For any unfamiliar: lucid dreaming means being aware that one is dreaming, while dreaming, and exercising a degree of control over the dream. Superficially, this is fun. But if one really wants to go deeper into it, it can be a lot more:
Dr. Stephen LaBerge takes a science-based approach to lucid dreaming, and in this work provides not only step-by-step instructions of several ways of inducing lucid dreaming, but also, opens the reader’s mind to things that can be done there beyond the merely recreational:
In lucid dreams, he argues and illustrates, it’s possible to talk to parts of one’s own subconscious (Inception, anyone? Yes, this book came first) and get quite an amount of self-therapy done. And that hobby you wish you had more time to practice? The possibilities just became limitless. And who wouldn’t want that?

How To Grow New Brain Cells (At Any Age)
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.
How To Grow New Brain Cells (At Any Age)
It was long believed that brain growth could not occur later in life, due to expending our innate stock of pluripotent stem cells. However, this was mostly based on rodent studies.
Rodent studies are often used for brain research, because it’s difficult to find human volunteers willing to have their brains sliced thinly (so that the cells can be viewed under a microscope) at the end of the study.
However, neurobiologist Dr. Maura Boldrini led a team that did a lot of research by means of autopsies on the hippocampi of (previously) healthy individuals ranging in age from 14 to 79.
What she found is that while indeed the younger subjects did predictably have more young brain cells (neural progenitors and immature neurons), even the oldest subject, at the age of 79, had been producing new brain cells up until death.
Read her landmark study: Human Hippocampal Neurogenesis Persists throughout Aging
There was briefly a flurry of news articles about a study by Dr. Shawn Sorrels that refuted this, however, it later came to light that Dr. Sorrels had accidentally destroyed his own evidence during the cell-fixing process—these things happen; it’s just unfortunate the mistake was not picked up until after publication.
A later study by a Dr. Elena Moreno-Jiménez fixed this flaw by using a shorter fixation time for the cell samples they wanted to look at, and found that there were tens of thousands of newly-made brain cells in samples from adults ranging from 43 to 87.
Now, there was still a difference: the samples from the youngest adult had 30% more newly-made braincells than the 87-year-old, but given that previous science thought brain cell generation stopped in childhood, the fact that an 87-year-old was generating new brain cells 30% less quickly than a 43-year-old is hardly much of a criticism!
As an aside: samples from patients with Alzheimer’s also had a 30% reduction in new braincell generation, compared to samples from patients of the same age without Alzheimer’s. But again… Even patients with Alzheimer’s were still growing some new brain cells.
Read it for yourself: Adult hippocampal neurogenesis is abundant in neurologically healthy subjects and drops sharply in patients with Alzheimer’s disease
Practical advice based on this information
Since we can do neurogenesis at any age, but the rate does drop with age (and drops sharply in the case of Alzheimer’s disease), we need to:
Feed your brain. The brain is the most calorie-consuming organ we have, by far, and it’s also made mostly of fat* and water. So, get plenty of healthy fats, and get plenty of water.
*Fun fact: while depictions in fiction (and/or chemically preserved brains) may lead many to believe the brain has a rubbery consistency, the untreated brain being made of mostly fat and water gives it more of a blancmange-like consistency in reality. That thing is delicate and spatters easily. There’s a reason it’s kept cushioned inside the strongest structure of our body, far more protected than anything in our torso.
Exercise. Specifically, exercise that gets your blood pumping. This (as our earlier-featured video today referenced) is one of the biggest things we can do to boost Brain-Derived Neurotrophic Factor, or BDNF.
Here be science: Brain-Derived Neurotrophic Factor, Depression, and Physical Activity: Making the Neuroplastic Connection
However, that’s not the only way to increase BDNF; another is to enjoy a diet rich in polyphenols. These can be found in, for example, berries, tea, coffee, and chocolate. Technically those last two are also botanically berries, but given how we usually consume them, and given how rich they are in polyphenols, they merit a special mention.
