A groundbreaking study published in the Journal of Metabolic Health has unveiled alarming connections between low-salt diets and systemic insulin resistance, posing significant health concerns. Drawing from 23 human clinical trials, the research reveals that these dietary regimens contribute to a spectrum of metabolic disorders, encompassing diabetes, cardiovascular diseases (CVD), polycystic ovary syndrome (PCOS), non-alcoholic fatty liver disease (NAFLD), and obesity.
“Ameet G Sattur, a renowned Consultant Interventional Cardiologist at Sattur Heart Care, explains, “Low-salt diets are indicated for some heart ailments and as a part of dietary restriction for patients with hypertension. They can trigger insulin resistance, elevating the risk of hypertension and increasing the risk of cardiovascular issues such as heart disease and stroke. While sodium restriction may lower blood pressure in some, it often leads to adverse metabolic outcomes. Twin Health’s tailored dietary plans consider individual metabolic responses, offering a safer and more effective approach to managing chronic conditions.”
The study highlights several mechanisms through which low-salt diets impact insulin sensitivity, including activation of the sympathetic nervous system, reduced skeletal muscle blood flow, and increased stress hormones like noradrenaline and aldosterone. These changes can lead to severe metabolic disruptions, making it essential to reassess the universal recommendation of low-salt diets.
“Maluk Mohammed, Co-Founder of Twin Health, adds, “Low-salt diets are linked to significant metabolic disruptions, but our Whole-Body Digital Twin technology can provide a solution. By analysing over 3,000 data points daily, we deliver personalised nutrition recommendations that balance macro, micro, and biota nutrients, ensuring better health outcomes.”
Clinical Dietitian and Diabetes Educator Kanikka Malhotra notes, “Low-salt diets are often recommended for lowering blood pressure (BP) but can have unintended consequences like worsening insulin resistance. This resistance leads to elevated blood glucose levels and weight gain. Twin Health’s personalised nutrition approach can help mitigate these risks by providing balanced, individualised diet plans.”
Insulin resistance occurs when the body’s cells become less responsive to insulin, leading to elevated blood glucose levels and a cascade of metabolic issues. It affects glucose regulation, lipid metabolism, and even mitochondrial function, contributing to conditions like non-alcoholic fatty liver disease and polycystic ovary syndrome.
As India grapples with rising rates of chronic metabolic diseases, the findings highlight the need for personalised nutrition strategies.
