Powering up with protein
Protein, often referred to as the building block of life, plays a pivotal role in maintaining the human body's intricate functions. From hormone support to muscle synthesis, protein is an essential nutrient that deserves our attention.
The Role of Protein
Proteins are large molecules comprised of amino acids, which serve as the foundation for tissues, enzymes, hormones, and antibodies. These multifaceted molecules are involved in almost every aspect of bodily function, acting as catalysts for chemical reactions and aiding in cellular communication.
Tissue Building: Protein is crucial for tissue repair and growth, making it essential for maintaining healthy skin, hair, nails, and muscles.
Enzymes and Hormones: Many enzymes are proteins, facilitating essential biochemical reactions. Additionally, hormones, such as insulin and growth hormone, are proteins that play a central role in regulating bodily processes.
Immune Support: Antibodies are specialised proteins that help our immune system defend against infections and diseases.
Protein for Hormone Support
Hormones are messengers that orchestrate various bodily functions, including metabolism, growth, and reproduction. Protein intake is vital for hormone production and balance. For instance:
Insulin: This hormone regulates blood sugar levels and is made up of protein. Adequate protein intake can help support the production and function of insulin, promoting stable blood sugar levels.
Thyroid Hormones: The thyroid gland produces hormones critical for metabolism and energy regulation. Protein provides the necessary amino acids for the synthesis of these hormones, aiding in maintaining a healthy metabolism.
Sex Hormones: Hormones like oestrogen, progesterone, and testosterone are essential for reproductive health and overall well-being. Consuming enough protein supports the production and maintenance of these hormones.
Protein for Muscle Synthesis
Protein and muscles share a unique relationship. When we engage in physical activity, particularly resistance training, our muscles undergo stress and small tears. Protein steps in to repair and rebuild these damaged muscle fibres, making them stronger and more resilient.
Muscle Repair: Protein provides the amino acids necessary for muscle repair after exercise, leading to improved muscle function and reduced soreness.
Muscle Growth: For individuals aiming to build muscle mass, protein consumption is vital. A positive protein balance is necessary to support muscle growth, alongside proper training and rest.
30g protein
Studies have shown that aiming for 30g of protein at breakfast is key for metabolic health, womenโs hormones, and insulin resistance.
Under 30g, you are still getting valuable amino acids and blood sugar balancing effects, however, if you consume 30g or more, you are stimulating muscle mass. 30g of protein is the threshold that stimulates muscle protein synthesis (MPS), where we create new and protect existing muscle tissue.
Sources of Protein
Now that we understand the significance of protein, let's explore some excellent sources to incorporate into our diets:
Animal Sources: Lean meats like chicken, turkey, fish, and eggs are complete sources of protein, meaning they contain all the essential amino acids our bodies need.
Plant-Based Sources: Legumes (e.g., lentils, chickpeas, beans), tofu, tempeh, quinoa, and edamame are fantastic protein-rich options for vegetarians and vegans.
Nuts and Seeds: Almonds, chia seeds, pumpkin seeds, and peanuts offer a healthy dose of protein along with essential fats.
Dairy Products: Greek yogurt, cottage cheese, and milk are excellent sources of protein and calcium.
Protein serves as a fundamental pillar of our health, supporting hormone regulation and muscle development. From aiding in tissue repair to facilitating hormone synthesis, protein plays an indispensable role in countless bodily functions. By incorporating a diverse range of protein sources into our diets, we can ensure our bodies receive the essential amino acids they need to thrive.
