Glutathione’s Benefits: The Usual And The Unique

Glutathione is a powerful antioxidant that does all the things we might reasonably expect an antioxidant to do, plus some beneficial quirks of its own.

We do make glutathione in our bodies, but we can also get it from our diet, and of course, we can also supplement it.

What foods is it in?

It’s in a lot of foods, but some top examples include:

  • turmeric
  • avocado
  • asparagus
  • almonds
  • cruciferous vegetables
  • watermelon
  • garlic

For a fuller list and discussion, see:

Glutathione for Food and Health Applications with Emphasis on Extraction, Identification, and Quantification Methods: A Review

What does it do?

Let’s start with the obvious; as with most things that are antioxidant, it is also anti-inflammatory. Increasing or decreasing glutathione levels is associated with decreased or increased inflammation, respectively. For example:

Glutathione S-transferase theta 1 protects against colitis through goblet cell differentiation via interleukin-22

It being anti-inflammatory also means it can be beneficial in calming autoimmune disorders:

Glutathione: a key player in autoimmunity

And to complete the triad of “those three things that generally go together”, yes, this means it also has anticancer potential, but watch out!

❝Although in healthy cells [glutathione] is crucial for the removal and detoxification of carcinogens, elevated [glutathione] levels in tumor cells are associated with tumor progression and increased resistance to chemotherapeutic drugs❞

~ Dr. Miroslava Cuperlovic-Culf et al.

Read in full: Role of Glutathione in Cancer: From Mechanisms to Therapies

So in other words, when it comes to cancer risk management, glutathione is a great preventative, but the opposite of a cure.

What were those “beneficial quirks of its own”?

They are mainly twofold, and the first is that it improves insulin sensitivity. There are many studies showing this, but here’s a recent one from earlier this year:

The Role of Glutathione and Its Precursors in Type 2 Diabetes

The other main “beneficial quirk of its own” is that it helps prevent and/or reverse non-alcoholic fatty liver disease, as in this study from last year:

Glutathione: Pharmacological aspects and implications for clinical use in non-alcoholic fatty liver disease

Because of glutathione’s presence in nuts, fruits, and vegetables, this makes it a great thing to work in tandem with a dietary approach to preventing/reversing NAFLD, by the way:

How To Unfatty A Fatty Liver

Anything else?

It’s being investigated as a potential treatment for Parkinson’s disease symptoms, but the science is young for this one, so there is no definitive recommendation yet in this case. If you’re interested in that, though, do check out the current state of the science at:

Potential use of glutathione as a treatment for Parkinson’s disease

Is it safe?

While there is no 100% blanket statement of safety that can ever be made about anything (even water can kill people, and oxygen ultimately kills everyone that something else doesn’t get first), glutathione has one of the safest general safety profiles possible, with the exception we noted earlier (if you have cancer, it is probably better to skip this one unless an oncologist or similar advises you otherwise).

As ever, do speak with your doctor/pharmacist to be sure in any case, though!

  • Stop Trying To Lose Weight (And Do This Instead)

    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.

    “Lose weight” is a common goal of many people, and it’s especially a common goal handed down from medical authority figures, often as a manner of “kicking the can down the road” with regard to the doctor actually having to do some work. “Lose 20 pounds and then we’ll talk”, etc.

    The thing is, it’s often not a very good or helpful goal… Even if it would be healthy for a given person to lose weight. Instead, biochemist Jessie Inchauspé argues, one should set a directly health-giving goal instead, and let any weight loss, if the body agrees it is appropriate, be a by-product of that

    She recommends focusing on metabolic health, specifically, her own specialism is blood glucose maintenance. This is something that diabetics deal with (to one degree or another) every day, but it’s something whose importance should not be underestimated for non-diabetics too.

    Keep our blood sugar levels healthy, she says, and a lot of the rest of good health will fall into place by itself—precisely because we’re not constantly sabotaging our body (first the pancreas and liver, then the rest of the body like dominoes).

    To that end, she offers a multitude of “hacks” that really work.

    Her magnum opus, “Glucose Revolution“, explains the science in great detail and does it very well! Not to be mistaken for her shorter, simpler, and entirely pragmatic “do this, then this”-style book, “The Glucose Goddess Method”, which is also great, but doesn’t go into the science more than absolutely necessary; it’s more for the “I’ll trust you; just tell me what I need to know” crowd.

    In her own words:

  • What you need to know about PCOS

    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.

