Pomegranate Peel’s Potent Potential
Pomegranates have been enjoying a new surge in popularity in some parts, widely touted for their health benefits. What’s not so widely touted is that most of the bioactive compounds that give these benefits are concentrated in the peel, which most people in most places throw away.
They do exist in the fruit too! But if you’re discarding the peel, you’re missing out:
Food Applications and Potential Health Benefits of Pomegranate and its Derivatives
“That peel is difficult and not fun to eat though”
Indeed. Drying the peel, especially freeze-drying it, is a good first step:
❝Freeze drying peels had a positive effect on the total phenolic, tannins and flavonoid than oven drying at all temperature range. Moreover, freeze drying had a positive impact on the +catechin, -epicatechin, hesperidin and rutin concentrations of fruit peel. ❞
Once it is freeze-dried, it is easy to grind it into a powder for use as a nutritional supplement.
“How useful is it?”
Studies with 500mg and 1000mg per day in people with cases of obesity and/or type 2 diabetes saw significant improvements in assorted biomarkers of cardiometabolic health, including blood pressure, blood sugar levels, cholesterol, and hemoglobin A1C:
- Effects of pomegranate extract supplementation on inflammation in overweight and obese individuals: A randomized controlled clinical trial
- Beneficial effects of pomegranate peel extract on plasma lipid profile, fatty acids levels and blood pressure in patients with diabetes mellitus type-2: A randomized, double-blind, placebo-controlled study
It also has anticancer properties:
- Punicalagin, a polyphenol from pomegranate fruit, induces growth inhibition and apoptosis in human PC-3 and LNCaP cells
- Punica granatum (Pomegranate) activity in health promotion and cancer prevention
- The extract from Punica granatum (pomegranate) peel induces apoptosis and impairs metastasis in prostate cancer cells
…and neuroprotective benefits:
- Long-term (15 mo) dietary supplementation with pomegranates attenuates cognitive and behavioral deficits
- Neuroprotective Effects of Pomegranate Peel Extract
- An Evaluation of the Effects of a Non-caffeinated Energy Dietary Supplement on Cognitive and Physical Performance
…and it may protect against osteopenia and osteoporosis, but we only have animal or in vitro studies so far, for example:
- Pomegranate Peel Extract Prevents Bone Loss in a Preclinical Model of Osteoporosis and Stimulates Osteoblastic Differentiation in Vitro
- Pomegranate and its derivatives can improve bone health through decreased inflammation and oxidative stress in an animal model of postmenopausal osteoporosis
Want to try it?
We don’t sell it, but you can buy pomegranates at your local supermarket, or buy the peel extract ready-made from online sources; here’s an example on Amazon for your convenience
(the marketing there is for use of the 100% pomegranate peel powder as a face mask; it also has health benefits for the skin when applied topically, but we didn’t have time to cover that today)
Enjoy!

Calm Your Inflammation – by Dr. Brenda Tidwell
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.
The book starts with an overview of inflammation, both acute and chronic, before diving into how to reduce the latter kind (acute inflammation being usually necessary and helpful, usually fighting disease rather than creating it).
The advice in the book is not just dietary, and covers lifestyle interventions too, including exercise etc—and how to strike the right balance, since the wrong kind of exercise or too much of it can sabotage our efforts. Similarly, Dr. Tidwell doesn’t just say such things as “manage stress” but also provides 10 ways of doing so, and so forth for other vectors of inflammation-control. She does cover dietary things as well though, including supplements where applicable, and the role of gut health, sleep, and other factors.
The style of the book is quite entry-level pop-science, designed to be readable and comprehensible to all, without unduly dumbing-down. In terms of hard science or jargon, there are 6 pages of bibliography and 3 pages of glossary, so it’s neither devoid of such nor overwhelmed by it.
Bottom line: if fighting inflammation is a priority for you, then this book is an excellent primer.

The Science-Backed Anti-Inflammatory Diet for Beginners – by Dr. Yasmine Elamir & Dr. William Grist
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 written about how to eat to beat inflammation, but what we didn’t do is include 75 recipes and a plan for building up one’s culinary repertoire around those core dishes!
That’s what this book does. It covers briefly the science of inflammation and anti-inflammatory diet, discusses experimental elimination diets (e.g. you eliminate likely culprits of triggering your inflammation, then reintroduce them one by one to see which it was), and ingredients likely to increase or decrease inflammation.
The 75 recipes are good, and/but a caveat is “yes, one of the recipes is ketchup and another is sour cream” so it’s not exactly 75 mains.
However! Where this book excels is in producing anti-inflammatory versions of commonly inflammatory dishes. That ketchup? Not sugary. The sour cream? Vegan. And so forth. We also see crispy roast potatoes, an array of desserts, and sections for popular holiday dishes too, so you will not need to be suddenly inflamed into the next dimension when it comes to festive eating.
The recipes are what the title claims them to be, “science-backed anti-inflammatory”, and that is clearly the main criterion for their inclusion. They are not by default vegan, vegetarian, dairy-free, nut-free, gluten-free, etc. For this reason, all recipes are marked with such tags as “V, VG, DF, GF, EF, NF” etc as applicable.
Bottom line: we’d consider this book more of a jumping-off point than a complete repertoire, but it’s a very good jumping-off point, and will definitely get you “up and running” (there’s a 21-day meal plan, for example).

How To Avoid Age-Related Macular Degeneration
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.
Avoiding Age-Related Macular Degeneration
Eye problems can strike at any age, but as we get older, it becomes a lot more likely. In particular, age-related macular degeneration is, as the name suggests, an age-bound disease.
Is there no escaping it, then?
The risk factors for age-related macular degeneration are as follows:
- Being over the age of 55 (can’t do much about this one)
- Being over the age of 65 (risk climbs sharply now)
- Having a genetic predisposition (can’t do much about this one)
- Having high cholesterol (this one we can tackle)
- Having cardiovascular disease (this one we can tackle)
- Smoking (so, just don’t)
Genes predispose; they don’t predetermine. Or to put it another way: genes load the gun, but lifestyle pulls the trigger.
Preventative interventions against age-related macular degeneration
Prevention is better than a cure in general, and this especially goes for things like age-related macular degeneration, because the most common form of it has no known cure.
So first, look after your heart (because your heart feeds your eyes).
See also: The Mediterranean Diet
Next, eat to feed your eyes specifically. There’s a lot of research to show that lutein helps avoid age-related diseases in the eyes and the rest of the brain, too:
See also: Brain Food? The Eyes Have It
Do supplements help?
They can! There was a multiple-part landmark study by the National Eye Institute, a formula was developed that reduced the 5-year risk of intermediate disease progressing to late disease by 25–30%. It also reduced the risk of vision loss by 19%.
You can read about both parts of the study here:
Age-Related Eye Disease Studies (AREDS/AREDS2): major findings
As you can see, an improvement was made between the initial study and the second one, by replacing beta-carotene with lutein and zeaxanthin.
The AREDS2 formula contains:
- 500 mg vitamin C
- 180 mg vitamin E
- 80 mg zinc
- 10 mg lutein
- 2 mg copper
You can learn more about these supplements, and where to get them, here on the NEI’s corner of the official NIH website:

Intermittent Fasting In Women
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’s Q&A Day at 10almonds!
Have a question or a request? We love to hear from you!
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
❝Does intermittent fasting differ for women, and if so, how?❞
For the sake of layout, we’ve put a shortened version of this question here, but the actual wording was as below, and merits sharing in full for context
Went down a rabbit hole on your site and now can’t remember how I got to the “Fasting Without Crashing” article on intermittent fasting so responding to this email lol, but was curious what you find/know about fasting for women specifically? It’s tough for me to sift through and find legitimate studies done on the results of fasting in women, knowing that our bodies are significantly different from men. This came up when discussing with my sister about how I’ve been enjoying fasting 1-2 days/week. She said she wanted more reliable sources of info that that’s good, since she’s read more about how temporary starvation can lead to long-term weight gain due to our bodies feeling the need to store fat. I’ve also read about that, but also that fasting enables more focused autophagy in our bodies, which helps with long-term staving off of diseases/ailments. Curious to know what you all think!
~ 10almonds subscriber
So, first of all, great question! Thanks for asking it
Next up, isn’t it strange? Books come in the format:
- [title]
- [title, for women]
You would not think women are a little over half of the world’s population!
Anyway, there has been some research done on the difference of intermittent fasting in women, but not much.
For example, here’s a study that looked at 1–2 days/week IF, in other words, exactly what you’ve been doing. And, they did have an equal number of men and women in the study… And then didn’t write down whether this made a difference or not! They recorded a lot of data, but neglected to note down who got what per sex:
Here’s a more helpful study, that looked at just women, and concluded:
❝In conclusion, intermittent fasting could be a nutritional strategy to decrease fat mass and increase jumping performance.
However, longer duration programs would be necessary to determine whether other parameters of muscle performance could be positively affected by IF. ❞
~ Dr. Martínez-Rodríguez et al.
Those were “active women”; another study looked at just women who were overweight or obese (we realize that “active women” and “obese or overweight women” is a Venn diagram with some overlap, but still, the different focus is interesting), and concluded:
❝IER is as effective as CER with regard to weight loss, insulin sensitivity and other health biomarkers, and may be offered as an alternative equivalent to CER for weight loss and reducing disease risk.❞
As for your sister’s specific concern about yo-yoing, we couldn’t find studies for this yet, but anecdotally and based on books on Intermittent Fasting, this is not usually an issue people find with IF. This is assumed to be for exactly the reason you mention, the increased cellular apoptosis and autophagy—increasing cellular turnover is very much the opposite of storing fat!
You might, by the way, like Dr. Mindy Pelz’s “Fast Like A Girl”, which we reviewed previously

Foam Rolling – by Karina Inkster
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’ve ever bought a foam roller only to place it under your lower back once and then put it somewhere for safekeeping and never use it again, this book will help fix that.
Karina Inkster (what a cool name) is a personal trainer, and the book also features tips and advice from physiotherapists and sports medicine specialist doctors too, so all bases are well and truly covered.
This is not, in case you’re wondering, a book that could have been a pamphlet, with photos of the exercises and one-liner explanation and that’s it. Rather, Inkster takes us through the anatomy and physiology of what’s going on, so that we can actually use this thing correctly and get actual noticeable improvements to our health from it—as promised in the subtitle’s mention of “for massage, injury prevention, and core strength”. To be clear, a lot of it is also about soft tissue mobilization, and keeping our fascia healthy (an oft-underestimated aspect of general mobility).
We would mention that since the photos are pleasantly colorful (like those on the cover) and this adds to the clarity, we’d recommend springing for the (quite inexpensive) physical copy, rather than a Kindle edition (if your e-reader is a monochrome e-ink device like this reviewer’s, anyway).
Bottom line: this book will enable your foam roller to make a difference to your life.

Almonds vs Cashews – 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 almonds to cashews, we picked the almonds.
Why?
Both are great! But here’s why we picked the almonds:
In terms of macros, almonds have a little more protein and more than 4x the fiber. Given how critical fiber is to good health, and how most people in industrialized countries in general (and N. America in particular) aren’t getting enough, we consider this a major win for almonds.
Things are closer to even for vitamins, but almonds have a slight edge. Almonds are higher in vitamins A, B2, B3, B9, and especially 27x higher in vitamin E, while cashews are higher in vitamins B1, B5, B6, C & K. So, a moderate win for almonds.
In the category of minerals, cashews do a bit better on average. Cashews have moderately more copper, iron, phosphorus, selenium, and zinc, while almonds boast 6x more calcium, and slightly more manganese and potassium. We say this one’s a slight win for cashews.
Adding the categories up, however, makes it clear that almonds win the day.
However, of course, enjoy both! Diversity is healthy. Just, if you’re going to choose between them, we recommend almonds.
