lingzhi) and Possible Mechanism
(that is the botanical name for reishi, and the Chinese name for it, by the way)
That’s not to say there are no human studies though; here it was found to boost T-cell production in stressed athletes:
Cardiovascular health
Here we found a stack of evidence for statistically insignificant improvements in assorted measures of cardiovascular health, and some studies where reishi did not outperform placebo.
Because the studies were really not that compelling, instead of taking up room (and your time) with them, we’re going to move onto more compelling, exciting science, such as…
Protection against cancer
There’s a lot of high quality research for this, and a lot of good results. The body of evidence here is so large that even back as far as 2005, the question was no longer “does it work” or even “how does it work”, but rather “we need more clinical studies to find the best doses”. Researchers even added:
❝At present, lingzhi is a health food supplement to support cancer patients, yet the evidence supporting the potential of direct in vivo anticancer effects should not be underestimated.❞
Check it out:
Anticancer effects of Ganoderma lucidum: a review of scientific evidence
Just so you know we’re not kidding about the weight of evidence, let’s drop a few extra sources:
- Ganoderma lucidum: a rational pharmacological approach to surmount cancer
- Ganoderma lucidum as an anti-cancer agent
- Extract from Ganoderma lucidum suppresses cervical cancer cell malignancy
- Ganoderma lucidum spore oil induces apoptosis of breast cancer cells
- Ganoderma lucidum enhances carboplatin chemotherapy effect
- Ganoderma lucidum inhibits prostate cancer cell migration
- Ganoderma lucidum fruiting body extracts inhibit colorectal cancer
- Inhibitory activity of medicinal mushroom Ganoderma lucidum on colorectal cancer
- Ganoderma lucidum (reishi mushroom) for cancer treatment
By the way, we shortened most of those titles for brevity, but almost all of the continued with “by” followed by a one-liner of how it does it.
So it’s not a “mysterious action” thing, it’s a “this is a very potent medicine and we know how it works” thing.
Antioxidant qualities
Here we literally only found studies to say no change was found, one that found a slight increase of antioxidant levels in urine. It’s worth noting that levels of a given thing (or its metabolites, in the case of some things) in urine are often quite unhelpful regards knowing what’s going on in the body, because we get to measure only what the body lost, not what it gained/kept.
So again, let’s press on:
Reduced fatigue and anxiety
Most of the studies for this that we could find pertained to health-related quality of life for cancer patients specifically, so (while they universally give glowing reports of reishi’s benefits to health and happiness of cancer patients), that’s a confounding factor when it comes to isolating its effects on reduction of fatigue and anxiety in people without cancer.
Here’s one that looked at it in the case of reduction of fatigue, anxiety, and other factors, in patients without cancer (but with neurathenia), in which they found it was “significantly superior to placebo with respect to the clinical improvement of symptoms”.
Summary:
- Reishi mushroom’s anti-cancer properties are very, very clear
- There is also good science to back immune health claims
- It also has been found to significantly reduce fatigue and anxiety in unwell patients (we’d love to see more studies on its benefits in otherwise healthy people, though)
