The Differences Between Grass-Fed Beef and Grain-Fed Beef

When making the transition into the Primal way of life, a lot of people get tripped up on the question of grass-fed beef. Is it necessary? (No.) Is there really that big a difference between conventional beef and grass-fed beef? (Kinda.) What does grass-fed actually mean? How do conventional cows live and what do they eat – and does that matter enough to me to make the effort to incorporate true grass-fed beef into my diet?

Hopefully, the following article will shed a bit of light on the subject, making it easier for you to make an informed decision based on your preferences, your needs, your budget, your personal ethics, and the objective information provided.

Cow’s Diet

You’d think this would be a simple, single sentence section – grass-fed cows eat grass, grain-fed cows eat grain. Bam. Done, right? Not quite.

For the most part, all cows start on grass. Well, calves drink milk, obviously, and then “milk replacement” (which appears to be a sort of high-powered protein shake made of milk proteins, lard, lactose, added minerals, and several choice supplements) upon separation from their mothers, but even the most CAFOed out cow probably started with grass before being switched to concentrated feed. Concentrated feed can mean any number of things, but the base food is always a grain slurry, typically of corn and corn byproducts (husks, cobs), soy and soy hulls, spent brewery grain, spent distiller’s grain, and other cereals. CAFO nutritionists can get pretty creative, though, sometimes including cotton byproducts, old candy (including wrappers), beet and citrus pulp, and peanut shells in their cows’ diet.

To say grass-fed cows eat grass isn’t telling the entire story. It’s more accurate to say they eat graminoids, which comprise hundreds of different species of sedges (found in wild marshes and grasslands; a famous sedge includes papyrus), rushes (a small but plucky family of herbaceous and rhizomatous plants), and true grasses (cereals, lawn grass, bamboo, grassland grass – the type of grass that produces the leaves Walt Whitman writes about). And that’s just the graminoid. Cows will also nibble on shrubs, clovers, and random leaves if they can get to them. Basically, they’ll eat whatever’s in reach, green, and leafy. Legally, grass-fed cows may also eat cereal grain crops in the “pre-grain stage,” hay, silage, and non-grain crop byproducts (one of my favorite farms gives their cows leftover veggies, for example, and it’s fantastic; that would qualify).

There’s yet another hazy category: the pasture-raised cow. These guys get steady lifelong access to open pastures, but those pastures are supplemented with feed bins containing grain feed. Not technically grass-fed, but not quite sucking down gumdrops like Grandma. Purveyors of pastured cattle who include grain in the feed are usually pretty conscientious stewards of their operation, and I’ve had great meat from cows that were fed grass and grain concurrently.

Living Conditions

While both grass-fed and CAFO cows start out on grass and milk (many of those cows you see grazing on open grassland along highways end up in feedlots eventually), only exclusively grass-fed cows live out their entire lives on grassland. CAFO cows move to feedlots once they hit 650 or 750 pounds, a weight it takes the average cow twelve months to reach on pasture. Feedlot life lasts three to four months, plenty of time to boost the animal’s weight above 1200 pounds and increase intramuscular fat deposition (marbling). Feedlots have the potential to be pretty grim places. While I’m sure “good” feedlots exist, nondescript, bleak pens crowded with sick, overweight cattle and their manure are the norm. The purpose of the feedlot, after all, is to maximize weight gain and minimize overhead. You don’t do either by recreating the cow’s natural habitat.

Whenever I drive up the I-5 to Northern California, I pass the Harris Ranch feedlot in Coalinga. The Harris ranch feedlot is the largest I’ve ever personally seen – up to 250,000 head of cattle annually, 100,000 head at any one time, about 200 million pounds of beef produced each year – but it’s actually considered to be a moderate sized feedlot. If it’s above 80 degrees, you smell the lot long before you see the signs for it. Now, I’m not citing any studies here, but I think it’s a safe assumption that cows prefer a grassy paddock to a pond of their own manure. You don’t have to care about the animal’s welfare – after all, we’re going to end up eating them – but I enjoy my meat more knowing that it comes from an honest operation that respects its participants’ living conditions.

Does it matter?

