This is a great title! It’s a great book too, but let’s talk about the title for a moment:
The “Bright Line” referenced (often used in the plural within the book) is the line one draws between what one will and will not do. It’s a line one doesn’t cross, and it’s a bright line, because it’s not a case of “oh woe is me I cannot have the thing”, but rather “oh yay is me for I being joyously healthy”.
And as for living happy, thin, and free? The author makes clear that “thin” is only a laudable goal if it’s bookended by “happy” and “free”. Eating things because we want to, and being happy about our choices.
To this end, while some of the book is about nutrition (and for example the strong recommendation to make the first “bright lines” one draws cutting out sugar and flour), the majority of it is about the psychology of eating.
This includes, hunger and satiety, willpower and lack thereof, disordered eating and addictions, body image issues and social considerations, the works. She realizes and explains, that if being healthy were just a matter of the right diet plan, everyone would be healthy. But it’s not; our eating behaviors don’t exist in a vacuum, and there’s a lot more to consider.
Despite all the odds, however, this is a cheerful and uplifting book throughout, while dispensing very practical, well-evidenced methods for getting your brain to get your body to do what you want it to.
Bottom line: this isn’t your average diet book, and it’s not just a motivational pep talk either. It’s an enjoyable read that’s also full of science and can make a huge difference to how you see food.

An Unexpected Extra Threat Of Alcohol
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 Could Use Some Exotic Booze…
…then for health reasons, we’re going to have to say “nay”.
We’ve written about alcohol before, and needless to say, it’s not good:
(the answer is “no, we cannot”)
In fact, the WHO (which unlike government regulatory bodies setting “safe” limits on drinking, makes no profit from taxes on alcohol sales) has declared that “the only safe amount of alcohol is zero”:
WHO: No level of alcohol consumption is safe for our health
Up there, where the air is rarefied…
If you’re flying somewhere this summer (Sinatra-style flying honeymoon or otherwise), you might want to skip the alcohol even if you normally do imbibe, because:
❝…even in young and healthy individuals, the combination of alcohol intake with sleeping under hypobaric conditions poses a considerable strain on the cardiac system and might lead to exacerbation of symptoms in patients with cardiac or pulmonary diseases.
These effects might be even greater in older people; cardiovascular symptoms have a prevalence of 7% of inflight medical emergencies, with cardiac arrest causing 58% of aircraft diversions.❞
Source: Alcohol plus cabin pressure at higher altitude may threaten sleeping plane passengers’ heart health
The experiment divided subjects into a control group and a study group; the study group were placed in simulated cabin pressure as though at altitude, which found, when giving some of them two small(we’re talking the kind given on flights) alcoholic drinks:
❝The combination of alcohol and simulated cabin pressure at cruising altitude prompted a fall in SpO2 to an average of just over 85% and a compensatory increase in heart rate to an average of nearly 88 beats/minute during sleep.❞
In contrast, that was 77 beats/minute for those who had alcohol but weren’t at altitude pressure, or 64 beats/minute for those who neither drank nor were at altitude pressure.
Lots more metrics were recorded and the study is interesting to read; if you’ve ever slept on a plane and thought “that sleep was not restful at all”, then know: it wasn’t just the seat’s fault, nor the engine, nor the recycled nature of the air—it was the reduced pressure causing hypoxia (defined as having oxygen levels lower than the healthy clinical norm of 90%) and almost halving your sleep’s effectiveness for a less than 10% drop in available oxygen in the blood (the sleepers not at altitude pressure averaged 96% SpO2, compared to the 85% at altitude).
We say “almost halving” because the deep sleep phase of sleep was reduced from 84 minutes (control) to 67.5 minutes at altitude without alcohol, or 46.5 minutes at altitude with alcohol.
Again, this was a pressure cabin in a lab—so this wasn’t about the other conditions of an airplane (seats, engine hundreds of other people, etc).
Which means: in an actual airplane it’s probably even worse.
Oh, and the study participants? All healthy individuals aged 18–40, so again probably worse for those older (or younger) than that range, or with existing health conditions!

