Farm animals are much closer in body size to humans and share similar developmental patterns of skeletal muscle and adipose tissue, making them advantageous models for studying pathophysiological conditions in humans. The American Journal of Clinical Nutrition, 90(1), 106-115. (UCPs = uncoupling proteins). If you reference the above chart concerning leucine content and protein sources, it’s easy to see that plants and whey protein could deliver similar amounts of leucine, you just have to take in more plant protein. Sedentary adults. Bjørnsen, T., Salvesen, S., Berntsen, S., Hetlelid, K. J., Stea, T. H., Lohne‐Seiler, H., … & Haugeberg, G. (2016). However, this doesn’t account for the increase in protein breakdown that occurs following training. Van den Maagdenberg, K. Claeys, E. Stinckens, A. Skeletal muscle mainly uses carbohydrate and lipids for energy production to support various biological functions, including growth, physical activity, and thermogenesis.

Since the plant-based community seems to be quick to point out shortcomings and conflicts of interest in research that doesn’t support their bias, let’s take a critical review at this piece. Pennings, B., Boirie, Y., Senden, J. M., Gijsen, A. P., Kuipers, H., & van Loon, L. J. I also hope to see improvements to the scale, but I’m skeptical that any improvements would skew the data towards favoring plant proteins due to many of the issues we’ve already discussed above. Growth of animal tissues results in formation of key food products such as meat which consists of muscle and connective tissues. Postnatal muscle growth is an important aspect of animal production because it influences the performance traits. In contrast to humans and nonruminants, which absorb monosaccharides in the small intestine, ruminants absorb short-chain fatty acids due to the extensive rumen fermentation of carbohydrates (Huntington, 1997). Body temperature homeostasis is maintained by heat production which relies on both shivering and nonshivering thermogenesis (Figure 4). Buys, N. and De Smet, S. 2007. In rodents, brown adipose tissue in the interscapular region remains throughout their lifespan. With research experience in animal science and cell and molecular biology, he developed his independent research program at the University of Arkansas to focus on the function of mitochondria in muscle growth and meat quality. Overall, fewer amino acids from plant proteins are used for muscle protein synthesis (29). Myogenic precursor cells surrounding primary muscle fibers profoundly proliferate to increase their numbers and then fuse to form secondary muscle fibers (Beermann et al., 1978). Consequently, muscle development can be divided into primary and secondary myogenesis, which occurs primarily during the embryonic and fetal stages, respectively. Dr. Min Du is a Professor and Endowed Chair in the Department of Animal Sciences at Washington State University (WSU). Satellite cells are activated by a multitude of growth factors and cytokines, including 2 key mediators of muscle growth, IGF-1 and fibroblast growth factor (FGF)-2. The American Journal of Clinical Nutrition, 78(2), 250-258. Compared with brain and heart tissues, skeletal muscle has a lower priority for nutrient repartitioning, which makes the development of skeletal muscle especially vulnerable to nutritional changes. A recent article (read here) has caused a decent stir in the nutrition community – especially coming from those on the plant-based side. He originally came from China, with a BS in Food Quality and Safety, and a MS in Meat Science. On the other hand, enhancing energy expenditure in skeletal muscle contributes greatly to the maintenance of whole-body energy homeostasis and metabolic health. Essential amino acids are primarily responsible for the amino acid stimulation of muscle protein anabolism in healthy elderly adults. These committed myoblasts proliferate and fuse to form primary muscle fibers under the control of myogenic regulatory factors (MRFs), including Myf-5, Myo-D, myogenin, and MRF-4 (Buckingham et al., 2003). Relationship between animal protein intake and muscle mass index in healthy women. Nutritional intervention which enhances myogenesis and intramuscular adipogenesis while suppressing fibrogenesis may improve animal production efficiency and meat quality. Skeletal muscle is mainly comprised of muscle fibers, connective tissues, and intramuscular adipose tissues. However, studies do show that plant protein can be beneficial for growth, there’s just one caveat: you have to eat more! Leser, S. (2013). Since glycogen content determines ultimate postmortem pH which affects meat