The Musculoskeletal System
Protein for Strong Muscles and Bones
The musculoskeletal system is actually two systems, the skeletal system (the bones that make up the ‘structure‘ of the body for movement and protection of organs) and the muscular system, consisting of all the muscles that allow us to move the body around, and to move things within the body itself (like efficient movement of food through the gut, and helping to shift lymph back to circulation for processing). Muscles are connected to bones by fibrous bundles of collagen tissue (tendons) and when muscles contract, they pull the bones and allow for human movement.
The importance of protein for the musculoskeletal system
Strong, healthy muscles and bones are critical for health and performance and protein is the king of nutrients for supporting the musculoskeletal system. All tissue is made up of protein structures that are, in turn, built from the amino acids that we get from proteins in foods. So, it is essential to get enough protein in order to thrive... and protein isn‘t just important for muscles. Bone is made up of protein structures that are ‘mineralised‘ (especially by calcium) and protein is equally important for strong, healthy bones!
Although most people get enough protein to survive, (1, 2) few actually get enough protein to support muscle and bone-loss as we age, (3) or to support optimal body composition (the fat-to-muscle ratio). Although ‘food comes first‘ and is the most important thing to try to get right for your health, because many people do not get sufficient protein from diet alone, protein powders offer a convenient solution, either before or after exercise, or as the base for a nutrient-dense smoothie.
Key benefits of protein for the muscles and bones:
- More lean mass and less fat mass (4-8)
- Increased strength and power (4)
- Reduced bone loss and increased bone-strength (5, 9, 10)
- Note: Increased protein also helps to improve
lipid profiles, increase immunity and reduce infection! (11-13)
How to use protein
- Take 1-2 serves of Nuzest Clean Lean Protein either before, or preferably after exercise
- For breakfast, or morning or afternoon snack: Blend 1-2 serves of Nuzest Clean Lean Protein with berries, veggies (like kale or spinach), healthy fats (nut butter, hemp seed or flaxseed oil, or MCT's or extra virgin olive oil), with water or your favourite plant milk for a ‘Carb-Appropriate‘ protein ‘meal in a glass‘!
