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.
A recent UK-based survey found that…
- while nearly half of adults say dementia is the disease they fear most,
- only a third of those thought you could do anything to avoid it, and
- just 1% could name the 7 known risk factors.
Quick test
Can you name the 7 known risk factors?
Please take a moment to actually try (this kind of mental stimulation is good in any case), and count them out on your fingers (or write them down), and then…
Answer (no peeking if you haven’t listed them yet)
The 7 known risk factors are:
*drumroll please*
- Smoking
- High blood pressure
- Diabetes
- Obesity
- Depression
- Lack of mental stimulation
- Lack of physical activity
How many did you get? If you got them all, well done. If not, then well, now you know, so that’s good too.

Dr. Greger’s Daily Dozen
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.
Give Us This Day Our Daily Dozen
This is Dr. Michael Greger. He’s a physician-turned-author-educator, and we’ve featured him and his work occasionally over the past year or so:
- Brain Food? The Eyes Have It! ← this is about dark leafy greens, lutein, & avoiding Alzheimer’s
- Twenty-One, No Wait, Twenty Tweaks For Better Health ← he says 21, but we say one of them is very skippable. Check it out and decide what you think!
- Dr. Greger’s Anti-Aging Eight ← his top well-evidenced interventions specifically for slowing aging
But what we’ve not covered, astonishingly, is one of the things for which he’s most famous, which is…
Dr. Greger’s Daily Dozen
Based on the research in the very information-dense tome that his his magnum opus How Not To Die (while it doesn’t confer immortality, it does help avoid the most common causes of death), Dr. Greger recommends that we take care to enjoy each of the following things per day:
Beans
- Servings: 3 per day
- Examples: ½ cup cooked beans, ¼ cup hummus
Greens
- Servings: 2 per day
- Examples: 1 cup raw, ½ cup cooked
Cruciferous vegetables
- Servings: 1 per day
- Examples: ½ cup chopped, 1 tablespoon horseradish
Other vegetables
- Servings: 2 per day
- Examples: ½ cup non-leafy vegetables
Whole grains
- Servings: 3 per day
- Examples: ½ cup hot cereal, 1 slice of bread
Berries
- Servings: 1 per day
- Examples: ½ cup fresh or frozen, ¼ cup dried
Other fruits
- Servings: 3 per day
- Examples: 1 medium fruit, ¼ cup dried fruit
Flaxseed
- Servings: 1 per day
- Examples: 1 tablespoon ground
Nuts & (other) seeds
- Servings: 1 per day
- Examples: ¼ cup nuts, 2 tablespoons nut butter
Herbs & spices
- Servings: 1 per day
- Examples: ¼ teaspoon turmeric
Hydrating drinks
- Servings: 60 oz per day
- Examples: Water, green tea, hibiscus tea
Exercise
- Servings: Once per day
- Examples: 90 minutes moderate or 40 minutes vigorous
Superficially it seems an interesting choice to, after listing 11 foods and drinks, have the 12th item as exercise but not add a 13th one of sleep—but perhaps he quite reasonably expects that people get a dose of sleep with more consistency than people get a dose of exercise. After all, exercise is mostly optional, whereas if we try to skip sleep for too long, our body will force the matter for us.
Further 10almonds notes:
- We’d consider chia superior to flax, but you do you. Flax is a fine choice also.
- We recommend trying to get each of these top 5 most health-giving spices in daily if you can.
Enjoy!

Can Home Tests Replace Check-Ups?
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.
It’s Q&A Day at 10almonds!
Have a question or a request? You can always hit “reply” to any of our emails, or use the feedback widget at the bottom!
In cases where we’ve already covered something, we might link to what we wrote before, but will always be happy to revisit any of our topics again in the future too—there’s always more to say!
As ever: if the question/request can be answered briefly, we’ll do it here in our Q&A Thursday edition. If not, we’ll make a main feature of it shortly afterwards!
