The Healthiest Drumstick
Moringa oleifera is a tree, whose leaves and pods have medicinal properties (as well as simply being very high in nutrients). It’s also called the drumstick tree in English, but equally often it’s referred to simply as Moringa. It has enjoyed use in traditional medicine for thousands of years, and its many benefits have caught scientists’ attention more recently. For an overview before we begin, see:
Now, let’s break it down…
Anti-inflammatory
It is full of antioxidants, which we’ll come to shortly, and they have abundant anti-inflammatory effects. Research into these so far has mostly beennon-human animal studies or else in vitro, hence the guarded “potential” for now:
Potential anti-inflammatory phenolic glycosides from the medicinal plant Moringa oleifera fruits
Speaking of potential though, it has been found to also reduce neuroinflammation specifically, which is good, because not every anti-inflammatory agent does that:
Antioxidant
It was hard to find studies that talked about its antioxidant powers that didn’t also add “and this, and this, and this” because of all its knock-on benefits, for example:
❝The results indicate that this plant possesses antioxidant, hypolipidaemic and antiatherosclerotic activities and has therapeutic potential for the prevention of cardiovascular diseases.
These effects were at degrees comparable to those of simvastatin.❞
~ Dr. Pilaipark Chumark et al.
Likely a lot of its benefits in these regards come from the plant’s very high quercetin content, because quercetin does that too:
Quercetin reduces blood pressure in hypertensive subjects

Antidiabetic
It also has been found to lower fasting blood sugar levels by 13.5%:
Anti-arsenic?
We put a question mark there, because studies into this have only been done with non-human animals such as mice and rats so far, largely because there are not many human volunteers willing to sign up for arsenic poisoning (and no ethics board would pass it anyway).
However, as arsenic contamination in some foods (such as rice) is a big concern, this is very promising. Here are some example studies, with mice and rats respectively:
- Protective effects of Moringa oleifera Lam. leaves against arsenic-induced toxicity in mice
- Therapeutic effects of Moringa oleifera on arsenic-induced toxicity in rats
Is it safe?
A popular food product through parts of Africa and (especially) South & West Asia, it has a very good safety profile. Generally the only health-related criticism of it is that it contains some anti-nutrients (that hinder bioavailability of its nutrients), but the nutrients outweigh the antinutrients sufficiently to render this a trifling trivium.
In short: as ever, do check with your doctor/pharmacist to be sure, but in general terms, this is about as safe as most vegan whole foods; it just happens to also be something of a superfood, which puts it into the “nutraceutical” category. See also:

The Dangers Of Fires, Floods, & Having Your Hair Washed
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 a dangerous business, going out of your door… And this week’s news round-up looks at 5 reasons why that might be:
Superspreading like wildfire
Environmental health risks are a big topic these days, with our changing climate. As for wildfires? Some of the risks are obvious: burning to death or choking to death in the smoke—but even upon surviving the seemingly worst, more threats remain that themselves can still kill.
Those threats include that both burns and smoke inhalation can cause acute and chronic changes in the immune system. Specifically: changes for the worse. The mechanisms by which this happens depend on the nature of any burns received, and in the case of smoke, what exactly was in the smoke. Now, there is no kind of smoke that is healthy to inhale, but definitely some kinds are a lot worse than others, and let’s just say, people’s homes contain a lot of plastic.
Additionally, if you think someone coughing near you spreads germs, imagine how far germs can be spread by miles-high, miles-wide billowing hot air.
In short, there’s a lot going on and none of it is good, and we’ve barely had room to summarise here, so…

A flood of diseases
*record scratch*
Environmental health risks are a big topic these days, with our changing climate. As for floods? Some of the risks are obvious: drowning to death or having your house washed away—but even upon surviving the seemingly worst, more threats remain that themselves can still kill.
