How Does Alcohol Cause Blackouts?

Sometimes people who have never experienced an alcoholic blackout wonder “is it real, or is it just a convenient excuse to avoid responsibility/embarrassment with regard to things done while drunk?”
In 1969 (so, still in the era of incredibly unethical psychological experiments that ranged from the 50s into the 70s), Dr. Donald Goodwin conducted a study in which intoxicated participants were asked to recall an object they had just seen. Most succeeded initially, but half were unable to remember the object just 30 minutes later, demonstrating alcohol-induced memory blackouts.
But, is it any different from regular forgetting? And the answer is: yes, it is indeed different.
The memories that never got stored
Ethanol, the active compound in alcohol, is lipophilic, enabling it to cross the blood-brain barrier and disrupt brain function. It impairs all kinds of things, including decision-making, impulse control, motor skills, and, notably, memory networks—which is what we’re looking at today.
Memory formation (beyond “working memory”, which is the kind that enables you to have an idea of what you were just doing, and carry out simple plans like “pick up this cup, raise it to my mouth, and take a sip”, without forgetting partway through) relies on a process called long-term potentiation (LTP), which strengthens neural connections to store information. Ethanol disrupts this process, preventing memory storage and causing blackouts.
In effect, this means you didn’t just forget a memory; you never stored it in the first place. For this reason, experiences from during an alcoholic blackout cannot be retrieved in the same ways we might retrieve other memories (e.g. in regular forgetting, it’s possible that a context clue jogs our memory and then we remember the experience—because in regular forgetting, the memory was in there; we just didn’t recall it until we were reminded).
Blackouts (in which the memory is never stored in the first place) typically occur when blood alcohol concentration (BAC) exceeds 0.16, while lower levels can result in partial memory loss (brownouts) in which some things may be recalled, but not others. Factors such as dehydration, genetics, medications, food consumption, and age influence the likelihood of complete blackouts.
While alcohol’s residual effects typically subside within a day, repeated over-drinking can cause permanent neuron damage, as well as of course plenty of damage to other organs in the body (especially the liver and gut).

The Bare-Bones Truth About Osteoporosis
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.
In yesterday’s issue of 10almonds, we asked you “at what age do you think it’s important to start worrying about osteoporosis?”, and here’s the spread of answers you gave us:
The Bare-bones Truth About Osteoporosis
In yesterday’s issue of 10almonds, we asked you “at what age do you think it’s important to start worrying about osteoporosis?”, and here’s the spread of answers you gave us:
At first glance it may seem shocking that a majority of respondents to a poll in a health-focused newsletter think it’ll never be an issue worth worrying about, but in fact this is partly a statistical quirk, because the vote of the strongest “early prevention” crowd was divided between “as a child” and “as a young adult”.
This poll also gave you the option to add a comment with your vote. Many subscribers chose to do so, explaining your choices… But, interestingly, not one single person who voted for “never” had any additional thoughts to add.
We loved reading your replies, by the way, and wish we had room to include them here, because they were very interesting and thought-provoking.
Let’s get to the myths and facts:
Top myth: “you will never need to worry about it; drink a glass of milk and you’ll be fine!”
The body is constantly repairing itself. Its ability to do that declines with age. Until about 35 on average, we can replace bone mineral as quickly as it is lost. After that, we lose it by up to 1% per year, and that rate climbs after 50, and climbs even more steeply for those who go through (untreated) menopause.
Losing 1% per year might not seem like a lot, but if you want to live to 100, there are some unfortunate implications!
About that menopause, by the way… Because declining estrogen levels late in life contribute significantly to osteoporosis, hormone replacement therapy (HRT) may be of value to many for the sake of bone health, never mind the more obvious and commonly-sought benefits.
On the topic of that glass of milk…
- Milk is a great source of calcium, which is useless to the body if you don’t also have good levels of vitamin D and magnesium.
- People’s vitamin D levels tend to directly correlate to the level of sun where they live, if supplementation isn’t undertaken.
- Plant-based milks are usually fortified with vitamin D (and calcium), by the way.
- Most people are deficient in magnesium, because green leafy things don’t form as big a part of most people’s diets as they should.

Next most common myth: “bone health is all about calcium”
We spoke a little above about the importance of vitamin D and magnesium for being able to properly use that. But potassium is also critical:

While we’re on the topic…
People think of collagen as being for skin health. And it is important for that, but collagen’s benefits (and the negative effects of its absence) go much deeper, to include bone health. We’ve written about this before, so rather than take more space today, we’ll just drop the link:

Sesame & Peanut Tofu
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.
Yesterday we learned how to elevate tofu from “nutrition” to “nutritious tasty snack” with our Basic Baked Tofu recipe; today we’re expanding on that, to take it from “nutritious tasty snack” to “very respectable meal”.
You will need
For the tofu:
- The Basic Baked Tofu that we made yesterday (consider making this to be “step zero” of today’s recipe if you don’t already have a portion in the fridge)
For the sauce:
- ⅓ cup peanut butter, ideally with no added sugar or salt (if allergic to peanuts specifically, use almond butter; if allergic to nuts generally, use tahini)
- ¼ bulb garlic, grated or crushed
- 1 tbsp tamarind paste
- 1½ tbsp tamari sauce (or low-sodium soy sauce, if a substitution is necessary)
- 1 tbsp sambal oelek (or sriracha sauce, if a substitution is necessary)
- 1 tsp ground coriander
- 1 tsp ground black pepper
- ½ tsp ground sweet cinnamon
- ½ tsp MSG (or else omit; do not substitute with salt in this case unless you have a particular craving)
- zest of 1 lime
For the vegetables:
- 14 oz broccolini / tenderstem broccoli, thick ends trimmed (failing that, any broccoli)
- 6 oz shelled edamame
- 1½ tsp toasted sesame oil
For serving:
- 4 cups cooked rice (we recommend our Tasty Versatile Rice recipe)
- ½ cup raw cashews, soaked in hot water for at least 5 minutes and then drained (if allergic, substitute cooked chickpeas, rinsed and drained)
- 1 tbsp toasted sesame seeds
- 1 handful chopped cilantro, unless you have the “this tastes like soap” gene, in which case substitute chopped parsley
Method
(we suggest you read everything at least once before doing anything)
1) Combine the sauce ingredients in a bowl and whisk well (or use a blender if you have one that’s comfortable with this relatively small quantity of ingredients). Taste it, and adjust the ingredient ratios if you’d like more saltiness, sweetness, sourness, spiciness, umami.
2) Prepare a bowl with cold water and some ice. Steam the broccolini and edamame for about 3 minutes; as soon as they become tender, dump them into the ice bathe to halt the cooking process. Let them chill for a few minutes, then drain, dry, and toss in the sesame oil.
3) Reheat the tofu if necessary (an air fryer is great for this), and then combine with half of the sauce in a bowl, tossing gently to coat well.
4) Add a little extra water to the remaining sauce, enough to make it pourable, whisking to an even consistency.
5) Assemble; do it per your preference, but we recommend the order: rice, vegetables, tofu, cashews, sauce, sesame seeds, herbs.
Enjoy!

Super Joints – by Pavel Tsatsouline

For those of us for whom mobility and pain-free movement are top priorities, this book has us covered. So what’s different here, compared to your average stretching book?
It’s about functional strength with the stretches. The author’s background as a special forces soldier means that his interest was not in doing arcane yoga positions so much as being able to change direction quickly without losing speed or balance, get thrown down and get back up without injury, twist suddenly without unpleasantly wrenching anything (of one’s own, at least), and generally be able to take knocks without taking damage.
While we are hopefully not having to deal with such violence in our everyday lives, the robustness of body that results from these exercises is one that certainly can go a long way to keep us injury-free.
The exercises themselves are well-described, clearly and succinctly, with equally clear illustrations.
Note: the paperback version is currently expensive, probably due to supply and demand, but if you select the Kindle version, it’s much cheaper with no loss of quality (because the illustrations are black-on-white line-drawings and very clear; perfect for Kindle e-ink)
The style of the book is very casual and conversational, yet somehow doesn’t let that distract it from being incredibly information dense; there is no fluff here, just valuable guidance.
Bottom line: if you would like to be more robust with non-nonsense exercises, then this book is a fine choice.

Healthy Made Simple – by Ella Mills
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.
Often, cookbooks leave a gap between “add the beans to the rice, then microwave” and “delicately embarrass the green-shooted scallions with assiduous garlic before adding to the matelote of orrazata flamed in Sapient Pear Brandy”. This book fills that gap:
It has dishes good for entertaining, and dishes good for eating on a Tuesday night after a long day. Sometimes, they’re even the same dishes.
It has a focus on what’s pleasing, easy, healthy, and consistent with being cooked in a real home kitchen for real people.
The book offers 75 recipes that:
- Take under 30 minutes to make*
- Contain 10 ingredients or fewer
- Have no more than 5 steps
- Are healthy and packed with goodness
- Are delicious and flavorful
*With a selection for under 15 minutes, too!
A strength of the book is that it’s based on practical, real-world cooking, and as such, there are sections such as “Prep-ahead [meals]”, and “cook once, eat twice”, etc.
Just because one is cooking with simple fresh ingredients doesn’t mean that everything bought today must be used today!
Bottom line: if you’d like simple, healthy recipe ideas that lend themselves well to home-cooking and prepping ahead / enjoying leftovers the next day, this is an excellent book for you.

