I've been on a fruitarian diet for 4 years now (previously raw vegan for 7 years & no animal products for 15 years). I have never used any supplements. Being a fruitarian means no greens, roots or seeds.
You need a good balance in your diet, meaning various organic fresh fruit. In the begining you might have to make sure to eat based on the nutrients (oranges have loads of calcium, olives are acid fruit -rare, & needed to keep the balance in the bifidus of your body that holds the B12- banana or mangos or avocados for the proteins, kiwis for the zinc, etc. Then your body will be able to ask for what it needs. Try to eat what seems appealing.
The colors of the fruits is very important & is what will make your body react. I would also suggest that you exercize & try to find a good sleep. The roots of a good health are: food (raw fresh organic fruit) exercize & sleep.
Have a nice journey! More.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
