Dr. Greger’s 21 Tweaks… We say 20, though!

We’ve talked before about Dr. Greger’s Daily Dozen (12 things he advises that we make sure to eat each day, to enjoy healthy longevity), but much less-talked-about are his “21 Tweaks”…

They are, in short, a collection of little adjustments one can make for better health. Some of them are also nutritional, but many are more like lifestyle tweaks. Let’s do a rundown:

At each meal:

  • Preload with water
  • Preload with “negative calorie” foods (especially: greens)
  • Incorporate vinegar (1-2 tbsp in a glass of water will slow your blood sugar increase)
  • Enjoy undistracted meals
  • Follow the 20-minute rule (enjoy your meal over the course of at least 20 minutes)

Get your daily doses:

  • Black cumin ¼ tsp
  • Garlic powder ¼ tsp
  • Ground ginger (1 tsp) or cayenne pepper (½ tsp)
  • Nutritional yeast (2 tsp)
  • Cumin (½ tsp)
  • Green tea (3 cups)

Every day:

  • Stay hydrated
  • Deflour your diet
  • Front-load your calories (this means implementing the “king, prince, pauper” rule—try to make your breakfast the largest meal of your day, followed my a medium lunch, and a small evening meal)
  • Time-restrict your eating (eat your meals within, for example, an 8-hour window, and fast the rest of the time)
  • Optimize exercise timing (before breakfast is best for most people, unless you are diabetic)
  • Weigh yourself twice a day (doing this when you get up and when you go to bed results in much better long-term weight management than weighing only once per day)
  • Complete your implementation intentions (this sounds a little wishy-washy, but it’s about building a set of “if this, then that” principles, and then living by them. An example could be directly physical health-related such as “if there is a choice of stairs or elevator, I will take the stairs”, or could be more about holistic good-living, such as “if someone asks me for help, I will try to oblige them so far as I reasonably can”)

Every night:

  • Fast after 7pm
  • Get sufficient sleep (7–9 hours is best. As we get older, we tend more towards the lower end of that, but try get at least those 7 hours!)
  • Experiment with Mild Trendelenburg (better yet, skip this one)*

*This involves a 6º elevation of the bed, at the foot end. Dr. Greger advises that this should only be undertaken after consulting your doctor, though, as a lot of health conditions can contraindicate it. We at 10almonds couldn’t find any evidence to support this practice, and numerous warnings against it, so we’re going to go ahead and say we think this one’s skippable.

Again, we do try to bring you the best evidence-based stuff here at 10almonds, and we’re not going to recommend something just because of who suggested it

As for the rest, you don’t have to do them all! And you may have noticed there was a little overlap in some of them. But, we consider them a fine menu of healthy life hacks from which to pick and choose!

  • From straight to curly, thick to thin: here’s how hormones and chemotherapy can change your hair

    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.

    Head hair comes in many colours, shapes and sizes, and hairstyles are often an expression of personal style or cultural identity.

    Many different genes determine our hair texture, thickness and colour. But some people’s hair changes around the time of puberty, pregnancy or after chemotherapy.

    So, what can cause hair to become curlier, thicker, thinner or grey?

    Curly or straight? How hair follicle shape plays a role

    Hair is made of keratin, a strong and insoluble protein. Each hair strand grows from its own hair follicle that extends deep into the skin.

    Curly hair forms due to asymmetry of both the hair follicle and the keratin in the hair.

    Follicles that produce curly hair are asymmetrical and curved and lie at an angle to the surface of the skin. This kinks the hair as it first grows.

    The asymmetry of the hair follicle also causes the keratin to bunch up on one side of the hair strand. This pulls parts of the hair strand closer together into a curl, which maintains the curl as the hair continues to grow.

    Follicles that are symmetrical, round and perpendicular to the skin surface produce straight hair.

    A diagram shows the hair follicle shape of straight, curly and coiled hair.

    Life changes, hair changes

    Our hair undergoes repeated cycles throughout life, with different stages of growth and loss.

    Each hair follicle contains stem cells, which multiply and grow into a hair strand.

