Nutrition is the cornerstone of good health. In today’s fast-paced world, it’s easy to overlook the importance of a balanced diet. Yet, what we eat directly impacts how we feel, how we perform, and how we age.

What is Nutrition?
Nutrition refers to the intake of food in relation to the body’s dietary needs. Good nutrition – an adequate, well-balanced diet – combined with regular physical activity, is a cornerstone of good health. Poor nutrition can lead to reduced immunity, increased susceptibility to disease, impaired physical and mental development, and reduced productivity.
Essential Nutrients and Their Role
1. Carbohydrates
Carbs are the body’s main source of energy. They fuel your brain, kidneys, heart muscles, and central nervous system. Examples: Whole grains, fruits, and vegetables.
2. Proteins
Proteins help build and repair tissues. They’re important for building muscles and producing enzymes and hormones. Examples: Eggs, legumes, dairy, and meat.
3. Fats
Healthy fats provide long-lasting energy and support cell growth. They also help protect your organs and keep your body warm. Examples: Avocados, nuts, seeds, and olive oil.
4. Vitamins
Vitamins play a key role in vision, skin health, and immune function. Examples include Vitamin A (carrots), Vitamin C (oranges), and Vitamin D (sunlight exposure).
5. Minerals
Minerals like calcium, potassium, and magnesium are vital for strong bones, nerve function, and maintaining a healthy heartbeat.
6. Water
Water is crucial for digestion, nutrient transport, and maintaining body temperature. Aim for at least 8 glasses a day.
