Eat More (Of This) For Lower Blood Pressure
Heart disease remains the world’s #1 killer. We’d say “and in the US, it’s no different”, but in fact, the US is #1 country for heart disease. So, it’s worse and perhaps some extra care is in order.
But how?
What matters the most
Is it salt? Salt plays a part, but it’s not even close to the top problem:
Hypertension: Factors Far More Relevant Than Salt
Is it saturated fat? Saturated fat from certain sources plays more of a role than salt, but other sources may not be so much of an issue:
Can Saturated Fats Be Heart-Healthy?
Is it red meat? Red meat is not great for the heart (or for almost anything else, except perhaps anemia):
The Whys and Hows of Cutting Meats Out Of Your Diet
…but it’s still not the top dietary factor.
The thing many don’t eat
All the above are foodstuffs that a person wanting a healthier heart and cardiovascular system in general might (reasonably and usually correctly) want to cut down, but there’s one thing that most people need more of:
Why You’re Probably Not Getting Enough Fiber (And How To Fix It)
And this is especially true for heart health:
❝Dietary fiber has emerged as a crucial yet underappreciated part of hypertension management.
Our comprehensive analysis emphasizes the evidence supporting the effectiveness of dietary fiber in lowering blood pressure and reducing the risk of cardiovascular events.❞
Specifically, she and her team found:
- Each additional 5g of fiber per day reduces blood pressure by 2.8/2.1 (systolic/diastolic, in mmHG)
- Dietary fiber works in several ways to improve cardiovascular health, including via gut bacteria, improved lipids profiles, and anti-inflammatory effects
- Most people are still only getting a small fraction (¼ to ⅓) of the recommended daily amount of fiber. To realize how bad that is, imagine if you consumed only ¼ of the recommended daily amount of calories every day!

The Vagus Nerve’s Power for Weight Loss
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. Arun Dhir is a university lecturer, a gastrointestinal surgeon, an author, and a yoga and meditation instructor, and he has this to say:
Gut feelings
The vagus nerve is the 10th cranial nerve, also known as “vagus” (“the wanderer”), because it travels from the brain to many other body parts, including the ears, throat, heart, respiratory system, gut, pancreas, liver, and reproductive system. It’s no surprise then, that it plays a key role in brain-gut communication and metabolism regulation.
The vagus nerve is part of the parasympathetic nervous system, responsible for rest, digestion, and counteracting the stress response. Most signals through the vagus nerve travel from the gut to the brain, though there is communication in both directions.
You may be beginning to see how this works and its implications for weight management: the vagus nerve senses metabolites from the liver, pancreas, and small intestine, and regulates insulin production by stimulating beta cells in the pancreas, which is important for avoiding/managing insulin resistance and metabolic syndrome in general.
Dr. Dhir cites a study in which vagus nerve stimulation (originally used for treating epilepsy and depression) was shown to cause unintentional weight loss (6-11%) in patients, revealing a link to weight management. Of course, that is quite a specific sample, so more research is needed to say for sure, but because the principle is very sound and the mechanism of action is clear, it’s not being viewed as a controversial conclusion.
As for how get these benefits, here are seven ways:
- Cold water on the face: submerge your face in cold water in the morning while holding water in your mouth, or cover your face with a cold wet washcloth (while holding your breath please; no need to waterboard yourself!), which activates the “mammalian dive response” in which your body activates the parasympathetic nervous system in order to remain calm and thus survive for longer underwater
- Alternate hot and cold showers: switch between hot and cold water during showers for 10-second intervals; this creates eustress and activates the process of hormesis, improving your overall stress management and reducing any chronic stress response you may otherwise have going on
- Humming and gargling: the vibrations in the throat stimulate the nearby vagus nerve
- Deep breathing (pranayama): yoga breathing exercises, especially combined with somatic exercises such as the sun salutation, can stimulate the vagus nerve
- Intermittent fasting: helps recalibrate the metabolism and indirectly improves vagus nerve function
- Massage and acupressure: stimulates lymphatic channels and the vagus nerve
- Long walks in nature (“forest bathing”): helps trigger relaxation in general

Healthy Butternut Macaroni Cheese
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 comfort food classic, healthy and plant-based, without skimping on the comfort.
