  Studies of dietary intake and status were collected from across Nigeria by literature search and personal contact with some country experts. Studies that satisfied a defined set of criteria; published, based on individual intakes and adequate information provided to enable its quality to be assessed were selected for further analysis. Twenty seven articles from four agroecological zones of the country were included and from them data on energy, protein, fats, carbohydrates, vitamins, minerals and trace elements were collected. Data on energy intakes were given in a large number of studies, but information was very limited for some micronutrients. Studies gave data on food patterns peculiar to their cultural and/or regional characteristics. A variety of collection methods were used, there was no consistency in the ages of adolescents studied or the age cut-off points, but some studies gave data for males and females separately at all ages. None of the study article was nationally representative and most of the remainders were regional. Apart from anthropometric measurements, status data were also collected from the four regions. Males had higher energy intakes than females. Variations in energy intakes and other nutrients related to energy intakes were not apparent across the regions within the country. In addition, most of the dietary studies did not rely on food composition tables for the conversion of food intake data to estimated nutrient intakes as there is no universally accepted food composition table across the country with a definite analytical methods, units and modes of expression. This can make comparisons between regions difficult and inaccurate. There are insufficient data on status to be able to be able to draw any conclusions about the nutritional quality of the diets of adolescents.

  Despite the fact that leaves of Vitex doniana has been in use for many decades in the treatment of many illnesses, little is known about its effect on serum electrolytes balance in mammals. This study sought to determined the effects of its aqueous leaves extract on serum electrolytes (sodium, potassium, chloride and bicarbonate ions) using standard laboratory methods, following 4 weeks oral administration to 30 albino rats at varied doses (100, 150 200 mg kg-1) with 10 albino rats as control group. The values of serum sodium, potassium, chloride and bicarbonate ions for the control group were 170±.00, 5.3±0.16, 130±2.00, 30±2.00 mMol L-1, respectively. However, significant increase (p<0.05) in serum chloride and bicarbonate ions was found at 100, 150 and 200 mg kg-1 and potassium ion at 150 and 200 mg kg-1, where as sodium ion at only 150 mg kg-1. It can be inferred that Vitex doniana leaves extract at dose of 150-200 mg kg-1 could be toxic. Therefore, like any other drug, it should be taken at a therapeutic dose to be determined, since it has been found to increase electrolytes level and may help in replenishing loses.
