Vitamins are natural components of foods and are organic compounds distinct from fat, carbohydrates and proteins. Vitamin A is the generic descriptor for compounds with the qualitative biological activity of retinol. Unlike beta-carotene, vitamin A is not an antioxidant and its benefit is related to its intimate relationship with immune reactions.

The effect of vitamin A on immune function is wide-reaching and its deficiency appears to affect immunity in several ways. Both the innate and adaptive immune responses are affected by lack of vitamin A.

QRBResearchers and contemporary nutrition scientists, media and individuals have long debated how and what our ancestors ate. One of the early proposals by Charles Darwin hypothesised that the hunting of game animals was a defining feature of early hominids, linked with both upright walking and advanced tool use and that isolated these species from their closest relatives (such as ancestors of chimpanzees); contemporised versions of this hypothesis exist to this day. Other insist that while our ancestors’ diets did include meat, it was predominantly scavenged and not hunted. Still others argue that particular plant foods such as roots and tubers were of greater importance than meat in the diets of these species. You know the routine, depending on the veracity of the proponent, one or other tends to become contextualised and propagated as the correct, or at least the closest to correct as someone can be in the 21st century.

Biodiversity from terrestrial, marine, coastal, and inland water ecosystems provides the basis for ecosystems and the services they provide that underpin human well-being. However, biodiversity and ecosystem services are declining at an unprecedented rate, and in order to address this challenge, adequate local, national and international policies need to be adopted and implemented.