    In 2008, microbiologist Sasha Ottey saw her OB-GYN because she had missed some periods. The doctor ran blood tests and gave her an ultrasound, diagnosing her with polycystic ovary syndrome (PCOS). She also told her not to worry, referred her to an endocrinologist (a doctor who specializes in hormones), and told her to come back when she wanted to get pregnant. 

    “I found [that] quite dismissive because that was my reason for presenting to her,” Ottey tells PGN. “I felt that she was missing an opportunity to educate me on PCOS, and that was just not an accurate message: Missing periods can lead to other serious, life-threatening health conditions.” 

    During the consultation with the endocrinologist, Ottey was told to lose weight and come back in six months. “Again, I felt dismissed and left up to my own devices to understand this condition and how to manage it,” she says. 

    Following that experience, Ottey began researching and found that thousands of people around the world had similar experiences with their PCOS diagnoses, which led her to start and lead the advocacy and support organization PCOS Challenge

    PCOS is the most common hormonal condition affecting people with ovaries of reproductive age. In the United States, one in 10 women of childbearing age have the condition, which affects the endocrine and reproductive systems and is a common cause of infertility. Yet, the condition is significantly underdiagnosed—especially among people of color—and under-researched

    Read on to find out more about PCOS, what symptoms to look out for, what treatments are available, and useful resources. 

    What is PCOS, and what are its most common symptoms? 

    PCOS is a chronic hormonal condition that affects how the ovaries work. A hormonal imbalance causes people with PCOS to have too much testosterone, the male sex hormone, which can make their periods irregular and cause hirsutism (extra hair), explains Dr. Melanie Cree, associate professor at the University of Colorado School of Medicine and director of the Multi-Disciplinary PCOS clinic at Children’s Hospital Colorado. 

    This means that people can have excess facial or body hair or experience hair loss. 

    PCOS also impacts the relationship between insulin—the hormone released when we eat—and testosterone. 

    “In women with PCOS, it seems like their ovaries are sensitive to insulin, and so when their ovaries see insulin, [they] make extra testosterone,” Cree adds. “So things that affect insulin levels [like sugary drinks] can affect testosterone levels.”

    Other common symptoms associated with PCOS include:

    • Acne
    • Thinning hair
    • Skin tags or excess skin in the armpits or neck 
    • Ovaries with many cysts
    • Infertility
    • Anxiety, depression, and other mental health conditions
    • Sleep apnea, a condition where breathing stops and restarts while sleeping

    What causes PCOS?

    The cause is still unknown, but researchers have found that the condition is genetic and can be inherited. Experts have found that exposure to harmful chemicals like PFAs, which can be present in drinking water, and BPA, commonly used in plastics, can also increase the risk for PCOS

    Studies have shown that “BPA can change how the endocrine system develops in a developing fetus … and that women with PCOS tend to also have more BPA in their bodies,” adds Dr. Felice Gersh, an OB-GYN and founder and director of the Integrative Medical Group of Irvine, which treats patients with PCOS. 

    How is PCOS diagnosed?

    PCOS is diagnosed through a physical exam; a conversation with your health care provider about your symptoms and medical history; a blood test to measure your hormone levels; and, in some cases, an ultrasound to see your ovaries. 

    PCOS is what’s known as a “diagnosis of exclusion,” Ottey says, meaning that the provider must rule out other conditions, such as thyroid disease, before diagnosing it. 

    Why isn’t more known about PCOS?

    Research on PCOS has been scarce, underfunded, and narrowly focused. Research on the condition has largely focused on the reproductive system, Ottey says, even though it also affects many aspects of a person’s life, including their mental health, appearance, metabolism, and weight. 

    “There is the point of getting pregnant, and the struggle to get pregnant for so many people,” Ottey adds. “[And] once that happens, [the condition] also impacts your ability to carry a healthy pregnancy, to have healthy babies. But outside of that, your metabolic health is at risk from having PCOS, your mental health is at risk, [and] overall health and quality of life, they’re all impacted by PCOS.” 

    People with PCOS are more likely to develop other serious health issues, like high blood pressure, heart problems, high cholesterol, uterine cancer, and diabetes. Cree says that teenagers with PCOS and obesity have “an 18-fold higher risk of type 2 diabetes” in their teens and that teenagers who get type 2 diabetes are starting to die in their late 20s and early 30s. 

    What are some treatments for PCOS?

    There is still no single medication approved by the Food and Drug Administration specifically for PCOS, though advocacy groups like PCOS Challenge are working with the agency to incorporate patient experiences and testimonials into a possible future treatment. Treatment depends on what symptoms you experience and what your main concerns are.

