Is chocolate milk a good recovery drink after a workout? A dietitian reviews the evidence

Whether you enjoy chocolate milk regularly, as a weekend treat, or as an occasional dose of childhood nostalgia, it probably wouldn’t be the first option you think of for post-workout recovery.
Unless you’re on TikTok, perhaps. According to many people on the social media platform, chocolate milk is not only delicious, but it offers benefits comparable to sports drinks after a workout.
So is there any evidence to support this? Let’s take a look.
Rehydrating after a workout is important
Water accounts for somewhere between 50% and 60% of our body weight. Water has many important functions in the body, including helping to keep our body at the right temperature through sweating.
We lose water naturally from our bodies when we sweat, as well as through our breathing and when we go to the toilet. So it’s important to stay hydrated to replenish the water we lose.
When we don’t, we become dehydrated, which can put a strain on our bodies. Signs and symptoms of dehydration can range from thirst and dizziness to low blood pressure and confusion.
Athletes, because of their higher levels of exertion, lose more water through sweating and from respiration (when their breathing rate gets faster). If they’re training or competing in hot or humid environments they will sweat even more.
Dehydration impacts athletes’ performance and like for all of us, can affect their health.
So finding ways to ensure athletes rehydrate quickly during and after they train or compete is important. Fortunately, sports scientists and dietitians have done research looking at the composition of different fluids to understand which ones rehydrate athletes most effectively.
The beverage hydration index
The best hydrating drinks are those the body retains the most of once they’ve been consumed. By doing studies where they give people different drinks in standardised conditions, scientists have been able to determine how various options stack up.
To this end, they’ve developed something called the beverage hydration index, which measures to what degree different fluids hydrate a person compared to still water.
According to this index beverages with similar fluid retention to still water include sparkling water, sports drinks, cola, diet cola, tea, coffee, and beer below 4% alcohol. That said, alcohol is probably best avoided when recovering from exercise.
Beverages with superior fluid retention to still water include milk (both full-fat and skim), soy milk, orange juice and oral rehydration solutions.
This body of research indicates that when it comes to rehydration after exercise, unflavoured milk (full fat, skim or soy) is better than sports drinks.
But what about chocolate milk?
A small study looked at the effects of chocolate milk compared to plain milk on rehydration and exercise performance in futsal players (futsal is similar to soccer but played on a court indoors). The researchers found no difference in rehydration between the two. There’s no other published research to my knowledge looking at how chocolate milk compares to regular milk for rehydration during or after exercise.
But rehydration isn’t the only thing athletes look for in sports drinks. In the same study, drinking chocolate milk after play (referred to as the recovery period) increased the time it took for the futsal players to become exhausted in further exercise (a shuttle run test) four hours later.
This was also shown in a review of several clinical trials. The analysis found that, compared to different placebos (such as water) or other drinks containing fat, protein and carbohydrates, chocolate milk lengthened the time to exhaustion during exercise.
What’s in chocolate milk?
Milk contains protein, carbohydrates and electrolytes, each of which can affect hydration, performance, or both.
Protein is important for building muscle, which is beneficial for performance. The electrolytes in milk (including sodium and potassium) help to replace electrolytes lost through sweating, so can also be good for performance, and aid hydration.
Compared to regular milk, chocolate milk contains added sugar. This provides extra carbohydrates, which are likewise beneficial for performance. Carbohydrates provide an immediate source of energy for athletes’ working muscles, where they’re stored as glycogen. This might contribute to the edge chocolate milk appears to have over plain milk in terms of athletic endurance.
Coffee-flavoured milk has an additional advantage. It contains caffeine, which can improve athletic performance by reducing the perceived effort that goes into exercise.
One study showed that a frappe-type drink prepared with filtered coffee, skim milk and sugar led to better muscle glycogen levels after exercise compared to plain milk with an equivalent amount of sugar added.
So what’s the verdict?
Evidence shows chocolate milk can rehydrate better than water or sports drinks after exercise. But there isn’t evidence to suggest it can rehydrate better than plain milk. Chocolate milk does appear to improve athletic endurance compared to plain milk though.
Ultimately, the best drink for athletes to consume to rehydrate is the one they’re most likely to drink.
While many TikTok trends are not based on evidence, it seems chocolate milk could actually be a good option for recovery from exercise. And it will be cheaper than specialised sports nutrition products. You can buy different brands from the supermarket or make your own at home with a drinking chocolate powder.
This doesn’t mean everyone should look to chocolate milk when they’re feeling thirsty. Chocolate milk does have more calories than plain milk and many other drinks because of the added sugar. For most of us, chocolate milk may be best enjoyed as an occasional treat.

