Our Verdict

When comparing black tea to green tea, we picked the black tea.

Why?

It was close! Ultimately we picked the black tea as the “best all-rounder”.

Both teas are great for the health, insofar as tea in general is a) a very good way to hydrate (better absorption than plain water) and b) an excellent source of beneficial phytochemicals—mostly antioxidants of various kinds, but there’s a lot in there.

We did a run-down previously of the relative benefits of each of four kinds of tea (black, white, green, red):

Which Tea Is Best, By Science?

Which concluded in its final summary:

Black, white, green, and red teas all have their benefits, and ultimately the best one for you will probably be the one you enjoy drinking, and thus drink more of.

If trying to choose though, we offer the following summary:

  • Black tea: best for total beneficial phytochemicals
  • White tea:best for your oral health
  • Green tea: best for your brain
  • ❤️ Red tea: best if you want naturally caffeine-free

Enjoy!

  • When Carbs, Proteins, & Fats Switch Metabolic Roles

    Strange Things Happening In The Islets Of Langerhans

    It is generally known and widely accepted that carbs have the biggest effect on blood sugar levels (and thus insulin response), fats less so, and protein least of all.

    And yet, there was a groundbreaking study published yesterday which found:

    Glucose is the well-known driver of insulin, but we were surprised to see such high variability, with some individuals showing a strong response to proteins, and others to fats, which had never been characterized before.

    Insulin plays a major role in human health, in everything from diabetes, where it is too low*, to obesity, weight gain and even some forms of cancer, where it is too high.

    These findings lay the groundwork for personalized nutrition that could transform how we treat and manage a range of conditions.❞

    ~ Dr. James Johnson

    *saying ”too low” here is potentially misleading without clarification; yes, Type 1 Diabetics will have too little [endogenous] insulin (because the pancreas is at war with itself and thus isn’t producing useful quantities of insulin, if any). Type 2, however, is more a case of acquired insulin insensitivity, because of having too much at once too often, thus the body stops listening to it, “boy who cried wolf”-style, and the pancreas also starts to get fatigued from producing so much insulin that’s often getting ignored, and does eventually produce less and less while needing more and more insulin to get the same response, so it can be legitimately said “there’s not enough”, but that’s more of a subjective outcome than an objective cause.

    Back to the study itself, though…

    What they found, and how they found it

    Researchers took pancreatic islets from 140 heterogenous donors (varied in age and sex; ostensibly mostly non-diabetic donors, but they acknowledge type 2 diabetes could potentially have gone undiagnosed in some donors*) and tested cell cultures from each with various carbs, proteins, and fats.

    They found the expected results in most of the cases, but around 9% responded more strongly to the fats than the carbs (even more strongly than to glucose specifically), and even more surprisingly 8% responded more strongly to the proteins.

    *there were also some known type 2 diabetics amongst the donors; as expected, those had a poor insulin response to glucose, but their insulin response to proteins and fats were largely unaffected.

    What this means

    While this is, in essence, a pilot study (the researchers called for larger and more varied studies, as well as in vivo human studies), the implications so far are important:

    It appears that, for a minority of people, a lot of (generally considered very good) antidiabetic advice may not be working in the way previously understood. They’re going to (for example) put fat on their carbs to reduce the blood sugar spike, which will technically still work, but the insulin response is going to be briefly spiked anyway, because of the fats, which very insulin response is what will lower the blood sugars.

    In practical terms, there’s not a lot we can do about this at home just yet—even continuous glucose monitors won’t tell us precisely, because they’re monitoring glucose, not the insulin response. We could probably measure everything and do some math and work out what our insulin response has been like based on the pace of change in blood sugar levels (which won’t decrease without insulin to allow such), but even that is at best grounds for a hypothesis for now.

    Hopefully, more publicly-available tests will be developed soon, enabling us all to know our “insulin response type” per the proteome predictors discovered in this study, rather than having to just blindly bet on it being “normal”.

    Ironically, this very response may have hidden itself for a while—if taking fats raised insulin response without raising blood sugar levels, then if blood sugar levels are the only thing being measured, all we’ll see is “took fats at dinner; blood sugars returned to normal more quickly than when taking carbs without fats”.

  • Easily Digestible Vegetarian Protein Sources

    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

    ❝What could be easily digestible plant sources of protein for a vegetarian. My son is a gym holic and always looking for ways to get his protein from lentils other than eggs. He says to reach his protein requirement for the day, the amount of lentils he has to eat is sometimes heavy on the gut. Would really appreciate if you throw some light on this ❞

    Unless one has IBS or similar (or is otherwise unaccustomed to consuming healthy amounts of fiber), lentils shouldn’t be at all problematic for the digestion.

    However, the digestive process can still be eased by (speaking specifically for lentils here) blending them (in the water they were cooked in). This thick tasty liquid can then be used as the base of a soup, for example.

    Soy is an excellent source of complete protein too. Your son probably knows this because it’s in a lot of body-building supplements as soy protein isolate, but can also be enjoyed as textured soy protein (as in many plant-based meats), or even just soy beans (edamame). Tofu (also made from soy) is very versatile, and again can be blended to form the basis of a creamy sauce.

