 Role of Salt Restriction



Salt plays an important role in hypertension and that hypertension is associated with proteinuria and more rapid progression of chronic kidney disease (CKD)Salt intake also contributed to edema seen in many patients with proteinuric kidney diseaseDietary salt should be restricted in those with hypertension and/or edemaThe recommendation is to restrict salt to about 4 g/day.

 Who Guidelines for Hypertension



High sodium consumption (>2 g/day, equivalent to 5 g salt/day) and insufficient potassium intake (<3.5 g/day) contribute to high blood pressure and increase the risk of heart disease and strokeThe main source of sodium in our diet is salt although it can come from sodium glutamate, which is used as a condiment in many parts of the worldMost people consume too much salt – on average 9–12 g/day or around twice the recommended maximum level of intakeSalt intake of <5 g/day for adults helps to reduce blood pressure and risk of cardiovascular disease, stroke, and coronary heart attack. The principal benefit of lowering salt intake is a corresponding reduction in high blood pressureThe WHO Member States have agreed to reduce the global population's intake of salt by a relative 30% by 2025Reducing salt intake has been identified as one of the most cost-effective measures countries can take to improve population health outcomes. Key salt reduction measures will generate an extra year of healthy life for a cost that falls below the average annual income or gross domestic product per personAn estimated 2.5 million deaths could be prevented each year if global salt consumption was reduced to the recommended level.

 Recommendations for Salt Reduction



For adults: The WHO recommends that adults consume <5 g (just under a teaspoon) of salt per dayFor children: The WHO recommends that the recommended maximum intake of salt for adults should be adjusted downward for children aged 2–15 years based on their energy requirements relative to those of adults. This recommendation for children does not address the period of exclusive breastfeeding (0–6 months) or the period of complementary feeding with continued breastfeeding (6–24 months)All salt that is consumed should be iodized or “fortified” with iodine, which is essential for healthy brain development in the fetus and young child and optimizing people's mental function in general.

 Sodium



There is an urgent need to reduce salt intake in India. There are >50 studies connecting salt intake and blood pressure and the benefit of reducing salt intakeIt should be made clear salt or sodium added to the foods which include sodium bicarbonate, monosodium glutamate, and sodium lactate besides sodium chloride (table salt)Breads, biscuits, and all other processed foods may have salt sometimes more than a packet of wafersThe food safety and standards authority of India FSSAI, which makes it mandatory for packaged goods to display nutritional facts, does not insist on information of salt. Few products that list salt imply sodium per 100 gm. “if there is 5 g of sodium in 100 g of food, multiply it by 2.5 to understand the salt in itIt should be understood 1-g salt = 400-mg sodium.

 How to Reduce Salt in Diets



Patients should be explained how much is 4 g of salt, salt spoons can be given, or salt sachets can be usedThey should be told to cook food without salt and add salt after cooking that way the salt intake can be controlledget used to low salt to allow the taste buds to recovereat fresh food when possiblenot to add extra salt on the table (a special problem in India since salt is served in the food plate as a routine and salt shakers for soups)It is essential to target the young college and school students and educate them about the ill effects of processed foodIt is a myth that Indians require more salt due to the weather and sweatingThe maximum salt lost is in urine (that's why 24-h urine sodium is measured to calculate a person's salt intake). Sweat once acclimatized has very low sodium. Increased sweating requires more water intake and not salt.

 Salt Adjuncts



Patients should be advised various recipes to enhance the taste in low-sodium foods. Adjuncts such as

HerbsAmchur powderSpring onionsKokumTamarindVinegar can be usedLow-salt chutneys can be made as a side dish to make the meal look more palatable.Ready to use idli, dosa, dhokla, and cake batter have a lot of added sodium in various forms, patients should be explained this, and the recipes for the same should be shared without addition of it.

 Idli



Ingredients

Urad dal – 1 katori (soaked for 3–4 h)½-katori cooked rice3-katori idli rava.

Methods

Grind the soaked urad dal with ½-katori cooked riceTake the idli rava and mix it with the batterFerment it overnight and this batter can be used to make idlis.

 Dosas



2-k rice flour¾-k ravaMix and make a batter which can be used to make dosas.

 Rava Idli



Ingredients

3-cup sooji/rava (semolina)1-cup curd and 2-tbsp whole-wheat flour4-tbsp poha (powdered using a mixer)1/4th-tsp mustard seeds2-tbsp oilPinch of hing (asafoetida) and 2 sprigs of curry leavesSalt as required.

Method of preparation

Soak rava in curd, adding enough water so that it resembles a typical idli batter. The consistency has to be neither too thick nor too thin. A semi-pouring consistency would be idealAllow the batter to ferment for over 8 h. (Fermentation makes the batter lighter and releases good bacteria, which is good for the human gut.)After the batter is fermented, add whole-wheat flour (aata) and powdered poha to the batter. Aata helps to bind the sooji and poha adds texture. In case you do not have poha, you can add powdered kurmura. Heat oil in a pan, add mustard seeds, hing, broken cashew nut pieces, and curry leaves and let it cracklePour the tempering/tadka over the batter. You can even add boiled vegetable puree to your batter. Boiled carrot puree, palak puree, and beetroot puree will make your idlis look colorful and attractive. Add very little salt to the batterSteam the idlisAfter the idlis are steamed, allow them to cool a little before demoldingServe hot.

 Sponge Cake



Ingredients

4 eggs100-g sugar100-g self-rising flour (maida)½-tsp vanilla essence.

Methods

Beat eggs and sugar till thick like custardAdd maida and mix well by fold methodBake in a greased dish in a preheated oven at 180°C–200°C for 20–25 min.

 Role of Albumin



If the patient is leaking proteins, the serum albumin also needs to be monitored and low albumin levels should be corrected; low albumin levels can sometimes cause hypotension.

 Fluid Restriction



Fluid restriction may be required to those patients who are edematous or have a low urine output. It is very important to explain to the patients that fl uid restriction does not mean just restricting water, it implies everything that is fl uid at room temperature.

 Summary



Dietary protein restriction retards the progression of CKD. However, it should be used only in those who are nutritionally adequate. It should not induce malnutritionRestricting protein intake below 0.6 g/kg/day is possible by supplementing essential amino acid or their keto acid (KA)By restricting nitrogen intake, there is reduced generation of uremic toxins and thus improvement in symptoms.When closely monitored, nutritional status can be maintained.In patients without active underlying disease, KA-supplemented diets significantly delay the need for renal replacement therapy.