You will need
- ½ butternut squash, peeled and cut into small pieces (if buying ready-chopped, this should be about 1 lb)
- 1 onion, chopped
- ¼ bulb garlic
- 2 tbsp extra virgin olive oil
- 12 oz (or thereabouts) wholegrain macaroni, or similar pasta shape (even penne works fine—which is good, as it’s often easier to buy wholegrain penne than wholegrain macaroni) (substitute with a gluten-free pasta such as buckwheat pasta, if avoiding gluten)
- 6 oz (or thereabouts) cashews, soaked in hot water for at least 15 minutes (but longer is better)
- ½ cup milk (your preference what kind; we recommend hazelnut for its mellow nutty flavor)
- 3 tbsp nutritional yeast
- Juice of ½ lemon
- 2 tsp black pepper, coarse ground
- ½ tsp MSG, or 1 tsp low-sodium salt
- Optional: smoked paprika, to serve
Note: if you are allergic to nuts, please accept our apologies that there’s no substitution available in this one. Simply put, removing the cashews would mean changing most of the rest of the recipe to compensate, so there’s no easy “or substitute with…” that we can mention. We’ll have to find/develop a good healthy plant-based no-nuts recipe for you at a later date.
Method
(we suggest you read everything at least once before doing anything)
1) Preheat the oven to 400℉ / 200℃.
2) Combine the butternut squash, onion, and garlic with the olive oil, in a large roasting tin, tossing thoroughly to ensure an even coat of oil. Roast them for about 25 minutes until soft.
3) Cook the macaroni while you wait (this should take about 10 minutes or so in salted water), drain, and rinse thoroughly in cold water, before setting aside. This cooling increases the pasta’s resistant starch content (that’s good, for your gut and for your blood sugars, and thus also for your heart and brain), and it will maintain this benefit even when we reheat it later.
4) Drain the cashews, and tip them into a high-speed blender with the milk, and process until smooth. Add the roasted vegetables and the remaining ingredients apart from the pasta, and continue to process until again smooth. You can add a little more milk if you need to, but go easy with it.
5) Heat the sauce (that you just made in the food processor) gently in a saucepan, and refresh the pasta by pouring a kettle of boiling water through it in a colander.
6) Optional: combine the pasta and sauce in an ovenproof dish or cast iron pan, and give it a few minutes under the hottest grill (or browning iron, if you have such) your oven can muster. Alternatively, use a culinary blowtorch, if you have one.
7) Serve; and if you didn’t do the optional step above, this means combining the pasta and sauce. You can also dust the top with some extra seasonings if you like. Smoked paprika works well for this.
Enjoy!

Gut Health for Women – by Aurora Bloom
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 things first: though the title says “For Women”, almost all of it applies to men too—and the things that don’t apply, don’t cause a problem. So if you’re cooking for your family that contains one or more men, this is still great.
Bloom gives us a good, simple, practical introduction to gut health. Her overview also covers gut-related ailments beyond the obvious “tummy hurts”. On which note:
A very valuable section of this book covers dealing with any stomach-upsets that do occur… without harming your trillions of tiny friends (friendly gut microbiota). This alone can make a big difference!
The book does of course also cover the things you’d most expect: things to eat or avoid. But it goes beyond that, looking at optimizing and maintaining your gut health. It’s not just dietary advice here, because the gut affects—and is affected by—other lifestyle factors too. Ranges from mindful eating, to a synchronous sleep schedule, to what kinds of exercise are best to keep your gut ticking over nicely.
There’s also a two-week meal plan, and an extensive appendix of resources, not to mention a lengthy bibliography for sourcing health claims (and suggesting further reading).
In short, a fine and well-written guide to optimizing your gut health and enjoying the benefits.

Death by Sitting – by Carolyne Thompson
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.
You may be wondering: is this a lot of words to say “sit down less”?
And the answer is: there’s a lot more in here than that. Of course, yes, “sit down less” is an important take-away, but there’s a lot about the specific problems caused by sitting in chairs, the health risks are that are increased and how, and the early warning signs to watch out for.
