Introduction

Drinking pure milk during lactation benefits both mother and baby, offering advantages such as supplying high-quality protein, replenishing calcium, promoting breast milk production, enhancing immunity, and relieving fatigue. Pure milk is rich in high-quality protein, which is easily absorbed and utilized by the body. It provides essential nutrients for tissue repair and renewal in lactating women, and this protein can also be passed to the baby through breast milk.

Drinking pure milk during lactation benefits both mother and baby, with advantages including supplying high-quality protein, calcium supplementation, promoting breast milk production, enhancing immunity, and relieving fatigue. Detailed explanations are as follows:

1. Supplying high-quality protein: Pure milk is rich in high-quality protein that is easily absorbed and utilized by the body. It provides essential nutrients for tissue repair and renewal in lactating women. Additionally, this protein can be passed to the baby through breast milk, supporting the baby's growth and development.

2. Calcium supplementation: Pure milk is a good source of calcium. The calcium requirement increases during lactation, and moderate consumption of pure milk helps meet this need, preventing maternal symptoms such as back and waist pain caused by calcium deficiency. It also ensures sufficient calcium levels in breast milk, meeting the baby's needs for bone and tooth development.

3. Promoting breast milk production: Pure milk contains abundant water and nutrients. Adequate fluid intake helps maintain normal breast milk volume, preventing reduced milk supply due to dehydration and ensuring the baby’s feeding needs are met.

4. Enhancing immunity: Nutrients in pure milk such as vitamin D and B vitamins participate in metabolic processes and help strengthen the lactating mother’s immune system, reducing the likelihood of illness due to postpartum physical weakness.

5. Relieving fatigue: Lactating mothers often experience sleep deprivation and high physical exertion from caring for their babies. The carbohydrates in pure milk can quickly provide energy, helping alleviate fatigue and maintain better physical condition.

When drinking pure milk during lactation, it is important to choose fresh products and avoid consuming it on an empty stomach. If discomfort such as bloating or diarrhea occurs after drinking, consider warming the milk before consumption or consult a healthcare professional for advice on adjustments.