Getting to Neutral – by Trevor Moawad
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 that a pessimistic outlook is self-defeating… And yet, toxic positivity can also be a set-up for failure! At some point, reckless faith in the kindly nature of the universe will get crushed, badly. Sometimes that point is a low point in life… sometimes it’s six times a day. But one thing’s for sure: we can’t “just decide everything will go great!” because the world just doesn’t work that way.
That’s where Trevor Moawad comes in. “Getting to neutral” is not a popular selling point. Everyone wants joy, abundance, and high after high. And neutrality itself is often associated with boredom and soullessness. But, Moawad argues, it doesn’t have to be that way.
This book’s goal—which it accomplishes well—is to provide a framework for being a genuine realist. What does that mean?
“I’m not a pessimist; I’m a realist” – every pessimist ever.
^Not that. That’s not what it means. What it means instead is:
- Hope for the best
- Prepare for the worst
- Adapt as you go
…taking care to use past experiences to inform future decisions, but without falling into the trap of thinking that because something happened a certain way before, it always will in the future.
To be rational, in short. Consciously and actively rational.
Feel the highs! Feel the lows! But keep your baseline when actually making decisions.
Bottom line: this book is as much an antidote to pessimism and self-defeat, as it is to reckless optimism and resultant fragility. Highly recommendable.
Click here to check out “Getting to Neutral” and start creating your best, most reason-based life!
PS: in this book, Moawad draws heavily from his own experiences of battling adversity in the form of cancer—of which he died, before this book’s publication. A poignant reminder that he was right: we won’t always get the most positive outcome of any given situation, so what matters the most is making the best use of the time we have.

Zucchini & Oatmeal Koftas
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.
These vegetarian (and with one tweak, vegan) koftas are delicious as a snack, light lunch, or side to a larger meal. Healthwise, they contain the healthiest kind of fiber, as well as omega-3 fatty acids, and beneficial herbs and spices.
You will need
- ¼ cup oatmeal
- 1 large zucchini, grated
- 1 small carrot, grated
- ¼ cup cheese (your preference; vegan is also fine)
- 2 tbsp ground flaxseed
- 2 tbsp nutritional yeast
- ¼ bulb garlic, minced
- 2 tsp black pepper, coarse ground
- ½ tsp MSG or 1 tsp low-sodium salt
- Small handful fresh parsley, chopped
- Extra virgin olive oil, for frying
Method
(we suggest you read everything at least once before doing anything)
1) Soak the flaxseed in 2 oz hot water for at least 5 minutes
2) Combine all of the ingredients except the olive oil (and including the water that the flax has been soaking in) in a big bowl, mixing thoroughly
3) Shape into small balls, patties, or sausage shapes, and fry until the color is golden and the structural integrity is good. If doing patties, you’ll need to gently flip them to cook both sides; otherwise, rolling them to get all sides is fine.
4) Serve! Traditional is with some kind of yogurt dip, but we’re not the boss of you, so enjoy them how you like:
Enjoy!

