Is white rice bad for me? Can I make it lower GI or healthier?

Rice is a culinary staple in Australia and around the world.
It might seem like a given that brown rice is healthier than white and official public health resources often recommend brown rice instead of white as a “healthy swap”.
But Australians definitely prefer white rice over brown. So, what’s the difference, and what do we need to know when choosing rice?
What makes rice white or brown?
Rice “grains” are technically seeds. A complete, whole rice seed is called a “paddy”, which has multiple parts:
- the “hull” is the hard outer layer which protects the seed
- the “bran”, which is a softer protective layer containing the seed coat
- the “germ” or the embryo, which is the part of the seed that would develop into a new plant if was germinated
- the “endosperm”, which makes up most of the seed and is essentially the store of nutrients that feeds the developing plant as a seed grows into a plant.
Rice needs to be processed for humans to eat it.
Along with cleaning and drying, the hard hulls are removed since we can’t digest them. This is how brown rice is made, with the other three parts of the rice remaining intact. This means brown rice is regarded as a “wholegrain”.
White rice, however, is a “refined” grain, as it is further polished to remove the bran and germ, leaving just the endosperm. This is a mechanical and not a chemical process.
What’s the difference, nutritionally?
Keeping the bran and the germ means brown rice has more magnesium, phosphorus, potassium B vitamins (niacin, folate, riboflavin and pyridoxine), iron, zinc and fibre.
The germ and the bran also contain more bioactives (compounds in foods that aren’t essential nutrients but have health benefits), like oryzanols and phenolic compounds which have antioxidant effects.
But that doesn’t mean white rice is just empty calories. It still contains vitamins, minerals and some fibre, and is low in fat and salt, and is naturally gluten-free.
White and brown rice actually have similar amounts of calories (or kilojoules) and total carbohydrates.
There are studies that show eating more white rice is linked to a higher risk of type 2 diabetes. But it is difficult to know if this is down to the rice itself, or other related factors such as socioeconomic variables or other dietary patterns.
What about the glycaemic index?
The higher fibre means brown rice has a lower glycaemic index (GI), meaning it raises blood sugar levels more slowly. But this is highly variable between different rices within the white and brown categories.
The GI system uses low (less than 55), medium (55–70) and high (above 70) categories. Brown rices fall into the low and medium categories. White rices fall in the medium and high.
There are specific low-GI types available for both white and brown types. You can also lower the GI of rice by heating and then cooling it. This process converts some of the “available carbohydrates” into “resistant starch”, which then functions like dietary fibre.
Are there any benefits to white rice?
The taste and textural qualities of white and brown rices differ. White rice tends to have a softer texture and more mild or neutral flavour. Brown rice has a chewier texture and nuttier flavour.
So, while you can technically substitute brown rice into most recipes, the experience will be different. Or other ingredients may need to be added or changed to create the desired texture.
Removing more of the outer layers may also reduce the levels of contaminants such as pesticides.
We don’t just eat rice
Comparing white and brown rice seems like an easy way to boost nutritional value. But just because one food (brown rice) is more nutrient-dense doesn’t make the other food (white rice) “bad”.
Ultimately, it’s not often that we eat just rice, so we don’t need the rice we choose to be the perfect one. Rice is typically the staple base of a more complex dish. So, it’s probably more important to think about what we eat with rice.
Adding vegetables and lean proteins to rice-based dishes can easily add the micronutrients, bioactives and fibre that white rice is comparatively lacking, and this can likely do more to contribute to diet quality than eating brown rice instead.

Anise vs Diabetes & Menopause
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 A Daily Gram Of Anise Can Do
Anise, specifically the seed of the plant, also called aniseed, is enjoyed for its licorice taste—as well as its medicinal properties.
Let’s see how well the science lives up to the folk medicine…
What medicinal properties does it claim?
The main contenders are:
- Reduces menopause symptoms
- Reduces blood sugar levels
- Reduces inflammation
Does it reduce menopause symptoms?
At least some of them! Including hot flashes and bone density loss. This seems to be due to the estrogenic-like activity of anethole, the active compound in anise that gives it these effects:
Estrogenic activity of isolated compounds and essential oils of Pimpinella species
1g of anise/day yielded a huge reduction in frequency and severity of hot flashes, compared to placebo*:
*you may be wondering what the placebo is for 1g of a substance that has a very distinctive taste. The researchers used capsules, with 3x330g as the dose, either anise seed or potato starch.
