A person who has a healthy diet, that is, a balanced diet from meats, vegetables, eggs and milk, you need not worry about the lack of these chemical ingredients. Some are present in greater quantities, for example, in green vegetables, meat on the other, but all are common in most foods. Malnutrition in the Northeast Brazilian All Brazilians have a balanced diet? This interferes with the body's chemistry? What diseases can cause a lack of these chemicals? ACTIVITY Do a search in your school and find out if there are people with problems of growth. What consequences it brings to health? Nowadays, it is known that the chemicals in our body are distributed in the following percentages: Oxygen - 65% - constituent of water and organic molecules (containing carbon and hydrogen, produced by a living system). It is necessary for cellular respiration, which produces adenosine triphosphate (ATP), a chemical very rich in energy. Carbon - 18.5% - found throughout the organic molecule. Hydrogen - 9.5% - Formation of water, all foods and most organic molecules. Nitrogen - 3.2% - component of all proteins and nucleic acids: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).

Izvor: Brasilindy media.org/image2006 To je malo, ali presudno za pravilno funkcioniranje tijela. Nedostatak željeza uzrokuje osoba simptome stanja koje se naziva anemija. Osoba koja ima zdrave prehrane, to jest, uravnotežene prehrane od mesa, povrća, jaja i mlijeko, ne morate brinuti o nedostatku tih kemijskih sastojaka. Neki su prisutni u većim količinama, primjerice, u zelenom povrću, mesu, s druge strane, ali svi su uobičajene u većini hrane. Pothranjenost na sjeveroistoku Brazilac Svi Brazilci imaju uravnotežene prehrane? To ometa tijela kemije? Koje bolesti mogu uzrokovati nedostatak tih kemikalija? AKTIVNOST Ne traži u svojoj školi i saznati ako postoje ljudi s problemima rasta. Kakve posljedice koje donosi zdravlje? Danas, to je poznato da su kemikalije u našem tijelu raspoređena u sljedećim postocima: Kisik - 65% - sastavni dio vode i organskih molekula (koji sadrže ugljik i vodik, produced by živom sustavu). To je neophodno za stanično disanje, koja proizvodi adenozin trifosfata (ATP), kemijski vrlo bogata energijom. Ugljik - 18,5% - naći diljem organske molekule. Vodik - 9,5% - Formiranje vode, sve namirnice i većinu organskih molekula. Dušik - 3,2% - sastavni dio svih proteina i nukleinskih kiselina: deoksiribonukleinske (DNA) i ribonukleinska kiselina (RNK). materije i njezine prirode
