Your question: Why doesn't the alkalizing drink taken in the winter time with its high potassium content cause the same problems that high potassium foods like bananas cause when eaten in the winter time? Also, the kelp potassium/sodium balance would be ok in the winter but not in the summer but maybe it's ok because it doesn't have a high potassium content?
End of question.
Answer: Bananas are generally picked green, so this may mean that they have too much Potassium Nitrate in them and do not contain enough of the other Alkaline Minerals needed to provide for the proper Balance !
And Potassium Nitrate is a much worse form of Potassium,Health wise, so this may Cause more problems !
The Blackstrap Molasses does "NOT" contain any Potassium Nitrate in it, and it is very concentrated in ALkaline Minerals besides just Potassium !
Plus if in the winter time you used Good Quality Kelp which is grown in Cold waters, this may mean that it has a Higher ratio of Sodium to Potassium than Kelp grown in warm waters !
Thus by a person taking the Cold water Kelp along with the Blackstrap Molasses and varying the amounts to what one may find Solves the Problem for them, then a person may see Positive Results !
So this Kelp will work Good in both the winter and in the summer, because in the summer a person may eat foods which are already higher in Potassium and so in the summer most people are not getting enough Natural Sodium in their body anyway, so the Kelp helps to solve this problem in the summer , also !
And in the winter if people will learn to eat more winter foods, then they may get more Sodium along with taking more Kelp to Solve their Problems in the winter time, because the Cold weather may be more stressful and thus the need for more Natural Sodium !
Smile Tis your choice.
