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. | | 1: https://www.plantbasednews.org/lifestyle/the-largest- | organiz... | | 2: https://www.bbc.com/future/article/20200122-are-there- | health... | | 3: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1790799/ | SeanFerree wrote: | Great article! | KitDuncan wrote: | What a weak article and study.

I read it, and | wondered why potato was chosen? Just to make the point, I | guess; but that speaks to the sensationalist urge plaguing | the author. | | There was also no information about any conflicts of | interest. I'd be interested in knowing if there were any? | Zod666 wrote: | I don't know much about this, so please correct me if I'm | wrong, but plant based omega 3's have a horrible conversion | rate don't they? | ovx99 wrote: | They have a lesser conversion rate, but what most | paleo/anti-vegan arguments neglect to mention in terms of | plant omega-3 sources is that if you simply eat more | total ALA, the net omega-3 will be the same to your body. | Seems obvious, but people never seem to acknowledge that. | It's not such a lesser conversion rate that this isn't | practical or possible. Not to mention there's studies | showing alternative benefits of ALA despite having less | conversion rate overall. Similarly with krill oil -- | there's less EPA/DHA compared to fish oil per gram but | it's utilized differently by the body and has shown | variations in bioavailability when measured (krill vs | fish oil is an ongoing topic of interest). | markstos wrote: | I have more energy since shifting towards a vegan diet-- mid-day | slumps are rare now and I have more energy after work in the | evening as well. | | Work on complex coding and DevOps tasks continues as before. | mrits wrote: | I bounce back and forth. I don't notice any difference in | thoughtfully planed diet that does or does not contain meat. | I'm pretty active (marathon runner, weight lifting etc) so I'm | particularly sensitive to diet changes. It's hard to be vegan | without food prep which is what can really skyrocket your | health | dogma1138 wrote: | Was your previous non-vegan diet actually good? As in high on | fibrous veggies, moderate amount of complex carbs, low on sugar | and high on high quality protein? | | When people switch to vegan they essentially rely more on home | cooked meals and stay away from junk it doesn't mean that a | vegan diet is better than a non vegan diet of the same quality. | | If you switch from twinkies to lentil patties and cauliflower | rice it's no wonder that you feel better. | abfan1127 wrote: | I came here to say this. When I switched from a typical | American diet of crappy carbs, soda, and other sugar based | crap to a, High Fat, High Protein diet, I got a ton of | energy, slept better, etc. While I see a ton of value in my | dietary choices, it was the lack of sugar that made life | better. | somehnguy wrote: | I did the keto diet for the majority of last year to lose | weight. It was extremely successful and I lost 75 pounds. I | noticed the exact same thing you did in regards to energy | levels and overall just feeling better. My energy levels | did not fluctuate at all during the day, even post heavy | meals. I also didn't seem to have any of those random days | where you just feel like you're dragging along. I was also | exercising heavily 4-6 days a week though, I'm sure that | had some part in everything. | | After a major (unrelated) surgery that left me basically | incapacitated for 6 months I went back to a normal diet and | low exercise. The difference in overall energy and | wellbeing is astounding. I plan to go back to keto soon | actually in hopes of achieving the extremely predictable | energy levels again. | Relys wrote: | Probably due to eating less simple carbs and sugars. | radicalbyte wrote: | I had the same results from both a vegan diet and a whole foods | diets. | | Both diets largely excluded processed food (I'd eat tofu, | fermented sauces in both, and some high quality ham in the | whole food diet). | | I think that the large ratio of vegetables and lack of simple | sugars was the cause more so than the meat. | | I get a similar boost when following body-building diets, these | include simple sugars around training time and highly processed | whey isolate. I have always used them to drop weight too so | you're running at a calorie deficit. On those diets I've felt | fantastic except the day after the binge day (you need to have | a surplus once every 7-10 days to avoid starving). | ianai wrote: | Yep, I feel a definite boost in decisiveness when I take my | morning B12 lozenge. Which we should all be taking btw... | goldenkey wrote: | Wild, sustainably caught fish is the diet to go for if you care | about the environment and your own health.

