12 Questions
______ are found most in starchy foods like bread, pasta, and potatoes as well as in fruits and vegetables and the main reason we need carbohydrates is as an energy source so they provide us with most of the energy that we need to carry out chemical reactions and move around
Carbohydrates
Main role is to provide energy just like carbohydrates but often they act as a longer term stores of energy because we can store lots of fat for use later they also do lots of other useful things though like keep us warm by insulating us and protecting our organs finally proteins are also found in a range of foods but particularly in nuts and seeds meat and fish and also legumes meaning things like lentils and beans you can think of proteins as building blocks so we need them to grow and to repair damaged tissue they can also be used for energy but only really in emergencies if we don't have enough carbohydrates or lipids
Proteins
Can be gained from foods like liver or leafy vegetables and you need it for good vision and to keep your skin and hair healthy then there's vitamin c which you can get from fruit and vegetables particularly citrus fruits like oranges and you need this to prevent yourself from getting the disease scurvy there's also vitamin d which is a weird one in that your body can actually make it itself using sunlight but you can also get it in foods like eggs and oily fish and its main purpose is to help you absorb calcium calcium itself though is actually an example of a mineral and is found in dairy products like milk as well as leafy vegetables you need calcium for strong bones and so if you don't eat enough calcium or you can't absorb it because you don't have enough vitamin d then it could lead to a condition like rickets where your bones can be deformed lastly we have iron which you get from red meat spinach and beans iron is a really important component of hemoglobin which remember helps your red blood cells transport oxygen around the body so if you don't get enough iron you can develop a condition called anemia where you can't transport as much

Foods like liver or leafy vegetables and you need it for good vision and to keep your skin and hair healthy then there's vitamin c which you can get from fruit and vegetables particularly citrus fruits like oranges and you need this to prevent yourself from getting the disease scurvy there's also vitamin d which is a weird one in that your body can actually make it itself using sunlight but you can also get it in foods like eggs and oily fish and its main purpose is to help you absorb calcium calcium itself though is actually an example of a mineral and is found in dairy products like milk as well as leafy vegetables you need calcium for strong bones and so if you don't eat enough calcium or you can't absorb it because you don't have enough vitamin d then it could lead to a condition like rickets where your bones can be deformed lastly we have iron which you get from red meat spinach and beans iron is a really important component of hemoglobin which remember helps your red blood cells transport oxygen around the body so if you don't get enough iron you can develop a condition called anemia where you can't transport as much
Vitamin A
Which is a weird one in that your body can actually make it itself using sunlight but you can also get it in foods like eggs and oily fish and its main purpose is to help you absorb calcium calcium itself though is actually an example of a mineral and is found in dairy products like milk as well as leafy vegetables you need calcium for strong bones and so if you don't eat enough calcium or you can't absorb it because you don't have enough vitamin d then it could lead to a condition like rickets where your bones can be deformed lastly we have iron which you get from red meat spinach and beans iron is a really important component of hemoglobin which remember helps your red blood cells transport oxygen around the body so if you don't get enough iron you can develop a condition called anemia where you can't transport as much
Vitamin D
Is a really important component of hemoglobin which remember helps your red blood cells transport oxygen around the body so if you don't get enough iron you can develop a condition called anemia where you can't transport as much
Iron
Your body can actually make it itself using sunlight but you can also get it in foods like eggs and oily fish and its main purpose is to help you absorb calcium calcium itself though is actually an example of a mineral and is found in dairy products like milk as well as leafy vegetables you need calcium for strong bones and so if you don't eat enough calcium or you can't absorb it because you don't have enough vitamin d then it could lead to a condition like rickets where your bones can be deformed lastly we have iron which you get from red meat spinach and beans
Vitamin C
Of hemoglobin which remember helps your red blood cells transport oxygen around the body so if you don't get enough iron you can develop a condition called anemia where you can't transport as much
Red meat
Can get from fruit and vegetables particularly citrus fruits like oranges and you need this to prevent yourself from getting the disease scurvy there's also vitamin d which is a weird one in that your body can actually make it itself using sunlight but you can also get it in foods like eggs and oily fish and its main purpose is to help you absorb calcium calcium itself though is actually an example of a mineral and is found in dairy products like milk as well as leafy vegetables you need calcium for strong bones and so if you don't eat enough calcium or you can't absorb it because you don't have enough vitamin d then it could lead to a condition like rickets where your bones can be deformed lastly we have iron which you get from red meat spinach and beans iron is a really important component of hemoglobin which remember helps your red blood cells transport oxygen around the body so if you don't get enough iron you can develop a condition called anemia where you can't transport as much
Vitamin B
Which remember helps your red blood cells transport oxygen around the body so if you don't get enough iron you can develop a condition called anemia where you can't transport as much
Spinach
Which remember helps your red blood cells transport oxygen around the body so if you don't get enough iron you can develop a condition called anemia where you can't transport as much
Beans
Your red blood cells transport oxygen around the body so if you don't get enough iron you can develop a condition called anemia where you can't transport as much

Study Notes
Macronutrients
- Carbohydrates are found in starchy foods like bread, pasta, and potatoes, as well as fruits and vegetables.
- The main role of carbohydrates is to provide energy for the body.
- Lipids are found in foods like nuts and seeds, meat, and fish, and also act as a longer-term store of energy.
- Proteins are found in foods like nuts and seeds, meat, and fish, and also legumes, and are used for growth and repair.
Vitamins
- Vitamin A is found in foods like liver and leafy vegetables, and is necessary for good vision and healthy skin and hair.
- Vitamin C is found in fruit and vegetables, particularly citrus fruits, and prevents scurvy.
- Vitamin D is found in foods like eggs and oily fish, and can also be produced by the body through sunlight exposure.
- Vitamin D helps the body absorb calcium, which is essential for strong bones.
Minerals
- Calcium is found in dairy products like milk and leafy vegetables, and is necessary for strong bones.
- Iron is found in red meat, spinach, and beans, and is a component of hemoglobin, which helps transport oxygen around the body.
- A lack of iron can lead to anemia, where the body can't transport enough oxygen.
- A lack of calcium or vitamin D can lead to rickets, where bones can become deformed.
