Attention, body needs nutrition

What does the body need in order to do its work? (Food.) We also say that the body needs proper nutrition. What does the food provide? (Energy.) What foodsprovide energy? (Fruits, vegetables and grains because they give us sugar andstarch for energy.) We say that proper nutrition is the first principle of goodhealth. What does that mean? (Pause for student comments.)
Now let’s talk about what we did in the Mathematics Center. We worked withordinal numbers. Ordinal numbers tell us the position of an object. Look at theword “order”. Can you find part of that word in “ordinal”? Yes, “ord” is in
“order” and in “ordinal". That’s what ordinal numbers tell you — the order or theposition of objects. The ordinal numbers relate to the cardinal numbers. The cardinalnumbers are the numbers we are familiar with — they tell us how manythings are in a set or a group.
Now, why do you think that we say that nutrition is the first principle of goodhealth? Yes, proper nutrition is the first principle of good health because withoutnutrition the body cannot continue to live for a long time in good health. Whathappens when we are sick or do not have energy? Are we happy? Can we do thethings we want to do? No, nutrition is important, and so we say that it is the firstprinciple of good health.
When we studied about foods that give us energy, what experiments did youcomplete? What did we learn in our experiment using iodine? Yes, many foodsthat we eat contain starch, which is one food that gives us energy.
Nutritionists, people who study the kind and amount of food that people needto be in good health, measure the amount of food energy living organisms need byusing the unit of heat called a calorie. We use this unit to tell us how much foodwe need each day. If we know how much food we need each day, we will be ableto balance our meals and to avoid the weight we would gain if we ate too muchfat and too much starch.
But starch in our diet is not enough. What else do we need? What do fish,chicken, turkey and beef provide? (Those foods give us proteins that we need tobuild muscles and renew all the cells.)
As we saw from the activities on proper nutrition, all foods give us energy andhelp us build our bodies, but all foods give us more of one thing and less ofanother than the body needs. Very few foods give us everything the body needsall at the same time. That is why we need to eat balanced meals. The studentsconsider: Is fat necessary for the body? Is it an important food? How much fatshould we have in our daily diet?
You worked on an activity that required you to balance your body in order towalk from one end of the beam to the other. What did you have to do to stay inbalance? Yes, you couldn’t lean over too much on either side — you had to stayin the middle. What do you have to do in riding a bicycle? You can ride a bicycleonly if you balance on it. The same happens with your body and balanced meals.
You get energy and “building blocks” when you eat “balanced meals.” What doyou suppose “balanced” meals are? (Pause for student responses.) Yes, balancedmeals are meals that include foods from each of the five food groups. We don’twant to have too much of one thing and very little of another. (Display pictures offood from the Food Guide Pyramid.)
The Food Guide Pyramid is a guide, a suggestion, of the types and amountsof food that a person needs to be healthy. The Guide tells us that the group we 14 Unit 1 Good Healthshould select the most from is the Bread group, which includes oatmeal, Creamof Wheat, rice, spaghetti, for six to 11 servings every day. The next groups are the Vegetable group, which should include three to five servings every day, and the
Fruit group, which should include two to four servings each day. The Milk groupincludes cheese and yogurt, and should include two to three servings every day.
We should have the same number of servings per day from the Meat group,which includes beef, chicken, pinto beans, eggs and nuts. At the top of the pyramidand having the smallest triangle, are the fats, oils and sweets. This is notconsidered a food group because all foods contain fat and sugar. To be healthy,however, we should use fats, oils, and sugar barely, or with care. Fats and sugarare important, but they do not give energy and building blocks as do other foodsin a balanced diet.
We also said that one of the body needs is water. Do all living things need waterto live? We are going to look at the amount of water that living organisms need.
