Quotes are from the news release (Diet lacking in zinc is detrimental to human, animal health: Even moderate zinc deficiency is bad for digestion) of the study "Subclinical zinc deficiency impairs pancreatic digestive enzyme activity and digestive capacity of weaned piglets." (Subclinical zinc deficiency impairs pancreatic digestive enzyme activity and digestive capacity of weaned piglets. - PubMed - NCBI)
"The trace element zinc has an impact on the essential metabolic functions of most living organisms. New research carried out by the Chair of Animal Nutrition at the Technical University of Munich (TUM) has found that even minimal zinc deficiency impairs digestion, albeit without any typical symptoms such as skin problems or fatigue. Hence, short-term zinc deficiency in the diet should be avoided."
"the accumulation of undigested food inside the gastrointestinal tract due to zinc deficiency results in feeling less hungry," says Brugger."
""We proved that there is a direct correlation between the amount of digestive enzymes inside the pancreas and zinc levels in the organism as a whole," explains Brugger. "Even short intervals of zinc deficiency in the diet should therefore be avoided. Given the similarities between a pig's organism and the human organism, we may draw the following conclusion when applying our results to the human body: an egg or two more once in a while can do no harm." Brugger advises vegans, vegetarians and older people to monitor their zinc intake. Among other things, a subclinical zinc deficiency in humans has been attributed to increased levels of inflammation markers and reduced immunocompetence."
From the actual study abstract:
"Pancreatic Zn concentrations and pancreatic activities of trypsin, chymotrypsin, carboxypeptidase A and B, elastase and α-amylase exhibited a broken-line response to stepwise reduction in dietary Zn by declining beneath thresholds of 39·0, 58·0, 58·0, 41·2, 47·5, 57·7 and 58·0 mg Zn/kg diet, respectively. Furthermore, carboxypeptidase B and α-amylase activities were significantly lower in samples with reduced pancreatic Zn contents. Coefficients of faecal digestibility of DM, crude protein, total lipids and crude ash responded similarly to pancreatic enzyme activities by declining below dietary thresholds of 54·7, 45·0, 46·9 and 58·2 mg Zn/kg diet, respectively. In conclusion, (1) subclinical Zn deficiency impaired pancreatic exocrine enzymes, (2) this response was connected to pancreatic Zn metabolism and (3) the decline in catalytic activity impaired faecal digestibility already after 1 week of insufficient alimentary Zn supply and very early before clinical deficiency symptoms arise."
