There are so many vegan ‘experts’ online today you have to double check everything you see. Especially about vegan nutrition.
I remember when I first started my life as a vegan I heard that vegans must take iron supplements or they could die. And this was from a so called vegan expert on YouTube. Of course most vegans don’t have any issues with iron. If you eat a whole food diet that is of a wide variety of foods you should be fine. But just like non-vegans, there are some that do need iron assistance. But not everyone.
Dr. Michael Greger is one of the most respected authorities on plant based diets and veganism. His site nutritionfacts.org is a wealth of information on vegan nutrition and scientific studies. Recently he was asked what the top 3 vegan myths about nutrition were. His answers were entertaining and informative as always. I especially find #3 to be absolutely true and so many people ignore it. Get all 3 of his top vegan myths on the next page.
