Reducing salt intake by training the taste buds: healing practice

Reduce salt intake to lower blood pressure

A diet with too much Salt increases the risk of several health problems, including high blood pressure. However, many people have trouble reducing their salt intake. A new method of intervention aims to increase the preference for low-sodium foods and thus reduce salt intake and blood pressure.

In a recent study involving experts from university of kentucky examined the short-term effects of a new program for reduce sodium intake about him blood pressure and love for salty foods Has.

The results of the study were published in the ACNAP EuroHeartCare Congress 2022 presented, a scientific congress of European Society of Cardiology (ESC).

million deaths annually from high blood pressure

High blood pressure (hypertension) can, depending on the Robert Koch Institute (RKI) lead to cardiovascular disease and kidney failure and is considered one of the most important risk factors for mortality. are all over the world about 9.4 million deaths a year attributed to high blood pressure.

The most important risk factors for high blood pressure are lack of exercise, obesity, an unhealthy diet, stress and increased alcohol consumption. These lifestyle factors can be influenced, therefore, a high potential for prevention the illness.

A healthy diet protects against high blood pressure

One healthy nutrition Reducing the amount of salt consumed can contribute significantly to Protection against high blood pressure contribute. However, the benefit of reducing sodium intake on blood pressure has been shown to diminish over time. gradually decreases, the researchers report. This is due, at least in part, to poor adherence to dietary recommendations.

People consume too much salt for taste reasons.

One of the main barriers to following a low-salt diet is that people don’t like the taste, but few studies have addressed this issue.‘, explains the author of the study. Professor Misook Chung in a press release.

Program with a new approach to salt reduction

In the new research, a special program was carried out to reduce salt intake in 29 adults high blood pressure tried

Participants were randomly assigned in a 2:1 ratio to an intervention group or a group receiving usual care. The participants had an average age of 63, and 55 percent were men.

At the start of the study and again after a 16-week period, all participants provided a 24-hour urine sample to sodium intaketo determine e. In addition, blood pressure was measured.

In addition, the participants were asked to preference for salty foods rated on a ten point scale. This also applies to hers. Enjoying a low-salt diet. Changes in salt intake between groups were measured from baseline to the end of the study.

Usual care included routine medical and nursing care for hypertension. This includes the medication prescription and the recommendation that stakeholders low salt diet to retain.

In the intervention group, participants received training and follow-up in the form of video calls via a tablet for a period of 16 weeks. Sessions were held weekly for six weeks and then every other week for 10 weeks, the researchers said.

The one developed by the team. Sodium Watchers Program – Hypertension (SwaP-HTN) should lead to a gradual adjustment of taste to low-salt foods.

Program individually adapted to the participants

According to the researchers, the program was individually adapted to the obstacles and weekly objectives of the participants. These included shopping for salt, eating salt intake, cooking salt intake, shopping, and dining out.

How was the salt content of food determined?

To determine the salt content in food, participants were given an electronic device that was capable of to measure salinity. In this way, high-salt foods could be identified and avoided in the future, experts report.

Being able to assess your own salt intake

One of the first steps was for patients to recognize how much salt they were consuming. Using the electronic device, they could taste the salt content of restaurant meals and ask the chef to reduce or eliminate the salt content on their next visit.‘ explains Professor Chung.

The device was also used by the participants to Reduce salt levels in your own kitchen. For example, there were participants who automatically added salt to their food without tasting it first.

Most of the participants were reduced by only your salt intake for three weeks and no longer needed a salt shaker on the table, according to the study’s author.

30 percent less salt through intervention

Ultimately, the intervention actually led to a significant reduction in salt intake performed and participants in the intervention group would also have a greater enjoyment of a low-salt diet displayed.

In the intervention group, sodium intake decreased by 1,158 mg per day, a 30% reduction from baseline, while in the control group, daily intake increased by 500 mg“, how that Professor Chung.

Satisfaction with a low-salt diet increased in the intervention group from 4.8 to 6.5 on a 10-point scale, although participants still preferred salty foods.

No significant effect on blood pressure?

Mean systolic blood pressure in the intervention group tended to decrease from 143.4 to 133.9 mmHg, but the reduction did not reach statistical significance.

It is likely that the intervention did not result in a statistically significant decrease in blood pressure due to the small sample size.“, Explain chung.

Taste buds can be trained

Finally, the expert adds that the new study demonstrates how Taste buds trained on it can be low sodium to enjoy the food and gradually reduce the amount of salt you eat.

The gradual taste adjustment program has the potential to control blood pressure, but needs to be tested in a larger study with longer follow-up.“, how that Professor Chung. (What)
