“Myelin plays a crucial role in the human body’s nervous system. It is essential for the efficient transmission of nerve impulses and overall nervous system function. Here are some pivotal functions of myelin in the human body:
- Nerve Insulation: Myelin serves as an insulating layer around nerve fibers or axons. This insulation is vital because it enhances the speed and efficiency of nerve impulse transmission. Think of it as similar to the insulation around electrical wires, if there will be no insulation around the wire than current can leak out and you may experience electric shock in the same fashion this myelin is preventing signal loss and enabling rapid communication along the nerve fibers.
2. Protective Function: Myelin also acts as a protective shield for nerve fibers, helping shield them from damage and preventing cross-talk between neighboring nerve fibers.
3. Metabolic Support: The cells responsible for forming myelin, called oligodendrocytes in the central nervous system and Schwann cells in the peripheral nervous system. They supply essential nutrients and contribute to the overall health and maintenance of axons.
4.Disease and Dysfunction: Disorders affecting myelin, such as multiple sclerosis, can disrupt the normal functioning of the nervous system.
In summary, myelin is a critical component of the nervous system, enabling swift and efficient communication between different parts of the body while also safeguarding nerve fibers from harm. Dysregulation of myelin can lead to significant neurological issues and diseases.”
In a nutshell myelin is very important for a human body to run as it is directly related with the functioning of nervous system and allows the rapid and smooth communication between the different parts of body. As earlier said it is very important lets understand that which nutrient can help you to maintain the myelin as if this reduces it can also lead to amnesia.
Lets first understand what it is made up of as it will be requiring the same raw material for its maintenance
Myelin sheath is made up lipids/fats whatever you want to call it you can as fats and lipids are same can be used interchangeably. The high lipid content of myelin is essential for its insulating properties and prevents the information loss and allows nerve impulses to move swiftly.
Maintenance: As we just learned that it is made up fat so, it will be needing the same raw material i.e. dietary fats in adequate quantity to maintain it.
Nutrient Transport: Fats also play a role in transporting essential fat-soluble vitamins, such as vitamin D and vitamin K, which are important for overall nerve health. These vitamins are necessary for various cellular processes, including those involved in maintaining myelin sheath health.
This may astonish a large chunk of population when they will come across this statement that fats is very much required for maintenance and repair of myelin sheath but this is true and it’s a physiological fact, scientific truth or you can also say it is an universal truth which no one can deny. When wwwe talk about the composition of myelin sheath we just learned that it is made up of fat but the major fat component or class of lipid which is contributing to it is the one from which everyone is scared, lets reveal the name.
The 1st class of lipid is “Cholesterol” yes you heard it right and believe e there is no mistake in listening to this. Cholesterol from which everyone is scared as it is having a bad reputation with respect to lipid profile in body, heart blockage (Atherosclerosis is the buildup of fats, cholesterol and other substances in and on the artery walls) and various other problems but don’t worry and just take a deep breath of relaxation now the U.S. Dietary guideline has been evaluated and the barrier on dietary cholesterol has removed as there is no enough cholesterol coming from diet.
So this cholesterol is playing a pivotal role in maintaining your neural health but along with this there is other fat as well and that is the essential fatty acids Omega-3 which your body cannot make.
So when you consume omega-3 from fish oil you get a direct derivative called EPA
Eicosapentaenoic acid and Docosahexaenoic acid (DHA). EPA is anti – inflammatory but when it come s to brain health DHA is very important.
It has been found in researches if you are taking DHA and leading an active lifestyle then the combination of EPA and DHA can be consumed up to 1gm to 1.5gm but when it come to myelin sheath and DHA dosages then it has been seen that the sole dosages of DHA up to 2 gm per day are enough to prevent brain from any injury.
So myelin is related to nerve impulses your reflex actions and memory and if it is not health then a person may encounter diseases like amnesia, dementia, Alzheimer’s and many more hence if you really want your brain to be healthy then there should be adequate fat in your diet and this must include animal based foods, dairy products, cashews, macadamias, almonds. These are ours recommendations this may vary from person to person and their allergies.
