A Finnish study reveals a link between sodium intake, the main component of salt, and obesity. Women appear to be particularly affected by this phenomenon.
Researchers analyzed data from over 5,000 Finnish adults. They found that high sodium intake was associated with an increased risk of general and abdominal obesity. This association was more pronounced in women, with risks multiplied by more than four.
The study is based on dietary questionnaires and urine analyses. Participants with the highest sodium intake showed significantly higher obesity rates. The results suggest that sodium may influence weight gain independently of calorie consumption.
The main sources of sodium in the Finnish diet are processed meat products, bread, and dairy products. The authors emphasize that these common foods contribute significantly to excess sodium, often overlooked by consumers.
The biological mechanisms behind this association remain to be clarified. Researchers point to hormonal disruptions or changes in the gut microbiome. These hypotheses require further investigation to be confirmed.
The study calls for dietary reform involving the food industry. The authors believe that changes in product composition are necessary to reduce sodium consumption at the population level.
Finally, researchers stress the importance of continuing research. Understanding the exact role of sodium in obesity could open new avenues for preventing and treating this complex disease.
