The Gut-Brain Connection: Nurturing Your Microbiome for Brain Health and Disease Prevention

The gut microbiome consists of multiple microorganisms, like bacteria, viruses, and fungi, that live in the human gastrointestinal tract, mostly in your large intestine. They are important to us due to their role in digestion, metabolism, our immune systems, etc. The microbiome is responsible for breaking down complex carbohydrates, producing different kinds of vitamins that our body cannot synthesize, helping us absorb different nutrients and protecting us against harmful pathogens. Based on how well our body performs in these functions, we can be less likely to develop diseases like Alzheimer’s and Parkinson’s disease and prevent illnesses like depression and anxiety.

New emerging research in animals and humans shows there may be a ‘gut-brain axis’ in our body that functions like a bidirectional communication network between your brain and your intestinal microbiome. Simplified, it means that if you eat well, you’ll feel well and if you feel well, you’ll eat well.

The gut microbiome is a complex dynamic system, which results in multifaceted connections as to how it affects your brain health. An unhealthy gut can lead to inflammation, which affects the blood-brain barrier (resulting in toxic material entering your brain and contributing to neuroinflammation). It can also compromise your immune system, which has been known to contribute to neurological disorders like multiple sclerosis.

To protect your gut health, one should aim to follow three main steps:

1.      Eat more probiotics and prebiotics: Probiotics and prebiotics are beneficial bacteria and the food that these beneficial bacteria consume. Foods like yogurt, kefir, sauerkraut, kimchi and other fermented foods are good ways to get in your probiotics. Prebiotics to consume, include garlic, onions, leeks, chicory root and asparagus to feed the growth of these gut bacteria.

2.      Consume more fiber: Eating a high-fiber diet through whole grains, fruits, vegetables, legumes and seeds can reduce inflammation and promote gut health.

3.      Limit processed foods with high added sugars: Having high added sugar foods has shown imbalances in gut bacteria and can often lead to growth of pathogenic bacteria at fast rates in your intestines.

In conclusion, the gut microbiome is a deeply complex ecosystem of microorganisms that need to be nurtured through various dietary choices to ensure that we can prevent brain disease in a world where brain disease is becoming ever so common.

The top 4 diets for PCOS: DASH diet, high protein diet, reduced calorie diet, and the keto diet. Which is better?

 PCOS is a  condition wherein people have imbalanced hormone levels. These imbalances present themselves in the form of polycystic ovaries, chronic irregular periods, and higher levels of testosterone in the form of increased body/facial hair. Among people who have PCOS, 80% of patients will hold fat around their belly and gain weight because of the effects of hormonal imbalances on their bodies. These effects include insulin resistance, gut dysbiosis, low-grade inflammation and more.  To treat this weight gain, doctors tend to recommend different diets to PCOS patients. But, the efficacy of these diets are heavily dependent on the person's individual situation. There are four major dietary approaches used to lose weight for people with PCOS: Reduced calorie diets, DASH diets, high protein diets, and keto diets. For most people, a combination of all of these diets will work best.  Here's a short explanation of each of these diets:  1) Reduced calorie diet: You e...

Eliglustat for Gaucher disease: How does it work? How is it consumed? Side effects? Is it safe? Efficacy? Research? Evidence?

Gaucher disease is a rare genetic disorder wherein the body lacks the ability to break down a specific kind of fat, which leads to accumulation thereof around various parts of the body, such as organs and bones. Eliglustat is one of the most common medications prescribed to help treat the disease by reducing production of the fat itself.  The disease is an inherited lysosomal storage disorder which is caused by an enzyme deficiency, specifically a low level of glucocerebrosidase. This enzyme breaks down a fat with a similar name, glucocerebroside. When the body lacks production of the enzyme, the fat accumulates around and in cells of the spleen, liver, and bone marrow. This causes a variety of symptoms in patients, and can present itself in bizarre ways like: enlarged spleens and livers, increased bone pain and occurrence of fractures, fatigue, anemia and even increased bruising.  Eliglustat, the medicine provided to patients, works in one way: substrate reduction. Basically,...

How does oxymetazoline work to clear your nasal passages?

Oxymetazoline Hydrochloride is a topical nasal decongestant that is often found in most OTC nasal sprays like Otrivin in India. It works quite effectively with regards to relieving people from nasal congestion caused by things like colds, allergies, or sinusitis by constricting blood vessels in the nasal passages. The medication is an alpha-adrenergic receptor binder, meaning that it binds to the alpha-adrenergic receptors. These receptors are found on the smooth muscle cells which line blood vessels in the nasal mucosa. When oxymetazoline is applied to the nasal mucosa through droplets, it stimulates the receptors and triggers them to cause constriction of nasal blood vessels. Through vasoconstriction, there is a reduce in blood flow to the region, causing decreased swelling and inflammation. It also reduces how much mucus is produced, since it reduces the quantity of fluid that leaks into the passages. Thus, air can flow more freely in the passage, providing relief from the blocked n...
