Protein, along with fat and carbohydrates, is key to keeping the body functioning properly. But people are likely eating too much of it, according to experts.
A Feb. 8 article in BBC Science Focus noted that, over the past decade, food companies have quadrupled the amount of high-protein products they sell worldwide—not because people need more protein, but because it’s a moneymaker. According to recent data from the Centers for Disease Control and Prevention, U.S. adults are eating an average of 2.9 ounces of protein per day—roughly 20% more than is recommended.
Walter Willett, professor of epidemiology and nutrition at Harvard T.H. Chan School of Public Health, was among experts quoted in the article. He said that while eating too much protein is unlikely to lead to serious health issues, it’s still important to consider its source. Animal protein is worse for health because it contains saturated fat and cholesterol, which can increase the risk of cardiovascular disease. Plant proteins are healthier, he said, because they contain more unsaturated fats, fiber, and healthy phytochemicals such as flavonoids.
“While there’s no definite link between overall protein intake and risk of death, greater intake of animal protein is associated with a higher risk of death,” he said. “And plant protein is associated with a lower risk.”
