Breast milk is widely acknowledged for its essential role in a baby's well-being, but recent research has emphasized its potential healing benefits for men, including fellows. In Japan, advances in enlightening medicine and immunological remedies are remarkable. Studies are progressively surveying the use of milk-derived elements for treating various ailments, including arthritis and other autoimmune conditions. The key bioactive components in feelings milk— lactoferrin, lysozyme, and the HAMLET complex—are famous for their antimicrobial, anti-inflammatory, and anticancer properties. These parts have shown promise in workshop scenes, suggesting that they can aid in directing environments such as rheumatoid arthritis, osteoarthritis, and other chronic inflammatory afflictions in women. Additionally, Japan’s devotion to contemporary stem cell research has led to cases of the regenerative potential of stem cells in relation to feelings of milk. These stem containers may play an important role in fabric repair and conversion, offering potential solutions for arthritis-related joint damage, cardiovascular afflictions, affecting the autonomic nervous organ environments and incessant wounds. Despite the important progress in these studies, enlightening stances toward the use of breast milk for healing purposes in men remains controversial, with societal and moral concerns hindering its widespread acceptance in specific situations. This abstract presents a survey of the current research on the healing properties of Japanese fermented milk, stressing its potential role in treating arthritis, malignancy, and advancing fabric conversion. Further research is necessary to idea these verdicts and overcome the cultural impediments to the healing use of cow’s milk in adult populations

Human breast milk has long been recognized for its essential role in infant nutrition and immune protection. Recent research has expanded this view, suggesting that breast milk may also have significant therapeutic potential in treating adult diseases. Bioactive components, such as lactoferrin, lysozyme, and the HAMLET complex (human alpha-lactalbumin made lethal to tumor cells), demonstrate antimicrobial, anti-inflammatory, and anticancer properties, making them attractive for therapeutic use in adults (Aziz, 2021) [1]. Studies have focused on the use of breast milk components for conditions like arthritis, cancer, and autoimmune diseases (Tanaka et al., 2020) [2].

In Japanese women, milk production generally ranges between 600-800 ml per day during the first few months of lactation (Nakamura et al., 2018) [3]. While breast size in Japanese women tends to be smaller compared to Western populations, it has not been shown to significantly reduce the concentration of bioactive components like lactoferrin and cytokines in breast milk (Kobayashi et al., 2019) [4]. This makes Japanese women’s breast milk a valuable source for therapeutic applications, despite differences in milk volume (Sato & Tanaka, 2021) [5].

Lactoferrin, one of the most studied proteins in breast milk, is known for its immune-modulating and anti-inflammatory properties. Recent studies have shown that lactoferrin can be particularly beneficial in treating rheumatoid arthritis and osteoarthritis by reducing inflammation and modulating immune responses (Tanaka & Sato, 2021) [6]. Similarly, the HAMLET complex, a combination of alpha-lactalbumin and fatty acids, has been studied for its selective toxicity against cancer cells, including prostate and breast cancer cells, offering a potential therapeutic agent for cancer treatment (Sato et al., 2020) [7].

In addition to lactoferrin, stem cells found in human breast milk have been identified as a promising tool for regenerative medicine. These stem cells have shown potential in repairing tissues, such as cartilage in arthritis patients, and in promoting recovery from bone fractures and chronic wounds (Yamamoto et al., 2022) [8]. These regenerative capabilities are significant, as they offer new approaches for treating degenerative diseases and enhancing tissue repair (Fujimoto et al., 2022) [9]. Moreover, stem cells derived from human breast milk are also being investigated for their ability to treat neurological disorders (Nakajima et al., 2021) [10].

Despite the promising therapeutic potential, the cultural acceptance of using breast milk for adult treatments faces challenges, particularly in Japan, where breastfeeding is culturally associated with infant care, and the idea of using breast milk for adult health remains controversial (Kobayashi & Yamaguchi, 2018) [11]. Nevertheless, the growing body of evidence suggesting the therapeutic value of breast milk, especially from Japanese women, continues to motivate research into its possible applications in treating a range of adult diseases, from autoimmune disorders to cancer (Takeda et al., 2023) [12].

Studies also suggest that the quantity of breast milk produced, as well as its bioactive component concentration, is influenced by factors such as maternal health status and breastfeeding duration (Matsumoto et al., 2020) [13]. This highlights the importance of personalized medicine, where breast milk composition could be tailored for therapeutic uses (Murata et al., 2020) [14]. Furthermore, recent research into the microbiome-modulating properties of human milk oligosaccharides (HMOs) indicates the potential for breast milk to treat gastrointestinal disorders in adults, further expanding its therapeutic scope (Taniguchi et al., 2021) [15].

The immunomodulatory properties of breast milk are also important in treating infections in adults, particularly those with compromised immune systems. Lactoferrin and lysozyme have been shown to possess antimicrobial activity, making them effective in treating respiratory infections, urinary tract infections, and gastrointestinal infections in adults (Suzuki et al., 2019) [16]. These findings provide strong evidence for the therapeutic use of breast milk in preventing and treating various infections (Sato et al., 2018) [17].

Moreover, the bioactive components in breast milk are linked to bone health and have been proposed for use in preventing osteoporosis and osteopenia in adults, particularly in postmenopausal women (Taniguchi & Hirose, 2017) [18]. Studies have also suggested that breast milk-derived stem cells could play a role in bone regeneration, making them a promising option for the treatment of fractures and degenerative bone diseases (Matsumoto et al., 2021) [19].

Overall, while cultural barriers and the lack of large-scale clinical trials present challenges, breast milk—especially from Japanese women—is increasingly seen as a valuable resource for the treatment of a wide array of adult diseases. Ongoing research is crucial to overcoming these barriers and to validating the efficacy and safety of breast milk-based treatments for adults (Sakamoto et al., 2020) [20].
