Our Verdict

When comparing lychees to kumquats, we picked the kumquats.

Why?

In terms of macros, everything is comparable except for fiber, of which kumquats have 5–6x as much fiber, which means a very significant win for kumquats in this category.

When it comes to vitamins, lychees have slightly more of vitamins B3, B6, C, and K, while kumquats have a lot more of vitamins A and B1, and moderately more vitamins B2, B9, E, and choline. A fair win for kumquats here.

In the category of minerals, lychees have a little more copper, phosphorus, and selenium, while kumquats have 11x as much calcium, as well as a 2–3x more iron, magnesium, manganese and zinc. An easy win for kumquats.

Both fruits have great phenolic profiles, being both rich in antioxidants.

All in all, enjoy both, but if you’re going to pick one, kumquats easily win the day!

  • How does the hair-loss drug finasteride work? Can it affect my mental 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.

    For many men the gradual thinning of hair is about more than just their appearance. Finasteride, a drug widely prescribed for the treatment of male pattern baldness has been used effectively for many years for this deeply personal problem.

    Yet, behind its use are growing concerns about its link to the development of depression, anxiety, and even suicidal thoughts.

    There is now critical discussion among both users and health-care professionals about the potential hazards associated with its continued use.

    So how does the drug work? And what does the evidence say about the risk of developing a mental health problem?

    How does finasteride work?

    Finasteride is used to treat androgenetic alopecia, also known as male pattern baldness. It works to regrow hair and prevent the further loss of hair.

    One of the key causes of pattern baldness is the production of a hormone called dihydrotestosterone which the body makes from testosterone. When it binds to the follicles of hairs, it initiates a process called hair follicle miniaturisation. This is where the growth cycle of the hair becomes progressively shorter, resulting in thinner and weaker hair.

    Finasteride works by blocking the enzyme that converts testosterone to dihydrotestosterone. By blocking the enzyme, dihydrotestosterone concentrations can be reduced by around 60–70% for the majority of men.

    Finasteride was first approved in the late 1990s as a prescription-only medicine and is taken as a daily 1 milligram oral tablet. Medications available at a higher 5 mg daily dose are not used for baldness, but as a treatment for non-cancerous prostate enlargement.

    This medication is not indicated for women, even though they can also have this type of hair loss.

    How can it impact your mental health?

    Changes in mental health are not listed as an established side effect in Australian guidance given to health-care professionals.

    Based on clinical trials, the most common effects include:

    • decreased libido
    • erectile dysfunction
    • reduced semen production.

    The guidance also describes an increased risk of prostate cancer and a potential risk for breast cancer. Yes, men can get breast cancer too.

    While initial clinical trials conducted to obtain approval for the drug didn’t demonstrate mental health concerns, monitoring of patients using the drug has since indicated a potential increased risk of depression and suicidal thoughts. But as this is based on patients self-reporting symptoms, according to the guidance there is no definitive link.

    However, in May 2025, the European Medicines Agency safety committee stated suicidal thoughts was a confirmed side effect of finasteride. The European Union also advises patients that finasteride can cause a depressed mood and depression.

    Similarly, in a warning about compounded finasteride, the United States Food and Drug Administration stated in April 2025 that topical formulations of the drug has similar side effects to the oral version. These include depression, anxiety and suicidal thoughts.

    What should you do if it is affecting your mental health?

    If you notice changes in your mental health while taking the drug, try not to handle significant mood changes by yourself. If you’re feeling unusually low, anxious or emotionally unstable, check in with a doctor so they can help you figure out whether finasteride is contributing to your mood and what support you may need.

    If the symptoms are mild, they may suggest pausing finasteride to see whether things improve, or continuing with additional mental health support. If your symptoms are more severe, stopping the medication and getting prompt medical review may be appropriate.

    If you are taking finasteride and are worried about its side effects, it is safe to stop immediately. Most side effects ease once the medication is out of your system, although a small number of people have reported symptoms that persist.

