Dear Kids!
Do you have anyone in your family with a disease to nutrition? If yes, name this disease.
Lots of people in our country are starting to realize that the kind of food we put into our bodies are very important. Physicians, dentists, scientists, teachers, parents are all realizing that there is a big need for all of us to eat foods that will help us to stay healthy. Everyone is talking about the importance of good nutrition. One important reason for all this interest in food is that there are so many people who have diseases that are called nutrition related diseases. Some people are eating foods with too much sugar, salt, fat and some of us are simply eating too much food. By overeating, health problems may occur. There are the following diseases that are closely connected to nutrition.
DIABETS
TOOTH DECAY
HIGH BLOOD PRESSURE
HEART ATTACS
CANCER
If someone in your family has one of these diseases, you run a greater risk of getting it yourself. This does not mean that you will certainly get one of them .But you must remember that there are some diseases connected with food. So, pay attention to what you eat and how much you eat.
Here are some definitions of nutrition related diseases.
OBESITY - the clinical term obesity is given to the presence of excess body weight 15 % or more above the ideal weight.
DIABETES MELLITUS - Is a chronic disease which interferes with the body’s ability to utilize sugar as a fuel every cell in your body needs sugar for making energy for walking, running eating or relaxing. However, sugar itself cannot get into your body’s cells. It needs help. This help is provided by a complex chemical called INSULIN. IT is produced by a small organ situated near the stomach called the PANCREAS. Diabetes occurs when the pancreas does not produce enough insulin to permit the body to utilize sugar.
There are two types of diabetes: insulin dependent and non insulin dependent. The insulin dependent is controlled by diet and insulin. Non-insulin dependent diabetes usually affects adults and those who are obese.
HIGH BLOOD PRESSURE - is the force exerted by the bloodstream against the walls of arteries.
Normally each time our heart beats 60 – 70. The blood flows to parts of the body, such as liver, kidney or brain and returns to the heart throu the veins. The blood pressure can rise during periods of excitement, nervousness, or exercise or it can become low when you sleep. Normal blood pressure varies depending on age. For adults it is 140/90, for children it is 105/60.
ARTERIOSCLEROSIS - hardening of the arteries can occur if blood pressure is not controlled and some of the fat that normally circulates in our body is pushed more rapidly into the walls of the arteries.Placque accumulates in the arteries, like rust on the inside of the pipe.
HEART ATTACK - If the arteries that supply blood to the heart become clogged with fatty material, the blood flow to portions of heart is slowed. When one of the vessels is completely closed off, there is a temporary stoppage of all blood flow to a part of the heart. Portions of the heart muscle are damaged. We say that a heart attack has occurred.
CANCER - occurs when normal cell reproduction ceases. Cancer cell change and are malformed, imperfect, incapable to normal cell life.
Research indicates that there may be a greater relationship between cancer and dietary.