I think so. I make no bones about my primary reason for supporting grass-fed beef (I, ahem, want to eat delicious animals and buying delicious animals promotes their production), but that doesn’t mean I don’t care about their welfare while alive. I’ve been to grassland farms with families of cattle ranging, and if you get to close to a calf the mother will stomp and chase you down. I didn’t even know cows could run like that. Are they cud-chewing ungulates with minimal brainpower in the grand scheme of things? Sure, but they care about stuff in their own beefy way. And I find that pretty touching. I’ve also hiked through cattle farms and watched the cows roam and range all over for acres, contrary to the grass-fed detractor’s claim that cows prefer to be confined to a single, safe spot.


I’ve been one to bang the omega-6 in feedlot beef drum, perhaps as loudly as anyone, but I think a revisiting is in order. Simply put, while the omega-6:omega-3 ratio in CAFO beef is worse than the ratio in grass-fed beef, it’s not because the omega-6 content of beef fat skyrockets with grain feeding; it’s because the omega-3 content is basically nonexistent. The absolute totals of omega-6 in grass-fed and grain-fed are roughly similar. Grass-fed is even richer in PUFA by percentage, owing to the increase in omega-3s. As long as you’re avoiding or limiting the real big sources of linoleic acid in the diet, like seed oils, bushels of nuts, and conventionally raised poultry fat, the omega-6 content of conventional beef fat won’t throw your tissue ratios off by much (if at all). What will, however, is the lack of omega-3 fats in grain-fed. Eat some fatty fish or take some high quality fish oil to round it out.

Grass-fed beef is also higher in B-vitamins, beta-carotene (look for yellow fat), vitamin E (alpha-tocopherol), vitamin K, and trace minerals like magnesium, calcium, and selenium. Studies show grass feeding results in higher levels of conjugated linoleic acid, the “good” naturally occurring trans fat. Studies also typically show lower total levels of saturated, monounsaturated, and polyunsaturated fats in grass-fed cows, but that’s just looking at the trimmed cuts. If you look at the whole carcass post-slaughter, you’ll find it’s encased in a thick shell of saturated animal fat that gets removed because consumers are scared of it and many grass-fed producers love to market their meat as low in “bad fat” and low in cholesterol. Kurt Harris, who regularly hunts “lean” wild bucks and miraculously discovers ample stores of body fat, just put up a post dealing with this exact issue. Long story short: grass-fed beef has plenty of fat, it’s just distributed differently. More subtle marbling and more subcutaneous deposition.

Grass-fed truly shines in the micronutrient profile for one reason. Grass-fed cows get more nutritious food. Remember: they aren’t munching on monoculture lawn cuttings (let alone soy and corn). They’re eating a wide variety of (often wild) grasses, sedges, rushes, shrubs, and herbs, each with its own nutrient profile. Of course, how nutritious those graminoids are depends on the quality of the soil, or the terroir. If we care about what our food eats, we should also care about what the food that our food eats is eating, right? Grass-fed isn’t just miraculously higher in selenium because of some magic process; it’s higher because grass grown in good wild soil patrolled by plenty of mobile, self-perpetuating organic fertilizer machines contains more selenium than soybeans or corn grown on nutrient deficient land. It should follow that pastured, grain-supplemented beef raised on good soil by good ranchers also contains higher levels of micronutrients when compared to the CAFO cow, albeit not as high as the purely grass-fed.

Eat beef, first and foremost. Get the highest quality beef you can afford, whether that ends up being premium grass-finished from the farm up the road or USDA Prime from Costco. Don’t let the perfect be the enemy of the good. Man cannot live on wild caught canned sardines and crushing angst alone.

Cost and Accessibility

For the average grocery store shopper, conventional meat is cheaper and easier to get. You drive your car to the grocery store parking lot, walk twenty feet to the entrance, walk to the meat counter, balk at the $9/lb grass-fed ground round, grab a few Styrofoam containers of ground beef for a few bucks per pound instead, and you’re done. Not much thinking, hard work, or money required. This is how most people handle their meat acquisition.

If you want that same deal for the grass-fed beef, you have several options.

  • Wait for a sale at the grocery store and stock up. It probably won’t hit $3/lb, but you might save a few bucks.
  • Find a farmers’ market nearby (if any exist and the season permits) that has a grass-fed beef vendor. Hope they sell for a reasonable price, haggle if not. Buying large quantities might lower costs for you.
  • Buy direct from a farm. Search Eatwild or browse the list from this post for the nearest provider. Oh, and you’ll need a freezer to store all the meat, since you’ll have to buy in bulk to reduce costs. If you go this route, you can sometimes get a quarter, half, or entire cow for as little as $4/lb. (Hint: remember to ask for the fat!)

