Hello Sleep – by Dr. Jade Wu

We’ve reviewed other sleep books before, so what makes this one stand out?
Mostly, it’s because this one takes quite a different approach.
While still giving a nod to the sensible advice you’ve already read in many places (including here at 10almonds), Dr. Wu looks to help the reader avoid falling into the trap (or: help the reader get out of the trap, if already there) of focussing so much on getting better sleep that it becomes an all-consuming stressor that takes up much of the day thinking about it, and guess what, much of the night too, because you’re busy working out how sleep-deprived you’re going to be tomorrow.
Instead, Dr. Wu recommends to work with your body rather than against it, worry less, and ultimately sleep better. Of course, the “how” of this is what makes most of the book.
She does also give chapters on things that may be different for you, based on such things as hormones, age, or medical conditions.
The writing style is pop-science but with frequent references to scientific papers as appropriate, making good science very accessible.
Bottom line: if you’ve tried everything else and/but good sleep still eludes you, this book will help you to end the battle and make friends with your sleep (a metaphor the author uses throughout the book, by the way).

The Bitter Truth About Coffee (or is it?)
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.
The Bitter Truth About Coffee (or is it?)
Yesterday, we asked you for your (health-related) views on coffee. The results were clear: if we assume the responses to be representative, we’re a large group of coffee-enthusiasts!
One subscriber who voted for “Coffee is a healthy stimulant, hydrating, and full of antioxidants” wrote:
❝Not so sure about how hydrating it is! Like most food and drink, moderation is key. More than 2 or 3 cups make me buzz! Just too much.❞
And that fine point brings us to our first potential myth:
Coffee is dehydrating: True or False?
False. With caveats…
Coffee, in whatever form we drink it, is wet. This may not come as a startling revelation, but it’s an important starting point. It’s mostly water. Water itself is not dehydrating.
Caffeine, however, is a diuretic—meaning you will tend to pee more. It achieves its diuretic effect by increasing blood flow to your kidneys, which prompts them to release more water through urination.
See: Effect of caffeine on bladder function in patients with overactive bladder symptoms
How much caffeine is required to have a diuretic effect? About 4.5 mg/kg.
What this means in practical terms: if you weigh 70kg (a little over 150lbs), 4.5×70 gives us 315.
315mg is about how much caffeine might be in six shots of espresso. We say “might” because while dosage calculations are an exact science, the actual amount in your shot of espresso can vary depending on many factors, including:
- The kind of coffee bean
- How and when it was roasted
- How and when it was ground
- The water used to make the espresso
- The pressure and temperature of the water
…and that’s all without looking at the most obvious factor: “is the coffee decaffeinated?”
If it doesn’t contain caffeine, it’s not diuretic. Decaffeinated coffee does usually contain tiny amounts of caffeine still, but with nearer 3mg than 300mg, it’s orders of magnitude away from having a diuretic effect.
If it does contain caffeine, then the next question becomes: “and how much water?”
For example, an Americano (espresso, with hot water added to make it a long drink) will be more hydrating than a ristretto (espresso, stopped halfway through pushing, meaning it is shorter and stronger than a normal espresso).
A subscriber who voted for “Coffee messes with sleep, creates dependency, is bad for the heart and gut, and is dehydrating too” wrote:
❝Coffee causes tachycardia for me so staying away is best. People with colon cancer are urged to stay away from coffee completely.❞
These are great points! It brings us to our next potential myth:
Coffee is bad for the heart: True or False?
False… For most people.
Some people, like our subscriber above, have an adverse reaction to caffeine, such as tachycardia. An important reason (beyond basic decency) for anyone providing coffee to honor requests for decaff.
For most people, caffeine is “heart neutral”. It doesn’t provide direct benefits or cause direct harm, provided it is enjoyed in moderation.
See also: Can you overdose on caffeine?
Some quick extra notes…
That’s all we have time for in myth-busting, but it’s worth noting before we close that coffee has a lot of health benefits; we didn’t cover them today because they’re not contentious, but they are interesting nevertheless:
- Coffee is the world’s biggest source of antioxidants
- 65% reduced risk of Alzheimer’s for coffee-drinkers
- 67% reduced risk of type 2 diabetes for coffee-drinkers
- 43% reduced risk of liver cancer for coffee-drinkers
- 53% reduced suicide risk for coffee-drinkers

