Background • Every food item is a source for multi-

element exposure

• Food habit may have association with changes in

body element levels

• Such altered status of body elements may leads to

health disorders

• It is needed to assess concentration of elements in

subjects with chronic health hazard

• Such assessment is done by biological monitoring

Objectives of the study

To find out the influence of food habit on body levels of trace elements and in turn it’s effect on physical health of Mysore subjects.

MATERIALS AND METHODS

1. Subjects: The residents of Mysore city & surrounding villages (M:100 & F:76)

2. Samples: Teeth, blood, urine, scalp hair & fingernail3. Sampling places: Teeth: JSS dental college, Mysore Blood, scalp hair, fingernails and urine: Kamakshi,

Bassappa Memorial and Vickram Hospitals, Mysore.

4. Questionnaire: personal and sample characters were collected

5. Processing of samples:Washing: T, F - DDW, H, N, - DDW & Acetone-wit magnetic stirrerDrying: Hot air oven - 50C - 24hrDigestion: HNO3 & HClO4 (4:1), Kjeldhal apparatus – 80’C - 8 hr Make up to 10 ml with DDW and stored in refrigerator at 4’C

Statistical analysis: Mean, Standard Deviation, Student ‘t’ test.

Mean elements concentration for food habit and blood sugar level were computed in each sample & given in following tables;

FINDINGS

1.Rural vegetarian had lower Cd-B & Pb-B than non-veg.

2.Rural diabetics had higher Co-H & Fe-H than non-diabetics.

3.Urban diabetics showed lower Zn-FN, & higher Cd-FN,

Cr-FN, Cu-FN, Mn-FN, Ni-FN, Pb-FN & Pb-T.

4.Lower Zn & Higher Pb are due to food habit & environment;

is one of the casual factors related to diabetes.

5.Positive correlation exists between elements & diabetes.

1212

CONCLUSION 

Food habit affects/changes the elements level and causes elements imbalance leading to altered element metabolism, which may be one of the causal factor for diabetes.
