Nutrition and diseases
All over the world people suffer from illnesses that are caused by eating the wrong food or not having enough to eat.
In developing countries deficiency diseases arisewhen people do not get the right nutrients. Kwashiorkor is a disease that occurs if your body doesn’t get enough proteins. Marasmus occurs in young children who don’t get enough calories every day. They become weak, underweight and often die.
Diseases often occur if you suffer from a lack of vitamins. Not enough vitamin D, for example, may lead to bone illnesses.
In industrialized countries people often suffer from eating too much. Too much fat and cholesterol in your body can lead to heart diseases, obesity and cancer. High cholesterol levels may make your arteries narrow . The result may be high blood pressure , a heart attack or a stroke.
The lack of certain minerals may also lead to illnesses. Not enough iron in your food reduces the blood’s ability to make red blood cells, which are needed to transport oxygen through our body.