Pomegranate’s Health Gifts Are Mostly In Its Peel
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.
Pomegranate Peel’s Potent Potential
Pomegranates have been enjoying a new surge in popularity in some parts, widely touted for their health benefits. What’s not so widely touted is that most of the bioactive compounds that give these benefits are concentrated in the peel, which most people in most places throw away.
They do exist in the fruit too! But if you’re discarding the peel, you’re missing out:
Food Applications and Potential Health Benefits of Pomegranate and its Derivatives
“That peel is difficult and not fun to eat though”
Indeed. Drying the peel, especially freeze-drying it, is a good first step:
❝Freeze drying peels had a positive effect on the total phenolic, tannins and flavonoid than oven drying at all temperature range. Moreover, freeze drying had a positive impact on the +catechin, -epicatechin, hesperidin and rutin concentrations of fruit peel. ❞
Once it is freeze-dried, it is easy to grind it into a powder for use as a nutritional supplement.
“How useful is it?”
Studies with 500mg and 1000mg per day in people with cases of obesity and/or type 2 diabetes saw significant improvements in assorted biomarkers of cardiometabolic health, including blood pressure, blood sugar levels, cholesterol, and hemoglobin A1C:
- Effects of pomegranate extract supplementation on inflammation in overweight and obese individuals: A randomized controlled clinical trial
- Beneficial effects of pomegranate peel extract on plasma lipid profile, fatty acids levels and blood pressure in patients with diabetes mellitus type-2: A randomized, double-blind, placebo-controlled study
It also has anticancer properties:
- Punicalagin, a polyphenol from pomegranate fruit, induces growth inhibition and apoptosis in human PC-3 and LNCaP cells
- Punica granatum (Pomegranate) activity in health promotion and cancer prevention
- The extract from Punica granatum (pomegranate) peel induces apoptosis and impairs metastasis in prostate cancer cells
…and neuroprotective benefits:
- Long-term (15 mo) dietary supplementation with pomegranates attenuates cognitive and behavioral deficits
- Neuroprotective Effects of Pomegranate Peel Extract
- An Evaluation of the Effects of a Non-caffeinated Energy Dietary Supplement on Cognitive and Physical Performance
…and it may protect against osteopenia and osteoporosis, but we only have animal or in vitro studies so far, for example:
- Pomegranate Peel Extract Prevents Bone Loss in a Preclinical Model of Osteoporosis and Stimulates Osteoblastic Differentiation in Vitro
- Pomegranate and its derivatives can improve bone health through decreased inflammation and oxidative stress in an animal model of postmenopausal osteoporosis
Want to try it?
We don’t sell it, but you can buy pomegranates at your local supermarket, or buy the peel extract ready-made from online sources; here’s an example on Amazon for your convenience
(the marketing there is for use of the 100% pomegranate peel powder as a face mask; it also has health benefits for the skin when applied topically, but we didn’t have time to cover that today)

Tilapia vs Cod – 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 tilapia to cod, we picked the tilapia.
Why?
Another case of “that which is more expensive is not necessarily the healthier”!
In terms of macros, tilapia has more protein and fats, as well as more omega-3 (and omega-6). On the downside, tilapia does have relatively more saturated fat, but at 0.94g/100g, it’s not exactly butter.
The vitamins category sees that tilapia has more of vitamins B1, B3, B5, B12, D, and K, while cod has more of vitamins B6, B9, and choline. A moderate win for tilapia.
When it comes to minerals, things are most divided; tilapia has more copper, iron, phosphorus, potassium, manganese, and selenium, while cod has more magnesium and zinc. An easy win for tilapia.
One other thing to note is that both of these fish contain mercury these days (and it’s worth noting: cod has nearly 10x more mercury). Mercury is, of course, not exactly a health food.
So, excessive consumption of either is not recommended, but out of the two, tilapia is definitely the one to pick.

When You Know What You “Should” Do (But Knowing Isn’t The Problem)
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.
When knowing what to do isn’t the problem
Often, we know what we need to do. Sometimes, knowing isn’t the problem!
The topic today is going to be a technique used by therapeutic service providers to help people to enact positive changes in their lives.
While this is a necessarily dialectic practice (i.e., it involves a back-and-forth dialogue), it’s still perfectly possible to do it alone, and that’s what we’ll be focussing on in this main feature.
What is Motivational Interviewing?
❝Motivational interviewing (MI) is a technique that has been specifically developed to help motivate ambivalent patients to change their behavior.❞
Read in full: Motivational Interviewing: An Evidence-Based Approach for Use in Medical Practice
It’s mostly used for such things as helping people reduce or eliminate substance abuse, or manage their weight, or exercise more, things like that.
However, it can be employed for any endeavour that requires motivation and sustained willpower to carry it through.
Three Phases
Motivational Interviewing traditionally has three phases:
- Exploring and understanding the issue at hand
- Guiding and deciding importance and goals
- Choosing and setting an action plan
In self-practice, maybe you can already know and understand what it is that you want/need to change.
If not, consider asking yourself such questions as:
- What does a good day look like? What does a bad day look like?
- If things are not good now, when were they good? What changed?
- If everything were perfect now, what would that look like? How would you know?
Once you have a clear idea of where you want to be, the next thing to know is: how much do you want it? And how confident are you in attaining it?
This is a critical process:
- Give your answers numerically on a scale from 0 to 10
- Whatever your score, ask yourself why it’s not lower. For example, if you scored your motivation 4 and your confidence 2, what factors made your motivation not a lower number? What factors made your confidence not a lower number?
- In the unlikely event that you gave yourself a 0, ask whether you can really afford to scrap the goal. If you can’t, find something, anything, to bring it to at least a 1.
- After you’ve done that, then you can ask yourself the more obvious question of why your numbers aren’t higher. This will help you identify barriers to overcome.
Now you’re ready to choose what to focus on and how to do it. Don’t bite off more than you can chew; it’s fine to start low and work up. You should revisit this regularly, just like you would if you had a counsellor helping you.
Some things to ask yourself at this stage of the motivational self-interviewing:
- What’s a good SMART goal to get you started?
- What could stop you from achieving your goal?
- How could you overcome that challenge?
- What is your backup plan, if you have to scale back your goal for some reason?
A conceptual example: if your goal is to stick to a whole foods Mediterranean diet, but you are attending a wedding next week, then now is the time to decide in advance 1) what personal lines-in-the-sand you will or will not draw 2) what secondary, backup plan you will make to not go too far off track.
The same example in practice: wedding menus often offer meat/fish/vegetarian options, so you might choose the fish or vegetarian, and as for sugar and alcohol, you might limit yourself to “a small slice of wedding cake only; coffee/cheese option instead of dessert”, and “alcohol only for toasts”.
Giving yourself the permission well in advance for small (clearly defined and boundaried!) diversions from the plan, will stop you from falling into the trap of “well, since today’s a cheat-day now…”
Secret fourth stage
The secret here is to keep going back and reassessing at regular intervals. Set your own calendar; you might want to start out weekly and then move to monthly when you’re more strongly on-track.
For this reason, it’s good to keep a journal with your notes from your self-interview sessions, the scores you gave yourself, the goals and plans you set, etc.
When conducting your regular review, be sure to examine what worked for you, and what didn’t (and why). That way, you can practice trial-and-improvement as you go.