Those threats include increases in deaths from infectious and parasitic diseases, and respiratory diseases in general. Simply, a place that has been waterlogged, even if it seems “safe” now, is not a healthy place to be, due to bacteria, viruses, fungi, and more. In fact, it even increases all-cause mortality, because being healthy in such a place is simply harder:

Don’t lose your head
Visiting the hairdresser is not something that most people consider a potential brush with death—your hairdresser is probably not Sweeney Todd, after all. However…
There is an issue specifically with getting your hair washed there. Backwash basins—the sink things into which one rests one’s head at a backwards tilt—create an awkward angle for the cervical vertebrae and a sudden reduction in blood flow to the brain can cause a stroke, with the risk being sufficiently notable as to have its own name in scientific literature: beauty parlor stroke syndrome (BPSS).
❝While research suggests BPSS is most likely to occur in women over 50—and previous history of narrowing or thinning of blood vessels and arthritis of the spinal column in the neck are particular risk factors—it could happen to anyone regardless of age or medical history.❞

The smartwatch wristbands that give you cancer
It’s about the PFAS content. The article doesn’t discuss cancer in detail, just mentioning the increased risk, but you can read about the link between the two in our article below.
Basically, if your smartwatch wristband is a) not silicone and b) waterproof anyway, especially if it’s stain-resistant (as most are designed to be, what with wearing it next to one’s skin all the time while exercising, and not being the sort of thing one throws in the wash), then chances are it has PFAS levels much higher than normally found in consumer goods or clothing.

The cows giving milk with a little extra
Bird flu (HPAI) is now not the only flu epidemic amongst cattle in the US, and not only that, but rather than “merely” colonizing the lungs and upper respiratory tracts, in this case the virus (IAV) is thriving in the mammary glands, meaning that yes, it gets dispensed into the milk, and so far scientists are simply scrambling to find better ways to vaccinate the cattle, in the hopes that the milk will not be so risky because yes, it is currently a “reservoir and transmission vector” for the virus.
There are, however, barriers to creating those vaccines:

The Secret To Better Squats: Foot, Knee, & Ankle Mobility
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 talked before about how Slav squats, Asian squats, deep squats, sitting squats, or various other things they might by called (these are all different names for the same thing), are one of the most anti-aging exercises, if not outright the most anti-aging exercise. Yet, how to get good at them?
“Just squat more” is fine advice and will get you there eventually, but there are ways to shorten the time it takes, by unlocking whatever part(s) might be holding you back:
Piece by piece
The key to improving the whole is to not neglect any of the parts—so here they are:
- Foot rolls: roll your foot onto its outer and inner edges to stretch; repeat for both legs.
- Toe lifts: lift your toes up and down while keeping your legs straight.
- Toe curls: curl your toes to engage foot muscles.
- Foot circles: rotate your feet in circles; repeat for both legs.
- Heel raises: stand tall, raise your heels off the ground, and engage your core.
- Tibialis anterior exercise: lean against a wall or similar, and lift your toes off ground to strengthen your tibialis anterior (important and oft-forgotten muscle, responsible for more than people think!)
- Heel drops: perform dynamic heel drops with your feet back, to stretch your ankles.
- Hamstring curls & leg extension: curl your leg back toward your glutes, and then extend it forwards; alternate legs.
- Dynamic calf stretch: bend and straighten your knees alternately in a forward lunge position.
- Squat to heel raise: perform squats with your heels lifting off the floor and your arms raised.
- Banded ankle dorsiflexion: use a yoga strap or towel to stretch your feet, calves, and hamstrings.
- Seated feet circles: extend your legs and rotate your feet in outward and inward circles.
- Dorsiflexion/plantar flexion: alternate one foot up and the other down dynamically.
- Seated knee flexion & extension: alternate lifting your knees and extending your legs, while seated.
Note: “seated” in all cases means on the floor, not a chair!

Yes, you do need to clean your tongue. Here’s how and why
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.
Has your doctor asked you to stick out your tongue and say “aaah”? While the GP assesses your throat, they’re also checking out your tongue, which can reveal a lot about your health.
