Overweight, physical activity, blood pressure, and hypertension

Overweight, obesity and blood pressure Body weight is a determinant of blood pressure at all age; in fact: it has been estimated that the risk of developing elevated blood pressure is two to six time higher in overweight than in normal-weight individuals; there is a linear correlation between blood pressure and body weight or body […]

Potassium intake, blood pressure and hypertension

Potassium intake and blood pressure High dietary potassium (K+) intakes and blood pressure are inversely related: animal studies, observational epidemiological studies, clinical trials, and meta-analyses of these trials support this. Furthermore, the prevalence of hypertension tends to be lower in populations with high K+ intakes than in those with low intakes. Finally, an increase in potassium intake […]

Sodium: blood pressure, requirements, intake, sources

Sodium and blood pressure A high sodium (Na+) intake (the main source is salt or sodium chloride, NaCl) contributes to blood pressure raise, and hypertension development. Many epidemiologic studies, animal studies, migration studies, clinical trials, and meta-analyses of trials support this, with the final evidence from rigorously controlled, dose-response trials. Furthermore, in primitive society Na+intake is […]

Metabolic acidosis and “modern diet”

Metabolic acidosis and pH level Life depends on appropriate pH levels around and in living organisms and cells. We requires a tightly controlled pH level in our serum of about 7.4 (a slightly alkaline range of 7.35 to 7.45) to avoid metabolic acidosis and survive. As a comparison, in the past 100 years the pH of […]
