Teenage Mental Health is
Associated with B-Vitamins

Teenage mental health is a hot topic, not only because of horrifying headlines, but also because 75% of adult mental illness will begin before a person reaches 24 years old.

Almost 50% of the adult population in Western countries will struggle with mental health disorders during some time in their life, making the statistics, and the social ramifications staggering.

It is well known that adolescent mental health disorders are more likely in teens with poor nutrition. So it is no surprise that in Westernized societies – societies that are increasingly consuming diets with poor nutritional profiles - mental health disorders are on the rise.

It is believed that developing young brains are more susceptible to nutritional deficiencies, making those teenage years particularly critical. To compound the problem, those are the years when children have more control over their own diet, and more potential to make poor food choices that sabotage their own health.

B vitamins in particular, are important for mood, energy and brain function. This is likely because they are involved in the production of neurotransmitters – the chemicals that are responsible for much of the communication in our nervous systems.

Wordle: B vitamins mental health

In a recent paper published in Preventative Medicine, researchers in Australia looked at the diets of 835 adolescents that were 17 years old, as well as their mental health and behavior. All data was collected via self-reported surveys.

There were many variables that could contribute to mental health that researchers had to consider. For example, adolescents with the highest scores for mental health and behavioral problems were more likely to exercise less often, have a higher BMI, consume more alcohol, come from a family with more discord, be from a lower income family, and have a mother who had been treated for a mental health disorder.

However, after researchers adjusted for these other variables, teenagers with low intakes of vitamins B1, B2, B3, B5, B6 and folate were more likely to exhibit behavioral problems. Specifically, inadequate consumption of these B vitamins was associated with “externalizing” behaviors like aggression and delinquency.

Low intake of vitamins B6 and folate were associated with “internalizing” behaviors such as depression, anxiety, or being withdrawn.

Previous studies have shown that young prisoners and delinquent school children show behavioral improvements with a B vitamin and mineral supplement.

Similarly, previous studies have also confirmed the association between low B6 and folate intake with depression. In fact, randomized controlled clinical trials have used folic acid to improve the efficacy of antidepressants.

While this study cannot prove that a vitamin B deficiency may be causing mental health or behavioral problems, when taken along with previous studies, it strengthens the link between nutrient intake and mental health.

It cannot be ruled out that mental health and behavioral problems are causing the individual to make poor dietary choices, and therefore the link demands further investigation.

It is also unclear whether these dietary choices during childhood, when brain function is still developing, have a lasting effect on mental health, or whether teenage mental health disturbances can be reversed later in life with dietary changes.

Raw spinach, broccoli, dulse, kelp, salmon, parsley, black beans, buckwheat flour, sunflower seeds, bananas, green peas and bee pollen are just a few great natural sources of B-vitamins.

What do you think about the link between diet and mental health? I know that my moods and energy are affected by my food choices, so could diet actually be therapeutic? Please share your experiences and opinions below…
