Hello, everyone! Thank you for joining me! Do you know what affects which foods you eat? Follow me and I will tell you about food in your life, and what affects your food choices.
In this lecture I will tell you what the terms “nutrients” and “nutrition” mean. I will also tell you about the differences between hunger and appetite. And most importantly, you will learn the issues that affect which foods you choose to eat.
Nutrients are the substances in food that your body needs to function properly to grow, to repair itself, and to supply you with energy. You get nutrients from the different foods that you eat, and those nutrients affect all aspects of your life. Nutrients can affect how you look, how you feel, how you act, and how you grow.
Hunger is your body’s physical need for food. It is the natural drive that protects you from starvation. When you are hungry, the walls of your stomach contract, which stimulates nerves. This tells your brain that your body needs food. Once you eat, the nerve endings are no longer stimulated and you feel full.
Appetite is different from hunger, because it is a desire to eat, not a need . You learn your appetite based on what you are exposed to in your environment, including your culture, family and friends, the media you are exposed to, and your lifestyle.
You may make your food choices based on culture, including the cultural celebrations and ethnic foods you were raised with. You may also have religious beliefs that dictate which foods you can eat and when. Age is also a factor, because people tend to eat similar food as their peers.
As you were growing up in your family, you probably had certain foods that you ate together. You probably also had celebrations, like religious holidays or Thanksgiving. All of the foods you grew up eating shaped which foods you will like or dislike in your life. You may also have tried new foods at friends’ houses that you liked or disliked, and you may have continued to eat it. As you can see in the cartoon below, children can also affect which foods parents want to eat.
You may see advertisements on television, on the radio, or in magazines for different brands of food. Advertisers try to influence you using their ads to get you to try their product and, if you like it, to keep buying it. Make sure you think about the ads that you see, because they may persuade you to buy the product, and most likely they are misleading. In the next slide you will see a commercial for a canned spaghetti meal. The commercial is targeted at young children, and you can see you they might be persuaded to want to try it.
Because people have busy lives, they try to find foods that are fast and easy to make, and that don’t cost very much. Unfortunately, some foods, like TV dinners, are filled with sodium and are not very healthy. It is important to eat healthy foods, even if it may take a little longer to cook them. Your emotions have a big impact on what you eat. You might eat more or less that usual when you are bored, stressed, frustrated, depressed, upset, or tense. Eating too much can lead to overeating, which is unhealthy. But eating too little can cause a nutrient deficiency, which is also bad for you. Try to be mindful of what you eat to be sure that you are not overeating or skipping meals.
It is important for you to eat healthy foods so that you can avoid undesirable health conditions, like high blood pressure, high cholesterol, and obesity. Unfortunately, many people can’t distinguish between being hungry and having an appetite, so they end up overeating. Eating habits contribute to the top six leading causes of death in the United States, like heart disease, stroke, and cancer.
Nutrition is the process by which the body takes in and uses food. The nutrients in food help you to grow and develop. They give you energy and help you to look and feel your best. As an adolescent, it is more important than ever for you to get proper nutrition so you can grow up healthy and strong.
As you can see in this chart, people’s eating habits have changed a lot from 1970 to the present. We are now eating more of everything except for healthy, calcium rich dairy products. We are eating a lot more of the unhealthy foods, like fats and sugars. It is not all bad news, though, because people are eating more of the healthier foods, too, like fruits and vegetables.
Today you learned that hunger is a physical need for food and appetite is a desire to eat. You should try to distinguish between them in your own life. Now you also know that proper nutrition comes from eating enough of the right nutrients, and those nutrients help you to grow and develop. There are many factors that affect your food choices, and you should be mindful of them so that you can choose healthier foods.
For more information about nutrition and healthy food choices, you can go to the United States Government’s official nutrition website, at nutrition.gov, or you can visit the United States Department of Agriculture’s food and nutrition information center website. Thank you for learning with me, and I hope you did learn a lot!