    Head hairs spend most of their time in the growth phase, which can last for several years. This is why head hair can grow so long.

    Let’s look at the life of a single hair strand. After the growth phase is a transitional phase of about two weeks, where the hair strand stops growing. This is followed by a resting phase where the hair remains in the follicle for a few months before it naturally falls out.

    The hair follicle remains in the skin and the stems cells grow a new hair to repeat the cycle.

    Each hair on the scalp is replaced every three to five years.

    Hormone changes during and after pregnancy alter the usual hair cycle

    Many women notice their hair is thicker during pregnancy.

    During pregnancy, high levels of oestrogen, progesterone and prolactin prolong the resting phase of the hair cycle. This means the hair stays in the hair follicle for longer, with less hair loss.

    A drop in hormones a few months after delivery causes increased hair loss. This is due to all the hairs that remained in the resting phase during pregnancy falling out in a fairly synchronised way.

    Hair can change around puberty, pregnancy or after chemotherapy

    This is related to the genetics of hair shape, which is an example of incomplete dominance.

    Incomplete dominance is when there is a middle version of a trait. For hair, we have curly hair and straight hair genes. But when someone has one curly hair gene and one straight hair gene, they can have wavy hair.

    Hormonal changes that occur around puberty and pregnancy can affect the function of genes. This can cause the curly hair gene of someone with wavy hair to become more active. This can change their hair from wavy to curly.

    Researchers have identified that activating specific genes can change hair in pigs from straight to curly.

    Chemotherapy has very visible effects on hair. Chemotherapy kills rapidly dividing cells, including hair follicles, which causes hair loss. Chemotherapy can also have genetic effects that influence hair follicle shape. This can cause hair to regrow with a different shape for the first few cycles of hair regrowth.

    Hormonal changes as we age also affect our hair

    Throughout life, thyroid hormones are essential for production of keratin. Low levels of thyroid hormones can cause dry and brittle hair.

    Oestrogen and androgens also regulate hair growth and loss, particularly as we age.

    Balding in males is due to higher levels of androgens. In particular, high dihydrotestosterone (sometimes shortened to DHT), which is produced in the body from testosterone, has a role in male pattern baldness.

    Some women experience female pattern hair loss. This is caused by a combination of genetic factors plus lower levels of oestrogen and higher androgens after menopause. The hair follicles become smaller and smaller until they no longer produce hairs.

    Reduced function of the cells that produce melanin (the pigment that gives our hair colour) is what causes greying.The Conversation

  • South Indian-Style Chickpea & Mango Salad

    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 have a double-dose of chickpeas today, but with all the other ingredients, this dish is anything but boring. Fun fact about chickpeas though: they’re rich in sitosterol, a plant sterol that, true to its name, sits on cholesterol absorption sites, reducing the amount of dietary cholesterol absorbed. If you are vegan, this will make no difference to you because your diet does not contain cholesterol, but for everyone else, this is a nice extra bonus!

    You will need

    • 1 can white chickpeas, drained and rinsed
    • 1 can black chickpeas (kala chana), drained and rinsed
    • 9 oz fresh mango, diced (or canned is fine if that’s what’s available)
    • 1½ oz ginger, peeled and grated
    • 2 green chilis, finely chopped (adjust per heat preferences)
    • 2 tbsp desiccated coconut (or 3 oz grated coconut, if you have it fresh)
    • 8 curry leaves (dried is fine if that’s what’s available)
    • 1 tsp mustard seeds
    • 1 tsp cumin seeds
    • 1 tsp black pepper, coarse ground
    • ½ tsp MSG or 1 tsp low-sodium salt
    • Juice of 1 lime
    • Extra virgin olive oil

    Method

    (we suggest you read everything at least once before doing anything)

    1) Heat some oil in a skillet over a medium heat. When it’s hot but not smoking, add the ginger, chilis, curry leaves, mustard seeds, and cumin seeds, stirring well to combine, keep going until the mustard seeds start popping.

    2) Add the chickpeas (both kinds), as well as the black pepper and the MSG/salt. Once they’re warm through, take it off the heat.

    3) Add the mango, coconut, and lime juice, mixing thoroughly.

