First things first: it’s a great book, and it’s this reviewer’s favorite of Dr. Greger’s so far (for posterity: it’s just been published and this reviewer has just finished reading the copy she got on pre-order)
Unlike many popular physician authors, Dr. Greger doesn’t rehash a lot of old material, and instead favours prioritizing new material in each work. Where appropriate, he’ll send the reader to other books for more specific information (e.g: you want to know how to avoid premature death? Go read How Not To Die. You want to know how to lose weight? How Not To Diet. Etc).
In the category of new information, he has a lot to offer here. And with over 8,000 references, it’s information, not conjecture. On which note, we recommend the e-book version if that’s possible for you, for three reasons:
- It’s possible to just click the references and be taken straight to the cited paper itself online
- To try to keep the book’s size down, Dr. Greger has linked to other external resources too
- The only negative reviews on Amazon, so far, are people complaining that the print copy’s text is smaller than they’d like
For all its information-density (those 8,000+ references are packed into 600ish pages), the book is very readable even to a lay reader; the author is a very skilled writer.
As for the content, we can’t fit more than a few sentences here so forgive the brevity, but we’ll mention that he covers:
- Slowing 11 pathways of aging
- The optimal anti-aging regimen according to current best science
- Preserving function (specific individual aspects of aging, e.g. hearing, sight, cognitive function, sexual function, hair, bones, etc)
- “Dr. Greger’s Anti-Aging Eight”
In terms of “flavor” of anti-aging science, his approach can be summed up as: diet and lifestyle as foundation; specific supplements and interventions as cornerstones.
Bottom line: this is now the anti-aging book.

The Sweetener That Interferes With Hunger/Satiety Signals
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.
Non-sugar sweeteners came under fire from the World Health Organization a couple of years ago:
The Problem With Sweeteners ← this is mostly about how they prompt cravings of increasingly sweeter foods/drinks, but there are other considerations discussed too
And sucralose (which is technically a sugar, but isn’t processed by the body as sugar, so it “doesn’t count” as such; the body treats it as a dietary fiber instead) got some bad press of its own:
The Sucralose News: Scaremongering Or Serious? ← the answer is both, by the way, but there’s nuance here, so do read the article!
And now, there’s more news about how sucralose specifically interferes with the brain’s hunger/satiety signals:
The study
A medium-sized (n=75) study of adults looked at the brain’s responses to, varyingly,
- Water
- Sucralose in water
- Sucrose in water (matched to be the same sweetness as the sucralose)
…using MRI, focusing on hunger-related regions like the hypothalamus.
Additionally, blood samples were taken to measure glucose, insulin, and satiety hormone (GLP-1) levels.
As for what they found:
- Sucralose kept hunger signals active in the brain for up to 35 minutes, unlike sucrose, which reduced hunger activity quickly.
- There was increased hypothalamic blood flow after sucralose intake, which meant heightened hunger signaling.
- Participants felt hungrier after consuming sucralose compared to sugar
- Sugar intake increased blood glucose (obviously), suppressing hunger, whereas sucralose had no such effect (again, reasonable, though it was worth checking, because if sucralose had an effect on insulin response, that would indirectly affect blood sugar levels one way or the other, depending on the effect on insulin levels—but that didn’t happen, so for now we may assume sucralose doesn’t affect insulin or insulin signalling).
- Women exhibited twice the hypothalamic response to sucralose compared to men, reinforcing sex-based differences in appetite control. Specifically, it was most likely hormonal differences that drove this, since the study’s participants were young adults (ages 18–35); it’s possible that if older adults had been included, untreated menopause could have changed these stats. But that latter’s just a hypothesis for now.
- Sucralose enhanced brain connectivity between the hypothalamus and motivation/reward-processing areas, potentially increasing cravings.
You can read the paper itself here:
The practical takeaway? Sucralose interferes with the brain’s “full” signals, keeping you hungrier for longer, which will (all else being equal) incline you to eat more than you would otherwise.
