Study aim: To assess possible effects of gender and of the level of motor activity on the deficiencies of selected vitamins and minerals in young subjects.Material and methods: Four groups of physical education (PE) students (n = 15 each) were studied: sedentary men (SM) and women (SF), and physically active men (AM) and women (AF) engaged in endurance sports, all aged 18 - 24 years, were studied. Somatic measurements included body height and mass, and body fat content (by Durnin's method, from 4 skinfolds), the biochemical ones included concentrations of retinol, α-tocopherol, copper, zinc and iron in plasma.Results: Men had significantly higher retinol (p<0.05) and iron (p<0.01) levels than women. The AM and SF groups had significantly (p<0.05 - 0.01) higher plasma levels of copper and zinc than Group SM. Group AF had lower zinc levels than Groups AM and SF, that latter group having lower α-tocopherol compared with Group SM.Conclusions: Inasmuch the observed differences could be due to the respective intakes, the effect of motor activity and the associated increased elimination of minerals could not be ruled out.

Euphorbia hirta (Tawa-tawa), also known as “gatas-gatas”, is a hairy herb grown in open grasslands, roadsides and pathways. This indigenous plant is considered as one of the most popular folkloric treatment for dengue in the Philippines. When researched, Tawa-tawa was found to be able to promote cell production, and to prevent platelet destruction (Philippine Council for Health Research and Development, 2013). In this study, a new application of the plant was evaluated. This was as a natural supplement for ice cream production without the degradation of its essential compounds. Fresh leaves of E. hirta were oven dried and macerated to water for 48 hours. The obtained extracts were subjected to lyophilization to prevent potential degradation of plant’s essectial compounds. Ice cream formulation was added with the obtained powdered extract of E. hirta. Results revealed that the lyophilized extracts from E. hirta leaves contained flavonoids, alkaloids, phenols and saponins. Promising amounts of Vitamin B2 (5.02 mg/kg), Beta-carotene (9.8 mg/kg), Vitamin E (23.8 mg/kg) and Vitamin C (80.2 mg/kg) were also obtained. Meanwhile, the E. hirta supplemented ice cream was negative to Salmonella and a 16 CFU/g for Total Coliform Count was found. What is more, organoleptic testing for both taste and texture revealed excellent responses and very good aroma. The findings of the current study affirmed the feasibility of developing a naturally-based ice cream product supplemented with a medicinal plant like E. hirta. The results indicate that the developed ice cream is safer and healthier, hence could encourage everyone to enjoy the delights of eating ice cream without worry of gastronomic distress.