    4) Serve warm, at room temperature, or cold:

    Enjoy!

  • What Grief Does To Your Body (And How To Manage It)

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    What Grief Does To The Body (And How To Manage It)

    In life, we will almost all lose loved ones and suffer bereavement. For most people, this starts with grandparents, eventually moves to parents, and then people our own generation; partners, siblings, close friends. And of course, sometimes and perhaps most devastatingly, we can lose people younger than ourselves.

    For something that almost everyone suffers, there is often very little in the way of preparation given beforehand, and afterwards, a condolences card is nice but can’t do a lot for our mental health.

    And with mental health, our physical health can go too, if we very understandably neglect it at such a time.

    So, how to survive devastating loss, and come out the other side, hopefully thriving? It seems like a tall order indeed.

    First, the foundations:

    You’re probably familiar with the stages of grief. In their most commonly-presented form, they are:

    1. Denial
    2. Anger
    3. Bargaining
    4. Depression
    5. Acceptance

    You’ve probably also heard/read that we won’t always go through them in order, and also that grief is deeply personal and proceeds on its own timescale.

    It is generally considered healthy to go through them.

    What do they look like?

    Naturally this can vary a lot from person to person, but examples in the case of bereavement could be:

    1. Denial: “This surely has not really happened; I’ll carry on as though it hasn’t”
    2. Anger: “Why didn’t I do xyz differently while I had the chance?!”
    3. Bargaining: “I will do such-and-such in their honor, and this will be a way of expressing the love I wish I could give them in a way they could receive”
    4. Depression: “What is the point of me without them? The sooner I join them, the better.”
    5. Acceptance: “I was so lucky that we had the time together that we did, and enriched each other’s lives while we could”

    We can speedrun these or we can get stuck on one for years. We can bounce back and forth. We can think we’re at acceptance, and then a previous stage will hit us like a tonne of bricks.

    What if we don’t?

    Assuming that our lost loved one was indeed a loved one (as opposed to someone we are merely societally expected to mourn), then failing to process that grief will tend to have a big impact on our life—and health. These health problems can include:

    As you can see, three out of five of those can result in death. The other two aren’t great either. So why isn’t this taken more seriously as a matter of health?

    Death is, ironically, considered something we “just have to live with”.

    But how?

    Coping strategies

    You’ll note that most of the stages of grief are not enjoyable per se. For this reason, it’s common to try to avoid them—hence denial usually being first.

    But, that is like not getting a lump checked out because you don’t want a cancer diagnosis. The emotional reasoning is understandable, but it’s ultimately self-destructive.

    First, have a plan. If a death is foreseen, you can even work out this plan together.

    But even if that time has now passed, it’s “better late than never” to make a plan for looking after yourself, e.g:

    • How you will try to get enough sleep (tricky, but sincerely try)
    • How you will remember to eat (and ideally, healthily)
    • How you will still get exercise (a walk in the park is fine; see some greenery and get some sunlight)
    • How you will avoid self-destructive urges (from indirect, e.g. drinking, to direct, e.g. suicidality)
    • How you will keep up with the other things important in your life (work, friends, family)
    • How you will actively work to process your grief (e.g. journaling, or perhaps grief counselling)

    Some previous articles of ours that may help:

    If it works, it works

    If we are all unique, then any relationship between any two people is uniqueness squared. Little wonder, then, that our grief may be unique too. And it can be complicated further:

    • Sometimes we had a complicated relationship with someone
    • Sometimes the circumstances of their death were complicated

    There is, for that matter, such a thing as “complicated grief”:

    Read more: Complicated grief and prolonged grief disorder (Medical News Today)

    We also previously reviewed a book on “ambiguous loss”, exploring grieving when we cannot grieve in the normal way because someone is gone and/but/maybe not gone.

    For example, if someone is in a long-term coma from which they may never recover, or if they are missing-presumed-dead. Those kinds of situations are complicated too.

    Unusual circumstances may call for unusual coping strategies, so how can we discern what is healthy and what isn’t?

    The litmus test is: is it enabling you to continue going about your life in a way that allows you to fulfil your internal personal aspirations and external social responsibilities? If so, it’s probably healthy.

