Thus, a balanced salt intake is essential to reap its health benefits while reducing associated hazards.
Sources of Sodium
Let’s certainly examine the numerous sodium sources in greater detail:
- Seafood naturally contains sodium, such as fish and shellfish.
- Even if the salt concentration fluctuates, it adds to the total amount of sodium consumed.
- Milk, cheese, and yogurt are dairy products that naturally contain sodium.
- This results from sodium’s inclusion in animal diets and its role in preserving cellular processes.
- One of the primary sources of dietary sodium is table salt, commonly known as sodium chloride (NaCl).
- At the table and while cooking, it is used to season food.
- Processed foods like chips, pretzels, and crackers frequently have salt added for flavor enhancement and shelf stability.
- Because salt is added to canned vegetables, soups, and sauces for preservation and flavor, they may include sodium.
Fast food and eating spots
- Salt is frequently added to fast food and restaurant items to improve flavor, which can considerably increase daily sodium intake.
- The salt content of deli meats, bacon, sausages, and canned meats is often high to prolong shelf life and improve flavor.
- Pre-packaged frozen meals and pizzas frequently have higher sodium content for taste and preservation.
- There is sodium present naturally in some mineral waters. The salt concentration can, however, change significantly across various products.
Sauces and Seasonings
- Salad dressings, ketchup, soy sauce, and barbecue sauce are a few examples of sauces that can add flavor to food while also being high in sodium.
- Due to their techniques of preservation, condiments, including pickles, olives, and some relishes, are sodium-rich foods.
- Salt is often added to commercially made bread and rolls for flavor and preservation.
- For flavor, salt may be added to some pastries and baked items.
Supplements and Medications
- Salt is an ingredient in certain over-the-counter and prescription medications.
Supplement with electrolytes
- To help keep the electrolyte balance, sodium may be included in electrolyte tablets and supplements.
Age-related differences in sodium requirements reflect how people’s nutritional needs change as they mature. Following is a breakdown of suggested daily sodium intake levels by age:
- Infants (0-6 months): Adequate intake: 120 mg/day
- Infants (7-12 months): 370 mg/day
Infants obtain sodium from breast milk or formula.
- Children (1-3 years): 1000 mg/day
- Children (4-8 years): 1200 mg/day
- Children and adolescents (9-13 years): 1500 mg/day
- Adolescents (14-18 years): 1500 mg/day
- Adults (19-50 years): 1500 mg/day
- Adults (51-70 years): 1300 mg/day
- Adults (71 years and older): 1200 mg/day
Here are some possible adverse effects of consuming a lot of sodium:
High blood pressure
- Consuming too much sodium can raise blood pressure, which increases the risk of cardiovascular conditions like heart attack and stroke.
- Swelling in the extremities and other body areas might result from too much salt, which can cause water retention.
- Dehydration or over hydration may result from an electrolyte imbalance and other factors.
Difficulties with kidney function
- High sodium consumption can stress the kidneys, resulting in decreased kidney function and a higher risk of kidney stones.