    For now, treatment options include the following:

    • Birth control: Your provider may prescribe birth control pills to lower testosterone levels and regulate your menstrual cycle. 
    • Lifestyle changes: Because testosterone can affect insulin levels, Cree explains that regardless of a patient’s weight, a diet with lower simple carbohydrates (such as candy, sugar, sweets, juices, sodas, and coffee drinks) is recommended.

      “When you have a large amount of sugar like that, especially as a liquid, it gets into your bloodstream very quickly,” adds Cree. “And so you then release a ton of insulin that goes to the ovary, and you make a bunch of testosterone.” 


      More exercise is also recommended for both weight loss and weight maintenance, Cree says: “Food changes and better activity work directly to lower insulin, to lower testosterone.”


    • Metformin: Even though it’s a medication for type 2 diabetes, it’s used in patients with PCOS because it can reduce insulin levels, and as a result, lower testosterone levels. 

    What should I keep in mind if I have (or think I may have) PCOS?

    If your periods are irregular or you have acne, facial hair, or hair loss, tell your provider—it could be a sign that you have PCOS or another condition. And ask questions.

    “I call periods a vital sign for women, if you’re not taking hormones,” Cree says. “Our bodies are really smart: Periods are to get pregnant, and if our body senses that we’re not healthy enough to get pregnant, then we don’t have periods. That means we’ve got to figure out why.” 

    Once you’re diagnosed, Ottey recommends that you “don’t go through extremes, yo-yo dieting, or trying to achieve massive weight loss—it only rebounds.” 

    She adds that “when you get this diagnosis, [there’s] a lot that might feel like it’s being taken away from you: ‘Don’t do this. Don’t eat this. Don’t do that.’ But what I want everyone to think of is what brings you joy, and do more of that and incorporate a lot of healthy activities into your life.”

  • Too Much Or Too Little Testosterone?
  • Widen the Window – by Dr. Elizabeth Stanley

    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.

    Firstly, about the title… That “window” that the author bids us “widen” is not a flowery metaphor, but rather, is referring to the window of exhibited resilience to stress/trauma; the “window” in question looks like an “inverted U” bell-curve on the graph.

    In other words: Dr. Stanley’s main premise here is that we respond best to moderate stress (i.e: in that window, the area under the curve!), but if there is too little or too much, we don’t do so well. The key, she argues, is widening that middle part (expanding the area under the curve) in which we perform optimally. That way, we can still function in a motivated fashion without extrinsic threats, and we also don’t collapse under the weight of overwhelm, either.

    The main strength of this book, however, lies in its practical exercises to accomplish that—and more.

    “And more”, because the subtitle also promised recovery from trauma, and the author delivers in that regard too. In this case, it’s about widening that same window, but this time to allow one’s parasympathetic nervous system to recognize that the traumatic event is behind us, and no longer a threat; we are safe now.

    Bottom line: if you would like to respond better to stress, and/or recover from trauma, this book is a very good tool.

  • How much weight do you actually need to lose? It might be a lot less than you think

    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.

    If you’re one of the one in three Australians whose New Year’s resolution involved losing weight, it’s likely you’re now contemplating what weight-loss goal you should actually be working towards.

    But type “setting a weight loss goal” into any online search engine and you’ll likely be left with more questions than answers.

    Sure, the many weight-loss apps and calculators available will make setting this goal seem easy. They’ll typically use a body mass index (BMI) calculator to confirm a “healthy” weight and provide a goal weight based on this range.

    Your screen will fill with trim-looking influencers touting diets that will help you drop ten kilos in a month, or ads for diets, pills and exercise regimens promising to help you effortlessly and rapidly lose weight.

    Most sales pitches will suggest you need to lose substantial amounts of weight to be healthy – making weight loss seem an impossible task. But the research shows you don’t need to lose a lot of weight to achieve health benefits.

    Using BMI to define our target weight is flawed

    We’re a society fixated on numbers. So it’s no surprise we use measurements and equations to score our weight. The most popular is BMI, a measure of our body weight-to-height ratio.

    BMI classifies bodies as underweight, normal (healthy) weight, overweight or obese and can be a useful tool for weight and health screening.

    But it shouldn’t be used as the single measure of what it means to be a healthy weight when we set our weight-loss goals. This is because it:

    • fails to consider two critical factors related to body weight and health – body fat percentage and distribution
    • does not account for significant differences in body composition based on gender, ethnicity and age.

    How does losing weight benefit our health?

    Losing just 5–10% of our body weight – between 6 and 12kg for someone weighing 120kg – can significantly improve our health in four key ways.

