True or False: Our body needs very little carbohydrate to stay healthy and happy.
Correct Answer
B. False
Explanation
Our body actually needs a significant amount of carbohydrates to stay healthy and happy. Carbohydrates are the main source of energy for our body and are essential for proper brain function and physical activity. They provide fuel for our muscles, organs, and brain, and help regulate blood sugar levels. Without enough carbohydrates, our body may experience fatigue, weakness, and difficulty concentrating. Therefore, the statement that our body needs very little carbohydrate is false.
2.
Carbohydrates are found in every food group except the following.
Correct Answer
D. Meats
Explanation
Carbohydrates are a macronutrient that provides energy to the body. They are found in grains, fruits, and vegetables, which are all part of a healthy diet. Meats, on the other hand, are a source of protein and do not contain significant amounts of carbohydrates. Therefore, meats are the only food group listed that does not contain carbohydrates.
3.
How much of the food we eat should be carbohydrates?
Correct Answer
C. Half
Explanation
Half of the food we eat should be carbohydrates. Carbohydrates are an essential macronutrient that provide the body with energy. They are found in foods such as grains, fruits, vegetables, and legumes. Including carbohydrates in our diet is important for maintaining proper bodily functions and fueling physical activity. However, it is also important to have a balanced diet that includes other macronutrients such as proteins and fats.
4.
True or False: Diets low in fiber increase the risk of heart disease and can elevate cholesterol.
Correct Answer
A. True
Explanation
Diets low in fiber increase the risk of heart disease and can elevate cholesterol. This is because fiber helps to lower cholesterol levels by binding to cholesterol in the digestive tract and preventing its absorption into the bloodstream. Additionally, fiber-rich diets promote healthy digestion and prevent constipation, which can contribute to heart disease. Therefore, a diet low in fiber can indeed increase the risk of heart disease and raise cholesterol levels.
5.
Simple carbohydrates are also called __________, while complex carbohydrates are also called starches.
Correct Answer
simple sugars, monosaccharide
starches
Explanation
Simple carbohydrates are also called simple sugars or monosaccharide because they consist of one or two sugar molecules that are easily broken down and absorbed by the body. On the other hand, complex carbohydrates are also called starches or polysaccharide because they are made up of long chains of sugar molecules that take longer to break down and provide a more sustained release of energy.
6.
Which pair does NOT belong?simple carbohydrate:oatmealsimple carbohydrate:bananacomplex carbohydrate:pastacomplex carbohydrate:corn
Correct Answer
A. Simple carbohydrate:oatmeal
Explanation
Oatmeal is a complex carbohydrate, not a simple carbohydrate. Simple carbohydrates are composed of one or two sugar molecules, while complex carbohydrates are made up of multiple sugar molecules. Oatmeal contains a type of complex carbohydrate called beta-glucan, which is a soluble fiber that provides various health benefits. Therefore, the pair "simple carbohydrate:oatmeal" does not belong because oatmeal is not a simple carbohydrate.
7.
True or False: Complex, starchy carbohydrates are the best choice to keep a healthy, happy body.
Correct Answer
B. False
Explanation
Complex, starchy carbohydrates are not necessarily the best choice to keep a healthy, happy body. While they can provide sustained energy and essential nutrients, an excessive intake of these carbohydrates can lead to weight gain and an increased risk of chronic diseases. It is important to have a balanced diet that includes a variety of nutrient-dense foods, including fruits, vegetables, lean proteins, and healthy fats.
8.
The average person should eat roughly _____ ounce(s) of carbohydrate every day.
Correct Answer
6
8
6-8
Explanation
The average person should eat roughly 6 ounces of carbohydrates every day. This is because carbohydrates are a major source of energy for the body and are needed for various bodily functions. However, the exact amount of carbohydrates needed can vary depending on factors such as age, sex, activity level, and overall health. It is recommended to consult with a healthcare professional or registered dietitian to determine the specific carbohydrate needs for an individual.
9.
Which type of carbohydrate is not digested by the human body but is essential for maintaining digestive health?
Correct Answer
B. Disaccharides
Explanation
Fiber is a type of carbohydrate that the human body cannot digest. It passes relatively intact through the digestive system and is classified into soluble and insoluble types. Soluble fiber dissolves in water and can help lower blood glucose and cholesterol levels, while insoluble fiber adds bulk to stool, promoting regular bowel movements and preventing constipation. Both types of fiber are crucial for maintaining a healthy digestive system.
10.
Which of the following foods is considered a complex carbohydrate?
Correct Answer
D. Brown rice
Explanation
Brown rice is a complex carbohydrate that contains longer chains of sugar molecules called polysaccharides. These complex carbohydrates are digested more slowly than simple carbohydrates, leading to a gradual release of glucose into the bloodstream, which provides sustained energy. In contrast, table sugar (sucrose) is a simple carbohydrate, white bread often contains refined carbohydrates, and apples primarily contain simple sugars like fructose but also some fiber.
