Our Verdict
When comparing physical sunscreens to chemical sunscreens, we picked the physical sunscreens.
Why?
It’s easy to vote against chemical sunscreens, because it has “chemical” in the name, which tends to be offputting PR-wise no matter how healthy something is.
But in this case, there’s actual science here too!
Physical sunscreens physically block the UV rays.
- On the simplest of levels, mud is a physical sunscreen, as you can see widely used by elephants, hippos, pigs, and other animals.
- On a more sophisticated level, modern physical sunscreens often use tiny zinc particles (or similar) to block the UV rays in a way that isn’t so obvious to the naked eye—so we can still see our skin, and it looks just like we applied an oil or other moisturizer.
Chemical sunscreens interact with the UV rays in a way that absorbs them.
- Specifically, they usually convert it into relatively harmless thermal energy (heat)
- However, this can cause problems if there’s too much heat!
- Additionally, chemical sunscreens can get “used up” in a way that physical sunscreens can’t* becoming effectively deactivated once the chemical reaction has run its course and there is no more reagent left unreacted.
- Worse, some of the reagents, when broken down by the UV rays, can potentially cause harm when absorbed by the skin.
*That said, physical sunscreens will still need “topping up” because we are a living organism and our body can’t resist redistributing and using stuff—plus, depending on the climate and our activities, we can lose some externally too.

Thai Green Curry With Crispy Tofu Balls
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.
Diversity is key here, with a wide range of mostly plants, offering an even wider range of phytochemical benefits:
You will need
- 7 oz firm tofu
- 1 oz cashew nuts (don’t soak them)
- 1 tbsp nutritional yeast
- 1 tsp turmeric
- 4 scallions, sliced
- 7 oz mangetout
- 7 oz fermented red cabbage (i.e., from a jar)
- 1 cup coconut milk
- Juice of ½ lime
- 2 tsp light soy sauce
- 1 handful fresh cilantro, or if you have the “cilantro tastes like soap” gene, then parsley
- 1 handful fresh basil
- 1 green chili, chopped (multiply per heat preference)
- 1″ piece fresh ginger, roughly chopped
- ¼ bulb garlic, crushed
- 1 tsp red chili flakes
- 1 tsp black pepper, coarse ground
- ½ tsp MSG or 1 tsp low-sodium salt
- Avocado oil for frying
- Recommended, to serve: lime wedges
- Recommended, to serve: your carbohydrate of choice, such as soba noodles or perhaps our Tasty Versatile Rice.
Method
(we suggest you read everything at least once before doing anything)
1) Heat the oven to 350℉ / 180℃, and bake the cashews on a baking tray for about 8 minutes until lightly toasted. Remove from the oven and allow to cool a little.
2) Combine the nuts, tofu, nutritional yeast, turmeric, and scallions in a food processor, and process until the ingredients begin to clump together. Shape into about 20 small balls.
3) Heat some oil in a skillet and fry the tofu balls, jiggling frequently to get all sides; it should take about 5 minutes to see them lightly browned. Set aside.
4) Combine the coconut milk, lime juice, soy sauce, cilantro/parsley, basil, scallions, green chili, ginger, garlic, and MSG/salt in a high-speed blender, and blend until a smooth liquid.
5) Transfer the liquid to a saucepan, and bring to the boil. Reduce the heat, add the mangetout, and simmer for about 5 minutes to reduce slightly. Stir in the red chili flakes and black pepper.
6) Serve with your preferred carbohydrate, adding the fermented red cabbage and the crispy tofu balls you set aside, along with any garnish you might like to add.
Enjoy!

*but not MSG or salt, as while they may in culinary terms get lumped in with spices, they are of course not plants. Nor is nutritional yeast (nor any other yeast, for that matter). However, mushrooms (not seen in this recipe, though to be honest they would be a respectable addition) would get included for a whole point per mushroom type, since while they are not technically plants but fungi, the nutritional profile is plantlike.

Reclaiming Body Trust – by Hilary Kinavey & Dana Sturtevant
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.
Authored by a therapist and a dietician, this book draws from both of their extensive professional clinical experiences, to explore how we can (often early in our lives) be led into disordered thinking when it comes to food and our bodies, and how we can “take back that which has been stolen from us”.
More prosaically: the presented goal here is for us to each figure out where we are with our own body, and how we might build our relationship with same going forwards, in the way that will work the best for us.
The style is relaxed and conversational, while taking care to cover topics that are often tricky with no less seriousness. Chapter headings such as “Your coping is rooted in wisdom”, “What does grief have to do with it?” and “Allowing for pleasure and satisfaction” give an idea of the flavors at hand here.
Bottom line: if you think your relationship with food and your body could be better, not only are you probably right, but also, this book can help.

