Bell Peppers: A Spectrum Of Specialties
We were going to do this as part of our ongoing “This Or That?” challenge, but as there are four main types all with many different benefits, we thought this bunch of fruits deserved a main feature.
And yes, they’re botanically fruits, even if culinarily used as vegetables—much like tomatoes, famously!
They’re all the same (but also very much not)
A thing to know is that whether bell peppers be green, yellow, orange, or red, they’re all the same plant, Capiscum anuum. All that differs is how early or late they’re harvested.
Notwithstanding the “Capiscum” genus, they don’t contain capsaicin (as is found in hot peppers). Capsaicin’s a wonderful phytochemical:
Capsaicin For Weight Loss And Against Inflammation
…but today we’re all about the bell peppers.
So, let’s see how they stack up!
💚 Green for lutein
Lutein is especially important for the eyes and [the rest of the] brain, to the point that there’s now an Alzheimer’s test that measures lutein concentration in the eye:
Green peppers have most of this important carotenoid, though the others all have some too. See also:
💛 Yellow for vitamin C
Yellow peppers are technically highest in vitamin C, but all of them contain far more than the daily dose per fruit already, so if there’s any color of pepper that’s nutritionally the most expendable, it’s yellow, since any other color pepper can take its place.
Watch out, though! Cooking destroys vitamin C, so if you want to get your Cs in, you’re going to want to do it raw.
🧡 Orange for zeaxanthin and cryptoxanthins
Similar in their benefits to lutein, these antioxidant carotenoids are found most generously in orange peppers (20x as much as in yellow, 10x as much as in red, and slightly more than in green).
❤️ Red for vitamins A & B6
Red peppers are richest by far in vitamin A, with one fruit giving the daily dose already. The others have about 10% of that, give or take.
Red peppers also have the most vitamin B6, though the others also have nearly as much.
❤️ Red for lycopene
We must do a main feature for lycopene sometime, as unlike a lot of antioxidant carotenoids, lycopene is found in comparatively very few foods (most famously it’s present in tomatoes).
Red is the only color of pepper to have lycopene.
10almonds tip: to get the most out of your lycopene, cook these ones!
Lycopene becomes 4x more bioavailable when cooked:
Lycopene in tomatoes: chemical and physical properties affected by food processing ← this paper is about tomatoes but lycopene is lycopene and this applies to the lycopene in red peppers, too
And the overall winner is…
You! Because you get to eat all four of them
Enjoy!

Dr. Greger’s Anti-Aging Eight
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.
Dr. Greger’s Anti-Aging Eight
This is Dr. Michael Greger. We’ve featured him before: Brain Food? The Eyes Have It!
This time, we’re working from his latest book, the excellent “How Not To Age”, which we reviewed all so recently. It is very information-dense, but we’re going to be focussing on one part, his “anti-aging eight”, that is to say, eight interventions he rates the most highly to slow aging in general (other parts of the book pertained to slowing eleven specific pathways of aging, or preserving specific bodily functions against aging, for example).
Without further ado, his “anti-aging eight” are…
- Nuts
- Greens
- Berries
- Xenohormesis & microRNA manipulation
- Prebiotics & postbiotics
- Caloric restriction / IF
- Protein restriction
- NAD+
As you may have noticed, some of these are things might appear already on your grocery shopping list; others don’t seem so “household”. Let’s break them down:
Nuts, greens, berries
These are amongst the most nutrient-dense and phytochemical-useful parts of the diet that Dr. Greger advocates for in his already-famous “Dr. Greger’s Daily Dozen”.
For brevity, we’ll not go into the science of these here, but will advise you: eat a daily portion of nuts, a daily portion of berries, and a couple of daily portions of greens.
Xenohormesis & microRNA manipulation
You might, actually, have these on your grocery shopping list too!
Hormesis, you may recall from previous editions of 10almonds, is about engaging in a small amount of eustress to trigger the body’s self-strengthening response, for example:
Xenohormesis is about getting similar benefits, second-hand.
For example, plants that have been grown to “organic” standards (i.e. without artificial pesticides, herbicides, fertilizers) have had to adapt to their relatively harsher environment by upping their levels of protective polyphenols and other phytochemicals that, as it turns out, are as beneficial to us as they are to the plants:
Hormetic Effects of Phytochemicals on Health and Longevity
Additionally, the flip side of xenohormesis is that some plant compounds can themselves act as a source of hormetic stress that end up bolstering us. For example:
In essence, it’s not just that it has anti-oxidant effect; it also provides a tiny oxidative-stress immunization against serious sources of oxidative stress—and thus, aging.
MicroRNA manipulation is, alas, too complex to truly summarize an entire chapter in a line or two, but it has to do with genetic information from the food that we eat having a beneficial or deleterious effect to our own health:
Diet-derived microRNAs: unicorn or silver bullet?
