Sometimes information provided in hundred-year-old magazines just leaves me scratching my head. For example, here’s a question I never would have thought of asking – and I have no clue whether the answer is correct.
Are Salted Nuts More Digestible Than Unsalted Ones?
YES! Nuts should never be eaten in any quantity without the addition of salt. The bulk of the protein of the nut is a substance called globulin, which is soluble in salt solution. Therefore, the addition of salt to the nut aids in its solution and digestion. This factor should not be so important in the case of roasted nuts, but even here salt, by making the nuts more palatable, aids in starting off their digestion, which is at best somewhat slow.