The doctor will look for any changes in the tongue’s surface or how it moves. This can indicate issues in the mouth itself, as well as the state of your overall health and immunity.
But there’s no need to wait for a trip to the doctor. Cleaning your tongue twice a day can help you check how your tongue looks and feels – and improve your breath.
luisrsphoto/Shutterstock What does a healthy tongue look like?
Our tongue plays a crucial role in eating, talking and other vital functions. It is not a single muscle but rather a muscular organ, made up of eight muscle pairs that help it move.
The surface of the tongue is covered by tiny bumps that can be seen and felt, called papillae, giving it a rough surface.
These are sometimes mistaken for taste buds – they’re not. Of your 200,000-300,000 papillae, only a small fraction contain taste buds. Adults have up to 10,000 taste buds and they are invisible to the naked eye, concentrated mainly on the tip, sides and back of the tongue. https://www.youtube.com/embed/uYvpUl7li9Y?wmode=transparent&start=0
A healthy tongue is pink although the shade may vary from person to person, ranging from dark to light pink.
A small amount of white coating can be normal. But significant changes or discolouration may indicate a disease or other issues.
How should I clean my tongue?
Cleaning your tongue only takes around 10-15 seconds, but it’s is a good way to check in with your health and can easily be incorporated into your teeth brushing routine.
Build-up can occur if you stop brushing or scraping your tongue even for a few days. Anthony Shkraba/Pexels You can clean your tongue by gently scrubbing it with a regular toothbrush. This dislodges any food debris and helps prevent microbes building up on its rough textured surface.
Or you can use a special tongue scraper. These curved instruments are made of metal or plastic, and can be used alone or accompanied by scrubbing with your toothbrush.
Your co-workers will thank you as well – cleaning your tongue can help combat stinky breath. Tongue scrapers are particularly effective at removing the bacteria that commonly causes bad breath, hidden in the tongue’s surface.
What’s that stuff on my tongue?
So, you’re checking your tongue during your twice-daily clean, and you notice something different. Noting these signs is the first step. If you observe any changes and they worry you, you should talk to your GP.
Here’s what your tongue might be telling you.
White coating
Developing a white coating on the tongue’s surface is one of the most common changes in healthy people. This can happen if you stop brushing or scraping the tongue, even for a few days.
In this case, food debris and microbes have accumulated and caused plaque. Gentle scrubbing or scraping will remove this coating. Removing microbes reduces the risk of chronic infections, which can be transferred to other organs and cause serious illnesses.
Scrubbing or scraping your tongue only takes around ten seconds and can be done while brushing your teeth. Ketut Subiyanto/Pexels Yellow coating
This may indicate oral thrush, a fungal infection that leaves a raw surface when scrubbed.
Oral thrush is common in elderly people who take multiple medications or have diabetes. It can also affect children and young adults after an illness, due to the temporary suppression of the immune system or antibiotic use.
If you have oral thrush, a doctor will usually prescribe a course of anti-fungal medication for at least a month.
Black coating
Smoking or consuming a lot of strong-coloured food and drink – such as tea and coffee, or dishes with tumeric – can cause a furry appearance. This is known as a black hairy tongue. It’s not hair, but an overgrowth of bacteria which may indicate poor oral hygiene.
Smoking can add to poor oral hygiene and make the tongue look black. Sophon Nawit/Shutterstock Pink patches
Pink patches surrounded by a white border can make your tongue look like a map – this is called “geographic tongue”. It’s not known what causes this condition, which usually doesn’t require treatment.
Pain and inflammation
A red, sore tongue can indicate a range of issues, including:
- nutritional deficiencies such as folic acid or vitamin B12
- diseases including pernicious anaemia, Kawasaki disease and scarlet fever
- inflammation known as glossitis
- injury from hot beverages or food
- ulcers, including cold sores and canker sores
- burning mouth syndrome.
Dryness
Many medications can cause dry mouth, also called xerostomia. These include antidepressants, anti-psychotics, muscle relaxants, pain killers, antihistamines and diuretics. If your mouth is very dry, it may hurt.
What about cancer?
White or red patches on the tongue that can’t be scraped off, are long-standing or growing need to checked out by a dental professional as soon as possible, as do painless ulcers. These are at a higher risk of turning into cancer, compared to other parts of the mouth.
Oral cancers have low survival rates due to delayed detection – and they are on the rise. So checking your tongue for changes in colour, texture, sore spots or ulcers is critical.

The push for Medicare to cover weight-loss drugs: An explainer
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.
The largest U.S. insurer, Medicare, does not cover weight-loss drugs, making it tougher for older people to get access to promising new medications.
If you cover stories about drug costs in the U.S., it’s important to understand why Medicare’s Part D pharmacy program, which covers people aged 65 and older and people with certain disabilities, doesn’t cover weight-loss drugs today. It’s also important to consider what would happen if Medicare did start covering weight loss drugs. This explainer will give you a brief overview of the issues and then summarize some recent publications the benefits and costs of drugs like semaglutide and tirzepatide.
First, what are these new and newsy weight loss drugs?
Semaglutide is a medication used for both the treatment of type 2 diabetes and for long-term weight management in adults with obesity. It debuted in the United States in 2017 as an injectable diabetes drug called Ozempic, manufactured by Novo Nordisk. It’s part of a class of drugs that mimics the action of glucagon, a substance that the human body makes to aid digestion.
Glucagon-like peptide-1 (GLP-1) drugs like semaglutide help prompt the body to release insulin. But they also cause a minor delay in the pace of digestion, helping people feel sated after eating.
That second effect turned Ozempic into a widely used weight-loss drug, even before the Food and Drug Administration (FDA) gave its okay for this use. Doctors in the United States can prescribe medicines for uses beyond those approved by the FDA. This is known as off-label use.
In writing about her own experience in using the medicine to help her shed 40 pounds, Washington Post columnist Ruth Marcus in June noted that Novo Nordisk mentioned the potential for weight loss in its “ubiquitous cable ads (‘Oh-oh-oh, Ozempic!’)”
The American Society of Health-System Pharmacists has reported shortages of semaglutide due to demand, leaving some people with diabetes struggling to find supply of the medicine.
Novo Nordisk won Food and Drug Administration (FDA) approval in 2021 to market semaglutide as an injectable weight loss drug under the name Wegovy, but with a different dosing regimen than Ozempic. Rival Eli Lilly first won FDA approval of its similar GLP-1 diabetes drug, tirzepatide, in the United States in 2022 and sells it under the brand name Mounjaro.
In November of 2023, Eli Lilly won FDA approval to sell tirzepatide as a weight-loss drug, soon-to-be marketed under the brand name Zepbound. The company said it will set a monthly list price for a month’s supply of the drug at $1,059.87, which the company described as 20% discount to the cost of rival Novo Nordisk’s Wegovy. Wegovy has a list price of $1,349.02, according to the Novo Nordisk website.
Even when their insurance plans officially cover costs for weight loss drugs, consumers may face barriers in seeking that coverage for these drugs. Commercial health plans have in place prior authorization requirements to try to limit coverage of new weight-loss shots to those who qualify for these treatments. The Wegovy shot, for example, is intended for people whose weight reaches a certain benchmark for obesity or who are overweight and have a condition related to excess weight, such as diabetes, high blood pressure or high cholesterol.
State Medicaid programs, meanwhile, have taken approaches that vary by state. For example, the most populous U.S. state, California, provides some coverage to new weight-loss injections through its Medicaid program, but many others, including Texas, the No. 2 state in terms of population, do not, according to an online tool that Novo Nordisk created to help people check on coverage.
Medicare does cover semaglutide for treatment of diabetes, and the insurer reported $3 billion in 2021 spending on the drug under Medicare Part D. Congress last year gave Medicare new tools that might help it try to lower the cost of semaglutide.