So, no question/request too big or small
❝I recently hit 65 and try to get regular check-ups, but do you think home testing can be as reliable as a doctor visit? I try to keep as informed as I can and am a big believer in taking responsibility for my own health if I can, but I don’t want to miss something important either. Best as a supplemental thing, perhaps?❞
Depends what’s being tested! And your level of technical knowledge, though there’s always something to be said for ongoing learning.
- If you’re talking blood tests, urine tests, etc per at-home test kits that get sent off to a lab, then provided they’re well-sourced (and executed correctly by you), they should be as accurate as what a doctor will give, since they are basically doing the same thing (taking a sample and sending it off to a lab).
- If you’re talking about checking for lumps etc, then a dual approach is best: check yourself at home as often as you feel is reasonable (with once per month being advised at a minimum, especially if you’re aware of an extra risk factor for you) and check-ups with the doctor per their recommendations.
- If you’re talking about general vitals (blood pressure, heart rate, heart rate variability, VO₂ max, etc), then provided you have a reliable way of testing them, then doing them very frequently at home, to get the best “big picture” view. In contrast, getting them done once a year at your doctor’s could result in a misleading result, if you just ate something different that day or had a stressful morning, for example.

The Fruit That Can Specifically Reduce Belly Fat
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.
Gambooge: Game-Changer Or Gamble?
The gambooge, also called the gummi-gutta, whence its botanical name Garcinia gummi-gutta (formerly Gardinia cambogia), is also known as the Malabar tamarind, and it even got an English name, the brindle berry.
It’s a fruit that looks like a small pale yellow pumpkin in shape, but it grows on trees and has a taste so sour, that it’s usually used only in cooking, and not eaten raw
which makes this writer really want to try it raw now.Its active phytochemical compound hydroxycitric acid (HCA) rose to popularity as a supplement in the US based on a paid recommendation from Dr. Oz, and then became a controversy as supplements associated with it, were in turn associated with hepatotoxicity (more on this in the “Is it safe?” section below).
What do people use it for?
Simply put: it’s a weight loss supplement.
Less simply put: least interestingly, it’s a mild appetite suppressant:
Safety and mechanism of appetite suppression by a novel hydroxycitric acid extract (HCA-SX) ← this talks more about the biochemistry, but isn’t a human study. Human studies have been small and with mixed results. It seems likely that (as in the rat studies discussed above) the mechanism of action is largely about increasing serotonin, which itself is a well-established appetite suppressant. Therefore, the results will depend somewhat on a person’s brain’s serotonergic system.
We’ll revisit that later, but first let’s look at…
Even less simply put: its other mechanism of action is much more interesting; it actually blocks the production of fat (especially: visceral fat) in the body, by inhibiting citrate lyase, which enzyme plays a significant role in fat production:
Effects of (−)-hydroxycitrate on net fat synthesis as de novo lipogenesis
More illustratively, here’s another study, which found:
❝G cambogia reduced abdominal fat accumulation in subjects, regardless of sex, who had the visceral fat accumulation type of obesity. No rebound effect was observed.
It is therefore expected that G cambogia may be useful for the prevention and reduction of accumulation of visceral fat. ❞
~ Dr. Norihiro Shigematsu et al.
As to why this is particularly important, and far more important than mere fat loss in general, see our previous main feature:
Visceral Belly Fat (And How To Lose It)
Is it safe?
It has shown a good safety profile up to large doses (2.8g/day):
Evaluation of the safety and efficacy of hydroxycitric acid or Garcinia cambogia extracts in humans
There have been some fears about hepatotoxicity, but they appear to be unfounded, and based on products that did not, in fact, contain HCA (and were merely sold by a company that used a similar name in their marketing):
No evidence demonstrating hepatotoxicity associated with hydroxycitric acid
However, as it has a serotoninergic effect, it could cause problems for anyone at risk of serotonin syndrome, which means caution is advisable if you are taking SSRIs (which reduce the rate at which the brain can scrub serotonin, with the usually laudable goal of having more serotonin in the brain—but it is possible to have too much of a good thing, and serotonin syndrome isn’t fun).
