Sea moss is the latest “superfood” wellness influencers are swearing by. They claim sea moss products – usually in gel form – have multiple health benefits. These include supporting brain and immune function, or protecting against viruses and other microbes.
But do these health claims stack up? Let’s take a look.
What is sea moss?
Sea moss is produced using a kind of seaweed – particularly red algae – that grow in various locations all around the world. Three main species are used in sea moss products:
- Chondrus crispus (known as Irish moss or carrageenan moss)
- Eucheuma cottonii (sea moss or seabird’s nest)
- Gracilaria (Irish moss or ogonori).
Some products also contain the brown algae Fucus vesiculosus (commonly known as bladderwrack, black tang, rockweed, sea grapes, bladder fucus, sea oak, cut weed, dyers fucus, red fucus or rock wrack).
Most sea moss products are sold as a gel that can be added to recipes, used in smoothies, frozen into ice cubes or eaten on its own. The products also come in capsule form or can be purchased “raw” and used to make your own gels at home.
What’s the evidence?
Sea moss products claim a host of potential health benefits, from supporting immunity, to promoting skin health and enhancing mood and focus, among many others.
But is there any evidence supporting these claims?
Recent studies have reviewed the biological properties of the main sea moss species (Chondrus crispus, Eucheuma cottonii, Gracilaria and Fucus vesiculosus).
They suggest these species may have anti-inflammatory, antioxidant, anticancer, antidiabetic and probiotic properties.
However, the vast majority of research relating to Chondrus crispus, Gracilaria and Fucus vesiculosus – and all of the research on Eucheuma cottonii – comes from studies done in test tubes or using cell and animal models. We should not assume the health effects seen would be the same in humans.
In cell and animal studies, researchers usually administer algae in a laboratory and use specific extracts rich in bioactive compounds rather than commercially available sea moss products.
They also use very different – often relatively larger – amounts compared to what someone would typically consume when they eat sea moss products.
This means the existing studies can’t tell us about the human body’s processes when eating and digesting sea moss.
Sea moss may have similar effects in humans. But so far there is very little evidence people who consume sea moss will experience any of the claimed health benefits.
Nutritional value
Eating sea moss does not replace the need for a balanced diet, including a variety of fruits and vegetables.
Chondrus crispus, Eucheuma cottonii and Gracilaria, like many seaweeds, are rich sources of nutrients such as fatty acids, amino acids, vitamin C and minerals. These nutrients are also likely to be present in sea moss, although some may be lost during the preparation of the product (for example, soaking may reduce vitamin C content), and those that remain could be present in relatively low quantities.
There are claims that sea moss may be harmful for people with thyroid problems. This relates to the relationship between thyroid function and iodine. The algae used to make sea moss are notable sources of iodine and excess iodine intake can contribute to thyroid problems, particularly for people with pre-existing conditions. That is why these products often carry disclaimers related to iodine sensitivity or thyroid health.
Is it worth it?
So you may be wondering if it’s worth trying sea moss. Here are a few things to consider before you decide whether to start scooping sea moss into your smoothies.
A 375mL jar costs around $A25–$30 and lasts about seven to ten days, if you follow the recommended serving suggestion of two tablespoons per day. This makes it a relatively expensive source of nutrients.
Sea moss is often hyped for containing 92 different minerals. While there may be 92 minerals present, the amount of minerals in the algae will vary depending on growing location and conditions.
The efficiency with which minerals from algae can be absorbed and used by the body also varies for different minerals. For example, sodium is absorbed well, while only about 50% of iodine is absorbed.
But sea moss has also been shown to contain lead, mercury and other heavy metals – as well as radioactive elements (such as radon) that can be harmful to humans. Seaweeds are known for their ability to accumulate minerals from their environment, regardless of whether these are beneficial or harmful for human nutrition. Remember, more doesn’t always mean better.
What else am I eating?
While you won’t get a full nutritional breakdown on the jar, it is always wise to check what other ingredients you may be eating. Sea moss products can contain a range of other ingredients, such as lime, monk fruit powder, spirulina and ginger, among many others.
These ingredients differ between brands and products, so be aware of your needs and always check.
Despite their health claims, most sea moss products also carry disclaimers indicating that the products are not intended to diagnose, treat, cure or prevent any disease.
If you have concerns about your health, always speak to a health professional for accurate and personalised medical advice.