See for example: Effects of nutritional interventions on BDNF concentrations in humans: a systematic review
Some supplements can help neuron (re)growth too, so if you haven’t already, you might want to check out our previous main feature on lion’s mane mushroom, a supplement which does exactly that.

Understanding Cataracts
Cataracts are natural and impact everyone.
That’s a bit of a daunting opening line, but as Dr. Michele Lee, a board-certified ophthalmologist, explains, cataracts naturally develop with age, and can be accelerated by factors such as trauma, certain medications, and specific eye conditions.
We know how important your vision is to you (we’ve had great feedback about the book Vision for Life) as well as our articles on how glasses impact your eyesight and the effects of using eye drops.
While complete prevention isn’t possible, steps such as those mentioned below can be taken to slow their progression.
Here is an overview of the video’s first 3 takeaways. You can watch the whole video below.
Protect Your Eyes from Sunlight
Simply put, UV light damages lens proteins, which (significantly) contributes to cataracts. Wearing sunglasses can supposedly prevent up to 20% of cataracts caused by UV exposure.
Moderate Alcohol Consumption
We all, at some level, know that alcohol consumption doesn’t do us any good. Your eye health isn’t an exception to the rule; alcohol has been shown to contribute to cataract development.
If you’re looking at reducing your alcohol use, try reading this guide on lowering, or eradicating, alcohol consumption.
Avoid Smoking
Smokers are 2-3 times more likely to develop cataracts. Additionally, ensure good ventilation while cooking to avoid exposure to harmful indoor smoke.
See all 5 steps in the below video:

How community health screenings get more people of color vaccinated
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.
U.S. preventive health screening rates dropped drastically at the height of the COVID-19 pandemic. They have yet to go back to pre-pandemic levels, especially for Black and Latine communities.
Screenings, or routine medical checkups, are important ways to avoid and treat disease. They’re key to finding problems early on and can even help save people’s lives.
Community health workers say screenings are also a key to getting more people vaccinated. Screening fairs provide health workers the chance to build rapport and trust with the communities they serve, while giving their clients the chance to ask questions and get personalized recommendations according to their age, gender, and family history.
But systemic barriers to health care can often keep people from marginalized communities from accessing recommended screenings, exacerbating racial health disparities.
Public Good News spoke with Dr. Marie-Jose Francois, president and chief executive officer, and April Johnson, outreach coordinator, at the Center for Multicultural Wellness and Prevention (CMWP), in Central Florida, to learn how they promote the benefits of screening and leverage screenings for vaccination outreach among their diverse communities.
Here’s what they said.
[Editor’s note: This content has been edited for clarity and length.]
PGN: What is CMWP’s mission? How does vaccine outreach fit into the work you do in the communities you serve?
Dr. Marie-Jose Francois: Since 1995, our mission has been to enhance the health, wellness, and quality of life for diverse populations in Central Florida. At the beginning, our main focus was education, wellness, and screening for HIV/AIDS, and we continue to do case management for HIV screening and testing.
When the issue of COVID-19 came into the picture, we included COVID-19 information and education and stressed the importance of screening and receiving vaccinations during all of our outreach activities.
We try to meet the community where they are. Because there is so much misconception—and taboo—in regard to immunization.
April Johnson: So our job is to disperse accurate information. And how we do that is we go into rural communities. We build partnerships with local apartment complexes, hair salons, nail salons, laundromats, and provide a little community engagement, where people just hang out in different areas.
We build gatekeepers in those communities because you first have to get in there. You have to know that they trust you. Being in this field for about 30 years, I’ve [learned that] flexibility is key. Because sometimes you can’t get them from 9 to 5, or [from] Monday through Friday. So, you have to be very flexible in doing the outreach portion in order to get what you need.
I’ve built collaborations with senior citizen centers, community centers, schools, clinics, churches in Orlando and [in] different areas in Orange, Osceola, Seminole, and Lake counties. And we also partner with other community-based organizations to try to make it like a one-stop shop. So, partnership is a big thing.
PGN: How do you promote the importance of preventive screenings in the communities you serve?
