question 4 (5 points)
which naturally occurring substances found in plants can help prevent chronic diseases?

a) nitrosamines
b) acrylamides
c) phytochemicals
d) free radicals

Explanation:

🆕 New Concept Discovered: Plant Bioactive Compounds
Naturally occurring protective plant chemicals.

Step 1: Analyze the options

• nitrosamines: These are organic compounds, many of which are carcinogenic (cancer-causing). They are typically formed in foods containing nitrites when cooked at high temperatures, rather than being protective plant substances.
• acrylamides: This is a chemical compound that can form in some foods—mainly plant-based foods rich in carbohydrates—during high-temperature cooking processes like frying, roasting, or baking. It is classified as a potential carcinogen, not a protective substance.
• phytochemicals: The prefix "phyto-" means plant. Phytochemicals are bioactive, naturally occurring chemical compounds found in plants. They act as a defense system for the plant and provide significant health benefits to humans, including antioxidant properties that help prevent chronic diseases like cardiovascular disease and cancer.
• free radicals: These are unstable, highly reactive atoms or molecules that can cause cellular damage (oxidative stress) in the body, leading to chronic diseases. They are not protective substances found in plants.

Step 2: Identify the correct substance

Phytochemicals (such as flavonoids, carotenoids, and polyphenols) are the naturally occurring compounds in fruits, vegetables, grains, and beans that help protect cells from damage, thereby reducing the risk of chronic diseases.

Answer:

c) phytochemicals
