Protein-enriched products are ubiquitous, and nowadays it appears protein might be infused into something – even water. However the issue, as Kristi Wempen, a nutritionist at Mayo Clinic, points out, is that “opposite to all of the hype that everybody wants extra protein, most People get twice as a lot as they want.”
Many people dwelling in probably the most economically developed nations are shopping for right into a myth of protein deficiency created and perpetuated by meals firms and a wide selection of self-identified well being consultants. World retail gross sales of protein complement merchandise – often containing a mix of whey, casein or plant-based proteins similar to peas, soy or brown rice – reached a staggering US$18.9 billion in 2020, with the U.S. making up round half of the market.
I’m a food historian and just lately spent a month on the Library of Congress attempting to reply the query of why we’ve got traditionally been – and stay – so centered on dietary protein. I needed to discover the moral, social and cultural implications of this multibillion-dollar business.
Consultants weigh in
Weight-loss surgeon Garth Daviswrites in his guide “Proteinaholic” that “‘eat extra protein’ often is the worst recommendation ‘consultants’ give to the general public.” Davis contends that almost all physicians within the U.S. have by no means truly examined a affected person with protein deficiency as a result of just by consuming an sufficient variety of every day energy we’re additionally most probably getting sufficient protein.
The truth is, People at the moment consume almost two times the Nationwide Academy of Medication’s really useful every day consumption of protein: 56 grams for males and 46 grams for ladies – the equal of two eggs, a half-cup of nuts and three ounces of meat – though optimum protein consumption might range relying on age and exercise degree.
Walter Willett, chairman of the division of vitamin on the Harvard T.H. Chan College of Public Well being, describes excessive protein consumption as “one of the fundamental processes that increase the risk of cancer.” Past these considerations, processed dietary supplements and protein bars are sometimes filled with energy and will comprise extra sugar than a sweet bar.
As acknowledged in The New York Instances, nonetheless, “the protein complement market is booming among the many younger and wholesome,” those that arguably want it least. The retail sales of protein products in the USA had been at $9 billion in 2020, up from about $6.6 billion in 2015.
Fat and carbohydrates have, together with sugar, taken turns being vilified for the reason that identification of macronutrients (fat, proteins and carbs) over a century in the past. As meals author Bee Wilson factors out, protein has managed to stay the “last macronutrient left standing.”
Why has protein endured because the supposed holy grail of vitamins, with many people wholeheartedly becoming a member of the search to devour ever-greater portions?
The news on protein merchandise
The historical past of producing and advertising protein-enriched merchandise goes again nearly so far as the invention of protein itself.
German chemist Justus von Liebig, one of many earliest to determine and research macronutrients, got here to treat protein “as the only true nutrient.” Liebig was additionally the primary to mass-produce and distribute a product related to protein within the 1860s, “Liebig’s Extract of Meat.”
Creator Gyorgy Scrinis writes that through “promoting and favorable publicity, the [Liebig’s Extract of Meat] firm achieved ‘appreciable success.’” Significantly for many who couldn’t afford to buy meat, the extract appeared an affordable and satiating substitute.
Protein consumption has remained a central part of dietary recommendation and advertising campaigns ever since, even amid recycled and recurring arguments over the optimum quantity of protein and whether or not plant or animal sources are greatest.
Across the time Liebig launched his extract firm, John Harvey Kellogg, a staunch vegetarian, got down to redefine traditional American meals at his well being sanitarium in Battle Creek, Michigan.
The Kellogg household invented flaked breakfast cereals, granola, nut butters and varied “nut meats,” which they produced, packaged, marketed and bought throughout the nation. Kellogg wrote numerous tracts denouncing meat-heavy diets and assuring readers that high-protein plant meals may simply change meat.
In an April 1910 subject of his periodical “Good Well being,” Kellogg posited that “Beans, peas, lentils and nuts afford an ample proportion of the protein components that are important for blood making and tissue constructing.”
Within the Seventies via the Nineties, protein merchandise remained seen however receded considerably with the dietary highlight firmly mounted on low-calorie, low-fat, sugar-free snack meals and drinks following the publication of studies linking sugar and saturated fats consumption to coronary heart illness. These many years gave us Slimfast and Weight-reduction plan Coke in addition to fat-free (and guilt-free) SnackWell’s cookies and Lay’s potato chips.
Complete diets adopted, every providing an array of protein drinks and bars. Robert Atkins first revealed his low-carb, high-protein “Dr. Atkins’ Diet Revolution” in 1982. It went on to grow to be one of many 50 best-selling books of all time by the early 2000s, regardless of a New England Journal of Medicine article in 2003 clearly recommending that “Longer and bigger research [were] required to find out the long-term security and efficacy of low-carbohydrate, high-protein, high-fat diets” similar to Atkins’.

The long-term pursuit of protein in hopes of attaining greater muscular tissues, smaller waists and fewer starvation pangs exhibits no signal of abating, and there has by no means been a dearth of these prepared to reap the benefits of the general public’s dietary objectives by handing out pointless recommendation or a brand new protein-packed product.
Ultimately, most individuals dwelling in high-income nations are consuming sufficient protein. Once we change meals with a protein bar or shake, we additionally threat lacking out on the wealthy sources of antioxidants, nutritional vitamins and lots of different advantages of actual meals.