quality, a higher proportion of glycolytic myofibers reduces ultimate pH and water holding capacity of meat. Rome, Italy. Effect of age, muscle type, and insulin-like growth factor-II genotype on muscle proteolytic and lipolytic enzyme activities in boars1. Therefore, the overall potential of a protein source to encourage muscle growth is dependent on its quality and overall anabolic potential. Let’s only point out potential conflicts of interest when it supports your bias, huh? Several types of exercise can induce protein breakdown, so protein intake now has to account for both repair/replacement and addition of muscle proteins. Consequently, nonruminants and humans use glucose and long-chain fatty acids as the principal sources of energy, whereas ruminants mainly utilize volatile fatty acids. Collectively, sarcopenia and dynapenia can alter energy metabolism and lead to the loss of physical function, ultimately manifesting as functional disability. In addition, fish eating a plant protein diet compared to a normal fish chow diet actually experienced decreases in muscle fiber size (27). That’s about it. We haven’t even gotten past the abstract and we’ve already hit a speed bump of bias. However, up to now, our understanding of the origins and mechanisms that regulate intramuscular adipogenesis remain rudimentary. So, now begs the question, who is this protein intake sufficient for? Accompanied with adipogenesis, fibrogenesis is also active during the fetal stage and generates connective tissue which forms primordial endomysium, perimysium, and epimysium in skeletal muscle during late gestation. Digestive enzymes reduce quality differences between plant and animal proteins: a double-blind crossover study. Journal of Applied Physiology, 106(6), 2040-2048. Journal of Animal Joy, J. M., Lowery, R. P., Wilson, J. M., Purpura, M., De Souza, E. O., Wilson, S. M., … & Jäger, R. (2013). (2012). He obtained his PhD from Iowa State University. Understanding the contribution of skeletal muscle to whole-body energy expenditure and heat production may help identify new treatments for obesity and associated metabolic syndromes in humans, and also increase feed efficiency in farm animals, especially beef cattle and sheep. Journal of Strength and Conditioning Research. Meat Science, 92(3), 174-178. Due to the similarity in size, gestation length, and maternal burden, sheep are commonly used as models for fetal programming studies, even though the gestation length of sheep is only about half that of humans. In humans, a portion of fibro/adipogenic progenitors are located in the interstitial region between muscle fibers, which is responsible for fatty infiltration and fibrosis production in diseased or disordered skeletal muscle (Joe et al., 2010). However, this source is only used to support a single claim that aligns well with other claims throughout the article. Since the comparison between plant-based and animal-inclusive diets can quickly spiral out of control, it’s worth taking a second to assuage tempers on both sides before delving deeper. (2012). Antagonists of myostatin, a blood-borne negative regulator of muscle growth produced in muscle cells, have shown considerable promise for enhancing muscle mass and strength in rodent studies and could serve as potential therapeutic agents for human muscle diseases. Gardan , D , Gondret , F , Van den Maagdenberg , K , Buys , N , De Smet , S , Louveau , I 2008 . Fetal programming, also called developmental programming, describes the response of organisms to challenges during a critical developmental time window that alters the trajectory of development qualitatively and/or quantitatively with resulting persistent effects (Barker, 1997). Growth can absolutely be achieved on a plant-based diet, however, specific steps must be taken to maximize growth – just like consuming a diet with both animal and plant sources. Since skeletal muscle accounts for approximately 40% of total body mass in large mammals, a small disturbance in muscle thermogenesis may contribute substantially to the total energy expenditure of the whole body, especially in adult animals when the contribution from nonshivering thermogenesis of brown adipose tissue is negligible. All other factors are for arguments far outside the scope of this article. If you’re interested in a more in-depth discussion, check out the extensive review by van Vliet, Burd, and van Loon (2015) here. This documentary opens your eyes to the troubles with keeping wild animals in captivity through. In sheep, our previous studies showed that both maternal under- and over-nutrition during mid-gestation decreased myogenesis during fetal