M.F.: We try to make them view their health in a more comprehensive way, for them to understand the importance of screening. [That] self care is key, and for them to not be afraid.
We empower them to know what to ask when they go to the doctor. We ask them, ‘Do you know your status? Do you know your numbers?’
For example, if you go to the doctor, do you know your blood pressure? If you’re diabetic? Do you know your hemoglobin (A1C)? Do you know your cholesterol levels?
And now, [we also ask them]: ‘Have you received your flu shot for the year? Have you received all of your vaccine doses for COVID-19?’ We are even adding the mpox vaccine now, based on risk factors.
[We recommend they] ask their provider. For women, [we ask], ‘When do you need to have your mammogram?’ For the men, ‘You need to ask about your PSA and also about when and when to have your colonoscopy based on your age.’
We also try to explain to the community that the more they know their family history, the more they can engage in their own health. Because sometimes you have mom and dad who have a history of cancer. They have a history of diabetes or blood pressure—and they don’t talk to their children. So, we try to [recommend they] talk to their children. Your own family needs to know what’s going on so they can be proactive in their screenings.
PGN: What strategies or methods have you found most effective in getting people screened?
M.F.: Not everybody wants to be screened, not everybody wants to receive vaccines.
But with patience, just give them the facts. It goes right back to education, people have to be assured.
When you talk to them about COVID, or even HIV, you may hear them say, ‘Oh, I don’t see myself at risk for HIV.’ But we have to repeat to them that the more they get screened to make sure they’re OK, the better it is for them. ‘The more you use condoms, [the] safer it is for you.’
In Haitian culture, they listen to the radio. So we use the radio as a tool to educate and deliver information [to] get vaccinated, wash your hands. ‘If you’re coughing, cover your mouth. If you have a fever, wear your masks. Call your doctor.’
In our target population, we have people who have chronic conditions. We have people with HIV. So, we have to motivate them to receive the flu vaccine, to receive the COVID vaccine, to receive that RSV [vaccine], or to get the mpox vaccine. We have people with diabetes, high blood pressure, high cholesterol, depressed immune systems. We have people with lupus, we have people with sickle cell disease.
So, this is a way to [ensure that] whomever you’re talking to one-on-one understands the value of being safe.

Debate over tongue tie procedures in babies continues. Here’s why it can be beneficial for some infants
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.
There is increasing media interest about surgical procedures on new babies for tongue tie. Some hail it as a miracle cure, others view it as barbaric treatment, though adverse outcomes are rare.
Tongue tie occurs when the tissue under the tongue is attached to the lower gum or floor of the mouth in a way that can restrict the movement or range of the tongue. This can impact early breastfeeding in babies. It affects an estimated 8% of children under one year of age.
While there has been an increase in tongue tie releases (also called division or frenotomy), it’s important to keep this in perspective relative to the increase in breastfeeding rates.
The World Health Organization recommends exclusive breastfeeding for the first six months of life, with breastfeeding recommended into the second year of life and beyond for the health of mother and baby as well as optimal growth. Global rates of breastfeeding infants for the first six months have increased from 38% to 48% over the past decade. So, it is not surprising there is also an increase in the number of babies being referred globally with breastfeeding challenges and potential tongue tie.
An Australian study published in 2023 showed that despite a 25% increase in referrals for tongue tie division between 2014 and 2018, there was no increase in the number of tongue tie divisions performed. Tongue tie surgery rates increased in Australia in the decade from 2006 to 2016 (from 1.22 per 1,000 population to 6.35) for 0 to 4 year olds. There is no data on surgery rates in Australia over the last eight years.
Tongue tie division isn’t always appropriate but it can make a big difference to the babies who need it. More referrals doesn’t necessarily mean more procedures are performed.
How tongue tie can affect babies
When tongue tie (ankyloglossia) restricts the movement of the tongue, it can make it more difficult for a baby to latch onto the mother’s breast and painlessly breastfeed.
