How Nutrients Work in the Body
Intro
- Nutrients are vital substances from food that keep our bodies functioning and help us stay healthy. These nutrients fall into two main groups: macronutrients and micronutrients.
Macronutrients
-
Macronutrients provide energy and are needed in larger amounts. This group includes carbohydrates, proteins, and fats.
-
Carbohydrates are the body’s main energy source. They are broken down into glucose, which is used to fuel cells throughout the body.
-
Proteins are essential for growth, repair, and maintenance of body tissues. They are also important in the production of enzymes, hormones, and antibodies.
-
Fats are a concentrated energy source and necessary for various bodily functions like vitamin absorption, hormone production, and insulation.
Micronutrients
-
Micronutrients are needed in smaller amounts, but are still crucial for our health. This group includes vitamins and minerals.
-
Vitamins, such as A, B, C, D, E, and K are necessary for various bodily functions like boosting the immune system, clotting blood, maintaining strong bones, and regulating cell function.
-
Minerals play a role in nerve function, muscle function, water balance, and structural systems such as bone structure. Key minerals include calcium, potassium, iron, and zinc.
Water
- Water accounts for 60-70% of a person’s body weight. It plays crucial roles like maintaining body temperature, transporting nutrients and oxygen, removing waste products, and acting as a lubricant and cushion for joints.
Fibre
- Fibre, though not digested, is essential for a healthy gut and prevention of diseases like diabetes and heart disease. It aids in digestion and helps with satiety (feeling full).
Conclusion
- Nutrients are essential to maintain health and prevent disease. Each nutrient group plays vital roles that contribute to overall wellbeing.
