Nutrient

Essential substances that the body needs to function properly. They include macronutrients (carbohydrates, proteins, fats) and micronutrients (vitamins and minerals).
A nutrient is a substance that the body needs for growth, metabolism, and overall health. Nutrients are essential for various bodily functions, and they can be classified into two main categories:
1. Macronutrients
These are needed in larger amounts and provide energy:
- Carbohydrates: The body’s primary energy source.
- Proteins: Important for building and repairing tissues, as well as producing enzymes and hormones.
- Fats: Essential for energy storage, protecting organs, and helping absorb certain vitamins.
2. Micronutrients
These are needed in smaller amounts but are crucial for health:
- Vitamins: Organic compounds that support various bodily functions (e.g., vitamin C for immune function).
- Minerals: Inorganic elements that play roles in processes like bone health (e.g., calcium) and oxygen transport (e.g., iron).
Water
Though not typically categorized with nutrients, water is essential for life, helping with digestion, circulation, and temperature regulation.
Overall, a balanced diet containing a variety of nutrients is vital for maintaining good health.
Deficiency
A lack of a specific nutrient in the body, which can lead to various health issues. For example, vitamin D deficiency can cause bone problems.
Medicine
Substances used to diagnose, treat, or prevent disease. Some medicines can help manage deficiencies (e.g., vitamin supplements).
Vitamin
Organic compounds crucial for normal metabolism and health. Vitamins are categorized into water-soluble (like vitamin C) and fat-soluble (like vitamins A, D, E, and K).
Importance of Vitamins
Vitamins support various bodily functions, including:
- Metabolism: Helping convert food into energy.
- Immune Function: Supporting the body’s defense against illnesses.
- Bone Health: Contributing to bone strength and integrity.
- Nervous System: Supporting brain function and nerve health.
Calcium
A vital mineral important for bone health, muscle function, and nerve transmission. Deficiency can lead to osteoporosis and other bone disorders.
Calcium is essential for bone health, muscle function, and nerve transmission. Here are some excellent sources of calcium:
