Is Chicken Really a Health Food?

Chicken has become the default protein of healthy eating. But from what the bird eats to what happens at the processing plant—and eventually on your grill—the story is more complicated than “lean protein equals healthy food.”

When I was a kid, there was a guy named Charlie who worked at the marina.

I don't remember everything about him, but I remember what he looked like.

He was one of the leanest human beings I had ever seen. This guy had veins on top of veins.

Every time I saw him, he seemed to be doing something physical—raking gravel, moving things, working around the boats, spending his days outside in the sun. As a kid who was already interested in muscles, you notice somebody like that.

Years later, I happened to see Charlie again. I told him I remembered him from when I was a kid and remembered how unbelievably lean he had been.

Somewhere in that conversation he told me something else I remembered:

He used to eat a lot of boiled chicken.

Boiled chicken?

Who boils chicken?

Apparently Charlie did.

Looking back, maybe it wasn't such a crazy idea.

Chicken—particularly skinless chicken breast—is almost perfectly designed for somebody trying to get lean. It provides a tremendous amount of high-quality protein without bringing many calories along for the ride. Boiling or poaching it doesn't require adding frying fat. Charlie was also doing physical work all day.

High protein. High energy expenditure. Relatively little caloric baggage attached to the protein.

You don't need a complicated nutritional theory to understand why that combination might coexist with a very lean man.

But there's another question I never thought about when I was looking at Charlie as a kid:

Was it healthy?

That's a different question.

And the more I looked into chicken, the more interesting that question became.

Chicken Earned Its Reputation

Let's give chicken its due.

Chicken breast really is an extraordinary protein food. It provides complete, high-quality protein while remaining relatively lean. It's also useful for nutrients including niacin, vitamin B6, selenium and phosphorus.

Then there's another advantage that doesn't get enough attention:

Chicken is relatively inexpensive.

Prices obviously change by cut, store and year, but chicken has historically offered an unusually practical combination of affordability, availability and high-quality animal protein.[1]

That's part of why it became bodybuilding food.

It's part of why it became diet food.

And it's part of why somebody can meal-prep a week's worth of chicken without taking out a second mortgage.

So chicken's reputation wasn't invented.

But somewhere along the way, excellent protein source became almost interchangeable with nutritionally ideal food.

Those aren't necessarily the same thing.

And before we even get to nutrition, it's worth asking:

What exactly is a modern chicken?

This Isn't Your Grandparents' Chicken

The modern broiler is an extraordinary example of selective breeding.

Researchers have maintained chicken strains representing earlier eras, allowing scientists to compare older genetics with modern broilers under similar conditions.

One remarkable experiment compared broilers representing 1957, 1978 and 2005 genetics.

From 1957 to 2005, growth increased by more than 400 percent, while feed required relative to growth fell dramatically. The potential yield of the major breast muscle increased by 79 percent in males and 85 percent in females.

Interestingly, the experiment didn't support the simplistic idea that selection merely made modern chickens enormously fatter. Abdominal fat actually decreased with selection.[2]

Humans didn't merely become better at raising chickens.

We substantially changed the chicken.

That raises the obvious question.

Are They Pumping These Birds Full of Hormones?

No.

Hormones aren't approved for raising chickens in the United States.[3]

In fact, this creates one of my favorite pieces of chicken-label marketing.

If your package proudly says:

“No Hormones Added”

you aren't necessarily buying anything special.

USDA says such a claim on poultry must be accompanied by language explaining that federal regulations prohibit the use of hormones.[3]

So don't pay extra for chicken simply because somebody put “no hormones” in big letters on the package.

The enormous modern chicken breast isn't evidence of hormone injections.

It's evidence of what decades of genetics, nutrition and agricultural selection can accomplish.

Chickens Aren't Vegetarians

There's another useful distinction when we start talking about what chickens eat.

Chickens are omnivores.

Given the opportunity to forage, they'll consume plant material and seeds but also insects, worms and other animal matter.[4]

Commercial broilers obviously aren't roaming around all day assembling their own menu. They're generally eating carefully formulated rations designed to provide energy, protein, amino acids, vitamins and minerals while supporting health and extremely efficient growth.

Grains—particularly corn in the United States—and protein sources such as soybean meal are common ingredients.[4]

That isn't automatically bad.

But it matters because:

What the chicken eats can influence what eventually ends up in the chicken.

This becomes particularly obvious when we look at fat.

You Are, Indirectly, Eating What the Chicken Ate

Researchers can deliberately alter the fatty-acid composition of chicken meat by altering the bird's diet.