Wasting Your Vitamins?
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.
Are you flushing away your vitamins?
Most likely…but you don’t have to.
We all know what a wasteful expense supplements can sometimes be, but you can optimise your intake to get more bang for your buck!
Top Tips for Getting Your Money’s Worth:
- Liquids are better than tablets—the body can’t absorb nutrients from tablets anywhere as easily as it can from liquids, with some saying as low as a 50% absorption rate for tablets, so if your supplement can come in drinkable form, take it that way!
- Capsules are better than tablets—capsules, depending on the kind, contain either a powder (true capsules) or a liquid (softgels). Once the capsule/softgel is broken down in the stomach, it releases its contents, which will now be absorbed as though you took it as a drink.
- Stay hydrated—on that note, your body can only make use of nutrients that it can easily transport, and if you’re dehydrated, the process is sluggish! Having a big glass of water with your supplements will go a long way to helping your body get them where they’re needed.
- Take with black pepper—studies disagree on exactly how much black pepper improves absorption of nutrients. Some say it improves it by 50%, others say as much as 7x better. The truth is probably that it varies from one nutrient to the next, but what is (almost) universally accepted is that black pepper helps you absorb many nutrients you take orally.
- Take with a meal—bonus if you seasoned it with black pepper! But also: many nutrients are best absorbed alongside food, and many are specifically fat-soluble (so you want to take a little fat around the same time for maximum absorption)
- Consider split doses—a lot of nutrients are best absorbed when spread out a bit. Why? Your body can often only absorb so much at once, and what it couldn’t absorb can, depending on the nutrient, pass right through you. So better to space out the doses—breakfast and dinner make for great times to take them.
- Consider cycling—no, not the two-wheeled kind, though feel free to do that too! What cycling means when it comes to supplements is to understand that your body can build a tolerance to some supplements, so you’ll get gradually less effect for the same dose. Combat this by scheduling a break—five days on, two days off is a common schedule—allowing your body to optimise itself in the process!
- Check Medications—and, as is always safe, make sure you check whether any medications you take can interrupt your supplement absorption!

How we can prepare for future public health emergencies
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.
The U.S. is experiencing an increasing number of disease outbreaks and extreme weather events. While state and national preparedness for public health emergencies has improved in some areas, dangerous gaps remain, says a recent report from Trust for America’s Health.
Titled, “Ready or Not 2024: Protecting the Public’s Health from Diseases, Disasters, and Bioterrorism,” the report identifies gaps in national and state preparedness for public health emergencies and provides recommendations for improvement.
Using nine key indicators, the report categorizes all U.S. states and the District of Columbia into three readiness levels: high, medium, and low. The writers hope the report will help policymakers in under-performing states improve public health infrastructure.
Read on to learn more about what the research found and how we can individually prepare for future public health emergencies.
There’s work to be done
The report highlights areas with strong performance as well as those that need improvement.
Some areas with strong performance:
- State public health funding: Most states and the District of Columbia either maintained or increased their public health funding during the 2023 fiscal year.
- Health care labor force preparedness: Most states have started expanding the health care labor force for improved emergency response. As of 2023, 39 states participated in the Nurse Licensure Compact, which allows nurses to work in multiple member states without the need for additional state licenses.
Some areas that need improvement:
- Hospital safety scores: Only 25 percent of acute care hospitals earned the highest patient safety grade in fall 2023. These scores measure health care-associated infection rates, intensive care unit capacity, and other metrics. More high-scoring hospitals would improve preparedness for future public health emergencies.
- Access to paid time off: From March 2018 to March 2023, only 55 percent of U.S. workers used paid time off. Access to paid time off is important for reducing the spread of infectious diseases.
We can all do our part by staying up to date on vaccines
While the report focuses on policy changes that would improve emergency preparedness, Trust for America’s Health’s research identifies one way that we can individually prepare for future public health emergencies: staying up to date on vaccines.
The report found that during the 2022-2023 flu season, only 49 percent of those eligible for the flu vaccine received it. Public health experts are concerned that false claims about COVID-19 vaccines have resulted in overall vaccine hesitancy.
A decline in vaccination rates has led to an uptick in life-threatening, vaccine-preventable diseases, such as measles. Increasing vaccine uptake would prevent the spread of vaccine-preventable diseases and reduce strain on hospital systems during public health crises.
Make sure that you and your children have received all recommended vaccines to prevent severe illness, hospitalization, and death. Learn more about recommended vaccines for adults and children from the CDC.
