What is nutrition?
Nutrition is the study of nutrients in food, how the body uses them, and the relationship between diet, health, and disease. Nutrients are the substances in food that our bodies need to function properly. They provide us with energy, build and repair tissues, and help to regulate our bodily functions.
The different types of nutrients
There are six main types of nutrients: carbohydrates, proteins, fats, vitamins, minerals, and water.
- Carbohydrates are our body’s main source of energy. They are found in foods such as bread, pasta, rice, fruits, and vegetables.
- Proteins are essential for building and repairing tissues. They are found in foods such as meat, fish, poultry, eggs, dairy products, and beans.
- Fats are also essential for our bodies, but they should be consumed in moderation. Fats provide us with energy, help to absorb vitamins and protect our organs. They are found in foods such as oils, nuts, seeds, and fatty fish.
- Vitamins are essential for many bodily functions, including growth, development, and immunity. They are found in a variety of foods, including fruits, vegetables, and whole grains.
- Minerals are also essential for our bodies. They help to build bones and teeth, regulate our heartbeat, and transport oxygen throughout the body. They are found in foods such as fruits, vegetables, whole grains, and dairy products.
- Water is essential for life. It makes up about 60% of our body weight and helps to transport nutrients throughout the body, regulate our body temperature, and remove waste products.
