Skin, blood pressure, rheumatoid arthritis and gamma-linolenic acid

Healthy skin and gamma-linolenic acid gamma-Linolenic acid (GLA), an omega-6 essential fatty acid, like its precursor linoleic acid (the most abundant polyunsaturated fatty acid in human skin epidermis, where it’s involved in the maintenance of the epidermal water barrier), plays important roles in the physiology and pathophysiology of the skin. Studies conducted on humans revealed that gamma-linolenic acid: improves skin moisture, firmness, […]

Alcohol, blood pressure, and hypertension

Contents in brief: Alcohol intake and blood pressure Alcohol intake and prevention of hypertension Relationship between ethanol intake and blood pressure References Alcohol intake and blood pressure Many studies have shown a direct, dose-dependent relationship between alcohol intake and blood pressure, particularly for intake above two drinks per day. This relationship is independent of: age; […]

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 […]
