La DIETA de Hipopotasemia

La hipopotasemia es una condición en la que el nivel en sangre de potasio es inferior a la normal. En el organismo, el potasio controla las contracciones musculares, ritmo cardíaco influencias y desempeña un papel integral en el funcionamiento del sistema nervioso. La hipopotasemia puede desarrollarse como resultado de los efectos de la enfermedad o la medicación. En raras ocasiones, es el resultado de consumir una dieta pobre en potasio.
Significado
Una dieta baja en potasio, pero rica en alimentos salados pueden jugar un papel en la hipertensión, explica el sitio web de Colorado State University Extension. Los atletas que no pueden consumir suficiente potasio en la dieta pueden experimentar calambres musculares durante y después de un entrenamiento. Las personas con potasio crónicamente baja puede sentirse débil y con náuseas. Ellos pueden tener un ritmo cardíaco irregular o rápido.
Identificación
Para encontrar alimentos ricos en potasio, se inician en la sección de productos. La mayoría de las frutas y las verduras contienen potasio. Las frutas secas son especialmente altos en potasio. La carne y el pescado también contienen potasio al igual que los productos lácteos. Frijoles, lentejas y arvejas también son buenas opciones, mientras que los huevos, los cereales y los aceites no son generalmente altos en potasio.
Características
Una dieta para la hipocalemia incluye alimentos que se consideran buenas fuentes de potasio. Bacalao, lenguado, sardinas, atún, carne de res, cerdo y cordero son buenas opciones, mientras habas, frijoles y pistachos también contienen altos niveles de potasio. La leche, el yogur, el requesón y miel aportan una cantidad significativa del mineral. Ricas en potasio son las frutas ciruelas, melones, aguacates, dátiles, plátanos, naranjas y muchos otros. Ricas en potasio incluyen verduras setas, calabazas, batatas, espinaca, col rizada y otros, indica el sitio web de la Universidad de Massachusetts Medical School.
Beneficios
Dietas Hyokalemic se solicita para el potasio bajo en la sangre correcta. Se pueden usar en combinación con un suplemento de potasio prescritas por el médico. El mantenimiento de un nivel normal de potasio puede ayudar a prevenir complicaciones médicas cardíacas y otros. Comer una amplia variedad de frutas y verduras le permite conseguir más potasio necesario fibra, vitaminas y minerales.
Consideraciones
Antes de comenzar una dieta hipopotasemia, asegúrese de que entiende todas las restricciones nutricionales que debe seguir. Su médico también puede recomendar un bajo contenido de sodio, una dieta baja en grasa o bajo en calorías, cada uno de los cuales influirán en su alto contenido de potasio opciones de comida. Elegir alimentos que no han sido procesados ​​es mejor que consumir los alimentos preenvasados ​​que contienen sal, la grasa y las calorías. Home alimentos crudos, tales como sopa de verduras, proporcionan potasio excelente. Una mezcla de la fruta combinando melones, cítricos y plátanos es otra buena opción.

HYPOKALEMIA DIET

Hypokalemia is a condition in which the blood level of potassium is below normal. In the body, potassium controls muscle contractions, influences heartbeat and plays an integral role in the functioning of the nervous system. Hypokalemia may develop as a result of illness or medication effects. Rarely, it is the result of consuming a potassium-poor diet.

Significance

A diet low in potassium but high in salty foods may play a role in hypertension, explains the Colorado State University Extension website. Athletes who fail to consume enough dietary potassium may experience muscle cramps during and after a workout. People with chronically low potassium may feel weak and nauseated. They may have an irregular or fast heartbeat.

Identification

To find potassium-rich foods, begin in the produce section. Most fruits and vegetables contain potassium. Dried fruits are especially high in potassium. Meat and fish also contain potassium as do milk products. Beans, lentils and peas are also good choices while eggs, grains and oils are usually not high in potassium.

Features

A diet for hypokalemia includes foods that are considered good sources of potassium. Codfish, flounder, sardines, tuna, beef steak, pork, and lamb are good choices, while lima beans, kidney beans and pistachios also contain high levels of potassium. Milk, yogurt, cottage cheese and molasses contribute a significant amount of the mineral. Potassium-rich fruits include prunes, honeydews, avocados, dates, bananas, oranges and many others. Potassium-rich vegetables include mushrooms, acorn squash, sweet potatoes, spinach, collard greens and others, indicates the University of Massachusetts Medical School website.

Benefits

Hyokalemic diets are ordered to help correct low blood potassium. They may be used in conjunction with a physician-prescribed potassium supplement. Maintenance of a normal potassium level can help prevent cardiac and other medical complications. Eating a wide variety of fruits and vegetables allows you to get needed potassium plus fiber, vitamins and minerals.

Considerations

Before beginning a hypokalemia diet, make sure you understand all the nutritional restrictions you should follow. Your physician may also recommend a low-sodium, low-fat or low-calorie diet, each of which will influence your high-potassium food choices. Choosing foods that haven't been processed is better than consuming prepackaged foods that contain added salt, fat and calories. Home-cooked foods, such as vegetable soup, provide excellent potassium. A fruit mixture combining melons, citrus fruits and bananas is another good option.

Importance Potassium for the human body

Referring now to natural potassium, which ingest daily through food. Potassium is present in nature only as cation (positive ion). Cation is the most important of all cells of human and animal bodies, and essential for cell function. Foods rich in potassium are bananas, meat, apricots, kiwis, currants, potatoes, cauliflower, cabbage, fennel, spinach and celery, also mushrooms and walnuts.
The healthy human body is able to regulate and tolerate well high potassium intake with food. This means that a high potassium intake by eating lots of bananas, for example - does not cause an increase in potassium in cells. Another thing would be if ingiriéramos potassium whose natural composition had changed due to a high concentration of potassium That potassium-40.1-40 located on the ground in large quantities as a result of war it absorb through food. But it can also reach the human body through dust clouds.
It is a fact of chemistry that isotopes of a chemical element can not be distinguished from each other chemically. The biochemistry of metabolism of humans, animals and plants can not therefore distinguish between potassium-39, potassium-40 and potassium-41. The body handles the mixture of isotopes that are offered. It is impossible to separate the radioactive potassium nonradioactive in metabolic processes.
Potassium is the most important factor of bodily radioactive contamination
98% of potassium present in the body is inside cells, and only 2% outside. "The radioactive load in humans comes primarily potassium-40, and is about 0.2 millisievert per year. If the concentration of potassium-40 is multiplied by one hundred, the load reaches a very worrying level (20 mSv / a!) "1 is clear then that the radioactive isotope potassium-40, which investigated areas is multiplied by hundred, to be transported to the cells with food intake, damage the vital functions of the kernel - the cell more sensitive to radioactivity - and cell organelles, particularly the mitochondria.
Mitochondria: the powerhouse of the cell
To understand the importance of the function of mitochondria, a brief digression to explain. Mitochondria are oval formations length about 300-800 nm and about 100 nm thick, and are, together with the core, the larger organelles of the cell. Are coated with a double membrane and are in the vicinity of the cell nucleus. Mitochondria have own DNA (deoxyribonucleic acid, carrier of genetic information), and therefore have the capacity to synthesize their own proteins. They are the "respiratory system" of the cells and their main function is the synthesis of ATP (adenosine triphosphate), the most important energy carrier for all metabolic processes. So they are also called the "power plants" of cells.
Damage to the cell Self Repair
Energy in the form of ATP is required, inter alia, for the production of the antioxidant glutathione (GSH) content in the cell fluid soluble. GSH is the primary system repair most cell structures that have been damaged by free radicals. These free radicals are chemical particles with large reactive power, and the radioactivity (ionizing radiation) causes formation.
GSH also has a protective function against chemical mutations (changes in the genetic information produced by certain substances), which represent a danger to the cells. It is considered that this antioxidant function of GSH protects against cancer because it neutralizes the effects of free radicals. But without ATP energy carrier can not produce sufficient GSH, and the repair mechanism of the cells stops funcionar.2 Potassium-40 cells which reaches through the nucleus damaged food and synthesis ATP in the mitochondria and, thereby, the repair process.
Faults in removing heavy metals
The GSH serves another important function: helps cells to get rid of toxic heavy metals. The heavy metals are bound to GSH and are transported from the cell to the gallbladder, which are eliminated. This process has a dual role: first, can liberate excess cells GSH and secondly, metal detoxify heavy.2 so why is understood deteriorating the irreplaceable function of mitochondria due to the presence of radioactive substances, such as potassium-40, has such devastating consequences.
Variation dangerous electrolyte concentration
The ATP from the "power plants" of cells needed in another function essential to human life. The cellular and bodily fluids are, due to ions that possess electrolytes. The presence of certain ions in biological membranes of cells and cell organelles in these membranes produce electric potentials necessary for the vital functions. In this regard, it is of fundamental importance above all the relationship between sodium ion and potassium. Inside the cell is more potassium, sodium abroad more. The balance between sodium and potassium is maintained through the combined effect of the sodium-potassium pump and the permeability of the cell membrane. The sodium-potassium pump is an enzyme system which requires a high energy input, consumes 30% to 70% of adenosine triphosphate (ATP) which is formed in the body. The fundamental importance of ATP as we have referred previously to explain the function of mitochondria. Without an adequate supply of ATP, faults occur in the sodium-potassium pump and altered permeability of the cell membrane. These disturbances cause dangerous finally variations in the electrolyte concentration intra and extracellular space and produce, among other effects, a change in cell volume.
These explanations highlight the fundamental importance of potassium to maintain vital body functions.
