The Way To Brain Health Is Through Your Gut; Brain Foods To Add To Your Diet

Debilitating brain diseases are on the rise, from ADHD and autism in the younger progeny to Dementia, multiple Sclerosis and Alzheimer’s in the older generation. Even middle aged individuals are prone to age old diseases before their time. A paradigm shifting medical revolution, led by Dr Perlmutter, has unearthed evidence that the health of our brains is largely ruled by the health of our gut. What’s going on in our gut today defines what will happen to our brains tomorrow. A healthy digestive system paves way for a sharper brain. Those who eat smart brain foods, work smart.

Contrary to the common belief, our body has two nervous systems- the central nervous system, comprised of the spinal cord and brain, and the enteric nervous system which is ruled by the gastrointestinal system. Perlmutter says that our gut is a second brain and our happiness depends upon its health.

Our gut is colonized by trillions of microbes with whom we live symbiotically; a striking ratio of 10:1 of our cells. Microbes are developed in the human body by birth and are mostly ingested through breast feeding. How they evolve is dependent on our dietary choices. Providing a suitable environment to let the microbes flourish is essential for fundamental processes in the body, including cognitive abilities, production of neurotransmitters like serotonin and dopamine, immunity and expression of DNA.

In-depth exploration of our body’s micro biome reveals correlation between them and an array of brain disorders such as Parkinson’s disease, Celiac disease, Alzheimer’s, Dementia, depression, anxiety and many others. Our diet and lifestyle have a profound effect on the development of micro biome and will affect our health. 90% of our DNA is contained inside the gut probiotics microbes and thus they determine the health of our mind and body.

Healthy gut bacteria are fostered by a balanced diet, active lifestyle and breast feeding and are easily destroyed by a Vitamin B12 deficiency, chlorinated water, antibiotics and junk food. Our brain thrives on the health of gut bacteria. Here’s a list of brain foods that you can incorporate in your daily meal to nurture a healthy microbe colony:

In addition to an alteration in dietary habits, keeping yourself well hydrated is indispensable to gut health. To protect the micro biome colony, cultivating in your gut, avoid drinking tap water as it often contains chlorine. Chlorinated water is detrimental to microbe environment and therefore you should switch to mineral or filtered water.


We run towards the neighborhood clinics for the smallest of infirmity such as common cold and fever and are administered with a dose of broad spectrum antibiotics. Being broad spectrum they wipe out the good gut bacteria along with the bad one.

The gut microbes protect the lining of the gut and reduce permeability. This in turn reduces the risk of inflammation in our bodies.  Over use of antibiotics and environmental toxins alters the microbes and damages the integrity of the gut lining. Inflammation is the culprit underlying major diseases such as Alzheimer’s, dementia, diabetes and cancer. Understanding the need to protect the gut bacteria and the pivotal role it plays in our health, would go a long way in the cure of devastating neurological diseases.

Mediterranean diet is mainly composed of seafood, fruits, vegetables, nuts, whole grains and olive oil; foods that ward off diabolical diseases such as diabetes, coronary diseases, cancer and cognitive decline. A strong adherence to an anti inflammatory Mediterranean diet is linked to increased cognitive function, lower risk of Alzheimer’s disease and slowed decaying of the brain functionalities. Making the switch from the sumptuous and addictive junk food to a healthier alternative might take a little effort but is all the difference between life and death!

The importance of the gut-brain relationship is giving birth to striking experimentation. A growing body of evidence links the Mediterranean diet, rich in antioxidants, like berries and fruits, to improved brain functions. Free radicals wreak havoc on our brain and the antioxidants found in these food groups helps to combat them and also prevent neurodegeneration and ageing of brain. In addition, cutting back on sugars, fried foods, red meat and carbohydrates plays an important role in maintaining the gut brain health.

Consuming olive oil and nuts contribute to brain health since they contain Polyphenols. Polyphenols prevent oxidation and inflammation, both of which are detrimental to blood vessels in the brain. Our brain is an oxygen hungry organ and clogged blood vessels eventually lead to destruction of brain cells. Polyphenols are also found in plant based brain foods such as berries, tea and spices like curcuma.


Mediterranean diet is rich in brain foods. If you are new to a Mediterranean diet, here are a few tips for you to get started:

  • Stock up on vegetables: Veggies are the ultimate brain foods. be it a simple salad of cherry tomatoes tossed in olive oil and feta cheese, or a vegetable pizza loaded with fresh greens instead of destructive pepperoni and sausage, vegetable soups or simply veggie sides with your favorite meal at a restaurant.
  • Cut back on meat: if you are meat lover, it’s time to reconsider your dietary choices. If you must eat, try reducing proportions and switch to leaner cuts. One way to incorporate meat in a healthy dish is to add chunks of chicken or fish to a leafy salad for added taste.
  • Never Skip on Breakfast: one of the worst mistakes of people is to skip breakfast when pressed for time. Eat fruits, breakfast cereals, whole grain wheat or fiber rich foods to kick start the day in a healthy way. It will also induce fullness for long and curb calorie craving.
  • Eat more Seafood: omega 3 fatty acids rich sea foods such as fish, shell fish, tuna, herring, salmon, sardines and oysters are to be consumed at least twice a week. One way to put up a delectable hearty meal is to grill fish with olive oil with a serving of green beans on the sides.
  • Eat Good fats: Good fats such as olive oil, nuts, olives, sunflower seeds, flax seeds and avocados are excellent for maintaining the gut health. Sunflower, soybean and corn oil are also a source of polysaturated fats.
  • Go Dairy: Try to incorporate brain foods such as yogurt, Greek yogurt, cheese and milk as part of your daily diet. Make sure you only choose the low fat dairy products from the counter.

Out Diet has a great influence on our gut microbia. A mixture of beneficial fatty acid profile, a high antioxidant intake, focus on poly and monosaturated fatty acids, and presence of high fiber low glycemic index food substances are characteristics of this diet. Since we have established a direct link between gut and brain health, let’s see how a Mediterranean dietary style, rich in brain foods, is good for the gut:

Carbohydrate and digestion:   The cumbersome nature of carbohydrates is a nuisance which is the leading cause of obesity in the world. Our body is not adapted to digesting high intake of polysaccharide molecules. By cutting back on carbohydrate rich food, you are more prone to maintaining a healthy weight and gut microbia health.

Increased Fiber consumption: Decreasing sugar and cholesterol absorption in the gut, the production of photochemical and other bioactive compounds, as well as anti-inflammatory properties have been proposed as processes involved in the healthy properties of fiber. Fermentation of fiber by the colony of gut microbes releases phenolic compounds which have anti oxidant and anti inflammatory properties.

Excellent source of antioxidants:   Mediterranean diet comprises of fresh fruits which are rich in antioxidants. A research has proven that eating fresh fruits greatly increases the accumulation of Lactobacilli and bifidobacteria, both of both are associated with maintaining gut health.

Fat Restricted diet: In addition to maintaining a healthy weight, a diet rich in fat nurtures a healthy environment for the growth of Lactobacilli and bifidobacteria. A high fat diet is also linked to increased risk of obesity related gut wall permeability and thus inflammation. There is in fact reason to believe that a diet limited in fat indeed
