Junk Food


  1. What is a junk food? Answer
  2. How does publicity influence people into buying junk food? Answer
  3. Can you give me a list of junk foods? Answer


We are students in Mexico and we have to make a project about how the junk food. We are thinking about junk food like a nutritional supplement affects the health and the knowledge of the older child and teens (between 12 to 15 years old). When we were looking for information we saw your website on the Internet. We think maybe you can help us with information and comments. We expect that you could help us and we will be glad if you answered these questions:

  1. What is junk food?
  2. What are the more common kinds of junk food?
  3. How does the junk food (like a nutritional supplement) affect the health and the knowledge of the old child and the teens?
  4. What is the relation between a good nutrition and the knowledge?
  5. What do you think about our project?


Thanks for all. We hope you could answer.

A nutritional supplement can be a vitamin or mineral pill or a beverage like Ensure that is taken by persons who don't get enough nutrition from the food you eat. I would not lump nutritional supplements with junk food. However in saying that, I realize that persons who want to build up their muscles like weight lifters will take nutritional supplements for which there is no scientific evidence like DHEA. Therefore, tread lightly when it comes to nutritional supplements. Perhaps you should go to your local pharmacy and talk to the pharmacist there about nutritional supplements. I would be surprised if 12 to 15 year olds were taking nutritional supplements other than boys who participate in a sport like football or wrestling.


Hi, we are students from Mexico, and we're making an investigation about junk food. We would be very glad if you could take a time to answer some questions for us, which are the following:

  1. Is junk food really junk (does it really affect or benefit human's health?
  2. Which are the characteristics of junk food?
  3. How does publicity influence people into buying junk food?
  4. What amount of junk food would be necessary for a person's daily diet, if it's necessary?


Beforehand, we want to thank you for your cooperation and we are looking forward to receiving an answer from you as soon as possible. We would also be glad if you could give us your full name, so we can make our information source reliable. Thank you very much.

  1. Junk food effects human health in that concentrated sources of sugar or fat can increase weight if the calories are more than the person needs.
  2. Junk food means that there is little redeeming nutritional value (small amounts of vitamins or minerals) in the food or that it is high in sugar or high in fat.
  3. Yes, advertising (publicity) does influence people's food purchases. But what kinds of foods are advertised? Watch your local television stations at the same time your friends are watching for 1 - 2 hours a day, for a week. What kinds of foods are advertised? Include the number of foods that are advertised in your report. How many high fat or high sugar foods were advertised? How many basic foods (milk, bread, fruit, vegetables, meat) were advertised during the same shows? In the US, it is usually high sugar or high fat foods. Milk, fruit and some cereal commercials are aired, but not as often as junk foods. Is it the same in Mexico?
  4. Junk food is not a necessary component of a person's diet so there is no minimum or maximum amount. What is necessary is milk, fruits, vegetables, bread, and meat.


I'm hearing a lot about junk food lately. No one has given a definition of what foods are junk. Can you give me a list of junk foods?

Junk food is a slang word for foods with limited nutritional value. Every person has their own list of foods that they call junk foods. I would include foods that are high in salt, sugar, fat or calories and low nutrient content.

Salted snack foods, candy, gum, most sweet desserts, fried fast food and carbonated beverages are some of the major junk foods. Generally, they offer little in terms of protein, vitamins or minerals and lots of calories from sugar or fat. The term "empty calories" reflects the lack of nutrients.

Rather than taking a radical approach and banning all but the simplest foods, judge each food based on the list of ingredients and Nutrition Facts label found on packages. When reading the list of ingredients, look for sugar, fat or salt as one of the first three ingredients. If any of these are listed that high in the ingredients, you can probably consider that food to be too high in sugar, fat or salt.

A look at the nutritional information on the label will list the number of calories per serving, grams of fat, sodium, cholesterol, fiber and sugar content. This nutritional information will make you more knowledgeable in selecting foods to reduce your nutritional health risk.

Calorie content of 300 calories per serving or less is considered to be all right, except whole meals unless you are following a weight loss diet. Be cautious though as to how large a serving size is. If 4 ounces of yogurt is a serving size and you eat an eight-ounce container, you have doubled the calorie content. Sometimes, the package serving size is not how little you serve yourself!

Now look at the number of grams of fat. For every five grams of fat in a serving of a food, you are eating the equivalent of one teaspoon of fat. So, if one serving of a food has 23 grams of fat in it, that serving has the equivalent of four and one-half teaspoons of fat. You should limit the fat content in foods you eat daily to 30% of your total calories. Don't try to lower your fat content to below 25%, since fat does play a vital role in carrying fat soluble vitamins and keeping you satisfied between meals.

Sodium content per serving should be 2300 milligrams or less per day. Some foods, like ham and other cured meats do have very high sodium content per serving. Limit these foods rather than eliminate them.

Cholesterol content should be 300 milligrams or less per day. It is easy to remember that 300 is the same as the number of calories per serving.

Fiber content will be listed in grams of dietary fiber. This amount will vary from product to product, but don't necessarily shop for only the highest numbers you can find. Any amount of dietary fiber above two grams per serving is good. Foods with five grams of fiber or more are considered high fiber foods.

Sugar content is usually listed on cold cereal packages. A rule of thumb to follow is four grams of sugar equals one teaspoon of sugar. Limit sugars amounts in cereals to four grams, but if the cereal has fruit in it, relax the sugar content to eight grams per serving. Fruits usually contain about 60% fructose and 40% sucrose. If you were to eliminate all sugar, you would be eliminating fruits, which are a valuable source of nutrients and soluble fiber.

If you want to cut down on junk food, cut down your intake of salt, sugar, fat and refined foods. Choose your calories by the nutrient company they keep.
