11 Health Benefits of Eating Beef

Last Updated on

Picture of a Beef Steak With Asparagus.A generation or two ago, our parents and grandparents viewed beef as a nutritious health food.

But now?

These days it’s much different, and opinion is split between whether beef is healthful or harms our health.

Some of the more extreme vegan views even call for the authorities to remove meat from the food supply.

Whatever our opinion on red meat might be, there are still some important health benefits of eating beef.

This article takes a close look at 11 of them.

1. Beef Provides a Large Source of L-Carnitine

L-carnitine is a health-promoting compound that occurs naturally in meat products.

In the table below, we can see the L-carnitine content of beef compared to some other animal foods and plant foods (1);

L Carnitine Food Source Amount of L-Carnitine (mg)
Asparagus (1/2 cup) 0.1
Beef (4oz)  56 – 162
 Cheese  2
Chicken Breast (4oz)  3 – 5
Cod (4oz)  4 – 7
 Ice-Cream (1/2 cup) 3
Whole Milk (1 cup) 8
Whole Wheat Bread (1 slice) 0.2

Why is L-Carnitine Important?

Among other functions, L-carnitine plays a part in fat metabolism.

As part of this, L-Carnitine does the job of transporting fats into our mitochondria for burning.

It’s important to clarify that our body can synthesize sufficient amounts of L-carnitine for general needs, and we don’t necessarily need an external intake.

The body synthesizes L-Carnitine within the liver and the process relies on the amino acids L-lysine and L-methionine (2).

As a result, deficiencies are rare.

However, research suggests that a higher dietary intake of L-Carnitine may have some positive health impacts.

Various studies show the following findings;

Heart Health

A meta-analysis of randomized trials suggests that L-carnitine improves patient outcomes. Specifically, it exerts an effect on hypertension, oxidative stress, nitric oxide, and inflammation (3).

A further systematic review found that L-carnitine is associated with a 27% reduction in all-cause mortality in heart failure patients (4).


A systematic review shows that higher L-carnitine intake in type 2 diabetes patients improves fasting glucose levels and the overall cholesterol profile (5).

Weight Loss

According to a systematic review and meta-analysis of nine randomized controlled trials, subjects using L-carnitine supplementation lost “significantly more weight” than the control group (6).

It’s worth noting that while there are many L-carnitine supplements around, the absorption rate is poor in comparison to beef.

In fact, our body only absorbs around 14-18% of the synthetic form of the nutrient (7).

Key Point: L-carnitine is a compound that naturally occurs in beef. It has a positive impact on various health markers.

2. Beef Provides the “Master Antioxidant” Glutathione

Commonly known as the ‘master antioxidant,’ glutathione has a score of research linking it to (8);

  • Anti-aging benefits
  • Increasing longevity
  • Preventing illness
  • Reducing the risk of chronic disease
  • Strengthening the immune system

It helps protect every cell in our body from cellular damage, which can lead to many chronic diseases.

On the other hand, a deficiency in glutathione contributes to oxidative stress and inflammation (9).

As a result, keeping glutathione levels high is important for our overall health.

Subsequently, the question becomes “how can we keep our glutathione levels high?”

Endogenous Glutathione Production and Dietary Sources

First of all, our body produces glutathione endogenously.

In other words, our body uses raw materials (in this case: amino acids) to make glutathione.

For this process to occur, we should have adequate levels of the amino acids cysteine, glutamate, and glycine (10).

These amino acids are known as glutathione precursors, and each of these amino acids is present in beef.

On the positive side, beef also contains a reasonably high source of complete (pre-formed) dietary glutathione.

Key Point: Keeping our glutathione levels high is critical for good health, and beef is a food that helps us to achieve this. Glutathione detoxes our body better than any ‘detox plan’ or supplement can.

3. Beef is High in Protein

A Strong Young Woman Pushing Tires Over.There are numerous reasons why we should strive to ensure a sufficient protein intake and these include;

  • Protein is the building block our body uses to repair and make bone, skin, and cartilage.
  • Sufficient protein helps us to build and maintain lean muscle mass.
  • Out of all macronutrients, protein is the most satiating, and it discourages food cravings.

