Background: In developing countries most of the edible salts have insufficient iodine content; the problem is worse in Africa. Only 15.4% of the Ethiopian population was using adequately iodized salt. Several factors affect iodine content of edible salt including poor handling practices. The existing evidence isn’t sufficient to detail the specific factors at the household level. Therefore, the...

Using urban household-level survey data from 1992 to 1998, we provide estimates of final demand for edible vegetable oils and animal fats in three regions of China based on the LinQuad incomplete demand system. For each region, the demand for the major “staple” oil is price inelastic. The demand for “condiment” or flavoring oils is more price responsive. All edible oils and fats have positive i...

Flavonoid contents as aglycones (for quercetin, kaempherol, isorhamnetin, luteolin and apigenin) were reported for 115 edible plants (91 species). Plant materials mostly originated in tropical zones were grown and harvested from AVRDC, Taiwan. Acid extraction and HPLC were used as analytical methods. Total flavonoid contents ranged from 0 to 254 mg/100g fresh weight. About 75% of samples were f...

Due to lack of comprehensive data on peri-urban domestic gardens, their potential value as luxury green space, provision of food, income and ecosystem services to the fast growing urban population in South Africa is not clearl...

In many animal species, male acoustic signals serve to attract a mate and therefore often play a major role for male mating success. Male body condition is likely to be correlated with male acoustic signal traits, which signal male quality and provide choosy females indirect benefits. Environmental factors such as food quantity or quality can influence male body condition and therefore possibly...
