Urine has been used to assess health since Ancient Egypt (fun fact: because of Egyptian language having multiple sounds that get transliterated to “a” in English, the condition of passing blood in one’s urine was known as “Aaaaa” ← this word has three syllables; “Aa-a-aa”).
Modern techniques are more advanced than those of times past (for example, diabetes is no longer diagnosed by a urine taste-test), but basic urine inspection is still a very useful indicator of many things. Recognizing changes in urine can even help detect life-threatening conditions early:
Traffic lights?
How urine works: water that we consume is absorbed into the bloodstream and filtered by the kidneys. Urine is essentially blood with actual the blood cells filtered out and/or broken down. The yellow color comes from urochrome, produced during red blood cell breakdown. Here’s how things can happen a little differently:
- Fluorescent yellow: caused by excess vitamin B2 from supplements; harmless.
- Red urine: can indicate blood (bladder cancer, UTIs), hemoglobin, or myoglobin; seek medical attention.
- Dark brown/tea-colored urine: may result from muscle damage or blood cell destruction; requires evaluation.
- Orange urine: caused by dehydration, medications, or liver/bile duct issues (if paired with pale stools).
- Purple urine: UTI bacteria produce pigments that can cause this; treatable with antibiotics.
- Green urine: rare; caused by medications or dyes like methylene blue.
- Frothy/foamy urine: indicates high protein levels, often from kidney damage (e.g. per diabetes and/or hypertension).
- Crystal-clear urine: suggests overhydration, which can dangerously lower sodium levels.
- Dark yellow/amber urine: may mean dehydration; drink more water to maintain a light yellow color.
- Not peeing enough: may indicate severe dehydration or kidney failure; urgent medical attention needed.
- Peeing too much: often linked to diabetes or excessive water intake; can lead to dehydration or low sodium.
- Color-changing urine: port wine color signals porphyria; black urine indicates alkaptonuria (oxidation of homogentisic acid). Both are serious.
Bonus: if you eat a lot of beetroot and then your urine is pink/red/purple, that’s probably just the pigments passing through. If it persists though, then of course, see above.

The Best Kind Of Fiber For Overall Health?
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 Fiber Of Good Health
We’ve written before about how most people in industrialized nations in general, and N. America in particular, do not get nearly enough fiber:
Why You’re Probably Not Getting Enough Fiber (And How To Fix It)
Fiber’s important for many aspects of health, not least of all the heart:
What Matters Most For Your Heart? Eat More (Of This) For Lower Blood Pressure
As well, of course, as being critical for gut health:
Gut Health 101: Making Friends With Your Gut (You Can Thank Us Later)
But is all fiber “prebiotic fiber”, and/or are some better than others?
Beta-glucan
A recent study (it’s a mouse study, but promising in its applicability for humans) examined the health impacts of 5 different fiber types:
- pectin
- β-glucan
- wheat dextrin
- resistant starch
- cellulose (control)
As for health metrics, they measured:
- body weight
- adiposity
- indirect calorimetry
- glucose tolerance
- gut microbiota
- metabolites thereof
What they found was…
❝Only β-glucan supplementation during HFD-feeding decreased adiposity and body weight gain and improved glucose tolerance compared with HFD-cellulose, whereas all other fibers had no effect. This was associated with increased energy expenditure and locomotor activity in mice compared with HFD-cellulose.
All fibers supplemented into an HFD uniquely shifted the intestinal microbiota and cecal short-chain fatty acids; however, only β-glucan supplementation increased cecal butyrate concentrations. Lastly, all fibers altered the small-intestinal microbiota and portal bile acid composition. ❞
If you’d like to read more, the study itself is here:
If you’d like to read less, the short version is that they are all good but β-glucan scored best in several metrics.
It also acts indirectly as a GLP-1 agonist, by the way:
The right fiber may help you lose weight
You may be wondering: what is β-glucan found in?
It’s found in many (non-animal product) foods, but oats, barley, mushrooms, and yeasts are all good sources.