Medicare is in the midst of implementing new authority it gained through the Inflation Reduction Act (IRA) of 2022 to negotiate with companies about the cost of certain medicines.
This legislation gave Medicare, for the first time, tools to directly negotiate with pharmaceutical companies on the cost of some medicines. Congress tailored this program to spare drug makers from negotiations for the first few years they put new medicines on the market, allowing them to recoup investment in these products.
Why doesn’t Medicare cover weight-loss drugs?
Congress created the Medicare Part D pharmacy program in 2003 to address a gap in coverage that had existed since the creation of Medicare in 1965. The program long covered the costs of drugs administered by doctors and those given in hospitals, but not the kinds of medicines people took on their own, like Wegovy shots.
In 2003, there seemed to be good reasons to leave weight-loss drugs out of the benefit, write Inmaculada Hernandez of the University of California, San Diego, and coauthors in their September 2023 editorial in the Journal of General Internal Medicine, “Medicare Part D Coverage of Anti-obesity Medications: a Call for Forward-Looking Policy Reform.”
When members of Congress worked on the Part D benefit, the drugs available on the market were known to have limited effectiveness and unpleasant side effects. And those members of Congress were aware of how a drug combination called fen-phen, once touted as a weight-loss miracle medicine, turned out in rare cases to cause fatal heart valve damage. In 1997, American Home Products, which later became Wyeth, took its fen-phen product off the market.
But today GLP-1 drugs like semaglutide appear to offer significant benefits, with far less risk and milder side effects, write Hernandez and coauthors.
“Other than budget impact, it is hard to find a reason to justify the historical statutory exclusion of weight loss drugs from coverage other than the stigma of the condition itself,” they write.
What’s happening today that could lead Medicare to start covering weight loss drugs?
Novo Nordisk and Eli Lilly both have hired lobbyists to try to persuade lawmakers to reverse this stance, according to Senate records. Pro tip: You can use the Senate’s lobbying disclosure database to track this and other issues. Type in the name of the company of interest and then read through the forms.
Some members of Congress already have been trying for years to strike the Medicare Part D restriction on weight-loss drugs. Over the past decade, senators Tom Carper (D-DE) and Bill Cassidy, MD, (R-LA) have repeatedly introduced bills that would do that. They introduced the current version, the Treat and Reduce Obesity Act of 2023, in July. It has the support of 10 other Republican senators and seven Democratic ones, as of Dec. 19. The companion House measure has the support of 41 Democrats and 23 Republicans in that chamber, which has 435 seats.
The influential nonprofit Institute for Clinical and Economic Review conducts in-depth analyses of drugs and medical treatments in the United States. ICER last year recommended passage of a law allowing Medicare Part D to cover weight-loss medications. ICER also called for broader coverage of weight-loss medications in state Medicaid programs. Insurers, including Medicare, consider ICER’s analyses in deciding whether to cover treatments.
While offering these calls for broader coverage as part of a broad assessment of obesity management, ICER also urged companies to reduce the costs of weight-loss medicines.
Most people with obesity can’t achieve sustained weight loss through diet and exercise alone, said David Rind, ICER’s chief medical officer in an August 2022 statement. The development of newer obesity treatments represents the achievement of a long-standing goal of medical research, but prices of these new products must be reasonable to allow broad access to them, he noted.
After an extensive process of reviewing studies, engaging in public debate and processing feedback, ICER concluded that semaglutide for weight loss should have an annual cost of $7,500 to $9,800, based on its potential benefits.
What does academic research say about the benefits and the potential costs of new obesity drugs?
Here are a couple of studies to consider when covering the ongoing story of weight-loss drug costs:
Medicare Part D Coverage of Antiobesity Medications — Challenges and Uncertainty Ahead
Khrysta Baig, Stacie B. Dusetzina, David D. Kim and Ashley A. Leech. New England Journal of Medicine, March 2023In this Perspective piece, researchers at Vanderbilt University create a series of estimates about how much Medicare may have to spend annually on weight-loss drugs if the program eventually covers these drugs.
