Despite what elitist science types will try to tell you, their experiments, causes, or hypotheses are no more noble than you bagging the present your dog left in the front yard. I no longer believe any scientific findings put forth in magazine articles or academic journals. I still read them; it's always important to stay current with what mainstream society is telling you to believe. That way you know how to find all the holes in their logic.
My problem with "scientific research" is that it is all biased. Scientists have released studies for years about the harms of alcohol consumption: alcohol kills brain cells; it corrodes the liver, which is vital to cleaning one's body; it affects response time and one's sensory cortex. But did you know that alcohol is really good for you? Scientists now say that having one to two drinks per day can decrease one's risk of heart disease.
Maybe you remember the Atkins diet that was so popular 5 years ago. This no-carb diet was vehemently supported by scientific findings when initially introduced, but since then it has been widely deemed as ineffective and even dangerous to eat only high-protein foods. Although I'm guessing the founders of the Atkins Nutritional Approach didn't envision this when they started their no/low-carb diet plan.
My advice: Question everything. Accept nothing. But as those cute little kids from Reading Rainbow always said, "You don't have to take my word for it."
