pääravintoaineiden

Pääravintoaineet are the macronutrients, which are essential components of a balanced diet. They provide the body with energy and are necessary for growth, repair, and various bodily functions. The three main macronutrients are carbohydrates, proteins, and fats.

Carbohydrates are the body's primary source of energy. They are broken down into glucose, which is used for immediate fuel or stored for later use. Carbohydrates can be found in foods like grains, fruits, vegetables, and dairy products.

Proteins are crucial for building and repairing tissues, producing enzymes and hormones, and supporting the immune system. They are made up of amino acids. Protein-rich foods include meat, fish, eggs, dairy, legumes, and nuts.

Fats are also a source of energy and play vital roles in nutrient absorption, hormone production, and protecting organs. There are different types of fats, including saturated, unsaturated, and trans fats. Healthy fats are found in foods like avocados, nuts, seeds, and olive oil.

Consuming a balanced intake of carbohydrates, proteins, and fats is essential for overall health and well-being. The recommended proportions of each macronutrient can vary depending on individual needs, activity levels, and health goals.
