-ENERGETIC FUNCTION: carbohydrates, proteins and fats provide energy needed by muscles and necessary to regulate body temperature.
-PLASTIC FUNCTION: proteins, fats and minerals provide substances that are necessary for tissues and cells renewal, body growth and development.
-REGULATORY FUNCTION: proteins, minerals, vitamins and water maintain vital body functions.
-PROTECTIVE FUNCTION: some kinds of proteins and vitamines help to develop and increase defense mechanisms.]]> 2017-02-05 15:53:38 UTC https://padlet.com/inglese123/2x1e0qlr6tav/wish/151665925 inglese123 https://padlet.com/inglese123/2x1e0qlr6tav/wish/151669926 About 2/3 of the human body is water. It is found in the blood and in the cytoplasm of our cells. Its main functions are:
-It dissolves and carries nutrients; 
-It regulates body temperature through perspiration.]]> 2017-02-05 16:45:19 UTC https://padlet.com/inglese123/2x1e0qlr6tav/wish/151669926 inglese123 https://padlet.com/inglese123/2x1e0qlr6tav/wish/151679632 Proteins are made from AMINO ACIDS . Our bodies can make most of the amido acids it needs, but there are 9 we can only get from food . These nine are called the essential amino acids . Proteins build and preparid tissues and fight off infections . Together with carbohydrates and fats , proteins are also our bodies' energy source. -ANIMAL PROTEINS:
such as meat , fish , eggs , milk and cheese , contain a good balance of all the amino acids that we need. 
-PLANT PROTEINS:
such as cereals and legumes , are lower in amino acids.]]> 2017-02-05 18:53:18 UTC https://padlet.com/inglese123/2x1e0qlr6tav/wish/151679632 inglese123 https://padlet.com/inglese123/2x1e0qlr6tav/wish/151679663 Fats , or lipids , are the nutrients that store energy. They are mostly found in the adipose tissue under our skin .
Fats can be of animal (cheese , butter, milk and fatty meat ) or plant source (olive oil and seed oil).]]> 2017-02-05 18:53:48 UTC https://padlet.com/inglese123/2x1e0qlr6tav/wish/151679663 inglese123 https://padlet.com/inglese123/2x1e0qlr6tav/wish/151679700  Carbohydrates are  grouped in:
-SUGARS:
such as glucose, fructose, saccharose and lactose;
-POLYSACCHARIDES:
like starches and cellulose.
Glucose is the most important sugar because its molecule is part of many other  carbohydrates.
One molecule of glucose plus one mulecule of fructose  form saccharose,  which is the kind of sugar  we use in our dishes.  
Starch is an essential nutrient.  It is found in bread, pasta ,legumes and potatoes.
Sugars are found in fruit and in sweet food ]]> 2017-02-05 18:54:20 UTC https://padlet.com/inglese123/2x1e0qlr6tav/wish/151679700 inglese123 https://padlet.com/inglese123/2x1e0qlr6tav/wish/151679707 Fibres cannot be digested because enzimes cannot break them down. Fibres  are very important because:
-they can prevent heart disease, diabetes, weight gain and some cancers;
-they improve digestive health.
Fibres can be found in all plant food, such as legumes, brown rice, wholemeal bread and pasta.

Our  body can only produce vitamins D and K, so we need to eat them. But the body only needs very small quantites of them.
-HYDROSOBLE VITAMINS, (group B and C) they dissolve in water and are not stored in our body.
-FAT-SOLUBLE VITAMINS , (A,D,E,K) are stored in fatty tissues.]]> 2017-02-05 18:54:50 UTC https://padlet.com/inglese123/2x1e0qlr6tav/wish/151679732 inglese123 https://padlet.com/inglese123/2x1e0qlr6tav/wish/151679747 Minerals are substances that are essential to our body. They have a plastic and regulatory functions.
Calcium, phosphorus and magnesium are the most important minerals for strong bones and teeth.]]> 2017-02-05 18:55:02 UTC https://padlet.com/inglese123/2x1e0qlr6tav/wish/151679747
