Choosing Food Wisely

You eat for several reasons: to meet you nutritional needs, to satisfy your appetite, and to supply your body with energy. Hunger is a feeling of physical discomfort that is caused by your body’s need for nutrients. Appetite is a desire for food that is based on emotional and other factors rather than nutritional need for food that is based on emotional and other factors rather than nutritional need.

Your body’s nutritional needs are related to your basal metabolic rate. Basal metabolic rate (BMR) is the rate at which you use energy when your body is at rest. Your level of activity also affects your calorie.

factors influencing food choices
Factors influencing food choices

Your food choices are based on many factors. These factors include personal preferences, cultural background, time and convenience, friends, and the media.

When choosing foods, it is important to read and evaluate the information on the food label. The information includes nutrition facts, nutrient and health claims, Daily Values, and freshness date. The United States Food and Drug Administration (FDA) requires that food labels list specific nutrition facts about a food. These facts include calorie and nutrient content and health claims that can be printed on a food label.


Nutritionists have developed a tool called Daily Values to help people make good food choices. Daily Values are recommendations that specify the amounts of certain nutrients that the average person should obtain each year. Food labels list the percent Daily Values for each nutrient in the food. Labels on prepared foods also include open dates that give consumers an idea of how long the food will be fresh and safe to eat. Three kinds of dates are the “sell-by” date, the “best-if-used-by” date, and the “do-not-use-after” date.

Safely Managing Your Weight

A person’s weight is determined by various factors, including heredity, level of activity, and body composition. Based on your family history, you may have a natural tendency toward a certain weight. Your activity level influences your weight; the more active you are, the more calories you burn. Body composition is a measure of how much body fat you have, as compared to muscle and bone. Sex and age affect your body composition.

One simple way to assess whether your weight falls within a healthy range is to calculate your body mass index. Body mass index (BMI) is a ratio of your weight to your height.

The number of people in the United States who are overweight is increasing. Being overweight can lead to serious health problems, including heart disease and diabetes. Overweight describes a person who is heavier than the standard for the person’s height. Obesity (oh bee sih tee) refers specifically to adults who have a BMI of 30 of higher.

health risks
Health Risks

The health risks associated with being overweight include high blood pressure, excess cholesterol in the blood, excess glucose in the blood, heart disease, stroke, and certain cancers. Managing your weight can help prevent these health risks.

Underweight describe a person who is lighter than the standard for the person’s height. Being underweight can be linked to health problems such as anemia, heart irregularities, and trouble regulating body temperature.

Sensible weight management involves avoiding dangerous diet plans, choosing nutritionally balanced meals and snacks, and getting regular exercise. Fad diets, diet aids, and fasting are unsafe ways to lose of gain weight. A fad diet is a popular diet that may help a person lose of gain weight without proper regard for nutrition and other health issues. Fad diets can place the dieter’s health at risk.

weight loss strategies
Weight Loss Strategies

Some strategies for safe and sensible weight loss include recognizing your eating patterns, planning helpful weight-loss strategies, and exercise. Strategies for sensible and safe weight gain include increasing your calorie intake by choosing nutrient-dense foods and exercising regularly.

2. Teresa leads a busy life-she’s on Student Counsel, sings in the school chorus, and has a lead in the school play. She doesn’t have time to exercise or eat right, although she knows she should. What can she do?

3. Hector is tall and thin, like the rest of his family. He wants to put on some weight and hopes to make the football team next year. Hectors family ha never been concerned about health eating, but now, Hector thinks he should be.

4. Sophia and her best friends have challenged each other to a weight loss competition. Sophia is planning to go on the new “low-carb” diet she has heard a lot of people talking about. What advise would you give Sophia?

Dear Advice Line,

Writing Write a response to this teen to help solve the problem.

nutrition for individual needs
Nutrition for Individual Needs

Diabetes is a disease with dietary requirements that can help people manage their condition. Poor nutritional habits and being overweight increases the risk of type 2 diabetes. Type 2 diabetes is a condition in which the blood contains high levels of glucose. Eating balanced meals on a regular schedule, monitoring carbohydrate intake, and controlling weight are important for managing diabetes.

A vegetarian is a person who does not eat meat. A vegan is a vegetarian who does not eat only food that comes from an animal source. Because vegetarians exclude certain foods from their diets, they need to plan their food choices carefully to avoid potential health risks. Benefits of a vegetarian diet can include a lower BMI and a lower risk of heart disease and type 2 diabetes. Vegetarians must plan their diets carefully to make sure that they get all the amino acids their bodies need to build proteins as well as adequate supplies of vitamins and minerals.


People with food sensitivities, which include food allergies and food intolerances, may require special diets. A food allergy is a response by the immune system to the proteins in certain foods. Symptoms of food allergies appear suddenly and can be severe. People with allergies to certain foods should avoid those foods. A food intolerance is an inability to digest a particular food or food additives. Symptoms of food intolerance can be harder to recognize than symptoms of allergies.

Athletes need a well-balanced diet with the recommended amounts of carbohydrates, fats, and proteins. Athletes need to consume extra calories to fuel their higher level of physical activity. They should also drink plenty of fluids, preferably water, to replace fluids lost in perspiration during physical activity. Carbohydrate loading is the practice of greatly increasing carbohydrate intake and decreasing exercise on the days immediately before competition. This is not necessary for the average athlete.
