nutrients - the part of foodstuffs that feed your body and make it strong
what is a disease and describe the 3 different types of diseases
a disease is any condition that causes person pain, dysfunction, distress, social problems / death.
- Infectious diseases that are transmitted between people such as tuberculosis (TB), HIV and AIDS.
- Lifestyle diseases such as diabetes and obesity. these diseases have to do with how people live.
- Neurological diseases affect the body’s nervous system, such as epilepsy.
what are the different factors that cause disease (3)
number of factors that increase person’s risk of developing disease. unhealthy lifestyle + environment can cause poor health. if we understand what causes diseases, we can make choices what’ll protect us and keep us healthy. illnesses can be caused by:
- Social factors: How we live affects our health. e.g. - not enough exercise, an unhealthy diet, substance abuse and stress all cause illnesses.
- Environmental factors: e.g., unclean water, unhygienic living conditions, pollution.
- Economic factors: healthy foods and clean environments cost money.
What are the 3 main things that cause diseases (not the factors)
1 - Use of alcohol and tobacco
people who abuse alcohol can seriously damage bodies. too much alcohol stops liver working properly. when livers don’t work properly, we are less able to fight off diseases. it’s easier to get infections, + wounds don’t heal well. alcohol can damage other important organs too, such as heart + brain.
smoking tobacco also poisons our bodies. nicotine + other poisonous chemicals damage lungs + heart each time we light up. it’s more difficult for blood to move around in body, so smokers may feel more tired than those who don’t.
2 - Poor eating habits
in our modern world, we eat too much fast and processed food. these foods high in fats + sugars and don’t contain any nutrients. eating unhealthy food can lead to becoming overweight, which can cause high blood pressure and increase the risk of heart disease, diabetes and strokes.
3 - Physical inactivity
exercise important part staying healthy. helps you keep a healthy weight. it reduces your risk of heart disease and some types of cancer. it relieves tension + stress, which helps you fight off illness.
modern people do lot of sitting, even when we work. we often watch TV rather than play games, and use transport to move around. unfortunately, more physically inactive we are, more likely we are to get ill.

HIV and AIDS
HIV virus which affects the person’s immune system; eventually the person develops AIDS, a fatal disease. the most common ways of spreading HIV are are through sexual contact, sharing needles / from infected mothers to their babies during birth and breastfeeding. once person is infected with HIV, virus stays in body rest of their lives. are drugs that can help to control virus. it is possible live healthy, happy life when you are HIV-positive.
Antiretroviral drugs are main form treatment for HIV. they don’t cure HIV, but can people getting sick for many years. people who are HIV-positive should also:
- eat healthy, balanced diet
- avoid alcohol cigarettes
- avoid exposure to infectious diseases

describe HIV and AIDS even more such as how do you get it what is it and which body fluids contain it.
What is HIV
H - Human - this particular virus can only infect humans
I - Immunodeficiency - HIV weakens your immune system by destroying important cells that fight disease and infection. a a “deficient” immune system can’t protect you.
V - Virus - a virus can only reproduce itself by taking over a cell in the body of its host.
Human Immunodeficiency Virus is a lot like other viruses, including those that cause the “flu” or the common cold. but there is an important difference - over time, your immune system can clear most viruses out of your body. that isn’t the case with HIV - the human immune system can’t seem to get rid of it. Scientists are still trying to figure out why.
we know that HIV can hide for long periods of time in the cells of your body and that it attacks key part your immune system - your T-cells / CD4 cells. your body has to leave these cells to fight infections and disease, but HIV invades them, uses them to make more copies itself, and then destroys them.
over time HIV can destroy so many of your CD4 cells that your body can’t fight infections and diseases anymore. when that happens, HIV infection can lead to AIDS.
What is AIDS
A - Acquired - AIDS is not something that you inherit from your parents. you acquire AIDS after birth.
I - Immuno - Your body’s immune system includes all the organs and cells that work to fight off infection or disease.
D - Deficiency - you get AIDS when your immune system is “deficient,” or it isn’t working the way it should.
S - Syndrome - a syndrome is a collection of symptoms and signs of a disease. AIDS is a syndrome, rather than a single disease, because it is a complex illness with a wide range of complications and symptoms.
Acquired Immunodeficiency Syndrome is the final stage of HIV infection. people at this stage of HIV disease have badly damaged immune systems, which put them at risk for opportunistic infections (OIs).
you will be diagnosed with AIDS if you have had one or more specific OIs, certain cancers, / very low numbers of CD4 cells. if you have AIDS, you will need medical intervention and treatment to prevent death.
How do you get HIV
HIV is found in specific body fluids. is any of those fluids enter your body, you can become infected with HIV.
Which body fluids contain HIV
HIV lives and reproduces in blood and other body fluids. we know that following fluids contain high levels of HIV:
- blood
- semen
- breast milk
other body fluids and waste products - like faeces, nasal fluid, saliva, sweat, tears, urine / vomit - don’t contain enough HIV to infect you, unless they have blood mixed in them and you have significant and direct contact with them.
How is HIV transmitted through body fluids
- during pregnancy, childbirth / breastfeeding: babies have constant contact with their mother’s body fluids-including amniotic fluid and blood-throughout pregnancy and childbirth. after birth, infants can get HIV from drinking infected breast milk.
- as a result of injection drug use: injecting drugs puts you in contact with blood-your own and others, if you share needles and “works”. needles / drugs that are contaminated with HIV-infected blood can deliver the virus directly into your body.
- as a result of occupational exposure: healthcare workers have greatest risk for this type of HIV transmission. if you work in a healthcare setting, you can come into contact with infected blood or other fluids through needle sticks / cuts. a few healthcare workers have been infected when body fluids splashed into their eyes, mouth, / into an open sore / cut.
- as a result of a blood transfusion with infected blood or an organ transplant from an infected donor: screening requirements make both of these forms of HIV transmission very rare.
- during sexual contact: if your partners has HIV, those body fluids can deliver the virus into your bloodstream through microscopic breaks / rips in the delicate linings of your private areas and mouth. rips in these areas are very common and mostly unnoticeable. HIV can also enter through open sores, like those caused by herpes / syphilis, if infected body fluids get in them.
you need to know that it is much easier to get HIV (or to give it to someone else), if you have a sexually transmitted disease (STD).