Each route involves more effort, more money, and/or more time. All three are worth pursuing (grass-fed is that much better, in my opinion), but I can understand why the barrier to entry appears so high – a combination of price and time. To reduce the former requires more of the latter, usually. And if you do it right and get a freezer to go with your side of beef, you’re still incurring a big initial investment. Not everyone can do that.

To my knowledge, “average” price figures don’t exist. Grass-fed from one Whole Foods can be a dollar cheaper per pound than in another Whole Foods two zip codes over; the same farmer who gives me grass-fed ground round for four bucks a pound at the Santa Monica farmers’ market might charge five dollars at the Beverly Hills market.

Bottom line? Paying $12/lb for grass-fed flat iron steak regularly isn’t worth it, to me, but spending extra time researching farms/visiting farmers’ markets/scoping out sales to obtain affordable grass-fed beef definitely is worth doing.


From 1998 to 2009, the number of serious grass-fed producers in the United States grew from just 100 to over 2,000. Market share grew in the same time frame from just $2 million to $380 million (to over $1 billion if you include imported grass-fed beef). Today, you can find grass-fed beef (and lamb and bison, even) in standard supermarkets, not just your specialty upscale grocers. Farmers’ markets are exploding (I gotta arrive earlier every weekend, it seems), and the Slow Food/locavore movements are picking up steam. Clearly, the availability of grass-fed beef is growing with growing consumer awareness and demand – funny how that works out, eh?


In the end, what else matters? The final arbiter of a food’s worthiness is always taste. Food should – must – taste good for us to eat it, especially food that is responsible for a big portion of our caloric intake. Typical grass-fed beef is intramuscularly leaner, more robust, and “beefier” than typical CAFO beef, which I find to be somewhat mushy and bland.

Still, stringy, tough, unpalatable grass-fed beef exists along with incredible grain-finished beef. I’ve had both. I’ve eaten great conventional chuck roasts purchased for a few bucks per pound at the Hispanic supermarket and I’ve had excellent steaks from Prather Ranch, a Northern California producer that goes purely grass-fed until the last few weeks of a cow’s life, when its diet is supplemented with chopped forage, rice, and barley. While good grass-fed is better than anything else, the grass-fed label can’t make up for a bad rancher (or poor foraging) and a good rancher can make up for some grain in the diet (taste-wise; perhaps not nutritionally).

For me, the clearly superior version of beef comes from the grass-fed and –finished cows raised by ranchers committed to providing excellent stewardship of both soil and cattle. Next, cows that have been grass-fed, pastured, and grain-finished by similarly committed producers with similarly maintained soil quality.

After that? Just eat beef. Whatever you can get on a regular basis. Grab the occasional grass-fed cut when you can, see how it tastes, and figure out if it’s worth it to you.

You want comments? We got comments:

Imagine you’re George Clooney. Take a moment to admire your grooming and wit. Okay, now imagine someone walks up to you and asks, “What’s your name?” You say, “I’m George Clooney.” Or maybe you say, “I’m the Clooninator!” You don’t say “I’m George of George Clooney Sells Movies Blog” and you certainly don’t say, “I’m Clooney Weight Loss Plan”. So while spam is technically meat, it ain’t anywhere near Primal. Please nickname yourself something your friends would call you.

  1. It matters terribly what kind of meat we eat. Grain fed beef is inflamed flesh. It is acidified meat. And that means when we eat it, we are consuming inflammation. Inflammation is the primary source of sickness in humans. We are eating the same industrial food diet through our consumption of essentially rotten meat. There are many other measures than Omega 3 and Omega 6 to capture this. Animals fed industrial foods are poisonous. And so are our pets who are now hugely obese as we are by feeding them industrial food.

  2. Great overview. Your comments about the omega-6:omega-3 ratio were especially enlightening. As much as I would prefer grass fed, the budget usually calls for Costco beef. It’s good to know I can offset the ratio with fatty fish and fish oil.

  3. This was a great article! My husband and I now live in Panama, Central America (from NY state) and they only have grass fed cattle here. Very tough meat but by using papaya as a tenderizer, we can have excellent steaks. I just lost 32 lbs. on a low carb diet (reaching my goal)and a friend introduced me to your books….this is the way to go!! Thanks for all the important info and I look forward to receiving your emails.

