What Is Nutritions?

Nutrition is the science of how food and drink affect our bodies. It is the study of nutrients, which are substances found in foods that our bodies use to grow, reproduce, and survive.

  • Carbohydrates are the body's main source of energy. They are found in foods such as bread, pasta, rice, fruits, and vegetables.
  • Proteins are needed to build and repair tissues. They are found in foods such as meat, poultry, fish, eggs, dairy products, legumes, and nuts.
  • Fats provide energy and help the body absorb certain vitamins. They are found in foods such as oils, butter, avocados, nuts, and seeds.
  • Vitamins are essential for many bodily functions, such as growth, immunity, and vision. They are found in a variety of foods, including fruits, vegetables, whole grains, and dairy products.
  • Minerals are also essential for many bodily functions, such as bone health, muscle function, and nerve function. They are found in a variety of foods, including fruits, vegetables, whole grains, and dairy products.
  • Water is essential for life and makes up about 60% of the adult body weight. It is important to drink plenty of water throughout the day.

Good nutrition means eating a variety of foods from all food groups to get all the nutrients your body needs. It is also important to eat in moderation and to limit processed foods, sugary drinks, and unhealthy fats.
