Prof. Pistillo: Nutrition

Dear students,
here is some info about nutrition.

Nutrition

Nutrition provides the cells of an organism with food, in a form they can use. Organisms need food to be able to keep their bodies working properly. They also need food to be able to do certain things. Malnutrition can happen when a person doesn't eat the right amount of nutrients. They can get better by changing their diet so it has the right amount of nutrients.

The six main types of nutrient are carbohydrates, fats, minerals, protein, vitamins, and water. A macronutrient is a nutrient that needs to be eaten a lot. A micronutrient is needed in smaller amounts but it is still important. Carbohydrates are devided into 'complex carbohydrates' and 'simple carbohydrates'. Complex carbohydrates are more nutritious than simple carbohydrates. They take longer to digest. Because they stay in the stomach for longer they leave the person who has eaten them feeling fuller for longer. Protein is needed for building cells. It is found in meat, beans, and eggs. Protein is made of amino acids. Fat is found naturally in some foods. People often eat it in processed foods such as cakes and chocolate. It is high in energy. Omega 3 and omega 6 fats are needed by the body. There are saturated and unsaturated fats. It is recommended that people avoid the saturated type. It has been linked with heart disease.
Most people eat three meals a day. Eating every few hours keeps blood sugar stable.
