A research project from Tulane University has established a correlation between the frequent addition of salt to food and an increased likelihood of developing Type 2 diabetes, emphasizing the importance of salt moderation as a preventative strategy. The research, involving over 400,000 subjects, identified an increase in risk by as much as 39% among those regularly consuming salt, underlining the advantages of a diet low in sodium for reducing the chances of diabetes onset.
The association between habitual salt consumption and Type 2 diabetes has been confirmed for the first time.
For individuals prone to Type 2 diabetes, the conventional wisdom has been to limit sugar intake, but recent findings recommend they should also consider reducing salt intake.
The study carried out by researchers at Tulane University and reported in the “Mayo Clinic Proceedings” journal, indicates a connection between the regular addition of salt to foods and a heightened risk of Type 2 diabetes.
Details of the Study and Its Consequences
Over 400,000 adults from the UK Biobank provided data regarding their salt consumption habits. During a follow-up period averaging 11.8 years, over 13,000 participants developed Type 2 diabetes. Those who added salt “sometimes,” “usually,” or “always” were found to have a 13%, 20%, and 39% increased risk of the condition, respectively, compared to those who seldom or never used additional salt.
Link to Other Health Concerns
“Cutting back on salt is already associated with a reduced risk of cardiovascular diseases and hypertension. However, this study presents new evidence that reducing salt can also lower the risk of Type 2 diabetes,” remarked Dr. Lu Qi, the study’s lead investigator and a professor at Tulane University’s School of Public Health and Tropical Medicine.
While the study establishes a link, further investigation is needed to understand why high salt intake may lead to a greater risk of Type 2 diabetes. Dr. Qi speculates that high salt may stimulate overeating, thus increasing the likelihood of obesity and inflammation—conditions that are recognized risk factors. Frequent salt consumers also showed higher body mass index (BMI) and waist-to-hip ratios.
Dr. Qi advocates for a clinical trial to monitor and control salt intake among participants to observe direct effects.
In the meantime, Dr. Qi advises beginning the search for alternatives to high-sodium seasonings for food.
Making this adjustment may be simple, but Dr. Qi stresses its potentially significant benefits for one’s health.

Frequently Asked Questions (FAQs) about Salt Intake Diabetes Risk
Does frequent salt addition to food increase the risk of Type 2 diabetes?
A study from Tulane University, published in “Mayo Clinic Proceedings,” found that regularly adding salt to food is associated with a significant increase in the risk of developing Type 2 diabetes. Data collected from over 400,000 participants showed that regular salt consumers had up to a 39% higher risk compared to those who rarely or never added salt to their food.
How does excessive salt intake relate to Type 2 diabetes?
The study suggests that high salt intake may lead to behaviors that increase the risk of Type 2 diabetes, such as overeating, which can result in obesity and inflammation—known risk factors for the disease. Those who frequently consume salt also exhibited higher BMI and waist-to-hip ratios, which are associated with the development of diabetes.
What were the key findings of the salt intake and diabetes study?
Researchers observed that individuals who “sometimes,” “usually,” or “always” added salt to their food had a respectively 13%, 20%, and 39% higher chance of developing Type 2 diabetes than those who did not add salt regularly. This correlation underscores the need for public health strategies to reduce salt consumption.
Why is it important to understand the link between salt intake and diabetes?
Understanding this link is crucial for public health as it identifies a modifiable dietary habit that can help prevent the onset of Type 2 diabetes. It also adds to the body of knowledge connecting diet to chronic diseases, which is vital for creating effective dietary guidelines.
What are the implications of this study for people at risk of Type 2 diabetes?
The findings suggest that individuals at risk of Type 2 diabetes should consider moderating their salt intake as part of their dietary management. Reducing salt could serve as a preventive measure alongside other lifestyle modifications, such as improving overall diet quality and increasing physical activity.

wow so salt’s the new bad guy huh always knew we were using too much gotta rethink my recipes now…less salt more herbs perhaps
interesting findings from Tulane never thought salt could have such an impact on diabetes its always been about sugar right
so its not just my investments that need diversifying, gotta mix up the diet too much salt seems like a bad bet now
just read the article on salt and diabetes risk sounds serious but can we really cut down salt that much flavor matters too doesnt it
this study is a wake up call for many, we really gotta pay attention to what we put on our plate not just sugar but salt too
