“…Availability of almost all biometals in the body is linked to the presence of vitamin C. Humans do not have the ability to create it, so they have to get it through the diet. The absorption of ascorbic acid depends on the amount of its input, whereby the method and temperature of storage and preparation of foods play a role in the vitamin C content [17][18][19][20].…”

The content of some biometals (Fe, K, Mg, Zn, and Mn), and two heavy metals (Pb and Cd) in nettle (Urtica dioica L.) and in the respective soils were determined by ICP-oES. The samples were collected from two locations in the vicinity of Niš and one from western Serbia. The amount of vitamin C in the samples was determined by iodometric titration. The aim of the study was to determine the percentage of fulfilling the daily needs for tested biometals and vitamin C by consuming nettle as tea or as vegetable, as well as to determine the amount of biometals that plants absorb from the soil. The obtained amount of Fe, K, Mg, Zn, Mn and vitamin C suggested that nettle can be used as an additional remedy in the treatment of anemia, and to alleviate the effects due to the lack of biometals. Some biometals were absorbed to certain saturation and some for as long as they were present in the soil.

“…However, unknowingly, these vitamins were generally present in the necessarily limited diets of sailors (8) (76) and also during the aforementioned trip by the Crozier party. However, unbeknownst to Scott, it was likely only the pony meat supplementing his sledging rations that provided a small supply of vitamin C (a few milligrams per person per day eaten) (100), especially as with rationing of cooking fuel the polar party ate at least some of this meat semi-raw (21) and thus did not cause so much decomposition of the vitamins or cause them to leach into the cooking water (2,101).…”

The 1910–1913 Terra Nova Expedition to the Antarctic, led by Captain Robert Falcon Scott, was a venture of science and discovery. It is also a well-known story of heroism and tragedy since his quest to reach the South Pole and conduct research en route, while successful was also fateful. Although Scott and his four companions hauled their sledges to the Pole, they died on their return journey either directly or indirectly from the extreme physiological stresses they experienced. One hundred years on, our understanding of such stresses caused by Antarctic extremes and how the body reacts to severe exercise, malnutrition, hypothermia, high altitude, and sleep deprivation has greatly advanced. On the centenary of Scott's expedition to the bottom of the Earth, there is still controversy surrounding whether the deaths of those five men could have, or should have, been avoided. This paper reviews present-day knowledge related to the physiology of sustained man-hauling in Antarctica and contrasts this with the comparative ignorance about these issues around the turn of the 20th century. It closes by considering whether, with modern understanding about the effects of such a scenario on the human condition, Scott could have prepared and managed his team differently and so survived the epic 1,600-mile journey. The conclusion is that by carrying rations with a different composition of macromolecules, enabling greater calorific intake at similar overall weight, Scott might have secured the lives of some of the party, and it is also possible that enhanced levels of vitamin C in his rations, albeit difficult to achieve in 1911, could have significantly improved their survival chances. Nevertheless, even with today's knowledge, a repeat attempt at his expedition would by no means be bound to succeed.

“…Ascorbic acid decreases gradually during storage especially at temperature above 0 o C [4]. Various ways by which we administer fruits or leafy vegetables containing ascorbic acid decreases their ascorbic acid retention, for instance, bruising, peeling, cutting into pieces and exposure to air decreases ascorbic acid retention [5,6]. Peeling apples may results in the loss of 8-25% of their ascorbic acid.…”