A couple of quick takeaways (out of very many) from Dr. Greger’s chapter on this is to spring for the better quality olive oil, and skip the cow’s milk:
- Impact of Phenol-Enriched Virgin Olive Oils on the Postprandial Levels of Circulating microRNAs Related to Cardiovascular Disease
- MicroRNA exosomes of pasteurized milk: potential pathogens of Western diseases
Prebiotics & Postbiotics
We’re short on space, so we’ll link you to a previous article, and tell you that it’s important against aging too:
Making Friends With Your Gut (You Can Thank Us Later)
An example of how one of Dr. Greger’s most-recommended postbiotics helps against aging, by the way:
- The mitophagy activator urolithin A is safe and induces a molecular signature of improved mitochondrial and cellular health in humans
- Urolithin A improves muscle strength, exercise performance, and biomarkers of mitochondrial health in a randomized trial in middle-aged adults
(Urolithin can be found in many plants, and especially those containing tannins)
See also: How to Make Urolithin Postbiotics from Tannins
Caloric restriction / Intermittent fasting
This is about lowering metabolic load and promoting cellular apoptosis (programmed cell death; sounds bad; is good) and autophagy (self-consumption; again, sounds bad; is good).
For example, he cites the intermittent fasters’ 46% lower risk of dying in the subsequent years of follow-up in this longitudinal study:
For brevity we’ll link to our previous IF article, but we’ll revisit caloric restriction in a main feature on of these days:
Fasting Without Crashing? We sort the science from the hype!
Dr. Greger favours caloric restriction over intermittent fasting, arguing that it is easier to adhere to and harder to get wrong if one has some confounding factor (e.g. diabetes, or a medication that requires food at certain times, etc). If adhered to healthily, the benefits appear to be comparable for each, though.
Protein restriction
In contrast to our recent main feature Protein vs Sarcopenia, in which that week’s featured expert argued for high protein consumption levels, protein restriction can, on the other hand, have anti-aging effects. A reminder that our body is a complex organism, and sometimes what’s good for one thing is bad for another!
Dr. Greger offers protein restriction as a way to get many of the benefits of caloric restriction, without caloric restriction. He further notes that caloric restriction without protein restriction doesn’t decrease IGF-1 levels (a marker of aging).
However, for FGF21 levels (these are good and we want them higher to stay younger), what matters more than lowering proteins in general is lowering levels of the amino acid methionine—found mostly in animal products, not plants—so the source of the protein matters:
For example, legumes deliver only 5–10% of the methionine that meat does, for the same amount of protein, so that’s a factor to bear in mind.
NAD+
This is about nicotinamide adenine dinucleotide, or NAD+ to its friends.
NAD+ levels decline with age, and that decline is a causal factor in aging, and boosting the levels can slow aging:
Therapeutic Potential of NAD-Boosting Molecules: The In Vivo Evidence
Can we get NAD+ from food? We can, but not in useful quantities or with sufficient bioavailability.
Supplements, then? Dr. Greger finds the evidence for their usefulness lacking, in interventional trials.
How to boost NAD+, then? Dr. Greger prescribes…
Exercise! It boosts levels by 127% (i.e., it more than doubles the levels), based on a modest three-week exercise bike regimen:
Skeletal muscle NAMPT is induced by exercise in humans
Another study on resistance training found the same 127% boost:

Getting to Neutral – by Trevor Moawad
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 all know that a pessimistic outlook is self-defeating… And yet, toxic positivity can also be a set-up for failure! At some point, reckless faith in the kindly nature of the universe will get crushed, badly. Sometimes that point is a low point in life… sometimes it’s six times a day. But one thing’s for sure: we can’t “just decide everything will go great!” because the world just doesn’t work that way.
That’s where Trevor Moawad comes in. “Getting to neutral” is not a popular selling point. Everyone wants joy, abundance, and high after high. And neutrality itself is often associated with boredom and soullessness. But, Moawad argues, it doesn’t have to be that way.
This book’s goal—which it accomplishes well—is to provide a framework for being a genuine realist. What does that mean?
“I’m not a pessimist; I’m a realist” – every pessimist ever.
^Not that. That’s not what it means. What it means instead is:
- Hope for the best
- Prepare for the worst
- Adapt as you go
…taking care to use past experiences to inform future decisions, but without falling into the trap of thinking that because something happened a certain way before, it always will in the future.
To be rational, in short. Consciously and actively rational.
Feel the highs! Feel the lows! But keep your baseline when actually making decisions.
Bottom line: this book is as much an antidote to pessimism and self-defeat, as it is to reckless optimism and resultant fragility. Highly recommendable.
Click here to check out “Getting to Neutral” and start creating your best, most reason-based life!
