In short (click here for detailed version)

It is essential to limit salt intake to prevent cardiovascular diseases because high salt consumption is associated with high blood pressure, a major risk factor for heart diseases and strokes.

Relationship between salt and high blood pressure

When you eat too much salt, your body retains more water to maintain internal balance. This extra water increases blood volume, thereby exerting a stronger pressure on your arteries: this is what we call high blood pressure. In the long term, too much salt strains your heart, forcing it to work harder to pump all that extra blood. Gradually, your arteries become less elastic and more rigid, further increasing the risk that this higher pressure will damage your cardiovascular system. A regular excess of salt, even if it seems harmless in daily life, thus discreetly but surely promotes the development of hypertension, with all its health consequences.

Cardiovascular consequences of excessive salt intake

Too much salt forces your body to retain more water to compensate for this excess. As a result, it increases blood volume and, consequently, blood pressure. Consistently high blood pressure fatigues your heart, which then has to work much harder. Over time, this overexertion can lead to serious problems such as heart failure, the onset of heart rhythm disorders, or even increase the risk of a stroke or a heart attack. In short, abusing salt is giving your heart troubles it would rather do without.

Nutritional recommendations to reduce salt intake

To easily reduce your salt intake, limit your consumption of processed foods, such as prepared meals, cold cuts, or snack biscuits: they are loaded with hidden salt. Change your habits by favoring fresh or homemade products, where you control the amounts yourself. Replace salt with spices or herbs to enhance your dishes without feeling frustrated. Also, remember to check the nutritional labels: a product containing more than 1.5 g of salt per 100 g is already too salty. At the table, avoid having the salt shaker always within reach, which will prevent you from automatically adding more.

Cardiovascular benefits associated with reduced salt consumption

Reducing your salt intake is a small change that yields significant benefits for heart health. It significantly lowers the risk of high blood pressure, which is good for the entire cardiovascular system. Less salt also reduces the risks of strokes, heart attacks, and overall, it better protects your heart and arteries. You get tired less quickly, have more energy in your daily life, and it even helps keep your heart healthy for longer. A simple brake on the salt shaker today is a true winning strategy for your cardiovascular system in the long term.

Frequently Asked Questions (FAQ)

1

Are there any risks to abruptly stopping all salt consumption?

It is preferable to gradually reduce salt intake rather than eliminating it abruptly and suddenly. A too-rapid decrease can lead to a loss of appetite, a decrease in food enjoyment, or, very rarely, sodium balance disorders (hyponatremia). Ideally, adaptation should occur progressively over a few weeks.

2

Can we reduce cardiovascular risk by decreasing salt intake even in the absence of hypertension?

Yes, even if you don't have high blood pressure, limiting your salt intake can protect your cardiovascular system in the long term. Excessive reduction of salt helps preserve artery health, reduces the risk of future hypertension, and prevents heart and vascular diseases.

3

How much salt is it recommended to consume daily?

According to the World Health Organization (WHO), it is recommended to limit daily salt intake to a maximum of 5 grams (about one teaspoon). This corresponds to about 2 grams of sodium per day, which helps prevent the risks of hypertension and associated cardiovascular diseases.

4

What can I use to replace salt for flavoring my dishes?

To enhance your dishes without sugar or excessive salt, focus on using aromatic herbs (such as thyme, rosemary, basil), spices (like paprika, cumin, turmeric), garlic, onions, or citrus juices. These alternatives will add flavor and variety while preserving your cardiovascular health.

5

Sure! The translation of your sentence is: "What common foods contain a lot of salt without me necessarily knowing it?"

Processed foods, ready-made meals, charcuterie, and canned goods, as well as certain industrial breads and cookies, often contain a high amount of salt without necessarily tasting particularly salty. Getting into the habit of reading nutritional labels allows you to better manage your sodium intake.
