hmm i had posted something earlier today but it's gone. must have timed out. anyway i was hoping to clarify if you mean you have diarrhea.. zinc deficiency can cause that and what with the cold and so on, i thought you might want a little more reading.. if you eat wheat, dairy, sugar, or high-phytate foods often, it can deplete zinc. also modern diets contain fewer zinc-rich foods so societally our levels are down.

Zinc deficiency is associated with an increased risk of gastrointestinal infections, adverse effects on the structure and function of the gastrointestinal tract, and impaired immune function21, 27–30

Are changes in food consumption patterns associated with lower biochemical zinc status among women from Dunedin, New Zealand?

(short answer, YES)
Reductions in red meat and increases in cereals in the diet may compromise the intake and bioavailability of Zn. In this cross-sectional study of 330 premenopausal New Zealand women aged 18--40 years, we have assessed the inter-relationships among dietary intakes (via computer-administered food-frequency questionnaire), biochemical Zn status, and anthropometric indices, and compared our results with earlier data. Fasting serum (12.00 (sd 1.36) micromol/l) and hair Zn (2.71 (sd 0.36) micromol/g) were lower than those for young Dunedin, New Zealand, women in 1973 (non-fasting serum Zn 18.6 (sd 4.6) micromol/l, hair Zn 2.99 (sd 0.35) micromol/g). Further, our mean serum Zn was at the 25th percentile of the US National Health and Nutrition Examination Survey (NHANES) (1976--1980) reference sample for women aged 20--44 years. Meat-poultry-fish contributed only 28 % total Zn in the present study, a level comparable with that from cereals-nuts-legumes (27 %), compared to about 40 % in 1989. Significant negative correlations existed between serum Zn and dietary [phytate]:[Zn] molar ratios (r -0.163, 35 % had diets with [phytate]:[Zn] >15, a level said to compromise Zn status...
