Vit D + Calcium: Too Much Of A Good Thing?
- Myth: you can’t get too much calcium!
- Myth: you must get as much vitamin D as possible!
Let’s tackle calcium first:
❝Calcium is good for you! You need more calcium for your bones! Be careful you don’t get calcium-deficient!❞
Contingently, those comments seem reasonable. Contingently on you not already having the right amount of calcium. Most people know what happens in the case of too little calcium: brittle bones, osteoporosis, and so forth.
But what about too much?
Hypercalcemia
Having too much calcium—or “hypercalcemia”— can lead to problems with…
- Groans: gastrointestinal pain, nausea, and vomiting. Peptic ulcer disease and pancreatitis.
- Bones: bone-related pains. Osteoporosis, osteomalacia, arthritis and pathological fractures.
- Stones: kidney stones causing pain.
- Moans: refers to fatigue and malaise.
- Thrones: polyuria, polydipsia, and constipation
- Psychic overtones: lethargy, confusion, depression, and memory loss.
(mnemonic courtesy of Sadiq et al, 2022)
What causes this, and how do we avoid it? Is it just dietary?
It’s mostly not dietary!
Overconsumption of calcium is certainly possible, but not common unless one has an extreme diet and/or over-supplementation. However…
Too much vitamin D
Again with “too much of a good thing”! While keeping good levels of vitamin D is, obviously, good, overdoing it (including commonly prescribed super-therapeutic doses of vitamin D) can lead to hypercalcemia.
This happens because vitamin D triggers calcium absorption into the gut, and acts as gatekeeper to the bloodstream.
Normally, the body only absorbs 10–20% of the calcium we consume, and that’s all well and good. But with overly high vitamin D levels, the other 80–90% can be waved on through, and that is very much Not Good™.

- Hypercalcemia of Malignancy: An Update on Pathogenesis and Management
- Vitamin D-Mediated Hypercalcemia: Mechanisms, Diagnosis, and Treatment
How much is too much?
The United States’ Office of Dietary Supplements defines 4000 IU (100μg) as a high daily dose of vitamin D, and recommends 600 IU (15μg) as a daily dose, or 800 IU (20μg) if aged over 70.

Body Sculpting with Kettlebells for Women – by Lorna Kleidman
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 those of us who are more often lifting groceries or pots and pans than bodybuilding trophies, kettlebells provide a way of training functional strength. This book does (as per the title) offer both sides of things—the body sculpting, and thebody maintenance free from pain and injury.
Kleidman first explains the basics of kettlebell training, and how to get the most from one’s workouts, before discussing what kinds of exercises are best for which benefits, and finally moving on to provide full exercise programs.
The exercise programs themselves are fairly comprehensive without being unduly detailed, and give a week-by-week plan for getting your body to where you want it to be.
The style is fairly personal and relaxed, while keeping things quite clear—the photographs are also clear, though if there’s a weakness here, it’s that we don’t get to see which muscles are being worked in the same as we do when there’s an illustration with a different-colored part to show that.
Bottom line: if you’re looking for an introductory course for kettlebell training that’ll take you from beginner through to the “I now know what I’m doing and can take it from here, thanks” stage.

Fast Diet, Fast Exercise, Fast Improvements

Diet & Exercise, Optimized
This is Dr. Michael Mosley. He originally trained in medicine with the intention of becoming a psychiatrist, but he grew disillusioned with psychiatry as it was practised, and ended up pivoting completely into being a health educator, in which field he won the British Medical Association’s Medical Journalist of the Year Award.
He also died under tragic circumstances very recently (he and his wife were vacationing in Greece, he went missing while out for a short walk on the 5th of June, appears to have got lost, and his body was found 100 yards from a restaurant on the 9th). All strength and comfort to his family; we offer our small tribute here today in his honor.
The “weekend warrior” of fasting
Dr. Mosley was an enjoyer (and proponent) of intermittent fasting, which we’ve written about before:
Fasting Without Crashing? We Sort The Science From The Hype
However, while most attention is generally given to the 16:8 method of intermittent fasting (fast for 16 hours, eat during an 8 hour window, repeat), Dr. Mosley preferred the 5:2 method (which generally means: eat at will for 5 days, then eat a reduced calorie diet for the other 2 days).
Specifically, he advocated putting that cap at 800 kcal for each of the weekend days (doesn’t have to be specifically the weekend).
He also tweaked the “eat at will for 5 days” part, to “eat as much as you like of a low-carb Mediterranean diet for 5 days”:
❝The “New 5:2” approach involves restricting calories to 800 on fasting days, then eating a healthy lower carb, Mediterranean-style diet for the rest of the week.
The beauty of intermittent fasting means that as your insulin sensitivity returns, you will feel fuller for longer on smaller portions. This is why, on non-fasting days, you do not have to count calories, just eat sensible portions. By maintaining a Mediterranean-style diet, you will consume all of the healthy fats, protein, fibre and fresh plant-based food that your body needs.❞