    If you do decide to stop, this will mean that your hormone levels will gradually return to baseline and the hair growth seen with the drug will be lost over time.

    If finasteride is not the right fit for you, there is another evidence-based alternative.

    Topical minoxidil is a first-line treatment that can be used on its own or with other treatments and is available from pharmacies over the counter. It only works while it’s being used and may irritate the scalp, but its effectiveness is well-established and widely recommended.

    While depression and anxiety are associated with minoxidil, the incidence is much lower because of their topical application.

    There is also a medication called dutasteride. However, as it works in a similar way to finasteride, it may also increase your risk of developing mental health problems. So it is best to avoid dutasteride if finasteride is not suitable for you.

  • A Guide to Rational Living – by Drs. Albert Ellis and Robert Harper

    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’ve talked before about the evidence-based benefits of Cognitive Behavioral Therapy (CBT), and this book is indeed about CBT. In fact, it’s in many ways the book that popularized Third Wave CBT—in other words, CBT in its modern form.

    Dr. Ellis’s specific branch of CBT is Rational Emotive Behavior Therapy, (REBT). What this means is using rationality to rewire emotions so that we’re not constantly sabotaging ourselves and our lives.

    This is very much a “for the masses” book and doesn’t assume any prior knowledge of psychology, therapy, or psychotherapy. Or, for that matter, philosophy, since Stoic philosopher Epictetus had a lot to say that influenced Dr. Ellis’s work, too!

    This book has also been described as “a self-help book for people who don’t like self-help books”… and certainly that Stoicism we mentioned does give the work a very different feel than a lot of books on the market.

    The authors kick off with an initial chapter “How far can you go with self-therapy?”, and the answer is: quite far, even if it’s not a panacea. Everything has its limitations, and this book is no exception. On the other hand…

    What the book does offer is a whole stack of tools, resources, and “How to…” chapters. In fact, there are so many “How to…” items in this book that, while it can be read cover-to-cover, it can also be used simply as a dip-in reference guide to refer to in times of need.

    Bottom line: this book is highly recommendable to anyone and everyone, and if you don’t have it on your bookshelf, you should.

  • The Coffee-Cortisol Connection, And Two Ways To Tweak It For 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.

    Health opinions on coffee vary from “it’s an invigorating, healthful drink” to “it will leave you a shaking frazzled wreck”. So, what’s the truth and can we enjoy it healthily? Dr. Alan Mandell weighs in:

    Enjoy it, but watch out!

    Dr. Mandell is speaking only for caffeinated coffee in this video, and to this end, he’s conflating the health effects of coffee and caffeine. A statistically reasonable imprecision, since most people drink coffee with its natural caffeine in, but we’ll make some adjustment to his comments below, to disambiguate which statements are true for coffee generally, and which are true for caffeine:

    • Drinking coffee caffeine first thing in the morning may not be ideal due to dehydration from overnight water loss.
    • Coffee caffeine is a diuretic, which means an increase in urination, thus further dehydrating the body.
    • Coffee contains great antioxidants, which are of course beneficial for the health in general.
    • Cortisol, the body’s stress hormone, is generally at its peak in the morning. This is, in and of itself, good and correct—it’s how we wake up.
    • Coffee caffeine consumption raises cortisol levels even more, leading to increased alertness and physical readiness, but it is possible to have too much of a good thing, and in this case, problems can arise because…
    • Elevated cortisol from early coffee caffeine drinking can build tolerance, leading to the need for more coffee caffeine over time.
    • It’s better, therefore, to defer drinking coffee caffeine until later in the morning when cortisol levels naturally drop.
    • All of this means that drinking coffee caffeine first thing can disrupt the neuroendocrine system, leading to fatigue, depression, and general woe.
    • Hydrate first thing in the morning before consuming coffee caffeine to keep the body balanced and healthy.