Earlier this month, the International Consortium of oral Ankylofrenula Professionals released a tongue tie position statement and practice guideline. Written by a range of health professionals, the guidelines define tongue tie as a functional diagnosis that can impact breastfeeding, eating, drinking and speech. The guidelines provide health professionals and families with information on the assessment and management of tongue tie.
Tongue tie release has been shown to improve latch during breastfeeding, reduce nipple pain and improve breast and bottle feeding. Early assessment and treatment are important to help mothers breastfeed for longer and address any potential functional problems.
Where to get advice
If feeding isn’t going well, it may cause pain for the mother or there may be signs the baby isn’t attaching properly to the breast or not getting enough milk. Parents can seek skilled help and assessment from a certified lactation consultant or International Board-Certified Lactation Consultant who can be found via online registry.
Alternatively, a health professional with training and skills in tongue tie assessment and division can assist families. This may include a doctor, midwife, speech pathologist or dentist with extended skills, training and experience in treating babies with tongue tie.
When access to advice or treatment is delayed, it can lead to unnecessary supplementation with bottle feeds, early weaning from breastfeeding and increased parental anxiety.
Getting a tongue tie assessment
During assessment, a qualified health professional will collect a thorough case history, including pregnancy and birth details, do a structural and functional assessment, and conduct a comprehensive breastfeeding or feeding assessment.
They will view and thoroughly examine the mouth, including the tongue’s movement and lift. The appearance of where the tissue attaches to the underside of the tongue, the ability of the tongue to move and how the baby can suck also needs to be properly assessed.
Treatment decisions should focus on the concerns of the mother and baby and the impact of current feeding issues. Tongue tie division as a baby is not recommended for the sole purpose of avoiding speech problems in later life if there are no feeding concerns for the baby.
Treatment options
The Australian Dental Association’s 2020 guidelines provide a management pathway for babies diagnosed with tongue tie.
Once feeding issues are identified and if a tongue tie is diagnosed, non-surgical management to optimise positioning, latch and education for parents should be the first-line approach.
If feeding issues persist during follow-up assessment after non-surgical management, a tongue tie division may be considered. Tongue tie release may be one option to address functional challenges associated with breastfeeding problems in babies.
There are risks associated with any procedure, including tongue tie release, such as bleeding. These risks should be discussed with the treating practitioner before conducting any laser, scissor or scalpel tongue tie procedure.
Post-release support by a certified lactation consultant or feeding specialist is necessary after a tongue tie division. A post-release treatment plan should be developed by a team of health professionals including advice and support for breastfeeding to address both the mother and baby’s individual needs.

Super Joints – by Pavel Tsatsouline
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.
For those of us for whom mobility and pain-free movement are top priorities, this book has us covered. So what’s different here, compared to your average stretching book?
It’s about functional strength with the stretches. The author’s background as a special forces soldier means that his interest was not in doing arcane yoga positions so much as being able to change direction quickly without losing speed or balance, get thrown down and get back up without injury, twist suddenly without unpleasantly wrenching anything (of one’s own, at least), and generally be able to take knocks without taking damage.
While we are hopefully not having to deal with such violence in our everyday lives, the robustness of body that results from these exercises is one that certainly can go a long way to keep us injury-free.
The exercises themselves are well-described, clearly and succinctly, with equally clear illustrations.
Note: the paperback version is currently expensive, probably due to supply and demand, but if you select the Kindle version, it’s much cheaper with no loss of quality (because the illustrations are black-on-white line-drawings and very clear; perfect for Kindle e-ink)
The style of the book is very casual and conversational, yet somehow doesn’t let that distract it from being incredibly information dense; there is no fluff here, just valuable guidance.
Bottom line: if you would like to be more robust with non-nonsense exercises, then this book is a fine choice.

Which Plant Milk?
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.
Plant-based milks—what’s best?
You asked us to look at some popular plant milks and their health properties, and we said we’d do a main feature, so here it is!
We’ll also give a quick nod to environmental considerations at the end too (they might not be quite what you expect!). That said, as a health and productivity newsletter, we’ll be focusing on the health benefits.
