Remember, in science, the QUESTION, INTERPRETATION, AND APPLICATION are EVERYTHING. Conducting a research study is elementary. It is the formulation of the question and the accurate interpretation and application of the results that requires intellect, knowledge, and, most importantly, ethics.
Just to give you an idea of how important it is to READ the methodology section and to be able to pose the RIGHT QUESTION, ensure the conclusion is based ONLY on the question posed, and to accurately INTERPRET and APPLY the results, let’s look at a study regarding calcium supplementation in Inuit children.
First, of these 10 "healthy children" 4 had appendix removed, 2 had been treated for cutaneous infection, one had tonsils removed, two were healing from fractured bones, and one had developmental delay. That means ten out of ten had health issues YET these kids were described as HEALTHY subjects. The truth is that all the subjects were from a hospital - who goes to a hospital if they are healthy??
They then fed these kids calcium (from rocks NOT from vegetables or red meat - i.e. blood) and lo and behold the kids had issues. They then concluded that caution should be taken when recommending the standard North American diet to Inuits (I agree, NOBODY should follow these recommendations). They hypothesize that this is because the Inuit have genetically adapted (bb vit D receptor genotype) to low calcium diets and are able to absorb calcium better and thus recommending the North American food guideline calcium daily intake amount may be harmful. These Inuit children had a higher distribution of the bb vit D receptor genotype than whites but similar to many Asians.
