information he finds regarding medications, treatments, and diets are accurate. The
first website he finds has a lot of information about a diet plan to help diabetics live
a healthy lifestyle. John can't figure out who the author of the site is, and he notices
that there are a lot of advertisements for a specific diabetic health plan that matches
the one described on the website. Which of these are red flags that indicate he
should continue doing more research elsewhere? Choose the answer.