Rethinking Diabetes – by Gary Taubes
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’ve previously reviewed this author’s “The Case Against Sugar” and “Why We Get Fat And What To Do About It“. There’s an obvious theme, and this book caps it off nicely:
By looking at the history of diabetes treatment (types 1 and 2) in the past hundred years, and analysing the patterns over time, we can see how:
- diabetics have been misled a lot over time by healthcare providers
- we can learn from those mistakes going forwards
Happily, he does this without crystal-balling the future or expecting diet to fix, for example, a pancreas that can’t produce insulin. But what he does do is focus on the “can” items rather than the “can’t” items.
In the category of criticism, one of the strategies he argues for is basically the keto diet, which is indeed just fine for diabetes but often not great for the heart in the long-term (it depends on various factors, including genes). However, even if you choose not to implement that, there is plenty more to try out in this book.
Bottom line: whether you have diabetes, love someone who does, or just plain like to be on top of your glycemic health, this book is full of important insights and opportunities to improve things progressively along the way.

Eat All You Want (But Wisely)

Some Surprising Truths About Hunger And Satiety
This is Dr. Barbara Rolls. She’s Professor and Guthrie Chair in Nutritional Sciences, and Director of the Laboratory for the Study of Human Ingestive Behavior at Pennsylvania State University, after graduating herself from Oxford and Cambridge (yes, both). Her “awards and honors” take up four A4 pages, so we won’t list them all here.
Most importantly, she’s an expert on hunger, satiety, and eating behavior in general.
What does she want us to know?
First and foremost: you cannot starve yourself thin, unless you literally starve yourself to death.
What this is about: any weight lost due to malnutrition (“not eating enough” is malnutrition) will always go back on once food becomes available. So unless you die first (not a great health plan), merely restricting good will always result in “yo-yo dieting”.
So, to avoid putting the weight back on and feeling miserable every day along the way… You need to eat as much as you feel you need.
But, there’s a trick here (it’s about making you genuinely feel you need less)!
Your body is an instrument—so play it
Your body is the tool you use to accomplish pretty much anything you do. It is, in large part, at your command. Then there are other parts you can’t control directly.
Dr. Rolls advises taking advantage of the fact that much of your body is a mindless machine that will simply follow instructions given.
That includes instructions like “feel hungry” or “feel full”. But how to choose those?
Volume matters
An important part of our satiety signalling is based on a physical sensation of fullness. This, by the way, is why bariatric surgery (making a stomach a small fraction of the size it was before) works. It’s not that people can’t eat more (the stomach is stretchy and can also be filled repeatedly), it’s that they don’t want to eat more because the pressure sensors around the stomach feel full, and signal the hormone leptin to tell the brain we’re full now.
Now consider:
- On the one hand, 20 grapes, fresh and bursting with flavor
- On the other hand, 20 raisins (so, dried grapes), containing the same calories
Which do you think will get the leptin flowing sooner? Of course, the fresh grapes, because of the volume.
So if you’ve ever seen those photos that show two foods side by side with the same number of calories but one is much larger (say, a small slice of pizza or a big salad), it’s not quite the cheap trick that it might have appeared.
Or rather… It is a cheap trick; it’s just a cheap trick that works because your stomach is quite a simple organ.
So, Dr. Rolls’ advice: generally speaking, go for voluminous food. Fruit is great from this, because there’s so much water. Air-popped popcorn also works great. Vegetables, too.
Water matters, but differently than you might think
A well-known trick is to drink water before and with a meal. That’s good, it’s good to be hydrated. However, it can be better. Dr. Rolls did an experiment:
The design:
❝Subjects received 1 of 3 isoenergetic (1128 kJ) preloads 17 min before lunch on 3 d and no preload on 1 d.
The preloads consisted of 1) chicken rice casserole, 2) chicken rice casserole served with a glass of water (356 g), and 3) chicken rice soup.
The soup contained the same ingredients (type and amount) as the casserole that was served with water.❞
The results:
❝Decreasing the energy density of and increasing the volume of the preload by adding water to it significantly increased fullness and reduced hunger and subsequent energy intake at lunch.
The equivalent amount of water served as a beverage with a food did not affect satiety.❞
The conclusion:
❝Consuming foods with a high water content more effectively reduced subsequent energy intake than did drinking water with food.❞
You can read the study in full (it’s a worthwhile read!) here:
Water incorporated into a food but not served with a food decreases energy intake in lean women
Protein matters
With all those fruits and vegetables and water, you may be wondering Dr. Rolls’ stance on proteins. It’s simple: protein is an appetite suppressant.
However, it takes about 20 minutes to signal the brain about that, so having some protein in a starter (if like this writer, you’re the cook of the household, a great option is to enjoy a small portion of nuts while cooking!) gets that clock ticking, to signal satiety sooner.
It may also help in other ways:
Clinical Evidence and Mechanisms of High-Protein Diet-Induced Weight Loss
As for other foods that can suppress appetite, by the way, you might like;
25 Foods That Act As Natural Appetite Suppressants
Variety matters, and in ways other than you might think
A wide variety of foods (especially: a wide variety of plants) in one’s diet is well recognized as a key to a good balanced diet.
However…
A wide variety of dishes at the table, meanwhile, promotes greater consumption of food.
Dr. Rolls did a study on this too, a while ago now (you’ll see how old it is) but the science seems robust:
Variety in a Meal Enhances Food Intake in Man
Notwithstanding the title, it wasnot about a man (that was just how scientists wrote in ye ancient times of 1981). The test subjects were, in order: rats, cats, a mixed group of men and women, the same group again, and then a different group of all women.
So, Dr. Rolls’ advice is: it’s better to have one 20-ingredient dish, than 10 dishes with 20 ingredients between them.
Sorry! We love tapas and buffets too, but that’s the science!
So, “one-pot” meals are king in this regard; even if you serve it with one side (reasonable), that’s still only two dishes, which is pretty good going.
Note that the most delicious many-ingredient stir-fries and similar dishes from around the world also fall into this category!

