Nutrition is the process by which our body obtains the necessary nutrients for its proper functioning. These nutrients are found in the food we consume, and are divided into macronutrients (carbohydrates, proteins, and fats) and micronutrients (vitamins and minerals).

Nutrition is important for our health because a balanced and adequate diet provides us with the necessary nutrients to maintain a healthy body and prevent diseases. For example, a diet rich in fruits and vegetables can reduce the risk of heart disease and cancer, while a diet high in saturated fats can increase the risk of heart disease and diabetes.

In addition, good nutrition is essential to maintain a healthy immune system, which helps us to prevent illnesses and recover more quickly from them. It can also improve our mood and cognitive ability, allowing us to think more clearly and have more energy for our daily activities.

In summary, nutrition is essential for our overall health and well-being. Maintaining a balanced and adequate diet can help us prevent diseases, improve our quality of life, and enjoy a healthier life.

Although they are often used interchangeably, nutrition and food are different terms. Here we explain the differences:

  • Feding refers to the act of consuming food. It is a physiological process that involves ingesting food to obtain energy and nutrients.
  • Nutrition, on the other hand, is the process by which our body processes, absorbs, and utilizes the nutrients present in food to keep us healthy. Nutrition encompasses the digestion, absorption, and metabolism of nutrients and how they affect the body.

In other words, feeding is the act of eating, while nutrition is the process of how the body uses the nutrients present in food to maintain health.

Additionally, feeding focuses on the quantity and type of food consumed, while nutrition focuses on the quality of nutrients present in food and how they affect the health and well-being of the body.

It is important to understand the difference between nutrition and feeding in order to make informed and conscious decisions about what we eat and how it affects our health.


Maintaining a healthy and balanced diet may seem overwhelming at first, but with some simple and practical tips, you can easily achieve it. Here are some tips for maintaining a healthy and balanced diet:

  1. Incorporate a variety of foods into your diet, such as fruits, vegetables, whole grains, lean proteins, and healthy fats.

Here’s a list of foods and their suggested frequency to eat in a balanced diet:

  • Fruits and vegetables: It is recommended to eat at least 5 servings per day. For example, 1 serving of fruit is equivalent to one medium piece, while a serving of vegetables can be around 80 grams. You can consume different types of fruits and vegetables throughout the week.
  • Carbohydrates: It is recommended that carbohydrates make up approximately 50% of daily calories. A serving of complex carbohydrates such as brown rice, whole wheat pasta, or wholemeal bread would be approximately 1 cup. You can consume carbohydrates at each main meal.
  • Proteins: It is recommended to consume proteins at each meal. A serving of lean protein such as chicken, fish or legumes would be approximately 100 grams. You can consume proteins at each main meal and also as snacks.
  • Healthy fats: it is recommended to consume healthy fats such as olive oil, avocados, and nuts with moderation. A serving of healthy fats would be around 1 tablespoon of olive oil or 1/4 of an avocado. You can consume healthy fats in every main meal.
  • Fluids: it is recommended to drink at least 8 glasses of water a day and limit the consumption of sugary and alcoholic drinks. You can distribute the recommended amount of water throughout the day and consume sugary and alcoholic drinks with moderation.

It is important to remember that these are just general suggestions and nutritional needs may vary from person to person. If you have questions about your nutritional needs, it is recommended to consult a healthcare professional such as a dietitian for specific recommendations for your diet and lifestyle.