After these chapters of woe, most of the book is given over to solutions; about taking standing and walking breaks, tying movement to productivity, why exercise alone is not enough to offset the damage of sitting, relearning ergonomic posture in the context of mitigating the harm, psychological shifts to break the habit of sitting, redefining social norms around sitting and socializing, rewiring one’s body and retraining better movements as well as postures to always immediately move out of if one finds oneself in, and much much more.
The style is light and easy to read, while still including scientific research as appropriate along with practical, actionable advice.
Bottom line: if you’d like to do better for your body than slowly killing it for however many hours a day, then this book has a wealth of advice far beyond the obvious (but important!) “sit less”.

Calculate (And Enjoy) The Perfect Night’s Sleep
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 Dr. Michael Breus, a clinical psychologist and sleep specialist, and he wants you to get a good night’s sleep, every night.
First, let’s assume you know a lot of good advice about how to do that already in terms of environment and preparation, etc. If you want a recap before proceeding, then we recommend:
Get Better Sleep: Beyond The Basics
Now, what does he want to add?
Wake up refreshed
Of course, how obtainable this is will depend on the previous night’s sleep, but there is something important we can do here regardless, and it’s: beat sleep inertia.
Sleep inertia is what happens when we wake up groggy (for reasons other than being ill, drugged, etc) rather than refreshed. It’s not actually related to how much sleep we have, though!
Rather, it pertains to whether we woke up during a sleep cycle, or between cycles:
- If we wake up between sleep cycles, we’ll avoid sleep inertia.
- If we wake up during a sleep cycle, we’ll be groggy.
Deep sleep generally occurs in 90-minute blocks, albeit secretly that is generally 3× 20 minute blocks in a trenchcoat, with transition periods between, during which the brainwaves change frequency.
REM sleep generally occurs in 20 minute blocks, and will usually arrive in series towards the end of our natural sleep period, to fit neatly into the last 90-minute cycle.
Sometimes these will appear a little out of order, because we are complicated organic beings, but those are the general trends.
In any case, the take-away here is: interrupt them at your peril. You need to wake up between cycles. There are two ways you can do this:
- Carefully calculate everything, and set a very precise alarm clock (this will work so long as you are correct in guessing how long it will take you to fall asleep)
- Use a “sunrise” lamp alarm clock, that in the hour approaching your set alarm time, will gradually increase the light. Because the body will not naturally wake up during a cycle unless a threat is perceived (loud noise, physical rousing, etc), the sunrise lamp method means that you will wake up between sleep cycles at some point during that hour (towards the beginning or end, depending on what your sleep balance/debt is like).
Do not sleep in (even if you have a sleep debt); it will throw everything out.
Caffeine will not help much in the morning
Assuming you got a reasonable night’s sleep, your brain has been cleansed of adenosine (a sleepy chemical), and if you are suffering from sleep inertia, the grogginess is due to melatonin (a different sleepy chemical).
Caffeine is an adenosine receptor blocker, so that will do nothing to mitigate the effects of melatonin in your brain that doesn’t have any meaningful quantity of adenosine in it in the morning.
Adenosine gradually accumulates in the brain over the course of the day (and then gets washed out while we sleep), so if you’re sleepy in the afternoon (for reasons other than: you just had a nap and now have sleep inertia again), then caffeine can block that adenosine in the afternoon.
Of course, caffeine is also a stimulant (it increases adrenaline levels and promotes vasoconstriction), but its effects at healthily small doses are modest for most people, and you’d do better by splashing cold water on your face and/or listening to some upbeat music.
Learn more: The Two Sides Of Caffeine
Time your naps correctly (if you take naps)
Dr. Breus has a lot to say about this, based on a lot of clinical research, but as it’s entirely consistent with what we’ve written before (based on the exact same research), to save space we’ll link to that here:
How To Be An Expert Nap-Artist (With No “Sleep-Hangovers”)
Calculate your bedtime correctly
Remember what we said about sleep cycles? This means that that famous “7–9 hours sleep” is actually “either 7½ or 9 hours sleep”—because those are multiples of 90 minutes, whereas 8 hours (for example) is not.
So, consider the time you want to get up (ideally, this should be relatively early, and the same time every day), and then count backwards either 7½ or 9 hours sleep (you choose), add 20–30 minutes to fall asleep, and that’s your bedtime.