  4. Not everyone has the budget for grass fed meat. My own plan includes (soon) raising my own, but meanwhile, the difference between ‘regular’ and grass fed for the same cut is about $2 a pound vs. $8 a pound. My 92 year old wheat loving mother says people have to eat wheat because they can’t afford meat–laughable! Bread is $$ more than heap beef and way more than chicken…and it’s toxic to boot! Even the ‘worst’ meat is a better choice than any grain.

  5. I live in the NW Chicago burbs. I have gotten to know a few farmers. One farm in particular has really impressed me. The people at Meadow Haven Farm test the quality of the soil and grasses that their cattle eat. They even imported tons of crushed rock to remineralize the soil. They feed a lot of kelp to the cattle because the midwest is devoid of iodine in our soils. One of the farmers used to be a veterinarian. The first year they had a few cases of pinkeye and foot rot. A few years later the herd is far healthier due to the soil improvements.

    • I read some comments about the taste of grass fed beef. I have had grass fed meat that tasted gamey and some that did not. Over the past 2 months I have had grass fed beef from 3 different farms. One of them had the gamey meat. I’m wondering if it has to do with soil health or terrior. The beef I eat most often isn’t gamey at all, and I know these farmers and what they are doing. Interesting!

  6. Another good reason to buy grass-fed-only: feed-lot beef is so unhealthy that the only way they get them to the slaughterhouse alive is to pump them full of antibiotics…when then go into the poor fools that eat it.

    I’ve found grassfed beef to be reasonably priced, but then, I buy direct from the rancher. Now if I could only find naturally-raised chicken at a good price. I don’t mind raising my own chickens, but processing them at the end of their life is SUCH a hassle.

  7. We’re located 50 miles NW of Chicago, we sell grass-fed beef and partner with a neighbor to sell open range chicken, pork & eggs.

    We sell by the piece. As stated in your article, price is an obstacle for some wishing to eat grass-fed beef regularly, which is why we sell by the piece at a reasonable price. We want people that can’t afford a quarter, half or a whole beef to be able to enjoy the health benefits, great taste and know that the cattle they eat are raised with respect.

    Our cattle are raised on grass pastures along with brush to nibble on with an abundance of clean water winding through it. They are in NW Illinois 8 months of the year, then sent to Central IL for the winter months and fed hay and silege, they are back to the NW pasture in the spring.

    We love it when people visit our ranch, we get to share our pastures, cattle and horses with them.

    Take a look at our website,, many are surprised that there is a cattle ranch with real cowboys and working horses (Frank, my husband has 43 years experience with cattle ranching in California, Texas and IL).

    Thanks for the article, we find that many people are trying to figure out the whole grass-fed, local movement, articles like this coming from a credible author is appreciated by the people looking for grass-fed beef and the providers.

  8. I prefer to eat grass fed but don’t have regular access or funds to afford it so I have to eat grain fed beef at times. I’m gluten intolerant and can’t find anything definitive as to whether grain-fed meat is actually gluten free but I always feel like I’m eating poison when I ingest conventional beef.

    I came across this from “Grain-fed beef is fine. Before protein is absorbed it’s broken down into single amino acids or very short peptide fragments-no longer gluten.” — Tricia Thompson MSRD

    Because I find this hard to believe even though I have no background or education to back myself up, I’m looking for scientific studies that will. Can anyone point me in the right direction? ~ A girl cannot live on salmon cakes alone!

  9. This article is great. People should know that it is cheaper in the long run to buy cases of exactly what you want to eat as opposed to buying a half of beef. Buying cases of what you use eliminates cuts of beef, lamb or pork that sit in the freezer for long periods of time until you finally feed them to your dog. People do not usually call cattle ranches, farms and most ranchers do not like to be called farmers. When there is a cow and calf in the field they are called cattle. More than one calf is considered calves. Prather Ranches have a lot to offer a consumer.

  14. Neither you nor any of your commenters mentioned the presence of hormones or antibiotics in conventionally raised beef. I would gravitate towards farm raised or grass fed because the greatest majority of these types of farmers avoid using these toxins. An oncologist friend counsels eating “conventional” beef no more than once a month because of that reason.