As ever, do check with your pharmacist and/or doctor, to be sure, since they can advise with regard to your specific situation and any medications you may be taking.

Why Lung Cancer Is On The Rise In Women Who’ve Never Smoked
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.
It’s easy to assume that if you’ve never smoked, lung cancer is just not a risk for you, unless you got very unlucky with an asbestos-laden environment or such.
And yes, smoking is indeed the most overwhelmingly strong risk factor:
❝It is estimated that cigarette smoking explains almost 90% of lung cancer risk in men and 70 to 80% in women❞
Which is a lot (and we’ll address that discrepancy by sex shortly), but meanwhile first let’s mention:
❝Compared with non-smokers, smokers have as much as a 30-fold increased risk of developing cancer.
31% and 26% of all cancer deaths in men and women, respectively, result from lung cancer in the United States.
Overall 5-year survival is only 15%, and 1-year survival is approximately 42%.
In total, lung cancer is responsible for more deaths than prostate, colon, pancreas, and breast cancers combined❞
Source: Smoking and Lung Cancer
Sobering statistics for any smoker, certainly.
But, “smoking is bad for the health” is not the breaking news of the century, so we’ll look now at the other risk factors.
Before we do though, let’s just drop this previous main feature of ours for anyone who does smoke or perhaps who has a loved one who smokes:
Which Addiction-Quitting Methods Work Best? ← it’s not specific just to smoking, but it does cover such also
So, Why the extra risk for women, even if we don’t smoke?
Let’s reframe that first statistic we gave, now presenting the same information differently:
Women who do not smoke are 2–3x more likely to get lung cancer than men who do not smoke.
So… why?
There are three main reasons:
Genetic risks
Cancer often arises from genetic mutations. In the case of lung cancer, genes such as ALK, ROS1, TP53, KRAS, and EGFR are implicated, and some of those are much more likely to mutate in women than in men.
In some cases, it’s because if you have XX chromosomes (as most women do), there are genes you have redundant copies of that people with XY chromosomes don’t. Other less common karyotypes, such as XXY, probably carry higher risks, but that’s just a hypothesis we’re making based on “more copies of a gene = more chances for it to mutate”.
See also: Frequency and Distinctive Spectrum of KRAS Mutations in Never Smokers with Lung Adenocarcinoma
In other cases, it’s because estrogen interacts with the gene mutations, making lung cancer more likely to develop in women over time:
Hormonal risks (but not what you might think)
When something affects women more, it’s easy to blame hormones, but, as researchers have concluded…
❝A reduced lung cancer risk was found for OC and HRT ever users. Both oestrogen only and oestrogen+progestin HRT were associated with decreased risk. No dose-response relationship was observed with years of OC/HRT use. The greatest risk reduction was seen for squamous cell carcinoma in OC users and in both adenocarcinoma and small cell carcinoma in HRT users.❞
OC = oral contraceptive
HRT = hormone replacement therapyNote: we snipped out the statistical calculations for readability and brevity, so if you are interested in those, check out the paper below:
Meanwhile, another research review of 22 studies with nearly a million participants found:
❝Current or ever HRT use is partly correlated with the decreased incidence of lung cancer in women.
Concerns about the incidence of lung cancer can be reduced when perimenopausal and postmenopausal women use current HRT to reduce menopausal symptoms.❞
So, the problem seems to at least a lot of the time be not estrogen (notwithstanding what we mentioned previously about mutations—sometimes a thing can have both pros and cons), but rather, untreated menopause being the higher risk factor.
This is very reminiscent of what we talked about in one of our main features about Alzheimer’s disease:
Alzheimer’s Sex Differences May Not Be What They Appear ← Women get Alzheimer’s at nearly 2x the rate than men do, and deteriorate more rapidly after onset, too.
Chronic inflammation
For reasons that have not been tied to genetics or hormones*, women suffer from autoimmune diseases at much higher rates than men.
