The average US diet is deficient in numerous essential nutrients. You can eat healthy on a plant based diet or omni diet, but just adding or removing animal products is still not going to make an unhealthy diet healthy.
Mostly amino acids. There are simple rules to follow to ensure you get complete nutrition and amino acid profiles. Otherwise what nutrients are you really missing?
That link doesn't really have anything to do with whether or not vegan/vegetarian diets are missing choline. It's that the UK nutritional chart doesn't track choline at all. It has nothing to do with diet. I was super confused at how this paper had anything to do with the conversation except to say choline exists and is important. Afterwards I googled and choline isn't exclusive to meat sources so I'm still confused what vegetarian/vegan diets and choline deficiency have to do with each other- very common vegan/vegetarian foods are high in choline like brocoli, peas, chickpeas, various legumes, etc.
Could you cite studies that correlate vegetarian/vegan diets with deficiencies in nutrition?
“The primary sources of dietary choline are found in beef, eggs, dairy products, fish, and chicken, with much lower levels found in nuts, beans, and cruciferous vegetables, such as broccoli.
In 1998, recognising the importance of choline, the US Institute of Medicine recommended minimum daily intakes. These range from 425 mg/day for women to 550 mg/day for men, and 450 mg/day and 550 mg/day for pregnant and breastfeeding women, respectively, because of the critical role the nutrient has in fetal development.
In 2016, the European Food Safety Authority published similar daily requirements.

‘This is....concerning given that current trends appear to be towards meat reduction and plant-based diets," says Dr Derbyshire.’”
Sorry, most of the article appeared to be about that UK isn't releasing daily choline requirements so I was a little confused. It also doesn't say whether or not there's actual evidence that choline deficiency due to a vegetarian diet exists, much less is linked to something?
