“Raw” almonds are actually dead in the US. You can’t improve the nutrition because the pasteurization process has essentially killed them. A raw almond that would benefit from soaking would also be the same almonds that you could plant and grow. In the United States you aren’t able to purchase true “Raw” almonds. This is a one of those nutrition myths perpetuated everywhere without people actually verifying its validity.
Maybe in Canada where Brendan Brazier is from you are able to soak true raw almonds. I don’t know about other countries.
