Postprandial Effects of a High Potassium Meal

The investigators aim to evaluate the acute effects of potassium supplementation achieved by ingestion of potassium rich food, on vascular health.


Many studies have shown that an increase in potassium through the diet or through potassium pills helps to lower blood pressure. Also, the amount of oral potassium taken can improve how well the participants blood vessels work. These studies have focused on potassium given in the form of a pill. The investigators are interested in the effect of potassium consumed through food sources and how it will effect arterial health and blood pressure. The world health organization (WHO) recommends a K⁺ intake of at least 3510 mg/day from food for adults, excluding those with impaired K⁺ excretion. In this study the investigators aim to provide approximately 75% (approximately 2000 mg) of the total daily recommended intake for potassium in one meal. The investigators do not know whether dietary potassium (not pill form) will acutely improve the arterial health and if it will cause a decrease in blood pressure. The investigators hypothesis to see an improvement in vascular function following a high potassium meal compared to a low potassium meal.

Medical and Biotech [MESH] Definitions

An autosomal dominant familial disorder characterized by recurrent episodes of skeletal muscle weakness associated with falls in serum potassium levels. The condition usually presents in the first or second decade of life with attacks of trunk and leg paresis during sleep or shortly after awakening. Symptoms may persist for hours to days and generally are precipitated by exercise or a meal high in carbohydrates. (Adams et al., Principles of Neurology, 6th ed, p1483)

A delayed rectifier subtype of shaker potassium channels that is the predominant VOLTAGE-GATED POTASSIUM CHANNEL of T-LYMPHOCYTES.

Unstable isotopes of potassium that decay or disintegrate emitting radiation. K atoms with atomic weights 37, 38, 40, and 42-45 are radioactive potassium isotopes.

A shaker subfamily of potassium channels that participate in transient outward potassium currents by activating at subthreshold MEMBRANE POTENTIALS, inactivating rapidly, and recovering from inactivation quickly.