How To Manage Your Mood With Food (8 Ways)
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 is hard to be mentally healthy for long without good diet. Food can not only affect our mood directly, but also indirectly because of how our brain works (or doesn’t, if we don’t have the right nutrients, or it is being sabotaged in some other dietary fashion).
Selecting the food for setting the mood
Mind, the mental health charity, have these advices to share (with some bonus notes of our own):
- Eat regularly: blood sugar peaks and troughs can heighten feelings of tiredness, irritability, or depression. Instead, enjoy foods that are high in energy but low in glycemic index, such as nuts, seeds, and oats—that way you’ll have plenty of energy, that lasts longer.
- Choose the right fats: omega-3 fatty acids are essential for the brain. So are omega-6 fatty acids, but it is rare to have a deficiency in omega-6, and indeed, many people have the ratio of omega-3 to omega-6 far too imbalanced in omega-6’s favor. So, focussing on getting more omega-3 fatty acids is important. Nuts and seeds are again great, as are avocados, eggs, and oily fish.
- Get a healthy amount of protein: and importantly, with a good mix of amino acids—so a variety of sources of protein is best. In particular, if you are vegan, paying attention to ensure you get a full spread of amino acids is critical, as not many plants have all the ones we need (soy does, though). The reason this is important for mood is because many of those amino acids double up as the building blocks of neurotransmitters, so they’re not entirely interchangeable.
- Stay hydrated: our bodies are famously made of mostly water, and our brain will not work well if it’s dehydrated. The human body can squeeze water out of almost anything that has water in it, but water from food (such as fruit, or soups) is best. If enjoying actual drinks, then herbal teas are excellent for hydration.
- Eat a rainbow of fruits and vegetables: these have many nutrients that are important for brain health, and the point of the colors is that most of those pigments are themselves nutrients. Additionally, the fiber content of fruits and vegetables is of topmost important for your heart, and as you’ll remember (we say it often, because it’s true): what’s good for your heart is good for your brain.
- Limit caffeine intake: for many people, excess caffeine can lead to feelings of anxiety, disrupt your sleep, and for everyone who has developed an addiction to it, it will cause withdrawal symptoms if stopped abruptly. Cutting back on caffeine, or even eliminating it, may improve your mood and sleep quality. Note, however, that if you have ADHD, then your brain’s physiological relationship with caffeine is a little different, and stimulants will be more beneficial (and less deleterious) for you than for most people. If unsure, speak with your doctor about this one.
- Support your gut health: because of the gut-brain axis (via the vagal nerve), and also because nearly all of our endogenous serotonin is made in the gut (along with other neurotransmitters/hormones), getting plenty of fiber is important, and probiotics can help too.
- Consider food intolerances: if you know you have one, then keep that in mind and tailor your diet accordingly. If you suspect you have one, seek a nutritionist’s help to find out for sure. These can affect many aspects of health, including mood, so should not be dismissed as a triviality.

❝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:

How To Triple Your Breast Cancer Survival Chances
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.
Keeping Abreast Of Your Cancer Risk
It’s the kind of thing that most people think won’t happen to them. And hopefully, it won’t!
But…
- Anyone (who has not had a double mastectomy*, anyway) can get breast cancer.
- *and even this depends on the type of double mastectomy and other circumstances, and technically there will always be a non-zero risk, because of complicating factors.
- Breast cancer, if diagnosed early (before it spreads), has a 98% survival rate.
- That survival rate drops to 31% if diagnosed after it has spread through the body.
(The US CDC’s breast cancer “stat bite” page has more stats and interactive graphs, so click here to see those charts and get the more detailed low-down on mortality/survival rates with various different situations)
We think that the difference between 98% and 31% survival rates is more than enough reason to give ourselves a monthly self-check at the very least! You’ve probably seen how-to diagrams before, but here are instructions for your convenience:
(This graphic was created by the Jordan Breast Cancer Program—check them out, as they have lots of resources)
If you don’t have the opportunity to take matters into your own hands right now, rather than just promise yourself “I’ll do that later”, take this free 4-minute Breast Health Assessment from Aurora Healthcare. Again, we think the difference early diagnosis can make to your survival chances make these tests well worth it:

Lest we forget, men can also get breast cancer (the CDC has a page for men too), especially if over 50. But how do you check for breast cancer, when you don’t have breasts in the commonly-understood sense of the word?
So take a moment to do this (yes, really actually do it!), and set a reminder in your calendar to repeat it monthly—there really is no reason not to!
Take care of yourself; you’re important.

