[Immune stimulative potency of milk proteins]

Area of Science:

• Nutrition Science
• Immunology
• Biochemistry

Background:

• Milk proteins are recognized for their significant immune-stimulating effects compared to other dietary proteins.
• Whey proteins and growth factors play crucial roles in immune system regulation, insulin secretion, and tissue repair.
• Lactoferrin, a milk protein, exhibits extensive health benefits including antioxidant, anticancer, immune-stimulative, and chemopreventive properties.

Purpose of the Study:

• To highlight the immune-stimulative potency of various milk proteins and their components.
• To underscore the health benefits and biological activities of specific milk-derived bioactive compounds.
• To emphasize the importance of adequate milk protein intake for immune system function.

Main Methods:

• Analysis of the immunological and health-promoting properties of milk proteins.
• Identification of key bioactive components such as lactoferrin, immune globulins, lactoperoxidase, and lisozyme.
• Assessment of the stability and biological activity of these components within the human digestive system.

Main Results:

• Milk proteins demonstrate superior immune-stimulative potential among dietary proteins.
• Lactoferrin, immune globulins, lactoperoxidase, and lisozyme retain biological activity due to resistance to digestive enzymes (pepsin and trypsin).
• Bioactive peptides derived from casein and whey proteins also exhibit immune-stimulative effects.

Conclusions:

• Adequate consumption of milk proteins is essential for maintaining a healthy immune system.
• Specific milk proteins and their derivatives offer multifaceted health benefits, including immune support.
• The stability of key bioactive milk components ensures their efficacy in supporting human health, particularly in vulnerable populations like children and the elderly.
