B Vitamins Crucial for Brain Health and Preventing Birth Defects, Experts Say

B vitamins play a vital role in maintaining brain health throughout the life cycle and preventing serious birth defects, according to experts. With research showing high rates of B vitamin deficiency in Ireland, particularly among older adults, there is a growing call for mandatory food fortification to reduce the incidence of neural tube defects (NTDs) and enhance overall health.

Why this matters: The widespread B vitamin deficiency in Ireland has significant implications for public health, as it can lead to increased risk of stroke, cardiovascular disease, and neurodegenerative diseases. Addressing this deficiency through mandatory food fortification and awareness campaigns can have a profound impact on the health and wellbeing of the population.

The eight B vitamins – thiamine (B1), riboflavin (B2), niacin (B3), pantothenic acid (B5), biotin (B7),folate or folic acid, and B12 – are vital for various bodily functions, including carbohydrate metabolism, energy production, DNA creation and repair, and methylation reactions within cells. Deficiencies in these vitamins, especially folate, B12, B6, and riboflavin, can lead to increased risk of stroke, cardiovascular disease, certain cancers, neurodegenerative diseases, depression, and NTDs in babies.

Helene McNulty, professor of human nutrition and dietetics at Ulster University, emphasizes the critical role of B vitamins in brain health, stating,"B vitamins are absolutely vital for brain health throughout the lifecycle, right from the early stages of brain development in the womb through to protecting the aging brain. "McNulty's researchhas shown that folic acid supplementation in early pregnancy protects against NTDs, optimal B vitamin intake in older populations protects against cognitive decline, and children of women who took folic acid throughout pregnancy performed better in cognitive tests at ages three, seven, and 11.

Sinéad Curran, head of the Department of Clinical Nutrition and Dietetics at the National Maternity Hospital, highlights the importance of vitamin B6 for women's health, while Kathryn Stewart, registered dietitian at the Dublin Nutrition Centre, explains that B vitamins are water-soluble and must be consumed daily, as they are not stored in the body.

A 2021 study by Trinity College Dublin revealed that one in eight adults over 50 in Ireland is deficient in B12, and one in seven has insufficientfolate. These findings are particularly concerning since Ireland has one of the highest NTD rates in the world and over half of all pregnancies in the country are unplanned.

In light of this research, experts like McNulty are advocating for mandatory food fortification with folic acid to reduce NTDs and improve overall health. Over 80 countries worldwide have already implemented such measures, resulting in significant reductions in NTD incidence rates.

The importance of ensuring adequate B vitamin intake through a balanced diet, supplementation, and potential mandatory fortification is becoming increasingly clear as evidence mounts. By addressing these deficiencies, Ireland can take significant steps towards improving brain health across the lifespan and preventing devastating birth defects. As McNulty states, "The evidence is so strong – folic acid is a safe and simple measure that works."