Prevention Is Better Than Cure

Preventative healthcare is the theme this week:
New year, new risks
The start of a new year is a great time to update adult vaccinations, including the flu shot, any COVID-19 boosters, and vaccines for pneumonia, shingles, and tetanus—when was your last booster, after all? Vaccination recommendations vary by age and health conditions, so do check what’s appropriate in your case. Key vaccines include the pneumonia vaccine for those 65 and older, the shingles vaccine for adults over 50, and the Tdap vaccine every 10 years to protect against tetanus, diphtheria, and pertussis (whooping cough), especially for new parents and grandparents, to protect infants:

The heart-healthiest swap you can do
Based on a large (n=202,863, of which 160,123 women and 42,740 men) dataset, a higher plant-to-animal protein ratio is associated with significantly lower risks of cardiovascular disease (CVD) and coronary artery disease (CAD), with diets lower in meat (especially if lower in red meat) and instead rich in plant-based proteins like legumes, nuts, and whole grains reducing CVD risk by 19% and coronary artery disease risk by 27%. Which is quite considerable.
Substituting even small amounts of animal protein (especially if it’s red meat) with plant protein further enhances heart health:

Let’s keep pan-resistant superbugs at bay
Researchers want to warn us about the threat of pan-resistant bacteria, which could render all known antibiotics ineffective, leading to a sharp rise in global infection-related deaths.
To be clear, we don’t have anything pan-resistant yet, but antibiotic-resistant superbugs are getting close, and in the long term, are likely to win the evolutionary arms race if we don’t change things to diverge considerably from our current path. Modeling a hypothetical pan-resistant E. coli strain, researchers predicted U.S. sepsis deaths could increase 18- to 46-fold within five years of its emergence.
The study calls for urgent action, including stricter antibiotic stewardship, new drug development, and monitoring technologies, emphasizing that without intervention, the global impact could be catastrophic:

The Herbal Supplement That Rivals Prozac
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.
Flower Power: St. John’s Wort’s Drug-Level Effectiveness
St. John’s wort is a small yellow flower, extract of which can be bought inexpensively off-the-shelf in pretty much any pharmacy in most places.
It’s sold and used as a herbal mood-brightener.
Does it work?
Yes! It’s actually very effective. This is really uncontroversial, so we’ll keep it brief.
The main findings of studies are that St. John’s wort not only gives significant benefits over placebo, but also works about as well as prescription anti-depressants:
A systematic review of St. John’s wort for major depressive disorder
They also found that fewer people stop taking it, compared to how many stop taking antidepressants. It’s not known how much of this is because of its inexpensive, freely-accessible nature, and how much might be because it gave them fewer adverse side effects:
Clinical use of Hypericum perforatum (St John’s wort) in depression: A meta-analysis
How does it work?
First and foremost, it’s an SSRI—a selective serotonin reuptake inhibitor. Basically, it doesn’t add serotonin, but it makes whatever serotonin you have, last longer. Same as most prescription antidepressants. It also affects adenosine and GABA pathways, which in lay terms, means it promotes feelings of relaxation, in a similar way to many prescription antianxiety medications.
Mechanism of action of St John’s wort in depression: what is known?
Any problems we should know about?
Yes, definitely. To quote directly from the National Center for Complementary and Integrative Health:
St. John’s wort can weaken the effects of many medicines, including crucially important medicines such as:
- Antidepressants
- Birth control pills
- Cyclosporine, which prevents the body from rejecting transplanted organs
- Some heart medications, including digoxin and ivabradine
- Some HIV drugs, including indinavir and nevirapine
- Some cancer medications, including irinotecan and imatinib
- Warfarin, an anticoagulant (blood thinner)
- Certain statins, including simvastatin
I’ve read all that, and want to try it!
As ever, we don’t sell it (or anything else), but here’s an example product on Amazon.
Please be safe and do check with your doctor and/or pharmacist, though!