  15. Interesting article. I’ve never tasted grain fed beef so I’m interested in how big the taste difference is? I’m in New Zealand and our cows live outside in paddocks year round and eat grass mostly, sometimes hay as supplementary feed. I’ve heard of grain fed beef advertised here as a specialty product but it is more expensive than regular free range beef. How big is the difference in taste between grass fed and grain fed beef? Does grain fed beef taste unpleasant, or different but nice?

  16. in rural india, life is hard and driven more by necessity than anything else. my mother, not equipped with too much more than native intelligence, used to run a small dairy farm. green fodder was hard to come by. rains were always inadequate, fodder was expensive and scarce. cheap grain based cattle feed was being actively promoted by both govt and commercial producers.
    even while she bought cattle feed, my mother always ensured her cows had green fodder when available, then dry fodder. the milk was tastier, she said, and the animals healthier.
    you don’t need nutritionists or anybody with fancy degrees to tell you this… even small farmers know it. grass is a cows natural food. grass fed animals are healthier.
    what kind of meat you buy is your choice. but what more do you need to know really?

  20. You North Americans have no idea how good you have it.

    Japanese beef STARTS at $12/lb and goes up to $80/lb. Grain fed from what I have learned.

    On the plus side, Aussie beef is available everywhere and mostly grass fed, and here we can get it starting around $6-7/lb for the cheaper cuts.

    The little US beef we do find is unlabeled, so no doubt it is grain fed. Costs about the same as the Aussie stuff.

    Interesting note that Japan had a ban on US beef for a long time due to BSE worries. US producers refused to test for it, even though the Japanese buyers were going to pay. Aussies won out since they don’t rely on “feed”.

  21. Mark, Need to clarify a few things. Here in NW Wash, we have many small farms who raise pasture beef. Fed totally on grass or grass hay. No grain. And never fed milk replacement as calves like dairy calves.. They nurse their mamma. Of course we have super perennial pastures and many have irrigation. Our calves at 12 mos avg 8-900 lbs. At slaughter, 18-24 mos they will weigh 1100-1200 lbs. Outstanding meat with unbeatable flavor cooked MR or better rare Yes, range raised beef may require feedlot to finish, but ours don’t and grain fed tastes offbeat once you eat the total grass fed meat. Also we have a local USDA slaughter house to our meat is sold by the piece, at a very reasonable price. E.G. Sirloin steak at $6.50 /lb.

  24. You can get the “$3″ a pound grass finished beef by buying a whole or half beef here in the DC-area. But that price doesn’t tell the whole story. You will have to pay for butchering and packaging and there is loss on that carcass weight. So, when it comes time to put it in the freezer, the $3 a pound hanging wt beef is going to cost you closer to $4.50 a pound. Worth every penny, of course! I sell grass finished beef by the carcass or the quarter or the pound in the DC area.

Both are pretty easy and cheaper than you might think. Heritage breed animals are healthier for you and lower cost to raise. Small “closed” herd and flock so no antibiotics have ever been needed. Look for Highlanders-get healthy food anf help preserve the breed!

  31. educate yourself about what grass is before you buy organic
    an articale from Claravale Farm: a traditionally run dairy and we don’t think total pasture feeding of dairy cattle is appropriate for a number of reasons.
    Contrary to popular belief, total, year round pasture feeding is not natural for cattle and is not the way in which dairy cattle have historically been managed. More typical is for dairy cattle to get access to some pasture during the natural growing season (winter and spring here) and to be fed mostly hay, grain and other produce during the rest of the year. This is what we do at Claravale. In this way, farmers have historically taken advantage of natural yearly cycles of rainfall and production. Year round pasture feeding of dairy cows requires the artificial creation of year round pastures by intensive irrigation, which requires energy and water, both limited resources in California.
    Here are a couple of important facts for people who are not agriculturally inclined:
    Hay is dried pasture.
    Grain is grass seed.

