I found some YouTube videos that seem interesting.
This interviewer asks people on the street what a Vegan is. It seems to show that Veganism is an unknown thing to a lot of people.
Now here is a Vegan who does explain what Veganism is.
Now, non-Vegans think that Vegans are undernourished in some sort if they're not getting the required nutrients such as:
Calcium, Iodine, Vitamin B12, and Vitamin D
Soy products (tofu, tempeh, etc etc)
Nuts (Almonds, Brazil Nuts, Cashews, Chestnuts, Hazelnuts, Macadamia Nuts, Pecans, Pine Nuts, Pistachio Nuts, Walnuts)
Seeds (Chia Seeds, Flaxseeds, Pumpkin and Squash Seeds, Safflower Seeds, Sesame Seeds, Sunflower Seeds)
Legumes (Peanuts, Black Beans, Chickpeas, Kidney Beans, Lentils, Lima Beans, Pinto Beans, Soybeans, White Beans)
Sea Vegetables ( Arame, Wakame, Spirulina)
Sea Vegetables ( Seaweed, Nori, Kelp, Arame, Kombu, Alaria, Wakame, Laver)
Soy products (tofu, tempeh, etc)
is actually produced in our bodies anyways. It's produced in our small intestine.
Few cases of Vitamin-B12 deficiency are reported.
Fortified Sprouted Multi-grain breads
also created in our bodies
Sun exposure is wonderful for this vitamin to be produced in our bodies!
and even if you are not Vegan,
Not everyone gets enough of this D vitamin. No matter how much sun you get
This is actually something that must be supplemented. By EVERYONE. Vegan or Non-Vegan.
No matter how much you are out in the sun!
What I recommend as far as a Vitamin Supplement is:
Vitamin Code Raw D3 Garden of Life
It contains raw vegan ingredients to help build up the Vitamin D absorption from the sun!
You can probably find these Vitamins at any Health food grocery store. Or you can buy online.
Hope this helps!
