Illnesses related to poor nutrition happen when your body does not get the right kind of food and nutrients it needs to be healthy. It's like your body needs certain things to work properly, just like a car needs gasoline and oil to run smoothly.
If you eat unhealthy foods over time, you might not get enough of the vitamins, minerals, and other nutrients you need to stay healthy. This can make you sick and cause different kinds of health problems.
For example, if you don’t get enough iron in your diet, you might feel tired all the time and not have enough energy to play or learn. This is called anemia.
If you don’t get enough vitamin C, your immune system (the part of your body that helps fight off germs and infections) might not work as well, and you might catch more colds and other illnesses.
If you eat too much unhealthy food, like candy, chips, and fast food, you might get too much sugar, salt, or unhealthy fats. This can cause problems like tooth decay, high blood pressure, and heart disease.
So, it's important to eat a healthy and balanced diet to keep your body healthy and strong. This means eating lots of fruits and vegetables, whole grains, lean proteins, and healthy fats.