    All three of these feeds (hay, grain, pasture) are completely natural and important feeds for dairy cattle. All three are historically important feeds for dairy cattle. All three have been important components of the diets of dairy cattle for the entire history of their existence on this earth. A cow grazing on a naturally cycling pasture (in California, for example) will be eating green pasture for part of the year, but as that pasture matures and dries out the cow will continue to eat it but it will now be called standing hay (= hay). As the pasture matures the grass forms seed heads (= grain) and dries out. When this happens, the nutrition in the leaves and stems decreases and the nutrition in the seeds (= grain) increases. During much of the year, a cow grazing on a naturally cycling pasture will be getting a large percentage of its nutrition from this grain (= grass seeds).
    A good quality, high producing dairy cow cannot do well on green pasture alone. Even the best pasture does not contain the nutrition it needs to produce the milk it was bred to produce. (Important note: this is different than for beef cattle that can do just fine on green pasture alone. Beef cattle only put on a few hundred pounds of weight in their lives. Dairy cattle do this as well and produce thousands of gallons of milk every year in addition.) By adding hay and grain to the diet of dairy cattle you are simply feeding them concentrated pasture. By drying pasture into hay the nutrition it contains is concentrated ten fold. Dairy cattle, however, need even more than this. To do well, dairy cattle need the best cuttings of the best hay possible. Hay that tests the highest in nutrition is referred to in the trade as ‘dairy test’. It costs a premium and is reserved for dairy cattle.
    Even given the best, most nutritious, feed possible, many cows still lose weight during the early stages of lactation. If dairy cattle are not given the nutrition they need they will be severely stressed and will be susceptible to many infectious and metabolic diseases. The cows will suffer as well as milk production and milk quality. For example ketosis and hypocalcemia are both common metabolic diseases in dairy cattle that are caused by inadequate nutrition during lactation. Both of these diseases can kill cows very quickly.

    Cows are very smart about food. They are expert at sniffing out (literally) food that is best for them. Cows do not want a diet of green pasture alone. Given long term free access to pasture, hay and grain they will eat lots and lots of hay and grain.
    Historically, no dairy based culture has ever tried to artificially create year round pastures to feed dairy cattle. It makes no sense with respect to cow nutrition, water use, or energy input. Historically, farmers work with the natural cycles, utilizing green pasture when it is available and at its height of nutrition but also harvesting this pasture when it is at its height, concentrating it, and feeding it to the dairy cattle the rest of the year (that is, they make hay and store it in the barn). They also harvest grain and store it to feed to the cattle throughout the year.
    This is what we do at Claravale. We utilize naturally cycling pastures during the time of the year that it makes sense (up to seven months out of the year here in Panoche) and also feed the cows high quality organic hay and grain. We are proud of how we care for our cows at Claravale. We are proud of how healthy they are and the quality of the milk they produce. We don’t pretend to do something we don’t.
    In addition, grass fed cows produce milk that has an “off” flavor. The older literature contains many references to the fact that cows which are on pasture produce milk which tastes bad. It is usually recommended in this literature that the cows be taken off of the pasture for a few hours before milking to limit this effect. These days, this is not a factor with most milk producers (including organic milk producers) because the milk is cooked and processed before sale so it doesn’t taste good anyway. The effects of the grass on milk taste will be masked by the effects of all the other processes. Every year when our cows do get some pasture we always get complaints about the taste of the milk. At Claravale Farm, taste is an important component of quality so we don’t totally grass feed our cows, but rather give them a varied, traditional diet designed to keep them healthy while producing delicious milk.

  32. Just had my first grass fed beef steak. It was delicious. Tender , juicy and very tasty. I have to admit I was very skeptical about eating it. Now that will be all I will be eating.

  33. Dear Mark,
    Thanks for your great website which was my doorway into the world of nutrition blogging and one which I refer to a lot.
    I have a few questions that I hope you can take the time to answer:
    I live in India where paleo/primal nutrition is unknown (although traditional Indian foods are very primal) and the health conscious public is sold industrial oils blatantly claiming to be heart friendly.

    However I found that India is great for a few things:
    1) COCONUT OIL! at $3 per kg.
    2) Ghee at $5 /KG.
    3) Beef at $3 /kg.
    4) Tallow for free!
    5) Buffalo milk with 6% FAT!
    6) Fine quality partially grass fed mutton at $9 /kg.
    Spices and vegetables are also cheap.

    However there are a couple nagging doubts that I have.
    1) No beef is grown commercially in India.
    The beef available is mostly older water/buffaloes cows or younger bulls/bullocks.
    I tried looking at the diet of these animals and it seems that the male animals/older animals are mostly pastured but especially so during the 4 month long monsoon when green grass is free. Bearing this in mind, should I be buying ghee during the first month of the monsoon when animals feed on growing grass, or after they have had a 4 month diet of green grass, that is, in September at the end of the monsoon.
    Also as far as tallow goes, would the older animal tallow be more nutrient rich? Would there be a greater accumulation of toxins? should I buy calf tallow or Old animal tallow? (The older animals seem to have a yellower tinge.)
    Also, I looked at pollution levels in the Arabian sea and they seem to be reasonably low. Would it then be wiser to get more of my protein calories from ocean sourced Indian salmon/King mackerel/Tuna/Shrimp which are each about $2 per pound or beef which is closer to $2 per kilo but has an unknown diet?

