❝Loved the info on nuts; of course I always eat pecans, which didn’t make the list of healthy nuts!❞
Dear subscriber, pardon the paraphrase of your comment—somehow it got deleted and now exists only in this writer’s memory. However, to address it:
Pecans are great too! We can’t include everything in every article (indeed, we got another feedback the same day saying the article was too long), but we love when you come to us with stuff for us to look at and write about (seriously, writer here: the more you ask, the easier it makes my job), so let’s talk pecans for a moment:
Pecans would have been number six on our list if we’d have written more!
Like many nuts, they’ve an abundance of healthy fats, fiber, vitamins, and minerals.
They’re particularly good for zinc, which is vital for immune function, healing (including normal recovery after normal exercise), and DNA synthesis (so: anti-aging).
Pecans are also great for reducing LDL (“bad” cholesterol) and triglycerides (which are also bad for heart health); check it out:

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

The Paleo Diet
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.
What’s The Real Deal With The Paleo Diet?
The Paleo diet is popular, and has some compelling arguments for it.
Detractors, meanwhile, have derided Paleo’s inclusion of modern innovations, and have also claimed it’s bad for the heart.
But where does the science stand?
First: what is it?
The Paleo diet looks to recreate the diet of the Paleolithic era—in terms of nutrients, anyway. So for example, you’re perfectly welcome to use modern cooking techniques and enjoy foods that aren’t from your immediate locale. Just, not foods that weren’t a thing yet. To give a general idea:
Paleo includes:
- Meat and animal fats
- Eggs
- Fruits and vegetables
- Nuts and seeds
- Herbs and spices
Paleo excludes:
- Processed foods
- Dairy products
- Refined sugar
- Grains of any kind
- Legumes, including any beans or peas
Enjoyers of the Mediterranean Diet or the DASH heart-healthy diet, or those with a keen interest in nutritional science in general, may notice they went off a bit with those last couple of items at the end there, by excluding things that scientific consensus holds should be making up a substantial portion of our daily diet.
But let’s break it down…
First thing: is it accurate?
Well, aside from the modern cooking techniques, the global market of goods, and the fact it does include food that didn’t exist yet (most fruits and vegetables in their modern form are the result of agricultural engineering a mere few thousand years ago, especially in the Americas)…
…no, no it isn’t. Best current scientific consensus is that in the Paleolithic we ate mostly plants, with about 3% of our diet coming from animal-based foods. Much like most modern apes.
Ok, so it’s not historically accurate. No biggie, we’re pragmatists. Is it healthy, though?
Well, health involves a lot of factors, so that depends on what you have in mind. But for example, it can be good for weight loss, almost certainly because of cutting out refined sugar and, by virtue of cutting out all grains, that means having cut out refined flour products, too:
Diet Review: Paleo Diet for Weight Loss
Measured head-to-head with the Mediterranean diet for all-cause mortality and specific mortality, it performed better than the control (Standard American Diet, or “SAD”), probably for the same reasons we just mentioned. However, it was outperformed by the Mediterranean Diet:
So in lay terms: the Paleo is definitely better than just eating lots of refined foods and sugar and stuff, but it’s still not as good as the Mediterranean Diet.
What about some of the health risk claims? Are they true or false?
A common knee-jerk criticism of the paleo-diet is that it’s heart-unhealthy. So much red meat, saturated fat, and no grains and legumes.
The science agrees.
For example, a recent study on long-term adherence to the Paleo diet concluded:
❝Results indicate long-term adherence is associated with different gut microbiota and increased serum trimethylamine-N-oxide (TMAO), a gut-derived metabolite associated with cardiovascular disease. A variety of fiber components, including whole grain sources may be required to maintain gut and cardiovascular health.❞
Bottom line:
The Paleo Diet is an interesting concept, and certainly can be good for short-term weight loss. In the long-term, however (and: especially for our heart health) we need less meat and more grains and legumes.

Dealing with Thirst!