PS: in this book, Moawad draws heavily from his own experiences of battling adversity in the form of cancer—of which he died, before this book’s publication. A poignant reminder that he was right: we won’t always get the most positive outcome of any given situation, so what matters the most is making the best use of the time we have.

An Important Way That Love Gets Eroded
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 is unusual for a honeymoon period to last forever, but some relationships fair a lot better than others. Not just in terms of staying together vs separating, but in terms of happiness and satisfaction in the relationship. What’s the secret? There are many, but here’s one of them…
Communication
In this video, the case is made for a specific aspect of communication: airing grievances.
Superficially, this doesn’t seem like a recipe for happiness, but it is one important ingredient—that it’s dangerously easy to let small grievances add up and eat away at one’s love and patience, until one day resentment outweighs attachment, and at that point, it often becomes a case of “checking out before you leave”, remaining in the relationship more due to inertia than volition.
Which, in turn, will likely start to cause resentment on the other side, and eventually things will crumble and/or explode.
In contrast, if we make sure to speak our feelings clearly (10almonds note, not in the video: we think that doing so compassionately is also important), the bad as well as the good, then it means that:
- things don’t stack up and fester (there will less likely be a “final straw” if we are regularly removing straws)
- there is an opportunity for change (in contrast, our partner would be unlikely to adjust anything to correct a problem they don’t know about)
- all but the most inclined-to-anxiety partners can rest easy, because they know that if we had a problem, we’d tell them
This is definitely only one critical aspect of communication; this video for example says nothing about actually being affectionate with one’s partner, or making sure to accept emotional bids for connection (per that story that goes “I knew my marriage was over when he wouldn’t come look at the tomatoes I grew”), but it is one worth considering—even if we at 10almonds would advise being gentle yet honest, and where possible balancing, in aggregate if not in the moment, with positive things (per Gottman’s ratio of 5:1 good moments to bad, being the magic number for marriages that “work”).

Beetroot vs Eggplant – 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 beetroot to eggplant, we picked the beetroot.
Why?
It’s close!
In terms of macros, they’re equal on fiber, while beetroot has slightly more protein and carbs. In both cases, despite being quite firm vegetables when raw, they are nevertheless both mostly water. We’re calling this category a tie.
In the category of vitamins, beetroot has more of vitamins A, B2, B9, and C, while eggplant has more of vitamins B3, B5, B6, E, and K. That’s a marginal victory for eggplant.
When it comes to minerals, however, beetroot has more calcium, copper, iron, magnesium, manganese, phosphorus, potassium, selenium, and zinc, while eggplant is not higher in any minerals. A clear and easy win for beetroot this time.
In terms of polyphenols, both have good-but-different health-giving polyphenols to share, including the quercetin in beetroot and caffeic acid in eggplant—nothing that would tip one ahead of the other, though.
All in all, the categories added up are balanced, but beetroot won the minerals category much more convincingly than eggplant won the vitamins category, so we’re giving this one to beetroot, even if only on tie-breakers!
Of course, enjoy either or both; diversity is good 😎

Ginkgo Biloba, For Memory And, Uh, What Else Again?
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.
Ginkgo biloba, for memory and, uh, what else again?
Ginkgo biloba extract has enjoyed use for thousands of years for an assortment of uses, and has made its way from Traditional Chinese Medicine, to the world supplement market at large. See:
Ginkgo biloba: A Treasure of Functional Phytochemicals with Multimedicinal Applications
But what does the science say about the specific claims?
Antioxidant & anti-inflammatory
We’re going to lump these two qualities together for examination, since one invariably leads to the other.
A quick note: things that have antioxidant and anti-inflammatory properties, often also help guard against cancer and aging. However, in this case, there are few good studies pertaining to anti-aging, and none that we could find pertaining to anti-cancer potential.
So, does it have antioxidant and anti-inflammatory properties, first?
Yes, it has potent antioxidants that do fight inflammation; this is clear, from an abundance of in vitro and in vivo studies, including with human patients:
- Properties of Ginkgo biloba L.: incl. Antioxidant Characterization
- Anti-inflammatory effects of Ginkgo biloba extract against hippocampal neuronal injury
- Gingko biloba-derived lactone prevents osteoarthritis by activating anti-inflammatory signaling pathway
- The anti-inflammatory properties of Ginkgo biloba for the treatment of pulmonary diseases
In short: it helps, and there’s plenty of science for it.
What about anti-aging effects?
For this, there is science, but a lot of the science is not great. As one team of researchers concluded while doing a research review of their own:
❝Based on the reviewed information regarding EGb’s effects in vitro and in vivo, most have reported very positive outcomes with strong statistical analyses, indicating that EGb must have some sort of beneficial effect.