Supplementing poultry feed with omega-3 sources such as flaxseed, fish oil or algae can increase omega-3 fatty acids deposited in the bird's tissues.[5]

That's essentially a demonstration of a larger principle:

Chicken meat isn't nutritionally immutable.

Its fatty-acid composition responds to what the animal eats.

That brings us to one of the more recent criticisms of chicken:

It's loaded with omega-6 fat.

There's something worth discussing there, but context matters enormously.

Chicken breast, thighs, wings and skin aren't nutritionally interchangeable.

Skinless breast contains relatively little total fat. Even if you don't particularly like its omega-6-to-omega-3 ratio, there simply isn't much fat there.

Eat thighs, wings and especially skin and the calculation changes.

So if we're discussing omega-6, don't merely ask:

What's the ratio?

Also ask:

How much total fat am I actually eating?

Dose matters.

What About Arsenic?

Here's one of the stranger chicken stories.

You may have heard that chickens were given arsenic.

It sounds like one of those food scares that circulates online until somebody investigates it.

Except this one was real.

Arsenic-containing animal drugs were historically used in poultry production. The best known was roxarsone, sold as 3-Nitro.

Roxarsone contained organic arsenic, which raised less toxicological concern than inorganic arsenic.

Then FDA scientists developed analytical methods capable of measuring very low concentrations of inorganic arsenic in chicken tissue.

They found that chickens treated with roxarsone had higher concentrations of inorganic arsenic in their livers than untreated chickens.[6]

Sales were suspended, and FDA subsequently withdrew the approvals for roxarsone. The last arsenic-based animal drug then marketed in the United States, nitarsone, was discontinued in 2015.[6]

So the arsenic story gets an unusual verdict:

The rumor was substantially true.

But it's largely a historical argument against U.S.-raised chicken today.

The international phaseout didn't occur everywhere simultaneously, which makes imported poultry a reasonable question to ask. But a reasonable question shouldn't be turned into an accusation.

I haven't found adequate current evidence demonstrating that chicken entering the United States today is being raised with roxarsone.

That's an important distinction throughout this subject:

Something being historically true doesn't make it currently true.

Do Chickens Eat Their Own Poop?

Here's another rumor.

Technically?

Sometimes.

Chickens peck and forage. Birds living on litter encounter bedding, feathers, spilled feed and fecal material, so incidental ingestion can occur.

But that's quite different from saying:

“Commercial chickens are routinely fed their own poop.”

Modern commercial feeds are formulated to provide energy, protein, amino acids, vitamins and minerals.[4]

The better question isn't whether a chicken has ever pecked at something disgusting.

It's what commercial chickens are routinely fed and whether that feed meaningfully changes the safety or nutritional composition of the meat.

As we've already seen with fatty acids, sometimes it does.

What About Antibiotics?

Antibiotics belong in this discussion, but once again the popular concern and the scientifically important concern aren't quite the same thing.

People sometimes imagine that conventionally raised chicken arrives at the supermarket full of antibiotics.

That's not how the regulatory system is supposed to work.

When antibiotics are used, withdrawal periods can be required before slaughter so residues fall within established tolerances. USDA's Food Safety and Inspection Service also samples poultry for residues and reports that violations have represented a very low percentage of samples.[7]

So there are actually two different questions:

Are illegal antibiotic residues left in the chicken I'm eating?

and:

Can antibiotic use in animal agriculture contribute to antimicrobial resistance?

The second is the larger public-health concern.

Using antimicrobial drugs creates selective pressure that can favor resistant bacteria. Resistant organisms and resistance genes can move among animals, humans, food and the environment. That's why FDA, USDA and CDC monitor antimicrobial resistance in foodborne bacteria.

This also makes “raised without antibiotics” different from “no hormones.”

USDA permits “no antibiotics added” claims when producers provide documentation demonstrating that the animals were raised without antibiotics.[3]

So the claim actually describes a different production practice.

But don't confuse that with:

“Ordinary chicken contains unsafe amounts of antibiotics.”

Those are different claims.

The stronger public-health argument for prudent antibiotic use in agriculture is the ecological problem of antimicrobial resistance, not the idea that you're receiving a pharmaceutical dose with dinner.

Wait—Don't They Wash Chicken in Chlorine?

Now we reach one of the most alarming-sounding parts of chicken processing.

Yes, chlorine-based antimicrobial interventions can be used in poultry processing.

But chlorine isn't the entire story, and it's important not to collapse every antimicrobial into “chlorine.”