Why are my muscles sore after exercise? Hint: it’s nothing to do with lactic acid
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.
As many of us hit the gym or go for a run to recover from the silly season, you might notice a bit of extra muscle soreness.
This is especially true if it has been a while between workouts.
A common misunderstanding is that such soreness is due to lactic acid build-up in the muscles.
Research, however, shows lactic acid has nothing to do with it. The truth is far more interesting, but also a bit more complex.
It’s not lactic acid
We’ve known for decades that lactic acid has nothing to do with muscle soreness after exercise.
In fact, as one of us (Robert Andrew Robergs) has long argued, cells produce lactate, not lactic acid. This process actually opposes not causes the build-up of acid in the muscles and bloodstream.
Unfortunately, historical inertia means people still use the term “lactic acid” in relation to exercise.
Lactate doesn’t cause major problems for the muscles you use when you exercise. You’d probably be worse off without it due to other benefits to your working muscles.
Lactate isn’t the reason you’re sore a few days after upping your weights or exercising after a long break.
So, if it’s not lactic acid and it’s not lactate, what is causing all that muscle soreness?
Muscle pain during and after exercise
When you exercise, a lot of chemical reactions occur in your muscle cells. All these chemical reactions accumulate products and by-products which cause water to enter into the cells.
That causes the pressure inside and between muscle cells to increase.
This pressure, combined with the movement of molecules from the muscle cells can stimulate nerve endings and cause discomfort during exercise.
The pain and discomfort you sometimes feel hours to days after an unfamiliar type or amount of exercise has a different list of causes.
If you exercise beyond your usual level or routine, you can cause microscopic damage to your muscles and their connections to tendons.
Such damage causes the release of ions and other molecules from the muscles, causing localised swelling and stimulation of nerve endings.
This is sometimes known as “delayed onset muscle soreness” or DOMS.
While the damage occurs during the exercise, the resulting response to the injury builds over the next one to two days (longer if the damage is severe). This can sometimes cause pain and difficulty with normal movement.
The upshot
Research is clear; the discomfort from delayed onset muscle soreness has nothing to do with lactate or lactic acid.
The good news, though, is that your muscles adapt rapidly to the activity that would initially cause delayed onset muscle soreness.
So, assuming you don’t wait too long (more than roughly two weeks) before being active again, the next time you do the same activity there will be much less damage and discomfort.
If you have an exercise goal (such as doing a particular hike or completing a half-marathon), ensure it is realistic and that you can work up to it by training over several months.
Such training will gradually build the muscle adaptations necessary to prevent delayed onset muscle soreness. And being less wrecked by exercise makes it more enjoyable and more easy to stick to a routine or habit.
Finally, remove “lactic acid” from your exercise vocabulary. Its supposed role in muscle soreness is a myth that’s hung around far too long already.

