Why is protein important anyway? Most of us know that protein helps build muscle, but it does so much more.
1️⃣ Protein breaks down into amino acids, which compose essentially every cell in the body. Protein helps transport molecules through the body. 1
2️⃣ Protein also digests more slowly than carbohydrates, so it helps us to feel satiated for longer periods of time. Protein can help keep blood sugar levels stable. Sudden drops in blood sugar can lead to decreased cognitive function and attention span. 2
3️⃣ Protein is important because of its role in making hormones and enzymes. This is so important for everyone, but especially for teens whose hormones can use support and help with regulating. 3
4️⃣ Low protein intake has been linked with higher cortisol levels, aka your stress hormone. When cortisol stays high, your nervous system can’t shift out of “fight-or-flight.” 3
5️⃣ Protein helps with aging. Bone and muscle loss as well as loss of strength and mobility, all increase with age but protein helps delay this age related deterioration. 4
