>5.3 A vegan diet is not vegan A vegan diet itself is not even vegan under its own premises because it's not "practicable" to follow. It demands an opportunity cost of time, research and money that could be utilized in a better way and even then is not guaranteed to be efficient because it emphasizes purity. The entire following around veganism represents a Nirvana Fallacy[1] and is the reason why the majority of people quit: Perfect is the enemy of good[2]. A vegan diet makes it harder, and for many people impossible, to follow productive consumer approaches such as buying local, seasonal or supporting regenerative agriculture.

Vegans will always say that "you can get X nutrient from Y specific source", but a full meal plan with sufficient quantities will essentially highlight how absurd a "well-planned" vegan diet is
1) Vitamin B12
2) Vitamin B6 (Pyridoxal, Pyridoxamine)
3) Choline
4) Niacin (bio availability)
5) Vitamin B2
6) Vitamin A (Retinol, variable Carotene conversion)
7) Vitamin D3 (winter, northern latitudes, synthesis requires cholesterol)
8) Vitamin K2 MK-4 (variable K1 conversion)
9) Omega-3 (EPA/DHA; conversion from ALA is inefficient, limited, variable, inhibited by LA and insufficient for pregnancy)
10) Iron (bio availability)
11) Zinc (bio availability)
12) Calcium
13) Selenium
14) Iodine
15) Protein (per calorie, digestibility[1], Lysine, Leucine, elderly people[2], athletes)