❝In the experimental group, the frequency and severity of hot flashes before the treatment were 4.21% and 56.21% and, after that, were 1.06% and 14.44% at the end of the fourth week respectively. No change was found in the frequency and severity of hot flashes in the control group. The frequency and severity of hot flashes was decreased during 4 weeks of follow up period. P. anisum is effective on the frequency and severity of hot flashes in postmenopausal women. ❞
See for yourself: The Study on the Effects of Pimpinella anisum on Relief and Recurrence of Menopausal Hot Flashes
As for bone mineral density, we couldn’t find a good study for anise, but we did find this one for fennel, which is a plant of the same family and also with the primary active compound anethole:
The Prophylactic Effect of Fennel Essential Oil on Experimental Osteoporosis
That was a rat study, though, so we’d like to see studies done with humans.
Summary on this one: it clearly helps against hot flashes (per the very convincing human study we listed above); it probably helps against bone mineral density loss.
Does it reduce blood sugar levels?
This one got a flurry of attention all so recently, on account of this research review:
Review on Anti-diabetic Research on Two Important Spices: Trachyspermum ammi and Pimpinella anisum
If you read this (and we do recommend reading it! It has a lot more information than we can squeeze in here!) one of the most interesting things about the in vivo anti-diabetic activity of anise was that while it did lower the fasting blood glucose levels, that wasn’t the only effect:
❝Over a course of 60 days, study participants were administered seed powders (5 g/d), which resulted in significant antioxidant, anti-diabetic, and hypolipidemic effects.
Notably, significant reductions in fasting blood glucose levels were observed. This intervention also elicited alterations in the lipid profile, LPO, lipoprotein levels, and the high-density lipoprotein (HDL) level.
Moreover, the serum levels of essential antioxidants, such as beta carotene, vitamin C, vitamin A, and vitamin E, which are typically decreased in diabetic patients, underwent a reversal.❞
That’s just one of the studies cited in that review (the comments lightly edited here for brevity), but it stands out, and you can read that study in its entirety (it’s well worth reading).
Rajeshwari et al, bless them, added a “tl;dr” at the top of their already concise abstract; their “tl;dr” reads:
❝Both the seeds significantly influenced almost all the parameters without any detrimental effects by virtue of a number of phytochemicals, vitamins and minerals present in the seeds having therapeutic effects.❞
Shortest answer: yes, yes it does
Does it fight inflammation?
This one’s quick and simple enough: yes it does; it’s full of antioxidants which thus also have an anti-inflammatory effect:
Review of Pharmacological Properties and Chemical Constituents of Pimpinella anisum
…which can also be used an essential oil, applied topically, to fight both pain and the inflammation that causes it—at least in rats and mice:
❝Indomethacin and etodolac were treated reference drugs for the anti-inflammatory activity. Aspirin and morphine hydrochloride were treated reference drugs for the analgesic activity. The results showed that fixed oil of P. anisum has an anti-inflammatory action more than etodolac and this effect was as strong as indomethacin. P. anisum induces analgesic effect comparable to that of 100 mg/kg Aspirin and 10 mg/kg morphine at 30 th min. of the study❞
Summary of this section:
- Aniseeds are a potent source of antioxidants, which fight inflammation.
- Anise essential oil is probably also useful as a topical anti-inflammatory and analgesic agent, but we’d like to see human tests to know for sure.
Is it safe?
For most people, enjoyed in moderation (e.g., within the dosage parameters described in the above studies), anise is safe. However:
- If you’re allergic to it, it won’t be safe
- Its estrogen-mimicking effects could cause problems if you have (or have a higher risk factor for) breast cancer, ovarian cancer, or endometriosis.
- For most men, the main concern is that it may lower sperm count.
Where to get it?
As ever, we don’t sell it (or anything else), but for your convenience, you can buy the seeds in bulk on Amazon, or in case you prefer it, here’s an example of it available as an essential oil.
Enjoy!

If You’re Not Flexible, These Are The Only 3 Stretches You Need, To Fix That
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 can’t put your leg behind your head while standing, try doing the splits against a wall first, and progress from there! ← text version of an item from a “if you can’t do this yet, try this first” picture set this writer saw on Instagram once upon a time
So, what if you’re more at the point of not quite being able to touch your toes yet?
From zero to…
Liv, of LivInLeggings fame, has these three starter-stretches that are actually starter-stretches:
Stretch 1: Reverse Tabletop with Foot Tuck Variation
- Sit on the floor, feet slightly wider than your hips, lean back onto your hands (fingertips pointing outward).
