“Diet will fix your brain” is a bold claim that often comes from wishful thinking and an optimistic place where anecdote is louder than evidence. But, diet does incontrovertibly also affect brain health. So, what does Dr. Naidoo bring to the table?
The author is a Harvard-trained psychiatrist, a professional chef who graduated with her culinary school’s most coveted award, and a trained-and-certified nutritionist. Between those three qualifications, it’s safe to she knows her stuff when it comes to the niche that is nutritional psychiatry. And it shows.
She takes us through the neurochemistry involved, what chemicals are consumed, made, affected, inhibited, upregulated, etc, what passes through the blood-brain barrier and what doesn’t, what part the gut really plays in its “second brain” role, and how we can leverage that—as well as mythbusting a lot of popular misconceptions about certain foods and moods.
There’s hard science in here, but presented in quite a pop-science way, making for a very light yet informative read.
Bottom line: if you’d like to better understand what your food is doing to your brain (and what it could be doing instead), then this is a top-tier book for you!

Top 8 Fruits That Prevent & Kill Cancer
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. Amy Dee, pharmacist and cancer survivor herself, lays out the best options for anticancer fruits:
The fruits
Without further ado, they are:
- Kiwi: promotes cancer cell death while sparing healthy cells
- Plums & peaches: an interesting choice to list these similar fruits together as one item, but they both also induce cell death in cancer cells while sparing healthy ones
- Dragon fruit: this does the same, while also inhibiting cancer cell growth
- Figs: these have antitumor effects specifically, while removing carcinogens too, and additionally sensitizing cancer cells to light therapy
- cranberries: disrupt cancer cell adhesion, breaking down tumors, while protecting non-cancerous cells against DNA damage
- citrus fruits: inhibit tumor growth and kill cancer cells; regular consumption is also associated with a lower cancer risk (be warned though, grapefruit interacts with some medications)
- cherries: induce cancer cell death; protect healthy cells against DNA damage
- tomatoes: don’t often make it into lists of fruits, but lycopene reduces cancer risk, and slows the growth of cancer cells (10almonds note: watermelon has more lycopene than tomatoes, and is more traditionally considered a fruit in all respects, so could have taken the spot here).
We would also argue that apricots could have had a spot on the list, both for their lycopene content (comparable to tomatoes) and their botanical (and this phytochemical) similarities to peaches and plums.
For more information on each of these (she also talks about the different polyphenols and other nutrients that constitute the active compounds delivering these anticancer effects), enjoy:

The Lymphatic System Against Cancer & More
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.
Ask Not What Your Lymphatic System Can Do For You…
Just kidding; we’ll cover that first, as it’s definitely not talked about enough.
The lymphatic system is the system in the body that moves lymph around. It’s made of glands, nodes, and vessels:
- The glands (such as the tonsils and the adenoids) and nodes filter out bacteria and produce white blood cells. Specific functions may be, well, specialized—beyond the scope of today’s article—but that’s the broad function.
- The vessels are the tubes that allow those things to be moved around, suspended in lymph.
What’s lymph? It’s a colorless water-like liquid that transports immune cells, nutrients (and waste) around the body (through the lymphatic system).
Yes, it works alongside your vasculature; when white blood cells aren’t being deployed en masse into your bloodstream to deal with some threat, they’re waiting in the wings in the lymphatic system.
While your blood is pumped around by your heart, lymph moves based on a variety of factors, including contractions of small specialized lymphatic muscles, the pressure gradient created by the combination of those and gravity, and the movements of your body itself.
Here’s a larger article than we have room for, with diagrams we also don’t have room for:
Modelling the lymphatic system
To oversimplify it in few words for the sake of moving on: you can most of the time: think of it as an ancillary network supporting your circulatory system that unlike blood, doesn’t deal with oxygen or sugars, but does deal with a lot of other things, including:
- water and salt balance
- immune cells and other aspects of immune function
- transports fats (and any fat-soluble vitamins in them) into circulation
- cleans up stuff that gets stuck between cells
- general detoxification
There’s a lot that can go wrong if lymph isn’t flowing as it should
Too much to list here, but to give an idea:
- Arthritis and many autoimmune diseases
- Cardiovascular disease and metabolic syndrome
- Obesity, diabetes, and organ failure
- Alzheimer’s and other dementias
- Lymphadenitis, lymphangitis, and lymphedenopathy
- Lymphomas and Hodgkin’s disease (both are types of lymphatic cancer)
- Cancers of other kinds, because of things not being cleaned up where and when they should be
Yikes! That’s a lot of important things for a mostly-forgotten system to be taking care of protecting us from!