    What you can see from this is that coffee and caffeine are not, in fact, interchangeable words, but the basic message is clear and correct: while a little spike of cortisol in the morning is good, natural, and even necessary, a big spike is none of those things, and caffeine can cause a big spike, and since for most people caffeine is easy to build tolerance to, there will indeed consistently be a need for more, worsening the problem.

    In terms of hydration, it’s good to have water (or better yet, herbal tea) on one’s nightstand to drink when one wakes up.

    If coffee is an important morning ritual for you, consider finding a good decaffeinated version for at least your first cup (this writer is partial to Lavazza’s “Dek Intenso”—which is not the same as their main decaf line, by the way, so do hold out for the “Dek Intenso” if you want to try my recommendation).

    Decaffeinated coffee is hydrating and will not cause a cortisol spike (unless for some reason you find coffee as a concept very stressful in which case, yes, the stressor will cause a stress response).

    Anyway, for more on all of this, enjoy:

  • The Weight’s Over – by Sandra Roycroft-Davis

    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.

    Many diet books say “this is not a diet book”, even ones with titles like “The Such-And-Such Diet”. So, how does this one weigh up?

    It is… *drumroll please* not a diet book! It’s entirely about reframing one’s attitude towards various things, including:

    • Numbers on the scale
    • Self-limiting beliefs
    • Cravings
    • Self-esteem
    • Stress
    • Guilt
    • Willpower

    The methodology is in fact very anti-dieting in the restrictive sense of the word, and rather is a call to intuitive eating, mindful eating, and engagement with one’s own values, supporting these things with an extensive array of psychological tools (including, but not limited to, CBT and NLP).

    The style is quite a mix. It’s as motivationally written as you might expect, with lengthy testimonials from happy clients at the end of each chapter. It also has frequent references for claims, although these are mostly for cited statistics, rather than for the actual methods recommended.

    The early pre-chapters before part one were a little wearying to this reviewer; the author is distractingly proud of having an office on Harley Street (a once-prestigious London address famous for illustrious doctors; nowadays it’s merely expensive), and this reviewer was starting to wonder if she could go for more than a page without mentioning it. However, happily that did taper out and most of the rest (aside from the testimonials, which might be considered padding) was valuable content.

    And, we want to be clear: while we’ve criticized the style a bit, the advice itself is actually excellent and is certainly as potentially life-changing as its many annoying testimonials attest.

    Bottom line: if you’re at the point where it seems the main barrier to the weight loss that you want (and the book does assume that weight loss is what you ultimately want, by the way) is yourself, then this book can definitely help you overcome that hurdle.

  • Healthy Living in a Contaminated World – by Dr. Donald Hoernschemeyer

    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’s a lot going on here, as this book tackles very many kinds of common contaminants, from waste products and industrial chemicals (such as from fracking), pesticides that are banned in most places but not the US, smog and soot from coal and oil power, mercury and other heavy metals, dioxins, Teflon and its close relatives, phthalates, BPA, and other things again regulated out of use in many countries but not entirely in the US (which bans them only in some things, like baby bottles), drinking water issues of various kinds, and much more.

    Indeed, there’s a whole chapter on the US and international regulation of toxic substances; the problem is often that on a political level, the same people who are against nebulous “chemicals” are also against environmentalist regulations that would ban them. This is mostly not a political book though, and rather is chiefly a book of chemistry (the author’s field).

    It does also cover the medical maladies associated with various contaminants, while the bulk of the data is on the chemistry side of such things as “elimination times for toxic chemicals”, “amounts of pesticides in fruit and vegetables”, “antibiotics and hormones used in animal agriculture”, and so forth.

    The style is dense, and/but it is clear the author has made an effort to not be too dry. Still, this is not a fun read; it’s depressing in content and the style is more suited to academia. There are appendices containing glossaries and acronym tables, but reading front-to-back, there’s a lot that’s not explained so unless you also are a PhD chemist, chances are you’ll be needing to leaf forwards and backwards a lot.

    Bottom line: this book is not thrilling, but what you don’t know, can kill you.

