Pronounced “as-ta-ZAN-thin,” this word can be a mouthful at first. Even more of a mouthful is astaxanthin’s primary natural source, Haematococcus pluvialis, the microalgae that produces it as a protective antioxidant in response to light or other environmental stressors. Bright red in colour, this antioxidant bioaccumulates in organisms that eat it, and it is responsible for the pink to reddish hue of krill, shrimp, salmon, and even flamingos.

Astaxanthin is a potent antioxidant, with studies showing it provides significantly greater antioxidant protection than the carotenoids beta carotene, lycopene, and lutein as well as alpha-tocopherol, and thus it is considered one of the best agents for protecting cellular membranes.[1],[2],[3] Natural astaxanthin has been shown to be 20 times more potent than synthetic astaxanthin in eliminating free radicals.[4] Astaxanthin is not produced by mammals, so it must be obtained from the diet.[5]

If you’ve been too busy in clinic or with other activities that keep you from perusing research and following supplement industry trends, you may have missed the tremendous swing of interest to investigating the impact of Nrf2 and Nrf2-inducing substances on health.

Vitamin A Recap

journal-nutrition-imageA vitamin is a substance that makes you ill if you don’t eat it.” (Albert Szent-Gyorgyi, Nobel Prize in Physiology or Medicine, 1937).

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.