What you can do for your lymphatic system, to avoid those things!
Happily, there are easy things we can do to give our lymph some love, such as:
Massage therapy (and foam rolling)
This is the go-to that many people/publications recommend. It’s good! It’s certainly not the most important thing to do, but it’s good.
You can even use a simple gadget like this one to help move the lymph around, without needing to learn arcane massage techniques.
Exercise (move your body!)
This is a lot more important. The more we move our body, the more lymph moves around. The more lymph moves around today, the more easily it will move around tomorrow. A healthy constant movement of lymph throughout the lymphatic system is key to keeping everything running smoothly.
If you pick only one kind of exercise, make it High-Intensity Interval Training (HIIT):
How To Do HIIT (Without Wrecking Your Body)
If for some reason you really can’t do that, just spend as much of your waking time as reasonably possible, moving, per:
For ideas on how to do that, check out…
Get thee to a kitchen
This is about getting healthy food that gives your body’s clean-up crew (the lymphatic system) an easier time of it.
Rather than trying to “eat clean” which can be a very nebulous term and it’s often not at all clear (and/or hotly debated) what counts as “clean”, instead, stick to foods that constitute an anti-inflammatory diet:

Brown Rice vs Wild Rice – 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 brown rice to wild rice, we picked the wild.
Why?
It’s close! But there are important distinctions.
First let’s clarify: despite the name and appearance, wild rice is botanically quite different from rice per se; it’s not the same species, it’s not even the same genus, though it is the same umbrella family. In other words, they’re about as closely related as humans and gorillas are to each other.
In terms of macros, wild rice has considerably more protein and a little more fiber, for slightly lower carbs.
Notably, however, wild rice’s carbs are a close-to-even mix of sucrose, fructose, and glucose, while brown rice’s carbs are 99% starch. Given the carb to fiber ratio, it’s worth noting that wild rice also has lower net carbs, and the lower glycemic index.
In the category of vitamins, wild rice leads with more of vitamins A, B2, B9, E, K, and choline. In contrast, brown rice has more of vitamins B1, B3, and B5. So, a moderate win for wild rice.
When it comes to minerals, brown rice finally gets a tally in its favor, even if only slightly: brown rice has more magnesium, manganese, phosphorus, and selenium, while wild rice has more copper, potassium, and zinc. They’re equal in calcium and iron, by the way. Still, this category stands as a 4:3 win for brown rice.
Adding up the categories makes a modest win for wild rice, and additionally, if we had to consider one of these things more important than the others, it’d be wild rice being higher in fiber and protein and lower in total carbs and net carbs.
Still, enjoy either or both, per your preference!

America Worries About Health Costs — And Voters Want to Hear From Biden and Republicans
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.
President Joe Biden is counting on outrage over abortion restrictions to help drive turnout for his reelection. Former President Donald Trump is promising to take another swing at repealing Obamacare.
But around America’s kitchen tables, those are hardly the only health topics voters want to hear about in the 2024 campaigns. A new KFF tracking poll shows that health care tops the list of basic expenses Americans worry about — more than gas, food, and rent. Nearly 3 in 4 adults — and majorities of both parties — say they’re concerned about paying for unexpected medical bills and other health costs.
“Absolutely health care is something on my mind,” Rob Werner, 64, of Concord, New Hampshire, said in an interview at a local coffee shop in January. He’s a Biden supporter and said he wants to make sure the Affordable Care Act, also known as Obamacare, is retained and that there’s more of an effort to control health care costs.
The presidential election is likely to turn on the simple question of whether Americans want Trump back in the White House. (Nikki Haley, the former South Carolina governor and U.S. ambassador to the United Nations, remained in the race for the Republican nomination ahead of Super Tuesday, though she had lost the first four primary contests.) And neither major party is basing their campaigns on health care promises.
But in the KFF poll, 80% of adults said they think it’s “very important” to hear presidential candidates talk about what they’d do to address health care costs — a subject congressional and state-level candidates can also expect to address.
“People are most concerned about out-of-pocket expenses for health care, and rightly so,” said Andrea Ducas, vice president of health policy at the Center for American Progress, a Washington, D.C.-based progressive think tank.
Here’s a look at the major health care issues that could help determine who wins in November.
Abortion
Less than two years after the Supreme Court overturned the constitutional right to an abortion, it is shaping up to be the biggest health issue in this election.
That was also the case in the 2022 midterm elections, when many voters rallied behind candidates who supported abortion rights and bolstered Democrats to an unexpectedly strong showing. Since the Supreme Court’s decision, voters in six states — including Kansas, Kentucky, and Ohio, where Republicans control the legislatures — have approved state constitutional amendments protecting abortion access.
Polls show that abortion is a key issue to some voters, said Robert Blendon, a public opinion researcher and professor emeritus at the Harvard T.H. Chan School of Public Health. He said up to 30% across the board see it as a “personal” issue, rather than policy — and most of those support abortion rights.
“That’s a lot of voters, if they show up and vote,” Blendon said.
Proposals to further protect — or restrict — abortion access could drive voter turnout. Advocates are working to put abortion-related measures on the ballot in such states as Arizona, Florida, Missouri, and South Dakota this November. A push in Washington toward a nationwide abortion policy could also draw more voters to the polls, Blendon said.
A surprise ruling by the Alabama Supreme Court in February that frozen embryos are children could also shake up the election. It’s an issue that divides even the anti-abortion community, with some who believe that a fertilized egg is a unique new person deserving of full legal rights and protections, and others believing that discarding unused embryos as part of the in vitro fertilization process is a morally acceptable way for couples to have children.
Pricey Prescriptions
Drug costs regularly rank high among voters’ concerns.
In the latest tracking poll, more than half — 55% — said they were very worried about being able to afford prescription drugs.
Biden has tried to address the price of drugs, though his efforts haven’t registered with many voters. While its name doesn’t suggest landmark health policy, the Inflation Reduction Act, or IRA, which the president signed in August 2022, included a provision allowing Medicare to negotiate prices for some of the most expensive drugs. It also capped total out-of-pocket spending for prescription drugs for all Medicare patients, while capping the price of insulin for those with diabetes at $35 a month — a limit some drugmakers have extended to patients with other kinds of insurance.
Drugmakers are fighting the Medicare price negotiation provision in court. Republicans have promised to repeal the IRA, arguing that forcing drugmakers to negotiate lower prices on drugs for Medicare beneficiaries would amount to price controls and stifle innovation. The party has offered no specific alternative, with the GOP-led House focused primarily on targeting pharmacy benefit managers, the arbitrators who control most Americans’ insurance coverage for medicines.
Costs of Coverage
Health care costs continue to rise for many Americans. The cost of employer-sponsored health plans have hit new highs in the past few months, raising costs for employers and workers alike. Experts have attributed the increase to high demand and expensive prices for certain drugs and treatments, notably weight loss drugs, as well as to medical inflation.
Meanwhile, the ACA is popular. The KFF poll found that more adults want to see the program expanded than scaled back. And a record 21.3 million people signed up for coverage in 2024, about 5 million of them new customers.
Enrollment in Republican-dominated states has grown fastest, with year-over-year increases of 80% in West Virginia, nearly 76% in Louisiana, and 62% in Ohio, according to the Centers for Medicare & Medicaid Services.
Public support for Obamacare and record enrollment in its coverage have made it politically perilous for Republicans to pursue the law’s repeal, especially without a robust alternative. That hasn’t stopped Trump from raising that prospect on the campaign trail, though it’s hard to find any other Republican candidate willing to step out on the same limb.
“The more he talks about it, the more other candidates have to start answering for it,” said Jarrett Lewis, a partner at Public Opinion Strategies, a GOP polling firm.
“Will a conversation about repeal-and-replace resonate with suburban women in Maricopa County?” he said, referring to the populous county in Arizona known for being a political bellwether. “I would steer clear of that if I was a candidate.”
Biden and his campaign have pounced on Trump’s talk of repeal. The president has said he wants to make permanent the enhanced premium subsidies he signed into law during the pandemic that are credited with helping to increase enrollment.
Republican advisers generally recommend that their candidates promote “a market-based system that has the consumer much more engaged,” said Lewis, citing short-term insurance plans as an example. “In the minds of Republicans, there is a pool of people that this would benefit. It may not be beneficial for everyone, but attractive to some.”
Biden and his allies have criticized short-term insurance plans — which Trump made more widely available — as “junk insurance” that doesn’t cover care for serious conditions or illnesses.