So, it might be worth skipping sucralose, unless you specifically want to increase how much you eat.

How extreme heat can affect you—and how you can protect yourself
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.
Because of climate change, last summer was the hottest in the Northern Hemisphere in 2,000 years—and this summer is expected to be even hotter. The record may continue to be broken: Extreme heat is expected to become even more frequent.
The scorching heat has led to an increase in heat-related deaths in the United States, according to the Department of Health and Human Services, with approximately 2,300 deaths in the summer of 2023. Extreme heat, defined as a period of two to three days with high heat and humidity with temperatures above 90 degrees Fahrenheit, can have serious health consequences, including symptoms like headache, dizziness, loss of consciousness, nausea, and confusion.
As we face more extreme heat, you may be wondering how you can protect yourself and your loved ones. Read on to learn about heat-related illness, who’s most at risk, and more.
What happens when our bodies are exposed to extreme heat?
As our body temperature rises, our bodies attempt to cool down by opening up more blood vessels near the skin to begin sweating. The evaporation of our sweat regulates our body temperature, but it also leads to losing fluids and minerals.
When it’s too humid, sweating alone doesn’t do the trick. The heart must work harder to bring blood around the body. It starts beating faster, which can cause light-headedness, nausea, and headache.
This process can affect our health in different ways, including increasing our risk of hospitalization for heart disease, worsening asthma, and injuring kidneys due to dehydration. It can also result in heat-related illness. Below are some effects of heat on our bodies:
- Heat cramps: Occur when a person loses salt through sweating, which causes painful cramps. Symptoms begin as painful spasms after heavy sweating, usually in the legs or the stomach. Heat cramps can lead to heat exhaustion or heat stroke.
- Heat exhaustion: This occurs when the body loses an excessive amount of water and salt, usually during intense physical activity. Symptoms include irritability, heavy sweating, and weakness, including muscle cramps. Heat exhaustion can lead to heat stroke.
- Heat stroke: This is the most severe heat-related illness. It happens when the body can’t cool down and reaches a temperature of 106 Fahrenheit or higher within 10 to 15 minutes. If the person doesn’t receive emergency treatment, it can cause permanent disability or death. Symptoms include confusion, loss of consciousness, and seizures.
What should I do if someone experiences a heat-related illness?
If you or someone you’re with begins to show signs of heat illness, the Centers for Disease Control and Prevention recommends the following:
- Heat cramps: Stop all physical activity, drink water or a sports drink, move to a cool place, and wait for cramps to go away before resuming activity. If the cramps last more than an hour, you’re on a low-sodium diet, or you have heart problems, get medical help.
- Heat exhaustion: Move the person to a cool place, loosen their clothes, use a cool bath or cloths to try to lower their body temperature, and give them a sip of water. If the person throws up, or if their symptoms last longer than an hour or worsen, get medical help.
- Heat stroke: Call 911 immediately. Then, move the person to a cooler place, use cool cloths or a cool bath to help lower their temperature, and don’t give them anything to drink.
Read more about heat-related illness and what to do in each case.
Who’s more vulnerable to extreme heat?
While everyone can be affected by extreme heat, some people are more at risk, including people of color.
A 2023 KFF report outlined that because of historical residential segregation in the U.S. (known as “redlining”), people of color are more likely to live in areas that experience higher temperatures from rooftops, asphalt, and sidewalks that retain the sun’s heat (known as the “urban heat island effect”). Additionally, communities of color are more likely to live in areas with fewer trees, which act as a canopy and provide shade, making the heat worse and more direct.
Children under 5, adults 65 or over, and pregnant people are also more vulnerable to extreme heat. If you have a chronic health condition like diabetes, heart problems, or a mental health condition, you’re also at higher risk. (Some psychiatric medications, like antidepressants, can also make people more susceptible to heat).
Lastly, anyone exposed to the sun and extreme heat for long periods is also at higher risk. This includes athletes, people who work outdoors, and unhoused people.
What can I do to prevent heat-related illness during a heat wave?