Can We Side-Step Age-Related Alienation?
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.
When The World Moves Without Us…
We’ve written before about how reduced social engagement can strike people of all ages, and what can be done about it:
How To Beat Loneliness & Isolation
…but today we’re going to talk more about a specific aspect of it, namely, the alienation that can come with old age—and other life transitions too, but getting older is something that (unless accident or incident befall us first) all of us will definitely do.
What’s the difference?
Loneliness is a status, alienation is more of a process. It can be the alienation in the sense of an implicit “you don’t belong here” message from the world that’s geared around the average person and thus alienates those who are not that (a lack of accessibility to people with disabilities can be an important and very active example of this), and it can also be an alienation from what we’ve previously considered our “niche” in the world—the loss of purpose many people feel upon retirement fits this bill. It can even be a more generalized alienation from our younger selves; it’s easy to have a self-image that doesn’t match one’s current reality, for instance.
Read more: Estranged by Time: Alienation in the Aging Process
So, how to “un-alienate”?
To “un-alienate”, that is to say, to integrate/reintegrate, can be hard. Some things may even be outright impossible, but most will not be!
Consider how, for example, former athletes become coaches—or for that matter, how former party-goers might become party-hosts (even if the kind of “party” might change with time, give or take the pace at which we like to live our lives).
What’s important is that we take what matters the most to us, and examine how we can realistically still engage with that thing.
This is different from trying to hold on grimly to something that’s no longer our speed.
Letting go of the only thing we’ve known will always be scary; sometimes it’s for the best, and sometimes what we really need is just more of a pivot, like the examples above. The crux lies in knowing which:
- Is our relationship with the thing (whatever it may be) still working for us, or is it just bringing strife now?
- If it’s not working for us, is it because of a specific aspect that could be side-stepped while keeping the rest?
- If we’re going to drop that thing entirely (or be dropped by it, which, while cruel, also happens in life), then where are we going to land?
This latter is one where foresight is a gift, because if we bury our heads in the sand we’re going to land wherever we’re dropped, whereas if we acknowledge the process, we can make a strategic move and land on our feet.
Here’s a good pop-science article about this—it’s aimed at people around retirement age, but honestly the advice is relevant for people of all ages, and facing all manner of life transitions, e.g. career transitions (of which retirement is of course the career transition to end all career transitions), relationship transitions (including B/B/B/B: births, betrothals/break-ups, and bereavements) health transitions (usually: life-changing illnesses and/or disabilities—which again, happens to most of us if something doesn’t get us first), etc. So with all that in mind, this becomes more of a “how to reassess your life at those times when it needs reassessing”:
How to Reassess Your Life in Retirement
But that doesn’t mean that letting go is always necessary
Sometimes, the opposite! Sometimes, the age-old advice to “lean in” really is all the situation calls for, which means:
- Be ready to say “yes” to things, and if nobody’s asking, be ready to “hey, do you wanna…?” and take a “build it and they will come” approach. This includes with people of different ages, too! Intergenerational friendships can be very rewarding for all concerned, if done right. Communities that span age-ranges can be great for this—they might be about special interests (this writer has friends ranging through four generations from playing chess, for instance), they could be religious communities if we be religious, LGBT groups if that fits for us, even mutual support groups such as for specific disabilities or chronic illness if we have such—notice how the very things that might isolate us can also bring us together!
- Be open-minded to new experiences; it’s easy to get stuck in a rut of “I’ve never done that” and mistake that self-assessment for an uncritical assumption of “I’m not the kind of person who does that”. Sometimes, you really won’t be! But at least think about it and entertain the possibility, before dismissing it out of hand. And, here’s a life tip: it can be really good to (within the realms of safety, and one’s personal moral principles, of course) take an approach of “try anything once”. Even if we’re almost certain we won’t like it, and even if we then turn out to indeed not like it, it can be a refreshing experience—and now we can say “Yep, tried that, not doing that again” from a position of informed knowledge. That’s the only way we get to look back on a richly lived life of broad experiences, after all, and it is never too late for such.
- Be comfortable prioritizing quality over quantity. This goes for friends, it goes for activities, it goes for experiences. The topic of “what’s the best number of friends to have?” has been a matter of discussion since at least ancient Greek times (Plato and Aristotle examined this extensively), but whatever number we might arrive at, it’s clear that quality is the critical factor, and quantity after that is just a matter of optimizing.
In short: make sure you’re investing—in your relationships, in your areas of interest, in your community (whatever that may mean for you personally), and most of all, and never forget this: in yourself.
Take care!

The Good, The Bad, & The Vigorously Debated
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 week in health news sees some pretty varied topics:
One more reason to care about the gut-brain axis
Stroke is a top killer in much of the industrialized world, usually making it into the top-few list on a per-country basis. And, it’s rising in prevalence, too. This is partly because our longevity is increasing so age-related things kill us more often, statistically, than age-unrelated things. But that’s only part of the reason; another is that our lifestyle (on the national level) is becoming more conducive to stroke. Diet is a large contributor to that, and gut health has now been identified as a key factor.
What recent research has shown is that minutes after a stroke occurs, normal gut anatomy is disrupted, and cells responsible for gut barrier integrity are eroded, and bugs from the gut get into the blood, and arrive at the (newly damaged) brain vasculature, where the blood-brain barrier is often also compromised on account of the stroke.
Because of this, critical to reducing post-stroke neuroinflammation (something that makes stroke damage more severe and recovery a lot harder) is improving the gut’s ability to heal itself quickly.
This can be helped with a dose of Insulin-like Growth Factor (IGF-1), but there are other things that can help or hinder, and those other things are modifiable by us as individuals in our lifestyle choices (e.g. a gut-healthy diet with plenty of fiber, and avoiding gut-unhealthy things like sugar and alcohol that feed C. albicans growths that will put roots through your intestines and make holes as they do), because the better/worse your gut barrier integrity is to start with, the easier/harder it will be for your gut to repair itself quickly:

How about that seasonal lead-spiced hot drink?
Lead contamination in ground spices has become a bit of an issue, ground turmeric has had quite some flak in this regard, and now the spotlight is on cinnamon.
These reports, by the way, do not specify what kind of cinnamon (i.e. cassia vs Ceylon), however, clicking through to assorted sources and then doing our own digging finds that all cinnamon products we found listed as contaminated, were cassia cinnamon. This is unsurprising, as a) it’s cheaper b) it’s the kind most readily found on shelves in the US. That said, when it comes to Ceylon (sweet) cinnamon, absence of evidence is not evidence of absence, so that doesn’t mean they got the all-clear on lead contamination, but rather, that they haven’t received the same scrutiny as yet.
It’s worth noting that cinnamon sticks have been found to have less contamination than ground cinnamon, though.
It’s also worth noting that since some adulterated products have had lead added deliberately in increase the weight and darken the color, this is more likely to happen to cassia cinnamon than sweet cinnamon because cassia cinnamon is visibly darker, so adding a darkening agent to sweet cinnamon would just make it look like cassia (which no seller would want to do since cassia is the cheaper of the two).