Beef is packed with health-promoting amino acids, and it’s one of the single biggest sources of protein in the human diet.

For instance, a 6oz (170g) portion of 80% lean beef provides 46g protein.

Should we opt for a leaner variety of beef, the protein content can be even higher. (11).

The Importance of Lean Mass

As we age, building—or at least holding on to—lean mass should be a priority.

Research shows that older adults with lower muscle mass are at a higher risk of mortality.

Speaking bluntly, the more skeletal muscle mass someone loses as they age, the higher their risk of an earlier death (12).

Also, the rate of muscle protein synthesis rapidly drops as we age, making it a lot harder to build and maintain muscle (13).

Considering this, we should ensure we’re eating a sufficient amount of protein – this is especially essential for elderly people.

On this note, beef is one of the best protein-rich foods out there.

Key Point: Protein is essential for optimal health, and especially so as we age. Beef provides an abundant amount of this macronutrient.

4. Beef is Rich in Minerals

If you’re looking to increase your intake of various minerals, then beef is one of the best options to consider.

First of all, beef is relatively nutrient-dense in minerals.

Here we can see the mineral content of 80% lean beef (11);

 Mineral NameAmount per 6oz portion (% DV)

As shown in the table, beef provides more than half of the day’s recommended amount of selenium and zinc.

Many people have deficiency issues with some of these minerals.

So, the nutritional value of beef can help fight prevalent global deficiencies in iron, magnesium, and zinc (14, 15, 16).

Key Point: Beef is rich in several essential minerals—especially iron, phosphorus, selenium, and zinc.

5. Eating Beef Helps TO Prevent Iron Deficiency Anemia

Diagram Showing How Iron Deficiency Anemia Works.

We touched on mineral deficiencies in the last point, but iron deficiency anemia deserves a mention of its own.

Sadly, iron deficiency anemia is a growing epidemic around the world.

In a developed country such as the United States, nutrient deficiencies shouldn’t be a cause of death, yet anemia kills thousands every year.

To be exact, the latest release of statistics showed that Anemia hospitalized 146,000 Americans in one year. 5,219 of these people died (17).

Globally it’s even worse, and according to the World Health Organization, 1.62 billion people suffer from iron deficiency anemia (18).

Heme and Non-Heme Iron

There are two types of iron available in food, and we refer to them as heme and non-heme iron.

  • Heme Iron: Heme iron is the most bioavailable form of iron, and meat and other animal foods exclusively contain it.
  • Non-Heme Iron: Non-heme iron is found in plant foods such as fruit, vegetables, and nuts. In comparison to heme iron, our body finds it more difficult to absorb.

One of the best health benefits of beef meat is that it contains a substantial amount of heme iron.

The best source of all? Beef liver.

Interestingly, anemia disproportionately affects females. Perhaps this isn’t a huge surprise when we think about how society seems to shame women who eat meat.

The imagery of women smiling while eating a bowl of salad is quite ubiquitous.

Key Point: Eat more beef to help prevent iron deficiency anemia.

6. Beef Contains Carnosine

The Molecular Structure of the Amino Acid Carnosine,

Another advantage of eating beef is that it provides an abundance of carnosine.

Carnosine (beta-analyl-L-histidine) is a compound created by the combination of the amino acids alanine and histidine. It is found throughout the body, and it has several important roles in human health.

As beef is one of the highest sources of carnosine (containing about 50% more than poultry), this is another health benefit.

What Does Carnosine Do?

For one thing, carnosine has anti-glycosylation properties.

To be exact, carnosine reduces the harms of a process called ‘glycation’ which involves advanced glycation end-products (AGES).

Glycation is central to the aging process and progressively damages our body, potentially leading to atherosclerosis and various other chronic diseases (19, 20).

Additionally, carnosine helps boost the immune system and reduce inflammation. The compound is also thought to help prevent lipid peroxidation within our cells (21, 22).

Key Point: Beef (and red meat in general) is the best dietary source of carnosine.

