What Is an Oxidative Stress?
Oxidative stress is nothing but an imbalance between free radicals and antioxidants in the body. This can damage cells and tissues and has been linked to various health problems. In infants, oxidative stress has been linked to poor growth and development, but the relationship between oxidative stress and infant growth trajectories is not fully understood.
What Are the Oxidative Stress Markers Found in Milk?
Oxidative stress occurs due to an imbalance between the production of reactive oxygen species (ROS) and antioxidant defenses within the body. Biological processes and environmental factors can increase oxidative stress, contributing to cell damage and developing various diseases, like cancer, cardiovascular disease, and neurodegenerative disorders. Oxidative stress markers in human milk can provide insights into the oxidative status of lactating mothers and the potential impact on the health of breastfeeding infants. The most common oxidative stress markers found in human milk are listed below:
-
Malondialdehyde (MDA).
-
8-hydroxydeoxyguanosine (8-OHdG).
-
Glutathione (GSH).
All of these markers are produced when the body is exposed to oxidative stress and can be used to measure the level of oxidative stress in the body. Lipid peroxidation is a process that damages cell membranes by creating free radicals that react with lipids, leading to the formation of MDA (malondialdehyde) and other reactive aldehydes. Measuring MDA levels in human milk indicates the extent of lipid peroxidation. Similarly, the carbonyl content of milk proteins is another marker of oxidative stress since it reflects the accumulation of oxidized amino acids in proteins. Measurement of total antioxidant capacity (TAC) refers to the ability of a substance to scavenge ROS and prevent oxidative damage. The TAC of human milk can be measured by various assays, such as the oxygen radical absorbance capacity (ORAC) or the ferric-reducing ability of plasma (FRAP) assays. Antioxidant enzymes, such as superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx), also play important roles in protecting against ROS-induced damage. Measuring the activity or expression of these enzymes in human milk can provide additional insights into the oxidative status of lactating mothers.
Measuring oxidative stress markers in human milk can provide valuable maternal and infant health information. Elevated levels of oxidative stress markers in milk could indicate increased oxidative stress in lactating mothers, which could have implications for the health of the nursing infant. Conversely, high levels of antioxidant capacity and enzyme activity in milk could reflect a protective effect against oxidative stress. Further research is needed to fully understand the relationship between lactating mothers' oxidative status and breastfeeding infants' health.
How Stress Markers Impact the Infants?
Recent research has found that oxidative stress may affect infant growth trajectories. A study published in the Journal of Pediatrics found that infants with higher levels of oxidative stress had slower rates of weight gain and smaller head circumferences. Similarly, a study published in the Journal of Perinatology found that infants with higher levels of oxidative stress had lower birth weights and slower growth rates. Certain studies suggest that oxidative stress can affect specific aspects of infant growth trajectories. Oxidative stress was associated with slower fetal growth and lower birth weights but not with postnatal growth.
Overall, these studies suggest that oxidative stress may affect infant growth trajectories. However, more research is needed to fully understand the relationship between oxidative stress and infant growth and development. This research could potentially lead to new interventions to improve infant health and growth.
How Are Oxidative Stress Markers Detected?
Oxidative stress markers can be detected in human milk by laboratory testing. There are various markers used to measure the level of oxidative stress in human milk, including malondialdehyde (MDA), advanced oxidation protein products (AOPP), 8-hydroxy-2'-deoxyguanosine (8-OHdG), and total antioxidant capacity (TAC). A healthcare provider or lactation consultant prescribes a laboratory test to determine the presence of oxidative stress markers in the mother's milk. However, it is important to note that the presence of oxidative stress markers in milk does not necessarily indicate a problem with the quality or safety of the milk for the infant.
What Could Be the Treatment Options?
Treating oxidative stress can involve lifestyle changes, dietary changes, and supplements.
-
Lifestyle modifications like regular exercise, avoiding smoking and excessive alcohol consumption, and reducing stress can help reduce oxidative stress.
-
Eating a balanced diet that is high in antioxidants and avoiding processed foods can help reduce oxidative stress.
-
Supplements such as vitamin C, vitamin E, and coenzyme Q10 can also help to reduce oxidative stress.
-
Green tea, turmeric, and ginger being herbal remedy is highly beneficial.
-
It is important to get adequate sleep, as this can help the body to recover from oxidative stress.
-
It is also important to keep the body hydrated and reduce exposure to environmental pollutants.
By following the tips listed above, it is possible to reduce oxidative stress and improve overall health.
What Are the Ways to Prevent Oxidative Stress?
Following certain things keeps oxidative stress at bay. These include:
-
Eating a Healthy and Balanced Diet: A diet rich in vegetables, fruits, and whole grains can provide the body with the necessary antioxidants to fight oxidative stress.
-
Exercise Regularly: Doing physical activity in a regular manner can help reduce oxidative stress in the body.
-
Avoiding Smoking and Excessive Alcohol Consumption: Consumption of alcohol and smoking can increase oxidative stress in the body.
-
Managing Stress: High stress levels can lead to oxidative stress in the body. Therefore, finding ways to manage stress, like meditation or yoga, can help reduce oxidative stress.
-
Adequate Sleep: Getting enough sleep is important for reducing oxidative stress, as sleep deprivation can lead to oxidative stress in the body.
-
Taking Antioxidant Supplements: Antioxidant supplements like vitamin C, vitamin E, and CoQ10 can help reduce oxidative stress in the body. However, it is important to consult with a healthcare provider before taking any supplements to ensure they are safe and effective.
Conclusion
A recent study has examined the levels of oxidative stress markers in human milk, and the results are quite interesting. The study found that the levels of oxidative stress markers, such as malondialdehyde, were significantly higher in human milk than in the milk of other mammals. This suggests that human milk may be more prone to oxidative harm compared to other types of milk. Furthermore, the study also found that the levels of antioxidant enzymes, such as superoxide dismutase, were much less than in other forms of milk in human milk. This suggests that human milk may be less able to protect itself from oxidative damage. Overall, this study suggests that human milk may be more prone to oxidative harm compared to other types of milk and that antioxidant enzyme levels may be lower. This information could be used to inform health and nutrition strategies for infants.
