Forgive my ignorance. Who created the idea of pranic foods? How did they come to this conclusion? How can it be measured? I have just found out that onion and garlic are negative pranic foods. Gutted as I use them in everything. What effects are these going to have?
The Jains were quite adept in determining this from an ancient period. They don't take potatoes as well from what I remember reading.The ayurvedic medical system also have these ideas.
Prasad is considered to be full of prana, and eating it is considered good for raising the consciousness. Even in terms of physical health it is also quite good, and foods and drink rich in prana has been known to effect healing and cures.
Fresh fruits and vegetables are rich in prana. I have noticed that my meditation is tangibly better when I have taken just fruits.
You can create prasad or increase prana in food through preparing it in a meditative state, or chanting mantras, or prayers. The state of consciousness you have while cooking food leaves an imprint in the food prepared.You can also clearly see that foods or drink prepared and taken in this way, tastes or feels different from the same food which had not been converted into prasad by mantras or meditation. This is also why most of us prefer mom's simple food prepared with love at home than sophisticated food prepared at restaurants with profit as motive.
Processed foods, old and stale food, excess of tea and coffee are considered prana depleters.
