Foods to Eat for Healthy and Smart Brain



" To keep the body in good health is a duty, otherwise we shall not be able to keep our mind strong and clear." - Buddha


Introduction

The brain is the control center of the body. It is in charge of keeping the heart beating, lungs breathing, and allowing us to move, feel, and think. it works 24/7 even when we are asleep and hence requires a constant supply of fuel. This fuel comes from the food we eat. The foods that we eat play an important role in keeping the brain healthy and smart. Our brain will function the best when we put the best fuel in it. This means that we need to eat an excellent quality foods which contain vitamins, minerals, nutrients, and anti oxidants which nourishes our brain. As we age, the body ages along with us and so does the brain. In order to increase the chances of maintaining a healthy brain, we need to eat the right and smart foods.


Foods to eat for a healthy brain

Foods to Avoid to keep the brain healthy:

In order to keep the brain healthy and smart, it is necessary to know the foods to avoid along with foods to eat so that brain health can be improved.

The foods to avoid to keep the brain healthy are:


Sugary drinks

Excessive intake of sugary drinks like soda, energy drink, sports drink, etc. have adverse effects on health. Along with this, higher sugar levels in the blood increase the risk of dementia, reduction in brain function, learning, memory, and formation of brain neurons. Diet high in sugar increases brain inflammation and memory impairment.



Refined carbohydrates

Refined carbohydrates include sugars and highly processed grains. These types of carbohydrates usually have a high glycemic index (GI) and glycemic load (GL). Foods with high GI and GL impair brain function and memory in both children and adults. Studies also showed that a higher intake of fat and refined sugar results in poorer memory. It also leads to mental impairment and dementia in older people.


Trans fatty foods

Trans fat foods are unsaturated foods which cause a harmful effect on the brain. Natural trans fats do not have adverse effects but artificial trans fats are found to increase the risk of Alzheimer's disease, poorer memory, lower brain volume, and cognitive decline.


Processed Foods

Highly processed foods contain high sugar, added fats, and salt. These foods are usually high in calories and low in nutrients which leads to weight gain. This weight gain has a negative effect on the brain. Increased fat is associated with brain tissue damage. The factors like lower levels of sugar metabolism and brain tissue damage mark Alzheimer's disease. Processed foods reduce the production of a molecule called a brain-derived neurotrophic factor, which is important for long-term memory, learning, and growth of new neurons. Therefore reduction of these molecules leads to a negative impact on the brain.


Aspartame

Aspartame is an artificial sweetener. This has been linked to behavioral and cognitive problems. It is made of phenylalanine, aspartic acid, and methanol. Phenylalanine crosses the blood-brain barrier and disrupts the production of neurotransmitters. It is a chemical stressor and increases the brain's vulnerability to oxidative stress. A study showed that people consuming aspartame had higher levels of irritability, depression, and performed worse on mental tests. Another study showed an increased risk of stroke and dementia. Long term intake of aspartame leads to an imbalance in antioxidant status in the brain.


Alcohol

Alcoholism results in a reduction of brain volume, metabolic changes, and disruption of neurotransmitters. People consuming alcohol have a deficiency in vitamin B1 which can lead to a disorder called Wernicke's encephalopathy which in turn develops into Korsakoff's syndrome. This syndrome causes severe damage to the brain including memory loss, eyesight problem, confusion, and unsteadiness. Teenagers who drink alcohol have abnormalities in the structure, function, and behavior of the brain.


Mercury rich foods

The primary food source for mercury in humans is seafood. High levels of mercury disrupt the central nervous system and neurotransmitters. It also results in damage to the brain due to the stimulation of neurotoxins. In fetuses and children, mercury can disrupt brain development and cause destruction of the cell components leading to cerebral palsy and other developmental delays.


Soya Sauce

According to a hypertension journal, sodium packed foods like soya sauce restricts blood to the brain and negatively impacts focus, organizational skills, and memory.


Ice cream

Ice-cream has artery-clogging saturated fat and high levels of sugar. The saturated fat and sugar-rich diet can diminish cognitive skills and verbal memory.


Foods rich in sodium

High levels of sodium in the blood increases the salt content in the body. It reduces the blood flow in the brain and impaired cognition. People with high levels of sodium have difficulty in recognizing objects, imbalance in the body. A study on mice fed with sodium-rich food showed an accumulation of protein in the brain which was linked with Alzheimer's disease and other dementias. There may also be a risk factor for declining brain function with age.


Many other substances in food are also dangerous to the brain. Out of all the foods listed above, alcohol causes huge damage to the brains and high levels of mercury permanently damage the brain. However, it is not necessary to avoid these foods completely as some of these foods contain other nutrients essential for the body.


Conclusion:

In general, the brain requires proteins, Vitamin B, vitamin C, vitamin E, omega 3 fatty acids, carbohydrates, antioxidants, proteins, and caffeine to keep the brain healthy and smart.

Apart from all these brain require water. Water plays an important role in making the brain healthy and smart. It helps to keep our body and brain healthy, fit, and fine. The best thing to do to keep our brain and body healthy is to eat fresh, healthy, nutrient-rich, and whole foods. Exercise is also a must to keep our brain healthy and smart.

"The brain is the man, its health is essential for normal living. Its disorders are surely the most profound of human miseries; and its destruction annihilates a person humanly, however intact his body." - Anonymous quote.