Modern processors can use several interventions. USDA's list includes systems based on peroxyacetic acid (PAA) along with hydrogen peroxide and acetic acid. Depending on the particular approved poultry application, PAA concentrations can reach 2,000 parts per million.[8]

Let's be very clear:

That's PAA—not 2,000 ppm chlorine.

Different antimicrobial systems have different approved concentrations and applications.

And even the 2,000 ppm number can sound terrifying if presented badly:

YOUR CHICKEN CAN BE WASHED IN 2,000 PPM CHEMICALS.

But that's lousy toxicology.

The concentration of a chemical in processing water isn't the same thing as the amount remaining in the chicken when you eat it.

Processing concentration isn't dietary dose.

Swimming pools provide a useful conceptual analogy because most of us are familiar with exposure to chlorinated water. But swimming-pool chlorine and poultry-processing antimicrobials aren't equivalent exposures, so the analogy should stop there.

The meaningful questions are:

Which chemical was used?

At what concentration?

How was it applied?

How much remains?

What reaction products are produced?

How much reaches the consumer?

And at that dose, is there evidence of harm?

Simply discovering that a chemical touched your food doesn't answer those questions.

And there's another part of this story that rarely receives equal attention.

There's a Reason They Treat Raw Chicken

Raw chicken can be microbiologically nasty.

CDC says raw chicken can carry organisms including Salmonella, Campylobacter and Clostridium perfringens.

CDC estimates that approximately 1 million people in the United States become sick each year from contaminated poultry and reports that roughly 1 in 25 packages of chicken at grocery stores is contaminated with Salmonella.[9]

Suddenly antimicrobial processing looks a little different.

The comparison isn't:

chemically treated chicken versus perfectly pristine untreated chicken.

It's:

the risks and benefits of antimicrobial intervention versus a genuine microbial problem.

That doesn't prove every intervention is ideal.

It simply means the treatment and the problem it's intended to solve need to be evaluated together.

Incidentally, this also explains why washing raw chicken in your kitchen isn't a particularly clever solution. CDC says raw chicken is ready to cook and doesn't need to be washed; splashing can instead spread bacteria around the kitchen.[9]

And after worrying about everything that happened to the chicken before we bought it, we may substantially change its chemistry ourselves during the final few minutes before dinner.

Maybe What You Do to the Chicken Matters More

Think about the classic fitness meal:

A heavily grilled chicken breast.

Nice grill marks.

Dark brown.

Maybe a little black around the edges.

Looks healthy.

But high-temperature cooking of muscle meat can produce heterocyclic amines, or HCAs.

Cooking over an open flame can additionally expose meat to polycyclic aromatic hydrocarbons, or PAHs, as fat and juices hit hot surfaces or flames and smoke deposits compounds back onto the meat.

The National Cancer Institute explains that high-temperature cooking methods such as pan frying and grilling can form HCAs, while direct-flame grilling and smoking can contribute PAHs. Longer cooking and higher temperatures generally increase HCA formation.[10]

That doesn't mean eating a grilled chicken breast causes cancer.

Human outcome data are considerably more complicated than that.[10]

But cooking method unquestionably changes the chemistry of the food.

And now Charlie's boiled chicken doesn't sound quite as ridiculous.

Boiling, simmering and poaching allow chicken to reach a safe internal temperature without creating the extreme surface temperatures involved in heavy grilling or blackening.

Charlie may have stumbled onto one of the least glamorous cooking methods imaginable—but one that also avoids a lot of high-temperature browning.

How Hot Does Chicken Actually Need to Get?

USDA recommends cooking poultry to a safe minimum internal temperature of 165°F (73.9°C) as measured with a food thermometer.[7]

That doesn't mean chicken becomes progressively safer or healthier because you continue cooking it until it's 190°F and resembles a roofing shingle.

There is a difference between:

properly cooked

and

obliterated.

A thermometer can tell you when you've accomplished the first without relying on the second.

Before You Throw Away the Marinade…

Here's an interesting twist.

You might assume that adding herbs, spices and other ingredients before exposing chicken to high heat simply creates more opportunities for undesirable cooking chemistry.

Individual marinade ingredients certainly undergo chemical changes during heating.

But many marinades—particularly those containing antioxidant-rich herbs and spices—may actually reduce lipid oxidation and inhibit formation of some HCAs and PAHs.

Research reviews have reported protective effects from a variety of natural marinade ingredients, although results depend upon the ingredients, concentration, cooking method and cooking time.[11,12]

So the practical lesson isn't:

Don't marinate chicken because the marinade oxidizes.

