Concepts of health and disease in public health
Published in Sridhar Venkatapuram, Alex Broadbent, The Routledge Handbook of Philosophy of Public Health, 2023
Honeybees, which play an important role in human health through plant pollination, honey production, and its associated economic impact, are facing a crisis. There is a growing concern that the drastic global rise in colony collapse disorder (CCD) will result in severely depleted bee populations, which could have devastating consequences not only for beekeepers (and their bees), but for the environment more generally. As the name suggests, CCD is not a disorder of an individual bee. It is a disorder of the colony, whereby the majority of worker bees in a colony leave the hive and do not return. They abandon the queen bee, the honey they have produced, and the juvenile bees. This quickly results in a collapse of the colony.

Another point of discourse is the ever-present adage that “culture eats strategy for lunch” representing the persistence of resistance to change (Drucker, 2018). Although we acknowledge that culture is important, culture can be exclusionary, rejecting equity and exists to perpetuate itself and is destructive. Most readers are familiar with the “old boys’ club” and the phenomenon of the “queen bee.” The former is the historically driven exclusion of women from the professional domains of power that intersect with the personal networks reserved only for men and excludes those deemed to be minorities. The term “queen bee” (informal meaning of a woman who has a dominant or controlling position in a particular group or sphere) (Oxford Language, 2021) often refers to a woman of power who exerts influence in being the “first and only” and envelopes herself in the culture of the “old boys club” with the aim of limiting the acceptance of other women and underrepresented individuals. This phenomenon is in line with the practice of “tokenism” described in Chapter 7 and often feeds divisiveness, blocking progress. Thus, in the discussion of the framework for action, mentorship of women by women is emphasized and supported by the Social Action theory presented later in the chapter (Mathad et al., 2019).

Royal jelly is a white or yellowish creamy substance secreted from the mandibular and hypopharyngeal glands of the worker honeybee Apis mellifera. It is the food of the bee queen throughout her life and also the food of all bee larvae during their first three days of life (132, 141–144). The consumption of this magical liquid by the queen bee generates many advantages such as their size, which is double in comparison to worker bees, a longer lifespan, and a better function of their reproductive system. It is suggested that royal jelly is a potent promoter of healthy aging and longevity, because it enhances overall health and fertility of queen bees (132, 141–142). Royal jelly prevents senescence of human tissues in cell cultures. However, clinical studies of the effect royal jelly on longevity in humans are scarce and are still not confirmed (132).

Honey bees are highly social insects in which a queen bee controls the colony of several thousand workers. This caste is also responsible for laying eggs and thus maintains the strength of the colony. The ovaries of a queen bee in the colonies fed with thiamethoxam and its metabolite viz. clothianidin (0.004 and 0.001 ng µL−1, respectively) for 36 days were 6.8% larger than the control. However, such queens had 20% fewer stored spermatozoa in their spermatheca in which the proportion of living vs. dead sperm was 9% lower (Williams et al.2015). Thiamethoxam at 8.56 ng bee−1 was reported to affect the physiology and reproductive system of A. m. carnica queen bees (Gajger et al.2017). It was reported that the queen bees developed from the larvae fed with thiamethoxam had lower body weight and spermatozoa in the spermatheca. These conditions may challenge the development of the colony.

In recent years, bee products have been used as an alternative to chemical drugs for the treatment of many diseases. Natural products that have been used since ancient times are of great importance to protect health and to treat diseases. Bee products are among the first natural products that come to mind in the treatment of diseases. When bee products are mentioned, the first ones that come to mind are honey, pollen, Royal jelly, propolis and beeswax. Bee products are known as the most important treatment options of modern medicine, especially with the increase in cancer cases as well as many diseases. Royal jelly is a special substance secreted by 5-15 day-old worker bees from the under-pharynx glands in their heads to feed the queen and young larvae. It has a characteristic odor of white cream color and buttery consistency. It contains essential fatty acids, amino acids, minerals, collagen, lecithin, vitamins A, B5, B6, C, D and E (Fratini et al. 2016; Asadi et al. 2019; Guo et al. 2021). The queen bee is daily fed only with Royal jelly, which is an important nutrient for the developmental period. Royal jelly have antibacterial, antitumoral, antiaging, immunomvdodulator, respiratory system (allergic rhinitis, asthma), pancreattis, premenstural syndrome, antiulcerative, accelerating bone fracture healing, hyperlipidemia, hair growth enhancer, aphrodisiac, spermatogenesis enhancer, antioxidant, cardioprotective properties (Ramadan and Al-Ghamdi 2012; Sorucu 2019). Now some countries, like Switzerland, Bulgaria, Brazil and Uruguay have defined national standards for this product (Ramadan and Al-Ghamdi 2012).
Epigenetics, nutrition and mental health. Is there a relationship?

The recognition that DNA can be modified by nutrition and diet is relatively recent, and the extent to which environmental factors influence gene expression is still unclear. However, this is currently an area of very active research where many animal and insect models have provided interesting insights. The honey bee (Apis mellifera) provides a classic example of how diet during development can induce epigenetic DNA methylation and direct differential gene expression.35–39 Sterile worker bees and the fertile queen are different forms of genetically identical larvae. This dimorphism arises after larvae destined to be queen bees are preferentially fed a diet consisting of royal jelly, while larvae destined to be worker bees are largely fed pollen, nectar, honey, and beebread.39,40 The differential diets trigger substantial behavioural, morphological, and physiological differences where worker bees take longer to develop, have smaller body size, a shorter life span, rear young, gather nectar, and are infertile.41,42 This effect has been attributed to the phenolic-rich diet of the worker bee, which modulates development by influencing expression of genes that induce changes in genomic levels of DNA methylation.39,43