Overcome Front-Of-Hip Pain
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. Alyssa Kuhn, physiotherapist, demonstrates how:
One, two, three…
One kind of pain affects a lot of related things: hip pain has an impact on everything that’s connected to the pelvis, which is basically the rest of the body, but especially the spine itself. For this reason, it’s critical to keep it in as good condition as possible.
Two primary causes of hip stiffness and pain:
- Anterior pelvic tilt due to posture, weight distribution, or pain. This tightens the front muscles and weakens the back muscles.
- Prolonged sitting, which tightens the hip muscles due to inactivity.
Three exercises are recommended by Dr. Kuhn to relieve pain and stiffness:
- Bridge exercise:
- Lie on a firm surface with your knees bent.
- Push through your feet, engage your hamstrings, and flatten your lower back.
- Hold for 3–5 seconds, relax, and repeat (10–20 reps).
- Wall exercise with arms:
- Stand with your lower back against the wall, feet a step away.
- Tilt your hips backwards, keeping your lower back in contact with the wall.
- Alternate lifting one arm at a time while maintaining back contact with the wall (10–20 reps).
- Wall exercise with legs:
- Same stance as the previous exercise but wider now.
- Lift one heel at a time while keeping your hips stable and your back against the wall.
- Practice for 30–60 seconds, maintaining good form.
As ever, consistency is key for long-term relief. Dr. Kuhn recommends doing these regularly, especially before any expected periods of prolonged sitting (e.g. at desk, or driving, etc). And of course, do try to reduce, or at least break up, those sitting marathons if you can.

Invigorating Sabzi Khordan
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.
Have you ever looked at the nutritional values and phytochemical properties of herbs, and thought “well that’s all well and good, but we only use a tiny amount”? Sabzi khordan is a herb-centric traditional Levantine sharing platter served most commonly as an appetizer, and it is indeed appetizing! Never again will “start your meal with a green salad to ensure a gentle blood sugar curve” seem like a chore:
You will need
- Large bunch of parsley
- Small bunch of tarragon leaves
- Small bunch of basil leaves
- Small bunch of mint
- Small bunch of sorrel leaves
- 7 oz block of feta cheese (if vegan, a plant-based substitution is fine in culinary terms, but won’t have the same gut-healthy benefits, as plant-based cheeses are not fermented)
- 9 oz labneh-stuffed vine leaves in olive oil (if vegan, same deal as the above, except it’s harder to find plant-based substitutes for labneh (strained yogurt cheese), so you might want to use our Plant-Based Healthy Cream Cheese recipe instead and make your own)
- 2 tbsp za’atar (you can make your own by blending dried hyssop, dried sumac berries, sesame seeds, dried thyme, and salt—but if you haven’t had za’atar before, we recommend first buying some like the one that we linked, so that next time you know what you’re aiming for)
- 3 tbsp extra virgin olive oil
- 10 radishes
- 6 scallions
- 9 oz walnuts, soaked in water overnight and drained
- 1 cucumber, cut into batons
- Warm flatbreads (you can use our Healthy Homemade Flatbreads recipe)
Method
(we suggest you read everything at least once before doing anything)
1) Arrange the feta, labneh, za’atar, and olive oil in separate little serving dishes.
2) Arrange everything else around them on a platter.
3) Serve! You may be thinking: did we really need a recipe to tell us “put the things on a plate”? The answer here is that this one today was shared mostly as a matter of inspiration, because when was the last time you thought to serve herbs as the star of the dish? Plus, it’s an excuse to try za’atar, not something so commonly seen outside of the Levant.

Bath vs Shower – Which is Healthier?
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.
Our Verdict
When comparing bathing to showering, we picked the shower.
Why?
For the basic task of getting your body clean, the shower is better as it is an entirely one-way process. Clean water hits your body, dirty water leaves it, and no dirt is making its way back.
Baths do not have this advantage, and if you enter a bath dirty, you will then be sitting in dirty water. You will leave it a lot cleaner than you entered it (because a lot of the dirt stayed in the bathwater to be drained away after the bath), but not as clean as if you had showered.
One could argue soap or equivalent will prevent the dirt re-sticking, and that’s true, but it’s true for soap in the shower too, so it doesn’t offset anything.
Additionally, being immersed in water for more than 15 minutes can start to have a (paradoxically) dehydrating effect on the skin; this happens not only because of losing skin oils to the water, but also because of osmosis, the resultant mild edema, the body’s homeostatic response to the mild edema, then getting out the bath and drying, leaving one with the response having now just caused dehydrated skin.
Baths do have some health advantages! And these come primarily from the mental health benefits of relaxation in warm water and/or generally pampering oneself. Additionally, some bath oils or bath salts can be beneficial in a way that couldn’t be administered the same way in the shower.
Best of both worlds?
In some parts of the world (Thailand and Turkey come to mind; doubtlessly there are many others) there are traditions of first taking a shower to get clean, and then taking a bath for the rest of the bathing experience. As a bonus, the bathing experience is then all the more pleasant for the water remaining just as clean as it was to start with.
However, if you do have to pick one (and for the purpose of our “This or That” exercise, we do), then it’s the shower, hands-down.
