Protein has become a buzzword in the food industry, with many products now touting high protein content. But why is everyone so obsessed with protein? According to Joan Salge Blake, a clinical professor of nutrition at Boston University’s Sargent College of Health & Rehabilitation Sciences, this trend may be here to stay.
As an essential macronutrient, protein plays a critical role in the structure and function of the body’s tissues and organs. It’s found in muscle, bone, skin, hair, and many other body parts. While protein has always been important for a balanced diet, its recent emphasis coincides with the introduction of specific weight-loss medications.
For those taking semaglutide weight-loss drugs, which can drastically reduce appetite, protein intake is especially crucial to help manage hunger and nausea. However, for most people without specific health or diet needs, getting enough protein isn’t a major concern.
According to the National Academy of Medicine, adults need at least 7 grams of protein per day, depending on their body weight. Eating enough protein helps muscles rebuild and increases satiety. However, Salge Blake warns that an intense focus on one macronutrient can displace a balanced diet.
“A balanced diet is relatively boring,” she says, “but it’s essential.” This means eating a variety of foods, including nutritious fruits and vegetables. As the protein obsession may stick around, it’s crucial to remember that a well-rounded diet is still the best approach for overall health.
