Compositional study and antioxidant potential of Ipomoea hederacea Jacq. and Lepidium sativum L. seeds

The present investigation has been carried out to find the proximate composition, amino acids, metal contents, oil composition as well as the antioxidant capacity of the seeds of Ipomoea hederacea Jacq. and Lepidium sativum L. Proximate composition indicated a great difference in oil (14.09\ub10.66, 28.03\ub11.05) and fibre (16.55\ub10.31, 6.75\ub11.20) contents for I. hederacea and L. sativum, respectively. Fatty acid profile indicated that oleic acid (19.50 \ub1 0.37, 30.50 \ub1 0.16) and linoleic acid (52.09 \ub1 0.48, 8.60 \ub1 0.38) are major fatty acids. \u3b3-Tocopheol and alfa-tocopheol (28.70 \ub1 0.14, 111.56 \ub1 0.37) were the most abundant in the seed oil of I. hederacea and L. sativum, respectively. Results of antioxidant assays like TEAC, FRAP and TRAP indicated that L. sativum has much greater antioxidant potential than I. hederacea

Risk Factors for Diarrhea in Children Under Five Years of Age Residing in Peri-Urban Communities in Cochabamba, Bolivia

This study examined the relationship between childhood diarrhea prevalence and caregiver knowledge of the causes and prevention of diarrhea in a prospective cohort of 952 children \u3c 5 years of age in Cochabamba, Bolivia. The survey of caregiver knowledge found that more than 80% of caregivers were unaware that hand washing with soap could prevent childhood diarrhea. Furthermore, when asked how to keep food safe for children to eat only 17% of caregivers reported hand washing before cooking and feeding a child. Lack of caregiver awareness of the importance of practices related to hygiene and sanitation for diarrhea prevention were significant risk factors for diarrheal disease in this cohort. The knowledge findings from this study suggest that health promotion in these communities should put further emphasis on increasing knowledge of how water treatment, hand washing with soap, proper disposal of child feces, and food preparation relate to childhood diarrhea prevention

Honey, a Gift from Nature to Health and Beauty: A Review

Benefits of honey are contributed by the composition of its elements such as glucose, fructose, glucose oxidase, vitamins and phenolic compounds. For health, honey can be used to treat wounds due to the antibacterial activity conferred by the hydrogen peroxide produced by glucose oxidase in honey. Anti-inflammatory, anti-oxidant, deodorizing and tissue regeneration activities in honey also help in the wound healing process. It can also be an alternative sweetener for diabetic patients to ensure compliance to a healthy diet. Moreover, honey exerts several effects such as lowering low density lipids and increasing high density lipids, thus reducing risk of atherosclerosis. In terms of beauty, honey can be used on skin and hair. It moisturizes skin through its natural humectant properties contributed by high contents of fructose and glucose. Honey treats acne on the skin due to its antibacterial activity, anti-inflammatory action and tissue repair. The hair can benefit from honey in such a way that the hair has abundance, and becomes easier to comb. However, there have not been as many studies regarding the use of honey in skin in comparison to its use for health. Therefore, future studies on honey could research its use, action and benefits in both cosmetics and dermatology

Flavonoid Occurrence, Bioavailability, Metabolism, and Protective Effects in Humans: Focus on Flavan-3-ols and Flavonols

Flavonoids are profusely abundant in the human diet and might be responsible for the advantages ascribed to dietary regimens rich in plant foods. Notwithstanding the evidence from epidemiological and cohort studies, an unambiguous and exhaustive pattern has not yet emerged regarding the mechanisms underlying their food-related health properties. It is now increasingly evident that the sole direct action of substances available in planta is not sufficient to fully explain the benefits of polyphenol-rich dietary habits. To elucidate this conundrum, a better comprehension of the interplay between human and microbial metabolism and dietary polyphenols is needed. This chapter provides a detailed overview of the current knowledge on bioavailability and in vivo biotransformation of two widespread classes of flavonoids: flavonols and flavan-3-ols. According to data collected, these substances are not always endowed with the highest bioactivities in vivo, and a deeper knowledge of their metabolites is needed to properly assess their overall contribution to human health and to single out substances to be monitored for the exhaustive profiling of flavonoid bioavailability
