What is Nutrition? (Definition)

Nutrition is the way in which living organisms receive and utilize food for growth, repair of tissues and overall health. To put it another way, it’s the way a food gives you energy and keeps your body working, alive, and healthy.

According to the World Health Organization (WHO), good nutrition is fundamental to health, and poor nutrition can lead to reduced immunity and increased susceptibility to disease, impaired physical and mental development, and reduced productivity.

Why is Nutrition Important?

Nutrition is important because it has a direct impact on:

1. – Growth and Development – Particularly for infants, children and adolescents.
2. – Energy Levels – A proper balance in your diet means you aren’t tired all day.
3. – Disease Prevention – A balanced diet minimizes your risk of becoming obese, developing diabetes, and other chronic diseases.
4. – Mental Health – Some nutrients (such as omega-3 fats and certain B vitamins) are also key contributors to your brain function and mental health.
5. -Longevity – Healthy eating habits extend life expectancy.

Types of Nutrition

Nutrition is classified into categories based on the source and function of the nutrient.

1. Macronutrients

These are the nutrients needed by the body in larger amounts:

• Carbohydrates – the primary source of energy.
• Proteins – build and repair tissue.
• Fats – provide long-term energy and support the health of cells.

2. Micronutrients

Micronutrients are generally required in small amounts, but are still a necessary component of our diet:

• Vitamins (A, B, C, D, E, K)
• Minerals (iron, calcium, potassium, magnesium)

3. Water

We often take for granted the importance of water, but it is essential to life! Water helps to transport nutrients, regulate body temperature, and purify the body.

Balanced Diet and Nutrition

A balanced diet consists of eating different amounts of nutrient in a day. Nutritionists’ recommendations state:

• Half of your plate should consist of fruits and vegetables.
• One quarter of your plate should consist of either whole grains (for example, brown rice, oats, or whole wheat) .
• One quarter of your plate should consist of protein sources like fish, chicken, beans, and lentils).
• You should also include healthy fats like avocados, olive oil, or nuts.