During a heat wave, follow these tips to stay cool and protect yourself from heat-related illness:
- Never leave your pets or children inside a car.
- Wear loose, light-colored clothing (dark colors absorb more heat).
- Find shade if you’re outside.
- If you don’t have air conditioning in your home, go to a place where you can cool down, such as a local library, community center, local pool or splash pad, or mall. Check to see if your city has designated cooling centers. (Cities like New York have a list of places.)
- Wear a hat.
- Drink (non-alcoholic) fluids often to stay hydrated—and if you have pets, give them water frequently as well.
- Check on your family members or older neighbors who may be more sensitive to extreme heat.
- Avoid using your stove or oven too often or during the hottest parts of the day.
- Cover your windows with shades to keep the heat out.
What are some resources to prevent heat-related illness?
If you need financial assistance to cool down your home, such as to purchase an air conditioner, apply to the federal government’s Low Income Home Energy Assistance Program.
Before you head outside during a heat wave, use the CDC’s HeatRisk tool: Enter your zip code to find the current heat risk in your area and get tips on what to do to stay safe with each risk level.
During a heat wave, also look for a cooling center in your state using the National Center for Healthy Housing’s list.
Check out the National Weather Service’s for more tips and resources.

Bold Beans – by Amelia Christie-Miller
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 beans are one of the most healthful foods around, but how to include more of them, without getting boring?
This book has the answer, giving 80 exciting recipes, divided into the following sections:
- Speedy beans
- Bean snacks & sharing plates
- Brothy beans
- Bean bowls
- Hearty salads
- Bean feasts
The recipes are obviously all bean-centric, though if you have a particular dietary restriction, watch out for the warning labels on some (e.g. meat, fish, dairy, gluten, etc), and make a substitution if appropriate.
The recipes themselves have a happily short introductory paragraph, followed by all you’d expect from a recipe book (ingredients, measurements, method, picture)
There’s also a reference section, to learn about different kinds of beans and bean-related culinary methods that can be applied per your preferences.
Bottom line: if you’d like to include more beans in your daily diet but are stuck for making them varied and interesting, this is the book for you!

Is there anything good about menopause? Yep, here are 4 things to look forward to
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.
Menopause is having a bit of a moment, with less stigma and more awareness about the changes it can bring.
A recent senate inquiry recommended public education about perimenopause and menopause, more affordable treatments and flexible work arrangements.
But like many things in life the experiences of menopause are on a continuum. While some women find it challenging and require support, others experience some physical and emotional benefits. These are rarely reported – but we can learn from the research available and, importantly, from people’s lived experiences.
Here are four changes to look forward to once you reach menopause.
Insta_Photos/Shutterstock 1. No more periods or related issues
Menopause is considered “complete” 12 months after the final period of a woman (or person assigned female at birth) who previously menstruated.
Perhaps unsurprisingly, the benefit at the top of the list is no more periods (unless you are taking hormone therapy and still have your womb). This can be particularly beneficial for women who have had to manage erratic, unpredictable and heavy bleeding.
At last, you don’t need to keep sanitary protection in every bag “just in case”. No more planning where the bathroom is or having to take extra clothes. And you’ll save money by not purchasing sanitary products.
There is also good news for women who have had heavy bleeding due to uterine fibroids – common benign gynaecological tumours that affect up to 80% of women. The evidence suggests hormonal changes (for women not taking hormone therapy) can lead to a reduction in the size of fibroids and relieve symptoms.
Women who suffer from menstrual migraine may experience an improvement in migraines post-menopause as their hormonal fluctuations begin to settle – but the timeframe for this remains unclear.
For some women, no more periods also means more participation in social activities from which they may have been excluded due to periods. For example, religious activities or food preparation in some cultures.
2. Getting your body and your groove back
Throughout their reproductive lives, women in heterosexual relationships are usually the ones expected to be proactive about preventing pregnancy.