These include a high estimate — $268 billion — based on an extreme calculation, one reflecting the potential cost if virtually all people on Medicare who have obesity used semaglutide. In an announcement of the study on the Vanderbilt website, lead author Khrysta Baig described this as a “purely hypothetical scenario,” but one that “ underscores that at current prices, these medications cannot be the only way – or even the main way – we address obesity as a society.”
In a more conservative estimate, Bhaig and coauthors consider a case where only about 10% of those eligible for obesity treatment opted for semaglutide, which would result in $27 billion in new costs.
(To put these numbers in context, consider that the federal government now spends about $145 billion a year on the entire Part D program.)
It’s likely that all people enrolled in Part D would have to pay higher monthly premiums if Medicare were to cover weight-loss injections, Baig and coauthors write.
Baig and coauthors note that the recent ICER review of weight-loss drugs focused on patients younger than the Medicare population. The balance of benefits and risks associated with weight-loss drugs may be less favorable for older people than the younger ones, making it necessary to study further how these drugs work for people aged 65 and older, they write. For example, research has shown older adults with a high blood sugar level called prediabetes are less likely to develop diabetes than younger adults with this condition.
SELECTing Treatments for Cardiovascular Disease — Obesity in the Spotlight
Amit Khera and Tiffany M. Powell-Wiley. New England Journal of Medicine, Dec. 14, 2023
Semaglutide and Cardiovascular Outcomes in Patients Without Diabetes
A Michael Lincoff, et. al. New England Journal of Medicine, Dec. 14, 2023.An editorial accompanies the publication of a semaglutide study that drew a lot of coverage in the media. The Semaglutide and Cardiovascular Outcomes in Obesity without Diabetes (SELECT) study was a randomized controlled trial, conducted by Novo Nordisk, which looked at rates of cardiovascular events in people who already had known heart risk and were overweight, but not diabetic. Patients were randomly assigned to receive a once-weekly dose of semaglutide (Wegovy) or a placebo.
In the study, the authors report that of the 8,803 patients who took Wegovy in the trial, 569 (6.5%)
The study also reports a mean 9.4% reduction in body weight among patients taking Wegovy, while those on placebo had a mean loss of 0.88%.
The findings suggest Wegovy may be a welcome new treatment option for many people who have coronary disease and are overweight, but are not diabetic, write Khera and Powell-Wiley in their editorial.
But the duo, both of whom focus on disease prevention in their research, also call for more focus on the prevention and root causes of obesity and on the use of proven treatment approaches other than medication.
“Socioeconomic, environmental, and psychosocial factors contribute to incident obesity, and therefore equity-focused obesity prevention and treatment efforts must target multiple levels,” they write. “For instance, public policy targeting built environment features that limit healthy behaviors can be coupled with clinical care interventions that provide for social needs and access to treatments like semaglutide.”

Protein: How Much Do We Need, Really?
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.
Mythbusting Protein!
Yesterday, we asked you for your policy on protein consumption. The distribution of responses was as follows:
- A marginal majority (about 55%) voted for “Protein is very important, but we can eat too much of it”
- A large minority (about 35%) voted for “We need lots of protein; the more, the better!”
- A handful (about 4%) voted for “We should go as light on protein as possible”
- A handful (6%) voted for “If we don’t eat protein, our body will create it from other foods”
So, what does the science say?
If we don’t eat protein, our body will create it from other foods: True or False?
Contingently True on an absurd technicality, but for all practical purposes False.
Our body requires 20 amino acids (the building blocks of protein), 9 of which it can’t synthesize and absolutely must get from food. Normally, we get those amino acids from protein in our diet, and we can also supplement them by buying amino acid supplements.
