Formula milk powder, also known as a modified milk powder, is specially designed to be closer to the nutritional composition of breast milk. It starts with regular milk powder but adjusts its ingredients to better suit the needs of infants. For instance, it reduces the amount of casein protein and increases whey protein, which is more easily digested. The formula also replaces most of the saturated fats with vegetable oils, increasing the levels of unsaturated fatty acids. Additionally, mineral content is reduced to ease the burden on the kidneys of young children. Vitamins, essential amino acids, and other nutrients are added to make the formula more similar to human milk.
Protein in breast milk is mostly alpha-lactalbumin, which makes up about 27% of total protein. In cow's milk, alpha-lactalbumin only accounts for around 4%. This specific protein provides an amino acid profile that closely matches breast milk, improves protein absorption, and helps reduce the overall protein load, which is beneficial for the baby’s kidney function. Whey protein also contains compounds that support sleep and brain development, helping babies rest better and grow mentally.
DHA and AA are important components in infant formula. DHA stands for docosahexaenoic acid, often called “brain gold,†while AA refers to arachidonic acid. Both are polyunsaturated fatty acids that can be synthesized from linoleic and linolenic acids in the body. These nutrients play a key role in brain and vision development, supporting cognitive abilities and visual acuity in infants.
Vitamins A and D, along with iron and zinc, are essential for a baby’s growth. The calcium-to-phosphorus ratio in formula is typically 2:1, and vitamin D is added to help the body absorb calcium effectively, reducing the risk of rickets. Iron is crucial for preventing anemia, but excessive vitamin A can cause skin issues or even headaches, dizziness, and nausea. While adding more nutrients may seem beneficial, it's important to maintain a balanced approach.
Nucleotides are another key ingredient found naturally in breast milk. They contribute to a baby’s immune system and help fight off infections. Research has shown that breast milk contains about 72 mg of nucleotides per liter. Some infant formulas, like Gold Xikangbao, add the same amount to boost the baby’s resistance and overall health.
Linoleic and linolenic acids are essential for the body to produce DHA and AA, which are vital for brain development. If these fatty acids are present in sufficient quantities in the formula, the baby can naturally synthesize the needed DHA and AA. However, if they’re lacking, additional DHA and AA may be required. But adding them directly can lead to oxidation, which affects the taste and quality of the milk. Therefore, ensuring adequate levels of linoleic and linolenic acids in the formula is crucial for optimal development.
Lastly, some formulas avoid palm oil, which can interfere with calcium absorption and lead to constipation. Studies have shown that formulas without palm oil result in better calcium absorption and stronger bone development. Babies who consume such formulas tend to have softer stools, similar to those who are breastfed. This makes choosing a palm oil-free formula a healthier option for your baby’s long-term growth.
