If you or someone close to you is experiencing high blood pressure, one of the contributing factors could be excessive salt intake. Have you ever assessed how much salt you consume daily?
Excessive Salt Consumption: A Modern Concern
Salt is an essential part of the diet, but excessive consumption has become a significant health issue in modern eating habits. Understanding where salt comes from, its health effects, and how to reduce intake can help improve overall well-being.
Sources of Sodium and Salt in the Diet
Sodium, primarily consumed as salt (sodium chloride), is present in various foods both naturally and as an additive. Processed foods, such as ready-made meals, processed meats, snacks, and preserved products, often contain high levels of added salt. Additionally, condiments, sauces, and even certain bread varieties contribute to daily sodium intake.
Here’s an overview of natural sodium levels in different foods:
Seafood (naturally higher due to ocean water exposure)
Shrimp: ~140–300 mg sodium per 100g
Salmon: ~40–60 mg per 100g
Cod: ~50–100 mg per 100g
Clams: ~500–700 mg per 100g
Meat & Poultry (naturally low, but sodium increases with processing)
Chicken (raw): ~50–80 mg per 100g
Beef: ~50–70 mg per 100g
Pork: ~40–60 mg per 100g
Eggs: ~60–90 mg per egg
Dairy
Milk: ~40–50 mg per 100mL
Cheese: ~100–700 mg per 100g (varies by type, with harder cheeses being higher in sodium)
Yogurt: ~40–60 mg per 100g
Vegetables (naturally low, but some exceptions)
Spinach: ~80–120 mg per 100g
Celery: ~70–90 mg per 100g
Beets: ~60–90 mg per 100g
Carrots: ~40–50 mg per 100g
Fruits (generally very low in sodium)
Apples, bananas, berries, oranges: <5 mg per 100g
Cantaloupe: ~10 mg per 100g
Legumes & Grains
Beans (unsalted, cooked): ~0–15 mg per 100g
Rice, oats, quinoa (cooked): ~0–5 mg per 100g
Nuts (unsalted): ~1–5 mg per 100g
Seaweed (Exceptionally High in Natural Sodium!)
Nori (dried seaweed): ~500–1,500 mg per 100g
Wakame: ~800–1,200 mg per 100g
Kombu: Up to 2,000 mg per 100g
Health Implications of Excessive Salt Intake
Too much salt in the diet is linked to several health concerns, including:
High blood pressure (hypertension) – A major risk factor for cardiovascular diseases like heart attacks and strokes.
Kidney strain – Excessive sodium can impair kidney function, potentially leading to kidney disease.
Calcium loss – Increased salt intake may cause calcium depletion, affecting bone health.
Water retention – High sodium intake can lead to bloating and edema.
Recommended Salt Intake
Health experts recommend limiting salt intake to minimise health risks. Guidelines suggest that:
Adults should consume no more than 5–6 grams of salt per day (approximately one teaspoon). 6 grams of salt = 2.4g of sodium. This is the total amount of salt from all sources, including the amount converted from natural sodium to salt.
The body requires around 1.5 grams of salt per day to get the necessary sodium for essential functions.
Most people consume more than the recommended limit due to hidden salt in processed foods.
The maximum allowed amount of 6 g of salt per day can be obtained by eating any of the following:
13 g of bouillon cube
140 g of salted herring
250 g of ketchup
300 g of potato chips
350 g of wieners
400 g of cheese
500-600 g of bread
The Role of Sodium in the Body
Despite the risks of excessive intake, sodium plays crucial roles, including:
Transmission of nerve impulses
Maintaining water balance between blood and tissues
Regulating acid-base balance in the blood
Supporting muscle contraction
However, the need for sodium varies based on body weight, physiological conditions (illness, vomiting, diarrhoea), and physical activity levels that lead to excessive sweating. So with heavy sweating or diarrhoea the need for sodium may be higher.
How to Reduce Salt Consumption
Reducing salt intake involves a mix of dietary choices and cooking habits:
Choose Fresh, Unprocessed Foods: Fresh vegetables, fruits, berries, whole grains, lean meats, and legumes naturally contain low sodium levels.
Processed Foods: Buy ready-made meals and salty semi-finished products as rarely as possible (pizza, sandwiches, burritos, tacos, frozen dinners, chips, popcorn, crackers, pretzels, salted butters, salted nuts).
Read Food Labels: Check sodium content and select products labeled as "low-sodium" or "no added salt." Mineral water can also contain large amounts of sodium. Be sure to read the label on the package. In some cases, for example, in cases of heavy sweating, drinking sodium-rich mineral water is justified.
Cook at Home: Preparing meals from scratch allows control over salt content. Use herbs, spices, and citrus for additional flavour rather than adding excessive salt.
Limit High-Sodium Condiments: Use sauces, mayonnaise, dressings, and spreads sparingly.
Balance Your Meals: If your meals are high in salt, balance your sodium intake – add foods high in potassium such as fresh fruits and vegetables to your menu
Be Mindful When Dining Out: Request that dishes be prepared with less salt if possible and avoid adding extra salt at the table.
Gradual Reduction: Slowly decrease salt intake so taste buds can adjust.
Understanding Salt in Foods and Labels
Many processed and packaged foods contain hidden sodium.
Salt content is often listed on nutrition labels, either per 100g/ml or per portion.
Sodium may also be contained in additives. For example, sodium nitrite, which must be written on the label either as “preservative sodium nitrite” or as “preservative E 250”.
The total salt amount on the label includes both added salt and naturally occurring sodium, using the formula: 1 gram of sodium = 2.5 grams of salt.
If the food does not contain added salt, the packaging may state that the salt content is only due to the presence of natural sodium.
Types of Salt and Their Differences
While there are various types of salt, their health impacts remain the same. Key types include:
Sea salt: Naturally evaporated seawater, contains trace minerals.
Rock salt: Mined from underground deposits, contains trace minerals calcium, potassium, magnesium, iron. May contain impurities.
Table salt: Refined and processed for purity, often iodised.
Iodised salt: Fortified with iodine to support thyroid health. I often recommend to my clients to use to iodised salt or mix it into their other salt and use it when cooking to help to make sure they get the necessary iodine from the diet. If you do have thyroid conditions (hyperhyroid, Hasimoto's Thyroiditis), please consult with your healthcare provider about the iodine intake through salt.
Pan salt: Reduced sodium content, replaced with potassium chloride and magnesium sulfate.
Celtic salt (Sel Gris): Harvested from tidal salt flats along the coast of France, particularly in Brittany. Contains magnesium, calcium, potassium, and other trace minerals.
Himalayan Pink salt: Mined from ancient salt deposits in the Punjab region of Pakistan, near the Himalayas. Contains trace amounts of iron, calcium, potassium, and magnesium, but not in significant amounts for health benefits
Any salt is not a significant source of minerals. Which means that you do not have to eat salt to obtain minerals. Although some salts may contain more minerals than regular table salt, they cannot be considered a source of the corresponding minerals (except iodised salt). With reasonable consumption amounts, regardless of the salt used, the amounts of minerals (except sodium) obtained are very small. Considerable sources of minerals are cereals (especially whole grains), potatoes, fruits and vegetables and berries, milk and dairy products, fish, (poultry) meat, eggs, added dietary fats, nuts, seeds.
Conclusion
The human body needs sodium, but excessive intake leads to severe health risks. Processed foods often contain hidden sodium, making it essential to read labels, choose fresh foods, and limit high-sodium ingredients. By making gradual changes, you can train your palate to enjoy less salty foods while protecting your long-term health.