Is it available as a supplement?
More or less; there are supplements that contain it generously, here’s an example product on Amazon, a cordyceps extract, of which >30% is β-glucan.
As an aside, cordyceps itself has many other healthful properties too:
Cordyceps: Friend Or Foe? ← the answer is, it depends! If you’re human, it’s a friend.

Limitless Expanded Edition – by Jim Kwik
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 little flashier in presentation than we usually go for here, but the content is actually very good. Indeed, we’ve featured Jim Kwik before, with different, but also good content—in that case, physical exercises that strengthen the brain.
This time, Kwik (interspersed with motivational speeches that you may or may not benefit from, but they are there) offers a step-by-step course in improving various metrics of cognitive ability. His methods were produced by trial and error, and now have been refined and enjoyed by man. If it sounds like a sales gimmick, it is a bit, but the good news is that everything you need to benefit is in the book; it’s not about upselling to a course or “advanced” books or whatnot.
The style is enthusiastically conversational, and instructions when given (which is often) are direct and clear.
Bottom line: one of the most critical abilities a brain can have is the ability to improve itself, so whatever level your various cognitive abilities are at right now, if you apply this book, you will almost certainly improve in one or more areas, which will make it worth the price of the book.

More Mediterranean – by American’s Test Kitchen
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.
Regular 10almonds readers will know that we talk about the Mediterranean diet often, and with good reason; it’s been for quite a while now the “Gold Standard” when it comes to scientific consensus on what constitutes a good diet for healthy longevity.
However, it’s easy to get stuck in a rut of cooking the same three meals and thinking “I must do something different, but not today, because I have these ingredients and don’t know what to cook” and then when one is grocery-shopping, it’s “I should have researched a new thing to cook, but since I haven’t, I’ll just get the ingredients for what I usually cook, since we need to eat”, and so the cycle continues.
This book will help break you out of that cycle! With (as the subtitle promises) hundreds of recipes, there’s no shortage of good ideas. The recipes are “plant-forward” rather than plant-based per se (i.e. there are some animal products in them), though for the vegetarians and vegans, it’s nothing that’s any challenge to substitute.
Bottom line: if you’re looking for “delicious and nutritious”, this book is sure to put a rainbow on your plate and a smile on your face.

Blind Spots – by Dr. Marty Makary

From the time the US recommended not giving peanuts to infants for the first three years of life “in order to avoid peanut allergies” (whereupon non-exposure to peanuts early in life led to, instead, an increase in peanut allergies and anaphylactic incidents), to the time the US recommended not taking HRT on the strength of the claim that “HRT causes breast cancer” (whereupon the reduced popularity of HRT led to, instead, an increase in breast cancer incidence and mortality), to many other such incidents of very bad public advice being given on the strength of a single badly-misrepresented study (for each respective thing), Dr. Makary puts the spotlight on what went wrong.
This is important, because this is not just a book of outrage, exclaiming “how could this happen?!”, but rather instead, is a book of inquisition, asking “how did this happen?”, in such a way that we the reader can spot similar patterns going forwards.
Oftentimes, this is a simple matter of having a basic understanding of statistics, and checking sources to see if the dataset really supports what the headlines are claiming—and indeed, whether sometimes it suggests rather the opposite.
The style is a little on the sensationalist side, but it’s well-supported with sound arguments, good science, and clear mathematics.
Bottom line: if you’d like to improve your scientific literacy, this book is an excellent illustrative guide.

We’re the ‘allergy capital of the world’. But we don’t know why food allergies are so common in Australian children
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.
Australia has often been called the “allergy capital of the world”.
An estimated one in ten Australian children develop a food allergy in their first 12 months of life. Research has previously suggested food allergies are more common in infants in Australia than infants living in Europe, the United States or Asia.
So why are food allergies so common in Australia? We don’t know exactly – but local researchers are making progress in understanding childhood allergies all the time.
Miljan Zivkovic/Shutterstock What causes food allergies?
