Western society has lengthy been obsessive about protein. However for a minimum of a decade, a lot of the media has been asking if this obsession is actually that essential—and in line with specialists, the overall consensus isn’t any, it’s not.
“It’s not a nutrient that’s of grave concern,” Andrea N. Giancoli, MPH, RD informed The Washington Publish in 2014. Two years later, sports activities nutritionist Robbie Clark informed HuffPost that the majority Australians are consuming “way more protein than they really want.” And in 2023, medicinal chef Dale Pinnock informed Males’s Well being that the fixation on protein was an instance of “bro science.”

None of that is to say that protein just isn’t necessary. It very a lot is. Protein is a necessary macronutrient—it helps with muscle progress and restore, enzyme operate, hormone regulation, immune system assist, vitality ranges, and extra. It’s simply that the typical individual doubtless doesn’t must obsess over it fairly as a lot as society is telling them to. And by society, proper now, we principally imply social media. On TikTok, greater than 1 million posts characteristic the hashtag #highprotein, whereas simply #protein exceeds 3.1 million posts.
To determine how a lot protein we actually want (and what occurs if we pack in an excessive amount of), we spoke to specialists to get the lowdown on this much-hyped macronutrient. Plus, vegetation or animals—does it matter the place you get it from?
How a lot protein do people actually need?
The really useful every day protein consumption for adults varies—the steering adjustments, relying on elements like exercise stage (an athlete wants considerably extra, for instance), weight, and intercourse. However basically, for many wholesome folks, the advice is to eat round 0.8 grams of protein per kilogram of physique weight per day.
Proper now, nevertheless, most adults within the US are literally exceeding this. Actually, analysis suggests they’re consuming double the quantity of protein neded. “Athletes and people who find themselves extra bodily lively may have extra protein, however for most individuals, exceeding 2 grams per kilogram is probably going extreme,” Wan Na Chun, MPH, RD, CPT, and proprietor of the meals weblog One Pot Wellness, informed VegNews.

She added that “focusing closely on protein might crowd out different important vitamins out of your weight-reduction plan, reminiscent of fiber, carbohydrates, and wholesome fat.” None of those get as a lot consideration as protein.
The hashtags #carbohydrates, #healthyfats, and #fiber are all dwarfed by the protein hashtags. And but, they’re simply as necessary. Fiber is linked with sustaining digestive well being, intestine well being, and decreasing ldl cholesterol, for instance, and carbohydrates are important vitality sources that additionally assist mind well being and performance. Wholesome fat are additionally necessary for vitality ranges, in addition to coronary heart well being, hormone manufacturing, vitamin absorption, and rather more.
What occurs in case you eat an excessive amount of protein?
Firstly, it’s unlikely the typical individual would eat a lot protein that it might trigger them main issues. “Protein is a macronutrient, that means it contributes to your whole caloric consumption, and thus extra consumption might end in undesired weight achieve,” explains Derek Lipton MS, RD, CSSD, CSCC, founding father of Full Circle Sports activities Diet. “Nonetheless, that is extraordinarily uncommon since protein could be very filling, which frequently results in much less general consumption.”
These with kidney issues, nevertheless, must be aware. “The kidneys filter out protein within the physique, and in case you overload them with protein, this might result in the kidneys being broken slowly over time,” says Michelle Saari MSc, RD, of the EHealth venture. “That is particularly regarding for anybody who’s predisposed to kidney issues.”

Nonetheless, even in case you don’t have points together with your kidneys, you can nonetheless discover some in poor health results from consuming extra protein than your physique wants. For some folks, it might result in nausea, constipation, diarrhea, and bloating. However not consuming sufficient protein also can result in points, therefore why it’s necessary to stay to the rules.
“Chronically low protein consumption can result in muscle loss, weak spot, and fatigue. This may make on a regular basis actions tougher and hinder restoration from accidents,” says Chun.
Which is best, animal protein or plant protein?
Most individuals who comply with a diversified and balanced weight-reduction plan are getting sufficient protein—yep, even vegans. Plant-based sources of protein embody tofu, peas, beans, lentils, chickpeas, nuts, and seeds. However animal merchandise are, in fact, filled with protein, too.
“Each plant-based sources like beans and animal-based sources like meat have their very own set of distinctive vitamins which can be helpful for the physique,” notes Chun. “Animal proteins are ‘full,’ that means they comprise all 9 important amino acids, and are thus more practical for muscle progress and restore,” says Lipton. “Nonetheless, plant-based proteins, reminiscent of beans, might be simply as efficient so long as a number of sources are consumed with a purpose to [obtain] the entire amino acids; for instance, consuming beans with rice.”
“Whereas the general protein consumption may be adequate, it is rather frequent for folks to rely closely on animal sources for protein. This may result in potential points like consuming extra saturated fats and neglecting different important vitamins like fiber discovered extra readily in plant-based protein sources,” Chun explains.
However whereas there’s no denying that animal merchandise may give us protein, additionally they typically include main downsides. Crimson meats, for instance, are filled with protein (one steak accommodates round 25 grams), however additionally they comprise excessive ranges of saturated fats. The latter can elevate blood levels of cholesterol, and when consumed typically, might result in a better danger of coronary heart illness. Analysis suggests consuming an excessive amount of purple meat might improve the danger of sort 2 diabetes by 62 %, and it might additionally elevate most cancers danger, too.
The World Well being Group classifies purple meat merchandise as a Group 2 carcinogen, whereas processed meats (like sausages, bacon, and so forth) are categorized as Group 1—the identical class as smoking.
Then again, a rising physique of analysis has linked plant-based complete meals with a decreased danger of power illness. In 2023, researchers checked out 20 randomized medical trials and located {that a} plant-based whole-foods weight-reduction plan might assist lower the danger of coronary heart illness. One other research that very same yr linked consuming extra plant-based protein with a decrease danger of kidney illness, and additional analysis instructed {that a} plant-based weight-reduction plan might assist reverse sort 2 diabetes.
“The prevalence of diabetes is rising, as is recognition within the healthcare group that weight-reduction plan as the first intervention can obtain lasting remission in people with sort 2 diabetes,” Gunadhar Panigrahi, MD, the research’s first creator, stated in an announcement on the time.
Past Meat
However whereas complete meals, plant-based sources are extensively considered by many specialists as the perfect sources of protein for our well being, analysis has additionally instructed that vegan protein-packed meat alternate options—like these from Past Meat and Unattainable Meals—are higher for us than conventional meat merchandise. Actually, a 2023 Stanford research instructed that incorporating a mean of two servings of plant-based meat alternate options into your weight-reduction plan might result in a discount in sure cardiovascular danger elements.
“Discover [protein sources] that you just love consuming and discover inventive methods to cook dinner them,” Saari stated.
So, in the case of protein consumption, the winner, in our view, is seemingly clear: don’t sweat it an excessive amount of, and follow vegetation for essentially the most half. So long as you’re consuming all kinds of complete meals, the important vitamins (together with all-important fiber, carbohydrates, and wholesome fat) ought to maintain themselves—and certain with out the heightened illness danger both.
One remaining notice: be sure you make room for pleasure in your plate, too. “The most effective protein supply will all the time be the meals that you just take pleasure in and can really eat all through the day,” says Saari.
