Vegan diets are not nutritionally complete, even with supplements.

The sources do refute your point; I can tell that you have not read them, as you ignored addressing the part of my comment about bioavailability (which two of these sources mention).

Second comment following up on my other one. Your own links undermine your own argument.

From your second source:

> Carefully constructed vegan diets could provide adequate amounts of all six priority micronutrients for the general population, except vitamin B12, which would need to be consumed through fortified foods or supplements.

Further, the opening paragraph of your third link undermines your entire argument as well

> Diets that limit the consumption of animal source food to very low levels require careful fortification or supplementation, and the inclusion of specific nutrient-dense plants. If these cautionary measures are neglected, vegetarian and, especially, vegan populations risk to suffer from deficiencies in some key animal source food-associated nutrients."

It specifically says that vegan populations risk deficiencies when not including nutrient-dense foods and fortification/supplementation. It specifically does not say that full nutrition is impossible without animal products.

Event the title implicitly supports my argument: "Not all (micro)nutrients are easily obtained from plants." Emphasis on "easily."

The word "cannot" only appears alongside B12. The phrase "does not" doesn't appear alongside any nutrients intake. And the word "impossible" doesn't show up at all.

Are you sure that you read the articles you're claiming that I did not read?

I did look at your sources. They describe lower bioavailability and nutrient density, and have advisements for supplementation and a diverse diet. Low density and bioavailability does not mean non-existent. Low bioavailability does not mean not at all bioavailable. Can you point to a specific line that says it is impossible to obtain a nutrient in sufficient quantities on a vegan diet, even with supplementation? The third link seems to be the most related to your point, but I don’t think it says what you’re arguing, from what I can see. I’m sorry to say that the links are long and I going to need you to point me to lines that support your thesis.

Edit: Hopefully you read this after this edit, if not can address as a followup. Here is a page on the NHS specifically referencing how all nutrients can be obtained on a vegan diet: https://www.nhs.uk/live-well/eat-well/how-to-eat-a-balanced-....