Some post-menopausal women describe a re-emergence of their sexuality and a sense of sexual freedom that they had not previously experienced (despite contraceptive availability) as there is no longer a risk of pregnancy.
A participant in my research into women’s experiences of menopause described the joy of no longer being child-bearing age:
I’ve got a body back for me, you know, coz I can’t get pregnant, not that I haven’t enjoyed having [children] and things like that and it was a decision to get pregnant but I feel like, ooh my body isn’t for anybody now but me, people, you know?
For women who have chosen to be child-free there may also be a sense of freedom from social expectations. People will likely stop asking them when they are planning to have children.
3. A new chapter and a time to focus on yourself
Another participant described menopause as an unexpected “acceleration point” for change.
Women told us they were more accepting of themselves and their needs rather than being focused on the needs of other people. Researchers have previously tracked this shift from “living for others” to “a life of one’s own”.
Some women find the strength of emotions at this time a challenge, whereas others find their potency can facilitate liberation – enabling them to speak their minds or be more assertive than at any other time in their lives.
4. Increased self-confidence
A new sense of liberation can fuel increased self-confidence at menopause. This has been reported in studies based on in-depth interviews with women.
Confidence boosts can coincide with changes in career and sometimes in relationships as priorities and self-advocacy transform.
Life on the other side
It can be hard to think about what is good about menopause, particularly if you are having challenges during perimenopause – but these can get better with time.
In cultures where women are valued as they become older, women describe themselves as positively contributing to the community. They find they gain power and respect as they age.
We need to work towards more positive societal attitudes on this front. Our bodies change across the lifespan and are remarkable at every stage, including menopause.

Spinach vs Vine Leaves – 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 spinach to vine leaves, we picked the vine leaves.
Why?
Granted, they’re not available in most supermarkets, but if you live not too far from a wine-growing region, then they’ll be available at markets, and certainly stuffed vine leaves are thing found in many restaurants (though those are usually saltier than you’d make them at home—restaurants make most of their money from selling you drinks, after all, not the food). So, it’s worth noting the simple nutritional values if you prepare your own food:
In terms of macros, the most relevant difference is that vine leaves have about 5x the fiber. They’re also higher in carbs, but the overall glycemic index is lower in any case, so that’s not an issue. An easy win for vine leaves here.
Looking at vitamins, spinach has more of vitamins B1, B9, K, and choline, while vine leaves have more of vitamins A, B2, B3, B5, B6, B7, and C. Another win for vine leaves.
When it comes to minerals, spinach has more iron, potassium, and selenium, while vine leaves have more calcium, copper, magnesium, manganese, and phosphorus. One more win for vine leaves.
In terms of phytochemicals, spinach has a much higher oxalate content (that’s not a problem for most people, but bad if you have certain kidney issues).
Adding up the sections, it’s a clear overall win for vine leaves; by all means enjoy either or both though, unless you have kidney problems, of course!

Eat to Beat Disease – by Dr. William Li
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. William Li asks the important question: is your diet feeding disease, or defeating it?
Because everything we put in our bodies makes our health just a little better—or just a little worse. Ok, sometimes a lot worse.
But for most people, when it comes to diet, it’s a death of a thousand cuts of unhealthy food. And that’s what he looks to fix with this book.
The good news: Dr. Li (while not advocating for unhealthy eating, of course), focuses less on what to restrict, and more on what to include. This book covers hundreds of such healthy foods, and ideas (practical, useful ones!) on incorporating them daily, including dozens of recipes.
He mainly looks at five ways our food can help us with…
- Angiogenesis (blood vessel replacement)
- Regeneration (of various bodily organs and systems)
- Microbiome health (and all of its knock-on effects)
- DNA protection (and thus slower cellular aging)
- Immunity (defending the body while also reducing autoimmune problems)
The style is simple and explanatory; Dr. Li is a great educator. Reading this isn’t a difficult read, but you’ll come out of it feeling like you just did a short course in health science.
Bottom line: if you’d like an easy way to improve your health in an ongoing and sustainable way, then this book can help you do just that.
