    “A Physician Should Never Tell A Patient To ‘Cut Back On Salt’…This Causes Higher Insulin & Higher Blood Pressure.”

    Salt Is The 2nd Major Constituent In The Body & We Need Salt At All Times.

    When salt intake is restricted, the body activates hormonal systems to retain sodium & cause insulin resistance:

    🛞 Activation of the renin-angiotensin-aldosterone system (RAAS): Restricting sodium causes the body to release hormones like renin, aldosterone & angiotensin II to help retain sodium. This increases insulin resistance.

    🛞 Increased stress hormones: Low sodium intake increases the body’s levels of stress hormones, such as noradrenaline. Elevated levels of these hormones cause insulin resistance.

    🛞 Reduced blood flow to muscles: A drop in blood volume due to sodium restriction reduces blood flow to skeletal muscles. This impairs the delivery of insulin & glucose to muscle tissue, worsening insulin resistance.

    🛞 Increased insulin levels: The body responds to salt restriction by increasing fasting insulin levels as a compensatory measure to retain sodium. This is a risk factor for developing type 2 diabetes.

    5 Ways Insulin Resistance Causes High Blood Pressure:

    🛞 Sodium & water retention: When insulin resistance occurs, the pancreas produces excess insulin to manage blood sugar. The high levels of insulin overstimulate the kidneys to reabsorb more sodium & water, which increases blood volume & raises blood pressure.

    🛞 Vascular dysfunction: Healthy insulin signaling promotes the production of nitric oxide (NO), a molecule that relaxes blood vessels & improves blood flow. In an insulin-resistant state, this process is halted & blood pressure rises to dangerous levels.

    🛞 Increased sympathetic nervous system activity: High insulin levels overstimulate the sympathetic nervous system, which controls the body’s “fight or flight” response. This increases heart rate, constricts blood vessels & activates the RAAS system, which further promotes sodium & water retention.

    🛞 Chronic inflammation & oxidative stress: Insulin resistance causes low-grade chronic inflammation & oxidative stress throughout the body. These processes damage the lining of blood vessels (the endothelium).

    🛞 Vascular stiffening: Over time, the chronic inflammation & other issues leads to arterial remodeling & stiffening. This makes arteries less flexible & more resistant to blood flow, forcing the heart to pump harder & elevating blood pressure.

    From an interview with Dr Ben Bikman, PhD.

    Salt is not created equal….table salt is highly processed & toxic. Healthy salt is unrefined mineral salt…unprocessed celtic or grey salt that retains all of the 80+ trace minerals.
