A balanced diet is essential for good health, and moderate salt intake plays a key role in that. While salt is a vital ingredient in our diet, excessive consumption can lead to serious problems such as high blood pressure and cardiovascular complications. In this article, we'll explore in detail why we need salt, the consequences of excessive consumption, and how to adjust it appropriately to our individual needs.
Why do we need to consume salt?
Salt, also known as sodium chloride , is composed of 40% sodium and 60% chlorine . It is a mineral necessary for the proper functioning of our bodies. Although often associated with negative things, sodium plays vital roles in our bodies.
Sodium is essential for:
- Regulate the amount of water: Maintains water balance within cells and contributes to proper hydration of the body.
- Controlling blood pH: It helps maintain an adequate level of acidity in the blood to avoid imbalances that affect health.
- Transmit nerve impulses: It is essential for communication between nerve cells and the muscular system.
- Relax muscles: Ensures effective muscle contraction and relaxation.
The human body needs small amounts of salt to perform all these functions. However, excessive consumption can disrupt these functions and lead to health problems.
The risks of consuming too much salt
Excessive salt consumption can have negative consequences for our health. One of the first signs is fluid retention , which results in a feeling of bloating and heaviness.
Furthermore, increased sodium in the blood leads to an increase in the volume of blood the heart needs to pump, resulting in elevated blood pressure . This condition, known as hypertension , is the leading risk factor for cardiovascular diseases such as heart attacks and strokes.
Other associated risks include:
- Kidney impairment: The kidneys have to work harder to remove excess sodium, which can lead to chronic problems over time.
- Calcium loss: A high salt intake can cause the body to eliminate more calcium than necessary, promoting the development of osteoporosis.
- Brain disorders: Excessive salt consumption has been linked to an increased risk of dementia and other cognitive problems in older age.
Despite these risks, reducing salt intake doesn't have to be difficult. There are effective strategies for limiting your daily salt intake without sacrificing the flavor of your food.
The recommended daily amount of salt
The World Health Organization (WHO) states that adults should consume no more than 5 grams of salt per day , which is equivalent to one teaspoon. This amount includes all salt present in food, from processed foods to salt added during preparation.
For children aged 2 to 15, a smaller amount is recommended, adjusted according to their age, weight, and physiological needs. Furthermore, all salt consumed should be iodized, as iodine contributes to healthy brain development and prevents problems such as hypothyroidism or goiter.
In some cases, such as for people with high blood pressure , pregnant women, or older adults, doctors may recommend even more restricted consumption. It is essential to consult a healthcare professional to determine an appropriate amount for each individual case.
Hidden salt in processed foods
We often underestimate the amount of salt we consume because it's not only present in the salt we add to our food, but also in large quantities in processed foods . According to recent studies, more than 70% of the sodium we ingest comes from these products.
Foods like processed meats , canned goods, cheeses, breads, commercial sauces, and fast food often contain high levels of sodium as a preservative or to enhance their flavor. Checking nutrition labels can help us identify products with low sodium content.
For example, a serving with more than 400 mg of sodium is considered high in salt. Conversely, choosing low-sodium or no-salt-added versions is an excellent way to reduce your overall intake.
Tips to reduce salt intake
Reducing salt consumption does not mean giving up flavour in our meals. Here are some practical tips:
- Avoid using the salt shaker: Instead of adding salt at the table, use aromatic herbs or spices such as oregano, thyme, basil o pepper to enhance the flavors.
- Opt for fresh food: Fresh fruits, vegetables and meats contain less sodium than processed foods.
- Read the labels: Look for products labeled “low sodium” or “no salt added.”
- Cook at home: Preparing food from scratch gives you greater control over the amount of salt you add.
- Use alternatives: Replace salt with lemon juice, vinegar or garlic to add a tangy or spicy touch to your dishes.
Adopting healthy salt habits can have a significant impact on your overall well-being. Adjusting your daily salt intake to medical recommendations and opting for healthier alternatives is a crucial step in preventing disease and improving your quality of life.