Knowledge is power
Dr. Mosley encouraged the use of genotyping tests for personal health, not just to know about risk factors, but also to know about things such as, for example, whether you have the gene that makes you unable to gain significant improvements in aerobic fitness by following endurance training programs:
The Real Benefit Of Genetic Testing
On which note, he himself was not a fan of exercise, but recognised its importance, and instead sought to minimize the amount of exercise he needed to do, by practising High Intensity Interval Training. We reviewed a book of his (teamed up with a sports scientist) not long back; here it is:
Fast Exercise: The Simple Secret of High Intensity Training – by Dr. Michael Mosley & Peta Bee
You can also read our own article on the topic, here:

Just One Thing…
As well as his many educational TV shows, Dr. Mosley was also known for his radio show, “Just One Thing”, and a little while ago we reviewed his book, effectively a compilation of these:

Genius Foods – by Max Lugavere
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 is a lot of seemingly conflicting (or sometimes: actually conflicting!) information out there with regard to nutrition and various aspects of health. Why, for example, are we told:
- Be sure to get plenty of good healthy fats from nuts and seeds, for metabolic health and brain health too!
- But these terrible nut and seed oils lead to heart disease and dementia! Avoid them at all costs!
Max Lugavere demystifies this and more.
His science-led approach is primarily focused on avoiding dementia, and/but is at least not bad when it comes to other areas of health too.
He takes us on a tour of different parts of our nutrition, including:
- Perhaps the clearest explanation of “healthy” vs “unhealthy” fats this reviewer has read
- Managing carbs (simple and complex) for healthy glucose management—essential for good brain health
- What foods to improve or reduce—a lot you might guess, but this is a comprehensive guide to brain health so it’d be remiss to skip it
- The role that intermittent fasting can play as a bonus extra
While the main thrust of the book is about avoiding cognitive impairment in the long-term (including later-life dementia), he makes good, evidence-based arguments for how this same dietary plan improves cognitive function in the short-term, too.
Speaking of that dietary plan: he does give a step-by-step guide in a “make this change first, then this, then this” fashion, and offers some sample recipes too. This is by no means a recipe book though—most of the book is taking us through the science, not the kitchen.
Bottom line: this is the book for getting unconfused with regard to diet and brain health, making a lot of good science easy to understand. Which we love!

Broccoli vs Cauliflower – 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 broccoli to cauliflower, we picked the broccoli.
Why?
This one is quite straightforward. Superficially, they’re very similar:
Both are great cruciferous vegetables with many health benefits to offer. Even for those keen to avoid oxalates, which cruciferous vegetables in general can be high in, these ones are quite low.
However, if you have IBS, you might want to avoid both, for their raffinose content that may cause problems for you.
For pretty much everyone else, unless you have a special reason why it’s not the case for you, both are a good source of abundant vitamins and minerals, and yet…
Anything cauliflower can do, broccoli can do better!
Broccoli contains more of the vitamins they both contain, and more of the minerals they both contain.
Broccoli also beats cauliflower on amino acids (except lysine), and contains a lot more lutein and zeaxanthin, carotenoids important for healthy eyes and brain.
So by all means enjoy both, but if you’re going to pick one, pick broccoli!

