  • THE FOOD WHEEL

    NUTRIENTS:

    GlucidsGlucids

    Proteins

    Fat

    Vitamins

    Mineral salts

    Water

    Nutrients give us energy, permit us growing and make our body to run properly..

  • NUTRIENTS

  • GLUCIDS, CARBOHYDRATES

    They give us energy.

    TYPES:

    Simple glucids: Sugar, sweet flavour. Lactose from milk. They give us energy very quickly.

    Complex: starch (almidn). They give us energy for a long time.

    BREAD, PASTA, CEREALS, SUGAR, POTATOES, LEGUMES, MILK

  • Try to join each food with the kind of glucid it has:

    SIMPLE GLUCIDS:

    SUGAR

    COMPLEX GLUCIDS

  • LIPIDS, FATS

    They give us energy for a long time and formed structures in our body.

    TYPES:

    Fats: saturated and insaturated fats. Saturated (most of them from animals) are not good in big ammounts. Poliinsaturated (most of them from plants) are the best fats we can eat.

    Lipids that formed our cells membranes.

  • PROTEINS

    THEY ARE USED TO BUILD AND REPAIR STRUCTURES IN OUR BODY.

    They transport oxygen in our blood.

    They formed our hair and They formed our hair and muscles.

    They are formed by little mollecules called aminoacids. There aminoacids that are essential to our body that we cannot make them, so we have to eat with the food. The others aminoacids can be sinthetized by our organism.

    CHEESE, MEAT, FISH, MILK, LEGUMES.

  • VITAMINS

    THEY ARE USED TO CONTROL SEVERAL FUNCTIONS.

    THE Y ARE IMPORTANT FOR THE CORRECT RUNNING OF OUR BODY.TYPES:

    Fat soluble vitamins: they

    We need them in small ammounts, but their lack cause a lot of illnesses.

    They are destroyed by heat or by air, so we can find vitamins in raw and fresh food.

    Fat soluble vitamins: they accumulate in the liver.vitamins A, D, E and K.

    Water soluble vitamins: they do not accumulate in any organ. Vitamins B and C.

    FRUITS, VEGETABLES

  • MINERAL SALTS

    THEY FORME OUR BONES, THEY REGULATE

    IMPORTANT FUNCTIONS IN OUR BODY

    WATER

    ALL FOOD CONTAINS MINERAL SALTS

    WATER

    IT DISSOLVES NUTRIENTS, WASTE, IT REGULATES TEMPERATURE AND IT TRANSPORTS SUBSTANCES ALONG OUR BODY.

    MILK, VEGETABLES, FRUITS

  • HUMAN ENERGY REQUIREMENTS

    Nutrients give us energy to practise sports, to grow and to allow our body to run properly.

  • Las necesidades energticas de una persona dependen de la edad, peso, estatura y actividad dependen de la edad, peso, estatura y actividad fsica.

    El metabolismo basal es la energa mnima que necesita nuestro organismo para llevar a cabo los procesos vitales: respirar, bombear sangre.
