Sodium dietary recommendations

Vitamins, minerals, and electrolytes— Studies have shown that during moderate to severe stresses, more zinc, copper, magnesium, and calcium are lost in the urine. Furthermore, stress results in altered blood levels of vitamins A and C, and of zinc and iron. Also, part of the response to stress includes water and sodium retention, via veisopressin and aldosterone secretion. As for the water-soluble vitamins—thiamin, riboflavin, niacin, pyridoxine (B-6), pantothenic acid, folic acid, and vitamin C stress increases their requirement. However, no dietary recommendations are made for these nutrients for individuals under stressful situations. Still, it seems wise to supply some supplementation before deficiency symptoms appear. 

HF medications deserves special attention, as it is the most common cause of acute decompensation and can be prevented. As such, an accurate history regarding diet, food choices, and the patient s knowledge regarding sodium and fluid intake (including alcohol) is valuable in assessing dietary indiscretion. Nonadherence with medical recommendations such as laboratory and other appointment follow-up can also be indicative of non-adherence with diet or medications. 

In terms of mineral content, potato is best known as an important source of dietary potassium, which plays a fundamental role in acid-base regulation and fluid balance and is required for optimal functioning of the heart, kidneys, muscles, nerves, and digestive systems. Health benefits of sufficient potassium intake include reduced risk of hypokalemia, osteoporosis, high blood pressure, stroke, inflammatory bowel disease (IBD), kidney stones, and asthma. A high intake of potassium and low intake of sodium have been hypothesized to reduce the risk of stroke (Larsson et al., 2008 Swain et al., 2008). However, most American women 31-50 years old consume no more than half of the recommended amoimt of potassium and men s intake is only moderately higher (lOM, 2004). 

Most national health authorities now recommend increased potassium consumption, along with their advice to cut back on sodium. That s true for the U.S. Dietary Guidelines Advisory Committee the National Academy of Sciences Food and Nutrition Board the National Heart, Lung, and Blood Institute of the National Institutes of Health the American Heart Association Health Canada and the Australian Heart Foundation. The reason for this unanimity is simple the science just can t be denied. Potassium is a chemical element that helps to maintain normal functioning of muscles, the heart, and the nervous system. Potassium is a major regulator of blood pressure.

Based on USDA estimates of per capita consumption of wheat flour, one-third of the adult woman s Recommended Dietary Allowance (RDA) for iron could be obtained if we consumed whole wheat products Q). The iron in wheat, however, is thought to be poorly bioavailable to humans, primarily attributable to the effect of phytate. British investigators found that the iron balance of individuals was lower when they ate largely whole meal bread than when they ate bread made with white flour (2). When the test bread made with white flour contained either sodium or ferric phytate, postprandial serum iron rise was depressed ( ). They theorized that the phytate present in the brown bread formed an insoluble iron salt and rendered the iron unabsorbable. That theory was supported by the work of Moore et al. (4) at Washington University, who tested the response of anemic individuals administered therapuetic doses of ferric... 

In patients with elevated triglyceride levels (>500 mg/dL) and/or LDL between 100 and 129 mg/dL, lifestyle changes are recommended (see Chap. 21). Unfortunately, most patients with CKD have aheady been advised to adhere to difficult dietary regimens, which may include protein, phosphorus, sodium, potassium, and fluid restrictions, as well as diabetic exchanges. Thus although diet therapy is a reasonable first-step approach, it may not be successful in many patients with CKD because of noncompliance. A dietitian who is well versed in the management of kidney disease should be consulted. 

It has been estimated that the average American ingests 7.5-10 g of salt (NaCl) each day. Because NaCl is about 40% (by mass) sodium ions, this amounts to 3-4 g of sodium daily. Until 1989 the Food and Nutrition Board of the National Academy of Sciences National Research Council s defined estimated safe and adequate daily dietary intake (ESADDl) of sodium ion was 1.1-3.3 g. Clearly, Americans exceed this recommendation. 

The Food and Nutrition Board has removed the three electrolytes from its table of estimated safe and adequate daily dietary intake because sufficient information is not available to establish a recommended amount. The major dietary source of sodium and chloride is table salt (40% sodium and 60% chloride). Physicians still recommend that the intake of sodium be restricted to 1-2 g daily. The recommended intake of chloride is approximately 1.7-5.1 g daily. However, getting enough sodium and chloride is not a problem. In fact, sodium intake in the United States is about 5-7 g/day, far in excess of the 1-2 g/day required by a normal adult.

The importance of the minerals and the consequences of their deficiency are well known [28], The mineral contents of Chinese, European, and Japanese chestnuts are listed in Table 11.2 [22], European chestnut has the highest potassium content compared to Chinese and Japanese chestnuts. Magnesium, phosphorus, and manganese contents are higher in Chinese chestnut than in European and Japanese chestnuts. On the other hand, Japanese chestnut contains the highest amounts of calcium, iron, sodium, zinc, and copper contents among these three varieties. The minimum and maximum percentages of recommended dietary allowances (RDA) or adequate intake (Al) of these minerals obtained by...

These reports may be accessed via www.nap.edu A Tolerable Upper Intake Level (UL) is the highest level of daily nutrient intake that is likely to pose no risk of adverse health effects to almost all individuals in the general population. Unless otherwise specified, the UL represents total intake from food, water, and supplements. Due to a lack of suitable data, ULs could not be established for vitamin K, thiamin, riboflavin, vitamin B12, pantothenic acid, biotin, and carotenoids. In the absence of a UL, extra caution may be warranted in consuming levels above recommended intakes. Members of the general population should be advised not to routinely exceed the UL. The UL is not meant to ply to individuals who are treated with the nutrient under medical supervision or to individuals with predisposing conditions that modify their sensitivity to the nutrient... 

Sodium is an important dietary mineral that we eat in our food, primarily as sodium chloride (table salt). Sodium is involved in the regulation of body fluids, and eating too much of it can lead to high blood pressure. High blood pressure, in turn, increases the risk of stroke and heart attack. Consequently, people with high blood pressure should limit their sodium intake. The FDA recommends that a person consume less than 2.4 g (2400 mg) of sodium per day. However, sodium is usually consumed as sodium chloride, so the mass of sodium that we eat is not the same as the mass of sodium chloride that we eat. How many grams of sodium chloride can we consume and still stay below the FDA recommendation for sodium ... 

In small amounts, the fluoride ion (often consumed as NaF) prevents tooth decay. According to the American Dental Association, an adult female should consume 3.0 mg of fluorine per day. Calculate the amount of sodium fluoride (45.24% F) that a woman should consume to get the recommended amount of fluorine. 78. The iodide ion, usually consumed as potassium iodide, is a dietary mineral essential to good nutrition. In countries where potassium iodide is added to salt, iodine deficiency or goiter has been almost completely eliminated. The recommended daily allowance (RDA) for iodine is 150 /ig/day. How much potassium iodide (76.45% 1) should you consume to meet the RDA ...