There are many different types of reactions to foods. When we refer to food allergies in this article, we’re talking about something called IgE-mediated food allergy. This type of allergy is caused by an immune response to a particular food.
Reactions can occur within minutes of eating the food and may include swelling of the face, lips or eyes, “hives” or welts on the skin, and vomiting. Signs of a severe allergic reaction (anaphylaxis) include difficulty breathing, swelling of the tongue, swelling in the throat, wheeze or persistent cough, difficulty talking or a hoarse voice, and persistent dizziness or collapse.
Recent results from Australia’s large, long-running food allergy study, HealthNuts, show one in ten one-year-olds have a food allergy, while around six in 100 children have a food allergy at age ten.
A food allergy can present with skin reactions. comzeal images/Shutterstock In Australia, the most common allergy-causing foods include eggs, peanuts, cow’s milk, shellfish (for example, prawn and lobster), fish, tree nuts (for example, walnuts and cashews), soybeans and wheat.
Allergies to foods like eggs, peanuts and cow’s milk often present for the first time in infancy, while allergies to fish and shellfish may be more common later in life. While most children will outgrow their allergies to eggs and milk, allergy to peanuts is more likely to be lifelong.
Findings from HealthNuts showed around three in ten children grew out of their peanut allergy by age six, compared to nine in ten children with an allergy to egg.
Are food allergies becoming more common?
Food allergies seem to have become more common in many countries around the world over recent decades. The exact timing of this increase is not clear, because in most countries food allergies were not well measured 40 or 50 years ago.
We don’t know exactly why food allergies are so common in Australia, or why we’re seeing a rise around the world, despite extensive research.
But possible reasons for rising allergies around the world include changes in the diets of mothers and infants and increasing sanitisation, leading to fewer infections as well as less exposure to “good” bacteria. In Australia, factors such as increasing vitamin D deficiency among infants and high levels of migration to the country could play a role.
In several Australian studies, children born in Australia to parents who were born in Asia have higher rates of food allergies compared to non-Asian children. On the other hand, children who were born in Asia and later migrated to Australia appear to have a lower risk of nut allergies.
Meanwhile, studies have shown that having pet dogs and siblings as a young child may reduce the risk of food allergies. This might be because having pet dogs and siblings increases contact with a range of bacteria and other organisms.
This evidence suggests that both genetics and environment play a role in the development of food allergies.
We also know that infants with eczema are more likely to develop a food allergy, and trials are underway to see whether this link can be broken.
Can I do anything to prevent food allergies in my kids?
One of the questions we are asked most often by parents is “can we do anything to prevent food allergies?”.
We now know introducing peanuts and eggs from around six months of age makes it less likely that an infant will develop an allergy to these foods. The Australasian Society of Clinical Immunology and Allergy introduced guidelines recommending giving common allergy-causing foods including peanut and egg in the first year of life in 2016.
Our research has shown this advice had excellent uptake and may have slowed the rise in food allergies in Australia. There was no increase in peanut allergies between 2007–11 to 2018–19.
Introducing other common allergy-causing foods in the first year of life may also be helpful, although the evidence for this is not as strong compared with peanuts and eggs.
Giving kids peanuts early can reduce the risk of a peanut allergy. Madame-Moustache/Shutterstock What next?
Unfortunately, some infants will develop food allergies even when the relevant foods are introduced in the first year of life. Managing food allergies can be a significant burden for children and families.
Several Australian trials are currently underway testing new strategies to prevent food allergies. A large trial, soon to be completed, is testing whether vitamin D supplements in infants reduce the risk of food allergies.
Another trial is testing whether the amount of eggs and peanuts a mother eats during pregnancy and breastfeeding has an influence on whether or not her baby will develop food allergies.
For most people with food allergies, avoidance of their known allergens remains the standard of care. Oral immunotherapy, which involves gradually increasing amounts of food allergen given under medical supervision, is beginning to be offered in some facilities around Australia. However, current oral immunotherapy methods have potential side effects (including allergic reactions), can involve high time commitment and cost, and don’t cure food allergies.