Also, sourcing sustainability | isn't an exact science in most first world countries. | ianai wrote: | I really doubt wild fish can be sustainably caught. We | shouldn't be fishing them at all, I'd claim. | Polylactic_acid wrote: | This is a pretty well written article. Hopefully people read past | the headline. The most important bit being "could" affect. Some | limited tests have been done on kids which found some difference | but its not clear if it has any effect on adults. | | It also sounds like a vegan diet with a few nutritional | supplements could entirely solve the issue. At the very least we | know that we can hugely reduce our meat consumption with positive | outcomes. | Dumblydorr wrote: | How is it well written? They make claims about massive swaths | of the global population based on a single study from an | African school giving kids snacks. | ovx99 wrote: | From the article: | | "Other [nutrients] are found in vegan foods, but only in meagre | amounts; to get the minimum amount of vitamin B6 required each | day (1.3 mg) from one of the richest plant sources, potatoes, | you'd have to eat about five cups' worth (equivalent to roughly | 750g or 1.6lb).

Very interesting! I wonder what percentage of | readers of this article are going to investigate what this | authoritative science writer says for themselves? After all, why | not trust the expert with a graduate degree working for the BBC? | | So which is it, is the author unable to investigate in the most | basic manner the actual B6 content in foods, when she apparently | has a doctorate, or is this some sort of propagandist trash | article with an agenda? Because I'm not sure what other options | there are based on the way the quoted paragraph is written. | | Moreover, what are the implications for the BBC's editorial | standards that something like this was greenlit? | cies wrote: | > is this some sort of propagandist trash article with an | agenda? | | I'm seriously thinking this is paid journalism. | | The BBC published this article a mere 5 days earlier: | | https://www.bbc.com/future/article/20200122-are-there-health... | | A much more balanced article if you ask me. Both journalists | are freelancers. | rusk wrote: | The BBC really needs to be listed as an unreliable source. | ianai wrote: | I get these same arguments from non-vegans all too often.

You could eat only potato | chips and drink soda and be vegan. Saying "vegan diet" by itself | is pretty meaningless. | ianai wrote: | This is incorrect. B12 is made from bacteria widespread in the | "wild environment ", but almost completely washed it of the | modern diet. The only reason non-vegans don't typically have to | worry about B12 is that cyanocobalamin or other B12s are added | into common foods. There's an argument that cyanocobalamin is bad | for you though as your liver creates cyanide in processing it for | use in your body. Here's the quote from the article. | | """ One of the most well-known challenges for vegans is getting | enough vitamin B12, which is only found in animal products like | eggs and meat. """ | amriksohata wrote: | According to the game changers documentary, even meat like | chicken has to have added vitamins like b12 which is the only | reason meat eaters get that extra vitamin, so supplementing is | for all | frandroid wrote: | > As for Gandhi, he eventually abandoned his illicit relationship | with meat, and went back to vegetarianism. | | That was a commitment he took for his mother when he went to | study law in England. While today the UK is a hotbed of veg*nism, | back then Gandhi had trouble eating well while being veg in | London, and started seeking out other vegetarians. He eventually | found a vegetarian society, and it is through that society that | he became exposed to Henry David Thoreau and his Civil | Disobedience. | | The rest, as they say, is world history. | cgh wrote: | Great to see they mentioned creatine and carnosine. Creatine in | particular is notable for its proven effectiveness as an athletic | supplement but it has a host of other, lesser-known benefits[0]. | It's only found in animals, although your body does produce | baseline amounts from other amino acids. | | 0. https://examine.com/supplements/creatine/ | theatraine wrote: | Kombucha is a great vegan source of B12, one of the key nutrients | mentioned in the article. The B12 in kombucha actually comes from | the culture itself. | frandroid wrote: | Neat! | jnaddef wrote: | TL;DR There is no scientific study proving one way or the other | and whether you are vegan or not if you do not care about the | quality and diversity of what you eat it will probably affect | your body and your brain. ___________________________________________________________________ (page generated 2020-01-28 23:00 UTC)
