vitamins and minerals(??)

role of carbohydrates

energy source: helps us carry out chemical reactions and move around

role of lipids

provide energy (longer term stores of energy), keep us warm by insulating us, and protect our organs

role of proteins

we need them to grow, and to repair damaged tissue. can be used for energy but only when we don’t have enough carbohydrates or lipids

difference between vitamins and minerals

vitamins are organic molecules, minerals are inorganic

role of vitamin A

good vision, healthy hair, healthy skin

role of vitamin C

prevents us from getting scurvy (vitamin C deficiency - joint/muscle/leg pain, swollen bleeding gums, red/blue spots on skin [usually legs or feet])

role of vitamin D

helps you absorb calcium

role of calcium

need it for strong bones. don’t eat enough/can’t absorb it (vit D definitely) you get rickets

role of iron

important component of haemoglobin which helps red blood cells transport oxygen around the body. iron deficiency can lead to anaemia making you feel tired (lack of oxygen transported to tissues)

role of fibre

helps food move through our intestines properly, stops us from getting diarrhoea or constipation

role of water

we need it for chemical reactions in the body and most of our body is made of water. continuously losing water by breathing, sweating, or urinating - needs constant replacement