  • Older Men’s Connections Often Wither When They’re on Their Own

    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.

    At age 66, South Carolina physician Paul Rousseau decided to retire after tending for decades to the suffering of people who were seriously ill or dying. It was a difficult and emotionally fraught transition.

    “I didn’t know what I was going to do, where I was going to go,” he told me, describing a period of crisis that began in 2017.

    Seeking a change of venue, Rousseau moved to the mountains of North Carolina, the start of an extended period of wandering. Soon, a sense of emptiness enveloped him. He had no friends or hobbies — his work as a doctor had been all-consuming. Former colleagues didn’t get in touch, nor did he reach out.

    His wife had passed away after a painful illness a decade earlier. Rousseau was estranged from one adult daughter and in only occasional contact with another. His isolation mounted as his three dogs, his most reliable companions, died.

    Rousseau was completely alone — without friends, family, or a professional identity — and overcome by a sense of loss.

    “I was a somewhat distinguished physician with a 60-page resume,” Rousseau, now 73, wrote in the Journal of the American Geriatrics Society in May. “Now, I’m ‘no one,’ a retired, forgotten old man who dithers away the days.”

    In some ways, older men living alone are disadvantaged compared with older women in similar circumstances. Research shows that men tend to have fewer friends than women and be less inclined to make new friends. Often, they’re reluctant to ask for help.

    “Men have a harder time being connected and reaching out,” said Robert Waldinger, a psychiatrist who directs the Harvard Study of Adult Development, which has traced the arc of hundreds of men’s lives over a span of more than eight decades. The men in the study who fared the worst, Waldinger said, “didn’t have friendships and things they were interested in — and couldn’t find them.” He recommends that men invest in their “social fitness” in addition to their physical fitness to ensure they have satisfying social interactions.

    Slightly more than 1 in every 5 men ages 65 to 74 live alone, according to 2022 Census Bureau data. That rises to nearly 1 in 4 for those 75 or older. Nearly 40% of these men are divorced, 31% are widowed, and 21% never married.

    That’s a significant change from 2000, when only 1 in 6 older men lived by themselves. Longer life spans for men and rising divorce rates are contributing to the trend. It’s difficult to find information about this group — which is dwarfed by the number of women who live alone — because it hasn’t been studied in depth. But psychologists and psychiatrists say these older men can be quite vulnerable.

    When men are widowed, their health and well-being tend to decline more than women’s.

    “Older men have a tendency to ruminate, to get into our heads with worries and fears and to feel more lonely and isolated,” said Jed Diamond, 80, a therapist and the author of “Surviving Male Menopause” and “The Irritable Male Syndrome.”

    Add in the decline of civic institutions where men used to congregate — think of the Elks or the Shriners — and older men’s reduced ability to participate in athletic activities, and the result is a lack of stimulation and the loss of a sense of belonging.

    Depression can ensue, fueling excessive alcohol use, accidents, or, in the most extreme cases, suicide. Of all age groups in the United States, men over age 75 have the highest suicide rate, by far.

    For this column, I spoke at length to several older men who live alone. All but two (who’d been divorced) were widowed. Their experiences don’t represent all men who live alone. But still, they’re revealing.

    The first person I called was Art Koff, 88, of Chicago, a longtime marketing executive I’d known for several years. When I reached out in January, I learned that Koff’s wife, Norma, had died the year before, leaving him hobbled by grief. Uninterested in eating and beset by unremitting loneliness, Koff lost 45 pounds.

    “I’ve had a long and wonderful life, and I have lots of family and lots of friends who are terrific,” Koff told me. But now, he said, “nothing is of interest to me any longer.”

    “I’m not happy living this life,” he said.

    Nine days later, I learned that Koff had died. His nephew, Alexander Koff, said he had passed out and was gone within a day. The death certificate cited “end stage protein calorie malnutrition” as the cause.