So for example: if you want to have 7½ hours sleep and get up at 6am, then your bedtime is anywhere between 10pm and 10:10pm.
Remember how we said not to sleep in, even if you have a sleep debt? Now is the time to pay it off, if you have one. If you normally sleep 7½ hours, then make tonight a 9-hour sleep (plus 20–30 minutes to fall asleep). This means you’ll still get up at 6am, but your bedtime is now anywhere between 8:30pm and 8:40pm.

Their First Baby Came With Medical Debt. These Illinois Parents Won’t Have Another.
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.
JACKSONVILLE, Ill. — Heather Crivilare was a month from her due date when she was rushed to an operating room for an emergency cesarean section.
The first-time mother, a high school teacher in rural Illinois, had developed high blood pressure, a sometimes life-threatening condition in pregnancy that prompted doctors to hospitalize her. Then Crivilare’s blood pressure spiked, and the baby’s heart rate dropped. “It was terrifying,” Crivilare said.
She gave birth to a healthy daughter. What followed, though, was another ordeal: thousands of dollars in medical debt that sent Crivilare and her husband scrambling for nearly a year to keep collectors at bay.
The Crivilares would eventually get on nine payment plans as they juggled close to $5,000 in bills.
“It really felt like a full-time job some days,” Crivilare recalled. “Getting the baby down to sleep and then getting on the phone. I’d set up one payment plan, and then a new bill would come that afternoon. And I’d have to set up another one.”
Crivilare’s pregnancy may have been more dramatic than most. But for millions of new parents, medical debt is now as much a hallmark of having children as long nights and dirty diapers.
About 12% of the 100 million U.S. adults with health care debt attribute at least some of it to pregnancy or childbirth, according to a KFF poll.
These people are more likely to report they’ve had to take on extra work, change their living situation, or make other sacrifices.
Overall, women between 18 and 35 who have had a baby in the past year and a half are twice as likely to have medical debt as women of the same age who haven’t given birth recently, other KFF research conducted for this project found.
“You feel bad for the patient because you know that they want the best for their pregnancy,” said Eilean Attwood, a Rhode Island OB-GYN who said she routinely sees pregnant women anxious about going into debt.
“So often, they may be coming to the office or the hospital with preexisting debt from school, from other financial pressures of starting adult life,” Attwood said. “They are having to make real choices, and what those real choices may entail can include the choice to not get certain services or medications or what may be needed for the care of themselves or their fetus.”
Best-Laid Plans
Crivilare and her husband, Andrew, also a teacher, anticipated some of the costs.
The young couple settled in Jacksonville, in part because the farming community less than two hours north of St. Louis was the kind of place two public school teachers could afford a house. They saved aggressively. They bought life insurance.
And before Crivilare got pregnant in 2021, they enrolled in the most robust health insurance plan they could, paying higher premiums to minimize their deductible and out-of-pocket costs.
Then, two months before their baby was due, Crivilare learned she had developed preeclampsia. Her pregnancy would no longer be routine. Crivilare was put on blood pressure medication, and doctors at the local hospital recommended bed rest at a larger medical center in Springfield, about 35 miles away.
“I remember thinking when they insisted that I ride an ambulance from Jacksonville to Springfield … ‘I’m never going to financially recover from this,’” she said. “‘But I want my baby to be OK.’”
For weeks, Crivilare remained in the hospital alone as covid protocols limited visitors. Meanwhile, doctors steadily upped her medications while monitoring the fetus. It was, she said, “the scariest month of my life.”
Fear turned to relief after her daughter, Rita, was born. The baby was small and had to spend nearly two weeks in the neonatal intensive care unit. But there were no complications. “We were incredibly lucky,” Crivilare said.
When she and Rita finally came home, a stack of medical bills awaited. One was already past due.
Crivilare rushed to set up payment plans with the hospitals in Jacksonville and Springfield, as well as the anesthesiologist, the surgeon, and the labs. Some providers demanded hundreds of dollars a month. Some settled for monthly payments of $20 or $25. Some pushed Crivilare to apply for new credit cards to pay the bills.
“It was a blur of just being on the phone constantly with all the different people collecting money,” she recalled. “That was a nightmare.”