Busting The Myth of “Eight Glasses Of Water A Day”
Everyone knows we must drink 8 glasses of water a day, or else we’re going to get a failing grade at being a healthy human—like not flossing, or not using adequate sunscreen.
But… Do we? And does tea count? How about (we dare but whisper it) coffee? And soda drinks are mostly water, right? But aren’t some drinks dehydrating? Are special electrolyte drinks really better? There are so many things to consider, so many differing advices, and it’s easy to give up, or just choose what to believe in as a leap of faith.
A quick brain-teaser for you first, though:
If coffee and soda don’t count because they’re dehydrating, then what if you were to take:
– A concentrated tiny cup of espresso, and then a glass of water, would the glass of water count?
– Or (we don’t relish the thought) what if you took a spoonful of soda syrup, and then a glass of water, would the glass of water count?
If your answer was “yes, it’s a glass of water”, then why would it not count if it were taken all at once (e.g. as an Americano coffee, or a regular soda)?
If your answer was “yes, but that water might only offset the dehydration caused by the coffee/syrup, so I might only be breaking even”, then you were thinking about this the right way:
How much water you need depends on many factors that can be affected by what else you are consuming and what else you are doing. Science loves averages, so eight glasses a day may be great if you are of average health, and average body size, in a temperate climate, doing moderate exercise, and so on and so on.
If you’re not the most average person of all time? You may need to take into account a lot of factors, ranging from what you ate for dinner to how much you perspired during your morning exercises. As you (probably) don’t live in laboratory conditions, this can become an impossible task—and if you missed (or guessed incorrectly) even one factor, the whole calculation will be thrown off. But is there any other way to know?
What of the infamous pee test? Drink enough to make your urine as clear as possible, and if it’s dark, you’re dehydrated, common wisdom says.
In reality, however, that tells you not what’s in your body, but rather, what got ejected from your body. If your urine is dark, it might mean you had too little water, but it also could just mean you had the right amount of water but too much sodium, for instance. A study of this was done on athletes, and found no correlation between urine color and actual bodily hydration when measured directly via a blood test.
So, if we can’t just have an app tell us “drink this many glasses of water”, and we can’t trust urine color, what can we do?
What we can do is trust that our body comes with (for free!) a wonderful homeostatic system and it will try to correct any imbalances. If you are thirsty, you’re dehydrated. Drink something with plenty of water in, if not plain water.
But what about special electrolyte drinks? If you need salts, you will crave them. Craving a salty snack? Go for it! Or if you prefer not to snack, do a salt lick test (just put a little salt on your finger, and taste it; if it tastes good, wait a minute or two, and then have a little more, and repeat until it doesn’t).
Bonus Tip:
- Make sure you always have a source of hydration (that you enjoy!) to hand. Maybe it’s chilled water, maybe it’s a pot of tea, maybe it’s a sports drink, it doesn’t matter too much. Even coffee is actually fine, by the way (but don’t overdo it).
- Make a personal rule: “I will always make time for hydration”. That means, if you’re thirsty, have something with water in it now. Not when you’ve finished what you’re doing (unless you really can’t stop, because you are a racecar driver mid-race, or a surgeon mid-operation, or something), but now. Do not postpone it until after you’ve done some other thing first; you will forget and it will keep getting postponed. Always make time for water.

Women’s Strength Training Anatomy – by Frédéric Delavier
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.
Fitness guides for women tend to differ from fitness guides for men, in the wrong ways:
“Do some squats and jumping jacks, and here’s a exercise for your abs; you too can look like our model here”
In those other books we are left wonder: where’s the underlying information? Where are the explanations that aren’t condescending? Where, dare we ask, is the understanding that a woman might ever lift something heavier than a baby?
Delavier, in contrast, delivers. With 130 pages of detailed anatomical diagrams for all kinds of exercises to genuinely craft your body the way you want it for you. Bigger here, smaller there, functional strength, you decide.
And rest assured: no, you won’t end up looking like Arnold Schwarzenegger unless you not only eat like him, but also have his genes (and possibly his, uh, “supplement” regime).
What you will get though, is a deep understanding of how to tailor your exercise routine to actually deliver the personalized and specific results that you want.