Lycopene’s Benefits For The Gut, Heart, Brain, & More
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 Doesn’t Lycopene Do?
Lycopene is an antioxidant carotenoid famously found in tomatoes; it actually appears in even higher levels in watermelon, though. If you are going to get it from tomato, know that cooking improves the lycopene content rather than removing it (watermelon, on the other hand, can be enjoyed as-is and already has the higher lycopene content).
Antioxidant properties
Let’s reiterate the obvious first, for the sake of being methodical and adding a source. Lycopene is a potent antioxidant with multiple health benefits:
Lycopene: A Potent Antioxidant with Multiple Health Benefits
…and as such, it does all the things you might reasonably expect and antioxidant to do. For example…
Anti-inflammatory properties
In particular, it regulates macrophage activity, reducing inflammation while improving immune response:
Lycopene Regulates Macrophage Immune Response through the Autophagy Pathway Mediated by RIPK1
As can be expected of most antioxidants and anti-inflammatory agents, it also has…
Anticancer properties
Scientific papers tend to be “per cancer type”, so we’re just going to give one example, but there’s pretty much evidence for its utility against most if not all types of cancer. We’re picking prostate cancer though, as it’s one that’s been studied the most in the context of lycopene intake—in this study, for example, it was found that men who enjoyed at least two servings of lycopene-rich tomato sauce per week were 30% less likely to develop prostate cancer than those who didn’t:
Dietary lycopene intake and risk of prostate cancer defined by ERG protein expression
If you’d like to see something more general, however, then check out:
Potential Use of Tomato Peel, a Rich Source of Lycopene, for Cancer Treatment
It also fights Candida albicans
Ok, this is not (usually) so life-and-death as cancer, but reducing our C. albicans content (specifically: in our gut) has a lot of knock-on effects for other aspects of our health, so this isn’t one to overlook:
The title does not make this clear, but yes: this does mean it has an antifungal effect. We mention this because often cellular apoptosis is good for an overall organism, but in this case, it simply kills the Candida.
It’s good for the heart
A lot of studies focus just on triglyceride markers (which lycopene improves), but more tellingly, here’s a 10-year observational study in which diets rich in lycopene were associated to a 17–26% lower risk of heart disease:
Relationship of lycopene intake and consumption of tomato products to incident CVD
…and a 39% overall reduced mortality in, well, we’ll let the study title tell it:
…which means also:
It’s good for the brain
As a general rule of thumb, what’s good for the heart is good for the brain (because the brain needs healthy blood flow to stay healthy, and is especially vulnerable when it doesn’t get that), and in this case that rule of thumb is also borne out by the post hoc evidence, specifically yielding a 31% decreased incidence of stroke:
Dietary and circulating lycopene and stroke risk: a meta-analysis of prospective studies
Is it safe?
As a common food product, it is considered very safe.
If you drink nothing but tomato juice all day for a long time, your skin will take on a reddish hue, which will go away if you stop getting all your daily water intake in tomato juice.
In all likelihood, even if you went to extremes, you would get sick from the excess of vitamin A (generally present in the same foods) sooner than you’d get sick from the excess of lycopene.
Want to try some?
We don’t sell it, and also we recommend simply enjoying tomatoes, watermelons, etc, but if you do want a supplement, here’s an example product on Amazon
Enjoy!

Muhammara
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.
This is a Levantine dish, Syrian in origin (although Lebanese cuisine uses it plenty too) and popularly enjoyed all the way up to Turkey, down to Egypt, and across to Armenia. And today, perhaps rather further afield! It’s first and foremost a spicy dip/spread, though it can be lengthened into a sauce, and/or made more substantial by adding an extra protein. We’ll give you the basic recipe though, and let you see where it takes you! Healthwise, it’s very nutritionally dense, mostly thanks to the walnuts and red peppers, though spices and olive oil bring their healthy benefits too.
You will need
- ½ cup chopped walnuts (ideally: toasted)
- 3 red peppers, from a jar (jarred over fresh not only improves the consistency, but also makes it extra gut-healthy due to the fermentation bacteria present; if you must use fresh, roast them first)
- 2 tbsp extra virgin olive oil
- 1 tbsp pomegranate molasses (you can omit if you don’t like sweetness, but this is traditional)
- 1 tbsp tomato purée
- 1 tbsp Aleppo pepper flakes (less, if you don’t like heat) (substitute another hot pepper if necessary)
- ½ bulb garlic, crushed
- 2 tsp ground smoked paprika
- 1 tsp ground cumin
- ½ tsp MSG or 1 tsp low-sodium salt
- Juice of 1 lemon
- Optional: handful of pomegranate seeds
- Optional: herb garnish, e.g. cilantro or parsley
Method
(we suggest you read everything at least once before doing anything)
1) Add everything except the pomegranate seeds and herbs to a blender, and blend to a smooth consistency.
2) Add the pomegranate seeds and herbs, as a garnish.
3) Serve! Can be enjoyed as a dip (perhaps using our Homemade Healthy Flatbreads recipe), or as a spread, or used as a sauce poured over chickpeas or some other bulky protein, to make a more substantial dish.
Enjoy!