Big Bills, Big Consequences
The Crivilares’ bills weren’t unusual. Parents with private health coverage now face on average more than $3,000 in medical bills related to a pregnancy and childbirth that aren’t covered by insurance, researchers at the University of Michigan found.
Out-of-pocket costs are even higher for families with a newborn who needs to stay in a neonatal ICU, averaging $5,000. And for 1 in 11 of these families, medical bills related to pregnancy and childbirth exceed $10,000, the researchers found.
“This forces very difficult trade-offs for families,” said Michelle Moniz, a University of Michigan OB-GYN who worked on the study. “Even though they have insurance, they still have these very high bills.”
Nationwide polls suggest millions of these families end up in debt, with sometimes devastating consequences.
About three-quarters of U.S. adults with debt related to pregnancy or childbirth have cut spending on food, clothing, or other essentials, KFF polling found.
About half have put off buying a home or delayed their own or their children’s education.
These burdens have spurred calls to limit what families must pay out-of-pocket for medical care related to pregnancy and childbirth.
In Massachusetts, state Sen. Cindy Friedman has proposed legislation to exempt all these bills from copays, deductibles, and other cost sharing. This would parallel federal rules that require health plans to cover recommended preventive services like annual physicals without cost sharing for patients. “We want … healthy children, and that starts with healthy mothers,” Friedman said. Massachusetts health insurers have warned the proposal will raise costs, but an independent state analysis estimated the bill would add only $1.24 to monthly insurance premiums.
Tough Lessons
For her part, Crivilare said she wishes new parents could catch their breath before paying down medical debt.
“No one is in the right frame of mind to deal with that when they have a new baby,” she said, noting that college graduates get such a break. “When I graduated with my college degree, it was like: ‘Hey, new adult, it’s going to take you six months to kind of figure out your life, so we’ll give you this six-month grace period before your student loans kick in and you can get a job.’”
Rita is now 2. The family scraped by on their payment plans, retiring the medical debt within a year, with help from Crivilare’s side job selling resources for teachers online.
But they are now back in debt, after Rita’s recurrent ear infections required surgery last year, leaving the family with thousands of dollars in new medical bills.
Crivilare said the stress has made her think twice about seeing a doctor, even for Rita. And, she added, she and her husband have decided their family is complete.
“It’s not for us to have another child,” she said. “I just hope that we can put some of these big bills behind us and give [Rita] the life that we want to give her.”
About This Project
“Diagnosis: Debt” is a reporting partnership between KFF Health News and NPR exploring the scale, impact, and causes of medical debt in America.
The series draws on original polling by KFF, court records, federal data on hospital finances, contracts obtained through public records requests, data on international health systems, and a yearlong investigation into the financial assistance and collection policies of more than 500 hospitals across the country.
Additional research was conducted by the Urban Institute, which analyzed credit bureau and other demographic data on poverty, race, and health status for KFF Health News to explore where medical debt is concentrated in the U.S. and what factors are associated with high debt levels.
The JPMorgan Chase Institute analyzed records from a sampling of Chase credit card holders to look at how customers’ balances may be affected by major medical expenses. And the CED Project, a Denver nonprofit, worked with KFF Health News on a survey of its clients to explore links between medical debt and housing instability.
KFF Health News journalists worked with KFF public opinion researchers to design and analyze the “KFF Health Care Debt Survey.” The survey was conducted Feb. 25 through March 20, 2022, online and via telephone, in English and Spanish, among a nationally representative sample of 2,375 U.S. adults, including 1,292 adults with current health care debt and 382 adults who had health care debt in the past five years. The margin of sampling error is plus or minus 3 percentage points for the full sample and 3 percentage points for those with current debt. For results based on subgroups, the margin of sampling error may be higher.
Reporters from KFF Health News and NPR also conducted hundreds of interviews with patients across the country; spoke with physicians, health industry leaders, consumer advocates, debt lawyers, and researchers; and reviewed scores of studies and surveys about medical debt.
KFF Health News is a national newsroom that produces in-depth journalism about health issues and is one of the core operating programs at KFF—an independent source of health policy research, polling, and journalism. Learn more about KFF.