Are You Eating AGEs?
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 Trouble of the AGEs
Advanced Glycation End-Products (AGEs) are the result of the chemical process of glycation, which can occur in your body in response to certain foods you ate, or you can consume them directly, if you eat animal products that contained them (because we’re not special and other animals glycate too, especially mammals such as pigs, cows, and sheep).
As a double-whammy, if you cook animal products (especially without water, such as by roasting or frying), extra AGEs will form during cooking.
When proteinous and/or fatty food turns yellow/golden/brown during cooking, that’s generally glycation.
If there’s starch present, some or all of that yellow/golden/brown stuff will be a Maillard Reaction Product (MRP), such as acrylamide. That’s not exactly a health food, but it’s nowhere near being even in the same ballpark of badness.
In short, during cooking:
- Proteinous/fatty food turns yellow/golden/brown = probably an AGE
- Starchy food turns yellow/golden/brown = probably a MRP
The AGEs are far worse.
What’s so bad about AGEs?
Let’s do a quick tour of some studies:
- The role of advanced glycation end-products in retinal ageing and disease
- Advanced glycation end-products and their circulating receptors predict cardiovascular disease mortality in older women
- Elevated serum advanced glycation end-products in obese indicate risk for the metabolic syndrome: a link between healthy and unhealthy obesity?
- Increased levels of serum advanced glycation end-products in women with polycystic ovary syndrome
- Advanced glycation end-products and their involvement in liver disease
- Effects of advanced glycation end-products on renal fibrosis and oxidative stress
- Role of advanced glycation end-products and oxidative stress in vascular complications in diabetes
- Cancer malignancy is enhanced by advanced glycation end-products
- Advanced glycation end-products in the pathogenesis of Alzheimer’s disease
We could keep going, but you probably get the picture!
What should we do about it?
There are three main ways to reduce serum AGE levels:
Reduce or eliminate consumption of animal products
Especially mammalian animal products, such as from pigs, cows, and sheep, especially their meat. Processed versions are even worse! So, steak is bad, but bacon and sausages are literally top-tier bad.
Cook wet
Dry cooking (which includes frying, and especially includes deep fat frying, which is worse than shallow frying which is worse than air frying) produces far more AGEs than cooking with methods that involve water (boiling, steaming, slow-cooking, etc).
As a bonus, adding acidic ingredients (e.g. vinegar, lemon juice, tomato juice) can halve the amount of AGEs produced.
Consume antioxidants
Our body does have some ability to deal with AGEs, but that ability has its limits, and our body can be easily overwhelmed if we consume foods that are bad for it. So hopefully you’ll tend towards a plant-based diet, but whether you do or don’t:
You can give your body a hand by consuming antioxidant foods and drinks (such as berries, tea/coffee, and chocolate), and/or taking supplements.

The Gut-Healthiest Yogurt
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.
Not only is this yogurt, so it’s winning from the start with its probiotic goodness, but also it’s full of several kinds of fiber, and gut-healthy polyphenols too. Plus, it’s delicious. The perfect breakfast, but don’t let us stop you from enjoying it at any time of day!
You will need
- 1 cup yogurt with minimal additives. Live Greek yogurt is a top-tier choice, and plant-based varieties are fine too (just watch out, again, for needless additives)
- 7 dried figs, roughly chopped
- 6 fresh figs, thinly sliced
- 5 oz chopped pitted dates
- 4 tbsp mixed seeds (pumpkin, sunflower, and chia are a great combination)
Method
(we suggest you read everything at least once before doing anything)
1) Soak the dried figs, the dates, and half the seeds in hot water for at least 5 minutes. Drain (be careful not to lose the chia seeds) and put in a blender with ¼ cup cold water.
2) Blend the ingredients from the last step into a purée (you can add a little more cold water if it needs it).
3) Mix this purée into the yogurt in a bowl, and add in the remaining seeds, mixing them in thoroughly.
4) Top with the sliced figs, and serve (or refrigerate, up to a few days, until needed).
Enjoy!
