SODIUM MAXIMUM 1.5 grams of sodium or 3.8 2.3 grams of sodium or 5.8 grams of salt (just<br />

under a teaspoon of salt daily--almost a 1/2 teaspoon) daily. Most women get twice that.<br />

Excessive sodium intake can cause high blood pressure, a major risk factor for heart disease, stroke<br />

and kidney disease.<br />

CHLORIDE MAXIMUM 2.3 grams daily<br />

Although chloride isn't listed on Nutrition Facts panels, you can regulate your intake by watching<br />

how much sodium you consume and keeping your daily salt intake under a teaspoon.<br />

Salt is hidden in most foods for flavor. So most people are already getting to much please use salt<br />

substitutes like the Desi salt substitutes listed in this book.<br />

Calcium (Ca)<br />

The bones are a dynamic store of the calcium in the body. They are constantly under the influence<br />

of the hormone calcitonin, which promotes bone growth and decreases calcium levels in the<br />

blood, and parathyroid hormone, which does the opposite. Calcium is bound to the proteins in<br />

the bloodstream, so the level of calcium is related to the patient's nutrition as well as the calcium<br />

intake in the diet.<br />

Conditions of Calcium Imbalance<br />

Hypercalcemia (hyper= too much + calc=calcium + emia= in the blood) is associated with "moans,<br />

stones, abdominal groans"; symptoms include kidney stones, abdominal pain, and depression.<br />

Also, too much calcium can be associated with heart rhythm disturbances. Causes include<br />

parathyroid tumors, other tumors including breast cancer, excess amounts of Vitamin A or D,<br />

Paget's disease, and kidney failure.<br />

Hypocalcemia (hypo=too little) is usually associated with eating disorders or lack of parathyroid<br />

hormone. Symptoms include weakness, muscle spasms, and heart rhythm disturbance.<br />

Bicarbonate (HCO3)<br />

This electrolyte is an important component of the equation that keeps the acid-base status of the<br />

body in balance.<br />

Water + Carbon Dioxide = Bicarbonate + Hydrogen<br />

The lungs regulate the amount of carbon dioxide, and the kidneys work with HCO3. This electrolyte<br />

helps buffer the acids that build up in the body as normal byproducts of metabolism or when<br />

the body malfunctions and too much acid is produced (for example: diabetic ketoacidosis, renal<br />

tubular acidosis)<br />

Potassium<br />

Potassium is a very important mineral for the proper function of all cells, tissues, and organs in<br />

the human body. It is also an electrolyte, a substance that conducts electricity in the body, along<br />

with sodium, chloride, calcium, and magnesium. Potassium is crucial to heart function and plays a<br />

key role in skeletal and smooth muscle contraction, making it important for normal digestive and<br />

muscular function, too. Many foods contain potassium, including all meats, some types of fish<br />

(such as salmon, cod, and flounder), and many fruits, vegetables, and legumes. Dairy products are<br />

also good sources of potassium.<br />

Having too much potassium in the blood is called hyperkalemia; having too little is known as<br />

hypokalemia. Keeping the right potassium balance in the body depends on the amount of sodium<br />

and magnesium in the blood. Too much sodium -- common in Western diets that use a lot of salt<br />

-- may increase the need for potassium. Diarrhea, vomiting, excessive sweating, malnutrition,<br />

malabsorption syndromes (such as Crohn's disease) can also cause potassium deficiency, as well<br />

as use of a kind of heart medicine called loop diuretics.<br />

Most people get all of the potassium they need from a healthy diet rich in vegetables and<br />

fruits. Older people have a greater risk of hyperkalemia because our kidneys are less efficient at<br />

eliminating potassium as we age. Older people should be careful when taking medication that may<br />

affect potassium levels, such as nonsteroidal anti-inflammatory drugs (NSAIDs) and ACE inhibitors<br />

(see section on Interactions).<br />

Whatever your age, talk to your doctor before taking potassium supplements.<br />

Hyperkalemia (hyper=too much + kal=potassium + emia=in the blood) is a potentially lifethreatening<br />

situation because it causes abnormal electrical conduction in the heart and potentially<br />

life-threatening heart rhythm problems. High potassium levels are most often associated with<br />

kidney failure, in which potassium levels build up and cannot be excreted in the urine. Emergency<br />

dialysis is often required to remove the potassium.<br />

Hypokalemia (hypo=too little) is most often seen when the body loses too much potassium from<br />

causes like vomiting, diarrhea, sweating, and medications such as diuretics or laxatives. It is often<br />

seen in diabetic ketoacidosis, where potassium is excessively lost in the urine. Since chemicals in the<br />

body are related in their metabolism, low magnesium levels can be associated with hypokalemia.<br />

Research has been done on removing potassium from potatoes for hyperkalemia patients<br />

During early research in 1969, potatoes were sliced into 1/8th-inch slices or diced into small dicesize<br />

cubes and soaked in heated water (122 to 140° F) for two hours. The water volume was 10<br />

times more water than potatoes. Next, the potatoes were rinsed and boiled in five times more<br />

water for five minutes. This method of soaking and then boiling the potatoes reduced potassium<br />

from 400 milligrams per every 100 grams (equal to 2/3 cup) of potatoes to 211 milligrams for<br />

cubes and 90 milligrams for thinly sliced potatoes.<br />

Bone Health<br />

At least one study shows a positive link between a diet rich in potassium and bone health. More<br />

research is needed to determine whether a diet high in potassium can reduce bone turnover in<br />

people.<br />

Hypokalemia<br />

The most important use of potassium is to treat the symptoms of hypokalemia (low potassium),<br />

which include weakness, lack of energy, muscle cramps, stomach disturbances, an irregular<br />

heartbeat, and an abnormal EKG (electrocardiogram, a test that measures heart function).<br />

Hypokalemia is usually caused by the body losing too much potassium in the urine or intestines;<br />

it's rarely caused by a lack of potassium in the diet. Hypokalemia can be life-threatening and<br />
