[quote="Ava Odoéména"][quote="Lindis"][quote="fredrikw"]Yeah, no products containing D3 is vegan
When I read things like that, I cant help of wonder; are we really ment to be vegans if our bodies cant be satisfied with all vitamins from a vegan diet?????
I remember when I was just like you, and every nutritional news which seemed unfavorable towards the vegan diet resulted in minor identity crisis.
It's actually a good and healthy response to radically question what you are doing - if you have the right thought model to be able to scratch out the truth.
Now one thing is important to remember. As vegans, we are in a hostile environment where our sheer existence causes people to have moral stress. This stress they project unto us, seeking ways to make vegans look bad. So your first job is, when you read something which is seemingly antivegan, to figure out where that info comes from and what the sender intends to achieve with the info.
As mentioned before, the now refuted science that D3 is more powerful than D2 (BTW, food is an irrelevant source of Vitamin D, apart from sundried mushrooms) immediately got huge response internationally and in EU-Europe, Vitamin D2 even got pulled from supplements. Now that it has been rehabilitated it may return again, I hope, we'll see.
It just goes to show that you need to observe these kind of reports with a cool distance, this actually comes naturally once you've culturally established as a vegan.
That you haven't done that, is very evident by your question. The answer to your question BTW, is, that evolutionary, humans are omnivores, so we are are meant to eat any diet within that scheme which supplies us with all the required nutrients. A vegan diet is within the realm of being omnivores. In fact, humans being omnivores is an argument *for* the vegan diet and not against it, because just because we can eat everything doesn't mean we must eat everything. We have the liberty to make conscious choices about which parts of the omnivorous diet supply us with all essential nutrients. The vegan diet can do that, but just like learning Chinese grammar there is some "vegan nutrition grammar" to learn and implement.
The bottom line here is: the vegan diet is in no way inferior and in many ways superior compared with an "all-eating omnivore diet". But you have to know where you source your nutrients, you may source them differently from all-eating-omnivores. Like non-heme iron, having vitamin C as in peppers, parsley or apple juice mineral water mix part of your dish enhances your iron absorption. A spice quantity of Arame algae added to your food will supply it with iodine. A Brazil nut a day will give you plenty of selenium, just as whole wheat grains products will. Vitamin D is generated in your skin from UVB-rays, however sundrying freshly harvested mushrooms will also generate storable Vitamin D for you to consume in winter. All Northern people, vegan or not need way more Vitamin D than originally thought, up to 1000IU per 25lb / 11kg bodyweight. That means a person who weighs 220 lb / 100 kg needs 8800IU of Vitamin D. The RDA currently is 400IU....
Nutritional science is a very young science and findings have a short half-life.
It is your responsibility to learn "vegan nutrition grammar" just like it is for a person to learn Chinese who is planning to live in China. If you learn insufficient Chinese, you'll suffer in China and if you are OK and prepared you'll have a smooth ride.
Same goes in Veganism. YOU need to be able to get a good foundation of "vegan nutrition grammar", once that is done, you'll laugh about some of the news reports. Like the one when they claimed that Tofu makes your brain shrink. It turned out that the problem was aluminum poisoning of the water in which the Tofu was made...
So don't be scared, be informed!
