As the World Salt Awareness Week shines in the spotlight in the dietary sodium, it is time to question the long -term narrative that salt is the primary villain in the history of hypertension and cardiovascular disease. Unlike the decades of public health messages, recent high quality research suggests that our focus on reducing salt intake can be incorrect direction. Instead, we should carefully consider processed foods, sugar and insulin resistance, the real cause behind hypertension and cardiovascular disease

The myth of salt and hypertension
For years, the connection of disease with salt -blood pressure has been accepted as a stable science. Public health guidelines encouraged the drastic sodium restriction, often recommending levels as low as 1.5 grams a day. However, the evidence continues to increase this simplistic view.
In a critical review of the sodium -cardiovascular disease, Dinicolantonio et al. (2015) argue that data that supports sodium restriction to prevent cardiovascular disease is weak and inconsistent [1]. Many population studies, including those mentioned by Alderman et al. (2017), failed to show a clear benefit from reducing sodium in cardiovascular effects and in some cases low sodium intake was associated with increased mortality [2].
In fact, the report of the 2013 Medicine Institute (IOM) concluded that there is no consistent evidence that sodium intake below 2.3 grams daily leads to better health results, especially in people with diabetes, chronic kidney disease or pre -existing cardiovascular conditions. [3].
The true guilty: insulin resistance and metabolic dysfunction
If not salt, then what leads to the modern epidemic of hypertension and heart disease?
The answer lies in metabolic disorders caused by highly processed carbohydrate high -carbohydrate diets especially the development of insulin resistance. As discussed in a landmark BMJ open heart paper by Dinicolantonio and Lucan (2014), the focus should be shifted from sodium to sugar, which contributes more directly to hypertension through insulin effects, activating sympathetic nervous system [4].
Insulin resistance promotes sodium retention, increases sympathetic activity and leads inflammation that contributes to increased blood pressure [5]. According to Volek et al. (2018), ketogenic diets, which reverses insulin resistance, improve blood pressure, inflammation indicators and lipid profiles [6].
Review of Salt Recruitment: A J -shaped curve
Instead of being linear, the relationship between sodium intake and cardiovascular results follows a J -shaped curve. This means that both very low and very high sodium recruitment is associated with increased risk, while moderate intake between 3 and 5 grams daily is linked to the lowest risk [2,7].
Practical Recommendations: Sodium and metabolic health optimization
If you eat a diet of the whole food, ketogen or low carbohydrate, your salt requirements may be above from the general population. This is due to the fact that low insulin levels promote sodium excretion through the kidneys. In this context, increasing salt intake can prevent symptoms such as fatigue, headaches, dizziness and even pulse feeling.
General Guidelines for Sodium Recruitment on Ketogena Diet:
- Aim for 4-7 grams of salt daily (1.6-2.8 grams of sodium) for most healthy adults.
- Increase the intake during periods of sweating, exercise, fasting or initial KETO adjustment.
- Use rich in mineral salt (eg sea salt or Himalayan salt) when possible.
- Avoid extremely processed foods-these are the main coefficients in harmful sodium intake.
Salt is not the enemyy
The elements are clear: Salt mistreatment is outdated and unsupported by strong data. Instead, resistance to insulin, driven by high carbohydrate, processed diets, is the main cause of hypertension and cardiovascular disease in most people. As we observe the World Salt Awareness Week, let’s shift the debate away from the restriction of salt based on fear and metabolic health, real foods and nutritional interventions supported by science.