A matter of life and death
Assisted dying is currently legal in 10/40 US states, and Canada. Over in the UK, it’s being debated (and voted on) in Parliament today, at time of writing.
While bodily autonomy discussions are usually quite straightforward arguments between the very separate camps of
- “my body, my choice” vs
- “they shouldn’t be allowed to do that”,
…this one comes with a considerable middleground, because
- “people should have to right to end things without extra suffering and on their own terms”, and
- “many disabled people fear being placed in a position of having justify why they are not exercising their right to die when it might be cheaper and easier for others if they did”
…are positions with a lot of potential overlap.
In any case, we know most of our readers are in the US, but with a 10/40 split in US states (and some recent controversies in Canada), it’s likely a topic that’ll come up for most people at some point, so it’s good to understand it, and this is as good an opportunity as any:

Play Bold – by Magnus Penker
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 book is very different to what you might expect, from the title.
We often see: “play bold, believe in yourself, the universe rewards action” etc… Instead, this one is more: “play bold, pay attention to the data, use these metrics, learn from what these businesses did and what their results were”, etc.
We often see: “here’s an anecdote about a historical figure and/or celebrity who made a tremendous bluff and it worked out well so you should too” etc… Instead, this one is more: “see how what we think of as safety is actually anything but! And how by embracing change quickly (or ideally: proactively), we can stay ahead of disaster that may otherwise hit us”.
Penker’s background is also relevant here. He has decades of experience, having “launched 10 start-ups and acquired, turned around, and sold over 30 SMEs all over Europe”. Importantly, he’s also “still in the game”… So, unlike many authors whose last experience in the industry was in the 1970s and who wonder why people aren’t reaping the same rewards today!
Penker is the therefore opposite of many who advocate to “play bold” but simply mean “fail fast, fail often”… While quietly relying on their family’s capital and privilege to leave a trail of financial destruction behind them, and simultaneously gloating about their imagined business expertise.
In short: boldness does not equate to foolhardiness, and foolhardiness does not equate to boldness.
As for telling the difference? Well, for that we recommend reading the book—It’s a highly instructive one.

The Rise Of The Machines
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 this week’s health science news, several pieces of technology caught our eye. Let’s hope these things roll out widely!
When it comes to UTIs, antimicrobial resistance is taking the p—
This has implications far beyond UTIs—though UTIs can be a bit of a “canary in the coal mine” for antimicrobial resistance. The more people are using antibiotics (intentionally, or because they are in the food chain), the more killer bugs are proliferating instead of dying when we give them something to kill them. And yes: they do proliferate sometimes when given antibiotics, not because the antibiotics did anything directly good for them, but because they killed their (often friendly bacteria) competition. Thus making for a double-whammy of woe.
This development tackles that, by using AI modelling to crunch the numbers of a real-time data-driven personalized approach to give much more accurate treatment options, in a way that a human couldn’t (or at least, couldn’t at anything like the same speed, and most family physicians don’t have a mathematician locked in the back room to spend the night working on a patient’s data).

When it comes to CPR and women, people are feint of heart
When CPR is needed, time is very much of the essence. And yet, bystanders are much less likely to give CPR to a woman than to a man. Not only that, but CPR-training is part of what leads to this reluctance when it comes to women: the mannequins used are very homogenous, being male (94%) and lean (99%). They’re also usually white (88%) even in countries where the populations are not, but that is less critical. After all, a racist person is less likely to give CPR to a person of color regardless of what color the training mannequin was.
However, the mannequins being male and lean is an issue, because it means people suddenly lack confidence when faced with breasts and/or abundant body fat. Both can prompt the bystander to wonder if some different technique is needed (it isn’t), and breasts can also prompt the bystander to fear doing something potentially “improper” (the proper course of action is: save a person’s life; do not get distracted by breasts).
Read in full: Women are less likely to receive CPR than men. Training on manikins with breasts could help ← there are also CPR instructions (and a video demonstration) there, for anyone who wants a refresher, if perhaps your last first-aid course was a while ago!

When technology is a breath of fresh air
A woman with COPD and COVID has had her very damaged lungs replaced using a da Vinci X robot to perform a minimally-invasive surgery (which is quite a statement, when it comes to replacing someone’s lungs).
Not without human oversight though—surgeon Dr. Stephanie Chang was directing the transplant. Surgery is rarely fun for the person being operated on, but advances like this make things go a lot more smoothly, so this kind of progress is good to see.
