Nutrition

Nutrition is the process where the body takes in and uses food for growth, keeping your cells alive, and repairing them. It covers both the nutrients found in foods (e.g., proteins, carbohydrates, fats, vitamins, minerals) and how your body digests, absorbs, and uses them to maintain your health and bodily function.

The six essential nutrient categories are carbohydrates, proteins, fats, vitamins, minerals, and water. Macronutrients (carbohydrates, proteins, and fats) provide energy and are needed in larger amounts, while micronutrients (vitamins and minerals) are required in smaller quantities but are critical for your health.

"Superfood" is a marketing term, not a scientific one. It's typically used to describe nutrient-dense foods like berries, leafy greens, salmon, and nuts. While these foods are very healthy and nutritious, no single food provides all essential nutrients by itself. A varied, balanced diet is more important than focusing on "superfoods" alone.

Common signs include persistent fatigue, frequent infections, slow healing or recovery from illness, brittle hair and nails, unexplained weight changes, and difficulty concentrating. Deficiencies in certain nutrients have specific symptoms like anemia (low iron), muscle weakness (low protein), or bleeding gums (low vitamin C).

Essential daily nutrients include complete proteins (containing essential amino acids), healthy fats (containing essential fatty acids), some carbohydrates (for energy), fibre, 13 different vitamins, essential minerals and adequate water. Individual needs vary based on age, sex, activity level, and health status.