It may actually be closer to:

A thoughtfully formulated marinade may protect the meat from some of the chemistry you're about to create on the grill.

Fried Chicken Is a Different Animal

Not literally.

Nutritionally.

Start with skinless chicken breast and you have an unusually efficient protein source.

Bread it, submerge it in oil and fry it and you've changed the equation.

Water leaves.

Oil enters.

Breading contributes additional calories.

High-temperature browning occurs.

And the frying oil itself begins changing.

During frying, oils undergo oxidation, hydrolysis and polymerization, producing numerous degradation products. The amount and type of degradation depend upon the oil, temperature, time, oxygen exposure, food being fried and whether the oil is repeatedly reused.[13,14]

And that last point matters.

Frying Once Isn't the Same Thing as Frying All Day

Suppose you put fresh olive oil into a pan at home, cook some chicken and eat dinner.

Now compare that with oil maintained in a commercial fryer for hours while batch after batch of food passes through it.

Those aren't chemically equivalent exposures.

Repeated heating contributes to progressive oil degradation. Oxidation products, aldehydes, free fatty acids, polymers and other compounds can accumulate as frying continues.[13,14]

So:

Chicken cooked once in fresh olive oil isn't the same chemical proposition as chicken emerging from heavily reused fryer oil.

That distinction tends to disappear when everything gets lumped together as “fried food.”

What About Trans Fats?

Trans fats deserve a mention here, but the story has changed considerably.

The notorious artificial trans fats of the past largely came from partially hydrogenated oils. In 2015, FDA determined that partially hydrogenated oils were no longer “generally recognized as safe,” which ultimately removed their ordinary approved uses from the U.S. food supply.[15]

But can frying itself create trans fat?

Yes—but under ordinary frying conditions, apparently not very much.

A systematic review and meta-analysis covering 33 studies and 21 cooking oils found that heating oils below 200°C (392°F) had little overall effect on trans-fat concentrations.

Above 200°C, trans-fat formation increased with temperature, and prolonged heating at those higher temperatures increased it further. Even then, the magnitude was small compared with the trans-fat concentrations historically found in partially hydrogenated oils.[16]

That puts ordinary frying into perspective.

Frying a piece of chicken once in fresh oil isn't suddenly converting that oil into the trans-fat-laden shortening of decades past.

But it reinforces a theme we've already encountered:

Temperature, time and repeated use matter.

What Should You Fry It In?

This question gets tribal very quickly.

Seed oils versus animal fats.

Butter versus olive oil.

Coconut oil versus everything.

The chemistry is more interesting than the slogans.

Polyunsaturated fatty acids contain more double bonds and are generally more susceptible to oxidation than monounsaturated or saturated fatty acids.

That gives highly saturated fats such as coconut oil, ghee, lard or tallow a legitimate stability advantage under some high-temperature conditions. High-oleic oils can also offer useful thermal stability because they're rich in monounsaturated rather than highly polyunsaturated fat.

But oxidative stability isn't the only health question.

A fat can resist oxidation beautifully while also supplying a substantial amount of saturated fat.

So there are really two questions:

What happens to this fat while I heat it?

and:

What happens when this fat becomes a regular part of my diet?

Those questions don't necessarily produce the same winner.

The simplest answer may be the least exciting:

Use appropriate fresh cooking fats, avoid repeatedly abusing them at high temperatures, and don't make deep-fried chicken your primary source of chicken.

Are You Buying Chicken—or Chicken Plus Water and Salt?

Here's a considerably less exotic issue than arsenic or frying chemistry, but it's one you can actually encounter at the grocery store.

Not every package containing what appears to be raw chicken contains exactly the same thing.

Some poultry retains water during processing.

Other chicken products have solutions deliberately added through marinating, tumbling or injection.

Those aren't quite the same thing.

USDA requires retained water to be disclosed when applicable. Poultry products may also contain added solutions made from ingredients such as water, broth, salt, spices or other approved substances, which must be reflected in the labeling.[3]

Now the nutritional profile can change.

In particular:

sodium can go up.

So two chicken breasts that look virtually identical don't necessarily contain identical nutrition.

One may essentially be chicken.

Another may be chicken plus water, salt and other ingredients.

That's not inherently dangerous, and some people may prefer the juicier product.

But if you're buying chicken because you want a simple lean protein—or you're watching sodium—turn the package over and read it.

Complete Protein Doesn't Mean Complete Nutrition

And this brings us back to Charlie.

Suppose he really was eating enormous amounts of boiled chicken.

Was he getting excellent protein?

Absolutely.

Was chicken providing everything he needed nutritionally?

No.

But let's be precise about why.

Chicken is a complete protein, meaning it supplies all of the essential amino acids.

That does not make chicken a nutritionally complete food.

Chicken breast is particularly useful for protein, niacin, vitamin B6, selenium and phosphorus.

Other animal foods have different nutritional strengths.

Lean beef can contribute substantially more heme iron, zinc and vitamin B12, along with compounds such as creatine.

Fatty fish such as salmon provide EPA and DHA omega-3 fatty acids and vitamin D.

Pork is particularly notable for thiamine.

Eggs provide substantial choline and a different collection of micronutrients concentrated largely in the yolk.

Dairy can provide large amounts of calcium and useful amounts of iodine and B12.

Different shellfish can be unusually rich in zinc, copper, selenium, iodine or B12.

So eating more and more chicken doesn't necessarily make a high-protein diet progressively more nutritious.

Eventually you're mostly getting:

more of chicken's nutritional fingerprint.

That's where rotating protein sources starts making sense.

Not because the body knows it's Tuesday and demands salmon.

But because:

One food's nutritional peak can fill another food's valley.

Chicken can remain the inexpensive workhorse protein while beef, fish, eggs, dairy, pork and seafood broaden the nutritional landscape.

What About Fiber?

It's common to say meat is “nutritionally incomplete” because it doesn't contain fiber.

Technically, that's not the right argument.

Dietary fiber isn't classified as an essential nutrient in the same sense as an essential amino acid, vitamin or essential fatty acid, although dietary reference values exist because fiber has important physiological and health effects.[17]

So chicken containing no fiber doesn't, by itself, prove that chicken is nutritionally incomplete in the strict essential-nutrient sense.

The better question is:

Could chicken by itself provide all essential nutrients in appropriate quantities without leaving meaningful nutritional gaps or forcing excessive intake of something else?

That's the more scientifically useful standard.

And under that standard, chicken breast shouldn't be mistaken for an entire diet.

Maybe Chicken Isn't the Whole Problem. Maybe It's the Part We Eat.

There's another wrinkle.

When Americans say “chicken,” we usually mean skeletal muscle.

Breast.

Thigh.

Wing.

But that's not the entire animal.

Chicken liver, heart and gizzard have very different nutritional profiles from breast meat. Liver, in particular, is extraordinarily concentrated in nutrients including vitamin A, B12, folate, riboflavin, iron and copper.

This isn't unique to chickens.

Beef liver.

Chicken liver.

Pork liver.

Lamb liver.

Heart.

Kidney.

Different tissues perform different biological jobs, so it shouldn't surprise us that their nutritional compositions differ.

Historically and across many cultures, eating an animal didn't necessarily mean eating only its preferred skeletal muscles.

Modern American meat consumption has narrowed that considerably.

We've essentially reduced the chicken to a few favored pieces.

That raises an interesting question:

Is chicken nutritionally narrow—or have we made eating chicken nutritionally narrow by eating mostly its muscle?

That doesn't mean everyone needs to start eating chicken liver every morning.

Organ meats are so nutrient-dense that more isn't automatically better. Large and frequent liver consumption, for example, can produce very high intakes of preformed vitamin A and other micronutrients.

But organ meats reinforce the broader point:

There isn't one perfect animal food.

Different animals—and different parts of those animals—bring different nutritional packages.

What Do All Those Chicken Labels Actually Mean?

After all of this, standing in front of the poultry case can become surprisingly confusing.

So let's make a few labels less mysterious.

“No Hormones Added”

By itself, this isn't a reason to pay more.

Hormones aren't permitted in raising poultry in the United States.[3]

“Raised Without Antibiotics”

This one does describe a different production practice.

USDA requires supporting documentation for such a claim.[3]

That doesn't mean conventional chicken is supposed to contain unsafe antibiotic residues. As we've already seen, residues and antimicrobial resistance are different issues.

“Organic”

Organic is primarily a production standard.

It tells you about how the bird was raised and what production requirements were followed.

Don't automatically translate it into:

more protein
more vitamins
more minerals

Those would require separate nutritional evidence.

“Free Range”

Again, this primarily describes something about the animal's raising conditions.

It shouldn't automatically be translated into nutritionally superior chicken.

“Natural”

This may mean considerably less than consumers imagine.

