We eat healthier, move more and take more breaks from our screens. But how do you take good care of your mental health from within? What we eat influences how we feel. One nutrient stands out in that respect: omega 3. Not as a quick fix, but as a structural part of a balanced lifestyle. In this article you will read how omega 3, and especially DHA, plays a role in the functioning of your brain.
The brain and fat: a strong connection
Our brain is the most fat-rich organ in our body except for one: the fatty tissue itself. In an adult, the brain consists of about 60% fat. An important part of that is polyunsaturated fatty acids, such as DHA, a specific omega 3 fatty acid.
DHA (docosahexaenoic acid) is mainly found in the cell membranes of brain cells. This fatty acid contributes to the maintenance of normal brain function (with a daily intake of at least 250 mg of DHA). It underlines how important it is to get enough omega 3 daily for your cognitive health.
DHA is therefore not an ‘extra’, but a structural part of the brain. During pregnancy and the first years of life, DHA is of great importance for the development of the brain. DHA, taken by the mother, is an important building block for the brain of the fetus and of breastfed infants. But also in adulthood, and certainly as you get older, it remains an important building block of your brain.
The body does not produce DHA itself in sufficient quantities. That means you depend on your diet: mainly oily fish or high-quality omega 3 supplements.
What does science say about omega 3 and mental resilience?
Research into the relationship between omega 3 fatty acids and mental health has been going on for years. In scientific literature, you see associations between omega 3 in the blood and various psychological outcomes, such as mood and stress processing.
Important to mention here: these associations are still being actively researched and differ per study. In addition, we are not allowed to make medical claims about omega 3 and mental complaints. What we can say is that DHA makes a recognized contribution to the normal function of the brain and therefore fits into a healthy lifestyle.
What else can you do for your mental health?
Mental health is not determined by one factor, but is the result of how you live, think and relax. In addition to a nutritious diet, lifestyle in particular plays a major role. Regular exercise, even if it is just a daily walk, helps your brain process stress and promotes the production of endorphins: the body's own ‘happiness hormones’. And what about sleep? During your sleep, your brain processes stimuli and the nervous system recovers.
In addition, it helps to consciously structure your day with enough moments of rest, social contact and structure. Think of a walk without your phone, keeping a gratitude journal or simply making time for something that gives you energy. You build mental resilience by making small daily choices that support your well-being. Omega 3 fits within that total picture, as a building block for your brain, but it starts with taking good care of yourself, inside and out.
Conclusion
Omega 3 is not a quick fix for mental complaints. But it is a fatty acid that your body, and especially your brain, needs daily to function normally. DHA is an important building block of your brain and plays a role in its functioning. By being conscious about your diet, you build a solid foundation, mentally and physically.
