In recent years, the trend towards consuming grass-fed beef and pasture-raised pork has gained momentum, driven by a growing awareness of the health benefits associated with these types of meats. This shift in dietary preferences not only supports regenerative farming practices but also provides a plethora of nutritional advantages that are often absent in conventionally raised meat. At this point, the research is very thorough and demonstrates that beef and lamb from 100% grass-fed systems and pigs and chickens raised on pasture produce a nutritionally superior product compared to confinement and indoor-raised animals.Â

Understanding the Nutritional Profile
One of the most significant benefits of grass-fed beef and pasture-raised pork is their superior fatty acid profile. Grass-fed beef, for instance, boasts a higher concentration of omega-3 fatty acids compared to grain-fed beef. Omega-3s are essential fats that the body cannot produce on its own, known for their role in reducing inflammation, supporting heart health, and promoting brain function. Similarly, pasture-raised pork is typically higher in omega-3 fatty acids as well, largely due to the pigs' natural diet of grass, roots, and other foraged plants.Â
Don’t be fooled by conventional literature stating that feedlot beef is higher in Omega-3s (which is true) because there is a nuance here. Feedlot-raised beef generally has more fats so it also has more omega-3; however, these fats have an imbalanced omega-6 to omega-3 ratio, which can contribute to a variety of health issues, including chronic inflammation and heart disease. By choosing grass-fed and pasture-raised options, consumers can significantly improve their fatty acid intake, promoting better overall health.
As a consumer myself, who had the privilege of receiving an M.S. in Animal Science where I had to take classes on lipid and carbohydrate metabolism, I learned that this is complex and that there is a lot to know here when making healthy decisions for yourself or your family.Â
Another nuance that is often overlooked is a fear of saturated fats. Bear with me for a second - it’s important to know that all of the fat we eat is packaged into cholesterol in the liver, and transported around our bodies to provide nutrition to our cells. 75% of your body’s cholesterol comes from the fat you eat and not from dietary cholesterol, which is why the fats you eat are so important.Â
There are different types of saturated fats and their names change based on how many carbon molecules are in them. 100% grass-fed beef and lamb is primarily high in Stearic acid, which is 18 carbons long, and has no net positive or net negative impact on our cholesterol metabolism. Meaning it doesn’t give rise to the less desirable cholesterol LDL (low-density lipoprotein). Contrast this with feedlot and grain finished beef and lamb with the primary saturated fat being Palmitic acid, which is 16 carbons long. Both are solid white fats at room temperature but they interact very differently in our bodies. Palmitic ends up primarily as LDL.Â
Don’t get me wrong. We need LDL, but it needs to be in balance with the smaller and denser cholesterol HDL (high-density lipoprotein). Less than 3.5:1 for LDL to HDL is good.Â
This is one of the primary reasons natural food advocates are promoting no-seed oils and focusing on grass-fed ruminant meats and fats.Â

Fat-Soluble Vitamins
Another area where grass-fed beef and pasture-raised pork shine is in their content of fat-soluble vitamins. These nutrients, which include vitamins A, D, E, and K, play critical roles in various body functions, from maintaining good vision and skin health to providing immune support and aiding in blood clotting. Grass-fed meat is often richer in vitamin A (in the form of beta-carotene), as the animals consume a diet rich in nutrient-dense grasses. It is also higher in Vitamin E, a potent antioxidant. Grass-fed beef often has a longer shelf life in the literature, primarily due to the increase in Vitamin E preventing oxidation in the butcher case.
Furthermore, pasture-raised pork has been shown to contain significantly higher levels of vitamin D compared to conventionally raised pork. This vitamin is crucial for bone health, immune function, and mood regulation. The enhanced nutrient profiles of grass-fed and pasture-raised meats can be directly attributed to the animals' diets and living conditions, which allow for more natural nutrient absorption.

Plant Phytonutrients and Antioxidants
This field of research is emerging and Dr. Stephan van Vliet at Utah State has helped lead the way. Interestingly, grass-fed beef and pasture-raised pork can also be sources of plant phytonutrients, including antioxidants. When the livestock forage on fresh grasses and plants, they absorb not only macronutrients but also beneficial compounds such as carotenoids, flavonoids, and other antioxidants. These phytochemicals play an essential role in combating oxidative stress and reducing inflammation in the body.
The quality of the forage significantly influences the concentration of these phytonutrients in the meat. Grass-fed animals that roam freely in diverse pastures tend to have higher levels of antioxidants, which can contribute to improved overall health for those consuming the meat.
Dr. van Vliet’s work has demonstrated that feedlot animals are effectively living immune-suppressed lives based on meat quality analysis which means we are too when eating their meat. According to this body of work, many of the most important plant-based nutrients are completely absent or very low in feedlot beef compared to grass-fed beef. Pigs eating forage while on pasture will also benefit from the nutrients in the green plants.Â
Â
The Impact of Management Practices
The traditional practices of livestock management also have a profound impact on the nutritional quality of meat. Animals raised in confined animal feeding operations (CAFOs) are often subjected to a diet primarily consisting of grains, which alters their natural nutrient profiles. This kind of intensive farming not only compromises the fatty acid composition and vitamin content but also raises concerns about animal welfare and environmental sustainability.
Animals in feedlots are fed concentrated energy feeds, such as grains high in palmitic acid, resulting in meat with elevated levels of this fatty acid, which contributes to higher LDL cholesterol—a saturated fat that doctors often recommend reducing due to its association with health risks and its role in creating an imbalanced omega-6 to omega-3 ratio.
In contrast, responsible grazing management for grass-fed beef and pasture-raised pork mimics the natural behavior of these animals, allowing them to forage for diverse plants. This holistic approach not only enhances the nutritional quality of the meat through the wild forages they eat and the exercise they get but also benefits the environment by promoting biodiversity, improving soil health, and sequestering carbon. We have improved our soil organic carbon by 27% over the past 4 years at our recently transitioned farm.Â

Conclusion
The health benefits of grass-fed beef and pasture-raised pork extend far beyond taste; they offer significant advantages regarding nutrient density, fatty acid profiles, and overall health impact. As consumers become more discerning about the quality of their food, understanding the differences between conventional and sustainably raised meat becomes essential for making informed choices. By opting for grass-fed and pasture-raised options, individuals not only support better health for themselves but also champion responsible farming practices that benefit the environment and animal welfare.Â