Walnut, Apricot, & Sage Nut Roast
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 important to have at least one good nut roast recipe in your repertoire. It’s something that’s very good for making a good dish out of odds and ends that are in your house, and done well, it’s not only filling and nutritious, but a tasty treat too. Done badly, everyone knows the results can be unfortunate… Making this the perfect way to show off your skills!
You will need
- 1 cup walnuts
- ½ cup almonds
- ¼ cup whole mixed seeds (chia, pumpkin, & poppy are great)
- ¼ cup ground flax (also called flax meal)
- 1 medium onion, finely chopped
- 1 large carrot, grated
- 4 oz dried apricots, chopped
- 3 oz mushrooms, chopped
- 1 oz dried goji berries
- ½ bulb garlic, crushed
- 2 tbsp fresh sage, chopped
- 1 tbsp nutritional yeast
- 2 tsp dried rosemary
- 2 tsp dried thyme
- 2 tsp black pepper, coarse ground
- 1 tsp yeast extract (even if you don’t like it; trust us; it will work) dissolved in ¼ cup hot water
- ½ tsp MSG or 1 tsp low-sodium salt
- Extra virgin olive oil
Method
(we suggest you read everything at least once before doing anything)
1) Preheat the oven to 350℉ / 180℃, and line a 2 lb loaf tin with baking paper.
2) Heat some oil in a skillet over a moderate heat, and fry the onion for a few minutes until translucent. Add the garlic, carrot, and mushrooms, cooking for another 5 minutes, stirring well. Set aside to cool a little once done.
3) Process the nuts in a food processor, pulsing until they are well-chopped but not so much that they turn into flour.
4) Combine the nuts, vegetables, and all the other ingredients in a big bowl, and mix thoroughly. If it doesn’t have enough structural integrity to be thick and sticky and somewhat standing up by itself if you shape it, add more ground flax. If it is too dry, add a little water but be sparing.
5) Spoon the mixture into the loaf tin, press down well (or else it will break upon removal), cover with foil and bake for 30 minutes. Remove the foil, and bake for a further 15 minutes, until firm and golden. When done, allow it to rest in the tin for a further 15 minutes, before turning it out.
6) Serve, as part of a roast dinner (roast potatoes, vegetables, gravy, etc).
Enjoy!

Healthy Brain, Happy Life – by Dr. Wendy Suzuki
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 talked about Dr. Wendy Suzuki’s research in the category of exercise and brain-benefits in our main feature the other day. But she has more to say than we can fit into an article!
This book chronicles her discoveries, through her work in memory and neuroplasticity, to her discoveries about exercise, and her dive into broader neurology-based mental health. So what does neurology-based mental health look like?
The answer is: mitigating brain-busters such as stress and anxiety, revitalizing a fatigued brain, boosting creativity, and other such benefits.
Does she argue that exercise is a cure-all? No, not quite. Sometimes there are other things she’s recommending (such as in her chapter on challenging the neurobiology of the stress response, or her chapter on meditation and the brain).
The writing style is mostly casual, interspersed with occasional mini-lectures (complete with diagrams and other illustrations), and is very readable and informative throughout.
Bottom line: if you’d like the more in-depth details of Dr. Suzuki’s work, this book is a very accessible way to get 320 pages of that!

Dark Calories – by Dr. Catherine Shanahan

You may be wondering: do we really need a 416-page book to say “don’t use vegetable oils”?
The author, who was a biochemist before becoming a family physician, takes a lot of care to explain in ways the non-chemists amongst us can understand (with molecular diagrams very well-labelled), exactly why certain seed/vegetable oils (both of those names being imprecise and unhelpful as umbrella terms) cause metabolic problems for us, when in contrast olive oil, avocado oil, and even peanut oil, do not.
Understanding is, for many, the root foundation of compliance. We are more likely to abide by rules we understand the logic behind, than seemingly arbitrary “thou shalt not…” proclamations.
So that’s an important strength of the book, demystifying various fats and how our body responds to them on a biochemical level, not just “is associated with such-and-such, based on observational population studies”. This kind of explanation clears up why, for example, seed oils correlate with obesity more than calories, sugar, wheat, or beef—having as it does to do with affecting our body’s ability to generate and use energy.
She also offers practical tips/reminders throughout, such as how “organic” does not necessarily mean “healthy” (indeed, many poisonous plants can be grown “organically”), and nor does “organic” mean “unrefined”, it speaks only for the conditions in which the raw product was first made, before other things were done to it later.
We learn a lot, too, about the processes of oxidation, the biochemistry behind that (more diagrams!), and of course the inflammatory response to same (an important factor in most if not all chronic disease).
The style is mostly very easy-to-read pop-science, though if you’re not a chemist, you’ll probably need to slow down for the biochemistry explanations (this reviewer certainly did).
Bottom line: this is more than just a litany against vegetable oils; it’s a ground-upwards education in metabolic biochemistry for the layperson, and what that means for us in terms of chronic disease risks.
