The Primer on Protein, Part 3: Mental Health

Part 3 of the “Primer on Protein” series emphasizes the crucial role of protein in supporting mental health alongside physical health. Protein-rich foods like meat, fish, eggs, and dairy provide essential amino acids, such as tryptophan and tyrosine, which are vital for producing key neurotransmitters like serotonin and dopamine. Serotonin promotes a positive mood and resilience, while dopamine drives motivation and focus. A lack of these amino acids can negatively impact mental well-being, contributing to conditions like depression and anxiety. CrossFit’s nutrition prescription prioritizes high-quality protein intake to support both physical and mental health.

Primer on Protein, Part 2: Bones

In Part 2 of the “Primer on Protein” series, the focus shifts to the role of dietary protein in bone health. CrossFit’s nutrition prescription highlights the importance of animal foods (meat, fish, eggs, etc.), which provide high-quality protein. Protein-rich foods, especially those cooked on the bone or containing skin, provide key amino acids necessary for bone health. Diets lacking these foods can lead to lower bone density and increased fracture risk, while high protein intake, especially in older adults, is associated with stronger bones and reduced risk of osteoporosis.

The Primer on Protein, Part 1: What Is Food For

In “World Class Fitness in 100 Words,” the first prescription for achieving fitness is focused on food, not exercise, highlighting the importance of nutrition. While food provides energy, it also offers crucial building blocks for the body, like amino acids, which form proteins essential for brain, muscle, and tissue function. This series explores how dietary protein supports muscle health, which is vital for longevity and disease prevention.
