Compared to other nutritionists in the alternative health field he seems sensor like many of them, but when he talked about indigenous peoples, mushrooms, spring water, sexuality, deer antler extract, well ENTJ seem fine. I wish i could vote EXTJ like sakinorva. ENTJ is the most sensor of the intuitive or at least most sensor NT.

Edit: He really understands the importance of health is from good quality water. Definitely Te over Ti because he doesn't understand the reason why people eat, is because eating food makes you experience a certain MBTI type temporarily.
