Question 1

Which of the following statements is FALSE?&#10;A)Phytochemicals are nutrients necessary for sustaining health and life.&#10;B)Phytochemicals protect plants from insects and microbes.&#10;C)Phytochemicals have been shown to reduce the risk of cardiovascular disease and cataracts.&#10;D)Phytochemicals are naturally occurring compounds found in plants.

Accepted Answer

Phytochemicals are not considered essential nutrients like vitamins and minerals, but they do play a role in maintaining health and preventing diseases. However, they are not necessary for sustaining life.

Question 2

Research has found that the health-promoting properties of phytochemicals are primarily due to their antioxidant activity.

Accepted Answer

False

Question 3

An RDA for phytochemicals has not been established.

Accepted Answer

An RDA for phytochemicals has not yet been established. Phytochemicals are plant-based substances that have potential health benefits, but their optimal intake levels have not been determined.

Question 4

Because they are not nutrients, high intakes of phytochemical supplements are not harmful.

Accepted Answer

Despite being beneficial in small amounts, high intakes of phytochemical supplements may actually be harmful and toxic to the body. It is always important to consult a healthcare professional before starting any supplementation.

Question 5

Which of the following is NOT a health-promoting function associated with a high intake of plant-based foods?&#10;A)reduction in inflammation that is linked to the development of heart disease&#10;B)slowing of tumor cell growth in the development of cancer&#10;C)decrease in bone loss associated with the osteoporosis&#10;D)enhanced immune function to protect against infection

Accepted Answer

A high intake of plant-based foods has been associated with numerous health benefits, including reducing inflammation, slowing tumor growth, and enhancing immune function. However, there is no evidence to suggest that it decreases bone loss associated with osteoporosis. In fact, some studies suggest that high consumption of certain plant-based foods like beans and grains may increase the risk of osteoporosis due to their phytate content, which can interfere with calcium absorption.

Question 6

Epidemiological studies cannot identify cause-and-effect relationships between food intake and disease.

Accepted Answer

Epidemiological studies can only identify associations between food intake and disease, but cannot establish a direct cause-and-effect relationship. Other factors, such as genetics and lifestyle, may also play a role in the development of the disease.

Question 7

Antioxidants neutralize&#10;A)phytochemicals.&#10;B)free radicals.&#10;C)vitamins.&#10;D)acids.

Accepted Answer

Antioxidants are substances that can prevent or slow damage to cells caused by free radicals, which are molecules produced when the body breaks down food or when exposed to radiation, cigarette smoke or pollution.

Question 8

Which of the following statements is TRUE about the consumption of foods containing phytochemicals?&#10;A)They increase the risk of diseases of aging.&#10;B)They reduce the risk of cancer.&#10;C)They increase the rates of infection.&#10;D)They increase the rates of blood clotting.

Accepted Answer

Phytochemicals are plant-based compounds that have been shown to have benefits in reducing the risk of cancer as well as lowering the risk of other chronic diseases. They do not increase the risk of diseases of aging, infection rates, or blood clotting.

Question 9

Current research suggests that the health benefits of phytochemicals come only in supplement form.

Accepted Answer

Current research suggests that the health benefits of phytochemicals come from consuming them in whole foods, such as fruits, vegetables, whole grains, and legumes, rather than in supplement form. Some studies suggest that taking phytochemical supplements may not have the same health benefits as consuming the whole food sources.

Question 10

Spinach and sweet potatoes are rich sources of phytochemicals.

Accepted Answer

Spinach and sweet potatoes both contain a variety of phytochemicals such as carotenoids, flavonoids, and phenolic acids. These compounds have been associated with various health benefits, including antioxidant and anti-inflammatory properties.
