Protein has become a buzzword in health and fitness circles, and Caitlin Mellendorf, a Nutrition Educator with the University of Illinois Extension, is emphasizing its critical role in our diets. 

Protein, a vital nutrient made up of amino acids, serves as the body’s building blocks, supporting everything from muscle repair to immune function—and Mellendorf is helping people understand how to choose the best sources - noting there are plenty of ways to get protein, from traditional meats to newer options like protein drinks and dairy. 

Mellendorf explains that protein is essential at all ages, helping young people build strong bones and muscles while allowing older adults to maintain their strength and mass.

Protein powders are gaining popularity, but Mellendorf advises against depending on them alone.

According to Mellendorf, solid proteins often feel more satisfying, while liquid protein takes longer for your body to recognize as sufficient.
