Breast milk is often referred to as the "liquid gold" and for a good reason. Breast milk is the best food for babies in the first 6 months of life; it keeps them healthy and increases resistance. The benefits of breast milk go beyond just basic nutrition, as it provides a combination of vitamins, minerals, and other essential substances that promote healthy growth and development in babies. Moreover, breast milk also benefits mothers by helping in fast weight loss, release of oxytocin hormone and reduced risk of breast and ovarian cancer. Let us explore the nutritional value of breast milk and why it is considered to be beneficial for infants.Composition Breast milk contains the perfect balance of nutrients necessary for a baby's development. Its composition includes a variety of components such as proteins, fats, carbohydrates, vitamins, minerals, enzymes, and antibodies, all of which play crucial roles in an infant's growth.ProteinBreast milk contains two main types of proteins: whey and casein. The whey-to-casein ratio in breast milk is approximately 70:30, which is ideal for infant digestion. Whey proteins are easier to digest and contain antibodies like immunoglobulin A (IgA) that help protect the baby from infections. Furthermore, these proteins also aid in the development of the baby’s brain and nervous system.FatFat is a vital component of breast milk, which makes up about 50% of its calorie content. It provides energy and is crucial for brain development. Breast milk fats include long-chain polyunsaturated fatty acids (LCPUFAs) such as DHA (docosahexaenoic acid) and ARA (arachidonic acid), which are essential for the development of the baby’s brain and retina. CarbohydratesThe main carbohydrate in breast milk is lactose, which makes up about 40% of its calorie content. Lactose helps with the absorption of calcium and supports the growth of good bacteria in the infant’s stomach. Additionally, breast milk contains oligosaccharides, which are complex sugars that promote the growth of healthy gut bacteria and protect against harmful pathogens.Vitamins and MineralsBreast milk is rich in vitamins and minerals that are crucial for an infant's development. These include vitamins A, C, D, E, and K, as well as essential minerals like calcium, phosphorus, magnesium, potassium, and sodium. These nutrients are necessary for the development of bones, teeth, and the immune system.Other ComponentsBreast milk also contains many unique components that are not found in infant formula, giving it a significant advantage.Antibodies and Immune Cells Breast milk is packed with antibodies, particularly secretory IgA, which helps protect the baby from infections by forming a barrier on the mucous membranes in the intestines, nose, and throat. It also contains immune cells like leukocytes that fight infections directly.Enzymes and HormonesBreast milk contains various enzymes that aid digestion and absorption of nutrients. Hormones present in breast milk, such as leptin and ghrelin, help regulate the baby's appetite and energy balance.That’s not all, breast milk also helps in boosting the baby's immune system with antibodies and immune cells that protect against infections like respiratory and ear infections, as well as stomach illnesses. Breastfeeding also lowers the risk of chronic conditions such as obesity, type 2 diabetes, and heart disease later in life due to the good fats and nutrients it contains. Additionally, breastfeeding can reduce the risk of allergies and asthma by helping
