       | Seriously BBC?
       | 
       | The plant based diet (the diet component of being vegan) is found
       | adequate by the WHO for all stages of life.[1]
       | 
       | Now this article if full of picking some studies that have proven
       | that in some case something was wrong with a some form of plant
       | based diet, or less optimal than the form of omni diet the
       | control was on.
       | 
       | And this is true! There are unhealthy plant based diets, and
       | there are quite healthy omni diets. And --thanks BBC for pointing
       | it out once again-- us plant eaters should be careful of some
       | nutrients we may lack (as should omnis) AND some forms food we
       | may over consume (as should omnis). Pretty much the only one that
       | plant based eaters are more lacking in than omnis is B12.
       | Otherwise plant eaters usually score overall BETTER than omnis,
       | but sadly the BBC leaves this information out of this article
       | (meat industry promo piece), gladly they published this kind of
       | info in a separate article 5 DAYS EARLIER.[2]
       | 
       | There are a whole lot of diets within the plant based diet. A
       | particularly healthy one, according to research, is the Whole
       | Food Plant Based diet. And most MDs (which are quite a few)
       | recommending this diet do underline the need for B12
       | supplementation (both in plant eaters and in omnis).
       | 
       | While this article come with a study of 555 Kenyan kids being
       | given omni food scoring better than the group given plant food.
       | Ok.
       | 
       | Let me show you this study:
       | 
       | > In a large representative population study of more than 8000
       | British men and women, intelligence in childhood was associated
       | with a vegetarian diet in mid-adulthood, and this was independent
       | of educational attainment and social class.[3]
       | 
       | It's bigger (n=8000), it in a developed nation (UK), it controls
       | for all kinds of factors and concludes a correlation between
       | intelligence and vegetarianism. No causation though. But I recon
       | the 555 Kenya school children study also did not prove causation.
       | 
       | So? Why would the BBC publish such a piece? In clear
       | contradiction to something they published 5 days earlier? An
       | article that cherry picks to the point it's sneakily suggestive?
       | Every one may judge for themselves but I think it is
       | paid/compensated journalism, at a govt owned outlet. Needles to
       | say, the BBC lost some more point for me today.