*presumably it is at least one or the other, because there aren’t a lot of other options that seem plausible, but (as with many “this thing mainly affects women” maladies), science hasn’t yet determined the cause.
Because cancer is in part a disease of immune dysfunction (cells fail to kill cells they should be killing), having an autoimmune disease, or indeed chronic inflammation in general, will result in a higher risk of cancer.
For general theory, see: Cancer and Autoimmune Diseases: A Tale of Two Immunological Opposites?
For specifics, see: Non–Small Cell Lung Cancer: Role of the Immune System and Potential for Immunotherapy
And this one is the most likely explanation of why lung cancer in women who’ve never smoked is on the rise—it’s because chronic inflammation in women is on the rise. While people regardless of gender are getting chronic inflammation at increased rates nowadays (probably due in large part to the rise of ultra-processed food, as well as the higher stress of modern life, but again, we’re hypothesizing), if all other factors are equal, women will still get it more than men.
However!
Like the consideration of HRT’s protective effects (and unlike the genetic factors), this is one we can do something about.

Orange vs Starfruit – 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 orange to starfruit, we picked the orange.
Why?
In terms of macros, there’s little between them; oranges are slightly higher in carbs for the same fiber and protein, but if you’re eating whole fruit, it really doesn’t make a difference. So, we call this round a tie.
In the category of vitamins, oranges have rather more of vitamins A, B1, B2, B6, B9, C, and E, while starfruit has slightly more of vitamins B3 and B5, yielding a 7:2 win to oranges here.
Looking at minerals, oranges have more calcium, iron, phosphorus, and potassium, while starfruit has more copper, manganese, selenium, and zinc, for a 4:4 tie this time.
Adding up the sections makes for a modest overall win for oranges, but by all means enjoy either or both, as diversity is best!

Navigating the health-care system is not easy, but you’re not alone.
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.
Hello, dear reader!
This is my first column for Healthy Debate as a Patient Navigator. This column will be devoted to providing patients with information to help them through their journey with the health-care system and answering your questions.
Here’s a bit about me: I have been a patient partner at The Ottawa Hospital and Ottawa Hospital Research Institute since 2017, and have joined a variety of governance boards that work on patient and caregiver engagement such as the Patient Advisors Network, the Ontario Health East Region Patient and Family Advisory Council and the Equity in Health Systems Lab.
My journey as a patient partner started much before 2017 though. When I was a teenager, I was diagnosed with a cholesteatoma, a rare and chronic disease that causes the development of fatty tumors in the middle ear. I have had multiple surgeries to try to fix it but will need regular follow-ups to monitor whether the tumor returns. Because of this, I also live with an invisible disability since I have essentially become functionally deaf in one ear and often rely on a hearing aid when I navigate the world.
Having undergone three surgeries in my adolescent years, it was my experience undergoing surgery for an acute hand and wrist injury following a jet ski accident as an adult that was the catalyst for my decision to become a patient partner. There was an intriguing contrast between how I was cared for at two different health-care institutions, my age being the deciding factor at which hospital I went to (a children’s hospital or an adult one).
The most memorable example was how, as a teenager or child, you were never left alone before surgery, and nurses and staff took all the time necessary to comfort me and answer my (and my family’s) questions. I also remember how right before putting me to sleep, the whole staff initiated a surgical pause and introduced themselves and explained to me what their role was during my surgery.
None of that happened as an adult. I was left in a hallway while the operating theater was prepared, anxious and alone with staff walking by not even batting an eye. My questions felt like an annoyance to the care team; as soon as I was wheeled onto the operating room table, the anesthetist quickly put me to sleep. I didn’t even have the time to see who else was there.
Now don’t get me wrong: I am incredibly appreciative with the quality of care I received, but it was the everyday interactions with the care teams that I felt could be improved. And so, while I was recovering from that surgery, I looked for a way to help other patients and the hospital improve its care. I discovered the hospital’s patient engagement program, applied, and the rest is history!
