If vegetarians don't actually need dietary supplements any more than meat eaters do, then I'm pleased to hear it.

Such a question cannot be answered with yes or no. I'ld like to avoid extremism (I, being open-minded, didn't even had a case), but even the Vegetarian Society doesn't ignore the possible B12 deficiency.

Vegetarian Society wrote:
Diets which exclude all animal products need to ensure that they obtain their recommended daily intake from fortified sources or supplements.

...

According to the British Nutrition Foundation, dietary deficiency is rare but it can sometimes occur in vegans who obtain virtually no B12 in their diet.

...

For people not eating any animal products, yeast extract and other fortified/supplemented foods such as breakfast cereals, soya milks, soya/veggie burgers, and vegetable margarines are all good sources.

If we assume that the Vegetarian Society is advocating a case, then the word recommended is important, and there's more than one provider of B12, including but not limited to supplements.

In general supplements aren't required, so the answer may be no. But I'm not sure what a veggie actually eats, so the answer can be yes. The word recommended is a save option, so the veggie has to answer the own yes/no question.

I have no reason to assume, believe nor think that the Vegetarian Society is wrong, dangerous or denying a B12 deficiency.

The vegetarian diet can be a delicious, satisfying and completely balanced one with the addition of just one natural supplement:

Meat.

True, I believe. Going back to B12, it is produced only by micro-organisms. So I suppose it depends on whether the "exploitation" of those micro-organisms fits one's definition of vegan, or not.

Only bacteria have the metabolic mechanisms required to produce B12. Animals absorb the vitamin as it's produced by bacteria in the gut. Humans have evolved to require more than their own bacteria produce, and so need to eat B12-containing foods, which for all practical purposes means meat.

B12 is the most chemically complex of all vitamins, and also needs a complex chain of reactions for the body to absorb and use it properly, so it's quite possible for someone to be B12-deficient even if they eat a complete and balanced diet.

Given your enthusiasm for bacon in particular, you will probably be distraught to hear that sales of meat, and bacon and sausages in particular, have been plummeting over the past year (down nearly 122 million on bacon and 51 million on sausages), whilst sales of fruit and vegetables have risen by around 176 million over the same period. http://www.bbc.co.uk/news/uk-38406591

I wouldn't be distraught about it, falling sales usually would prompt competitive pricing, so cheaper bacon and bangers!

The detail in that piece is rather scant, also the report it refers to is I think a paid item from Neilsen, certainly the link goes to the Neilsen home page and there doesn't seem to be an easy link to it from there. The suggestion is that fruits and veggies increased by 176 million from Avocados, raspberries and blueberries, wouldn't surprise me, 3 of the most expensive fruits available!
