I recall some of the diet trends growing up in the 90's from Slim Fast to Atkins. Most of the results with losing weight came about more from forming some discipline through a routine than the product or food selection itself. The meal replacement drinks made a whole lot of no sense. Ingredients listed were little more than sugar water mixed with milk powder and some soy protein. Essentially starving oneself by drinking that instead of having a proper meal just to end up overeating later in the day because hunger is a spiteful woman.
I never have put much stock into what a news outlet on its own says. Rather show me the data to shift through the allegedly credible sources. They misinterpret the data, reword the numbers (or inflate them) to sound worse (a result of "2% more likely" suddenly becomes "chance at risk doubles!" or "400% increase!"), or misquote the researchers.
Corporations will virtue signal when the profits become potential enough. Browse through Amazon and a number of products have tags for Keto, Paleo, Organic, Natural, etcetera. Obnoxious as the pandering may be, in the end the virtue signaling ends up benefiting everyone availability of options considering. I only wish the prices for some of these "healthy alternatives" weren't so dang high. (A bag of Allulose costs almost four times as much as the same size in regular granulated sugar. Thank goodness I have never been big on using much sugar in anything.) Also, I think some of the tags were slapped on the item there willy-nilly.
As you mentioned, do the research using multiple sources. One person could praise the benefits of caffeine while another condemning the poisons of it. Additionally listen to thy own body. I for one cannot drink anything with caffeine anymore otherwise I get an overactive bladder.
I used to enjoy Ocean Spray cranberry juice but even the "100% juice" ended up not sitting right with my body nor quenching my thirst. Squeezing lemons is a bit of a chore compared to just buying a bottle of the stuff but due to the pasteurization process they use to kill any potential bacteria also removes the healthful benefits from drinking lemon juice to begin with.