- Lift your hips towards a reverse tabletop, engage your glutes, and flatten the front of your hips.
- Add a foot tuck variation by stepping one foot back and pressing your weight forward.
Benefits:
- Stretches multiple muscles, including the soles of the feet.
- Improves foot arches, balance, and stability.
- Loosens fascia, enhancing flexibility in subsequent stretches.
Stretch 2: Squat to Forward Fold
- Start in a low squat (feet wider than your hips, toes mostly forward).
- Alternate between a low squat and a forward fold, keeping your hands on the floor or your toes.
Benefits:
- Stretches hamstrings, glutes, and lower back.
- Maintains good form and avoids overstraining.
Stretch 3: Side Lunge with Side Body Reach
- Begin in a tall kneeling position, step one foot out to the side (toes pointing outward).
- Lunge your hips towards your front ankle, keeping your tailbone tucked.
- Add a side body reach by resting your forearm on your thigh and reaching the other arm overhead.
- For a deeper stretch, cradle the back of your head with your hand, pressing lightly for a tricep stretch.
Benefits:
- Stretches inner thighs, lats, and triceps.
- Improves posture, shoulder mobility, and low squat ability.

We created a VR tool to test brain function. It could one day help diagnose dementia
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 or a loved one have noticed changes in your memory or thinking as you’ve grown older, this could reflect typical changes that occur with ageing. In some cases though, it might suggest something more, such as the onset of dementia.
The best thing to do if you have concerns is to make an appointment with your GP, who will probably run some tests. Assessment is important because if there is something more going on, early diagnosis can enable prompt access to the right interventions, supports and care.
But current methods of dementia screening have limitations, and testing can be daunting for patients.
Our research suggests virtual reality (VR) could be a useful cognitive screening tool, and mitigate some of the challenges associated with current testing methods, opening up the possibility it may one day play a role in dementia diagnosis.
Where current testing is falling short
If someone is worried about their memory and thinking, their GP might ask them to complete a series of quick tasks that check things like the ability to follow simple instructions, basic arithmetic, memory and orientation.
These sorts of screening tools are really good at confirming cognitive problems that may already be very apparent. But commonly used screening tests are not always so good at detecting early and more subtle difficulties with memory and thinking, meaning such changes could be missed until they get worse.
A clinical neuropsychological assessment is better equipped to detect early changes. This involves a comprehensive review of a patient’s personal and medical history, and detailed assessment of cognitive functions, including attention, language, memory, executive functioning, mood factors and more. However, this can be costly and the testing can take several hours.
Testing is also somewhat removed from everyday experience, not directly tapping into activities of daily living.
Enter virtual reality
VR technology uses computer-generated environments to create immersive experiences that feel like real life. While VR is often used for entertainment, it has increasingly found applications in health care, including in rehabilitation and falls prevention.
Using VR for cognitive screening is still a new area. VR-based cognitive tests generally create a scenario such as shopping at a supermarket or driving around a city to ascertain how a person would perform in these situations.
Notably, they engage various senses and cognitive processes such as sight, sound and spatial awareness in immersive ways. All this may reveal subtle impairments which can be missed by standard methods.
VR assessments are also often more engaging and enjoyable, potentially reducing anxiety for those who may feel uneasy in traditional testing environments, and improving compliance compared to standard assessments.
Millions of people around the world have dementia.
pikselstock/ShutterstockMost studies of VR-based cognitive tests have explored their capacity to pick up impairments in spatial memory (the ability to remember where something is located and how to get there), and the results have been promising.
Given VR’s potential for assisting with diagnosis of cognitive impairment and dementia remains largely untapped, our team developed an online computerised game (referred to as semi-immersive VR) to see how well a person can remember, recall and complete everyday tasks. In our VR game, which lasts about 20 minutes, the user role plays a waiter in a cafe and receives a score on their performance.
To assess its potential, we enlisted more than 140 people to play the game and provide feedback. The results of this research are published across three recent papers.
Testing our VR tool
In our most recently published study, we wanted to verify the accuracy and sensitivity of our VR game to assess cognitive abilities.
We compared our test to an existing screening tool (called the TICS-M) in more than 130 adults. We found our VR task was able to capture meaningful aspects of cognitive function, including recalling food items and spatial memory.
We also found younger adults performed better in the game than older adults, which echoes the pattern commonly seen in regular memory tests.
Adults of a range of ages tried our computerised game.
pikselstock/ShutterstockIn a separate study, we followed ten adults aged over 65 while they completed the game, and interviewed them afterwards. We wanted to understand how this group – who the tool would target – perceived the task.
These seniors told us they found the game user-friendly and believed it was a promising tool for screening memory. They described the game as engaging and immersive, expressing enthusiasm to continue playing. They didn’t find the task created anxiety.
For a third study, we spoke to seven health-care professionals about the tool. Overall they gave positive feedback, and noted its dynamic approach to age-old diagnostic challenges.
However, they did flag some concerns and potential barriers to implementing this sort of tool. These included resource constraints in clinical practice (such as time and space to carry out the assessment) and whether it would be accessible for people with limited technological skills. There was also some scepticism about whether the tool would be an accurate method to assist with dementia diagnosis.
While our initial research suggests this tool could be a promising way to assess cognitive performance, this is not the same as diagnosing dementia. To improve the test’s ability to accurately detect those who likely have dementia, we’ll need to make it more specific for that purpose, and carry out further research to validate its effectiveness.
We’ll be conducting more testing of the game soon. Anyone interested in giving it a go to help with our research can register on our team’s website.

Hanging Exercises For Complete Beginners & Older Adults
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.
Hanging (not the kind with a gallows) is great for the heath, improving not just strength and mobility, but also—critically—looking after spinal health too. Amanda Raynor explains in this video how this exercise is accessible to anyone (unless you have no arms, in which case, sorry, this one is just not for you—though hanging by your legs will also give similar spinal benefits!).
Hanging out
Hanging can be done at home or at a park, with minimal equipment (a bar, a sturdy tree branch, etc).
Note: the greater the diameter of the bar, the more it will work your grip strength, and/but the harder it will be. So, it’s recommend to start with a narrow-diameter bar first.
Getting started:
- Start with a “dead hang”: grip the bar with hands shoulder-width apart, thumb wrapped around.
- Aim to hang without pulling up; build endurance gradually (10–30 seconds is fine at first).
- Work up to holding for 60 seconds in three sets as a fitness goal.
Progression:
- If unable to hang at all initially, use a chair or stool to support some body weight.
- Gradually reduce foot support to increase duration of free hanging.
- Start with 10 seconds, progressing by small increments (e.g: 15, 20, 25 seconds) until reaching 60 seconds.
Advanced variations:
- Move the body while hanging (e.g., circles, knee lifts).
- Experiment with different grips (overhand, underhand) for varied muscle engagement.
- Try scapular pulls or one-arm hangs for additional challenge and strength-building.

The Best Foods For Collagen Production
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. Andrea Suarez gives us the low-down on collagen synthesis and maintenance. Collagen is the most abundant protein in our body, and it can be fairly described as “the stuff that holds us together”. It’s particularly important for joints and bones too, though many people’s focus on it is for the skin. Whatever your priorities, collagen levels are something it pays to be mindful of, as they usually drop quite sharply after a certain age. What certain age? Well, that depends a lot on you, and your diet and lifestyle. But it can start to decline from the age of 30 with often noticeable drop-offs in one’s mid-40s and again in one’s mid-60s.
Showing us what we’re made of
There’s a lot more to having good collagen levels than just how much collagen we consume (which for vegetarians/vegans, will be “none”, unless using the “except if for medical reasons” exemption, which is probably a little tenuous in the case of collagen but nevertheless it’s a possibility; this exemption is usually one that people use for, say, a nasal spray vaccine that contains gelatine, or a medicinal tablet that contains lactose, etc).
Rather, having good collagen levels is also a matter of what we eat that allows us to synthesize our own collagen (which includes: its ingredients, and various “helper” nutrients), as well as what dietary adjustments we make to avoid our extant collagen getting broken down, degraded, and generally lost.
Here’s what Dr. Suarez recommends:
Protein-rich foods (but watch out)
- Protein is essential for collagen production.
- Sources: fish, soy, lean meats (but not red meats, which—counterintuitively—degrade collagen), eggs, lentils.
- Egg whites are high in lysine, vital for collagen synthesis.
- Bone broth is a natural source of collagen.
Omega-3 fatty acids
- Omega-3s are anti-inflammatory and protect skin collagen.
- Sources: walnuts, chia seeds, flax seeds, fatty fish (e.g. mackerel, sardines).
Leafy greens
- Leafy dark green vegetables (e.g. kale, spinach) are rich in vitamins C and B9.
- Vitamin C is crucial for collagen synthesis and acts as an antioxidant.
