When I think of nutrition, I do not think of nutrients in the first place. I think of delicious foods, like salad, watermelon, pineapple, grapes, cucumbers, tomatoes, mozzarella, all kinds of nuts, avocado, or a medium rare steak.
All kinds of foods contain nutrients, however in different proportions. If it comes to a healthy nutrition variety is the key. No matter what you preferred dish is, it wouldn´t be good to eat it every day, because then you couldn´t eat balanced and you would lack certain nutrients which are essential for your health and your own wellbeing.
The human body requires 7 major types of nutrients
In order to keep our metabolism going, the human body needs seven major types of nutrients: water, carbohydrates, fat, proteins, vitamins, minerals and fibre.
A common classification is to separate
- Macronutrients and
Macronutrients are nutrients we need in relatively large quantities, whereas micronutrients are nutrients we need in relatively small quantities.
- Carbohydrates – 4 kcal per gram
- Proteins – 4 kcal per gram
- Fats – 9 kcal per gram
According to another classification, macronutrients can be further split into energy macronutrients that provide energy and macronutrients that do not provide energy, like water and fibre.