Entitlements Are Off-Limits
Both Medicaid and Medicare, the government health insurance programs that cover tens of millions of low-income, disabled, and older people, remain broadly popular with voters, said the Democratic pollster Celinda Lake. That makes it unlikely either party would pursue a platform that includes outright cuts to entitlements. But accusing an opponent of wanting to slash Medicare is a common, and often effective, campaign move.
Although Trump has said he wouldn’t cut Medicare spending, Democrats will likely seek to associate him with other Republicans who support constraining the program’s costs. Polls show that most voters oppose reducing any Medicare benefits, including by raising Medicare’s eligibility age from 65. However, raising taxes on people making more than $400,000 a year to shore up Medicare’s finances is one idea that won strong backing in a recent poll by The Associated Press and NORC Center for Public Affairs Research.
Brian Blase, a former Trump health adviser and the president of Paragon Health Institute, said Republicans, if they win more control of the federal government, should seek to lower spending on Medicare Advantage — through which commercial insurers provide benefits — to build on the program’s efficiencies and ensure it costs taxpayers less than the traditional program.
So far, though, Republicans, including Trump, have expressed little interest in such a plan. Some of them are clear-eyed about the perils of running on changing Medicare, which cost $829 billion in 2021 and is projected to consume nearly 18% of the federal budget by 2032.
“It’s difficult to have a frank conversation with voters about the future of the Medicare program,” said Lewis, the GOP pollster. “More often than not, it backfires. That conversation will have to happen right after a major election.”
Addiction Crisis
Many Americans have been touched by the growing opioid epidemic, which killed more than 112,000 people in the United States in 2023 — more than gun deaths and road fatalities combined. Rural residents and white adults are among the hardest hit.
Federal health officials have cited drug overdose deaths as a primary cause of the recent drop in U.S. life expectancy.
Republicans cast addiction as largely a criminal matter, associating it closely with the migration crisis at the U.S. southern border that they blame on Biden. Democrats have sought more funding for treatment and prevention of substance use disorders.
“This affects the family, the neighborhood,” said Blendon, the public opinion researcher.
Billions of dollars have begun to flow to states and local governments from legal settlements with opioid manufacturers and retailers, raising questions about how to best spend that money. But it isn’t clear that the crisis, outside the context of immigration, will emerge as a campaign issue.

Our Top 5 Spices: How Much Is Enough For Benefits?
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.
A spoonful of pepper makes the… Hang on, no, that’s not right…
We know that spices are the spice of life, and many have great health-giving qualities. But…
- How much is the right amount?
- What’s the minimum to get health benefits?
- What’s the maximum to avoid toxicity?
That last one always seems like a scary question, but please bear in mind: everything is toxic at a certain dose. Oxygen, water, you-name-it.
On the other hand, many things have a toxicity so low that one could not physically consume it sufficiently faster than the body eliminates it, to get a toxic build-up.
Consider, for example, the €50 banknote that was nearly withdrawn from circulation because one of the dyes used in it was found to be toxic. However, the note remained in circulation after scientists patiently explained that a person would have to eat many thousands of them to get a lethal dose.
So, let’s address these questions in reverse order:
What’s the maximum to avoid toxicity?
In the case of the spices we’ll look at today, the human body generally* has high tolerance for them if eaten at levels that we find comfortable eating.
*IMPORTANT NOTE: If you have (or may have) a medical condition that may be triggered by spices, go easier on them (or if appropriate, abstain completely) after you learn about that.
Check with your own physician if unsure, because not only are we not doctors, we’re specifically not your doctors, and cannot offer personalized health advice.
We’re going to be talking in averages and generalizations here. Caveat consumator.
For most people, unless you are taking the spice in such quantities that you are folding space and seeing the future, or eating them as the main constituents of your meal rather than an embellishment, you should be fine. Please don’t enter a chilli-eating contest and sue us.
What is the minimum to get health benefits and how much should we eat?
The science of physiology generally involves continuous rather than discrete data, so there’s not so much a hard threshold, as a point at which the benefits become significant. The usefulness of most nutrients we consume, be they macro- or micro-, will tend to have a bell curve.
In other words, a tiny amount won’t do much, the right amount will have a good result, and usefulness will tail off after that point. To that end, we’re going to look at the “sweet spot” of peaking on the graph.
Also note: the clinical dose is the dose of the compound, not the amount of the food that one will need to eat to get that dose. For example, food x containing compound y will not usually contain that compound at 100% rate and nothing else. We mention this so that you’re not surprised when we say “the recommended dose is 5mg of compound, so take a teaspoon of this spice”, for example.
