The Cleveland Clinic. “Flaxseed: Little Seed, Big Benefits. How and Why You Should Be Adding Flax to Your Diet”: Flaxseed benefits. Why do dietitians love flaxseed? Let us count the ways:…Flaxseed is a good source of high-quality plant protein, comparable to soybeans. Potassium. Potassium is a mineral that’s important for cell and muscle function and helps maintain normal blood pressure. But many Americans don’t get enough. Enter flaxseed, which has more potassium than (the famously potassium-rich) bananas. (19)

The normal plasma potassium concentration is 3.5–5.0 mmol/L. Most potassium is inside cells and potassium is the main ion affecting the resting membrane potential of nerve and muscle cells. Abnormal plasma potassium levels can cause life-threatening cardiac arrhythmias including cardiac arrest and should be treated promptly. Abnormal plasma potassium levels can arise from changes in the total body potassium content or from shifts of potassium into or out of cells.

Potassium intake decreased with the agricultural revolution when energy intake shifted from a variety of plants including potassium-rich tubers to cereals. Potassium intake then further decreased with a shift to highly refined processed foods (Weaver, 2013). Naturally, potassium is found mostly in fruits and vegetables. Potatoes are a high source of potassium (300 mg/100 g). But for Americans, the top dietary potassium sources are milk, coffee, chicken and beef dishes, orange and grapefruit juice, and potatoes. Potassium in foods is present with phosphate, sulfate, citrate, and many organic anions including proteins.
Thyrotoxic periodic paralysis: a presentation of hyperthyroidism increasing in frequency around the world
Published in Journal of Endocrinology, Metabolism and Diabetes of South Africa, 2023
The true pathogenesis of thyrotoxic periodic paralysis has largely remained uncertain. Severe acute hypokalaemia is the main laboratory finding with the severity of hypokalaemia being directly proportional to the severity of the paralysis. Normalisation of serum potassium levels leads to resolution of the muscle weakness. Skeletal muscle holds the largest proportion of total body potassium stores, thus playing a vital role in extracellular potassium homeostasis.4 Hypokalaemia in the setting of thyrotoxicosis occurs due to a transcellular potassium shift, from the extracellular into the intracellular (mainly muscle) compartment. There is no true potassium deficit. The main access points for potassium movement in skeletal muscle include the Na/K ATPase and K+ channels, as well as inward-rectifying potassium channels (Kir) and delayed rectifying potassium channels – all of which are stringent in maintaining extracellular potassium homeostasis.11
A nonlinear measurement error model and its application to describing the dependency of health outcomes on dietary intake
Published in Journal of Applied Statistics, 2022
Potassium is an essential nutrient that is necessary for normal cell function. Evaluating an individuals' potassium status, however, is not straightforward as the nutrient is found inside our cells and levels measured in the blood can only provide a limited view of potassium status [24]. In our application we will focus on individuals' potassium intake from food. Potassium is a nutrient that is commonly found in foods such as fruits, vegetables, meats, poultry, fish, milk, yogurt, nuts, whole-wheat flour, brown rice, and potatoes. Potassium, is not however, typically found in refined starches (such as white wheat flour or white rice), fortified foods, and sodium-rich processed foods that are increasingly becoming a part of individuals' diets in the United States [39].
Effect of carbohydrate–electrolyte consumption on insulin, cortisol hormones and blood glucose after high-intensity exercise

Electrolytes are the minerals with electrical transmission capacity which become ions in the solution. The electrolyte balance of the body is necessary for the normal functioning of the cells. The changes occurring in the electrolyte balance as a result of dehydration of the body impair the cardiovascular and thermoregulatory functions. The main electrolytes important for exercise performance are sodium, chloride, and potassium. Of these, sodium is the main positive ion in the extracellular fluid and helps to regulate acid–base balance, neurotransmission, blood pressure and muscle function. Whereas potassium is the main cation in the intracellular fluid and helps to preserve the electrical activity of the nerves, skeletal muscles, and heart. In addition to this, potassium aids in carbohydrate metabolism by increasing the transport of glucose and glycogen storage (Ziegenfuss et al. 2015). Previous studies have demonstrated that carbohydrate–electrolyte ingestion after exercise has positive effect on athletes’ which inhibits to cortisol, regulates the glucose concentrations with electrolytes and it increases the insulin levels (Davis and Brown 2001, Haff et al. 2003, Evans et al. 2009).