Since then, I have worked on a host of patient-centered policy and research projects and fervently advocate that surgical teams adopt a more compassionate approach with patients before and after surgery.
I’d be happy to talk a bit more about my journey if you ask, but with that out of the way … Welcome to our first patient navigator column about patient engagement.
Conceptualizing the continuum of Patient Engagement
In the context of Canadian health care, patient engagement is a multifaceted concept that involves active collaboration between patients, caregivers, health-care providers and researchers. It involves patients and caregivers as active contributors in decision-making processes, health-care services and medical research. Though the concept is not new, the paradigm shift toward patient engagement in Canada started around 2010.
I like to conceptualize the different levels of patient engagement as a measure of the strength of the relationship between patients and their interlocutors – whether it’s a healthcare provider, administrator or researcher – charted against the duration of the engagement or the scope of input required from the patient.
Defining different levels of Patient Engagement
Following the continuum, let’s begin by defining different levels of patient engagement. Bear in mind that these definitions can vary from one organization to another but are useful in generally labelling the level of patient engagement a project has achieved (or wishes to achieve).
Patient involvement: If the strength of the relationship between patients and their interlocutors is minimal and not time consuming or too onerous, then perhaps it can be categorized as patient involvement. This applies to many instances of transactional engagement.
Patient advisory/consulting: Right in the middle of our continuum, patients can find themselves engaging in patient advisory or consulting work, where projects are limited in scope and duration or complexity, and the relationship is not as profound as a partnership.
Patient partnership: The stronger the relationship is between the patient and their interlocutor, and the longer the engagement activity lasts or how much input the patient is providing, the more this situation can be categorized as patient partnership. It is the inverse of patient involvement.
Examples of the different levels of Patient Engagement
Let’s pretend you are accompanying a loved one to an appointment to manage a kidney disease, requiring them to undergo dialysis treatment. We’ll use this scenario to exemplify what label could be used to describe the level of engagement.
Patient involvement: In our case, if your loved one – or you – fills out a satisfaction or feedback survey about your experience in the waiting room and all that needed to be done was to hand it back to the clerk or care team, then, at a basic level, you could likely label this interaction as a form of patient involvement. It can also involve open consultations around a design of a new look and feel for a hospital, or the understandability of a survey or communications product. Interactions with the care team, administrators or researchers are minimal and often transactional.
Patient advisory/consulting: If your loved one was asked for more detailed information about survey results over the course of a few meetings, this could represent patient advisory/consulting. This could mean that patients meet with program administrators and care providers and share their insights on how things can be improved. It essentially involves patients providing advice to health-care institutions from the perspective of patients, their family members and caregivers.
Patient advisors or consultants are often appointed by hospitals or academic institutions to offer insights at multiple stages of health-care delivery and research. They can help pilot an initiative based on that feedback or evaluate whether the new solutions are working. Often patient advisors are engaged in smaller-term individual projects and meet with the project team as regularly as required.
Patient partnership: Going above and beyond patient advisory, if patients have built a trusting relationship with their care team or administrators, they could feel comfortable enough to partner with them and initiate a project of their own. This could be for a project in which they study a different form of treatment to improve patient-centered outcomes (like the time it takes to feel “normal” following a session); it could be working together to identify and remove barriers for other patients that need to access that type of care. These projects are not fulfilled overnight, but require a collaborative, longstanding and trusting relationship between patients and health-care providers, administrators or researchers. It ensures that patients, regardless of severity or chronicity of their illness, can meaningfully contribute their experiences to aid in improving patient care, or develop or implement policies, pilots or research projects from start to finish.
It is leveraging that lived and living experience to its full extent and having the patient partner involved as an equal voice in the decision-making process for a project – over many months, usually – that the engagement could be labeled a partnership.
Last words
The point of this column will be to answer or explore issues or questions related to patient engagement, health communications or even provide some thoughts on how to handle a particular situation.
I would be happy to collect your questions and feedback at any time, which will help inform future columns. Just email me at [email protected] or connect with me on social media (Linked In, X / Twitter).