Further note: we only have so much room here, so we’re going to list only the top benefits, and not delve into the science of them. You can see the related main features for more details, though!
The “big 5” health-giving spices, with their relevant active compound:
- Black pepper (piperine)
- Hot pepper* (capsaicin)
- Garlic (allicin)
- Ginger (gingerol)
- Turmeric (curcumin**)
*Cayenne pepper is very high in capsaicin; chilli peppers are also great
**not the same thing as cumin, which is a completely different plant. Cumin does have some health benefits of its own, but not in the same league as the spices above, and there’s only so much we have room to cover today.
Black pepper
- Benefits: antioxidant, anti-cancer, boosts bioavailability of other nutrients, aids digestion
- Dosage: 5–20mg for benefits
- Suggestion: ½ teaspoon of black pepper is sufficient for benefits. However, this writer’s kitchen dictum in this case is “if you can’t see the black pepper in/on the food, add more”—but that’s more about taste!
- Related main feature: Black Pepper’s Anti-Cancer Arsenal (And More)
Hot Pepper
- Benefits: anti-inflammatory, metabolism accelerator
- Dosage: 6mg gives benefits, 500mg is a common dose in capsules
- Suggestion: if not making a spicy dish, consider using a teaspoon of cayenne as part of the seasoning for rice or potatoes
- Related main feature: Capsaicin For Weight Loss And Against Inflammation
Garlic
- Benefits: heart health, blood sugar balancing, anti-cancer
- Dosage: 4–8µg for benefits
- Suggestion: 1–2 cloves daily is generally good. However, cooking reduces allicin content (and so does oxidation after cutting/crushing), so you may want to adjust accordingly if doing those things.
- Related main feature: The Many Health Benefits Of Garlic
Ginger
- Benefits: anti-inflammatory, antioxidant, anti-nausea
- Dosage: 3–4g for benefits
- Suggestion: 1 teaspoon grated raw ginger or ½ a teaspoon powdered ginger, can be used in baking or as part of the seasoning for a stir-fry
- Related main feature: Ginger Does A Lot More Than You Think
Turmeric
- Benefits: anti-inflammatory, anti-cancer
- Dosage: 500–2000mg for benefits
- Suggestion: ¼ teaspoon per day is sufficient for benefits; ½ teaspoon dropped into the water when cooking rice will infuse the rice with turmeric (which is very water-soluble), turn the rice a pretty golden color, and not affect the flavor. Throw in some black pepper as it increases the bioavailability of curcumin up to 2000%
- Related main feature: Why Curcumin (Turmeric) Is Worth Its Weight In Gold
Closing notes
The above five spices are very healthful for most people. Personal physiology can and will vary, so if in doubt, a) check with your doctor b) start at lowest doses and establish your tolerance (or lack thereof).
Enjoy, and stay well!

Beet “Kvass” With Ginger
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.
Kvass is a popular drink throughout Eastern Europe, with several countries claiming it, but the truth is, kvass is older than nations (as in: nations, in general, any of them; nation states are a newer concept than is often realized), and its first recorded appearance was in the city state of Kyiv.
This one is definitely not a traditional recipe, as kvass is usually made from rye, but keeping true to its Eastern European roots with (regionally popular) beetroot, it’s nevertheless a great fermented drink, full of probiotic benefits, and this time, with antioxidants too.
It’s a little saltier than most things we give recipes for here, so enjoy it on hot sunny days as a great way to replenish electrolytes!
You will need (for 1 quart / 1 liter)
- 2¾ cups filtered or spring water
- 2 beets, roughly chopped
- 1 tbsp chopped fresh ginger
- 2 tsp salt (do not omit or substitute)
Method
(we suggest you read everything at least once before doing anything)
1) Sterilize a 1-quart jar with boiling water (carefully please)
2) Put all the ingredients in the jar and stir until the salt dissolves
3) Close the lid tightly and store in a cool dark place to ferment for 2 weeks
4) Strain the beets and ginger (they are now pickled and can be enjoyed in a salad or as a kimchi-like snack), pouring the liquid into a clean jar/bottle. This can be kept in the fridge for up to a month. Next time you make it, if you use ¼ cup of this as a “starter” to replace an equal volume of water in the original recipe, the fermentation will take days instead of weeks.
5) Serve! Best served chilled, but without ice, on a hot sunny day.
Enjoy!