Making Friends With Your Gut (You Can Thank Us Later)

Gut Health 101
We have so many microorganisms inside us, that by cell count, their cells outnumber ours more than ten-to-one. By gene count, we have 23,000 and they have more than 3,000,000. In effect, we are more microbe than we are human. And, importantly: they form a critical part of what keeps our overall organism ticking on.
Read all about it: The role of the gut microbiota in nutrition and health
Our trillions of tiny friends keep us alive, so it really really pays to return the favor.
But how?
Probiotics and fermented foods
You probably guessed this one, but it’d be remiss not to mention it first. It’s no surprise that probiotics help; the clue is in the name. In short, they help add diversity to your microbiome (that’s a good thing).
Read from the NIH: Probiotics: What You Need To Know
As for fermented foods, not every fermented food will boost your microbiota, but great options include…
- Fermented vegetables (sauerkraut, pickles, etc)
- You’ll often hear kimchi mentioned; that is also pickled vegetables, usually mostly cabbage. It’s just the culinary experience that differs. Unlike sauerkraut, kimchi is usually spiced, for example.
- Kombucha (a fermented sweet tea)
- Miso & tempeh (different preparations of fermented soy)
The health benefits vary based on the individual strains of bacteria involved in the fermentation, so don’t get too caught up on which is best.
The best one is the one you enjoy, because then you’ll have it regularly!
Feed them plenty of prebiotic fibers
Those probiotics you took? The bacteria in them eat the fiber that you can’t digest without them. So, feed them those sorts of fibers.
Great options include:
- Bananas
- Garlic
- Onions
- Whole grains

Don’t feed them sugar and sweeteners
Sugar and (and, counterintuitively, aspartame) can cause unfortunate gut microbe imbalances. Put simply, they kill some of your friends and feed some of your enemies. For example…
Candida, which we all have in us to some degree, feeds on sugar (including the sugar formed from breaking down alcohol, by the way) and refined carbs. Then it grows, and puts its roots through your intestinal walls, linking with your neural system. Then it makes you crave the very things that will feed it and allow it to put bigger holes in your intestinal walls.
Do not feed the Candida.
Don’t believe us? Read: Candida albicans-Induced Epithelial Damage Mediates Translocation through Intestinal Barriers
(That’s scientist-speak for “Candida puts holes in your intestines, and stuff can then go through those holes”)
And as for how that comes about, it’s like we said:
❝Colonization of the intestine and translocation through the intestinal barrier are fundamental aspects of the processes preceding life-threatening systemic candidiasis. In this review, we discuss the commensal lifestyle of C. albicans in the intestine, the role of morphology for commensalism, the influence of diet, and the interactions with bacteria of the microbiota.❞
Source: Candida albicans as a commensal and opportunistic pathogen in the intestine
The usual five things
- Good diet (Mediterranean Diet is good; plant-based version of it is by far the best for this)
- Good exercise (yes, really)
- Good sleep (helps them, and they’ll help you get better sleep in return)
- Limit or eliminate alcohol consumption (what a shocker)
- Don’t smoke (it’s bad for everything, including gut health)
One last thing you should know:
If you’re used to having animal products in your diet, and make a sudden change to all plants, your gut will object very strongly. This is because your gut microbiome is used to animal products, and a plant-based diet will cause many helpful microbes to flourish in great abundance, and many less helpful microbes will starve and die. And they will make it officially Not Fun™ for you.
So, you have two options to consider:
- Do it anyway, and sit it out (and believe us, you’ll be sitting), get the change over with quickly, and enjoy the benefits and much happier gut that follows.
- Make the change gradual. Reduce portions of animal products slowly, have “Meatless Mondays” etc, and slowly make the change over. This—for most people—is pretty comfortable, easy, and effective.
And remember: the effects of these things we’ve talked about today compound when you do more than one of them, but if you don’t want to take probiotics or really hate kombucha or absolutely won’t consider a plant-based diet or struggle to give up sugar or alcohol, etc… Just do what you can do, and you’ll still have a net improvement!
