Eat Less Salt and Reduce High Blood Pressure Risk

You can eat less salt by using herbs, spices, and other flavor-enhancing methods, which is a tried-and-true method to lower blood pressure.

When people eat less sodium, a crucial component of salt, they experience a reduction in high blood pressure, one of the major causes of heart disease. Add other flavors to your cuisines, such as spices, herbs, aromatic roots (such as onions, garlic, and ginger), citrus, and vinegar, as a simple method to cut back on salt. Choosing items that are as fresh as you can, and employing the right cooking methods, are two other suggestions for enhancing flavor. Your dish will taste so great if you can blend these approaches that you will not want to add any more salt.

In fact, the World Health Organization (WHO) thinks that if we want to prevent chronic disease, we should all reduce our salt intake by 30% because it is assumed that too much sodium is unhealthy for the heart. The WHO also wants the same percentage reduction in cigarette usage.

According to the Centres for Disease Control and Prevention (CDC (Centers for Disease Control)), eating a lot of sodium may elevate blood pressure, which is a significant risk factor for heart disease and stroke.

The American Heart Association (AHA) also advises against exceeding 2,300 milligrams of salt per day. But is being aware that we need to consume less salt enough to enable us to do so? Not exactly. Cravings for salt are supported by a sophisticated brain process, some of whose components we are only now beginning to understand.

Researchers believe they have discovered a way to rig this neurobiological process, though, as eating hot foods appears to deceive our brain into not craving salty foods as much.

Previously, a pilot study indicated that trace levels of capsaicin, the molecule that gives chili peppers their strong fragrance, enhanced the perception of food being salty. Researchers wanted to explore whether this impact would also lower salt consumption.

Spicy foods may cause people to prefer less salt. As part of a multicentre, random-order, double-blind observational and interventional trial, the research team evaluated 606 Chinese adults. They looked at the participants’ preferences for salty and spicy flavors and discovered that those who valued spicy flavors more tended to consume less salt than those who valued spicy cuisine less.

Additionally, participants who enjoyed spicy flavors had lower systolic and diastolic blood pressures than those who chose salty tastes by 8 and 5 millimeters of mercury, respectively. The team supplied capsaicin to the subjects and then used imaging tools to look at their brain activity to investigate the effects that spicy food might have on the brain. They discovered that the orbitofrontal cortex and insula, which are affected by salt, were also active by the generated hot flavor.

The authors conclude that by altering the neuronal processing of salty taste in the brain, eating spicy meals can lower individual salt preference, daily salt intake, and blood pressure. They draw the conclusion that using spicy flavors may be a promising behavioral strategy for lowering high salt intake and blood pressure.

The study sample, as the authors acknowledge, was restricted to the Chinese population, so future research should look to see if these results hold true in other populations.

Governmental Dietary Advice

To lower blood pressure, health experts have long advised people to consume less sodium. Your body only requires 186 mg of sodium daily, according to estimates. However, it would be impossible to eat this little and still acquire the recommended amounts of other crucial nutrients. To prevent this, the Institute of Medicine (IOM) advises healthy persons to eat 1,500 mg (1.5 grams) of sodium daily. The US Department of Health and Human Services, the IOM, and the USDA all advise healthy adults to keep their daily sodium intake to under 2,300 mg (2.3 grams), or the equivalent of one teaspoon of salt. This upper limit was set based on data from clinical research showing that daily sodium intakes exceeding 2,300 mg (2.3 grams) can negatively affect blood pressure and raise the risk of heart disease.

These recommendations do not apply to persons who are extremely active, such as competitive athletes or outdoor workers, due to the higher salt loss through sweat.

Different recommendations are made by other groups.

The American Heart Association recommends a much lower intake of 1,500 mg (1.5 grams) of salt per day compared to the WHO’s recommendation of 2,000 mg (2 grams) per day.

Today, Americans consume 3,400 mg (3.4 grams) of sodium per day on average, which is far more than what health authorities recommend.

Should You Limit The Salt You Eat?

More than 7 grams of sodium per day is too much for people with high blood pressure, therefore they should limit their intake.

The same may be true if your doctor or registered dietitian has advised you to reduce your salt intake for health reasons, as in the case of a low-sodium therapeutic diet. However, for healthy individuals, reducing sodium intake does not seem to have much of an impact. Although health officials continue to advocate for lower salt diets, going below 3 grams daily may have detrimental effects on health.

According to studies, persons who drink less than 3 grams of salt daily run a higher risk of developing heart disease and dying young than those who consume 4-5 grams. An increasing body of research indicates that the existing sodium limits, which range from 1,500 mg (1.5 grams) to 2,300 mg (2.3 grams), may be too low. This raises questions about whether they are beneficial. However, the quantity of salt that healthy individuals are now consuming is safe, with only 22% of the population from 49 nations consuming more than 6 grams per day.
