New Research Shows Sugar Molecule in Breast Milk is Essential for Developing Brains and May Benefit the Elderly
Breastfeeding has always been known to have numerous benefits for both babies and mothers. Now, new research sheds light on an important sugar molecule found in breast milk that is essential for brain development. The study also suggests that this molecule may have positive effects on the elderly.
The sugar molecule in question is called myo-inositol, and it is not commonly found in cow’s milk but is abundant in human breast milk. Particularly in the first two months after birth, breast milk is rich in this micronutrient. Additionally, myo-inositol can also be naturally found in certain grains, bran, beans, citrus fruits, and melons.
According to the research, myo-inositol plays a crucial role in the formation of new synapses, which are neural connections in the brain. The scientists noticed a higher number of synapses being formed in the brains of breastfed infants. Furthermore, they observed an increase in the size of these synapses, indicating stronger connections. Notably, the effects of myo-inositol were consistent among breast milk samples collected from different regions, such as Mexico City, Shanghai, and Cincinnati, suggesting its importance regardless of ethnicity or background.
Dr. Thomas Biederer, a neurologist from Yale University, explains that the formation and refinement of these connections in the brain rely on genetic, environmental, and experiential factors. Diet is one of the environmental factors that can significantly impact brain development, especially in the first few months of a baby’s life. During this period, the blood-brain barrier, which prevents harmful substances from entering the brain, is more permeable, allowing small molecules, including myo-inositol, to easily pass from the bloodstream to the brain.
Breast milk production adapts dynamically in response to the different stages of a baby’s brain development. Dr. Biederer emphasizes that women worldwide have similar levels of myo-inositol in their breast milk, suggesting its crucial role in human brain development. As a result, the researchers propose adding myo-inositol to artificial baby food products to ensure infants who are not breastfed still receive sufficient amounts of this substance.
Interestingly, studies have also shown abnormalities in myo-inositol levels in individuals with mental disorders. Children with bipolar disorder or major depression tend to have lower levels of inositol in their brains, while Alzheimer’s patients and those with Down syndrome exhibit higher levels. However, researchers caution against making recommendations for adults until further research determines the reasons behind these abnormalities.
While many questions remain, such as the optimal levels of inositol at different stages of life and the potential risks of high levels in certain conditions, researchers are optimistic about the impact of studying myo-inositol and other micronutrients on brain health. Dr. Biederer and his colleagues hope that their ongoing research will lead to a better understanding of the interaction between diet and age-related brain abnormalities.
In conclusion, this new research highlights the importance of myo-inositol, a sugar molecule found in breast milk, in brain development. The findings suggest potential benefits for those who are unable to breastfeed and raise intriguing questions about its role in mental disorders and aging. As scientists continue their investigations, we may see advancements in formula production and a better understanding of the impact of diet on brain health.]
