According to a 2016 systematic review and meta-analysis, promises made by many commercial nutrigenomics services were not supported by good science at the time, fueling the core debate. This lack of robust evidence is central to the controversy with nutrigenomics, raising questions about its practical value and ethical implications for personalized dietary advice.

While a typical modern human body contains over 125,000 calories, a 2017 study concluded that, from a purely nutritional perspective, humans are surprisingly inefficient as a food source compared to other prehistoric prey. The question, is the human body nutritious, therefore, leads to a much more complex and dangerous answer rooted in biology, risk, and ethics.

According to a 2017 study published in *Scientific Reports*, the caloric value of a single human body is significantly lower than that of many prehistoric megafauna, providing surprisingly low nutritional return. This fact is a central piece of information when considering the question: does eating humans have any nutritional value, and why was it practiced historically?

According to recent UN data, an estimated 2.3 billion people globally faced moderate to severe food insecurity in 2023, highlighting the deep-seated inequalities in our food systems. This sobering fact compels us to ask **what ethical issues are related to nutrition** and to explore the profound moral consequences embedded within our everyday food choices.
