Like all living creatures, we’re products of the world we live in. We are what we eat, what we drink, what we absorb through our skin and what we inhale.
Every day, every one of us is in contact with hundreds of toxins. From plastic drinking bottles, to kitchen cleaning products, to the air we breathe; research clearly shows that this ‘toxic cocktail’ is harming our health [1]. Now scientists are discovering that these toxins might be negatively impacting our brain function too.
What does new research say?
Long-term exposure to environmental pollutants leads to cognitive declines.
A study published in 2018 in the Proceedings for the National Academy of Sciences found that long-term exposure to particulate matter, sulfur dioxide and nitrogen dioxide led to cognitive declines in study participants as they aged [2].
BPA impacts the neurology system.
Data shows that BPA, a common plastic ingredient, damages brain cells and affects mood and memory. It has also been associated with anxiety and hyperactivity and is now believed to be one of the risk factors for ADHD [3][4].
Chemical sprays in cleaning products may be neurotoxic.
A 2017 report in Neuroscience News shows that the chemicals hidden in everyday cleaning products can interfere with thyroid hormone, which plays a critical role in normal brain development [5].
How can we take better care of our brains?
To start, we can reduce our toxic load by doing things like choosing BPA-free plastics, avoiding chemical-based cleaning products and exercising when the air is at its cleanest.
We can also help heal our brain by giving it the nutrients it needs to fight back. Omega 3 fatty acids have many powerful health benefits for your body and brain, especially Docosahexaenoic acid (DHA), one of the most important omega-3 fatty acids.
What is DHA?
DHA is an omega-3 fatty acid found throughout the body. It forms a structural part of the central nervous system and makes up approximately 40% your brain. No wonder it’s so important! DHA is vital for brain development in infants and plays a significant role in memory and learning throughout our lives [6][7]. All age groups need DHA and it is absolutely essential for pregnant women.
How else does DHA help with brain health?
1. DHA helps our brain’s “plasticity”
This refers to our brain’s ability to modify itself, supporting our ability to learn, change behaviors, process emotions, and recover from brain injury or damage [8].
2. DHA fuels the growth of new brain cells.
Yes, our brains do continue to grow as we age! DHA helps our brains grow throughout infancy, childhood, adulthood and even older age [9].
3. DHA is critical to cellular development in our eyes
It helps us maintain healthy vision, positively affecting our mental cognition in turn [10].
How much DHA do I need?
You won’t be surprised to hear that, on average, we consume far less DHA than we should. A typical adult American diet contains less than 100mg of DHA per day. Yet most health organisations agree that 250-500mg/day of combined DHA and EPA (another fatty acid) is the amount adults need to maintain overall health[11].
- An additional 200mg/day of DHA is recommended for pregnant and nursing mothers.
- Studies show that doses of up to 200-2,200mg/day are helpful for reducing depression and anxiety.
- The American Heart Association recommends that people with coronary heart disease take 1000mg/day of combined EPA and DHA, while those with high triglycerides take 2000-4000mg/day[12].
How can you increase your DHA intake?
You can add DHA-rich foods to your diet, by eating:
-
Fatty fish (anchovies, salmon, mackerel, tuna and halibut)
-
Eggs (eggs naturally contain small amounts of DHA)
-
DHA fortified foods and supplement
