What Does The Brain Do?

The brain is essentially the control system for the body and without it, your body basically wouldn’t work! The average adult brain weighs around 3 pounds and is responsible for a multitude of functions. This includes speech, memory, emotions, personality, behaviour, intelligence, language, sense of pain, organ function, body movement and the understanding of our senses. To do all that it takes a lot of energy and resources; in total, the brain requires around 20% of the blood and oxygen in the body and has over 100 billion neurons!

How Does The Brain Work?

Firstly, the brain receives information from our five senses: touch, sight, smell, taste and hearing. The brain then interprets these messages and creates meaning from them. It then tells the body how to react (such as whether to speak or move) and then stores the information in our short term memory. When we sleep, this information is then converted into our long-term memory.

The brain is also made up of 2 halves called the left and right hemispheres. These are responsible for different functions and control opposite sides of the body. The left hemisphere controls aspects such as writing, arithmetic, speech and comprehension whilst the right hemisphere controls aspects such as creativity, spatial awareness and musical skills. This is why there is a theory that people have a more dominant hemisphere that reflects your personality more and so you are either left or right-brained.

The brain is also part of the central nervous system along with the spinal cord. This is how the brain communicates with the rest of the body and receives and sends messages. It does this by using nerve cells called neurons which send chemical and electrical signals across pathways called synapses.

Symptoms of Poor Brain Health

A healthy brain can perform all these functions at optimum capacity, however, one that is not so healthy or is experiencing issues can lead to problems such as memory loss, speech impairments, strokes and even contribute towards illnesses such as Alzheimers, Dementia, Parkinsons and Epilepsy. Whilst there are many causes for issues in the brain, there are some common symptoms to look out for. Please remember though that having one or more of these symptoms might just mean your brain is not performing at its best and has ‘brain-fog’ and is not necessarily a symptom of a brain disease!

• Memory loss
• ‘Brain Fog’
• Lack of concentration
• Headaches
• Changes in personality
• Changes in mood
• Nausea
• Vomiting
• Fatigue

What Causes Poor Brain Health?

There is a whole range of potential causes of poor brain health; when it comes to many diseases, most of these are simply due to factors we cannot change such as age or genetics, but general issues with your brain such as a ‘brain-fog’, a lack of focus and difficulty remembering things could be caused by lifestyle. Here are some of the most common causes of issues with your brain health:

Foods For Brain Health

One of the best ways to boost your brain health and nutrition to clear ‘mind fog’ is to take care of your diet. Whilst a healthy and balanced diet will improve the health of your brain, there are also specific foods and ingredients you should be adding to your daily routine to give your brain a boost.

Fatty Fish

These are a rich source of Omega 3 fatty acids that are known to support brain health. Examples include salmon, cod, tuna and krill.

Plant-Based Omega 3 Sources

Also rich in Omega-3 for the brain but suitable for vegans and those that dislike fish. Examples of these include flaxseeds, chia seeds and algae oil.

Green Leafy Vegetables

These contain brain-health nutrients such as Vitamin K, lutein, folate, and beta carotene. Examples are broccoli, kale and spinach.

Hemp

As a natural source of Omega 3, hemp (unlike its psychoactive counterpart) is a safe way to boost brain health.

Berries

Rich in flavonoids that can help to improve memory. Examples include strawberries, raspberries and blueberries.

Dark Chocolate

Contains antioxidants that can help to protect the brain from free-radicals that can lead to oxidative stress and cognitive decline.

Whole Grains

These are a good source of Vitamin E which helps to nourish and protect the brain. Examples include brown rice, barley and oats.

Tea and Coffee

Thanks to the caffeine found in these, it can give an energy boost to help with concentration, focus and mental performance.

Eggs

These are excellent brain foods as they are a source of Vitamin B6, B12 and folic acid which help prevent brain shrinkage.

Avocados

As a source of healthy unsaturated fats, avocados can help with high blood pressure which is linked to cognitive decline.

Co-Q10

This ingredient contains B vitamins which contribute to the reduction of tiredness and fatigue and to psychological function.

Walnuts

A source of protein and healthy fats that can improve and support cognitive function as well as look after the heart.
