Carbohydrates, proteins, and lipids are considered ________.
- A.
Micronutrients
- B.
Macronutrients
- C.
Antioxidants
- D.
Free radicals
Correct Answer
B. MacronutrientsExplanation
Carbohydrates, proteins, and lipids are considered macronutrients because they are the three main types of nutrients that provide energy to the body. Macronutrients are required in large amounts and are essential for growth, development, and overall functioning of the body. They are the primary source of calories and play a crucial role in providing fuel for various bodily processes such as metabolism, muscle building, and cell repair. Micronutrients, on the other hand, refer to vitamins and minerals that are required in smaller quantities for proper functioning of the body. Antioxidants and free radicals are not directly related to the classification of nutrients.Rate this question:

Which of the following is an inorganic nutrient?
- A.
Minerals
- B.
Vitamins
- C.
Carbohydrates
- D.
Lipids
Correct Answer
A. MineralsExplanation
Minerals are inorganic nutrients because they are derived from non-living sources such as rocks and soil. They are essential for various bodily functions and are required in small amounts. Examples of minerals include calcium, iron, potassium, and zinc. They play a crucial role in maintaining healthy bones, teeth, and muscles, regulating fluid balance, and supporting the immune system. Unlike minerals, vitamins are organic compounds derived from living organisms, while carbohydrates and lipids are organic macronutrients that provide energy.Rate this question:

Your body is approximately _______% water
- A.
30
- B.
45
- C.
60
- D.

Correct Answer
C. 60Explanation
The correct answer is 60. This is because the human body is made up of approximately 60% water. Water is essential for various bodily functions such as maintaining body temperature, transporting nutrients, and lubricating joints. It also plays a crucial role in digestion, metabolism, and waste removal. Therefore, it is important to stay hydrated to ensure the proper functioning of the body.Rate this question:

Cultural influences encompass a wide range of aspects, including religious practices, traditional cuisines, and customs surrounding food preparation and consumption. Therefore, the influence on food choices most closely related to religion, beliefs, and traditions is cultural.Rate this question:

- A.
Placebo
- B.
Clinical trial
- C.

- D.
Epidemiological
Correct Answer
D. EpidemiologicalExplanation
Epidemiological research studies compare disease rates among different population groups and aim to identify any related conditions or behaviors. This type of study focuses on understanding the distribution and determinants of health and disease in specific populations. It helps in identifying risk factors, patterns of disease occurrence, and potential interventions to prevent or control diseases at a population level.Rate this question:

A chemical whose absence from the diet for a long time results in specific changes in health is________ .
- A.
Nutrient
- B.
Water
- C.
An enzyme
- D.
An antioxidant
Correct Answer
A. NutrientExplanation
A nutrient is a substance that is essential for the body's growth, development, and maintenance. When a nutrient is absent from the diet for a long time, it can lead to specific changes in health because the body relies on these substances to function properly. Nutrients provide energy, support metabolism, and are involved in various physiological processes. Therefore, the absence of a nutrient can cause deficiencies or imbalances in the body, resulting in specific health issues.Rate this question:

General functions of the six classes of nutrients include all of the following except:
- A.
Regulation of body processes
- B.
Contribute to body structure
- C.
Provide energy
- D.
Add flavor to food
Correct Answer
D. Add flavor to foodExplanation
The six classes of nutrients, which include carbohydrates, proteins, fats, vitamins, minerals, and water, have various functions in the body. They regulate body processes, contribute to body structure, and provide energy. However, adding flavor to food is not a function of these nutrients. Flavor in food is primarily determined by other components such as spices, herbs, and seasonings. Nutrients play a crucial role in maintaining overall health and well-being, but they do not directly contribute to the flavor of food.Rate this question:

D
Correct Answer
D. DExplanation
A fat-soluble vitamin is a type of vitamin that can dissolve in fats and oils. Vitamin D is a fat-soluble vitamin that is essential for the absorption of calcium and phosphorus in the body. It plays a crucial role in maintaining bone health, as well as supporting immune function and cell growth. Unlike water-soluble vitamins, which are not stored in the body and need to be replenished regularly, fat-soluble vitamins can be stored in the liver and fatty tissues for longer periods of time.Rate this question:

Epidemioligical
Correct Answer
D. EpidemioligicalExplanation
Epidemiological research studies compare disease rates among different population groups and aim to identify conditions and behaviors that may be related to the disease. This type of study focuses on understanding patterns of diseases in specific populations and determining risk factors that contribute to the development of the disease. By analyzing data from large groups of people, epidemiological studies provide valuable insights into the distribution and determinants of diseases, which can help inform public health interventions and policies.Rate this question:

Essential nutrients_______________ .
- A.
Are made by the body
- B.
Can only be supplied adequately with dietary supplements
- C.
Must be obtained through diet
- D.
Consist of over 75 different types of nutrients
Correct Answer
C. Must be obtained through dietExplanation
Essential nutrients are substances that the body requires for normal functioning but cannot produce on its own. Therefore, they must be obtained through diet. This means that individuals need to consume a variety of foods that provide essential nutrients such as vitamins, minerals, proteins, carbohydrates, and fats. Without obtaining these nutrients through the diet, the body may not be able to perform essential functions and may be at risk of developing deficiencies or health problems.Rate this question:

In a study of how vitamin E may reduce the risk of cadiovascular disease, one group was given a placebo, and the other group was given vitamin E supplements. The group that recieved the placebo was the _________ .
- A.
Control group
- B.
Experimental group
- C.
Double-blind group
- D.
Hypothetical group
Correct Answer
A. Control groupExplanation
In a study, it is important to have a control group to compare the effects of the treatment being tested. The control group is not given the actual treatment (in this case, vitamin E supplements) and instead receives a placebo. By comparing the outcomes of the control group with the experimental group (those receiving the actual treatment), researchers can determine if the treatment has any significant effects. Therefore, the control group serves as a baseline for comparison and helps to establish the effectiveness of the treatment being studied.Rate this question:

Which nutrient contains the most calories per gram?
- A.
Vitamins
- B.
Lipids
- C.
Carbohydrates
- D.
Protein
Correct Answer
B. LipidsExplanation
Lipids contain the most calories per gram compared to other nutrients. While vitamins, carbohydrates, and proteins provide energy, lipids have a higher caloric content. This is because lipids are made up of fatty acids, which have more carbon and hydrogen atoms than other nutrients. This higher carbon-hydrogen ratio leads to a higher energy density, resulting in more calories per gram. Therefore, lipids are the nutrient that contains the most calories per gram.Rate this question:

By the time we reach adulthood, our food preferences and intake are largely influenced by a core group of about 100 basic items. These items make up approximately 75% of the food we consume. This suggests that while we may have a wide variety of food choices available to us, we tend to rely on a relatively small number of staple foods for the majority of our dietary needs.Rate this question:
