Question

which scenario best demonstrates a reliable approach to evaluating nutritional information?
a. rob follows an untested diet plan promoted by a website selling expensive weight - loss supplements.
b. austin believes a celebrity endorsement on social media about a \miracle cure\ for weight loss.
c. shanna refers to research - backed guidelines from the usda and cdc for accurate nutrition advice.
d. lisa trusts a blog post claiming that green tea alone can \melt fat\ without checking scientific sources.

Explanation:

To determine the reliable approach, we analyze each option:

• Option A: Following an untested diet plan from a commercial website (selling supplements) is unreliable as it's likely biased for profit.
• Option B: Believing a celebrity endorsement on social media for a "miracle cure" is unreliable, as celebrity endorsements don't guarantee scientific validity.
• Option C: Referring to research - backed guidelines from USDA (United States Department of Agriculture) and CDC (Centers for Disease Control and Prevention) is reliable. These organizations conduct and base their guidelines on scientific research, so their advice is accurate and trustworthy for nutritional information.
• Option D: Trusting a blog post without checking scientific sources is unreliable, as blog posts can be based on anecdotes or misinformation.

Answer:

C. Shanna refers to research - backed guidelines from the USDA and CDC for accurate nutrition advice.