    I eagerly await your response.

    The good has long since become extinct, if we don’t demand the perfect, we will lose it all.

  35. What about the pesticides, hormones, and antibiotics in CAFO animals? Is this primal? Hardly. It reeks havoc on your gut microbes among other things.

    2.3 Paleo Approved Banned Feedstuffs List

    The following is the list of banned feedstuffs in the Paleo Approved from Pasture to Plate Program. Paleo Approved may revise this list if deemed necessary by Dr. Loren Cordain, Dr. Mathieu Lalonde, Dr. David Pendergrass, or Paleo Approved expert consultant with future research review. Prohibited feedstuffs include:
    Cereal Grains
    Milk replacers containing antibiotics and growth hormones
    Non-protein sources of nitrogen
    Animal by-products
    Feedstuffs containing animal protein sources with the exception of those

    from milk and milk proteins prior to weaning.

  36. Some clarification: first, you don’t eat many “cows”, especially if you are eating steaks. Steaks come from steers and slaughter heifers. “Cows” are generally ground up into hamburger. Second, the vast majority of calves do NOT recieve “milk replacer”…the only calves that ever get “milk replacer” are dairy calves, and not many steaks you see in the store will have come from a dairy calf. I quit reading after that as the credibility of this story is totally shot.

  37. As a resident in New England it is very difficult to find local purely grass fed meat. Any all pasture fed meat recommendations that ship? Thanks

    • Have you looked on There are dozens of grass-fed farms in New England.

  38. Living in some of the prime beef raising country in the world, our families have raised beef for more than 50 years. We have tried a lot of different approaches but the one tried and true is grass fed to 700-800lbs, no hormones, antibiotics only for illness or injury not for yield increases (like feed lots do)…on that point what are you to do as a farmer? Not give the animal support for their injury? You wouldn’t like that if every human injured was just left to fend for themselves. Point SHOULD be no “unnecessary or over usage of antibiotics”. So 98% of our beef has always been “no antibiotics”. Do you really believe your life is worse because you took a 10 day series of antibiotics when YOU were sick?

    While I agree that large feedlot operations are disgusting exhibits of what large commercial agriculture provides I have to disagree with some that say a final finish of grain is so detrimental…I believe its balance in everything.

    Hard as you try grass FINISHED will generally be more stringy, tougher, less marbling and while possessing more of the natural taste(which I prefer), can be added to with just a few weeks of molasses and pure grain mixes.

    Specifically when you go to small lot(grass pasture WITH custom blended daily grain kicker) the animals are getting a premium diet. Isn’t that what most of you on this board are seeking for themselves? A more complete diet?

    As one of the other posters above mentioned pastures NATURALLY change with the years cycle…in spring we primarily have very lush fescue, bluestem, lespedeza with a bit of Bermuda with several other dozen species of natural prairie grasses. But over the season several of these seed out…when they do they animals CHOOSE to eat the seed heads over the stems as they grow hay like….they know what they want to eat/what their body needs and they get muscular,fat and healthy on their own.

    So while you can overdo grain its an overstatement to say that its not a natural part of their diet….not to be rude but those are just the words from city folks who don’t know. Besides I would bet that many of the “grass fed” animals are actually grazing on maise, soybean or other crop types that are standing(not harvested). No practical difference.

    So while farm raised and farm finished IS far superior to the large commercial operations, the inclusion of organic grain on top of grass will give you a tastier beef who is healthier because it has SUPERIOR nutritional support.

    Any REAL farmer can tell you….
    a balanced approach is always superior. …someone trying to fill a niche market or charge high premiums will try to convince you otherwise.

  39. Just a side note…
    I noticed that you recommended buying USDA Prime if it’s all you can afford. The USDA grading system indicates ‘Prime’ grade as having 8% intramuscular fat marbling or higher, ‘Choice’ as 5-7% marbling, and ‘Select’ as 3-4% making it the leanest of the three. So choosing a Select grade might be the better option, or at least it mirrors a grass-fed profile a little closer.
