Welcome!. Hyperinsulinemia (chronic high insulin) can lead to high BP, so controlling that can help. High insulin signals the kidneys to retain sodium and excrete potassium (see this, though ironically the MD/PhD author recommends a 70% carb calorie diet to get a potassium to sodium ratio of 4:1 on intake, the high carb diet will increase insulin, however). The quickest way to drop BP is to water fast. Though this can lead to "low carb flu" at least partially because of electrolyte disturbances (a lot of sodium excretion).. If oxalates are not an issue for you (though excess oxalates can damage kidneys leading to high BP), you can try beet root powder as a supplement as it can increase nitric oxide.