While we can give a broad overview, please note that individual brands may vary, especially in two important ways:
- Pro: many (most?) brands of plant milks fortify their products with extra vitamins and minerals, especially vitamin D and calcium.
- Con: some brands also add sugar.
So, by all means use this guide to learn about the different plants’ properties, and/but still do check labels later.
Alternatively, consider making your own!
- Pros: no added sugar + cheaper
- Cons: no added vitamins and minerals + some equipment required
Almond milk
Almond milk is low in carbs and thus good for a carb-controlled diet. It’s also high in vitamin E and a collection of minerals.
Oat milk
Oats are one of the healthiest “staple foods” around, and while drinking oat milk doesn’t convey all the benefits, it does a lot. It also has one of the highest soluble fiber contents of any milk, which is good for reducing LDL (bad) cholesterol levels.
See for example: Consumption of oat milk for 5 weeks lowers serum cholesterol and LDL cholesterol in free-living men with moderate hypercholesterolemia
Coconut milk
Coconut has a higher fat content than most plant milks, but also contains medium-chain triglycerides (MCTs). These raise HDL (good) cholesterol levels.
Read the study: How well do plant based alternatives fare nutritionally compared to cow’s milk?
Hemp milk
Being made from hemp seeds that contain a lot of protein and healthy fats (including omega-3 and omega-6), hemp milk packs a nutritious punch. It’s carb-free. It’s also THC-free, in case you were wondering, which means no, it does not have psychoactive effects.
Pea milk
It’s very high in protein, and contains an array of vitamins and minerals. It’s not very popular yet, so there isn’t as much research about it. This 2021 study found that it had the nutritional profile the closest to cow’s milk (beating soy by a narrow margin) and praised it as a good alternative for those with a soy allergy.
This is Research Review Monday so we try to stick to pure science, but for your interest… here’s an interesting pop-science article (ostensibly in affiliation with the pea milk brand, Ripple) about the nutritional qualities of their pea milk specifically, which uses particularly nutrient-dense yellow peas, plus some extra vitamin and mineral fortifications:
Read: Ripple Milk: 6 Reasons Why You Should Try Pea Milk
Soy milk
Perhaps the most popular plant milk, and certainly usually the cheapest in stores. It’s high in protein, similar to cow’s milk. In fact, nutritionally, it’s one of the closest to cow’s milk without involving cows as a middleman. (Did you know three quarters of all soy in the world is grown to feed to livestock, not humans? Now you do).
And no, gentlemen-readers, it won’t have any feminizing effects. The human body can’t use the plant estrogens in soy for that. It does give some isoflavone benefits though, which are broadly good for everyone’s health. See for example this research review with 439 sources of its own:
Read: Soy and Health Update: Evaluation of the Clinical and Epidemiologic Literature
Quick note on flavor: nut milks have the flavor of the nut they were made from. Coconut milk tastes of coconut. The other milks listed above don’t have much of a flavor—which in many cases may be what you want.
Note on environmental considerations:
A lot of us try to be as socially responsible as reasonably possible in our choices, so this may be an influencing factor. In a nutshell:
- Oats and Soy are generally grown as vast monocrops, and these are bad for the environment
- They are still better for the environment than cow’s milk though, as for example most soy is grown to feed to cows, not humans. So including cows in the process means four times as much monocrop farming, plus adds several other environmental issues that are beyond the scope of this newsletter.
- Almonds are particularly resource-intensive when it comes to water use.
- Still nowhere near as much as cows, though.
- Peas are grown in places that naturally have very high rainfall, so are a good option here. Same generally goes for rice, which didn’t make the cut today. (Nor did hazelnuts, sorry—we can only include so much!)
- Hemp is by far and away the most environmentally friendly, assuming it is grown in a climate naturally conducive to such.
- Making plant milk at home is usually most environmentally friendly, depending on where your ingredients came from.
- Literally any plant milk is much more environmentally friendly than cow’s milk.
