Is there a single food that you can survive on forever?
By Ellen Airhart September 18, 2017
Potatoes are awesome, but not enough to live off of them forever.
For all of 2016, Andrew Taylor ate only potatoes. There were a few caveats: He ate both white potatoes and sweet ones, and sometimes mixed in soymilk, tomato sauce, salt and herbs. He also took B12 supplements. But, overall, he ate potatoes for breakfast, lunch, and dinner. He took four blood tests over the year which he claims all came back normal. He even lost weight and felt more energized.