However, information from the reported clinical trials involving EGb are hardly conclusive since many do not include information such as the participant’s age and physical condition, drug doses administered, duration of drug administered as well as suitable control groups for comparison.
We therefore call on clinicians and clinician-scientists to establish a set of standard and reliable standard operating procedure for future clinical studies to properly evaluate EGb’s effects in the healthy and diseased person since it is highly possible it possesses beneficial effects.❞
Translation from sciencese: “These results are great, but come on, please, we are begging you to use more robust methodology”
If you’d like to read the review in question, here it is:
Advances in the Studies of Ginkgo Biloba Leaves Extract on Aging-Related Diseases
Does it have cognitive enhancement effects?
The claims here are generally that it helps:
- improve memory
- improve focus
- reduce cognitive decline
- reduce anxiety and depression
Let’s break these down:
Does it improve memory and cognition?
Ginkgo biloba was quite popular for memory 20+ years ago, and perhaps had an uptick in popularity in the wake of the 1999 movie “Analyze This” in which the protagonist psychiatrist mentions taking ginkgo biloba, because “it helps my memory, and I forget what else”.
Here are a couple of studies from not long after that:
- A double-blind, placebo-controlled, randomized trial of Ginkgo biloba in cognitively intact older adults: neuropsychological findings
- Effects of Ginkgo biloba on mental functioning in healthy volunteers
In short:
- in the first study, it helped in standardized tests of memory and cognition (quite convincing)
- In the second study, it helped in subjective self-reports of mental wellness (also placebo-controlled)
On the other hand, here’s a more recent research review ten years later, that provides measures of memory, executive function and attention in 1132, 534 and 910 participants, respectively. That’s quite a few times more than the individual studies we cited above, by the way. They concluded:
❝We report that G. biloba had no ascertainable positive effects on a range of targeted cognitive functions in healthy individuals❞
Read: Is Ginkgo biloba a cognitive enhancer in healthy individuals? A meta-analysis
Our (10almonds) conclusion: we can’t say either way, on this one.
Does it have neuroprotective effects (i.e., against cognitive decline)?
Yes—probably by the same mechanism will discuss shortly.
- Ginkgo Biloba for Mild Cognitive Impairment and Alzheimer’s Disease: A Systematic Review and Meta-Analysis of Randomized Controlled Trials
- Treatment effects of Ginkgo biloba extract on symptoms of dementia: meta-analysis of randomized controlled trials
Can it help against depression and anxiety?
Yes—but probably indirectly by the mechanism we’ll get to in a moment:
- Role of Ginkgo biloba extract as an adjunctive treatment of elderly patients with depression
- Ginkgo biloba in generalized anxiety disorder and adjustment disorder with anxious mood
Likely this helps by improving blood flow, as illustrated better per:
Efficacy of ginkgo biloba extract as augmentation of venlafaxine in treating post-stroke depression
Which means…
Bonus: improved blood flow
This mechanism may support the other beneficial effects.
See: Ginkgo biloba extract improves coronary blood flow in healthy elderly adults
Is it safe?
Ginkgo biloba extract* is generally recognized as safe.
- However, as it improves blood flow, please don’t take it if you have a bleeding disorder.
- Additionally, it may interact badly with SSRIs, so you might want to avoid it if you’re taking such (despite it having been tested and found beneficial as an adjuvant to citalopram, an SSRI, in one of the studies above).
- No list of possible contraindications can be exhaustive, so please consult your own doctor/pharmacist before taking something new.
*Extract, specifically. The seeds and leaves of this plant are poisonous. Sometimes “all natural” is not better.
Where can I get it?
As ever, we don’t sell it (or anything else), but here’s an example product on Amazon
Enjoy!

Stop Self-Sabotage – by Dr. Judy Ho
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 lot of books of this genre identify one particular kind of self-sabotage, for example, they might pick one out of:
- Bad habits
- Limiting self-beliefs
- Poor goal-setting
- Procrastination
…etc, slap a quick fix on whatever they chose to focus on, and call it a day. Not so with Dr. Ho!
Here we have a much more comprehensive approach to tackling the problem of unintentional self-sabotage. With a multi-vector method, of which all angles can be improved simultaneously, it becomes much less like “whack-a-mole”… And much more like everything actually getting into order and staying that way.
The main approach here is CBT, but far beyond what most pop-psychology CBT books go for, with more techniques and resources.
On which note…
There are many great exercises that Dr. Ho recommends we do while reading… So you might want to get a nice notebook alongside this book if you don’t already have one! And what is more inspiring of optimism than a new notebook?
Bottom line: this is a great, well-organized guide to pruning the “why am I still doing this to myself?” aspects out of your life for a much more intentional, purposeful, effective way of living.
Click here to check it out on Amazon today, and stop sabotaging yourself!
