| Nutrition is one place where you can start, because it is possible to do some practical experiments. But, be warned, you will easily spend a decade investigating it. I picked the subject, because I'm sure that in the end you will have achieved something of great value: your own relatively better health.
(I said relatively, because diet is only one of the factors that influences health, although I say it's an important one) Expanding on the sibling comment by 'mistercheph': 1) Start on a blank slate. have no notion about the subject. This is easier said than done . Un-learning is way more difficult than learning , even for the simplest of topics. 2) Read really old literature on the subject, the likes of Aristotle, the alternative is to listen to people on the internet who have read old literature. Initially do some cross checking to make sure that these people are indeed saying the truth by actually checking the sources they cite. Progressively read the literature to relatively modern times, say up until 100 years back. Many research papers that are over 100 years old are very readable compared to the current ones even for lay people. 3) Experiment on yourself. Come up with your own observations on what is good and bad. 4) now explore the conventional knowledge on the subject. For x amount of time spend on gleaning conventional knowledge, listen to the (1)heretic who takes the opposite stand for x amount of time who says otherwise. 5) do several iterations of steps 1 to 4. 6) Form your own opinion after a decade. (1)= the older credentialed heretic is a good bet. By speaking against the guild that he/she is affiliated with he/she has got a lot to lose : his/her livelihood. Good luck! |
No control group?
> Form your own opinion after a decade
After a decade, differences in your body will mostly be because you are 10 years older.
Such experiments are largely pointless because the only people doing them are people who care about their health. You are more likely to be healthy because of the totality of your life choices, not the specific things you do in the diet experiment.
