Dietary Salt Intake Survey

Overview

High dietary salt intake is recognised worldwide as a major modifiable risk factor for hypertension, cardiovascular disease and stroke. While publichealth agencies recommend limiting sodium to less than 2g per day (about 5g of salt), many populations regularly exceed this amount.

This survey was conducted to capture current salt consumption patterns, identify major food sources of sodium, and evaluate public awareness of dietary guidelines across diverse demographic groups.

Methodology

Study Design

A crosssectional questionnaire was distributed online and in community centres between January and March 2026. A total of 4,200 respondents aged 1875 completed the survey.

Data Collection

• Selfreported daily salt use (teaspoons, packets, and added during cooking).
• 24hour dietary recall for a subsample of 800 participants.
• Knowledge assessment (five true/false statements about recommended intake).
• Demographic information age, gender, region, education, and health status.

Statistical Analysis

Descriptive statistics summarise consumption levels. Logistic regression evaluates the association between high salt intake (>5g/day) and variables such as age, BMI, and awareness of guidelines.

Key Results

Overall Consumption

Average selfreported intake was 8.4g of salt per day (SD=3.2g). Only 12% of participants reported consumption within the recommended limit.

Major Sources of Sodium

Awareness of Recommendations

Only 38% correctly identified the maximum recommended daily salt intake. Awareness was highest among respondents with a university degree (55%) and lowest among those with secondary education only (24%).

Health Impact of Excessive Salt

Excessive sodium increases blood volume, leading to higher arterial pressure. Longterm effects include:

• Elevated risk of hypertension a 2gram increase in daily salt raises systolic BP by ~2mmHg.
• Greater likelihood of cardiovascular events such as myocardial infarction and stroke.
• Kidney damage and accelerated progression of chronic kidney disease.
• Potential contribution to gastric cancer via mucosal irritation.

Populationlevel reductions in salt intake have been shown to avert thousands of premature deaths each year.

Recommendations for Policy Makers and Individuals

PolicyLevel Actions

1. Set mandatory sodium targets for processed foods and restaurant menus.
2. Introduce frontofpack labeling that highlights highsalt products.
3. Launch publichealth campaigns using clear, culturally relevant messages.
4. Encourage reformulation incentives for manufacturers.

Community & Household Strategies

• Use a pinch of salt (0.5g) when cooking instead of the full teaspoon.
• Season foods with herbs, citrus, or spices as alternatives.
• Read nutrition labels aim for 130mg sodium per 100g.
• Prefer fresh or frozen vegetables over canned varieties that contain added salt.

Individual Monitoring

Track daily intake using a mobile app or food diary. For people with hypertension, a goal of 5g of salt per day is advisable.
