"Every cell in your body contains protein, a macronutrient made up of chains of amino acids, the so-called building blocks of life. It helps keep your body running smoothly, from aiding in digestion and regulating hormones, to speeding up exercise recovery and supplying blood with oxygen. Yet unlike fats and carbohydrates, the other two nutrients you need most, protein doesn't get stored in your body, explains Simin Levinson, M.S., a registered dietitian nutritionist and clinical professor in the College of Health Solutions at Arizona State University."
""Humans typically are protein-sparing, meaning that although we can use protein for energy-we have the metabolic pathways to do so-it is preferable that carbohydrates and fats are the predominant sources of fuel," Levinson tells Fortune. "That's because protein plays such a critical, functional role...and if that protein isn't provided, we start breaking down body tissues in order to produce those amino acids.""
"There's no denying the convenience of protein powder; you can prepare it in seconds, with no refrigeration or cooking involved. However, the supplement may not fuel your body with the variety of proteins that come from a balanced diet of whole foods"
Protein is an essential macronutrient present in every cell and composed of amino acid chains that support digestion, hormone regulation, exercise recovery, and oxygen transport in blood. The body does not store protein like fats or carbohydrates, so regular intake is needed to prevent tissue breakdown for amino acid supply. Humans tend to be protein-sparing, using carbohydrates and fats for fuel while preserving protein for critical functions. Protein supplements provide convenient, shelf-stable options, but they may lack the variety and nutritional completeness of whole food proteins. Global demand for protein supplements is growing, so evaluate quality and dietary needs before purchasing.
