In Cholesterol

It’s so important that only approximately 20% of cholesterol comes from the food we eat and the liver makes the rest to ensure we always have adequate levels. Here’s why cholesterol is good for us:

  1. Cell Structure and Function: Cholesterol is a vital component of cell membranes, the outer layer surrounding every cell in our bodies. It helps maintain the integrity and fluidity of cell membranes, allowing cells to communicate with each other, transport nutrients and waste products, and perform their specific functions effectively. Without cholesterol, our cells wouldn’t be able to function properly, and our bodies wouldn’t be able to carry out essential processes.
  2. Hormone Production: Cholesterol serves as a precursor for the synthesis of various hormones in the body, including cortisol, estrogen, progesterone, and testosterone. These hormones are critical in regulating metabolism, reproductive function, stress response, and other physiological processes. Without cholesterol, our bodies wouldn’t be able to produce these hormones, which are essential for maintaining overall health and well-being.
  3. Vitamin Synthesis: Cholesterol is necessary for the synthesis of vitamin D, a fat-soluble vitamin that plays a crucial role in bone health, immune function, and other physiological processes. When sunlight hits our skin, cholesterol in the skin cells undergoes a chemical reaction, leading to the production of vitamin D. Without cholesterol, our bodies wouldn’t be able to synthesise vitamin D efficiently, potentially leading to deficiencies and health problems.
  4. Bile Production: Cholesterol is a key component of bile, a digestive fluid produced by the liver and stored in the gallbladder. Bile helps emulsify fats in the digestive tract, making them easier to absorb and transport. Without cholesterol, our bodies wouldn’t be able to produce an adequate amount of bile, leading to difficulties digesting and absorbing dietary fats and fat-soluble vitamins.
  5. Brain Function: Cholesterol is abundant in the brain, where it plays essential roles in neuronal signalling, neurotransmitter synthesis, and the formation of synapses (connections between nerve cells). Adequate cholesterol levels are crucial for maintaining cognitive function, memory, and overall brain health. Low cholesterol levels have been associated with an increased risk of cognitive decline and neurological disorders.
  6. Wound Healing: Cholesterol is involved in the process of wound healing and tissue repair. It helps stabilise cell membranes, supports immune function, and promotes the formation of new blood vessels, all of which are essential for the healing process. Adequate cholesterol levels ensure that our bodies can effectively repair damaged tissues and recover from injuries.

In summary, cholesterol is not inherently bad; in fact, it’s essential for various aspects of our health and well-being. From cell structure and hormone production to brain function and wound healing, cholesterol plays numerous vital roles in the body. Rather than demonising cholesterol, it’s essential to understand its role in the body and what underlying factors may be causing imbalances – such as inflammation, digestive dysfunction or genetics.