- Vitamin B9 supports skin cell division and DNA repair.
Red fruits & vegetables
- Red fruits/vegetables (e.g. tomatoes, red bell peppers) contain lycopene, an antioxidant that protects collagen from UV damage (so, that aspect is mostly relevant for skin, but antioxidants are good things to have in all of the body in any case).
Orange-colored vegetables
- Carrots and sweet potatoes are rich in vitamin A, which helps in collagen repair and synthesis.
- Vitamin A is best from food, not supplements, to avoid potential toxicity.
Fruits rich in vitamin C
- Citrus fruits, kiwi, and berries are loaded with vitamin C and antioxidants, essential for collagen synthesis and skin health.
Soy
- Soy products (e.g. tofu, soybeans) contain isoflavones, which reduce inflammation and inhibit enzymes that degrade collagen.
- Soy is associated with lower risks of chronic diseases.
Garlic
- Garlic contains sulfur, taurine, and lipoic acid, important for collagen production and repair.
What to avoid:
- Reduce foods high in advanced glycation end products (AGEs), which damage collagen and promote inflammation.
- AGEs are found in fried, roasted, or grilled fatty proteinous foods (e.g. meat, including synthetic meat, and yes, including grass-fed nicely marketed meat—although processed meat such as bacon and sausages are even worse than steaks etc).
- Switch to cooking methods like boiling or steaming to reduce AGE levels.
- Processed foods, sugary pastries, and red meats contribute to collagen degradation.
General diet tips:
- Incorporate more plant-based, antioxidant-rich foods.
- Opt for slow cooking to reduce AGEs.
- Since sustainability is key, choose foods you enjoy for a collagen-boosting diet that you won’t seem like a chore a month later.

Elderly loss of energy
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 Q&A Day at 10almonds!
Have a question or a request? You can always hit “reply” to any of our emails, or use the feedback widget at the bottom!
In cases where we’ve already covered something, we might link to what we wrote before, but will always be happy to revisit any of our topics again in the future too—there’s always more to say!
As ever: if the question/request can be answered briefly, we’ll do it here in our Q&A Thursday edition. If not, we’ll make a main feature of it shortly afterwards!
So, no question/request too big or small
❝Please please give some information on elderly loss of energy and how it can be corrected. Please!❞
A lot of that is the metabolic slump described above! While we certainly wouldn’t describe 60 as elderly, and the health impacts from those changes at 45–55 get a gentler curve from 60 onwards… that curve is only going in one direction if we don’t take exceptionally good care of ourselves.
And of course, there’s also a degree of genetic lottery, and external factors we can’t entirely control (e.g. injuries etc).
One factor that gets overlooked a lot, though, is really easy to fix: B-vitamins.
In particular, vitamins B1, B5, B6, and B12. Of those, especially vitamins B1 and B12.
(Vitamins B5 and B6 are critical to health too, but relatively few people are deficient in those, while many are deficient in B1 and/or B12, especially as we get older)
Without going so detailed as to make this a main feature: these vitamins are essential for energy conversion from food, and they will make a big big difference.
You might especially want to consider taking sulbutiamine, which is a synthetic version of thiamin (vitamin B1), and instead of being water-soluble, it’s fat-soluble, and it easily crosses the blood-brain barrier, which is a big deal.
As ever, always check with your doctor because your needs/risks may be different. Also, there can be a lot of reasons for fatigue and you wouldn’t want to overlook something important.
You might also want to check out yesterday’s sponsor, as they offer personalized at-home health testing to check exactly this sort of thing.
❝What are natural ways to lose weight after 60? Taking into account bad knees or ankles, walking may be out as an exercise, running certainly is.❞
Losing weight is generally something that comes more from the kitchen than the gym, as most forms of exercise (except HIIT; see below) cause the metabolism to slow afterwards to compensate.
However, exercise is still very important, and swimming is a fine option if that’s available to you.
A word to the wise: people will often say “gentle activities, like tai chi or yoga”, and… These things are not the same.
Tai chi and yoga both focus on stability and suppleness, which are great, but:
- Yoga is based around mostly static self-support, often on the floor
- Tai chi will have you very often putting most of your weight on one slowly-increasingly bent knee at a time, and if you have bad knees, we’ll bet you winced while reading that.
So, maybe skip tai chi, or at least keep it to standing meditations and the like, not dynamic routines. Qigong, the same breathing exercises used in tai chi, is also an excellent way to improve your metabolism, by the way.
Ok, back onto HIIT:
