Nutrition Chapter 1 Test: MCQ Quiz!

The correct answer is "All of the above" because nutrient functions include providing energy (calories), materials for building body parts, and regulating body processes. Nutrients such as carbohydrates, fats, and proteins provide energy for the body, while vitamins and minerals contribute to the building and maintenance of body tissues. Additionally, nutrients play a crucial role in regulating various body processes such as metabolism, hormone production, and immune function. Therefore, all of these functions are encompassed by the term "nutrient functions."

The correct answer is "The study of nutrients in food and in the body". This answer accurately describes nutrition as the field that examines the nutrients present in food and their effects on the human body. It encompasses the study of various components found in food and their role in maintaining health and preventing diseases. Additionally, nutrition also investigates how the body processes and utilizes these nutrients for growth, energy, and overall well-being.

Essential nutrients are substances that our body needs to function properly but cannot produce on its own, so we must obtain them from our diet. These nutrients are necessary for growth, development, and maintenance of our overall health. They include vitamins, minerals, proteins, carbohydrates, and fats. Since essential nutrients are required for our body's functioning and cannot be synthesized by the body, they must be obtained from natural food sources.

Energy is defined as the capacity or ability to do work. Work is the transfer of energy from one object to another, or the transformation of energy from one form to another. Therefore, the correct answer is "work" because it accurately describes the relationship between energy and the ability to perform a task or exert a force on an object.

The given answer is correct because it states that alcohol contains 9 calories per gram. This is higher than the calorie content of carbs and protein, which both contain 4 calories per gram. Fat also contains 9 calories per gram, so the statement that alcohol contains 7 calories per gram is incorrect.

Essential nutrients are substances that the body cannot produce or cannot produce in adequate quantities. These nutrients must be obtained from food sources. They have specific biological functions in the body, and their absence can lead to a decline in bodily functions. However, when these nutrients are restored, normal bodily functions can be regained. Therefore, all of the given statements accurately describe essential nutrients.

Nutrients are broken down in the body through various metabolic processes, such as digestion and cellular respiration, to produce energy. The term "yield" means to produce or provide, which accurately describes the process of breaking down nutrients to generate energy. Therefore, "yield" is the correct answer in this context.

A calorie is a unit of measurement used to quantify the amount of energy that food provides when consumed. It represents the energy required to raise the temperature of one gram of water by one degree Celsius. Calories are commonly used to determine the energy content of food and beverages, and they play a crucial role in understanding and managing one's diet and overall energy balance.

The answer provided is 70,000. This number represents the estimated average number of meals eaten in a lifetime. It is important to note that this number can vary depending on factors such as individual eating habits, cultural practices, and lifespan. However, 70,000 is a reasonable estimate for the average person.

Fortified nutrients refer to the addition of one or more nutrients to a food product. This process is done to enhance the nutritional value of the food and provide additional essential nutrients that may be lacking. Fortification is commonly done with vitamins, minerals, or other beneficial substances to address specific nutrient deficiencies or improve the overall nutritional profile of the food. By adding these nutrients, the fortified food can help individuals meet their dietary requirements and promote better health.

Carbohydrates, lipids, proteins, vitamins, minerals, and water are the six classes of nutrients. These nutrients are essential for the body to function properly and maintain good health. Carbohydrates provide energy, lipids (fats) are a concentrated source of energy and help with insulation and protection of organs, proteins are important for growth and repair of tissues, vitamins are necessary for various metabolic processes, minerals are needed for proper body functions, and water is essential for hydration and maintaining bodily functions.

Phytochemicals are substances found in plant foods that may have health promoting properties. These compounds are naturally occurring and can provide various benefits to human health. They are known for their antioxidant, anti-inflammatory, and anti-cancer properties. Phytochemicals are abundant in fruits, vegetables, whole grains, legumes, herbs, and spices. Consuming a diet rich in phytochemicals has been associated with a reduced risk of chronic diseases such as heart disease, cancer, and diabetes. These substances can help boost the immune system, protect against oxidative stress, reduce inflammation, and support overall well-being.

Energy is defined as the amount of heat required to increase the temperature of 1 gram of water by 1 degree Celsius. This definition is based on the concept of specific heat, which is the amount of heat energy required to raise the temperature of a given substance by a certain amount. In this case, the specific heat of water is being used to measure energy.

Nutrients are chemicals found in foods that are essential for human growth and function. They provide the body with energy, help in the development and repair of tissues, and support various physiological processes. Nutrients include carbohydrates, proteins, fats, vitamins, minerals, and water. Without these essential chemicals, the body would not be able to perform its normal functions and maintain good health.
