A sodium-restricted diet focuses on substantially reducing the intake of table salt, which is particularly important for individuals with cardiovascular and renal conditions. This dietary approach promotes heart health, assists those with hypertension and atherosclerosis, and leads to improved test results as well as an extended and enhanced quality of life.
Effects of excess salt in the diet
Excessive salt intake in the diet has been demonstrated in a number of epidemiological studies. A positive correlation was found between too high a dietary intake of salt and increased mortality from cardiovascular disease. One study was the INTERSALT study. It involved more than 10 000 people from over 32 countries. The results of the study clearly indicated that in the diets of people with high salt sensitivity (14.626, 3 g/day) the incidence of cardiovirus disease, including hypertension, is lower than in the group with a sodium diet of 11.714, 6 g.
Where's the salt hiding?
Salt and sodium in it are present in greater or lesser quantities in every food product. Natural products contain relatively little salt. Approximately 60% of the salt we consume throughout the day comes from cooking salt, the rest comes from the finished products we eat. Studies show that most of the sodium we eat in our diet is delivered to the body by drinking baking soda and drinking mineral/source water with a high melting content.
A low-sodium diet is the rule
The rules of the low-sodium diet are very simple. They are to limit as much sodium as possible. The World Health Organization allows for no more than 1 tablespoon of cooking salt per day including products that we don't get (ready-made products). So the main rule of a low-sulfur diet is to avoid salt in the kitchen. Reducing the amount of NaCl in the diet is one of the most effective ways to prevent heart disease.
Low-sodium diet recommended and prohibited products
The low-sodium diet is characterized by the total exclusion or significant restriction of foods containing a significant or moderate amount of sodium. To each of us, the first thing that comes to mind are salted products raspberries, chips, pulses, popcorn. Few, however, will think of the most common products we use, which are not at all green in taste, to the extent that we can take them into account.
Low-sodium diet Indications
The low-sodium diet is recommended for people who are struggling with cardiovascular diseases such as high blood pressure and heart failure. It turns out that the low-Sodium Diet can also be used successfully in kidney diseases like kidney failure and renal arthritis.