There is hope on the horizon for new food allergy treatments. Multiple clinical trials are underway around Australia aiming to develop safer and more effective treatments for people with food allergies.

California Is Investing $500M in Therapy Apps for Youth. Advocates Fear It Won’t Pay Off.
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.
With little pomp, California launched two apps at the start of the year offering free behavioral health services to youths to help them cope with everything from living with anxiety to body acceptance.
Through their phones, young people and some caregivers can meet BrightLife Kids and Soluna coaches, some who specialize in peer support or substance use disorders, for roughly 30-minute virtual counseling sessions that are best suited to those with more mild needs, typically those without a clinical diagnosis. The apps also feature self-directed activities, such as white noise sessions, guided breathing, and videos of ocean waves to help users relax.
“We believe they’re going to have not just great impact, but wide impact across California, especially in places where maybe it’s not so easy to find an in-person behavioral health visit or the kind of coaching and supports that parents and young people need,” said Gov. Gavin Newsom’s health secretary, Mark Ghaly, during the Jan. 16 announcement.
The apps represent one of the Democratic governor’s major forays into health technology and come with four-year contracts valued at $498 million. California is believed to be the first state to offer a mental health app with free coaching to all young residents, according to the Department of Health Care Services, which operates the program.
However, the rollout has been slow. Only about 15,000 of the state’s 12.6 million children and young adults have signed up for the apps, school counselors say they’ve never heard of them, and one of the companies isn’t making its app available on Android phones until summer.
Advocates for youth question the wisdom of investing taxpayer dollars in two private companies. Social workers are concerned the companies’ coaches won’t properly identify youths who need referrals for clinical care. And the spending is drawing lawmaker scrutiny amid a state deficit pegged at as much as $73 billion.
An App for That
Newsom’s administration says the apps fill a need for young Californians and their families to access professional telehealth for free, in multiple languages, and outside of standard 9-to-5 hours. It’s part of Newsom’s sweeping $4.7 billion master plan for kids’ mental health, which was introduced in 2022 to increase access to mental health and substance use support services. In addition to launching virtual tools such as the teletherapy apps, the initiative is working to expand workforce capacity, especially in underserved areas.
“The reality is that we are rarely 6 feet away from our devices,” said Sohil Sud, director of Newsom’s Children and Youth Behavioral Health Initiative. “The question is how we can leverage technology as a resource for all California youth and families, not in place of, but in addition to, other behavioral health services that are being developed and expanded.”
The virtual platforms come amid rising depression and suicide rates among youth and a shortage of mental health providers. Nearly half of California youths from the ages of 12 to 17 report having recently struggled with mental health issues, with nearly a third experiencing serious psychological distress, according to a 2021 study by the UCLA Center for Health Policy Research. These rates are even higher for multiracial youths and those from low-income families.
But those supporting youth mental health at the local level question whether the apps will move the needle on climbing depression and suicide rates.
“It’s fair to applaud the state of California for aggressively seeking new tools,” said Alex Briscoe of California Children’s Trust, a statewide initiative that, along with more than 100 local partners, works to improve the social and emotional health of children. “We just don’t see it as fundamental. And we don’t believe the youth mental health crisis will be solved by technology projects built by a professional class who don’t share the lived experience of marginalized communities.”
The apps, BrightLife Kids and Soluna, are operated by two companies: Brightline, a 5-year-old venture capital-backed startup; and Kooth, a London-based publicly traded company that has experience in the U.K. and has also signed on some schools in Kentucky and Pennsylvania and a health plan in Illinois. In the first five months of Kooth’s Pennsylvania pilot, 6% of students who had access to the app signed up.
Brightline and Kooth represent a growing number of health tech firms seeking to profit in this space. They beat out dozens of other bidders including international consulting companies and other youth telehealth platforms that had already snapped up contracts in California.