    Mycoproteins (as found in “Quorn” brand products and other meat substitutes) also perform comparably to meat from animals:

  • Pumpkin Seeds vs Watermelon Seeds – 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 pumpkin seeds to watermelon seeds, we picked the watermelon.

    Why?

    Starting with the macros: pumpkin seeds have a lot more carbs, while watermelon seeds have a lot more protein, despite pumpkin seeds being famous for such. They’re about equal on fiber. In terms of fats, watermelon seeds are higher in fats, and yes, these are healthy fats, mostly polyunsaturated.

    When it comes to vitamins, pumpkin seeds are marginally higher in vitamins A and C, while watermelon seeds are a lot higher in vitamins B1, B2, B3, B5, B6, and B9. An easy win for watermelon seeds here.

    In the category of minerals, despite being famous for zinc, pumpkin seeds are higher only in potassium, while watermelon seeds are higher in iron, magnesium, manganese, and phosphorus; the two seeds are equal on calcium, copper, and zinc. Another win for watermelon seeds.

    In short, enjoy both, but watermelon has more to offer. Of course, if buying just the seeds and not the whole fruit, it’s generally easier to find pumpkin seeds than watermelon seeds, so do bear in mind that pumpkin seeds’ second place isn’t that bad here—it’s just a case of a very nutritious food looking bad by standing next to an even better one.

    A fiber-rich, heart-healthy take on a classic:

    You will need

    • 1 can chickpeas, drained
    • ¾ cup vegetable stock; ideally you made this yourself from vegetable cuttings that you kept in the freezer for this purpose, but failing that, you should be able to get low-sodium stock cubes at your local supermarket.
    • ¼ cup arrowroot starch (cornstarch will do at a pinch, but arrowroot is better and has no flavor of its own)
    • 3 tbsp coconut oil
    • 2 tbsp grated fresh ginger
    • ¼ bulb garlic, minced
    • 2 tbsp honey (or maple syrup if you prefer, and if you don’t like sweetness, reduce this to 1 tbsp or even omit entirely, though it won’t be quite so “General Tso” if you do, but it’s your meal!)
    • 2 tbsp tomato paste
    • 2 tsp hot sauce
    • 1 tsp black pepper, coarse ground
    • 3 green onions, sliced

    Method

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

    1) Coat the chickpeas in the arrowroot starch by tossing them together in a bowl

    2) Heat the coconut oil in a skillet on a medium-high heat, and when hot, add the chickpeas, stirring for 3 minutes

    3) Add the remaining ingredients in the order we gave (except the vegetable stock, which goes in last), stirring for 5 more minutes, or until the sauce thickens

    4) Serve with the carb of your choice; we recommend our Tasty Versatile Rice Recipe

    Enjoy!

    It’s time to party with these delicious snacks, which are great as an hors d’œuvre, amuse-bouche, or part of a buffet. And like all our offerings, they’re very healthy too—in this case, especially for the gut and heart!

    You will need

    • 1 cucumber, sliced
    • 1 cup pitted Kalamata olives (or other black olives)
    • 1 cup sun-dried tomatoes
    • 2 oz feta cheese (or vegan equivalent, or pine nuts)
    • 2 tbsp extra virgin olive oil
    • 1 tbsp fresh basil, chopped
    • 2 tsp black pepper, coarse ground

    Method

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

    1) Make the first topping by combining the olives, half the olive oil, and half the black pepper, into a food processor and blending until it is a coarse pâté.

    2) Make the second topping by doing the same with the tomatoes, basil, feta cheese (or substitution), and the other half of the olive oil and black pepper, again until it is a coarse pâté.

    3) Assemble the canapés-crudités by topping the cucumber slices alternately with the two toppings, and serve:

  • Treat Your Own Knee – by Robin McKenzie

    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.

    First, a note about the author: he’s a physiotherapist and not a doctor, but with 40 years of practice to his name and 33 letters after his name (CNZM OBE FCSP (Hon) FNZSP (Hon) Dip MDT Dip MT), he seems to know his stuff.

    The book covers recognizing the difference between arthritis, degeneration, or normal wear and tear, before narrowing down what your actual problem is and what can be done about it.

    While there are many possible causes of knee pain (and by causes, we mean the first-level cause, such as “bad posture” or “old sports injury” or “inflammatory diet” or “repetitive strain” etc, not second-level causes that are also symptoms, like inflammation), McKenzie’s approach involves customizing his system to your body’s specific problems and needs. That’s what most of the book is about.

    The style is direct and to-the-point; there’s no sensationalization here nor a feel of being sold anything. There’s lots of science scattered throughout, but all with the intent of enabling the reader to understand what’s going on with the problems, processes, and solutions, and why/how the things that work, work. Where there are exercises offered they are clearly-described and well-illustrated.

    Bottom line: this is not a fancy book but it is an effective one. If you have knee pain, this is a very worthwhile one to read.