    Look after yourself. And if you can, tell your loved ones you love them today.

  • Cashew & Chickpea Balti

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    When it comes to curries, the humble balti is perhaps the best when you don’t have all day to let something simmer. Filled with healthful spices, this one also comes complete with lots of fiber as well as healthy proteins and fats, with most of its calories coming from the nuts themselves, and the haricot paste base makes for a deliciously creamy curry without having to add anything unhealthy.

    You will need

    • 1 cup cashews, soaked in warm water for at least 5 minutes, and drained (if allergic, omit)
    • 1 can chickpeas (keep the water)
    • 1 can haricot beans (keep the water)
    • 1 can crushed tomatoes
    • 2 medium (or 3 small) red onions, sliced
    • red or green chilis, quantity per your preference re heat, chopped
    • ½ bulb garlic, crushed
    • ½ oz fresh ginger, peeled and finely chopped
    • 1 tbsp tomato paste
    • 1 tbsp garam masala
    • 1 tbsp ground coriander
    • 1 tbsp black pepper, coarse ground
    • 2 tsp turmeric
    • 1 tsp mustard seeds (if allergic, omit)
    • 1 tsp sweet cinnamon
    • 1 tsp coriander seeds
    • ½ tsp MSG or 1 tsp low-sodium salt
    • Avocado oil, for frying (extra virgin olive-oil, or cold-pressed coconut oil, are fine alternatives)
    • Garnish: handful fresh cilantro, chopped (or parsley, if you have the “cilantro tastes like soap” gene)

    Method

    (we suggest you read everything at least once before doing anything)

    1) Heat a little oil in a large sauté pan (we’re going to need space to work; a large wok is traditional but a sauté pan is convenient), and add the garlic, ginger, mustard seeds, and coriander seeds, stirring for about 2 minutes, then add the onions and chilis, stirring for another 3 minutes. The onions and chilis won’t be fully cooked yet, but that’s fine, we just needed to get them started.

    2) Add the crushed tomatoes, stirring them in, and when they get to temperature, turn the heat down to a simmer.

    3) Add the chickpeas to the pan, but separately put the chickpea water into a high-speed blender.

    4) Add the haricot beans, including the water they came in, to the high-speed blender, as well as the tomato paste and the remaining spices (including the MSG or salt), and blend on high until smooth. Add the curry paste (that’s what you’ve just made in the blender) to the pan, and stir in well.

    5) Add the cashews, stirring in well. Taste, and adjust any spices if necessary for your liking. If the onions still aren’t fully cooked, let them simmer until they are, but it shouldn’t take long.

    10almonds tip: if perchance you made it too spicy, you can add a little lime juice and the acidity will counteract the heat. Adding lemon juice, lime juice, or some kind of vinegar (depending on what works with the flavor profile of your recipe) is a good last resort to have up your sleeve for fixing a dish that got too spicy.

    6) Add the garnish, and serve—we recommend serving it with our Tasty Versatile Rice, but any carb is fine.

    Enjoy!

  • Kate Middleton is having ‘preventive chemotherapy’ for cancer. What does this mean?

    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.

    Catherine, Princess of Wales, is undergoing treatment for cancer. In a video thanking followers for their messages of support after her major abdominal surgery, the Princess of Wales explained, “tests after the operation found cancer had been present.”

    “My medical team therefore advised that I should undergo a course of preventative chemotherapy and I am now in the early stages of that treatment,” she said in the two-minute video.

    No further details have been released about the Princess of Wales’ treatment.

    But many have been asking what preventive chemotherapy is and how effective it can be. Here’s what we know about this type of treatment.

    It’s not the same as preventing cancer

    To prevent cancer developing, lifestyle changes such as diet, exercise and sun protection are recommended.

    Tamoxifen, a hormone therapy drug can be used to reduce the risk of cancer for some patients at high risk of breast cancer.

    Aspirin can also be used for those at high risk of bowel and other cancers.

    How can chemotherapy be used as preventive therapy?