    The transition from being coupled to being single can be profoundly disorienting for older men. Lodovico Balducci, 80, was married to his wife, Claudia, for 52 years before she died in October 2023. Balducci, a renowned physician known as the “patriarch of geriatric oncology,” wrote about his emotional reaction in the Journal of the American Geriatrics Society, likening Claudia’s death to an “amputation.”

    “I find myself talking to her all the time, most of the time in my head,” Balducci told me in a phone conversation. When I asked him whom he confides in, he admitted, “Maybe I don’t have any close friends.”

    Disoriented and disorganized since Claudia died, he said his “anxiety has exploded.”

    We spoke in late February. Two weeks later, Balducci moved from Tampa to New Orleans, to be near his son and daughter-in-law and their two teenagers.

    “I am planning to help as much as possible with my grandchildren,” he said. “Life has to go on.”

    Verne Ostrander, a carpenter in the small town of Willits, California, about 140 miles north of San Francisco, was reflective when I spoke with him, also in late February. His second wife, Cindy Morninglight, died four years ago after a long battle with cancer.

    “Here I am, almost 80 years old — alone,” Ostrander said. “Who would have guessed?”

    When Ostrander isn’t painting watercolors, composing music, or playing guitar, “I fall into this lonely state, and I cry quite a bit,” he told me. “I don’t ignore those feelings. I let myself feel them. It’s like therapy.”

    Ostrander has lived in Willits for nearly 50 years and belongs to a men’s group and a couples’ group that’s been meeting for 20 years. He’s in remarkably good health and in close touch with his three adult children, who live within easy driving distance.

    “The hard part of living alone is missing Cindy,” he told me. “The good part is the freedom to do whatever I want. My goal is to live another 20 to 30 years and become a better artist and get to know my kids when they get older.”

    The Rev. Johnny Walker, 76, lives in a low-income apartment building in a financially challenged neighborhood on Chicago’s West Side. Twice divorced, he’s been on his own for five years. He, too, has close family connections. At least one of his several children and grandchildren checks in on him every day.

    Walker says he had a life-changing religious conversion in 1993. Since then, he has depended on his faith and his church for a sense of meaning and community.

    “It’s not hard being alone,” Walker said when I asked whether he was lonely. “I accept Christ in my life, and he said that he would never leave us or forsake us. When I wake up in the morning, that’s a new blessing. I just thank God that he has brought me this far.”

    Waldinger recommended that men “make an effort every day to be in touch with people. Find what you love — golf, gardening, birdwatching, pickleball, working on a political campaign — and pursue it,” he said. “Put yourself in a situation where you’re going to see the same people over and over again. Because that’s the most natural way conversations get struck up and friendships start to develop.”

    Rousseau, the retired South Carolina doctor, said he doesn’t think about the future much. After feeling lost for several years, he moved across the country to Jackson, Wyoming, in the summer of 2023. He embraced solitude, choosing a remarkably isolated spot to live — a 150-square-foot cabin with no running water and no bathroom, surrounded by 25,000 undeveloped acres of public and privately owned land.

    “Yes, I’m still lonely, but the nature and the beauty here totally changed me and focused me on what’s really important,” he told me, describing a feeling of redemption in his solitude.

    Rousseau realizes that the death of his parents and a very close friend in his childhood left him with a sense of loss that he kept at bay for most of his life. Now, he said, rather than denying his vulnerability, he’s trying to live with it. “There’s only so long you can put off dealing with all the things you’re trying to escape from.”

    It’s not the life he envisioned, but it’s one that fits him, Rousseau said. He stays busy with volunteer activities — cleaning tanks and running tours at Jackson’s fish hatchery, serving as a part-time park ranger, and maintaining trails in nearby national forests. Those activities put him in touch with other people, mostly strangers, only intermittently.

    What will happen to him when this way of living is no longer possible?

    “I wish I had an answer, but I don’t,” Rousseau said. “I don’t see my daughters taking care of me. As far as someone else, I don’t think there’s anyone else who’s going to help me.”
