Effects on infants fed breast milk contaminated with aflatoxin M1
Effects on infants fed breast milk contaminated with aflatoxin M1
Aflatoxin M1 (AFM1) is a toxic metabolite of aflatoxin B1 which is found in mother's milk. who eat contaminated foods such as grains, dried chilies, chili powder, peanuts, coffee, and dried foods. Exposure to aflatoxins in infants is of particular concern because of their negative effects on health and development. Especially for the brain Below is a detailed description of the negative effects:
---
1. Neurotoxicity and brain development
AFM1 was found to have neurotoxic effects. This impairs the growth and function of the baby's developing brain. during childhood The brain goes through an important period of growth. Including the creation of synapses. Myelin formation and neural network formation, AFM1 can disrupt these processes in several ways:
Oxidative stress: AFM1 induces oxidative stress by generating free radicals (ROS). Excessive oxidative stress can damage nerve cells. inhibits synapse development and impairs nerve signal transmission All of which are important for the development of intellectual and motor skills.
Inflammatory response: Exposure to AFM1 triggers inflammation in the brain. which leads to inflammation of the nervous system Chronic inflammation in the developing brain results in long-term impairments in learning, memory, and behavior.
Mitochondrial disorders: AFM1 can impair the function of mitochondria in neurons. This reduces the production of energy needed for brain development. This causes important processes such as axon growth and synapse formation to slow or stop.

2. Impairment of intellectual and behavioral development
Infants exposed to AFM1 experience delays in cognitive development stages such as language learning. problem-solving skills and memory. Animal studies have shown that exposure to aflatoxin causes brain shrinkage and decreased nervous system function. which manifests as short attention span Decreased learning ability and socialization challenges in humans
Neurotransmitter Imbalance: AFM1 can alter levels of neurotransmitters such as dopamine, serotonin, and glutamate, which are important for mood regulation. emotional stability and the functioning of the perception system
Effects on synapse plasticity: AFM1 impairs synapse plasticity. It is the brain's ability to adapt and reorganize in response to learning and experiences. As a result, children's ability to process and remember new information decreases.

3. Slow growth and nutritional deficiencies
Exposure to AFM1 often coincides with malnutrition. This is a common condition in regions with aflatoxin contamination. Malnutrition intensifies the effects of AFM1 by reducing the body's ability to detoxify and repair damage. Malnutrition also causes developmental delays and cognitive impairment caused by AFM1.
Disruption of the hormonal system: AFM1 disrupts the endocrine system. It affects the production of growth hormone, which is necessary for brain and body development.
Impaired Nutrient Absorption: Exposure to AFM1 damages the digestive tract. It reduces the absorption of important nutrients such as iron, zinc, and omega-3 fatty acids, which are important for brain development.

4. Carcinogenic potential and long-term effects
AFM1 is classified as a human carcinogen (Group 2B) by the International Agency for Research on Cancer (IARC). Although it is less carcinogenic than aflatoxin B1, long-term exposure during infancy increases the risk of cancer and chronic disease later in life. The developing brain is especially vulnerable to carcinogens and mutagens. This can lead to abnormalities in development or increase the risk of multiple sclerosis.

5. Epigenetic modifications
Recent research has shown that AFM1 can induce epigenetic changes such as DNA methylation and histone modifications. These changes can affect gene expression in the long term. This alters critical pathways for brain development and increases the risk of neurological disorders.

Prevention and relief
Breastfeeding guidelines: Mothers should avoid consuming contaminated food to reduce the transfer of AFM1 through breast milk.
Control of Dairy Products: Rigorous monitoring of milk and dairy products for aflatoxin contamination is essential. Especially in regions where there is a high risk of exposure to this substance.
Raising public awareness and educating the public: Educating caregivers about aflatoxin risks and how to avoid contamination is important for protecting infants.

Conclusion
Infant exposure to AFM1 poses a significant risk to brain development and overall health. Considering the fragility of the developing brain Even the slightest touch will have severe and long-lasting effects. Solving this problem requires a combination of public health policies. Food safety measures and educating caregivers to reduce exposure and protect infant health and development.