Mythbusting Moldy Food
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.
Most Food Should Not Be Fuzzy
In yesterday’s newsletter, we asked you for your policy when it comes to mold on food (aside from intentional mold, e.g. blue cheese etc), and the responses were interesting:
- About 49% said “throw the whole thing away no matter what it is; it is dangerous”
- About 24% said “cut the mold off and eat the rest of whatever it is”
- The remainder were divided equally between “eat it all; keep the immune system on its toes” and “cut the mold off bread, but moldy animal products are dangerous”
So what does the science say?
Some molds are safe to eat: True or False?
True! We don’t think this is contentious so we’ll not spend much time on it, but just for the sake of being methodical: foods that are supposed to have mold on, including many kinds of cheese and even some kinds of cured meat (salami is an example; that powdery coating is mold).
We could give a big list of safe and unsafe molds, but that would be a list of names and let’s face it, they don’t introduce themselves by name.
However! The litmus test of “is it safe to eat” is:
Did you acquire it with this mold already in place and exactly as expected and advertised?
- If so, it is safe to eat (unless you have an allergy or such)
- If not, it is almost certainly not safe to eat
(more on why, later)
The “sniff test” is a good way to tell if moldy food is bad: True or False?
False. Very false. Because of how the sense of smell works.
You may feel like smell is a way of knowing about something at a distance, but the only way you can smell something is if particles of it are physically connecting with your olfactory receptors inside you. Yes, that has unfortunate implications about bathroom smells, but for now, let’s keep our attention in the kitchen.
If you sniff a moldy item of food, you will now have its mold spores inside your respiratory system. You absolutely do not want them there.
If we cut off the mold, the rest is safe to eat: True or False?
True or False, depending on what it is:
- Hard vegetables (e.g carrots, cabbage), and hard cheeses (e.g. Gruyère, Gouda) – cut off with an inch margin, and it should be safe
- Soft vegetables (e.g. tomatoes, and any vegetables that were hard but are now soft after cooking) – discard entirely; it is unsafe
- Anything else – discard entirely; it is unsafe
The reason for this is because in the case of the hard products mentioned, the mycelium roots of the mold cannot penetrate far.
In the case of the soft products mentioned, the surface mold is “the tip of the iceberg”, and the mycelium roots, which you will not usually be able to see, will penetrate the rest of it.
“Anything else” seems like quite a sweeping statement, but fruits, soft cheeses, yogurt, liquids, jams and jellies, cooked grains and pasta, meats, and yes, bread, are all things where the roots can penetrate deeply and easily. Regardless of you only being able to see a small amount, the whole thing is probably moldy.
The USDA has a handy downloadable factsheet:
Molds On Food: Are They Dangerous?
Eating a little mold is good for the immune system: True or False?
False, generally. There are of course countless types of mold, but not only are many of them pathogenic (mycotoxins), but also, a food that has mold will usually also have pathogenic bacteria along with the mold.
See for example: Occurrence, Toxicity, and Analysis of Major Mycotoxins in Food
Food poisoning will never make you healthier.
But penicillin is safe to eat: True or False?
False, and also penicillin is not the mold on your bread (or other foods).
Penicillin, an antibiotic* molecule, is produced by some species of Penicillium sp., a mold. There are hundreds of known species of Penicillium sp., and most of them are toxic, usually in multiple ways. Take for example:
Penicillium roqueforti PR toxin gene cluster characterization
*it is also not healthy to consume antibiotics unless it is seriously necessary. Antibiotics will wipe out most of your gut’s “good bacteria”, leaving you vulnerable. People have died from C. diff infections for this reason. So obviously, if you really need to take antibiotics, take them as directed, but if not, don’t.
See also: Four Ways Antibiotics Can Kill You
One last thing…
It may be that someone reading this is thinking “I’ve eaten plenty of mold, and I’m fine”. Or perhaps someone you tell about this will say that.
But there are two reasons this logic is flawed:
- Survivorship bias (like people who smoke and live to 102; we just didn’t hear from the 99.9% of people who smoke and die early)
- Being unaware of illness is not being absent of illness. Anyone who’s had an alarming diagnosis of something that started a while ago will know this, of course. It’s also possible to be “low-level ill” often and get used to it as a baseline for health. It doesn’t mean it’s not harmful for you.
Stay safe!

Pulse – by Jenny Chandler
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.
Beans, chickpeas, and lentils are well-established super-healthy foods, but they’re often not a lot of people’s favorite. And why? Usually because of unhappy associations with boring dishes that can barely be called dishes.
This book raises the bar for pulses of various kinds, and not only provides recipes (180 of them) but also guidelines on principles, tips and tricks, what works and what doesn’t, what makes things better or worse, perfect partners, sprouting, and more.
The recipes themselves are not all vegan, nor even all vegetarian, but the beans are the star throughout. For those who are vegan or vegetarian, it’s easy to make substitutions, not least of all because the author is generous with “try this instead of that” and “consider also” suggestions, to help us tailor each dish to our personal preferences, and even the desired vibe of a given meal.
The dishes are neither overly simplistic (it’s not a student survival cookbook, by any means) nor overly complicated; rather, enough is done to make each dish invitingly tasty, and nothing extraneous or pretentious is added for the sake of being fancy. This is about delicious home cooking, nothing more nor less.
If the book has a weakness, it’s that visual learners will feel the absence of pictures for many recipes. But, the text is clear, the instructions are easy to follow, and a photo for each dish would probably have doubled the cost of the book, at least, while halving the number of recipes.
Bottom line: if you’d like to get more beans and other pulses in your diet, but are unsure how to make it exciting, this is an excellent option.