7. Beef is Full of Vitamins

There are many important nutrients in beef, and those present in significant amounts include the range of B vitamins (11);

 Vitamin Name Amount Per 6oz Portion (% RDI)
Vitamin B1282
Vitamin B350
Vitamin B636
Vitamin B218
Vitamin B514

Additionally, beef also contains smaller amounts of vitamins E and K.

Vitamin B12 (cobalamin) is a notably essential nutrient, and this is because it is only available from animal foods.

This vitamin also has a wealth of benefits that include skin improvements, positive mood, better sleep, and neural regeneration (23, 24).

It’s important to realize that insufficient vitamin B12 may also increase the risk of depression and mental health issues (25, 26).

Fortunately, a 6oz serving of beef provides almost 100% of the recommended amount of B12.

Those most at risk from B12 deficiency are vegetarians/vegans, and these groups should supplement with the vitamin.

Key Point: Beef is high in B vitamins which help promote health. Vitamin B12 is particularly important since it isn’t present in plant-based foods.

8. Conjugated Linoleic Acid

A Piece of Ribeye Steak on a Fork.

Otherwise known as CLA, conjugated linoleic acid is a naturally occurring trans-fat.

Don’t worry, although the “trans-fat” name is a little scary, it has a very different effect to the synthetic version.

Some randomized controlled studies involving human participants suggest that;

  • Conjugated linoleic acid might help to improve insulin sensitivity (27)
  • CLA may slightly promote fat loss, but the evidence is mixed (28, 29)

Notably, the bulk of the evidence suggests that getting CLA from real food is better than supplementation (30).

As is usually the case, perhaps nutrients in whole foods have a different effect to a synthetic pill?

Food Sources of CLA

The top sources of CLA include meat and dairy products.

After lamb meat and certain cheeses, beef is the next highest provider of the nutrient.

Although all beef contains CLA, grass-fed meat offers a significantly higher amount than beef from non-ruminants.

Specifically, the average amount of CLA in grass-fed beef is 0.46% of the fat content.

With grain-fed beef, this average content drops to 0.16% of fat (31).

Key Point: Beef—especially from grass-fed cows—is one of the highest sources of conjugated linoleic acid.

9. Beef Contains Creatine

Almost everyone knows the dietary supplement version of creatine, but did you know that beef contains it too?

In fact, beef typically contains 350mg creatine per 100g (32).

The health benefits that creatine bring include;

  • Improved exercise performance
  • Creatine assists in muscle growth and development
  • Provides muscles with greater energy supply and improves endurance
  • Increased muscular size

It’s also worth noting that our liver can produce about 2g creatine per day, depending on the pre-cursors being available.

Creatine precursors include arginine, glycine, and methionine (33).

Not only are all of these amino acids present in beef, but beef is one of the single most significant dietary sources for them.

In other words, eating beef gives you a decent amount of dietary creatine, and it helps your body to produce it too.

Key Point: Beef has two positive impacts on creatine levels. Firstly, it directly provides it to the body and secondly, it helps the body to make it.

10. Beef is Affordable

A Man Worrying About Money and Finances.

We may hear how beef is so much more expensive than vegetables and other plant-based foods.

For some reason, these claims often compare broccoli to beef.

However, these calculations are a little disingenuous. Yes, broccoli is indeed a lot cheaper than beef per 100g.

But just how much energy does 100g provide?

200g of beef will typically provide around 550 calories, but 200g of broccoli only contains 70 calories (34, 35).

This means that per 100g, beef contains eight times the amount of energy than broccoli.

In other words; per calorie, beef is substantially cheaper than broccoli.

Key Point: Per calorie, beef is a very affordable food – it’s cheaper than vegetables.

11. Beef is Very Simple to Make

This one isn’t a health benefit as such, but it could be if it encourages more home cooking.

Beef is a straightforward food to cook. It requires no lengthy recipe or complex preparation procedures.

Add a little salt, put it in the oven, and wait until done.

In an age where people claim not to have time to cook, a traditional dinner of beef and veggies is very simple and time-efficient.

Key Point: Beef requires minimal preparation, and it’s quick and simple to cook.

Nutrition Facts

Before we finish, the following tables show the full nutrition profile for beef per 100 grams (cooked).

Although the exact nutrient ratios will depend on the precise cut of meat, the following nutrition values are based on 80% lean ground meat (11).

Final Thoughts

Beef contains dozens of health-promoting nutrients, some of which many of us don’t consume in sufficient amounts.

While there are also some concerns about red meat, beef supplies large amounts of beneficial nutrients to the average diet.

Particularly protein, iron, zinc, and vitamin B12.

Excellent article. I posted in my Dr.Carnal FB account, but it should be available in Spanish for Latino audiences. I would be glad to translate it (giving you the credits, of course) contact me.


I’m wondering why there is no mention of one thing in particular in your article: eating grass-fed beef. My doctors, nutritionist, and trainer all recommend this.

Did you know grass fed has very little labeling control? All beef at one time are grass, very little is actually grass finished, which is apparent if it has yellow fat and very little of it. There is a lot of misrepresentation of products, just like Tyson falsely advertising no antibiotics, well that’s good since no chicken is allowed to have antibiotics! They often label things as if they are somehow different then all the other products on the shelf but they are the same other then the package label, grass finished with yellow marbling is the only one that… Read more »


If one must eat beef, yes, grass-fed is the only way to go. Organic is second.

Fantastic information


This is such an informative & helpful article. Hats off to the author!! The American schooling systems should be teaching this info, however they do not which is a shame. Thanks to the author for sharing this wealth of knowledge to others. I have a 10 month old that I feed puréed filet every week in addition to milk, other meats/fish, veggies/fruit. He’s very healthy and in the 98% for both height/weight. People ask what he eats and after telling them puréed filet, they look at me like I have 2 heads and say “I’ve never heard of that!”.

New research suggests that L-carnitine, either from red meat or taken in supplement form, poses a threat to your heart. A diet rich in red meat – pork and bacon count too – has long been recognized as a risk factor for atherosclerosis (hardening of the arteries). The saturated fat content of lean red meat accounts for only some of the increase in heart risks. Carnitine, a compound found in red meat, may now be a culprit for additional risks, says Cleveland Clinic’s Heart and Vascular Institute’s Stan Hazen, MD, PhD, and his colleagues who did the research and authored… Read more »


I had a carpal tunnel surgery last September and still experience pain in the wrist as well as swelling of the hand. However, I noticed recently that whenever I have a beef fillet steak at lunchtime, the pain and swelling disappear in addition to normal wrist functions. shortly afterwards!!!


My son has a similar effect after eating Beef, his for arms stop aching the next day after eating Beef for dinner the day before.


Great information. I advise people to consume red meat all the time. Problem is, people actually feel nauseous at even the sight of it. The media propaganda against its consumption has caused people to view it as a disease causing, unclean food. When I ask them where they get their amino acids and iron from they don’t know. People have no idea how they are harming their health.


Love the article – as always.

The controversy around beef always fascinates me. The topic seems to draw out the most extreme opinions and arguments, along with many highly emotional people. I’ve seen so many people argue for the benefits (which is my stance as well). Yet, just as many seem to argue the reverse.


Annie, many people live a carnivorous life (meat and water only) and have had nothing but positives. No cancer, no CVD, no athero, no scurvy etc etc. Give it a go, nothing but meat is giving your body a much needed retreat.


Beef is so confusing. It is one of the main contributors to climate change and almost all cardiologists advice their patients to eat or eliminate beef. Top cancer epidemiologists will tell you that research shows that plant-based diets decrease your chances of cancer. I also see the arguments for it. It’s all very confusing to me.


Annie, have you ever heard of Allan Savory and the Savory Institute? Livestock is not a main contributor to climate change. Management of grazing has turned deserts into lush grasslands.

Beef is absolutely not the main contributor to climate change more or less 2%, beef are symbiotic with their environment. The microbiome in the cows guy is the same as the soil in the grasslands and they replenish the microbes and fertilize the soil. The Great Plains evolved under large herds of herbivores rotationally grazing, the buffalo used to do the job now those millions of buffalo are replaced with beef cattle. The microbiome they replenish is is symbiotic with the root system of the native grasses! Sd cattle rancher= OG environmentalists! It is our job to be the caretakers… Read more »