Specifically, we require (per kg of bodyweight) a daily average of:
- Histidine: 10 mg
- Isoleucine: 20 mg
- Leucine: 39 mg
- Lysine: 30 mg
- Methionine: 10.4 mg
- Phenylalanine*: 25 mg
- Threonine: 15 mg
- Tryptophan: 4 mg
- Valine: 26 mg
*combined with the non-essential amino acid tyrosine
Source: Protein and Amino Acid Requirements In Human Nutrition: WHO Technical Report
However, to get the requisite amino acid amounts, without consuming actual protein, would require gargantuan amounts of supplementation (bearing in mind bioavailability will never be 100%, so you’ll always need to take more than it seems), using supplements that will have been made by breaking down proteins anyway.
So unless you live in a laboratory and have access to endless amounts of all of the required amino acids (you can’t miss even one; you will die), and are willing to do that for the sake of proving a point, then you do really need to eat protein.
Your body cannot, for example, simply break down sugar and use it to make the protein you need.
On another technical note… Do bear in mind that many foods that we don’t necessarily think of as being sources of protein, are sources of protein.
Grains and grain products, for example, all contain protein; we just don’t think of them as that because their macronutritional profile is heavily weighted towards carbohydrates.
For that matter, even celery contains protein. How much, you may ask? Almost none! But if something has DNA, it has protein. Which means all plants and animals (at least in their unrefined forms).
So again, to even try to live without protein would very much require living in a laboratory.
We can eat too much protein: True or False?
True. First on an easy technicality; anything in excess is toxic. Even water, or oxygen. But also, in practical terms, there is such a thing as too much protein. The bar is quite high, though:
❝Based on short-term nitrogen balance studies, the Recommended Dietary Allowance of protein for a healthy adult with minimal physical activity is currently 0.8 g protein per kg bodyweight per day❞
❝To meet the functional needs such as promoting skeletal-muscle protein accretion and physical strength, dietary intake of 1.0, 1.3, and 1.6 g protein per kg bodyweight per day is recommended for individuals with minimal, moderate, and intense physical activity, respectively❞
❝Long-term consumption of protein at 2 g per kg bodyweight per day is safe for healthy adults, and the tolerable upper limit is 3.5 g per kg bodyweight per day for well-adapted subjects❞
❝Chronic high protein intake (>2 g per kg bodyweight per day for adults) may result in digestive, renal, and vascular abnormalities and should be avoided❞
Source: Dietary protein intake and human health
To put this into perspective, if you weigh about 160lbs (about 72kg), this would mean eating more than 144g protein per day, which grabbing a calculator means about 560g of lean beef, or 20oz, or 1¼lb.
If you’re eating quarter-pounder burgers though, that’s not usually so lean, so you’d need to eat more than nine quarter-pounder burgers per day to get too much protein.
High protein intake damages the kidneys: True or False?
True if you have kidney damage already; False if you are healthy. See for example:
- Effects of dietary protein restriction on the progression of advanced renal disease in the modification of diet in renal disease study
- A high protein diet has no harmful effects: a one-year crossover study in healthy male athletes
High protein intake increases cancer risk: True or False?
True or False depending on the source of the protein, so functionally false:
- Eating protein from red meat sources has been associated with higher risk for many cancers
- Eating protein from other sources has been associated with lower risk for many cancers
Source: Red Meat Consumption and Mortality Results From 2 Prospective Cohort Studies
High protein intake increase risk of heart disease: True or False?
True or False depending on the source of the protein, so, functionally false:
- Eating protein from red meat sources has been associated with higher risk of heart disease
- Eating protein from other sources has been associated with lower risk of heart disease

In summary…
Getting a good amount of good quality protein is important to health.
One can get too much, but one would have to go to extremes to do so.
The source of protein matters:
- Red meat is associated with many health risks, but that’s not necessarily the protein’s fault.
- Getting plenty of protein from (ideally: unprocessed) sources such as poultry, fish, and/or plants, is critical to good health.
- Consuming “whole proteins” (that contain all 9 amino acids that we can’t synthesize) are best.
