Wow. This passes for science? We really need a safe, unobtrusive device that can record body's micronutrient intake on a daily basis.

Great, then I can also get mandatory personalized ads based on my current exact nutritional needs!

  You sure Amazon didn't patent that yet?

  Uh.. why.

    Because how would you implement it? - Using a camera: can't detect micronutrients - Using barcode/RFID in the packaging: you can't have this in all types of food. - Using some kind of sensor: devices that can detect micronutrients are way too large to be "unobtrusive". - Letting the user enter the data: will never work.

Sure! Start broad, trying to determine what may be interesting and then design stricter and stricter experiments.

Unfortunately yes, that's the problem with a lot of the studies people are making life decisions on, psychology, dietary supplements... Between studies funded by companies and/or authors with conflict of interest, unreliable methods (in vitro antioxidants) or cohorts selection issues (grad students that need the money so they lie on selection interviews for experiments or trials)... In those cohort studies, what people eat is highly dependent on their wealth, education, localisation, jobs... And they rarely control for everything (mostly because it is impossible and if they asked people to remember instead of giving them devices they don't may not have the money to spend on a carefully designed experiment).

Yes. All studies have limitations. You report them and interpret the results accordingly.

  My interpretation is that the results aren't very certain.

    Science wins again.

  My interpretation is the results are about as trustworthy as if they were using shiny hair in Instagram photos as a proxy for vitamin E levels.

Every time you see a food study like this look at the details. You'll be surprised how often the data are based on these questionnaires.

This is how most nutrition "science" is conducted.