In USDA meat and poultry labeling, “natural” generally means that the product contains no artificial ingredients or added color and is only minimally processed.[3]

It doesn't automatically mean:

organic
pasture raised
antibiotic free
or nutritionally superior.

Air Chilled

Air chilling can reduce the amount of water picked up during conventional water chilling.

That may matter for texture, flavor and how much of what you're paying for is chicken versus retained water.

It doesn't automatically make the meat nutritionally superior.

So What Chicken Should I Actually Buy?

After hormones, arsenic, feed, antibiotics, antimicrobial processing, cooking chemistry, frying oils and nutritional completeness, the answer turns out to be surprisingly ordinary.

Start with what you're trying to accomplish.

If your goal is maximum protein for relatively few calories, skinless breast remains extraordinarily efficient.

If you prefer thighs, eat thighs—but understand that they're bringing more fat and a somewhat different nutritional profile.

If you eat the skin, that's another change again.

Then read the package.

If it says:

“contains up to X% solution”

look at what that solution contains.

Check the sodium if that's important to you.

If production practices matter to you, organic or raised-without-antibiotics claims may be worth paying for according to your priorities.

If the package screams “NO HORMONES!”, remember that the chicken next to it wasn't legally supposed to receive hormones either.

And don't automatically assume that the most expensive chicken has the best nutritional profile.

A premium price may reflect farming practices, animal welfare, certification, breed, processing, flavor or texture.

Those things may matter.

They're simply not the same claim as:

“This chicken is nutritionally superior.”

So, Is Chicken Really a Health Food?

After trying fairly hard to find reasons not to like chicken, it survives the investigation surprisingly well.

Hormones?

Not permitted in U.S. poultry. “No hormones added” is therefore less of a premium feature than a marketing statement about something already prohibited.

Arsenic?

A legitimate and disturbing historical issue. FDA actually found increased inorganic arsenic in chickens treated with roxarsone. But those arsenical poultry drugs were subsequently removed from the U.S. market.

Antibiotics?

Illegal residues and antimicrobial resistance aren't the same issue. The more compelling modern concern is responsible antibiotic use and resistance, not the idea that every conventional chicken breast contains a pharmacological dose of antibiotics.

Chlorine and antimicrobial processing?

Real—but don't confuse chlorine with PAA, and don't confuse processing concentration with dietary dose. These interventions also need to be considered alongside the genuine pathogen problem they're intended to control.

Omega-6?

Worth understanding, particularly if you're eating lots of chicken skin and fattier cuts. It's a much less convincing indictment of very lean skinless breast.

Modern breeding?

It has transformed the chicken dramatically. Growth increased by more than 400 percent across the genetic comparison we examined while breast yield and feed efficiency increased enormously.

That's remarkable.

But remarkable isn't synonymous with harmful.

Cooking?

Here we have something we control.

Cook chicken safely.

USDA says 165°F internally.

But don't assume blackening it around the edges makes it healthier.

A marinade containing herbs and spices may actually help limit some undesirable cooking chemistry.

And don't assume a chicken breast cooked once in fresh olive oil is chemically equivalent to fried chicken emerging from repeatedly heated fryer oil.

Nutrition?

Chicken breast is an exceptional protein food.

It isn't an entire diet.

Which brings me back to Charlie.

Maybe Charlie really was onto something.

A physically active guy working outside all day and eating a lot of boiled chicken had constructed a pretty formidable environment for staying lean without ever needing to know what a macro was.

Lots of protein.

Relatively little added fat.

Lots of physical work.

And apparently very little body fat.

But the thing I noticed about Charlie as a kid was that he was incredibly lean.

I had no idea whether he was incredibly well nourished.

Those aren't the same thing.

Chicken may be one of the most practical lean-protein foods available to us. It's relatively inexpensive, versatile, high in protein and—particularly when we're talking about skinless breast—remarkably efficient in terms of protein per calorie.

So eat chicken.

Just understand what you're eating.

Don't pay extra because somebody tells you their chicken wasn't given hormones that aren't permitted anyway.

Don't turn a historical arsenic problem into a claim about every chicken being sold today.

Don't assume the word “chemical” establishes a toxic dose.

Don't confuse a fresh pan of olive oil with an abused restaurant fryer.

Don't burn the hell out of your chicken because you're afraid it isn't cooked.

Rotate your protein sources occasionally instead of asking chicken to provide nutrients it doesn't provide particularly well.

And perhaps most importantly:

Don't ask one chicken breast to do the nutritional work of an entire diet.