    In terms of treating cancer, prevention refers to giving chemotherapy after the cancer has been removed, to prevent the cancer from returning.

    If a cancer is localised (limited to a certain part of the body) with no evidence on scans of it spreading to distant sites, local treatments such as surgery or radiotherapy can remove all of the cancer.

    If, however, cancer is first detected after it has spread to distant parts of the body at diagnosis, clinicians use treatments such as chemotherapy (anti-cancer drugs), hormones or immunotherapy, which circulate around the body .

    The other use for chemotherapy is to add it before or after surgery or radiotherapy, to prevent the primary cancer coming back. The surgery may have cured the cancer. However, in some cases, undetectable microscopic cells may have spread into the bloodstream to distant sites. This will result in the cancer returning, months or years later.

    With some cancers, treatment with chemotherapy, given before or after the local surgery or radiotherapy, can kill those cells and prevent the cancer coming back.

    If we can’t see these cells, how do we know that giving additional chemotherapy to prevent recurrence is effective? We’ve learnt this from clinical trials. Researchers have compared patients who had surgery only with those whose surgery was followed by additional (or often called adjuvant) chemotherapy. The additional therapy resulted in patients not relapsing and surviving longer.

    How effective is preventive therapy?

    The effectiveness of preventive therapy depends on the type of cancer and the type of chemotherapy.

    Let’s consider the common example of bowel cancer, which is at high risk of returning after surgery because of its size or spread to local lymph glands. The first chemotherapy tested improved survival by 15%. With more intense chemotherapy, the chance of surviving six years is approaching 80%.

    Preventive chemotherapy is usually given for three to six months.

    How does chemotherapy work?

    Many of the chemotherapy drugs stop cancer cells dividing by disrupting the DNA (genetic material) in the centre of the cells. To improve efficacy, drugs which work at different sites in the cell are given in combinations.

    Chemotherapy is not selective for cancer cells. It kills any dividing cells.

    But cancers consist of a higher proportion of dividing cells than the normal body cells. A greater proportion of the cancer is killed with each course of chemotherapy.

    Normal cells can recover between courses, which are usually given three to four weeks apart.

    What are the side effects?

    The side effects of chemotherapy are usually reversible and are seen in parts of the body where there is normally a high turnover of cells.

    The production of blood cells, for example, is temporarily disrupted. When your white blood cell count is low, there is an increased risk of infection.

    Cell death in the lining of the gut leads to mouth ulcers, nausea and vomiting and bowel disturbance.

    Certain drugs sometimes given during chemotherapy can attack other organs, such as causing numbness in the hands and feet.

    There are also generalised symptoms such as fatigue.

    Given that preventive chemotherapy given after surgery starts when there is no evidence of any cancer remaining after local surgery, patients can usually resume normal activities within weeks of completing the courses of chemotherapy.The Conversation

  • The Reason You’re 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.

    If you are feeling lonely, then there are likely reasons why, as Kurtzgesagt explains:

    Why it happens and how to fix it

    Many people feel lonely and disconnected, often not knowing how to make new friends. And yet, social connection strongly predicts happiness, while lack of it is linked to diseases and a shorter life.

    One mistake that people make is thinking it has to be about shared interests; that can help, but proximity and shared time are much more important.

    Another stumbling block for many is that adult responsibilities and distractions (work, kids, technology) often take priority over friendships—but loneliness is surprisingly highest among young people, worsened by the pandemic’s impact on social interactions.

    And even when friendships are made, they fade without attention, often accidentally, impacting both people involved. Other friendships can be lost following big life changes such as moving house or the end of a relationship. And for people above a certain advanced age, friendship groups can shrink due to death, if one’s friends are all in the same age group.

    But, all is not lost. We can make friends with people of any age, and old friendships can be revived by a simple invitation. We can also take a “build it and they will come” approach, by organizing events and being the one who invites others.

    It’s easy to fear rejection—most people do—but it’s worth overcoming for the potential rewards. That said, building friendships requires time, patience, caring about others, and being open about yourself, which can involve a degree of vulnerability too.

    In short: be laid-back while still prioritizing friendships, show genuine interest, and stay open to social opportunities.