development, but only over-nutrition increased intramuscular fat deposition. Sports Medicine, 36(4), 293-305. Therefore, greater protein (and leucine) intake is required to account for both repair/replacement, and addition of new muscle proteins. Journal of the International Society of Sports Nutrition, 12(1), P26. Tipton, K. D., Ferrando, A. Animal proteins consistently score higher than plant proteins (15,22). Wolfe, R. R. (2002). Obviously, no matter your dietary preferences, you’re going to have to increase daily protein intake to support muscle hypertrophy. This is why we see increased recommended daily intakes for athletes and/or bodybuilders. A well-known consequence of aging is the loss of skeletal muscle mass and strength, which are often referred to as sarcopenia and dynapenia, respectively (Clark and Manini, 2008). Decreased density and disrupted function of satellite cells are associated with impaired regenerative capacity and muscle degeneration due to diseases or disorders (Fukada, 2018). Moreover, compared with other common cattle breeds, Wagyu and Angus have similar growth characteristics. Nutrition Journal, 3(1), 22. Physiol, Identification and importance of brown adipose tissue in adult humans, Meat science and muscle biology symposium: manipulating mesenchymal progenitor cell differentiation to optimize performance and carcass value of beef cattle, Fetal programming of skeletal muscle development in ruminant animals, Maternal obesity, inflammation, and fetal skeletal muscle development, The roles of muscle stem cells in muscle injury, atrophy and hypertrophy. Many studies only examine protein synthesis, rather than overall protein balance. Fibroblasts also produce enzymes to catalyze collagen cross-linking which contributes to the background toughness of meat. Paddon-Jones, D., Short, K. R., Campbell, W. W., Volpi, E., & Wolfe, R. R. (2008). But trying to apply it to athletic and/or bodybuilding populations is just silly. We can’t worry about that forever, though, so let’s get started. Fouillet, H., Juillet, B., Gaudichon, C., Mariotti, F., Tomé, D., & Bos, C. (2009). Postexercise net protein synthesis in human muscle from orally administered amino acids. This acute increase in muscle protein synthesis has also been shown to affect gains in the long term. Again, ethics and morality are far from the contents of this article. Therefore, it’s certainly worth looking into what the exact differences between these protein sources are. Studies that provided higher amounts of both milk and plant proteins to subjects after a workout saw similar gains in lean mass over the long term between protein sources (6,11). Du, M., X.Yan, J. F.Tong, J.Zhao, and M. J.Zhu. Bone - Growth. When tissues or organs are actively developing, they are susceptible to nutrient fluctuations. Nonshivering thermogenesis was also found in skeletal muscle, where uncoupling protein 3 facilitates metabolic adaption and lipid metabolism and may function through a different mechanism from uncoupling protein 1 (Boss et al., 1997) (Figure 4). Ectopic lipid accumulation can be separated into intramuscular and intramyocellular deposition. Since a higher amount of plant protein was used, the necessary leucine threshold of 2-3g was met (17,26). Effects of maternal nutrition on fetal skeletal muscle and adipose tissue development of both beef cattle and humans. Chronological difference of adipogenesis in different depots of beef cattle. About Press Copyright Contact us Creators Advertise Developers Terms Privacy Policy & Safety How YouTube works Test new features However, the role(s) that uncoupling protein 3 and sarcolipin play in thermogenesis of skeletal muscle in large mammals including humans and ruminants remain largely unexplored and requires further study. However, in humans and ruminants, brown adipose tissue is only abundant in neonates, and brown adipose tissue is replaced by white adipose tissue (Symonds, 2013). GLUT4 is reduced in slow muscle fibers of type 2 diabetic patients: is insulin resistance in type 2 diabetes a slow, type 1 fiber disease? And that’s not at all the case. muscle weight, as the animal approaches maturity, without an increase in muscle fiber size can be partially explained on the basis of intra-muscular fat deposition (McMeekan, 1940b). The Journal of Nutrition, 145(9), 1981-1991. This theory has been somewhat confirmed in studies showing that soy protein causes a much greater increase in amino acid oxidation compared to milk protein when both are consumed in the same amount (35). The protein sparing function of the gut and the quality of food protein. In acute ingestion, soy protein does not