Purslane won't stop growing in the seams between bricks in my driveway. It is another omega 3 source, the richest non-seed one for plants.
There are too many myths about what vegans can't get. I have been vegan 20 years and my bloodwork verifies the approach. B12, D3, free and total testosterone, FSH, T3 and T4 hormones, prolactin, insulin, blood sugar, c reactive proven, tumor necrosis alpha, interluekine 6...everything is in the right range to live to 125. Evidence beats opinions every time.
Anyone here under 44 years old is invited to my 125th....
I think Oscar makes a good point that most people make choices about what to eat on the spur of the moment and include some poor foods. Vegans often take their diets much more seriously and are likely to more than compensate for missing nutrients by making fewer bad choices about what to eat. That is why I think a vegan diet with eggs, seafood, poultry and red meat would be fantastic for your health. I know it doesn't make sense.
I agree it doesn't make sense. You don't have a vegan diet by consuming animal products.
Here is everything a layman needs to know about B12.

And about Vitamin D

On Smallpox and infectious disease. If vaccines are so safe and good for you, then why is anyone associated with producing and administering a vaccine immune from lawsuits and prosecution? A healthy immune system and clean lymphatic system is your best defense against infectious disease.

On protein. There is no reason for a vegan to be lacking in any essential amino acids. They are adequately provided by plant based foods. And I've met several vegan bodybuilders who are not lacking for protein.

On omega 3 - think nuts and seeds (flax, hemp, chia). Nuts and seeds are also good sources of amino acids.

Bottom line, I choose to be vegan for my health, and animal welfare and rights has been a benefit that I've come to appreciate and support since becoming vegan. Research indicates that with a proper vegan diet I will not lack for any nutrients in a plant based diet. My personal belief is that a plant based diet based on primarily raw fruit and vegetables will give my body the best chance for optimal health.
I encourage everyone to do what makes them happy and consume the diet that works best for them. I'm not trying to preach or convert anyone to a plant based diet.
