I read somewhere that for those for whom sodium exacerbates hypertension, it isn't really only your sodium intake that counts ... it's the relationship between sodium intake and potassium intake.
I use MyFitnessPal to monitor my diet now and again. What I learned:
1. My diet is very low in fat (a surprise to me).
2. It is very easy to eat more sodium than is recommended.
3. It is very hard to eat as much potassium as is recommended.