increase protein synthesis to the same degree as whey protein (24), skim milk (33), or beef (21). Wilkinson, S. B., Tarnopolsky, M. A., MacDonald, M. J., MacDonald, J. R., Armstrong, D., & Phillips, S. M. (2007). Several plant-based dieters have lauded this paper as the “truth” that the omnivorous community is choosing to ignore. Tipton, K. D., Gurkin, B. E., Matin, S., & Wolfe, R. R. (1999). Protein shakes promote muscle growth so you can build lean muscles as you work out. Regul. Though ruminants and humans exhibit different characteristics in carbohydrate and lipid metabolism, they share similar regulatory mechanisms. Protein quality is highly related to EAA and leucine content and, up until recently, was measured by the PDCAAS scale, which stands for Protein Digestibility Corrected Amino Acid Score. Du, M., J.Tong, J.Zhao, K. R.Underwood, M.Zhu, S. P.Ford, and P. W.Nathanielsz. 3) Muscle mass is predicated on the balance between muscle protein synthesis and protein breakdown (29). Fibrosis disrupts muscle homeostasis, weakens muscle contraction force, and impairs its metabolic function. Phillips, S. M. (2012). The Journal of Nutrition, 132(1), 125-133. With the winter months approaching and grow season in mind, I want to tackle some productive things you can be doing to maximize muscle growth in the off-season. Farm animals can be easily sampled by muscle biopsies at different stages of development and can serve as excellent models for studying intramuscular adipogenesis. Ingestion of whey hydrolysate, casein, or soy protein isolate: effects on mixed muscle protein synthesis at rest and following resistance exercise in young men.

Dr. Yan Huang is an Assistant Professor in the Department of Animal Science, University of Arkansas. Oh, and one more thing – the plant based community often seeks to declare conflicts of interest and/or bias when reading studies that don’t support their “side.” Yet, they seem to have glossed over the fact that the primary investigator of this review is the, “… scientific leader of a research contract with Terres Univia, the French Interbranch organization for plant oils and proteins.” Hmmm.

The Journal of Nutritional Biochemistry, 10(2), 89-95. Positive protein balance elicits increases in muscle size and is driven by an increase in protein synthesis (32,34). Futile calcium cycling between sarcoendoplasmic reticulum is an important mechanism of nonshivering thermogenesis in muscle (Clarke et al., 2012). Distinct anabolic signalling responses to amino acids in C2C12 skeletal muscle cells. The resident fibro/adipogenic progenitors are responsible for adipose homeostasis in adult animals (Jiang et al., 2014). Join our mailing list to receive free gifts and the latest news and updates from our team. However, dysregulation of these progenitor cells is correlated with muscle atrophy, fatty infiltration, and fibrosis. Bos, C., Juillet, B., Fouillet, H., Turlan, L., Daré, S., Luengo, C., … & Gaudichon, C. (2005). Nutrition Bulletin, 38(4), 421-428. Plan on eating at least 30g of plant protein at each meal to maximize muscle protein synthesis and try to avoid antioxidants around your workouts as much as possible. Thus, reducing fibrogenesis during muscle development contributes to the reduction of meat toughness (Du et al., 2013). The discussion on older adults can likely be better compared to athletes and bodybuilders. No one is here to change anyone’s mind about anything, we just want to talk facts. Specifically, satellite cell proliferation and differentiation are stimulated by IGF-I, whereas FGF-2 stimulates proliferation but inhibits differentiation ( Allen and Boxhorn, 1989 ; Greene and Allen, 1991 ; Byrne et al., 2000 ). Because muscle and adipose tissues develop during specific stages of gestation (Figures 2 and 3), the long duration of gestation and lactation in ruminants (especially beef cattle) allows stage-specific nutritional interventions to enhance animal growth performance and meat quality. Impacts of early muscle development on animal production and human health are indicated. Under insulin resistance states such as obesity, diabetes, aging, and physical inactivity, skeletal muscle showed reduced oxidative capacity and increased glycolytic capacity (Gaster et al., 2001). While this doesn’t quite reach the threshold of the protein spread theory (estimates how much additional protein one would need to make better gains, read here), it’s certainly an interesting difference. It is estimated that by 2060, nearly one in four individuals in the United States (94 million) will be over the age of 65 (Vespa et al., 2018). Paddon-Jones, D., Sheffield-Moore, M., Zhang, X.