    1. Reducing cholesterol

    Obesity increases the chances of having too much low-density lipoprotein (LDL) cholesterol – also known as bad cholesterol – because carrying excess weight changes how our bodies produce and manage lipoproteins and triglycerides, another fat molecule we use for energy.

    Having too much bad cholesterol and high triglyceride levels is not good, narrowing our arteries and limiting blood flow, which increases the risk of heart disease, heart attack and stroke.

    But research shows improvements in total cholesterol, LDL cholesterol and triglyceride levels are evident with just 5% weight loss.

    2. Lowering blood pressure

    Our blood pressure is considered high if it reads more than 140/90 on at least two occasions.

    Excess weight is linked to high blood pressure in several ways, including changing how our sympathetic nervous system, blood vessels and hormones regulate our blood pressure.

    Essentially, high blood pressure makes our heart and blood vessels work harder and less efficiently, damaging our arteries over time and increasing our risk of heart disease, heart attack and stroke.

    Like the improvements in cholesterol, a 5% weight loss improves both systolic blood pressure (the first number in the reading) and diastolic blood pressure (the second number).

    A meta-analysis of 25 trials on the influence of weight reduction on blood pressure also found every kilo of weight loss improved blood pressure by one point.

    3. Reducing risk for type 2 diabetes

    Excess body weight is the primary manageable risk factor for type 2 diabetes, particularly for people carrying a lot of visceral fat around the abdomen (belly fat).

    Carrying this excess weight can cause fat cells to release pro-inflammatory chemicals that disrupt how our bodies regulate and use the insulin produced by our pancreas, leading to high blood sugar levels.

    Type 2 diabetes can lead to serious medical conditions if it’s not carefully managed, including damaging our heart, blood vessels, major organs, eyes and nervous system.

    Research shows just 7% weight loss reduces risk of developing type 2 diabetes by 58%.

    4. Reducing joint pain and the risk of osteoarthritis

    Carrying excess weight can cause our joints to become inflamed and damaged, making us more prone to osteoarthritis.

    Observational studies show being overweight doubles a person’s risk of developing osteoarthritis, while obesity increases the risk fourfold.

    Small amounts of weight loss alleviate this stress on our joints. In one study each kilogram of weight loss resulted in a fourfold decrease in the load exerted on the knee in each step taken during daily activities.

    Focus on long-term habits

    If you’ve ever tried to lose weight but found the kilos return almost as quickly as they left, you’re not alone.

    An analysis of 29 long-term weight-loss studies found participants regained more than half of the weight lost within two years. Within five years, they regained more than 80%.

    When we lose weight, we take our body out of its comfort zone and trigger its survival response. It then counteracts weight loss, triggering several physiological responses to defend our body weight and “survive” starvation.

    Just as the problem is evolutionary, the solution is evolutionary too. Successfully losing weight long-term comes down to:

    • losing weight in small manageable chunks you can sustain, specifically periods of weight loss, followed by periods of weight maintenance, and so on, until you achieve your goal weight

    • making gradual changes to your lifestyle to ensure you form habits that last a lifetime.

    Setting a goal to reach a healthy weight can feel daunting. But it doesn’t have to be a pre-defined weight according to a “healthy” BMI range. Losing 5–10% of our body weight will result in immediate health benefits.

    Sleep: 6 Dimensions And 24 Hours!

    A woman with dark hair, planning ahead for better sleep, against a white background.

    This is Dr. Lisa Matricciani, a sleep specialist from the University of South Australia, where she teaches in the School of Health Sciences.

    What does she want us to know?

    Healthy sleep begins before breakfast

    The perfect bedtime routine is all well and good, but we need to begin much earlier in the day, Dr. Matricciani advises.

    Specifically, moderate to vigorous activity early in the day plays a big part.

    Before breakfast is best, but even midday/afternoon exercise is associated with better sleep at night.

    Read more: Daytime Physical Activity is Key to Unlocking Better Sleep

    Plan your time well to sleep—but watch out!

    Dr. Matricciani’s research has also found that while it’s important to plan around getting a good night’s sleep (including planning when this will happen), allocating too much time for sleep results in more restless sleep:

    ❝Allocating more time to sleep was associated with earlier sleep onsets, later sleep offsets, less efficient and more consistent sleep patterns for both children and adults.❞

    It is not! Although that’s one part of it. You may remember our previous main feature:

    The 6 Dimensions Of Sleep (And Why They Matter)

    Dr. Matricciani agrees:
