The Xenohormesis hypothesis, ..
Although there is considerable validity to this theory, there is accumulating evidence that this may not be the entire story. There are abundant examples of interactions between plant and animal molecules that cannot be readily explained by the “common origin” hypothesis. For example, why do some plant signaling molecules interact directly with animal enzymes and promote health despite having no apparent homolog or chemical relative in animals? One could argue that these molecular interactions are simply a fortuitous coincidence, with the vast majority of plant molecules being either toxic or producing no benefit to animals. Indeed, given the immensity of the chemical space occupied by plant secondary metabolites, such a view seems plausible. However, several factors suggest that selection, rather than mere coincidence, may be at work. Let us examine, as an example, members of one broad chemical class in plant foodstuffs that confer human health benefits: the polyphenols. The synthesis of polyphenols (and many other phytochemicals) is induced in plants by a variety of environmental stresses. Polyphenol content provides a chemical signature of the state of the environment. This chemical cocktail, when ingested, comes into intimate contact with the receptors and enzymes within the consumer. The fact that stress-induced plant compounds tend to upregulate pathways that provide stress resistance in animals suggests that plant consumers may have mechanisms to perceive these chemical cues and react to them in ways that are beneficial. We have coined the term xenohormesis to explain this phenomenon (from xenos, the Greek word for stranger, and hormesis, the term for health benefits provided by mild biological stress, such as cellular damage or a lack of nutrition).
but it's in accordance with the xenohormesis hypothesis.

The Xenohormesis hypothesis, which is a central item in these dissertations, mentions that changes in the lifespan of an organism can occur due to stress-inducible molecules from an other organism (for example secondary metabolites in plants).