Although the service is intended to be free with no insurance requirement, Brightline’s app, BrightLife Kids, is folded into and only accessible through the company’s main app, which asks for insurance information and directs users to paid licensed counseling options alongside the free coaching. After KFF Health News questioned why the free coaching was advertised below paid options, Brightline reordered the page so that, even if a child has high-acuity needs, free coaching shows up first.
The apps take an expansive view of behavioral health, making the tools available to all California youth under age 26 as well as caregivers of babies, toddlers, and children 12 and under. When KFF Health News asked to speak with an app user, Brightline connected a reporter with a mother whose 3-year-old daughter was learning to sleep on her own.
‘It’s Like Crickets’
Despite being months into the launch and having millions in marketing funds, the companies don’t have a definitive rollout timeline. Brightline said it hopes to have deployed teams across the state to present the tools in person by midyear. Kooth said developing a strategy to hit every school would be “the main focus for this calendar year.”
“It’s a big state — 58 counties,” Bob McCullough of Kooth said. “It’ll take us a while to get to all of them.”
So far BrightLife Kids is available only on Apple phones. Brightline said it’s aiming to launch the Android version over the summer.
“Nobody’s really done anything like this at this magnitude, I think, in the U.S. before,” said Naomi Allen, a co-founder and the CEO of Brightline. “We’re very much in the early innings. We’re already learning a lot.”
The contracts, obtained by KFF Health News through a records request, show the companies operating the two apps could earn as much as $498 million through the contract term, which ends in June 2027, months after Newsom is set to leave office. And the state is spending hundreds of millions more on Newsom’s virtual behavioral health strategy. The state said it aims to make the apps available long-term, depending on usage.
The state said 15,000 people signed up in the first three months. When KFF Health News asked how many of those users actively engaged with the app, it declined to say, noting that data would be released this summer.
KFF Health News reached out to nearly a dozen California mental health professionals and youths. None of them were aware of the apps.
“I’m not hearing anything,” said Loretta Whitson, executive director of the California Association of School Counselors. “It’s like crickets.”
Whitson said she doesn’t think the apps are on “anyone’s” radar in schools, and she doesn’t know of any schools that are actively advertising them. Brightline will be presenting its tool to the counselor association in May, but Whitson said the company didn’t reach out to plan the meeting; she did.
Concern Over Referrals
Whitson isn’t comfortable promoting the apps just yet. Although both companies said they have a clinical team on staff to assist, Whitson said she’s concerned that the coaches, who aren’t all licensed therapists, won’t have the training to detect when users need more help and refer them to clinical care.
This sentiment was echoed by other school-based social workers, who also noted the apps’ duplicative nature — in some counties, like Los Angeles, youths can access free virtual counseling sessions through Hazel Health, a for-profit company. Nonprofits, too, have entered this space. For example, Teen Line, a peer-to-peer hotline operated by Southern California-based Didi Hirsch Mental Health Services, is free nationwide.
While the state is also funneling money to the schools as part of Newsom’s master plan, students and school-based mental health professionals voiced confusion at the large app investment when, in many school districts, few in-person counseling roles exist, and in some cases are dwindling.
Kelly Merchant, a student at College of the Desert in Palm Desert, noted that it can be hard to access in-person therapy at her school. She believes the community college, which has about 15,000 students, has only one full-time counselor and one part-time bilingual counselor. She and several students interviewed by KFF Health News said they appreciated having engaging content on their phone and the ability to speak to a coach, but all said they’d prefer in-person therapy.
“There are a lot of people who are seeking therapy, and people close to me that I know. But their insurances are taking forever, and they’re on the waitlist,” Merchant said. “And, like, you’re seeing all these people struggle.”
Fiscal conservatives question whether the money could be spent more effectively, like to bolster county efforts and existing youth behavioral health programs.
Republican state Sen. Roger Niello, vice chair of the Senate Budget and Fiscal Review Committee, noted that California is forecasted to face deficits for the next three years, and taxpayer watchdogs worry the apps might cost even more in the long run.
“What starts as a small financial commitment can become uncontrollable expenses down the road,” said Susan Shelley of the Howard Jarvis Taxpayers Association.
