The actual definition of nutrition is providing or obtaining food that is necessary for health and growth, which supports us both physically and mentally.
It includes various processes and steps of food intake (ingestion), digestion, absorption, assimilation, biosynthesis, catabolism, and excretion (egestion).
Good nutrition means consumption of a balanced diet that provides us with all the above nutrients and many more, essential for body functions to maintain good health and boost our immune system.
There are two main types of nutrients:
- Macronutrients: Required for our bodies in large amounts. These include carbs, fats, proteins, and roughage.
- Micronutrients: Required in smaller amounts in our body. Micronutrients include minerals, vitamin C, vitamin D, vitamin A, etc, iron, zinc, potassium, and sodium.
The body will easily catch diseases, infections, fatigue, and poor performance, which eventually lead to poor health because of a lack of good nutrition.

Modern Diet Challenges
In recent times, diet habits around the world have changed dramatically. Fast food, processed meals, sugary snacks, and soft drinks are becoming more common, particularly in urban areas. While being convenient, these foods are often high in calories and low in nutrition.
Moreover, sedentary lifestyles combined with poor diets have contributed to rising levels of obesity, diabetes, and cardiovascular disease. The overuse of pesticides, food additives, and artificial ingredients has also raised concerns about food safety and long-term health effects.
The Importance of a Balanced Diet
A balanced diet is one that gives the body all the nutrients it needs to function correctly. To achieve this, individuals should eat:
- Eat a variety of foods to get a wide range of nutrients.
- Include plenty of fruits and vegetables, aiming for at least five servings per day.

- Practice portion control, avoiding overeating even healthy foods.
Planning meals around natural, whole foods and limiting processed items is one of the simplest and most effective ways to improve nutritional intake.

Conversely, diets high in processed foods, sugar, and unhealthy fats may contribute to mood swings, fatigue, and cognitive decline.
